Definitions
- the present invention relates to a helmet light for attachment to a protective helmet, wherein the helmet light can be switched into several different operating modes in which the helmet light emits light, and to a protective helmet with such a helmet light.
- a corresponding protective helmet which has a helmet shell with an interior that includes a component that touches the head and consists of at least a carrying basket, a headband and a neckband, and means for attaching this component to the helmet shell, is known, for example, from the document DE 87 14490 U1.
- This well-known safety helmet is a basic helmet that can be adapted to different tasks in different operating conditions by changing add-on elements.
- the safety helmet consists of a helmet shell and a minimum of interior fittings.
- the interior fittings consist of a cross strap with which the helmet is worn on the head and which ensures an impact-resistant distance between the head and the helmet shell.
- the safety helmet has a projection on its outer circumference that encloses the side and rear parts of the helmet and contains four recesses on the lower edge for attaching the cross strap and further recesses for attaching additional add-on elements.
- the basic version of the helmet can be used as a simple universal helmet without any add-ons. The add-ons can be added or removed as required.
- Helmet accessories that can be attached to the safety helmet include a helmet light, which, similar to a headlamp, provides additional illumination of the work area of a user of the safety helmet or other areas. Such additional illumination of the work area or other areas cannot not only be useful during dawn and dusk and after dark, but also in areas shielded from daylight, for example the twilight under a closed treetop.
- a helmet light that can be attached to the safety helmet can also be advantageous for a wide variety of activities. For example, night-time repairs to construction machinery on building sites or maintenance work in dark, poorly lit supply tunnels or under bridges can be carried out better and more efficiently if a suitable means of lighting in the form of a helmet light is carried "on the person" ready for use.
- an illuminated area of the lamp is constant and always moves in the same way with the helmet shell worn by the user when the user moves or turns his head.
- This means that a situation-adapted change in the illuminated area in particular requires manual adjustment of the position of the lamp fixed to the helmet shell relative to the helmet shell, which is usually difficult to achieve while a user is carrying out an activity, especially not without removing the helmet at least briefly, which represents a safety risk for the user.
- the object of the invention is to provide a helmet light for a protective helmet of the type mentioned at the outset and known from the first-mentioned document and to improve it in such a way that a more flexible use of a helmet light is possible without additional safety risks for the user.
- the helmet light according to the invention is designed so that the helmet light can be switched to several different operating modes, in each of which the helmet light emits light.
- a first operating mode of the several different operating modes the helmet light illuminates a facial area of a user of the protective helmet when the user is wearing the protective helmet.
- the area illuminated by the helmet light is therefore the facial area of the user in the first of the several operating modes and not, for example, a work area in front of the user, with the helmet light being able to switch between illuminating the work area in front of the user, for example. area and the illumination of the facial area.
- a complicated mechanical realignment of the helmet light which endangers the safety of the user, for example due to a protective helmet being temporarily removed, is not necessary.
- the different operating modes can differ in particular in that the helmet light illuminates different areas in the vicinity of the helmet light. Illuminating a facial area is particularly advantageous when a person opposite is to recognize the face of the user of the protective helmet, for example in order to be able to show the person opposite a "familiar" face in otherwise poor visibility conditions and not to appear as an anonymous faceless figure.
- the illumination of the facial area can be achieved by lighting elements that are arranged separately from a helmet light housing containing the actual helmet light in a face lighting unit. This face lighting unit can then, for example, be firmly positioned on an inner edge of the protective helmet, similar to the actual helmet light housing. It is also possible for the face lighting unit to be integrated directly into the helmet light.
- the helmet light illuminates a work area of the user of the protective helmet when the user is wearing the protective helmet.
- the user's work area can be considered to be the area of space directly in front of the user.
- the core area of the illuminated work area i.e. the light cone(s) emanating from the helmet light that directly illuminates an area, can, for example, start about 1 m in front of the user and end about 4 m in front of the user, assuming a height of the protective helmet worn by the user of 1.8 m and an orientation of the protective helmet "parallel" to the ground.
- a lateral opening angle, starting from the helmet light, of the core area of the illuminated work area can be about 160°, so that a wide area to the right and left lies directly within the light cone(s). From this, a main beam direction and a shape of the light cone(s) can be easily determined that directly illuminate the core area of the work area.
- the work area can also be defined more precisely in this way.
- the shape of the light cone(s) is determined by the Fresnel lenses used, each of which has a main beam direction and, if necessary, an "asymmetrical" beam angle.
- the illumination By illuminating the work area, a narrowly defined area in front of the user of the helmet light is illuminated, which simplifies his work, and at the same time prevents any possible glare for other people working near the user.
- the helmet light illuminates a close area of the user of the protective helmet when the user is wearing the protective helmet.
- the close area of the user can be seen as the area of space in front of the user that extends slightly beyond the work area into the distance.
- the close area can, for example, partially overlap with the work area and be illuminated in particular when the user wearing the protective helmet is walking.
- the core area of the illuminated close area i.e.
- the light cone(s) emanating from the helmet light that directly illuminates an area can, for example, start about 2 m in front of the user and end about 6 m in front of the user, assuming a height of the protective helmet worn by the user of 1.8 m and an orientation of the protective helmet "parallel" to the ground.
- a lateral opening angle, starting from the helmet light, of the core area of the illuminated close area can be around 120°, so that to the right and left an area that is slightly less wide than the work area lies directly within the light cone(s). From this, a main beam direction and a shape of the light cone(s) can be easily determined, which directly illuminate the core area of the close area.
- the close area can also be defined more precisely in this way.
- the shape of the light cone(s) is again determined by the Fresnel lenses used, each of which has a main beam direction and an "asymmetrical" beam angle if necessary.
- the helmet light illuminates a long-distance area of the user of the protective helmet when the user is wearing the protective helmet.
- the long-distance area of the user can be considered to be the area of space in front of the user, which extends far beyond the near area into the distance.
- the long-distance area can, for example, partially overlap with the work area and in particular be illuminated when the user wearing the safety helmet is walking or "looking into the distance".
- the core area of the illuminated long-distance area i.e.
- the light cone(s) emanating from the helmet light that directly illuminates an area can, for example, with an assumed height of the safety helmet worn by the user of 1.8 m and an orientation of the safety helmet "parallel" to the ground, start about 5 m in front of the user and end approximately at infinity, and even point upwards to the sky or run parallel to the ground, so that the illuminated core area does not formally end in front of the user, but extends to infinity.
- the light cone emanating from the helmet light hits the ground at a great distance, for example at a distance of 100 m.
- a lateral opening angle, starting from the helmet light, of the core area of the illuminated long-distance area can be about 60° or less, so that only a small area to the right and left lies directly within the light cone(s). From this, a main beam direction and a shape of the light cone(s) can be easily determined, which directly illuminate the core area of the long-distance area.
- the long-distance area can also be defined more precisely in this way.
- the shape of the light cone(s) is again determined by the Fresnel lenses used, each of which has a main beam direction and, if necessary, an "asymmetrical" beam angle.
- the helmet light comprises an external lighting module opposite a helmet light housing, which can be arranged on an outer side of a helmet shell of the protective helmet, wherein the lighting module has at least one helicopter LED, and wherein the helicopter LED emits light upwards in a fifth operating mode of the several different operating modes when the user is wearing the protective helmet.
- Upwards means that the light is emitted in the direction of the sky, assuming an upright user who is wearing the protective helmet correctly on his head. In this way, the user can be easily located from above, for example from a helicopter or a crane, so that the user's safety is increased because he is potentially better perceived and not overlooked.
- the lighting module has at least one further helicopter LED, which has a beam direction different from the helicopter LED wherein the helicopter LED and the at least one further helicopter LED emit light in different directions in a sixth operating mode of the several different operating modes.
- this always allows light to be emitted upwards, regardless of the head position of the user wearing the protective helmet.
- the LEDs are arranged on different opposite sides of the lighting module in such a way that they are also on different sides of the protective helmet, it is also possible to allow at least a rough recognition of the user's direction of view in the dark, for example if an LED on the "left" side of the protective helmet lights up green and the one on the opposite "right” side lights up blue.
- the helmet light's multiple operating modes can be switched in any combination.
- the helmet light can provide flexible illumination that is suitable for the respective application. Any combination is to be understood in such a way that multiple operating modes are present in combination with one another at the same time.
- a brightness and/or a color tone of the emitted light can be preset and/or set.
- Setting the brightness and/or the color tone can be referred to as changing the operating mode.
- the purpose of adjusting the brightness is obvious.
- adjusting the color tone for example to a stronger yellow tone, can also be advantageous depending on the working environment. For example, a high yellow content can improve the user's vision in fog.
- multi-colored LEDs can be used, which then have three different semiconductor crystals, each of which produces one of the three primary colors.
- the brightness and/or color tone of the emitted light can be varied over time. In this way, particularly in conjunction with the helicopter LED(s), an even better visibility of the user of the protective helmet can be achieved.

- FIGS 1 and 2a to 2f show three-dimensional views of a helmet light from different directions.
- Each helmet light 10 shown comprises a lens unit 14 with an anti-glare shield 124 arranged thereon and a main body, of which at least parts of a cooler element 20 and a cover element 22 can be seen in the figures.
- the cooler element 20 and the cover element 22 can, for example, be arranged on opposite sides of the main body of the helmet light 10, as can be seen in Figure 1, and can be fastened to one another, for example, by screws 23, each of which extends through the main body. It is also possible to additionally or exclusively glue the cooler element 20 and/or the cover element 22 instead of screw fastening.
- the cover element 22 can consist of one or more parts that are firmly or loosely connected to one another. In the example shown, the cover element 22 consists of a single part.
- the cooler element 20 is located on the side of the helmet light 10 facing away from the viewer and is largely covered by the cover element 22, which is why, in order to clarify the connection between the cooler element 20 and the cover element 22 and also to give the viewer an idea of the shape of the main body of the helmet light 10, covered areas of the cooler element 20 are shown in dashed lines in Figure 1.
- the helmet light 10 has a plug connection 3000 and a connecting plug connection 3002 on opposite lateral end areas.
- the plug connection 3000 can be a USB connection, for example, in particular a USB type C connection.
- a common arrangement on a single side of the helmet light 10 is also conceivable.
- connection connection 3002a in addition to the plug connection 3000, a connection connection 3002a is shown, which can be provided in addition to or as an alternative, in particular to the connection plug connection 3002, as required.
- the connection connection 3002a in Figure 1 is, for example, on the same side of the helmet light 10 on which the plug connection 3000 is provided.
- the connection connection 3002a is coupled directly to the main body of the helmet light 10 and, for example, is firmly soldered to a controller board 18 associated with the main body of the helmet light 10.
- connection plug connection 3002 and/or the connection connection 3002a can be used, for example, to connect accessories to the helmet light 10.
- Accessories for the helmet light 10 can be, for example, further light elements that can be freely positioned or fixed to a helmet shell 36, for example light elements that form a "helicopter LED", which is described in more detail below. Additional light elements that can be attached to the edge of the helmet shell in order to provide face lighting are also conceivable. Such face lighting can be particularly advantageous when rescuing people, since the protective helmet usually leaves the face of the wearer in the shadow, so that an already frightened person could possibly panic if they cannot recognize the user of the protective helmet approaching them or cannot recognize them as a normal person, and inadvertently hinder the rescue/recovery.
- the plug connection 3000 and the connecting plug connection 3002 can each, just like the connecting connection 3002a, be mounted on a circuit board carrying further electrical components of the helmet light 10, which is described in more detail below in the form of the controller board 18 by way of example.
- the lens unit 14 is regularly surrounded by the glare protection 124, which prevents or at least reduces unwanted escape of scattered light from the lens unit 14. In this way, for example, wearing the helmet light 10 in the activated state can be made more comfortable for a user, since light emerging from the lens unit 14 does not reach the user's eyes directly.
- the glare protection 124 can be made of rubber, plastic, GRP, a metal sheet, or a similar mechanically insensitive material that is impenetrable to visible light.
- the glare protection 124 can be removably fixed to the lens unit 14, for example by means of a clamping effect. In this way, for example, the glare protection 124 can be replaced in the event of damage.
- the glare protection 124 used to an glare protection 124 adapted to the respective intended use. It is conceivable, for example, that the glare protection 124 is provided in the radiation direction of the lens unit 14 in a manner not shown with an additional partially translucent element in order to modify a radiation characteristic/light intensity of the helmet light 10.
- the glare protection 124 can alternatively also be firmly and permanently connected to the helmet light 10, for example by gluing or a locking mechanism that cannot be released without causing damage.
- the helmet light 10 can also comprise a face lighting unit, not shown separately in Figure 1.
- a face lighting unit an area of the face can be illuminated by specially oriented lighting elements, which can be arranged separately from a "helmet light body" containing the helmet light 10 in a face lighting unit.
- This face lighting unit can then be firmly positioned on an inner edge of a protective helmet, similar to the actual helmet light 10.
- the face lighting unit can be integrated directly into the helmet light 10.
- the special lighting elements on the back of the lens unit 14 can be arranged in such a way that they emit diffuse light past the anti-glare protection 124 onto the user's face.
- a connection cable 24 can also be seen on the plug connection 3000, which ends at the end of the connection cable 24 opposite the plug connection 3000 in a connection plug 192, which is also described in more detail below.
- the helmet light 10 can be switched between several different operating modes, each of these operating modes being characterized by the fact that light is emitted by the helmet light, unless it is explicitly stated that one of the operating modes is to be the switched-off state of the helmet light.
- the several different operating modes can be characterized, for example, by the fact that different areas in the vicinity of the helmet light 10 are illuminated without the helmet light 10 being moved in its position or orientation. Examples include face lighting, close-range lighting, work area lighting, long-range lighting, a helicopter light and a position light.
- These individual different lighting modes of the helmet light 10 can also be used/controlled in any combination with one another, which further increases the number of different operating modes.
- the helmet light 10 can assume different operating states in each of the several different operating modes or can be operated in these. For example, an illuminance, i.e. a brightness of the emitted light, can be changed. This change can also be designed to be variable over time. In addition, a luminous color of the respectively controlled, light-emitting elements of the helmet light 10 can also be variable and adaptable.
- an illuminance i.e. a brightness of the emitted light
- This change can also be designed to be variable over time.
- a luminous color of the respectively controlled, light-emitting elements of the helmet light 10 can also be variable and adaptable.
- the helmet light 10 is shown three-dimensionally from above, so that in addition to the lens unit 14 with the glare protection 124, the connector plug connection 3002 on the left side and the connector plug connection 3000 on the right side, details of the cover element 22 can be seen.
- the cover element 22 has various elements which are used in particular for the detachable fixation of the helmet light 10 to the helmet shell 36 described in more detail below.
- the cover element 22 comprises at least four fastening points for mounting the helmet light 10.
- Figure 2a shows a rear holding claw 116, a front holding claw 112 and a holding element 122 on the left side.
- the cover element 22 also comprises a rear holding claw 118, a front holding claw 114 and a holding element 122.
- the cover element 22 in the example therefore comprises six fastening points, although more or fewer fastening points can be provided as long as at least four fastening points are provided.
- the functioning of the front holding claws 112, 114, the holding elements 122 and the rear holding claws 116, 118 is described in more detail below.
- the cover element 22 can be made from similar materials to the glare protection 124, whereby the cover element 22 is preferably made from an electrically insulating material, although this is not absolutely necessary.
- an unspecified on/off switch can be seen in the center, with the help of which it can be possible, for example, to switch the helmet light 10 on/off.
- this on/off switch is hardly accessible when the helmet light 10 is mounted on the helmet shell 36, this on/off switch can be considered optional, for example to address basic functions of the helmet light 10 when the helmet light 10 is held in the hand by a user and is not mounted on the helmet shell 36.
- the cooler element 20 which is particularly clearly visible in Figure 2b, faces away from the helmet shell 36 when the helmet light 10 is mounted and points towards the interior of the helmet.
- the cooler element 20 is provided with cooling fins 21 which improve heat dissipation and can dissipate heat generated when the helmet light 10 is in operation in order to prevent the helmet light 10 from overheating.
- a switch 120 is provided in the middle of the cooler element 20, which can also be used to easily switch the helmet light 10 on/off when the helmet light 10 is mounted. By operating the switch 120, the helmet light 10 can be switched from a completely switched off state into a kind of standby mode in which the helmet light 10 does not emit any light, but can only be controlled using external control elements.
- the cooler element 20 and the cover element 22 form, as already mentioned, essential parts of the outer surfaces of the main body of the helmet light 10.
- the cover element 22 and the cooler element 20 therefore also take on a mechanical see stiffening and protective function, wherein the cooling fins 21 arranged on the cooler element 20 and a circumferential bead on the edge of the cooler element 20 contribute to further stiffening.
- lens unit 14 in particular in Figure 2e, several individual, separate round lenses are indicated, which essentially serve for the directed light emission of the helmet light 10.
- the internal structure of the lens unit 14 with the lenses indicated here is explained below in Figures 4a and 4b.
- the curved shape of the helmet light 10 is also clearly visible in Figures 2e and 2f.
- the opposing regions of the main body of the helmet light 10, on which the plug connection 3000 and the connecting plug connection 3002 are arranged, are inclined relative to the central region of the main body of the helmet light 10 in order to adapt to a curvature predetermined by a helmet shell 36 in its intended mounting position.
- FIG 3a shows a three-dimensional isometric view of a helmet light 10 in an exploded view.
- the helmet light 10 visible in Figure 3a is shown in a simplified manner.
- a controller board 18 can be seen between the cover element 22 and the cooler element 20.
- the controller board 18 can be designed, for example, as a circuit board and in particular carry electronic components of the helmet light 10, which are connected to one another via conductor tracks arranged on the controller board 18.
- These electronic components can include, in particular, a control controller (not explicitly shown), which controls the various functions of the helmet light 10, for example switching between several different operating modes and states, as well as switching the helmet light 10 on and off.
- a small independent battery cell is provided on the controller board 18, which enables short-term emergency operation of the helmet light 10 without an external battery pack 100.
- This emergency operation can, for example, be limited to diagnostic operation and/or enable rudimentary light output, for example for 10 minutes.
- the controller board can carry a sensor unit (also not shown in detail) or have a connection option for such a sensor unit, so that sensors of various types included in the sensor unit can record, process and send data to the control controller.
- Possible sensors of the sensor unit can include infrared, ultrasound and twilight sensors. It is also possible to provide a backlight sensor and/or a gas sensor as part of the sensor unit.
- the sensor unit can also include an acceleration sensor.
- the sensor unit can also include a body temperature sensor and/or a humidity sensor.
- the sensor unit can also include a head detection sensor. It is also possible for the sensor unit to include a housing temperature sensor that detects a temperature of the helmet light 10.
- the sensors of the sensor unit can each be integrated into the helmet light 10 or, optionally only partially, provided as an external module, which can be arranged, for example, on the battery pack 100 or the ventilation slide 50.
- the control controller can, for example, be configured to receive a detected housing operating temperature value and to change an operating state of the helmet light based on the received housing operating temperature value. For example, the control controller can be configured to reduce a light output of the helmet light 10 if the detected housing operating temperature value of the helmet light 10 exceeds a tolerable temperature threshold value T to i_max.
- a reduction in the light output automatically means a reduction in the waste heat generated and thus a long-term reduction in the housing operating temperature value. This can, for example, prevent ignition of the combustible material in an explosive environment (flammable gases or dust in the air).
- the control controller can also be configured to switch off the helmet light 10 after issuing a warning signal if the detected housing operating temperature value of the helmet light exceeds an upper temperature threshold value Tmax. This may be necessary if, despite previously taken measures, a reduction in temperature could not be achieved and a further increase in temperature entails the immediate danger that the housing of the helmet light 10 will act as an "ignition spark" and could, for example, cause a dust or gas explosion.
- the control controller can also be set up to slowly bring the switched-off helmet light 10 into a selected operating state during a time interval At that is longer than the switch-on interval actually required to switch on the light-emitting elements, if the detected housing operating temperature value of the helmet light falls below a lower temperature threshold value Ti_euchte_min.
- control controller can be set up to ensure that the helmet light 10 actually emits light during the time interval At. light 10 to the desired light output in the selected operating mode. This also serves, for example, to reduce temperature gradients within the helmet light 10.
- the sensor unit can be configured to capture sensor data from the infrared sensor, process it, and send it to the control controller as processed sensor data.
- the control controller can in turn be configured to receive the processed sensor data and to switch the helmet light 10 between several operating modes and states based on the processed sensor data. Switching can occur whenever a predefined arm movement of a user wearing the protective helmet 30 is detected in the processed sensor data, for example waving in front of the lens unit 14 at a certain speed. In this way, the helmet light 10 can be easily controlled without the user needing to pay particularly close attention. If necessary, the user can even keep tools in their hand during the operating process.
- the infrared sensor can be arranged on the controller board 18, for example near the LED elements 1610.
- the infrared sensor is thus then arranged in the area of the lens unit 14 and thereby records sensor data essentially in an area in front of the lens unit 14. This enables the control panel to be restricted/defined so that unintentional activation of the helmet light 10 can be avoided.
- the sensor unit can also comprise an ultrasonic sensor, which can be arranged on the controller board 18 in a similar way to the infrared sensor near the LED elements 1610. The advantages described in connection with the infrared sensor can also be realized with the aid of the ultrasonic sensor in an analogous procedure.
- the ultrasonic sensor can therefore also be arranged in the area of the lens unit 14 and record sensor data essentially in an area in front of the lens unit 14. This again enables the control panel to be restricted/defined so that unintentional activation of the helmet light 10 can be avoided.
- the ultrasonic sensor may also be suitable for enabling operation by a user wearing special heat-insulating protective clothing. Switching can therefore take place, for example, if a predefined arm gesture of a user wearing the protective helmet 30 is recognized in the processed additional sensor data of the ultrasonic sensor.
- the sensor unit can also include a twilight sensor.
- the sensor unit can then be set up to record sensor data from the twilight sensor, process it, and send it to the control controller as processed twilight data.
- the control controller can in turn be set up to receive the processed twilight data and to switch the helmet light 10 between the multiple operating modes and states based on the processed twilight data, in particular to switch it on if insufficient brightness is detected in the processed twilight data in front of the helmet light 10.
- This enables partial automation of the operation of the helmet light 10, in particular automated switching on.
- sensor data is essentially recorded in an area in front of the lens unit 14, in particular in a work area. This enables the automatic operation to be restricted in such a way that the helmet light 10 is automatically activated, in particular switched on, only if insufficient brightness is detected in the area in front of the helmet light 10.
- the sensor unit comprises a backlight sensor
- the sensor unit can be configured to capture sensor data from the backlight sensor, process it and send it to the control controller as processed backlight sensor data.
- the control controller can in turn be configured to receive the processed backlight sensor data and to switch the helmet light 10 between the multiple operating modes and states based on the processed backlight sensor data. This also allows partial automation of the control of the helmet light 10. If the backlight sensor is directly hit by a light beam, i.e. the user is illuminated by another light source or another helmet light, it can be assumed that the helmet light 10 also directly illuminates the user of the other helmet light and possibly blinds them.
- the backlight sensor is expediently part of the sensor unit and is arranged in the area of the lens unit 14 on the controller board 18, so that backlight sensor data is essentially recorded in an area in front of the lens unit 14. Due to the usual arrangement of the helmet light 10 above the user's eye area, it can then be assumed that the detection of strong backlight in this area is also associated with a glare effect from the helmet light 10 for the wearer of the light source from which the backlight emanates. This is at least reduced. embellished by the helmet light 10 reducing its own light output when it detects backlight.
- the control controller can be set up to switch the helmet light 10 from an operating mode in which a high beam is active to an operating mode or an operating state in which a luminous range and/or intensity of the high beam is at least adjusted if it is detected based on the processed backlight sensor data that an incident backlight exceeds or falls below a threshold brightness.
- a reduction in the glare emanating from the helmet light 10 is possible in particular by reducing the light rays reaching into the distance, for example the high beam, by switching them off, reducing the intensity or changing the direction of the light so that the light is directed more towards the ground.
- the control controller can then be set up to only carry out the switching if the incident backlight permanently exceeds or falls below the threshold brightness for a time interval At, the time interval At being between 1 and 5 seconds, preferably between 2 and 3 seconds long. In this way, it can be prevented that a light beam that only casually touches the helmet light 10, which does not indicate a real, continuous glare of an opposite person, triggers an adjustment of the operating mode or operating state of the helmet light 10.
- Several different threshold brightnesses can also be predefined or set in the control controller. The control controller is then set up to adjust the light range and/or intensity of the high beam when one of the several different threshold brightnesses is exceeded or not reached.
- a direction in which other users are located can also be determined with the help of passive light sources, for example reflectors or similar, and/or position beacons that are worn by the other users.
- passive light sources for example reflectors or similar, and/or position beacons that are worn by the other users.
- the term "user” is to be interpreted very broadly here and includes in particular animals, for example dogs, especially working dogs, which, for example, assist in a tracking operation or more generally in a search in poor visibility conditions and which could possibly be distracted by strong, dazzling light sources during this search or tracking operation.
- the sensor unit can be configured to capture sensor data from the at least one gas sensor, process it, and send it to the control controller as processed gas sensor data.

- the control controller can then be set up to switch the helmet light 10 to an operating state in which a warning signal is issued if the processed gas sensor data show a concentration of CO2 and/or CO that is above a gas threshold concentration.
- the warning signal can be issued acoustically and/or optically.
- An acoustic output can be issued, for example, via a loudspeaker that can be coupled to the helmet light 10.
- the loudspeaker can, for example, be part of an input device that can be coupled to the helmet light 10.
- An optical output can, for example, mean adjusting the color of light emitted by the helmet light 10.
- the helmet light 10 can emit a red light or use it to illuminate the work area to indicate the danger.
- the sensor unit can also be set up to detect a concentration of a flammable gas via the gas sensor(s). Flammable gases can be ignited, for example, by the helmet light 10 itself or a tool operated by the user.
- the control controller is set up to switch the helmet light 10 to an operating state in which at least one warning signal is issued if the processed gas sensor data show a concentration of the flammable gas that is above a gas threshold concentration.
- the warning signal can be output acoustically and/or visually.
- the helmet light 10 can also be deactivated after the warning signal or at least the light output can be reduced. This can prevent an explosion or deflagration, since the heating of the helmet light 10 and the associated battery pack 100 may already be sufficient for an ignition/explosion.

- the main body of the helmet light 10 is protected below the helmet shell, so that conclusions can be drawn in particular about the head movement of the user based on the change in the movement trajectory. This is particularly advantageous for detecting a fall in the acceleration data.
- the sensor unit or acceleration sensor can detect acceleration in three directions that are not parallel to each other. This provides the most flexible data acquisition possible, allowing the detection of falls in any direction, for example.
- the control controller can be set up to switch the helmet light 10 to an operating state in which a position signal is output when the processed acceleration sensor data is above an adjustable acceleration threshold. If a fall of the user is detected, characterized for example by an abrupt acceleration in the z-direction (height), the position signal can make it easier to locate the user.
- the output of the position signal can in particular re include switching on the helmet light 10 if it was previously switched off.
- the output of the position signal of the helmet light 10 can also include the activation of position-indicating light elements, for example one or more helicopter LEDs 4000, 4002a, 4002b.
- the output of a position signal can also include a request to an input device coupled to the helmet light 10 to send a position signal.
- the transmission can, for example, include sending an emergency call via a radio communication channel, wherein the emergency call can also include GPS coordinates of the input device if the input device has these.
- Helicopter LEDs 4000, 4002a, 4002b can be activated in particular as part of a helicopter light, whereby the helicopter light further improves the visibility of the user, in particular from above, for example from a helicopter or a crane.
- the helicopter light is advantageous in all cases where the user of the helmet light should/must be seen by other people who are at a significantly different height, which is also the case, for example, when working on facades, excavation work in open pits, working in treetops and so on.
- the acceleration sensor or the data provided by the acceleration sensor can also be used to determine whether the user is standing (no variation in the z direction), walking (slow variation in the z direction due to the pendulum movement with each individual step) or running (fast variation in the z direction). Based on this, it is possible to control the helmet light 10 using the control controller in such a way that a "light range" of the helmet light 10 is adjusted depending on this variation in the z direction, for example work light when standing, close-range light when walking and high beam or high beam and close-range light when running. This can, for example, help to prevent the user from tripping.

- the body temperature sensor, or in the data recorded by it can in particular In particular, overheating or hypothermia of the user can be detected, which increases the user's safety, since the user cannot always detect these conditions in time. By switching the helmet light 10, the user can be informed of his condition, which could potentially endanger his own health. Switching can in particular also include switching on the helmet light 10.

- the helmet light 10 can comprise a fan unit and the control controller can in this case be set up to switch the fan unit on or off when the processed humidity sensor data exceeds or falls below a predetermined humidity threshold. Activating the fan unit associated with the helmet light 10 can generate an air flow, in particular under the helmet shell 36 of the protective helmet 30, in order to better remove any film of sweat that may be present, which increases the comfort of wearing the protective helmet 30 and lowers the user's body temperature.
- the fan unit can be arranged, for example, on the main body of the helmet light 10 or on the lower edge of the helmet shell 36. The fan unit is not shown in the figures, but it is obvious to a person skilled in the art how it must be designed so that it can generate an air flow beneath the helmet shell 36.
- the fan unit can alternatively also be arranged on or in the ventilation slide 50 and suck or blow the air flow through the ventilation openings 53 provided there.
- the fan unit can be supplied with electrical energy via the helmet light 10 or directly from the battery pack 100.

- the control controller can, for example, be configured to reduce a light output of the helmet light 10 if the detected housing operating temperature value of the helmet light 10 exceeds a tolerable temperature threshold value T to i_max. As a result, less electrical energy is converted into light, so that less waste heat is also generated, which increases the housing temperature.

- This procedure can directly contribute to preventing an explosion by presetting the temperature threshold value below an "ignition temperature", for example to 40° C.
- the temperature threshold value can be set differently in order to safely comply with legal requirements for explosion protection.
- the warning signal can again be issued optically or acoustically, for example, as already described above.

- the control controller can be set up to continuously increase the actual light output of the helmet light 10 during the time interval ⁇ t until it reaches the light output desired in the selected operating mode.

- the control controller can also be configured to activate an electrical heating unit arranged in a battery body 194 as long as the detected battery pack operating temperature value of the battery pack 100 falls below a lower temperature threshold value TAkku_min. In this way, the discharge cycle of the battery pack 100 can take place with the otherwise usual parameters.
- the control controller can also be set up to reduce the light output of the helmet light 10 if the detected battery pack operating temperature value of the battery pack 100 exceeds a tolerable temperature threshold value TAkku_max.
- TAkku_max a tolerable temperature threshold value
- the actions described above of the various sensors, the sensor unit comprising these sensors, and the control controller can also be viewed as a method carried out by these various elements of the helmet light 10. Furthermore, it is possible to adapt the behavior of the helmet light 10 to different purposes, for example by "reprogramming" individual or all threshold values, changing/adapting the recognized gestures/arm movements and the functions triggered by them, etc.

- a corresponding recess on the cooler element 20 is not visible, but can nevertheless also be provided for the connector plug connection 3002 to be arranged there.
- the cooler element 20 is connected in a flat manner to the carrier element 16 which it covers, so that heat generated during operation of the helmet light 10 from the controller board 18 passes through the carrier element 16, which is designed as a good heat conductor, to the cooler element 20 and is dissipated from there into the environment.
- Figure 3c shows another three-dimensional representation of parts of a helmet light 10 from above.

- unspecified through holes can also be seen, through which the cooler element 20 can be screwed to the cover element 22 when the helmet light 10 is mounted. The through holes therefore also extend through the carrier element 16.
- Figure 3d shows further components of a helmet light 10 three-dimensionally from above. Compared to Figure 3c, Figure 3d also shows the cover element 22 arranged on the controller board 18. The top side of the cover element 22 visible in Figure 3d with the on/off switch (not shown in more detail) faces the helmet shell 36 when the helmet light 10 is mounted.
- FIG 3e shows components of the helmet light 10 three-dimensionally from below.
- the cover element 22 lies on the underside of the helmet light 10, which faces away from the viewer, and the cover element 22 is therefore only partially visible.
- the cooler element 20 has not been shown, so that the carrier element 16 underneath is now visible.
- the controller board 18 is largely covered by the carrier element 16, so that only some edges of the controller board 18 are visible.

- the lens unit 14 has a number of directing units 1402 arranged next to one another. 7 individual directing units 1402 arranged next to one another are shown.
- the respective directing units 1402 serve to guide the light within the lens unit 14.
- the directing units 1402 are designed in the shape of a truncated cone, with each of the directing units 1402 being assigned to a separate LED element 1610 and guiding light emitted by the LED element 1610 from the back to the front through the lens unit 14, with as little stray light to the side as possible being desired.
- the various Fresnel lenses 1400a, 1400b and 1400c are designed differently, with the three centrally arranged Fresnel lenses 1400c each having different main radiation directions than the pairs of Fresnel lenses 1400b and 1400a arranged further out. It is of course possible to design the lens unit 14 with more or fewer pairs of directional units 1402 and Fresnel lenses 1400a, 1400b and 1400c. Furthermore, the intended main radiation directions of the individual Fresnel lenses 1400a, 1400b and 1400c can also be designed as required.
- the different main beam directions of the Fresnel lenses 1400a, 1400b and 1400c can be designed such that the Fresnel lenses 1400a are outer work light lenses, the Fresnel lenses 1400b are inner work light lenses and the Fresnel lenses 1400c are front light or high beam lenses.
- the lens element 14 can, for example, be designed as an injection-molded part made of transparent plastic with suitable light refraction properties. Individual Fresnel lenses 1400a, 1400b, 1400c can in particular also have the function of a diffuser.
- the various Fresnel lenses 1400a, 1400b, 1400c are used in the various operating modes of the helmet light 10 in different combinations to emit light in order to illuminate the light cones desired for the respective operating mode for illuminating the different spatial areas, in particular the work area, the close area and the long-distance area, around the helmet light 10.
- the user's work area can be considered to be, for example, the area of space directly in front of the user.
- a core area of the illuminated work area i.e. the light cone(s) emanating from the Fresnel lenses 1400a, 1400b, 1400c that directly illuminate an area, can, for example, start about 1 m in front of the user and end about 4 m in front of the user, assuming a height of the protective helmet 30 worn by the user of 1.8 m and an orientation of the protective helmet "parallel" to the ground.
- a lateral opening angle, starting from the helmet light 10, of the core area of the illuminated work area can be about 160°, so that a wide area to the right and left lies directly within the light cone(s).
- a main beam direction and a shape of the light cone(s) emanating from the "active" Fresnel lenses that directly illuminate the core area of the work area can be easily determined.
- the working area can be defined in this way, whereby the exact boundaries of the light cone(s) can still be modified depending on the application.
- the shape and boundaries of the light cone(s) are determined by the Fresnel lenses 1400a, 1400b, 1400c used, each of which has a main beam direction and, if necessary, an "asymmetrical" beam angle.
- the close range that adjoins the work area in the distance can, for example, partially overlap with the work area and can be illuminated in particular when the user wearing the protective helmet 30 is walking.
- the core area of the illuminated close range i.e. the light cone(s) emanating from the helmet light 10 that directly illuminates an area, can, for example, start about 2 m in front of the user and end about 6 m in front of the user, assuming a height of the protective helmet worn by the user of 1.8 m and an orientation of the protective helmet 30 "parallel" to the ground.
- a lateral opening angle, starting from the helmet light 10, the core area of the illuminated close-range area can be around 120°, so that to the right and left an area that is slightly less wide than the work area lies directly within the light cone(s). From this, a main beam direction and a shape of the light cone(s) can be easily determined, which directly illuminate the core area of the close-range area. The work area is thus closer and, just like the close-range area, sufficiently defined.
- the shape of the light cone(s) is again determined by the Fresnel lenses 1400a, 1400b, 1400c used, each of which has a main beam direction and, if necessary, an "asymmetrical" beam angle.
- the user's long-distance area can be defined as the area of space in front of the user that extends far beyond the near area into the distance.
- the long-distance area can, for example, overlap in parts with the work area and can be illuminated in particular when the user wearing the protective helmet 30 is walking or "looking into the distance", i.e. looking into the "distance” with his head raised. This can be detected, for example, with the help of a position sensor.
- the core area of the illuminated long-distance area i.e.
- the light cone(s) emanating from the helmet light 10 that directly illuminates an area can, for example, start about 5 m in front of the user and end approximately at infinity, and even point upwards towards the sky, with the illuminated core area not formally ending in front of the user, but extending to infinity.
- the light cone emanating from the helmet light 10 hits the ground at a great distance, for example at a distance of 100 m.
- a lateral opening angle, starting from the helmet light, of the core area of the illuminated long-distance area can be around 60° or less, so that only a small area to the right and left lies directly within the light cone(s).
- a main beam direction and a shape of the light cone(s) can be determined in a simple manner, which directly illuminate the core area of the long-distance area. Furthermore, the long-distance area can be sufficiently defined in this way.
- the shape of the light cone(s) is again determined by the Fresnel lenses used, which each have a main beam direction and a possibly have an "asymmetrical" beam angle.
- the lens unit 14 can further have areas at the lower edge of its rear side that allow diffuse light to emerge in the direction of the face of a user when an associated LED element 1610 emits light. This diffuse light can in particular make up the essential part of facial lighting.
- the lens unit 14 therefore comprises a plurality of Fresnel lenses 1400a, 1400b, 1400c, which are arranged essentially next to one another.
- the exact number of the plurality of Fresnel lenses 1400a, 1400b, 1400c can be adjusted as required.
- the plurality of Fresnel lenses 1400a, 1400b, 1400c can also be divided into a first and a second subset of Fresnel lenses 1400a, 1400b, 1400c.
- the first subset of Fresnel lenses 1400a, 1400b, 1400c can then emit light, for example, when a work area of the user of the protective helmet 30 is illuminated when the user is wearing the protective helmet 30.
- the second subset of Fresnel lenses 1400a, 1400b, 1400c can in turn emit light when a distant area of the user of the protective helmet 30 is illuminated when the user is wearing the protective helmet 30. In this way, different areas can be illuminated by the helmet light 10 without the helmet light 10 itself or a protective helmet 30 to which the helmet light 10 is attached being moved.
- Individual lenses of the plurality of Fresnel lenses 1400a, 1400b, 1400c can also include the function of a diffuser in order to counteract a possible glare effect. This can apply in particular to the components of the helmet light 10 that are used to illuminate an area of the user's face.
- Light can be emitted via a part of the first subset of Fresnel lenses 1400a, 1400b, 1400c, while at the same time light is also emitted via a part of the second subset of Fresnel lenses 1400a, 1400b, 1400c, for example in order to illuminate a close-up area of the user of the protective helmet when the user is wearing the protective helmet 30.
- a stepped, gradual transition in the illumination between the working area and the long-distance area can be achieved, for example in order to illuminate a close-up area between the working area and the long-distance area, which partially overlaps with the working area and the long-distance area.
- a glare protection surrounding the lens unit 14 can be provided in order to prevent light from the lens unit 14 from accidentally falling directly onto the user's face, in particular into the user's eyes.
- the Lens unit 14 can consist of a transparent material that attenuates yellow light the least in the visible frequency range.
- a cover 12 is detachably arranged in front of the lens unit 14 as part of the lens unit 14, which cover consists of a transparent material that attenuates yellow light the least in the visible frequency range. If the yellow component of the light generated by the helmet light 10 is attenuated the least, the yellow component in the emitted light is increased as a result, which appears "yellower".
- individual Fresnel lenses 1400a, 1400b, 1400c of the plurality of Fresnel lenses 1400a, 1400b, 1400c can have different main beam directions from one another. In this way, light generated by the helmet light 10 can be focused in different directions to illuminate different areas around the user of the helmet light 10. Individual Fresnel lenses 1400a, 1400b, 1400c of the plurality of Fresnel lenses 1400a, 1400b, 1400c can focus emitted light to different degrees.
- individual lenses can also act as scattering lenses that fan out light rays generated by LED elements 1610 in order to achieve less point-like illumination. This allows for different "bright” illumination as required and in particular also enables more diffuse illumination of an area, for example to counteract glare.
- FIG. 5a shows a controller board 18 of the helmet light 10.
- the controller board 18 has conductor tracks 1608, which are not shown in Figure 5a for the sake of simplicity. Only a few electronic elements in the central area of the controller board 18 are indicated. In particular, in the middle, a mechanical switching element 1612 is indicated, which can be provided for operating the helmet light 10.
- the lateral areas of the controller board 18 are shown as angled relative to the central area, whereby, in order to realize this angle, millings 1602 are provided, at which the controller board 18 can be bent into the desired shape.
- a large number of holes 1604 are also arranged distributed over the controller board 18, which can help, for example, during assembly when attaching the cooler element 20 and the cover element 22.
- LED elements 1610 are also indicated.
- the LED elements 1610 can vary in their number and in their properties.
- the lens unit 14 can be designed with "more" Fresnel lenses 1400a, 1400b, 1400c and the number of LED elements 1610 can be increased accordingly. be increased sufficiently.
- the LED elements 1610, or at least some of them, are colored LED elements 1610 whose light color can be adjusted.
- the controller board 18 can also comprise further LED elements (not shown) that emit light in the direction of a lower edge of the controller board 18 or the lens unit 14, which light emerges there as diffuse light and can make up the essential part of the facial lighting.
- Figure 5b shows a carrier element 16 of the helmet light 10 three-dimensionally from one side
- Figure 5c shows the same carrier element 16 three-dimensionally from the opposite side.
- Bends 1804 provided on the carrier element 16 can be seen, which delimit the central area of the carrier element 16 from the angled lateral areas, as well as various holes 1806, which can in particular correspond to the holes 1604 on the controller board 18 in their respective positions.
- a large recess can also be seen, with the help of which the switch in the form of a mechanical switching element can be arranged directly on the controller board 18 and at the same time is accessible through the carrier element 16.
- This recess is optional, however, and a possibly desired switch on this side of the controller board 18 or the helmet light 10 can alternatively be designed as a membrane switch without the recess.
- connecting lines are then routed around the carrier element 16 to the controller board 18.
- the carrier element 16 can, for example, be milled or punched from an aluminum sheet and bent into the desired shape.
- the carrier element 16 can, for example, be glued to the controller board 18 so that the controller board 18 and the carrier element 16 form a unit and heat emanating from the controller board 18 can be easily dissipated via the carrier element 16.
- Figure 6a shows a controller board 18 of a helmet light 10 from one side
- Figure 6b shows the same controller board 18 of the helmet light 10 from the other side opposite to the other side.
- the controller board 18 shown in Figures 6a and 6b also shows the plug connection 3000 and the connector plug connection 3002 on the opposite side angled area.
- Figure 6a shows an example of a mechanical switching element 1612 on the controller board 18 and the angled area facing away from the viewer.
- the LED elements 1610 arranged in the central region can also still be seen, as can an edge of a frame 1616, which is described in more detail in connection with Figure 6b.
- a further mechanical switching element 1614 can be seen, which is enclosed by the frame 1616, which can serve as an assembly aid for the carrier element 16 (centering function together with the central recess on the carrier element 16) and, on the other hand, protects the further mechanical switching element 1614 from impermissible forces.
- the frame 1616 can also frame other electronic components, for example capacitors and/or resistors, on the controller board 18 and protect them from mechanical forces.
- the side of the controller board 18 visible in Figure 6b can also be designed without the further mechanical switching element 1614 in an embodiment not shown, so that the associated/matching carrier element 16 can then optionally be designed without the central recess.
- a membrane switch can be provided, the connection of which is led around the edge of the carrier element 16 from the controller board 18 to the side of the carrier element 16 facing away from the controller board 18 in order to implement the function of the further mechanical switching element 1614 there.
- the mechanical switching element 1612 shown in Figure 6a can also be replaced, for example, by a membrane switch or another switching element.
- FIGs 7a, 7b and 7c each show a ventilation slide 50 of a protective helmet 30 from different viewing directions.
- Figure 7a shows the ventilation slide 50 from above.
- Figure 7b shows the ventilation slide 50 from the side and Figure 7c shows it from behind at an angle.
- the ventilation slide 50 is usually fixed in a displaceable manner to a helmet shell 36 of a protective helmet 30, for example clipped in with the aid of a locking device, wherein locking lugs of the locking device, which can be arranged on the ventilation slide 50, for example, are then movable/displaceable within a channel in a helmet shell 36 of the protective helmet 30 together with the ventilation slide 50 relative to the protective helmet 30, so that ventilation openings 53 visible in Figures 7a to 7c correspond to associated openings on the helmet shell 36 of the protective helmet 30, or are offset relative to them.
- the ventilation openings 53 are closed (by the material of the helmet shell 36) while in the other position, i.e. the matching position, the ventilation openings 53 are open so that an exchange of air can take place between the interior of the helmet shell 36 and the external space above the helmet shell 36.
- the ventilation openings 53 shown in Figures 7a to 7c The ventilation slider 50 shown comprises, in addition to the ventilation openings 53, a number of helicopter LEDs 4000, 4002a, 4002b arranged centrally.
- the helicopter LEDs 4002a and 4002b essentially point upwards when the user is standing, so that the user can be easily located from above in the dark.
- the helicopter LED 4000 is positioned at an angle relative to the two other helicopter LEDs 4002a and 4002b behind an edge 4004, so that the beam direction of the helicopter LED 4000 is also angled relative to the other helicopter LEDs 4002a and 4002b.
- the helicopter LED 4000 can also be used to locate the user from above when the user is leaning forward or when the user is lying down (for example after a fall).
- the helicopter LED 4000 can be viewed or used as a "position light" shining backwards.
- additional LEDs can be provided on the ventilation slide 50, for example to ensure that the user wearing a protective helmet 30 with such a ventilation slide 50 can also be located in lateral directions.
- additional LEDs on the sides of the ventilation slide 50 in different, easily distinguishable colors, the orientation or the direction of vision of the user can also be indicated at least roughly.
- a first LED arranged on a left side when wearing the protective helmet 30 can shine in a first color and a second LED arranged on a right side when wearing the protective helmet can shine in a second color that is different from the first color, so that a distant observer can see, even in the dark, whether the wearer of the protective helmet 30 is facing the left side of his head or the right side of his head, from which the observer can in turn deduce the approximate direction of vision of the wearer of the protective helmet 30.
- the helicopter LEDs 4000, 4002a and 4002b arranged in the ventilation slide 50 can, for example, be electrically connected to the helmet light 10, in particular via an electrical connection line which is, for example, connected to the helmet light 10 at the connector plug connection 3002 already known from Figure 1 or the connection connection 3002a.
- At least one battery cell can also be arranged on the non-visible inside of the ventilation slide 50.
- the ventilation slide 50 can also comprise a curved ventilation slide base that is not visible from the viewing directions shown, which essentially forms the inside of the ventilation slide and abuts with its edge on the inside of the outside of the ventilation slide, thereby forming a volume of space in the ventilation slide 50 in which the at least one battery cell is arranged. In this way, the battery can be encapsulated within the ventilation slide 50, so that it is even better protected.
- the ventilation slide 50 can also comprise an electrical connection that is used to connect the at least one battery cell to an electrical consumer and/or an electrical charging source.
- the electrical connection thus enables, just like the connection of the battery pack 100 described in more detail below, a standardized connection between the battery cell in the ventilation slide 50 and the helmet light 10 or another electrical consumer.
- the electrical connection can be arranged on a lower edge of the outside of the ventilation slide, so that easy access or an easy electrical connection option is realized.
- the electrical connection can be oriented and arranged in such a way that it can be moved together with the at least one locking lug in the groove on the helmet shell 36. In this way, it is possible to guide the connection cable 24 completely underneath the helmet shell 36 so that there are no outward-facing cable loops that could endanger the safety of the user.
- the electrical connection it is possible for the electrical connection to be oriented and arranged in such a way that it can be moved parallel to the at least one locking lug in another groove on the helmet shell 36. In this way, it is also possible to guide the connection cable 24 completely underneath the helmet shell 36 so that there are no outward-facing cable loops that could endanger the safety of the user.
- Magnets and electrical contacts can also be provided in connection with the electrical connection, the advantages being analogous to the respective features in connection with the connector plug 192 described later.
- the magnets make it possible in particular to facilitate the blind connection of the connector plug to the battery cell, since the magnets hold the components of the connector plug in pull into the correct position.
- a further electrical connection, separate from the electrical connection, can also be provided, which interacts with the electrical connection.
- the further electrical connection can be arranged on a lower edge of the outside of the ventilation slide so that it is easily accessible and a charger can be easily connected to the battery cell.
- the additional electrical connection includes magnets and electrical contacts.
- the magnets also make it easier to blindly connect a plug to charge the battery pack, as the magnets pull the components of the plug connection into the correct position.
- Figures 8a to 8i each show three-dimensional external views of a battery pack 100. The representations are partially simplified in order not to be dominated by insignificant details.
- Figure 8a shows the battery pack 100 in the deactivated state.
- the battery pack 100 shown in Figure 8a comprises a substantially elongated and cuboid-shaped battery body 194, the edges of which are bevelled, as shown in Figure 8a. Rounding the edges is also conceivable as an alternative.
- Figure 8a shows a display and control element 102 in the inactive state.
- a connector plug 192 can be seen, which is already known from Figure 1.
- the battery pack 100 can be connected to the helmet light 10 using the connector plug 192.
- the battery pack 100 is shown in its deactivated state, so that the display and control element 102 consequently displays "nothing".
- the display and control element 102 can be used to switch individual display elements on the display and control element 102 on and off and can also be "labeled” accordingly in order to identify the control element even when it is de-energized.
- Figure 8b shows the battery pack 100 from a side that is opposite the display and control element 102 from Figure 8a, so that the back of the battery pack 100 is visible.
- the back of the battery pack 100 can be structured in different ways as required.
- Figure 8c shows the battery pack 100 in an activated state.
- the display and control element 102 from Figure 8a which is not separately designated, displays various information for a user, in particular when the battery pack 100 itself is activated.
- the display and control element 102 can, for example, display a temperature 2000, an active charge level indicator 2002, and an on/off button 2004, optionally with an LED background lighting 2006.
- the display and control element 102 can have a display area 2008, under which an on/off switching element, in particular as a membrane switch, can be arranged, so that touching the displayed on/off button 2004 can, for example, switch the battery pack 100 or the connected helmet light 10 on and off.
- the temperature display 2000 can in particular graphically display the temperature of the battery pack 100.
- the display area 2008 can of course optionally also graphically display other or additional information about the helmet light 10 or the battery pack 100. For example, error messages from the helmet light 10 could be graphically displayed in the display area 2008 if the battery pack 100 is coupled to the helmet light 10 via the connector plug 192.
- a charging plug 190 can be seen below the connector plug 192 in Figure 8c.
- the charging plug 190 can, as shown in Figure 8c, be coupled to the battery pack 100 with an intermediate connector plug 192.
- the LED background lighting 2006 which is indicated in Figure 8c by hatching around the on/off button 2004, can also provide a "backlight function" for the user if required, for example, since the orientation of the battery pack 100 when mounted on the protective helmet 30 allows for corresponding functionality.
- one or more, in particular red, LEDs can be provided separately on the housing of the battery body 194.
- the external view of the battery pack 100 shown in Figure 8d corresponds to Figure 8c in terms of the viewing angle shown. Compared to Figure 8c, however, the battery pack in Figure 8d is shown in a different operating state.
- the LED background lighting 2006 is activated, which is indicated by the hatching used.
- the LED background lighting 2006 is deactivated, which is indicated by the absence of hatching.
- hatching visible in the area of the battery charge level indicator 2002 can visualize the current charge level of the battery pack 100.
- the temperature indicator 2000 can visualize the temperature of the battery pack 100, for example by means of a color change or in another suitable manner.
- the temperature display 2000 directly shows the temperature of the battery pack 100 in digits near or instead of the symbol shown in Figure 8d.
- the on/off button 2004 shown in Figures 8c and 8d can provide different functions.
- the on/off button 2004 can switch a helmet light 10 connected to the battery pack 100 on or off.
- the on/off button 2004 can, for example, put the battery pack 100 itself into different operating states. For example, it can be used to query at least some of the information that can be displayed on the display area 2008 and, in particular, to activate or deactivate the battery charge level indicator 2002.
- the functions provided by the on/off button 2004 can be changed depending on the plugs connected to the battery pack 100, i.e. the charging plug 190 and the connection plug 192, whereby an internal logic circuit of the battery pack 100 recognizes which plugs are connected to the battery pack 100 based on measurable voltages at the connection contacts of the battery pack 100, which are described in more detail below.
- the special design of the charging plug 190 and the connection plug 192 allows the connection plug 192 and the charging plug 190 to be connected to the battery pack 100 at the same time, so that in this way, for example, several batteries can be connected to the helmet light 10 of the helmet light system at the same time. It is also possible to charge the battery pack 100 while the helmet light 10 is in use.
- the helmet light system can comprise a transmitting and receiving module and an input device with a further transmitting and receiving module.
- the input device can then be connected to the helmet light 10 via the transmitting and receiving module and the further transmitting and receiving module in the form of a 2-way communication.
- This allows the helmet light 10 to be controlled via the input device and, conversely, the input device can also receive operating information from the helmet light 10 if the helmet light 10 is connected to the input device.
- the input device can be positioned as desired as an operating unit for the helmet light 10 and can in particular be arranged in the user's view, so that the operation of the helmet light system is simplified.
- the transmitting and receiving module and the further transmitting and receiving module can be radio modules or wired modules.
- the 2-way communication between the helmet light 10 and the input device can be established via a common communication protocol.
- the use of a common communication protocol also allows a more complex control of the helmet light system to be implemented, which can be achieved by simply closing an electrical circuit. to switch it on and off.
- the control of the helmet light system can therefore be flexible.
- the 2-way communication used can be protected by encryption. In this way, unintentional external operation by any input device that accidentally connects to the helmet light 10 of the helmet light system can be prevented. This is particularly useful when several helmet light systems, each with their own input devices, are used close to one another. In this context, the entry of a password can be provided to secure the connection.
- the operating information received by the input device can also include status information of the helmet light system. The input device can then output the status information of the helmet light system. This also makes it easier to operate the helmet light system.
- the helmet light 10 of the helmet light system can also be connected to another input device while it is already connected to the input device. It is possible that the helmet light 10 is then primarily controlled by the other input device.
- priority control can be carried out by an operations manager or a monitoring system installed at a location, for example switching on a camera, a helicopter light or a position light if the helmet light system has such options.
- the higher-level authority can also prevent individual operating functions from being switched off.
- the helmet light system which already includes at least one helmet light 10 with a control controller and can be switched to several operating modes and states by the control controller, can be supplemented with a camera unit, which is then functionally connected to the control controller.
- the control controller can activate the connected camera unit as soon as the helmet light 10 of the helmet light system is activated. It is also possible for the activation to take place while the helmet light system is in standby mode and is not yet emitting any light. This allows automated documentation of what the user of the helmet light system does and sees, and in particular it can prevent the user from forgetting to comply with any documentation requirements.
- the camera unit can store recorded videos internally. This allows for long-term archiving.
- the camera unit can also send recorded videos to the helmet light 10, for example for storage in a memory integrated in the helmet light 10. This also allows for long-term archiving.
- the control controller transmits videos recorded by the camera unit as operating information to an external storage device that can be connected to the helmet light system. In this way, a virtually unlimited documentation period can be realized.
- the external storage device can also be accessed by a third party, in particular for the visual representation of the video, for example in order to provide assistance to the user of the helmet light system in the event of a problem. For example, to guide the user through the problem.
- the helmet light system can comprise a headset via which the user can communicate with a third party who provides assistance.
- the communication can take place, for example, via a mobile phone connection, with the helmet light system being coupled, for example, to an input device that provides the mobile phone connection, for example a mobile phone.
- the control controller can be set up to adapt a recording direction of the camera unit depending on an operating mode and/or an operating state of the helmet light 10. In this way, the quality of the recordings made by the camera can be improved. In particular, a recording direction and a brightness of the recording made can be set.
- the control controller can also be set up to adjust a dynamic focal length of the camera unit depending on an operating mode and/or an operating state of the helmet light. This can also improve the recording quality of the camera. This can be done, for example, by adjusting the zoom, for example to expand or reduce the angle of view.
- the properties of the helmet light system described above can also be generally implemented and realized within the framework of a method for operating a helmet light system, which can then be carried out by the control controller of the helmet light.
- Figure 8e shows the battery pack 100 from behind, whereby, in contrast to Figure 8b, in addition to the connection plug 192, the charging plug 190 is also connected to the battery pack 100.
- the functionality of the plugs is explained in more detail below.
- Figures 8f and 8g show three-dimensional detailed views of a battery pack 100.
- Figure 8f shows a section of a top side of the battery pack 100
- Figure 8g shows a section of a side of the battery pack 100.
- a pair of locking lugs 212 can be seen on the top side.
- a lateral locking lug 210 is present on the side of the battery pack 100. If a lateral locking lug 210 is provided on one side, a further lateral locking lug can expediently be provided on the opposite side.
- the locking lugs 212 and the lateral locking lug 210 can interact in particular with a battery holder 214, which is described below, and fix the battery pack 100 in this battery holder 214 on the protective helmet 30.
- the locking lugs 212 and the lateral locking lug 210 are only shown in Figures 8f and 8g, but can also be provided on the battery packs 100 shown in the other figures.
- FIGS 8h, 8i and 8j show the battery pack 100 from different angles without the plugs connected.
- the battery pack 100 shown in Figure 8h is in a switched-off operating state, so that the display area 2008 does not display anything. However, it is also conceivable that the display area 2008 shows at least the on/off button 2004 even in the power-off state, for example in the form of a transparent film image.
- electrical contact surfaces 1112c are visible on a front side 1124 of the battery body 194.
- a notch-like recess 1114a is also visible, which serves to center the connection plug 192 or the charging plug 190 and at the same time prevents the plugs from shearing off the battery pack 100 at the side when mounted.
- FIG 8j shows the battery pack 100 from a different side, so that the recess 1114a on the front side 1124 of the battery body 194 is more clearly visible.
- the battery pack is shown in such a way that the further front side of the battery pack 100 opposite the front side 1124 is visible, which can, for example, be completely smooth. If required, however, further connection options in the form of electrical contact surfaces, guide elements or additional operating elements can also be arranged on this further front side.
- Figures 9a, 9b and 9c show three-dimensional representations of a connector plug 192 from different viewing directions.
- Figures 9a and 9c show a connection side of the connector plug 192 provided with an electrical contact 1108a.
- a projection 1116a which, together with the recess 1114a visible in Figure 8j, forms a guide element that helps in positioning the connector plug 192 on the battery pack 100.
- the projection 1116a centers the connector plug 192 together with the notch 1114a of the battery pack 100 on the battery pack 100. In this way, a blind connection of the battery pack 100 with the battery plug 192 can be made possible.
- Figure 9b shows a representation of the battery connector 192 from the side opposite the electrical contact 1108a.
- the electrical contact 1108a can comprise individual pin contacts. These pin contacts can, for example, be designed to be telescopically compressible, wherein in particular a pre-tension can be provided for the extended state of the pin contacts. In this way, when the connector plug 192 is brought together with the battery pack 100, an electrical contact closure can be reliably ensured by a resulting contact pressure, without there being any fear of bending of the electrical contact 1108a on the respective associated electrical contact surface 1112c, which can in particular be designed to be smooth or as a flat surface.
- the individual pin contacts can, for example, have spring-like elements in order to achieve the pre-tension. However, alternative designs are also known to those skilled in the art. This design also allows the plug to be pulled off the battery pack from the side.
- a recess 1114b is again provided on the side opposite the electrical contact 1108a, which is shown in Figure 9b, i.e. the back of the battery plug 192. Furthermore, an electrical contact surface 1112a can also be seen, wherein the electrical contact surface 1112a serves to electrically connect the connection plug 192 to the charging plug 190.
- the entire interior of the connector plug 192 can be cast using a casting compound 1110a.
- the casting compound 1110a then forms the housing of the battery connector 192.
- it can also be manufactured using housing shells, which are then tightly connected to one another in order to achieve a functionality analogous to that of the casting compound 1110a, in particular fluid tightness, of the housing.
- the provision of housing shells connected to one another can have advantages with regard to the interchangeability or control of the individual parts inside the connector plug 192, thus improving the environmental friendliness of the helmet light 10 as a whole.
- Figures 9d and 9e show a possible internal structure of a connector plug 192 from two essentially opposite viewing directions, so that a front side and a back side of the internal structure are visible. For the sake of simplicity, cable connections of the connector plug 192 leading away from the connector plug 192 have been omitted.
- the electrical contact surface 1112a can be seen on the opposite side. Both the electrical contact 1108a and the electrical contact surface 1112a extend through the potting compound to the surface of the connector plug 192, so that other elements on both elements can be electrically contacted with the connector plug 192.
- the magnets 1104a work together with corresponding counterparts in the battery pack 100 or the charging plug 190, so that reverse polarity of the electrical connections can be ruled out when they are brought together. This serves as an additional safety measure. Furthermore, the magnets 1104a, together with the corresponding counterparts on the battery pack 100, automatically pull the connector plug 192 into the correct position and ensure that the connector plug 192 and the battery pack 100 are held together securely even when there is mechanical stress in the direction of joining.
- the charging plug 190 also has a projection 1116b, similar to the connector plug 192. Furthermore, an electrical contact 1108b is also provided on the same side of the charging plug 190. Analogous to the connector plug 192, the housing of the charging plug 190 is also formed from a casting compound 1110b, whereby a fluid-tight structure made up of individual housing elements, in particular housing shells, is also possible here. On the side of the charging plug 190 shown in Figure 10a, which is opposite the side with the electrical contact 1108b, no electrical contact surface is provided, unlike the connector plug 192.
- the projection and the recess are each formed asymmetrically, preferably on an edge, of the respective connection surfaces. This provides a simple anti-twisting device.
- FIGS 10c and 10d show a possible internal structure of a charging plug 190 from two essentially opposite viewing directions, so that a front side and a back side of the internal structure are visible.
- a PCB 1106b of the charging plug 190 provided inside the charging plug 190 is shown, on which, analogous to the connection plug 192, electrical contact surfaces 1112b as well as an electrical contact 1108b and magnets 1104b are also provided.
- the structure of the illustrated PCB 1106b is thus largely similar to the structure of the PCB 1106a already known from Figures 9d and 9e. Since the PCB 1106b belongs to the charging plug 190, the PCB 1106b can have a different structure with regard to the illustrated electrical contact surfaces 1112b and the electrical contact 1108b, which in particular comprises fewer individual electrical contact pins of the electrical contact 1108b. This can be attributed to the fact that the charging plug 190 is usually attached last or is only temporarily connected to the battery pack 100, in particular while the battery pack 100, the connector plug 194 is already attached, which must "pass through" the electrical contact 1108b of the charging plug 190 to the battery pack 100.
- the PCB 1106b and the PCB 1106a are largely identical in their respective construction, but, depending on requirements, in particular fewer electrical connections are led outwards to the surface of the charging plug 190. This can reduce the number of different parts if the same PCB can be used for the charging plug 190 and the connector plug 192 and, for example, only the assembly of electrical components, such as the electrical contacts 1108a and 1108b, varies.
- Figures 11a and 11b each show a three-dimensional representation of a charging connection of a battery pack 100.
- the battery body 194 of the battery pack 100 is partially visible.
- the connection plug 192 is already attached in figure 11a.
- the connector plug 192 comprises a circumferential sealing lip 196 pointing radially inward with respect to an axial longitudinal extension of the battery body 194.
- the sealing lip 196 is located in the axial direction below a protruding circumferential collar 196a of the connector plug 192.
- the sealing lip 196 serves in particular to produce a sealing connection, i.e.
- FIG. 11a also shows charging contacts 198 and communication contacts 200.
- the charging contacts 198 and communication contacts 200 are located on the surface of the connector plug 192 enclosed by the sealing lip 196. Due to the arrangement of the charging contacts 198 and the communication contacts 200, a twist-proof assembly of the charging plug 190 (not shown) can be achieved.
- the special arrangement of the charging contacts 198 and the communication contacts 200 is to be understood as an example.
- the charging contacts 198 and the communication contacts 200 can be further subdivided. It is also conceivable that in addition to the charging contacts 198 and the communication contacts 200 shown in Figure 11a, further contacts are provided on the surface of the connector plug 192 enclosed by the sealing lip 196.
- the electrical contact surface 1112a for the charging plug 190 on the connector plug 192 is designed to be anti-twisting, for example, half of the charging contacts 198 and the communication contacts 200 can be brought together inside the connector plug 192 in order to achieve simple anti-twisting.
- the connection surfaces of the battery pack 100 and the connector plug 192 shown in Figures 11a and 11b each have no projection or recess, as described for example in the previous figures, in order to achieve anti-twisting. However, these can be easily supplemented.
- the upper part of the battery body 194 of the battery pack 100 is shown without the connector plug 192, which, analogously to the free end of the connector plug 192, comprises a sealing lip 208 arranged in an axial extension direction of the battery body 194 behind a collar 208a, which encloses a front side of the battery body 194.
- an electrical contact surface in the form of communication contacts 202 and connection contacts 206 is again indicated.
- the connection contacts 206 can be provided both for the electrical supply of a connected helmet light 10 with electrical energy and for charging the battery pack 100.
- the respective communication contacts 200, 202 and the connection contacts 206 or the charging contacts 198 are shown set back from the respective end face, i.e.
- the sealing lip 208 and the associated collar 208a are indicated on the front side of the battery body 194, which can hold the connector plug 192 on the battery body 194 in a desired connection position.
- the sealing lip 208 like the sealing lip 196 on the connector plug 192, ensures the water-protected electrical contact between the battery body 194 and the connector plug 192 that can be connected to it or the charging plug 190, if the latter is connected directly to the battery body 194 to charge the battery pack 100.
- the magnets 204 are shown in Figure 11b on the visible surface of the front side of the battery body 194. However, they can also be arranged invisibly under the protective outer shell of the battery body 194, i.e. inside the housing of the battery body 194, in particular to prevent corrosion of the magnets 204.
- the arrangement of the magnets 204 is optional. However, if the magnets 204 are present, they can, with a suitable selection of the poles pointing away from the battery body 194, not only serve to fix a plug to be connected in a desired position, but also provide an anti-twisting device, provided that the plug to be connected, the connection plug 192 or the charging plug 190, also has magnets with a suitable orientation.
- FIGs 12a and 12b show an internal structure of a battery pack 100 from different viewing directions.
- Two battery cells 1118 can be seen in Figures 12a and 12b. These battery cells 1118 have a conventional cylindrical shape in an axial direction of extension.
- a PCB 1106d and a cover 1122 that is electrically insulated or insulating from the PCB 1106d can be seen.
- the cover 1122 can be made of sheet metal, for example, and be electrically insulated from the PCB 1106d.
- Also indicated on the PCB 1106d are electrical contact surfaces already known from Figure 11b, although in an arrangement that differs from that in Figure 11b.
- PCB 1106c there is another PCB 1106c on the upward-facing surface of the battery cells 1118, on which a foil cover 1120 is indicated, which can have both a button and a display functionality for the battery pack 100.
- the button and display functionality of the foil cover 1120 was previously explained in connection with Figures 8c and 8d.
- the components shown in Figure 12b can, for example, be cast into the housing of the battery body 194 or integrated in another way in order to form the battery pack 100, as in the Mi- ture representation in the top right corner of Figure 12b, where the battery pack 100 is shown together with the connection and charging plugs 190, 192, which are not shown in more detail.
- the external shape of the battery pack 100 can of course be designed variably and in particular does not have to correspond exactly to the miniature representation.
- a battery pack temperature sensor can also be arranged inside the battery pack 100 or on its surface.
- This battery pack temperature sensor can detect a battery pack operating temperature value of the battery pack, which is transmitted to and received by a control controller of the helmet light 10, for example. Based on the received battery pack temperature value, the control controller can then change an operating state of the helmet light 10, for example to keep the battery pack 100 within a tolerable temperature range.
- the battery pack 100 also comprises an electrical heating unit that can be controlled by the control controller, in particular based on the received battery pack temperature value. For example, the control controller can switch on the electrical heating unit when the battery pack 100 falls below a lower temperature threshold value TAkku_min.
- the electrical heating unit can of course also be switched off in a temperature-controlled manner, advantageously in a hysteresis-like manner when another threshold value is exceeded that is slightly higher than the lower temperature threshold value TAkku_min.
- the control controller can also reduce the light output of the helmet light if the detected battery pack operating temperature value of the battery pack 100 exceeds a tolerable temperature threshold value TAkku_max.
- the electrical power taken from the battery pack 100 is reduced, which immediately reduces the waste heat generated, so that the temperature of the battery pack 100 can drop, assuming a constant rate of waste heat being released to the environment. This can be advantageous, for example, in an environment where there is a risk of explosion.
- FIGs 13a to 13h show various three-dimensional representations of a battery holder 214.
- the battery holder 214 which is shown at least partially in each case, comprises a frame 220 into which the battery pack 100 described above can be inserted in an axial insertion direction.
- the frame 220 of the battery holder 214 has a substantially cylindrical outer structure with a rectangular base area and rounded edges.
- the frame 220 is narrowed on one end face in the axial extension direction, so that the Battery pack 100 cannot enter or exit the frame 220 on this side.
- the battery pack 100 can be inserted into the frame 220 of the battery holder 214 from this side.
- the cylindrical structure of the frame 220 of the battery holder 214 allows the easy insertion of a battery pack 100 with a constant cross-section.
- the battery pack 100 can be fixed in the frame 220 of the battery holder 214 using an elastic tab 224. With the help of the tapering, a stop can be implemented when inserting a battery pack 100 into the battery holder 214, with the tab 224 arranged at the other end simultaneously clamping the inserted battery pack 100 within the frame 220.
- the frame 220 of the battery holder 214 encloses the space in which the battery pack 100 can be arranged in such a way that significant areas remain free, so that the battery pack 100 remains visible through the frame 220 of the battery holder 214. In this way, in particular, sufficient heat dissipation of the battery pack 100 during a charging/discharging process can be ensured, since the frame 220 does not additionally thermally insulate the inserted battery pack 100 from the environment.
- the frame 220 of the battery holder 214 is also connected to upper holding arms 216a and 216b.
- the upper holding arms 216a and 216b each lead to upper holding hooks 218a, 218b, which ultimately serve to attach the battery holder 214 to a helmet shell 36.
- the upper holding hooks 218a and 218b each comprise a step 223, the function of which will be explained in more detail later.
- Lower holding hooks 222a and 222b are also arranged directly on the frame 220 of the battery holder 214.
- the upper and lower retaining hooks 218a, 218b, 222a and 222b together serve to securely fix the battery holder 214 to a helmet shell 36.
- the exact interaction of the upper and lower retaining hooks 218a, 218b, 222a and 222b with the helmet shell 36 will be described in more detail later.
- the special design of the battery holder 214 described in Figures 13a to 13h serves to ensure the safety of a user of the protective helmet.
- the provision of the upper and lower retaining hooks 218a, 218b, 222a, 222b ensures that the battery holder 214 is firmly positioned on the helmet shell 36, but can still be easily removed if necessary.
- An object hitting the protective helmet 30 from above, such as a branch, can slide down the protective helmet 30. and in the event that it should become caught on the battery holder 214, the battery holder 214 can be released from the protective helmet 30 without the protective helmet 30 being torn from the head of a user wearing the protective helmet 30 and without the user experiencing the full impact force of the impacting object.
- the battery holder 214 can be easily attached to the helmet shell 30, since bending the upper retaining hooks 218a, 218b during the fastening process requires a comparatively small force. At the same time, this configuration keeps the force required to break the upper retaining hooks 218a, 218b comparatively small, so that the battery holder 214 can also be released simply and easily in an emergency, i.e. when an object hits the protective helmet 30 from above.
- Figure 14a shows a helmet shell 36 with a helmet light 10 in a frontal view.
- the viewing direction also shows the lens unit 14 of the helmet light 10, which is facing the viewer.
- a part of the fixation of the helmet light 10 to the helmet shell 36 is also particularly visible.
- the fastening points in the form of the front holding claws 112 and 114 which are already known from Figure 2a or 2c, for example, are hooked into a notch/groove 58 on a front edge 56 of the helmet shell 36. This is possible because the front edge 56 of the helmet shell 36 has a certain width, so that there is a surface there that can be notched.
- the two front holding claws 112, 114 of the helmet light 10 are hooked into the notch/groove 58 provided there during assembly, whereby for this purpose an elastic deformation of the front holding claws 112, 114 or the helmet shell 36 occurs when the helmet light 10 is pressed against the helmet shell 36 if the front holding claws 112, 114 are more elastic than the helmet shell 36.
- the elastic deformation is reversed and the front holding claws 112, 114 snap into the notch/groove 58 on the front edge 56.
- the helmet shell 36 is more elastic in the area of the notch/groove 58 than the front holding claws 112, 114, so that the elastic deformation during assembly takes place essentially at the notch/groove 58, while the front holding claws 112, 114 remain essentially dimensionally stable.
- Figure 14b shows a detailed view of a helmet shell 36 with a helmet light 10 attached to it.
- a different viewing direction is chosen compared to 14a, so that the helmet light 10 is shown "from below” and thus the helmet shell 36 can also be seen from “below”.
- Visible from the helmet light 10 are, among other things, the switch 120, the glare protection 124, the holding elements 122 arranged on the right and left sides and the cooling element 20 with its cooling fins and the surrounding bead.
- the curved shape of the cover element 22 ensures, in particular through the holding elements 122 arranged at the right and left ends, that the helmet light 10 clipped onto the helmet shell 36 cannot slip sideways but remains firmly fixed in a central position.
- the clipping takes place, for example, with the help of the front holding claws 112 and 114, which are not visible in Figure 14b, in conjunction with the rear holding claws 116, 118, which hook the helmet light 10 onto a reinforcing rib 62 of the helmet shell 36 on the side of the helmet light 10 opposite the front holding claws 112 and 114.
- Figure 14c shows a section of the helmet shell 36 from above.
- Figure 14d shows a section of a helmet shell with a helmet light attached to it from below.
- the front edge 56 of the helmet shell 36 and a structure on the surface of the helmet shell 36 in the form of profile lines that serve to stiffen the helmet shell 36 are particularly visible.
- the profile lines on the top of the helmet shell 36 can interact in particular with the aforementioned reinforcing rib 62 on the inside of the helmet shell 36 to achieve the desired mechanical stability.
- the helmet light 10 and the front edge 56 with the notch/groove 58 as well as the front holding claws 112 and 114 hooked into it are again more clearly visible.
- the notch/groove 58 on the front edge 56 also has a positioning aid for the helmet light 10 in the form of a web 110, which limits the mobility of the front retaining claws 112 and 114 in the notch/groove 58 on the front edge 56 of the helmet shell 36.
- Figure 14e shows a detailed view of the helmet shell 36 in section with the helmet light 10 attached to it, viewed diagonally from below.
- the helmet light 10 the glare protection 124, the front holding claw 112, one of the holding elements 122, the switch 120, the cooler element 20 with the associated cooling fins and the circumferential bead, the plug connection 3000 and the rear holding claws 116, 118 hooked into the reinforcing rib 62 are particularly visible.
- the helmet light 10 is first inserted with its rear holding claws 116, 118 into the reinforcing rib 62 and then the helmet light 10 is pushed upwards at an angle towards the front edge 56 of the helmet shell 36 so that the front holding claws 112 and 114 can each snap into the corresponding section of the notch/groove 58 on the front edge 56 of the helmet shell 36 after an elastic deformation of the fastening points involved and/or the helmet shell 36.
- the curved holding elements 122 also contribute to a reliable centered positioning of the helmet light 10 and can, for example, form a pincer-like structure with the front holding claws 112, 114.
- hooking onto another inner structure on the inside of the helmet shell 36 is also conceivable, which, however, is at least closer to the edge of the helmet shell 36 than the inner structure in the form of the reinforcing rib 62 into which the rear retaining claws 116, 118 hook.
- the reinforcing rib 62 also serves, just like the structuring visible on the top of the helmet shell 36 in Figure 14c, to stiffen the helmet shell 36.
- Extension-like branches 64 arranged from the reinforcing rib 62 on the inside of the helmet shell 36 can also contribute to the positioning of the helmet light 10 during and after its assembly on the helmet shell 36, since they can, for example, limit the possible positions of the rear holding claws 116, 118 when inserting the helmet light 10 on the reinforcing rib 62.
- FIG 15 shows a three-dimensional overall view of a helmet shell 36 with a helmet light 10 attached to it from below.
- a carrying basket 42 is indicated, which is described in more detail below and which is an integral part of a protective helmet 30 with the helmet shell 36.
- a clamping unit 48 should be mentioned, with the help of which the carrying basket 42 can be adjusted in size to a user's head size. can, especially when putting on and taking off.
- the helmet light 10 is shown attached to the "front" area of the helmet shell 36. Also visible in this front area is a face shield 32, which is connected to the helmet shell 36 via a bracket construction not described in detail in Figure 15 and is pivotably mounted on it.
- the battery holder 214 is indicated, which is intended to contain the battery pack 100.
- the helmet light 10 is coupled to the battery pack 100 in the battery holder 214 via the connection cable 24.
- the connection cable 24 can be firmly or detachably coupled to the helmet light 10, as was already explained in more detail in connection with Figure 1.
- the connector plug connection 3002 also already known from Figure 1, is also provided with a further connection cable 28 plugged into it.
- the connector plug connection 3002 with the further connection cable 28 arranged thereon can be used in particular to connect the "helicopter light" already described in more detail above to the helmet light 10.
- the battery holder 214 indicated in the rear area of the helmet shell 36 can be attached in particular to openings present in the helmet shell 36 via the upper holding hooks 218a, 218b only indicated in Figure 15, the lower holding hooks 222a and 222b of the battery holder 214 being covered by other elements of the protective helmet 30 in the illustration selected in Figure 15.
- Figures 16a to 16c show further detailed views of a section of the helmet shell 36 with the helmet light 10 attached to it from below. Many of the components of the helmet light 10 shown are already known from the previous figures.
- a pair of protective goggles 130 can be seen, which is also part of the protective helmet 30, to which the helmet light 10 and the helmet shell 36 also belong.
- the protective goggles 130 are fixed to the helmet shell 36 in such a way that they can be pivoted relative to it. In this way, they can either be pivoted out of the helmet shell 36, so that they essentially serve as eye protection for a user wearing the protective helmet 30, or they can be pivoted back under the helmet shell 36.
- the helmet light 10 is located essentially within the helmet shell 36 between the protective goggles 130 and the helmet shell 36, in particular the helmet light 10 is located in the free space which usually remains between the protective goggles 130 and the helmet shell 36 when the protective goggles 130 are pivoted back into the helmet shell 36.
- Figure 16b also shows the carrying basket 42, which, as seen from the helmet shell 36, is located even further "inwards" from the helmet shell 36, so that from the outside to the inside there is first the helmet shell 36, then the helmet light 10, then the protective goggles 130 and finally the carrying basket 42.
- FIGs 17a and 17b show detailed views of a section of a helmet shell 36 with a battery holder 214 attached to it from different viewing directions.
- the battery holder 214 is empty in each case, which means in particular that no battery pack 100 is inserted into the battery holder 214.
- the helmet shell 36 has openings which can be aligned with the ventilation openings 53, which in turn are provided on the ventilation slide 50, which was described by way of example in Figures 7a to 7c.
- the ventilation slide 50 is slidably fixed to the helmet shell 36 so that the openings on the helmet shell 36 can be made to coincide with the ventilation openings 53 on the ventilation slide 50 (are open) or are shifted against one another so that the openings on the helmet shell 36 are at least largely closed by the ventilation slide 50.
- the openings on the helmet shell 36 and the ventilation openings 53 on the ventilation slide 50 can in particular be arranged symmetrically to a plane of symmetry of the helmet shell 36 running from the rear, i.e. from the battery holder 214, to the front, i.e. to the helmet light 10.
- Figure 17a shows an open state of the ventilation openings 53 during assembly of the battery holder 214
- Figure 17b shows the closed state with the battery holder 214 assembled, in which the openings provided on the helmet shell 36 are largely covered by the ventilation slide 50.
- the battery holder 214 is inserted with the upper retaining hooks 218a and 218b through the ventilation openings 53 provided on the ventilation slide 50 and the associated openings on the helmet shell 36, so that a step 223 can rest on the edge of the respective ventilation opening 53 and the respective upper retaining hooks 218a and 218b can snap into place on the edge of the openings in the helmet shell facing the rear lower edge of the helmet shell 36.
- the lower retaining hooks 222a and 222b are pushed over the rear lower edge of the helmet shell 36, so that due to the existing elasticity of the material of the battery holder 214, which allows a certain elastic deformation, particularly in the area of the upper retaining arms 216a and 216b and the frame 220 of the battery holder 214, the Clip the lower retaining hooks 222a, 222b.
- a different sequence for mounting the battery holder 214 on the helmet shell 36 is also possible.
- the battery holder 214 can also first be hooked onto the lower edge of the helmet shell 36 with the lower retaining hooks 222a and 222b and then pushed forward/upward in such a way that the upper retaining hooks 218a and 218b pass through the ventilation openings 53 and the openings on the helmet shell 36.
- This state is visible in Figure 17a.
- the upper retaining hook 218a does not yet engage the lower edge of the opening in the helmet shell 36.
- the battery holder 214 is released, this changes, since the elastic deformation of the battery holder 214 is reversed and the upper retaining hooks 218a and 218b engage downwards on the edge of the openings in the helmet shell 36. Due to the step 223 provided, the displaceability of the ventilation slide 50 is largely retained, so that the openings provided on the helmet shell 36 can still be covered at least for the most part by the ventilation slide 50 and thus closed.
- the upper holding arms 216a, 216b allow the greater flexibility of the battery holder 214, which was already helpful when mounting the battery holder 214 on the helmet shell 36, and also a later breakage of the upper holding hooks 218a, 218b, since part of the impact force of the object hitting the helmet shell 36 and the battery holder 214 is initially dissipated as elastic deformation of the battery holder 214, in particular of the upper holding arms 216a, 216b. If the upper holding hooks 218a, 218b are finally broken due to excessive deformation, it is generally guaranteed that the battery holder 214 will completely detach from the helmet shell 36, fall downwards and not just remain partially fixed to the helmet shell 36.
- the recognizable step 223 rests against an edge of the helmet shell 36 in such a way that the ventilation slide 50, which is mounted displaceably relative to the helmet shell 36, can be moved beyond the step 223 in the direction of the edge of the opening in the helmet shell 36.
- This enables the ventilation slide 50 to further close the ventilation openings 53 in the helmet shell 53, through which the upper retaining hooks 218a, 218b reach into the helmet shell 36.
- Figure 17b shows a structure of the ventilation slide 50, on which the LEDs known from Figures 7a to 7c are arranged on both sides of the edge 4004, namely the helicopter LED 4000 and the further helicopter LED 4002a, which have different beam directions due to the edge 4004.
- the beam directions of the two helicopter LEDs 4000 and 4002a shown in Figure 17b can be designed essentially perpendicular to each other in such a way that, for example, the helicopter LED 4000 can function as a "tail light" when the wearer is standing upright, while the further helicopter LED 4002a then shines upwards and is visible from above. If the wearer of the protective helmet 30 bends down, however, the helicopter LED 4000 shines upwards. Additional LEDs, for example with a "side" beam direction, can be provided if required.
- FIG 18 shows a partial detailed view of the helmet shell 36 with the battery holder 214 attached to it and the battery pack 100 inserted.
- the two lower retaining hooks 222a and 222b can be seen in particular, which surround a lower rear edge of the helmet shell 36 and are arranged directly on the frame of the battery holder 214.
- a clamping unit 48 can also be seen below the helmet shell 36, which will be explained in more detail in connection with the carrying basket 42 already mentioned above.
- the connecting cable 24 emerges from the interior of the helmet shell 36, which extends into the battery holder 214 and establishes a connection between the helmet light 10 fixed in the front area of the helmet shell 36 and the battery pack 100 inserted in the battery holder 214 via the connecting plug 192, which is not individually visible, wherein the battery pack 100 is held by the elastic tab 224 in the frame of the battery holder 214.
- Figure 19 shows a first frontal view of the protective helmet 30 with the helmet light 10 attached to it from the front
- Figure 20 shows a second frontal view of the protective helmet 30 with the helmet light 10 attached to it from the front
- Figure 21 shows a third frontal view of the protective helmet 30 with the helmet light 10 attached to it from the front.
- the helmet light 10 is shown in its assembled state, so that on the one hand the forward-facing lens unit 14 of the helmet light 10 can be seen and furthermore the front retaining hooks 112 and 114 engaging in the notch/groove 58 are visible.
- the protective helmet 30 shown also comprises the face protection 32 which is pivotably fixed relative to the helmet shell 36 and which can be formed in particular from an open metal grid with a frame stiffening the metal grid in order to protect the face of a user 26 wearing the protective helmet 30 when it is bent downwards. protect.
- a different choice of material, for example Plexiglas or a plastic grid, is also conceivable and can be provided as required.
- the protective function for the user 26 is particularly evident from Figure 20, in which the face protection 32 is directed downwards relative to the helmet shell 36 of the protective helmet 30 and is located in the line of sight between the user 26 and the viewer.
- the face protection 32 as in Figure 19, is directed upwards relative to the helmet shell 36 of the protective helmet 30.
- the protective goggles 130 which are also provided are directed downwards so that, like the face protection 32 in Figure 20, they are located in the line of sight between the user 26 of the protective helmet 30 and the viewer.
- the task of the protective goggles 130 is of course in particular to protect the eyes of the user 26, be it from dust and dirt.
- a material selection of the protective goggles 130 adapted to the visual performance of the user 26 can also be provided.
- the protective goggles 130 which are also pivotably mounted relative to the helmet shell 36, can take on the role of a visual aid in the sense of glasses for the user 26.
- FIG 22 shows a detailed view of a protective helmet 30 with a helmet light 10 attached to it, viewed diagonally from above.
- the protective helmet 30 is shown with the face shield 32 facing upwards opposite the helmet shell 36, whereby from this perspective the front edge 56 of the helmet shell 36 remains visible, even if the notch/groove 58 previously visible in Figure 21 is located below the helmet shell 36 from the viewer, and the face shield 32 is also located between the helmet light 10 and the viewer from this perspective. Accordingly, the helmet light 10, just like the face of the user 26 of the protective helmet 30, is protected from mechanical influences from outside by the face shield 32.
- the protective helmet 30 which is designed in particular for use in forestry, is shown with different features in Figures 23a and 23b in a side view and in Fig. 24 in an exploded view and partly in section.
- an inside of the helmet shell 36 is particularly visible.
- the protective helmet 30 comprises the face protection 32 and hearing protection 34.
- the protective helmet 30 also comprises the helmet shell 36 and an interior fitting assembly 40, which comprises the carrying basket 42, a headband 44 and a neckband 46.
- the neckband 46 is equipped with the tensioning unit 48.
- the helmet shell 36 is provided on the outside with the ventilation Slider 50 with which openings 52 formed in the helmet shell 36 can be opened and closed.
- Three support arms designed as spacers serve as a means for a three-point fastening of the interior fittings or interior fitting assembly 40 to the helmet shell 36, whereby only two support arms 54 are visible in Figure 24.
- the support arm 54 running in the longitudinal direction of the helmet shell 36 to the helmet shell 36, the latter is provided with a slot in the back of the head area, in which the correspondingly shaped free end of the support arm 54 pointing in the longitudinal direction can detachably snap into place on the helmet shell 36.
- the helmet shell 36 and the support arms 54 are dimensioned and arranged (i.e., their clear width is so long and so wide) that there is a free space between the interior fitting assembly 40 and the helmet shell 36 to accommodate the helmet light 10, the associated wiring, ear muffs 35a of the ear protector 34 and other helmet accessories as well as fastening devices for at least the face shield 32 and the ear protector 34.
- the other helmet accessories include the previously mentioned tensioning unit 48 of the neck strap 46.
- the helmet shell 36 is designed as a one-piece plastic molded part.
- a suitable plastic for the helmet shell 36 is, for example, ABS.
- the helmet shell 36 is pulled forward so far that it also serves as a shield above the eyes of the user 26.
- the helmet shell 36 therefore has a uniformly rising outer surface in its front area towards the rear without any significant gradation, so that it offers no hooking points for obstacles such as branches.
- the transverse reinforcing ribs 62 are formed on the inner surface of the helmet shell 36 in the front and middle helmet area.
- a further reinforcing rib extending in the longitudinal direction of the protective helmet 30 can be formed transversely to the reinforcing ribs 62 and in the middle. In the middle area of the helmet shell 36, the reinforcing ribs 62 adjoin a slightly inwardly recessed area which has openings 52 in pairs.
- the ventilation slide 50 is arranged so that it can be moved on the outer surface of the helmet shell 36, which has retaining knobs projecting downwards and inwards in two front guide slots on the helmet shell 36 and with two further retaining knobs in two rear guide slots on the helmet shell 36.
- the ventilation slide 50 comprises the ventilation openings 53 (Fig. 24) which are arranged congruently with the openings 52 and which are located above the openings 52 in the ventilation position and are offset in the closed position so that the openings 52 are closed by the ventilation slide 50.
- the lower edge of the protective helmet 30 is pulled downwards at the sides in the area of the temples and at the sides in the area of the back of the head.
- three rod-like projections 74b are formed on the inside of the helmet shell 36 on each side, to which the interior fitting assembly 40 can be fastened in a form-fitting and detachable manner with the lateral support arms 54.
- the rod-like projections 74b can be seen in the sectional view of the helmet shell 36 in Fig. 24.
- the rod-like projections 74b are each hollow profile parts with a square cross section, which are formed with a foot area on the inside of the helmet shell 36. In their area opposite the foot area, the rod-like projections 74b are arranged standing freely in front of the inner surface of the helmet shell 36.
- connection of the rod-like projections 74b to the inside of the helmet shell 36 and their transition to the helmet shell 36 in the area adjacent to the connection point in a triangular gusset is stiffened by additional molded ribs between the rod-like projections 74b and the helmet shell 36, so that the rod-like projections 74b are essentially rigidly connected to the helmet shell 36. If a force is exerted on the rod-like projections 74b transversely to their longitudinal direction, which tends to bend the rod-like projections 74b, the rod-like projections 74b tend to deform the helmet shell 36 accordingly.
- a hearing protection fastening device 80 for the hearing protection 34 has two hearing protection bearing points 80a on the inside of the helmet shell 36.
- the hearing protection bearing points 80a are pivot bearings which are molded onto the inside of the helmet shell 36 or, preferably, are permanently attached as additional parts.
- Support brackets 37a with the respective hearing protection capsules 35a are pivotally mounted in the hearing protection bearing points 80a.
- a face protection fastening device 84 for the face protection 32 has two face protection bearing points 84a on the inside of the helmet shell 36. Holding arms 132a of a visor 132 are pivotally mounted in the face protection bearing points 84a.
- the face protection bearing points 84a are not formed on the inside of the helmet shell 36, but rather on a plug 136a, which are plugged onto the rod-like projections 74b in order to simultaneously fix the free ends of the support arms 54 on the rod-like projections 74b.
- the face protection bearing points 84a are located with their associated plugs 136a in the assembled state in the free space, namely in an area in which the helmet shell 36 is pulled downwards at its lower edge, as already explained above.
- the interior assembly 40 is the part of the protective helmet 30 that contacts the head of the user 26 and consists of the carrying basket 42, the headband 44 and the neckband 46, which is equipped with the tensioning unit 48.
- the interior assembly 40 can be fixed to the helmet shell 36 by means of the support arms 54 in order to support and hold the protective helmet 30 on the head of a user 26.
- the carrying basket 42 is formed from a rigid, elastically flexible material, preferably from a plastic such as polyamide.
- the carrying basket 42 is provided in two temple areas and in a back of the head area with a rigid support arm 54 that projects diagonally downwards or backwards, which together serve to provide a three-point attachment of the interior fittings assembly 40 to the helmet shell 36.
- This arrangement enables the free space in the helmet shell 36 that extends continuously around the interior fittings assembly 40, which in turn serves to accommodate ear protection capsules 35a, helmet light 10 and other helmet accessories as well as fastening devices 80, 84 for the face and ear protection 32 and 34, respectively.
- the carrying basket 42 is manufactured as a one-piece plastic molded part in the embodiment described here.
- the support basket 42 can be formed from two pairs of mutually spaced support strips which cross in the middle and whose lower ends merge into a single, circumferentially closed support strip at four connection points.
- a particularly A cross-shaped piece of padding material should be provided which rests on the support strips in order to increase wearing comfort.
- the support arms 54 can project out from the support basket 42, in particular at the connection points.
- the headband 44 is molded onto the support basket 42.
- the neckband 46 has two front ends that are detachably connected to rear free ends of the headband 44, for example by a snap connection (not shown in detail). As shown in Figs. 23a and 24, the neckband 46 has two free ends that can be detachably connected to one another in the neck area, using the tensioning unit 48.
- the neckband 46 can be made of the same material as the support basket 42.
- the neckband 46 is connected to the support basket 42 in a height-adjustable manner between its connections to the headband 44 and its free ends.
- the support basket 42 has two support arms that protrude downwards, to which the neckband 46 can be fixed at a selectable height.
- the neck strap 46 has three holes arranged one above the other on each side, which can be snapped into place on a spring-loaded bolt 49 protruding from each support arm.
- the support arms 54 are attached to the helmet shell 36 in different ways, but this is not absolutely necessary.
- the support arms 54 can all be attached to the helmet shell 36 in the same way. To do this, the different attachment means only need to be standardized.
- the rearwardly projecting support arm 54 is pushed into a slot provided for this purpose in the helmet shell 36 until projections provided on this support arm 54 engage on the outside of the helmet shell 36.
- the interior fitting assembly 40 is then moved further inwards towards the inner surface of the helmet shell 36, with the laterally extending support arms 54 being slipped over the rod-like projections 74b.
- Through-openings in the laterally extending support arms 54 receive the rod-like projections 74b in a form-fitting manner.
- the support arms 54 are subjected to a tensile load by the helmet shell 36, which is supported on the ends of the support arms.
- This force acting on the support arms 54 creates a moment at each of the three points that tends to deform the helmet shell 36 inwards to the lower edge.
- the helmet shell 36 thus converts part of the force acting on it into deformation energy and thus reduces the force acting on the person wearing the protective helmet 30.
- the transmission of the moment from the support arms 54 to the helmet shell 36 is further enhanced by the fact that the support arms 54 are additionally stiffened by molded-on ribs.
- the hearing protection 34 comprises hearing protection capsules 35a, each of which is pivotably mounted in a fork-shaped support bracket 37a.
- the helmet shell 36 is provided with the fixed hearing protection bearing points 80a on its inside.
- the hearing protection bearing point 80a is shown together with the support basket 42, but this bearing point is attached to the inside of the helmet shell 36 and not to the support basket 42.
- the illustration in Fig. 24 is merely intended to illustrate where in space the hearing protection bearing point 80a is located in relation to the support basket 42 of the interior fitting assembly 40.
- the support brackets 37a which are provided with the hearing protection capsules 35a, are pivotably mounted in the hearing protection bearing points 80a.
- the hearing protection bearing points 80a and the support brackets 37a are arranged and designed such that the support brackets 37a can be pivoted in the free space between two positions.
- the ear protectors 35a cover the ears of the user 26.
- the ear protectors 35a are stowed in the free space in the helmet shell 36.
- Each support bracket 37a is designed to be spring-loaded and bendable in an area between its two ends, in which it extends into the free space, so that the ear protection capsules 35a are folded away from the ear in the non-bent position of each support bracket 37a and are folded against the ear in the bent position of the support bracket 37a.
- the two ear protection capsules 35a in the latter part each reach a position that is significantly further inward than the ear against which each ear protection capsule 35a is intended to rest.
- the mutual distance between the ear protection capsules is in this case significantly smaller than the mutual distance between the ears.
- each bracket 37a can be moved by hand into a bent and a non-bent position. In each of these positions, the bracket spring 92a causes an end position lock. The end position lock of the bracket 37a is not achieved when the protective helmet is put on because, as mentioned, each ear defender 35a is supposed to be held pressed against the ear by a spring.
- each hearing protection bearing point 80a and each support bracket 37a are designed such that the support brackets 37a can only be pivoted between the operating position and the parking position. This ensures that the hearing protection capsules 35a can be stowed in the free space behind the ear without colliding with the ears and the lower edge of the helmet shell 36.
- Fig. 24 shows the protective helmet 30 in an exploded view and partially in section, where the face shield 32 can be seen in association with other helmet accessories.
- the face shield 32 comprises the visor 132 with two holding arms 32a and two plugs 136a, on each of which the face shield bearing point 84a is formed as a fastening device for the face shield 84.
- the plugs 136a are plugged onto the rod-like projections 74b, whereby the face shield bearing points 84a come to lie in the temple area on the inside of the helmet shell 36.
- the plug 136a with the face shield bearing point 84a can be seen in Fig. 24.
- the oppositely arranged parts of the fastening are not shown.
- Each face shield bearing point 84a has three axially protruding, elastically flexible cams 85a, over which the holding arms 132a with ring bearing bushes can be pushed in order to fasten the holding arms 132a in the face shield bearing points 84a in a detachable and pivotable manner.
- the face shield support points 84a and the support arms 132a are arranged and designed such that each support arm 132a is pivotable in the free space between two positions, an operating position in which the visor 132 is folded down and protects the face (Fig. 20), and a parking position in which the visor 132 is folded up and is arranged in a snug fit on the outer surface of the helmet shell 36 (Figs. 21 and 22).
- the fastening device 84 for the face shield 32 contains a self-locking holder for each support arm 132a.
- for each connector 136a contains a spring-loaded bolt which holds the ring bearing bush 134a attached to the holding arms 132a in a spring-loaded manner in the operating position and in the parking position.
- the visor 132 forms a fork with each holding arm 132a (Fig. 24) in which the wall of the helmet shell 36 is tightly received when the visor is open.
- the visor 132 When the visor 132 is closed, the upper edge of the visor rests on the front edge of the helmet shell 36, and the side edges of the visor 132 rest on the outer surface of the helmet shell 36. Therefore, neither when the visor is closed nor when the visor is open, is there any possibility that branches can hook onto the holding arms 132a or the visor 132 itself when the protective helmet 30 is being used, for example during forestry work, and endanger the user 26.
- the clamping unit 48 is briefly described below.
- the clamping unit 48 is another helmet accessory which, like the hearing protection 34, is always within the outline of the helmet shell 36 so that there are no protruding parts in the area of the clamping unit 48 that could catch on obstacles.
- the two ends of the neck strap 46 are detachably connected in the neck area by the clamping unit 48.
- the clamping unit 48 comprises a holder 168 into which the free ends of the neck strap 46 are inserted on both sides.
- the holder 168 has square knobs that can be brought into engagement with square openings in the neck strap 46. In this way, the length of the neck strap 46 can be roughly adjusted to suit the size of the head.
- the adjustment is conveniently carried out in such a way that the protective helmet 30 can be put on comfortably when the clamping unit 48 is not activated.
- the neck strap 46 is then tightened with the aid of the tensioning unit 48 after the protective helmet 30 has been put on.
- the tensioning unit 48 is actuated by means of a locking flap 174.
- a support shell 172 provided with a piece of padding material 180 is guided towards or away from the back of the head of the user 26.
- the helmet light 10 fixed to the front area of the helmet shell 36.
- the battery holder 214 arranged on the outside of the helmet shell 36 in the rear area is also visible, whereby of the holding elements of the battery holder 214 only the upper holding hook 218a and the lower holding hook 222a are visible.
- the connecting cable 24 is indicated below the helmet shell, which leads from the helmet light 10 to the battery arranged in the battery holder 214. pack 100, which is also not visible.
- the connection cable 24 is not routed along the lower edge of the helmet on the inside of the lower edge of the helmet shell 36, but rather across the helmet shell 36 in the available free space and through an opening in the helmet shell 36 directly to the battery pack 100.
- connection cable 24 running close to the lower edge of the helmet shell 36 could easily interact with objects outside the helmet shell 36 and in particular could be pulled out of the intended position on the battery pack 100 by these without this being intended.
- an adapted length of the connection cable 24 is advantageous and furthermore a special recess/opening can also be provided in the helmet shell 36 through which the connection cable 24 can be routed in order to connect the helmet light 10 to the battery pack 100 in the battery holder 214.
- Figures 25a to 25i each show parts of a graphical user interface for operating a helmet light.
- the individual views/representations of the parts of the graphical user interface can, for example, be displayed on a separate display, which can be wirelessly or wired to the helmet light 10.
- Various views of the graphical user interface are shown as examples, in particular in English and in black and white, although it is of course clear to the viewer that different colors and/or languages can be selected here.
- the display which shows the parts of the graphical user interface, can be part of a smartphone, for example.
- the smartphone can then be coupled to the helmet light via cable.
- the helmet light 10 can be used.
- the smartphone connected to the helmet light 10 via cable can of course also be used as a power source for operating the helmet light 10 and in particular can also supplement or replace the battery pack 100. It is also conceivable that the smartphone is used like a power bank to charge the battery pack 100.

For example, the temperature of the helmet light 10, in particular the temperature of the controller board 18 or of a temperature-sensitive element arranged on the controller board 18, can be displayed. Of course, a corresponding temperature of the controller board 18 or of another part of the helmet light 10 can also be detected by a temperature sensor arranged elsewhere on the helmet light 10 or in the helmet light 10. In this respect, an automatic temperature-controlled shutdown or power reduction of the helmet light 10 is possible in order to prevent damage to it. Furthermore, a temperature of the battery pack 100 can also be detected and displayed.
- the voltage provided by the battery pack 100 and the current provided by the battery pack 100 as well as any charging current can be detected and displayed by sensor elements to be provided accordingly.
- the charge state of the battery pack or several battery packs 100 which are electrically coupled to the helmet light 10 can also be displayed.
- the status overview can also contain information about which of the possible elements of the helmet light 10 and the other elements connected to it are currently active and with which (adjustable) brightness. For example, in Figure 25a, a walk light, a helicopter light and a battery light are shown as 100%, which corresponds to the maximum possible light emission of the respective lighting elements or lighting modes.
- a face light on the other hand, is shown as deactivated, while a work light is shown as partially activated, namely with 80% of the maximum possible light emission.
- the respective status information can be presented either in alphanumeric representation or with the help of different color scales or color intensities or as bar charts. It is also conceivable, for example, that, to improve readability, different status information of the helmet light 10 is displayed alternately, so that less information is shown on the same area, but this can be displayed larger.
- the helmet light 10 can be operated, for example, using a touch-sensitive display, whereby additional information or functions can be activated or called up, for example, by tapping one of the various elements shown in the figures.
- FIGS 25b and 25c some basic information about a helmet light 10 is shown visually within an app that can be installed on a smartphone.
- the app can be used in particular to connect the smartphone to the helmet light 10 via a wireless connection, in particular Bluetooth.
- the helmet light 10 can first be activated via the switch 120. This activation puts the helmet light 10 at least into a standby mode in which, for example, a connection can be established with the smartphone.
- FIG. 25c An initial screen of a user interface of the app in a (not yet) paired state is shown in Figure 25c, while Figure 25b shows the same initial screen in a (successfully) paired state.
- the status of the connection to the helmet light 10 is indicated in the upper area by the hatching that a connection is being established, and this is simultaneously indicated in writing as "Connecting".

- a camera module of the helmet light 10 which is referred to as "PROTOS CAM”
- PROTOS CAM is marked as switched on and can be controlled via the corresponding button.
- the marking is again indicated with the help of the hatching, which can again represent a color contrast or a color change, and can additionally or alternatively be done in writing.
- buttons can change from red to green, which could correspond to an inactive or active state. It is also possible to indicate a change between a disconnected and a connected state by changing colors.
- the full range of functions of the various lighting modes that can be provided by the helmet light 10 can be made visible to the user with the help of one or more demo functions.
- demos can, on the one hand, illustrate the various basic functions of the helmet light 10 to the user in an initial phase and, on the other hand, can be used to check the unrestricted functionality of the lighting modes to be provided, particularly in a later phase of use in which the user has already gained sufficient experience in operating the helmet light 10.
- Figures 25d to 25i also show various operating states of the helmet light 10 visually and/or in written form in the various views of the graphical user interface of the app shown in each case.
- the hatched light cones visible in Figures 25d, 25f and 25h in connection with the stylized user visualize various possible lighting modes of the helmet light 10.
- Figure 25d shows two light cones, the lower one belonging to the walking light and the upper one to the work light.
- Figure 25f shows a light cone for a face light in the upper area of the stylized head of the user and the light cone of the walking light individually in the lower area.
- Figure 25h shows the light cone of a helicopter light. Different light intensities between 0 and 100% can be selected independently or together for the individual lighting modes.
- a short-term “turbo operation" outside the usual working specification of the LED elements 1610 used in the helmet light 10 can also be provided, which can briefly increase the light output of the LED elements 1610 operated in this way.
- This functionality can be selected, for example, by permanently holding down a "Turbo" button shown in the various figures.
- the temperature display for the helmet light 10 can also be visible, whereby a permissible maximum temperature can be set using an associated control element, for example. Above a measured maximum temperature of this kind, a reduction in the power of the helmet light 10 can be provided.
