Description

The invention relates to a portable lamp with a lamp housing and at least one lamp arranged in this, which lamp is fixed at the place of use and connectable to a power supply device.

From practice, a number of lights are known, which can be described as portable or portable lights. The portable lights include, for example, flashlights, flashlights, hand lamps, hand lamps or headlamps. These usually have an internal power supply device, such as a battery, an accumulator or the like. These portable lights are easy to transport and carried by a user, for example, along a path for lighting. There are other portable lights that can be flanged, for example, at a corresponding site or by means of a pipe clamp or the like to a mast, a pipe or a wall or a ceiling of a corresponding space can be fastened. Such portable lights are connected after attachment at the site with a corresponding power supply device. However, such portable lights can only be used at the place of use, as usually no easy entrainment by a user is possible.

The invention has for its object to improve a portable / portable lamp according to the preamble of claim 1 to the effect that it is carried by a user, and also at the site with a corresponding power supply device is connected, at the same time the energy consumption during entrainment by a User can be reduced.

This object is solved by the features of patent claim 1.

The invention is characterized in particular by the fact that the luminaire has a particularly rechargeable replacement voltage supply device and a switching device. The replacement voltage supply device is used during the entrainment of the luminaire, wherein a corresponding electrical connection to the voltage supply device at the place of use only takes place there by, for example, the user of the luminaire. Furthermore, the switching device is used in mounting the lamp at the place of use and / or electrical connection of the lamp with the power supply device for switching the lamp to at least one other and especially higher illuminance and / or other light distribution.

That is, during the entrainment of the lamp this has a relatively low illuminance, but sufficient to illuminate the path or the like with appropriate movement of the user. Only at the place of use and after attachment and / or electrical connection is then switched to another and especially higher illuminance, which can also be switched to a different light distribution, for example, to illuminate a larger area.

In a favorable embodiment, the replacement voltage supply device may be formed, for example, as a battery or accumulator. Such are usually easy to recharge and can be arranged in a corresponding number or size within the lamp. The replacement power supply can be charged, for example, at the place of use via the power supply device.

At the site then takes place under the above conditions, a corresponding switching from the replacement power supply to the power supply device. This is usually higher load capacity, so that the lamp can be operated with a different and especially higher illuminance.

For the one or more lamps of the lamp bulbs are preferred, which are adjustable in their illuminance. Simple embodiments of such lamps are semiconductor light-emitting components such as LED, OLED or the like. These can be arranged individually or in groups as light sources. Possibly. These can also be used with different colors.

In order to enable a sufficient illuminance when using the portable lamp, corresponding semiconductor light-emitting components are strip-shaped, sheet-like or the like arranged and in particular in the form of chip-on-board modules. These are easily adjustable in their performance and can also be operated, for example, so that when using the replacement power supply device only some of the bulbs are in use, while all bulbs are used when used with the power supply.

Furthermore, it is possible to dim such bulbs, for example, when used with the replacement power supply, so they have a lower illuminance than in Use with the power supply device.

The lamp can be constructed in different ways and in a simple embodiment, the lamp housing has at least one light exit opening and a releasable fastening device. The corresponding bulbs are assigned to the light exit opening (s), wherein within the light, i. in the luminaire housing, also other light-conducting means, such as reflectors, filters or the like can be arranged.

The releasable fastening device is usually arranged on the lamp housing or at least connectable to this. Such releasable fastening devices can be designed in different ways. Simple and easy to use fasteners are, for example, magnetic or mechanical fasteners. That is, the luminaire housing can be fixed, for example, by means of magnets directly to a corresponding panel, masts or the like. Alternatively or in addition to this magnetic attachment, a mechanical attachment can be made for example by means of pipe clamps or other releasable fastening means.

In order in particular to be able to fasten the luminaire to, for example, pipes or masts of different diameters, the fastening device can have at least two attachment means which can be arranged inclined relative to one another at a particularly variable angle and, if necessary, can be rotated. These are wedge-shaped from one side mounted on pipe or mast and then attached magnetically and / or mechanically, for example by means of a pipe clamp or the like.

After this attachment can be made according to the connection to the power supply device.

There is also the possibility that not directly the lamp has a corresponding fastening device, but this example, in particular in the form of a mounting device is located at the site. Such a mounting device may for example be a mounting plate with holding magnets, with mechanical fastening means or other corresponding means.

A simple way of electrical connection of light and power supply can be seen therein, if a corresponding connection cable is used with plugs. It is also conceivable that the electrical connection is wireless. Such a wireless connection can for example be made inductively. In other words, when the luminaire is fastened to a specific location, a corresponding inductive coupling between the voltage supply device and the corresponding device in the luminaire housing takes place automatically. This automatic connection can then also trigger the corresponding switching device, i. there is the switching to the other, in particular higher illuminance.

As already stated, it is not usually necessary to have a particularly high illuminance on the way to the workplace. This has the further advantage that, for example, the replacement power supply within the lamp is loaded less and has a longer life, i. E. also needs to be recharged less frequently.

Reference has already been made to the corresponding semiconductor light-emitting components which can preferably be used as lighting means. However, it is also possible to use other bulbs. However, some of these have the disadvantage that they are less efficient in the conversion of energy into light or not easily dimmable, see the different illuminance levels.

As soon as an electrical connection to the power supply device has been established, it may also prove advantageous if the electrical supply of the light source from the replacement voltage supply device is interrupted at least as of the production of this electrical connection. That is, in such a case, the lamp is powered solely by the power supply. This applies not only to the lighting, but also to all other devices within the lamp, see for example sensors or the like, which may be arranged in or on the lamp.

In order to enable a simple switching, for example, from the replacement voltage supply device to the voltage supply device in this context, the switching device can have a switching device, by which a switching signal can be generated by fixing the luminaire at the place of use and / or when connecting the luminaire to the voltage supply device, by which at least on the other and in particular higher illuminance is switchable. The corresponding switching device may be formed as a separate component of the lamp. However, the switching device may preferably be part of an already existing driver and control device of the luminaire. The driver device is used, for example, for operating the corresponding light-emitting semiconductor components or other bulbs, see fluorescent tube with ballast or the like.

The corresponding switching device can be designed in different ways. One of the above events must be detectable accordingly to be converted into a switching signal. For example, switching devices are conceivable which have at least one magnetic, inductive, tactile sensor or the like. For example, a magnetic sensor can be used when magnets are used to fix the lamp, see the above-mentioned mounting plate with holding magnets. By the magnetic sensor, these holding magnets are detected and it is done by means of the switching means already mentioned switching to the other illuminance. The sensor can also detect the connection to the voltage supply device, so that when supply from the power supply device ago then the switching device is active. An inductive sensor may also be provided to detect in particular an inductive power supply device, in a wireless electrical connection. In addition, by means of the inductive sensor or the other sensors, a corresponding positioning of the lamp relative to the power supply device or the fastening device can be detected. This means that, for example, the voltage supply device, the mounting device or the like can be detected by the sensor. By such a detection, a predetermined mounting position can be detected at the site by the sensor. If, for example, a corresponding mounting plate is used with holding magnets, the position relative to the holding magnets can be detected by corresponding magnetic sensors of the luminaire and thereby the corresponding mounting position.

There is also the possibility that this predetermined mounting position is determined by contacting and / or intermeshing mounting means of the mounting device and the lamp housing. Such means are, for example, projections on a mounting plate and corresponding recesses in a housing wall of the lamp housing. In addition, directly engage the holding magnets of such a mounting plate in corresponding recesses of the lamp housing. As a result, on the one hand, the assembly is simplified and on the other hand at the same time occupied a corresponding mounting position.

There is also the possibility not only to use a sensor, but to detect by at least two sensors of the switching device, the assembly or predetermined mounting positions and / or attachment to the site and / or electrical connection to the power supply device. That is, only when at least two sensors deliver a corresponding switching signal, switching takes place by means of the switching device. An example would be a sensor that detects, for example, the predetermined mounting position and another sensor that detects the electrical connection to the power supply device. If both emit corresponding switching signals, switching takes place by means of the switching device, i. switching to the other, in particular higher illuminance.

The corresponding portable / portable lamp can also be designed according to explosion-proof, as well as in terms of their installation or electrical connection to the power supply device so that it can be used in hazardous areas. In other words, the luminaire according to the invention can likewise be a transportable Ex luminaire. Furthermore, the lamp and in particular the lamp housing can be made of a corresponding material, such as abrasion-resistant, impact-resistant plastic and not shown in particular ergonomically designed lamp switch can be operated for example by latching slide or the like. These slides are accessible from outside the luminaire housing. It is also conceivable that a corresponding switchover from replacement voltage supply devices to voltage supply devices takes place by manual switching on the luminaire.

In the following advantageous embodiments of the invention will be explained in more detail with reference to the accompanying figures in the drawing.

In this case, these components are LEDs. These are through a mask 17 visible with corresponding openings. The luminaire housing 2 is at a job site 4 attached, in particular to a partially illustrated tube 18 ,

In 2 is the light after 1 shown in a side perspective view. In particular, it can be seen that a voltage supply device 5 by means of a pipe clamp 19 on the pipe 18 is attached and from behind the luminaire housing 2 contacted. Appropriate fastening devices 11 with fasteners 12 for attaching the portable lamp 1 on the pipe 18 are also shown. In this case, the power supply is 5 an inductive power supply, the wirelessly a corresponding power supply for the lamp 1 forms.

In 3 and 4 are cuts through the light 1 to 1 and 2 shown along the corresponding longitudinal axes.

These are centered on the back of the lamp housing 2 arranged and can both mutually changeable in their angle and rotatable to each other or relative to the lamp housing 2 be educated. Every fastener 12 has a corresponding magnet 21 on. Through this, see also 2 , becomes the portable light 1 on the pipe 18 held. The appropriate fasteners 12 can by varying the angle between them to different diameter of the tube 18 be customizable.

Midway between the two fasteners 12 is a switching device 14 represented in the form of a magnetic or tactile switch. This detects an appropriate attachment of the lamp to the pipe 18 , see also 4 , Inside the housing is a driver and control device 15 arranged. This controls, for example, the corresponding bulbs 3 , In the illustrated embodiment, the bulbs are LEDs mounted on a printed circuit board 20 either arranged in a strip or even in rows and columns.
