Abstract

The subject of the invention is a lamp (1) of a car (17), which is located on the side of the car (17) in the area of the last rear pillar. Furthermore, the object of the invention is a car (17) with this lamp (1) and a method of controlling the lamp (1), where the control unit (19) controls the switching on and off of the said lamp (1) based on the received signals.

Description

The technical solution refers to the additional lighting of the car, which improves the visibility of the car or signaling or enables the function of transmitting information to the vehicle operator.

Current state of the art

Cars are normally equipped with lights, and lights are divided in principle into headlights, which illuminate the surroundings of the vehicle even at a great distance, and lamps, which illuminate the immediate surroundings of the car or are used for optical signaling.

In the current state of the art, various types of lamps are often used, especially lamps for signaling a change of direction (placed in front and rear headlight assemblies, possibly also in rear-view mirrors), illumination of license plates, daytime running lights, illuminated radiator grilles, and the like.

In the current state of the art, some lights, for example direction indicator lights, are located in the rear of the car even outside the rear light assembly. As mentioned, they are placed on the exterior mirrors, where they are recognizable from the other direction and increase passive safety. Also known is the location of the direction change lamp in the C-pillar of the body, which forms part of the rear of the car. Such an embodiment is described in the international patent application WO2020181546 A1. However, this location allows only a slight increase in visibility in the direction behind the car and does not provide a fundamental improvement in the recognition of the car compared to known solutions from the state of the art. The disadvantage of this solution is also the location of the lamp in a place prone to impact. Not only is there a risk of damage to the lamp, but the safety of the car crew is also at risk, as the C-pillar is inappropriately shaped. This solution is also inappropriate because of the aesthetic disturbance, when the lamp detracts from the lines of the car. The lamp divides the C-pillar part of the smooth surface of the pillar and the part formed by the lamp.

Another possibility is the use of an additional part placed on the roof part of the car, as described in the German utility model DE202017107760 U1. Here, to increase the visibility of the lamp, crossbars are used, which are equipped with light sources. This solution is unsuitable mainly because of its complicated connection to the power source. Here, too, the car's aerodynamic properties deteriorate.

Another disadvantage of the mentioned solutions lies in the fact that the mentioned lamps utilize only one specific function of the lamp regardless of their location and do not bring any other added value in connection with their location.

It would therefore be advisable to come up with a solution that would eliminate the given disadvantages of the state of the art.

The essence of the invention

The above-mentioned shortcomings are overcome to some extent by a car lamp comprising a light source and an at least partially translucent lamp cover, the lamp being located on the side of the car in the area of the last rear pillar. This location is particularly advantageous as it brings increased safety and better visibility of the car. At the same time, better lighting around the car is enabled. In addition to these advantages, there is also an increased aesthetic value of the vehicle and lower production costs compared to similar state-of-the-art solutions. The rear pillar is the one of the body pillars that is closest to the rear of the car.

- 1 CZ 2022 - 292 A3

It is advantageous that the rear pillar is a C-pillar or a D-pillar. Mainly because the lamp is most advantageously used in sedan, hatchback, station wagon, SUV, liftback, pick-up, MPV or crossover cars.

The stated goal is preferably achieved by a lamp, where the translucent cover of the lamp absorbs from the viewing side at least 40%, preferably at least 60%, of a part of the light with wavelengths that are absorbed by the window frame. The translucent cover of the lamp therefore absorbs light of the same wavelengths as the window frame. The translucent cover absorbs at least 40% of the light intensity of these wavelengths from the viewing side. It preferably absorbs at least 60% of the light intensity of these wavelengths. So the color of the translucent cover optically follows the window frame. This property can be achieved, for example, by adding dye to the translucent cover. The translucent cover is made of plastic, for example PMMA or PC.

It is advantageous to use the fact that the translucent cover of the lamp is designed as a light guide that contains light-balancing elements, whereby the light-balancing elements are made in the translucent cover or on the non-viewable side of the translucent cover and the light source is located and directed to the entrance surface of the translucent cover of the lamp. This version of the lamp is particularly advantageous due to the low production price and small storage space.

Said object is also achieved by an automobile that includes said lamp, wherein the automobile includes a body that includes at least an A-pillar, a B-pillar, and a C-pillar, wherein the automobile further includes windows on the side of the automobile. The windows are equipped with a window frame at their edges, while the upper part of the window frame on both sides of the car is followed by a lamp in the area of the C-pillar or D-pillar. The aforementioned car solves the problems of the state of the art mentioned above. The upper part of the window frame must be understood as the part of the frame that forms the line of the window closest to the roof frame of the car.

Advantageously, the car further includes a control unit, which includes a memory and a computing unit and is adapted to switch the light sources on and off. Controlling the torch using the control unit is particularly advantageous, as it brings the possibility to programmatically control the torch.

It is advantageously used that the control unit is adapted to receive signals and switch on light sources based on the reception of signals, whereby these signals are at least one of the group of signals including information about the change in the position of the turn signal control lever, a signal including information about pressing the hazard lights button, a signal including information from the control unit regarding the acceleration of the car and a signal including information about the acceleration of the car from the sensor, and at least one signal from the group of a signal including information from the door closing and opening sensor, a signal including information about unlocking or locking the car. The control unit is adapted for alternating switching on and off of the light source of one of the lamps based on a signal including information about a change in the position of the turn signal control lever. Further, the control unit is adapted to alternately switch on and off the light source of both lamps after receiving a signal including information about pressing the warning light button, a signal including information from the control unit regarding the acceleration of the car or a signal including information about the acceleration of the car. Furthermore, the control unit is adapted to switch on the light source of both lamps on the basis of receiving a signal including information about the car being unlocked or on the basis of a signal including information about opening the door. Furthermore, the control unit is adapted to turn off the light source of both lamps based on receiving a signal including information about the car being locked or based on a signal including information about closing the door. The control unit is adapted for optional supply of electrical energy to the light source. A computer program is stored in the memory of the control unit, which includes an algorithm that decides whether the conditions for switching on and off the light sources are met, or which of the light sources is switched on or at what wavelength the light should be emitted.

The problems of the state of the art are further removed by the method of controlling the car lamp, where the control unit switches the light source based on the input. Inputs include any of the following signals:

- 2 CZ 2022 - 292 A3 signal including information about a change in the position of the turn signal control lever, a signal including information about pressing the warning light button, a signal including information from the control unit regarding the acceleration of the car or a signal including information about the acceleration of the car from the sensor, a signal including information from the door closing and opening sensor, a signal including information about the car being unlocked or locked.

Said signals are transmitted to the control unit via the car's bus, for example via conductive cables, optical cables or a wireless connection. The signals themselves are preferably data that the control unit can evaluate and interpret, for example interpreting the sender of the signal and the state or change of state, or a directly measured physical value.

Wherein the method necessarily includes at least one signal from the group; a signal including information about a change in the position of the turn signal control lever, a signal including information about pressing the hazard lights button, a signal including information from the control unit regarding the acceleration of the car, or a signal including information about the acceleration of the car from the sensor. And further, the method necessarily includes at least one signal from the group; a signal including information from the door closing and opening sensor and a signal including information about the car being unlocked or locked.

On the basis of a signal including information about the change in the position of the turn signal control lever, the control unit alternately switches on and off the light source of one of the lamps, emitting light from the range of wavelengths in the interval 580 to 635 nm, i.e. in orange color, or in the range of wavelengths in interval 615 to 750 nm, i.e. in red. It can be seen that the control levers enable the choice of which lamp, i.e. which light sources of the given lamp, are to be alternately switched on and off by the control unit. Simultaneously with them, the light sources of other lamps for indicating a change of direction in the car are alternately switched on and off, which can be located in the rear light assembly, the front headlight, in the side mirrors, etc.

Based on a signal including information about pressing the warning light button, a signal including information from the control unit regarding the acceleration of the car, or a signal including information about the acceleration of the car from the sensor, the light sources of both lamps are alternately turned on and off by the control unit, emitting light from a range of wavelengths in the interval 580 to 635 nm or in the range of wavelengths in the interval 615 to 750 nm. In this case, the light sources of both lamps are alternately switched on and off as a warning sign to other drivers indicating an obstacle. The signal including information from the control unit regarding the acceleration of the car or the signal including information about the acceleration of the car from the sensor can be used, for example, under the restrictive conditions of driving on expressways in the event of sudden braking. For example, only at speeds above 70 km-h ^-1 or 100 km-h ^-1 and with negative acceleration (deceleration) values above 3 ms ^-2 or values above 4 ms ^-2 .

On the basis of a signal including information about the car being unlocked or on the basis of a signal including information about door opening, the light sources of both lamps are switched on by the control unit, emitting light from a substantial part of the wavelength range of 390 to 760 nm, i.e. white light, and based on the signal including information about locking the car or based on a signal including information about closing the doors, the control unit turns off the light sources of both lamps or the control unit turns off the light sources of both lamps after a predefined time period, which is stored in the memory of the control unit. The mentioned range can be full or mentioned or slightly narrowed, for example, the light source can emit radiation in the range of 400 nm to 760 nm, 390 nm to 740 nm or 400 nm to 740 nm, the essential thing is that the rejected light acts as white light.

- 3 CZ 2022 - 292 A3

It is advantageous to use a method where the control unit, under the condition of receiving a signal including information about the car moving backwards or a signal including information about engaging a reverse gear or a signal including information about selecting a reverse gear, the control unit switches on the light source of at least one of the lamps. This achieves a significant increase in the visibility of the car when the driver performs or is about to perform a non-standard movement (backing up). In addition, the driver is provided with additional lighting in places where state-of-the-art cars do not provide lighting. Better lighting results in a lower risk of collision with objects around the car, when there are often objects in garages, parking garages or on the street that stick out in the direction of the car's planned travel. The increased lighting also provides a better representation of images from rear parking cameras, if the car is equipped with them. If the conditions are not met, i.e. for example the car is no longer in reverse or is no longer going backwards, the control unit switches off the light sources.

Advantageously, it can be used that the control unit, under the condition of accepting the condition of receiving a signal including information about the car moving backwards or a signal including information about engaging a reverse gear or a signal including information about selecting a reverse gear and at the same time receiving a signal including information about turning the wheels in the direction of a positive moment relative to vector pointing vertically upwards relative to the floor of the car or a signal including information about turning the steering wheel counterclockwise, the control unit switches on the light source on the left side of the car. Furthermore, the control unit under the condition of receiving a signal including information about the backward movement of the car or a signal including information about the inclusion of a reverse gear or a signal including information about selecting reverse gear and at the same time the condition of receiving a signal including information about turning the wheels in the direction of a negative moment with respect to a vector pointing perpendicularly upwards with respect to to the floor of the car or a signal including information about turning the steering wheel clockwise turns on the light source on the right side of the car. This arrangement allows for a reduction in emissions and possibly electricity consumption, as lighting is only provided on the side of the car where it is needed. Another advantage of this solution is that other road users, even pedestrians, are informed by the lighting in which direction the car will go, which significantly reduces the risk of a collision. If the conditions are not met, i.e. for example the car is no longer in reverse or is no longer going backwards, the control unit switches off the light sources.

Advantageously, the car further includes proximity sensors, whereby the proximity sensors sense the surroundings of the car and transmit information about the surroundings of the car, when the boundary distances are stored in the memory of the control unit, and if the control unit receives a signal from the proximity sensor, that in the distance smaller than the limit distance finds an object, so the control unit switches on the light source on the side of the car where the object was detected at a distance smaller than the limit distance. This function makes it possible to convey an additional visual impression to the driver who is approaching the car and, for example, due to inattention, missed it when turning or changing direction. This function can also be used with great advantage in a locked car that is, for example, parked. In this case, a signal similar to the signals of parking sensors can be transmitted to the driver of an approaching car. This makes it possible to reduce the risk of damage to the car. The mentioned border distance can be, for example, in the range of 0.5 to 2 meters. Advantageously, the limit distance can be different for a car in operation and a parked (locked car with the drive unit switched off or so-called sleeping) car. For example, it might be 2 meters for a car in traffic, while it might be 0.5 meters for a parked car. Advantageously, also with a parked car, the control unit can gradually increase and decrease the light intensity at the light source, which varies proportionally to the distance to the object, or alternately switch the light source on and off with a changing frequency of switching on and off proportionally to the distance to the object. If the object is no longer in the border distance, the control unit switches off the light sources. Proximity sensors can be arranged in such a way that each of them detects only one side of the car (left or right). The sides are designated as left and right, with the boundary being the vertical plane passing through the center of the car and the center distance between the car's wheels. Alternatively, some proximity sensors can sense the surroundings of the car on both sides

- 4 CZ 2022 - 292 A3 of a car, while the control unit or computing unit connected to the proximity sensor determines according to the coordinate system of the car and the distance of the object, whether it is located on the right or left side of the car.

In order to avoid false signaling, it is advantageous before switching on the light source based on the signal from the proximity sensor on the side of the car, where an object has been detected at a distance smaller than the limit distance, by the control unit that the condition is fulfilled that the distance of the object from the car decreases to a predefined the time that is measured from the moment when the control unit received a signal from the proximity sensor that an object is detected at a distance corresponding to the border distance. This reduces the risk of the lamp starting for false reasons, or due to a stationary object in the vicinity of the car. The mentioned time can be a period of time in the range of 0.1 s to 1 s. If the object is no longer in the border distance area, then the control unit turns off the light sources.

Advantageously, the car further includes proximity sensors, wherein the proximity sensors sense the surroundings of the car and transmit information about the surroundings of the car, wherein the proximity sensors sense the surroundings of the car at a distance of 0 m to 4 m from the side of the car. The distance 0 m to 4 m is chosen because it is the extent of one traffic lane. The scanned range in front of and behind the car is stored in the memory of the control unit, and if there is an object in the defined area, the light source of the lamp on the side of the car where the object was detected will be switched on. Said range in front of and behind the car may start behind the car at an interval of 0.5 m to 5 m measured from the rear of the car backwards and 1 m to 3 m in front of the car, measured from the front of the car forward. The mentioned lighting makes it possible to increase the safety and visibility of the car while ensuring that there is no increased consumption of fuel or energy by permanently lighting the lamp. In this way, traffic safety is fundamentally increased, as the appropriate placement of the lamp and the light emitted from the lamp reduces the likelihood of the car being overlooked by other road users. Other participants, especially when changing lanes, can very easily miss a car driving approximately simultaneously due to inattention, poor visibility from the car, or glare from the lights coming from the on-board computer or navigation system and the subsequent slow accommodation of the pupil.

Alternatively, it can be advantageously used that the car further includes a camera sensing the surroundings of the car and a machine vision system which is adapted to recognize vehicles and/or draft animals, where the sensed range in front of and behind the car is stored in the memory of the control unit, while if the car is in the vicinity at a distance of 0 m to 4 m from the side of the car, a vehicle and/or towing animal is detected by the machine vision system in a defined area, the light source of the lamp on the side on which the vehicle and/or towing animal was detected will be switched on. Said range in front of and behind the car may start behind the car at an interval of 0.5 m to 5 m measured from the rear of the car backwards and 1 m to 3 m in front of the car, measured from the front of the car forward. The mentioned lighting makes it possible to increase the safety and visibility of the car while ensuring that there is no increased consumption of fuel or energy by permanently lighting the lamp. In this way, traffic safety is fundamentally increased, as the appropriate placement of the lamp and the light emitted from the lamp reduces the likelihood of the car being overlooked by other road users. Other participants, especially when changing lanes, can very easily miss a car driving approximately simultaneously due to inattention, poor visibility from the vehicle, or glare from the lights coming from the on-board computer or navigation system and the subsequent slow accommodation of the pupil. The advantage of the camera and the machine vision system, which can analyze the objects captured by the camera, is the reduction of false positive identification of traffic participants during simultaneous driving (for example, trees or flying or running birds are not mistaken for a traffic participant to such an extent).

Examples of implementation of the invention

The invention will be further explained by examples of implementation with reference to the respective drawings. The car 17 and the lamp 1 are shown in Figures 1 and 2 in two different body designs of the car 17. The car 17 and its general characteristics are known to the expert from the state of the art, for the purpose of comprehensibility of the invention, only the parts that have a connection with the invention will be further described.

Figure 1 shows the upper part of the car body 17 with the lamp 1 according to the invention, where the car 17 is made in a hatchback body variant, and the car body 17 has three pillars on each side, A-pillar, B-pillar and C-pillar 2. The car door 17 on the side is provided with windows 7, which are provided with a window frame 4, which surrounds the window 7. On the upper part of the car 17, the edge 5 of the roof, which is attached to the roof part of the car body 17, connects to the pillars. The lamp 1 is placed in such a way that it connects to the upper part of the frame 4 of the window in the area of the Pillar 2. It can be seen from the picture that the lamp 1 advantageously extends across the entire width of the C-pillar 2 to the area of the fifth door of the car 17, or to the edge of the spoiler 6. The lamp 1 connects with its upper edge to the edge 5 of the roof and can therefore be attached both to the C-pillar 2 and to the edge 5 of the roof, or to both parts. In addition to improving the visual impression, the elevated position of the lamp 1 also provides a favorable height for light signaling and ambient lighting. On the other hand, the lamp 1 and the car 17 are made identically.

Figure 2 shows a car 17 with a lamp 1 according to the invention, where the car is made in a station wagon body variant, and the car body has four pillars on each side, A-pillar, B-pillar, C-pillar 2 and D-pillar 3. In this embodiment, the car 17 also includes a window 7 outside the door area. This window 7 is also provided with a window frame 4, which surrounds the window 7. On the upper part of the car, the edge 5 of the roof, which is attached to the roof part of the car body 17, connects to the pillars. The lamp 1 is located so that it connects to the upper part of the window frame 4 of the last window 7 in the area of the D-pillar 3. It can be seen from the figure that lamp 1 advantageously extends across the entire width of D-pillar 3 to the area of the fifth door of the car 17, or to the edge of the spoiler 6. Lamp 1 connects with its upper edge to the edge 5 of the roof and can therefore be attached both to D-pillar 3 and to the edge 5 roofs, possibly for both parts. In addition to improving the visual impression, the elevated position of the lamp 1 also provides a favorable height for light signaling and ambient lighting. On the other hand, the lamp 1 and the car 17 are made identically.

The lamp 1 is therefore located on the side of the car 17 in the area of the last rear pillar, where this last pillar is preferably a C-pillar 2 or a D-pillar 3. The lamp 1 includes at least one light source 10 and an at least partially translucent cover 8 of the lamp 1. Translucent the cover 8 of the lamp 1 is translucent from the visible side, i.e. the side that is visible from the outside.

The light source 10 is preferably an LED diode, an OLED diode or a PLED diode, whereby the light source 10 is adapted to selectively emit light at least in a substantial part of the wavelength range of 390 to 760 nm (white light) and to emit light in the interval range of 580 to 635 nm ( orange

- 7 CZ 2022 - 292 A3 light) or to emit light in the range of 615 to 750 nm (red light). It is possible to further use the light source 10, which is adapted to emit light in other arbitrary ranges of the visible spectrum.

The lamp 1 can also include, depending on the arrangement, an internal light guide 11, a seal 12, a fastening element, a printed circuit board 13 on which the light sources 10 are attached or an opaque colored cover 16. Above these elements, the lamp 1 can also include other optical elements such as primary and secondary optical elements, collimators and the like. Individual exemplary embodiments of specific arrangements of the lamp 1 itself are explained below with the help of drawings.

The first exemplary structural arrangement of the lamp 1 is shown in Figures 7a to 7c. In this embodiment, the lamp 1 is adapted to be inserted and fixed in a groove in the column, or in a groove that is formed on one side by the wall belonging to the column and on the other side by the wall that is part of the edge 5 of the roof. The lamp 1 includes a translucent cover 8, which includes three walls, where at least the viewing wall is translucent.

The viewing wall of the translucent cover 8 is preferably made of plastic, for example PMMA or PC. Preferably, the material is provided with a dye at least in the area of the viewing wall, where the admixture of the dye ensures that the viewing wall of the translucent cover 8 in this area absorbs at least 40%, preferably at least 60%, of a part of the light with wavelengths that the frame 4 of the window 7 absorbs. It thus absorbs the same part of the light spectrum as the frame 4 of the window 7 and visually forms a connecting line. The translucent cover 8 is provided with latches 9 on the two walls that follow the viewing wall and are preferably perpendicular to it. The latches 9 are designed to fit into the holes in the groove. The lamp 1 is fixed in the groove so that the viewing wall of the translucent cover 8 is aligned with the post. In order to fill any gap between the translucent cover 8 and the post and to ensure water tightness, in this embodiment the lamp 1 is further equipped with a seal 12, which fills the space between the edge of the groove and the translucent cover 8. Along the length of the lamp 1, it is behind the translucent cover 8 in a substantial part of the length of the lamp 1 an internal light guide 11 is placed, which is equipped with light-releasing elements 15. The light-releasing elements 15 can be scratches on the surface of the inner light guide 11, a microstructure 14 on its surface, or protrusions that allow light to be released towards the visible wall of the translucent cover 8. The light sources 10 are in in this arrangement, they are located at both ends of the inner light guide 11 and emit light towards its entrance surfaces (ends). Preferably, the light sources 10 are LED, OLED or PLED diodes, which are placed on the printed circuit board 13. Advantageously, the lamp 1 can also be provided with a case (not shown) which closes the space of the lamp 1. Said case can be made of a solid material such as plastic, or a flexible material such as rubber.

In the second structural arrangement of the lamp 1, an exemplary structural arrangement of the lamp 1 is shown in Figures 8a to 8c. In this embodiment, the lamp 1 is adapted to be inserted and fixed in a groove in the column, or in a groove that is formed on one side by the wall belonging to the column and on the other side by the wall that is part of the edge 5 of the roof. The lamp 1 includes a translucent cover 8, which includes three walls, where at least the viewing wall is translucent. The translucent cover 8 is provided with latches 9 on the two walls that follow the viewing wall and are preferably perpendicular to it. The latches 9 are designed to fit into the holes in the groove. The lamp 1 is fixed in the groove so that the viewing wall of the translucent cover 8 is aligned with the post. In order to fill any gap between the translucent cover 8 and the post and to ensure water tightness, in this embodiment the lamp 1 is further equipped with a seal 12, which fills the space between the edge of the groove and the translucent cover 8. Along the length of the lamp 1, it is behind the translucent cover 8 in a substantial part of the length of the lamp 1 an internal light guide 11 is placed, which is equipped with light-releasing elements 15. The light-releasing elements 15 can be scratches on the surface of the inner light guide 11, a microstructure 14 on its surface, or protrusions that allow light to be released towards the visible wall of the translucent cover 8. Between the visible wall of the translucent cover 8 and the inner light guide 11, a colored cover 16 is placed, which is located along a substantial part of the length of the lamp 1, and on the upper and lower sides there is a gap between the side walls of the translucent cover 8 and the colored cover 16, which allows the passage of light. The colored cover 16 absorbs the same part of the spectrum of light with the same wavelengths as the frame 4 of the window 7. The colored cover 16 thus ensures an identical visual line passing between the frame

- 8 CZ 2022 - 292 A3 windows 7_a lamp 1. In this arrangement, the light sources 10 are located at both ends of the inner light guide 11 and emit light towards its entrance surfaces (ends). Preferably, the light sources 10 are LED, OLED or PLED diodes, which are placed on the printed circuit board 13. Advantageously, the lamp 1 can also be provided with a case (not shown) which closes the space of the lamp 1. Said case can be made of a solid material such as plastic, or a flexible material such as rubber.

A third exemplary construction arrangement of the lamp 1 is shown in Figures 9a to 9c. In this embodiment, the lamp 1 is adapted to be inserted and fixed in a groove in the column, or in a groove that is formed on one side by the wall belonging to the column and on the other side by the wall that is part of the edge 5 of the roof. The lamp 1 includes a translucent cover 8, which is also a light guide. The translucent cover 8 is preferably made of plastic, for example PMMA or PC. Preferably, the material of the translucent cover 8 is provided with a dye, where the admixture of the dye ensures that the translucent cover 8 absorbs at least 40%, preferably at least 60%, of a part of the light with wavelengths that are absorbed by the frame 4 of the window 7. It therefore absorbs the same part of the light spectrum as frame 4 of window 7 and visually forms a continuous line. On the sides that connect to the viewing wall and are preferably perpendicular to it, the translucent cover 8 is provided with latches 9. The latches 9 are designed to fit into the holes in the groove. The lamp 1 is fixed in the groove so that the viewing wall of the translucent cover 8 is aligned with the column. In order to fill any gap between the translucent cover 8 and the post and to ensure waterproofness, in this embodiment the lamp 1 is further equipped with a seal 12, which fills the space between the edge of the groove and the translucent cover 8. The translucent cover 8 is equipped with light-releasing elements 15. The light-releasing elements 15 can be scratches on the surface of the translucent cover 14, the microstructure 14 on its surface, or protrusions that allow light to be emitted towards the visible wall of the translucent cover 8. In this embodiment, the microstructure 14 is used, which is formed by microscopic or macroscopic particles dispersed in the material of the translucent cover 8, alternatively, the microstructure 14 is formed by small spaces filled with air. In this arrangement, the light sources 10 are located at both ends of the translucent cover 14 and emit light towards its entrance surfaces (ends). Preferably, the light sources 10 are LED, OLED or PLED diodes, which are placed on the printed circuit board 13. Advantageously, the lamp 1 can also be provided with a case (not shown) which closes the space of the lamp 1. Said case can be made of a solid material such as plastic, or a flexible material such as rubber.

A fourth exemplary construction arrangement of the lamp 1 is shown in Figures 10a to 10b. In this embodiment, the lamp 1 is adapted to be inserted and fixed in a groove in the column, or in a groove that is formed on one side by the wall belonging to the column and on the other side by the wall that is part of the edge 5 of the roof. The lamp 1 includes a translucent cover 8, which includes three walls, where at least the viewing wall is translucent. The viewing wall of the translucent cover 8 is preferably made of plastic, for example PMMA or PC. Preferably, the material is provided with a dye at least in the area of the viewing wall, where the admixture of the dye ensures that the viewing wall of the translucent cover 8 in this area absorbs at least 40%, preferably at least 60%, of a part of the light with wavelengths that the frame 4 of the window 7 absorbs. It thus absorbs the same part of the light spectrum as the frame 4 of the window 7 and visually forms a connecting line. The translucent cover 8 is provided with latches 9 on the two walls that follow the viewing wall and are preferably perpendicular to it. The latches 9 are designed to fit into the holes in the groove. The lamp 1 is fixed in the groove so that the viewing wall of the translucent cover 8 is aligned with the post. In order to fill any gap between the translucent cover 8 and the post and to ensure water tightness, in this embodiment the lamp 1 is further equipped with a seal 12, which fills the space between the edge of the groove and the translucent cover 8. Along the length of the lamp 1, they are behind the translucent cover 8 in a substantial part of the length of the lamp 1 light sources 10 are located - LED, OLED or PLED diodes, which are located on the printed circuit board 13 and are oriented so that they emit light towards the visible wall of the translucent cover 8. Advantageously, the lamp 1 can also be provided with a case (not shown) that closes lamp compartment 1. The mentioned case can be made of a solid material such as plastic, or a flexible material such as rubber.

A fifth exemplary construction arrangement of the lamp 1 is shown in Figures 11a to 11d. In this embodiment, the lamp 1 is adapted to be inserted and fixed in the groove in the post, or in

- 9 CZ 2022 - 292 A3 groove, which is formed on one side by the wall belonging to the post and on the other side by the wall that is part of the edge 5 of the roof. The lamp 1 includes a translucent cover 8, which includes three walls, where at least the viewing wall is translucent. The viewing wall of the translucent cover 8 is preferably made of plastic, for example PMMA or PC. Preferably, the material is provided with a dye at least in the area of the viewing wall, where the admixture of the dye ensures that the viewing wall of the translucent cover 8 in this area absorbs at least 40%, preferably at least 60%, of a part of the light with wavelengths that the frame 4 of the window 7 absorbs. It thus absorbs the same part of the light spectrum as the frame 4 of the window 7 and visually forms a connecting line. On the two walls that follow the viewing wall and are preferably perpendicular to it, the translucent cover 8 is provided with grooves 26 in the lamp 1, which are terminated by recesses for receiving protrusions 25 that protrude from the side 24 of the groove in the bodywork and protrude from this side . Near the end of the groove 26 in the lamp 1, the groove is narrowed, and this narrowing secures the lamp 1 against further movement at the moment when the protrusions 25 abut on the end of the groove 26 in the lamp 1. The lamp 1 is fixed in the groove so that the viewing wall of the translucent cover 8 was aligned with the post. Along the length of the lamp 1, behind the translucent cover 8 in the essential part of the length of the lamp 1, light sources 10 are located, namely LED, OLED or PLED diodes, which are located on the printed circuit board 13 and are oriented so that they emit light towards the viewing wall of the translucent cover 8. Preferably, the lamp 1 can also be provided with a case (not shown), which closes the space of the lamp 1. Said case can be made of a solid material such as plastic, or a flexible material such as rubber.

In the sixth particularly advantageous embodiment, which is not shown in the figures, the lamp 1 is not provided with a translucent cover 8, but all other parts of the lamp 1 according to the basic arrangement described above in the first, second, fourth or fifth exemplary embodiment are stored in the aforementioned groove. The translucent cover 8 is replaced by the cover of the C-pillar 2 or D-pillar 3, which is made of a metal material or light-impermeable plastic material, and in the area of the lamp 1 it is made of a translucent material. The translucent material is preferably provided with a dye, where the admixture of the dye ensures that the translucent material absorbs at least 40%, preferably at least 60%, of a part of the light with wavelengths that are absorbed by the frame 4 of the window 7. It therefore absorbs the same part of the light spectrum as the frame 4 of the window 7 and visually forms a continuous line. In this design, the need to use the seal 12 is eliminated.

For all exemplary embodiments, it is possible to combine the above-mentioned attachment methods for lamps 1, which can be supplemented with, for example, a screw connection of the lamp 1 and the body or, for example, gluing, i.e. the connection of the lamp 1 and the body using glue.

For controlling, i.e. switching on and off the lamps 1, i.e. the light sources 10 of this lamp 1, the car 17 is equipped with a control unit 19. The control unit 19, for example, instructs the lamp unit 1 to supply electric current to the light sources 10, or controls the supply of electric current directly into 10 light sources. Such a car 17 is shown as an example in figure 12. To ensure some advantageous aspects of the methods of controlling the lamp 1 according to the present invention, the car 17 is also preferably equipped with sensors, such as proximity sensors 22 or door closing and opening sensors 21. Also illustratively shown in the figure is the wireless key 23 of the car 17, which makes it possible to send the unlocking signal of the car 17 to the wireless communication unit 27. The automobile 17 may further include cameras (not shown) that capture the surroundings of the automobile 17, at least in the vicinity of its right and left sides with an overlap forward and backward.

Proximity sensors 22 are sensors that sense the distance between the obstacle and the sensor without physical contact. Proximity sensors 22 usually work on the capacitive principle, the inductive principle, the magnetic principle, the ultrasonic principle or the optical principle, for example a photo detector or a laser detector.

The camera can be an image sensor, for example sensors capable of capturing information together forming an image. Image sensors are, for example, CCD sensors or CMOS sensors.

- 10 CZ 2022 - 292 A3

The door closing and opening sensor 21 is, for example, a capacitive sensor that senses the presence and absence of the door and is located in the door frame.

The control unit 19 includes a memory 20, which consists of a data store and a computing unit, for example a processor. In some embodiments, the control unit 19 may directly integrate the wireless communication unit 27 , in other embodiments, the wireless communication unit 27 may be separate and be communicatively connected to the control unit 19 .

As schematically shown in detail in Figure 13, the individual sensors and units are communicatively connected to at least the control unit 19. The mentioned connection is communication, so it can be a wireless connection based on the principle of a wireless network (WiFi ^TM , ZigBee®, Bluetooth® ^, radio communication and the like), connection by conductive contacts (for example through other elements, buses and necessary hardware) or connection by means of optical data cables.

The method of controlling the lamp 1 of the car 17 is implemented in the first exemplary embodiment of this method in such a way that the control unit 19 switches the light source 10 on the basis of an input, the inputs being signals received by the control unit 19. The signals themselves are preferably data that the control unit 19 can evaluate and interpret, for example interpreting the sender of the signal and the state or change of state, or a directly measured physical value.

Signals is a signal including information about a change in the position of the turn signal control lever, a signal including information about pressing the warning light button, a signal including information from the control unit 19 regarding the acceleration of the car 17 or a signal including information about the acceleration of the car 17 from the sensor, a signal including information from the sensor 21 door closing and opening, signal including information about unlocking or locking the car 17.

On the basis of a signal including information about a change in the position of the turn signal control lever, or another signal to start the turn signals, the control unit 19 alternately switches on and off the light source 10 of one of the lamps 1, emitting light from the range of wavelengths in the range of 580 to 635 nm or in the range of wavelengths in the interval 615 to 750 nm. The control lever makes it possible to transmit as part of the signal to the control unit 19 information about which lamp 1 the control unit 19 should alternately switch on and off. In this case, together with lamp 1, the light sources of the turn signal lamps are alternately switched on and off.

On the basis of a signal including information about pressing the hazard lights button, a signal including information from the control unit 19 regarding the acceleration of the car 17 or a signal including information about the acceleration of the car 17 from the sensor, the control unit 19 alternately switches on and off the light sources 10 of both lamps 1, whereby they emit light from a range of wavelengths in the interval 580 to 635 nm or in a range of wavelengths in the interval 615 to 750 nm. The sensor that transmits information about the acceleration of the car 17 can be, for example, an accelerometer, a navigation system sensor or a speedometer. The sensor of the navigation system or the speedometer can also include a computing unit that calculates the acceleration of the car 17 from the primary data that the sensor detects. Alternatively, the mentioned sensors send direct (raw) data to the control unit 19, in which the algorithm is adapted to calculate the acceleration of the car 17. in this case, together with lamp 1, the light sources of the turn signal lamps are alternately switched on and off.

In this case, the light sources 10 of both lamps 1 are alternately switched on and off as a warning sign to other drivers indicating an obstacle. A signal including information from the control unit 19 regarding the acceleration of the car 17 or a signal including information about the acceleration of the car 17 from the sensor can be used, for example, under the restrictive conditions of driving on expressways in the event of sudden braking. For example, only at speeds above 70 km-h ^-1 or 100 km-h ^-1 and with negative acceleration (deceleration) values above 3 ms ^-2 or values above 4 ms ^-2 .

The wavelength range options can be stored and permanently set in the control unit 19, or it can be changed by service intervention. In some embodiments, the control unit 19 may be stored in memory

- 11 CZ 2022 - 292 A3 territories, which determine the range of light lengths in which the light source 10, i.e. the lamp 1, should emit light.

As soon as the control unit 19 receives a signal including information about the return of the turn signal lever to the neutral position or the deactivation of the warning light button, it ends the sequence of switching on and off the light sources 10 and the given lamps 1 go out. In the event that the signal including information from the control unit 19 regarding the acceleration of the car 17 or the signal including information about the acceleration of the car 17 from the sensor goes outside the predefined limits, the control unit 19 ends the sequence of switching on and off the light sources 10 and the given lamp 1 goes out . Alternatively, the control unit 19 waits a pre-defined period of time, for example 10 s after receiving a signal that the acceleration of the car 17, or its speed is outside the specified limits, and then ends the sequence of switching on and off the light sources 10 and the given lamp 1 goes out.

On the basis of a signal including information about the unlocking of the car 17 or on the basis of a signal including information about the opening of the door, the control unit 19 switches on the light sources 10 of both of the lamps 1, whereby the light emitted is mainly from the wavelength range of 390 to 760 nm. The signal including information about unlocking the car 17 can be, for example, a signal transmitted by the wireless communication unit 27 after receiving a remote signal from the wireless key 23 of the car 17. The mentioned light function is also known as a welcome light and, among other things, improves the orientation of the user in the surroundings of the car 17.

On the basis of a signal including information about the locking of the car 17 or on the basis of a signal including information about closing the door, the control unit 19 switches off the light sources 10 of both lamps 1 or the control unit 19 switches off the light sources 10 of both lamps 1 after a predefined period of time, which is stored in the memory 20 of the control unit 19. The mentioned time period is, for example, in the interval from 2 s to 75 s from the reception of the signal.

In the second aspect of the invention and also the second exemplary embodiment of the method according to the present invention is the following control method, which can be implemented in combination with the method from the first exemplary embodiment.

In this embodiment, the lamp 1 is used to increase visibility and safety when reversing the car 17, and this function is illuminated using figures 6a to 6d, where the car 17 is schematically depicted when viewed from above. Figure 6a shows the car 17 in a normal state when the lamps 1 are switched off. The control unit 19, under the condition of receiving a signal including information about the backward movement of the car 17 or a signal including information about the engagement of a reverse gear or a signal including information about selecting a reverse gear, turns on the light source 10 of at least one of the lamps 1. Therefore, if the car 17 is driving backwards (for example unbraked car 17 with neutral gear engaged), so the control unit 19 switches on the light sources 10. The control unit 19 can get the signal about the movement of the car 17 back, for example, from position sensors, an accelerometer or from a wheel position sensor and the like. The second type of signal that causes the control unit 19 to turn on the lamp 1 is a signal representing that the car is actively reversing or is ready to reverse. In normal cars, this is represented by engaging reverse gear (common in cars with internal combustion engines) or selecting reverse gear (common in electric cars). Therefore, the control unit 19, upon receiving the signal, turns on the lamp 1, i.e. both lamps 1, as shown in Fig. 6d. In the event that the control unit 19 receives a signal including the information that the car 17 is not going backwards and at the same time that the reverse gear is not engaged or the reverse gear is selected, the control unit 19 turns off the lamps 1.

Advantageously, only one of the lamps 1 can be switched on when reversing. In this embodiment, the control unit 19 also receives a signal representing information about turning the steering wheel or a signal including information about turning the wheels. If the reversing condition, mentioned above, is fulfilled, and at the same time the control unit 19 receives a signal including information about turning the wheels in the direction of a positive moment with respect to a vector pointing perpendicularly upwards with respect to the floor of the car 17 or a signal including information about turning the steering wheel counterclockwise, then the control light source 10 is switched on by unit 19

- 12 CZ 2022 - 292 A3 lamps 1 on the left side of the car 17. This situation is schematically depicted in figure 6c.

Figure 6b schematically shows an analogous situation when the reversing condition mentioned above is fulfilled and at the same time the control unit 19 receives a signal including information about turning the wheels in the direction of a negative moment with respect to a vector pointing perpendicularly upwards with respect to the floor of the car 17 or a signal including information about turning the steering wheel clockwise, so that the light source 10 of the lamp 1 on the right side of the car 17 is switched on by the control unit 19.

The flashlight 1 can also be used in the embodiment of the method of controlling the flashlight 1 according to the present invention for light indication to other traffic participants in order to reduce the risk of collision. In the embodiment shown in Figures 4a and 4b, proximity sensors 22 are used for sensing the surroundings of the car 17.

Proximity sensors 22 sense the surroundings of the car 17 and transmit information about the surroundings of the car 17, when the boundary distances are stored in the memory 20 of the control unit 19. The boundary distance is shown in figure 4a with a dimension and marked with the letter S. The specified boundary distance can be, for example, in the range of 0.5 to 2 meters. Advantageously, the boundary distance can be different for a car 17 in operation and a parked (locked car 17 with the drive unit switched off or so-called sleeping) car 17. For a car 17 in operation it can be, for example, 2 meters, while for a parked car 17 it can be 0.5 meter. The situation where the object (the second car 17) is at the boundary distance is shown in Figure 4a, in this situation the lamp 1 is not lit.

If the control unit 19 receives a signal from the proximity sensor 22, including the information that there is an object at a distance smaller than the border distance, then the control unit 19 switches on the light source 10 on the side of the car 17, where the object was detected at a smaller distance than the boundary distance. This situation is depicted in Figure 4b, where the distance, less than the boundary distance, is indicated by the dimension and the letter s.

As soon as there are no objects in the border distance, the control unit 19 turns off the lamps 1. This can be done, for example, based on the signal of the proximity sensor 22, which includes information about objects in the vicinity of the car 17, and comparing the distance with the border distance.

To ensure the elimination of false reports from the proximity sensor 22, it can be used that before switching on the light source 10 on the side of the car 17 based on the signal from the proximity sensor 22, where an object has been detected at a distance smaller than the border distance, the condition that the distance of the object from the car must be met 17 decreases for a predefined time, which is measured from the moment when the control unit 19 received a signal from the proximity sensor 22 that an object is detected at a distance corresponding to the boundary distance. This reduces the risk of the lamp 1 being triggered for false reasons, possibly due to a stationary object in the vicinity of the car 17. The mentioned time can be a period of time in the range of 0.1 s to 1 s. In the event that the object is no longer within the border distance, then the control unit 19 turns off the light sources 10.

This is advantageously used, for example, with a parked (locked car 17 with the drive unit switched off or so-called sleeping) car 17, when an example of the situation is shown in Figures 3a and 3b. In Figure 3a, the approaching car 17 is at a distance greater than the boundary distance. In Figure 3b, it is already at a distance less than the boundary distance and at the same time it is getting closer. Particularly advantageously, for the parked car 17, which is in sleep mode, proximity sensors 22 are used so that they register objects only periodically in a longer period of time (e.g. every 20 seconds) and at a distance greater than the border distance (e.g. 5 meters), and this in order to save electricity. If they register an object that moves towards the car 17, then the periodicity of the measurement is increased, and when the object is at the border distance, the control unit 19 is woken up and the system works identically to the previous description.

- 13 CZ 2022 - 292 A3

Advantageously, also in the case of a parked car 17, the control unit 19 can gradually increase and decrease the light intensity of the light source 10 in proportion to the distance to the object, or alternately switch the light source 10 on and off with a changing frequency of switching on and off, proportional to the distance to the object. If the object is no longer in the boundary distance, the control unit 19 turns off the light sources 10.

The flashlight 1 can also be used in the embodiment of the method of controlling the flashlight 1 according to the present invention for light indication to other traffic participants in order to reduce the risk of collision. In the embodiment shown in Figures 5a to 5c, proximity sensors 22 are used for sensing the surroundings of the car 17.

Proximity sensors 22 sense the surroundings of the car 17 and transmit information about the surroundings of the car 17, with the proximity sensors 22 sensing the surroundings of the car 17 at a distance of 0 m to 4 m from the side of the car 17. The distance 0 m to 4 m is chosen because it is a range one lane. In the memory 20 of the control unit 19, the sensed range in front of and behind the car 17 is stored, and if there is an object in the defined area, the light source 10 of the lamp 1 on the side of the car 17 where the object was detected is switched on. Said range in front and behind the car 17 may start behind the car 17 at an interval of 0.5 m to 5 m measured from the rear of the car 17 backwards and 1 m to 3 m in front of the car 17 measured from the front of the car 17 forward. In the images, the scanned range is indicated by the dimension and the letter B. The mentioned lighting makes it possible to increase the safety and visibility of the car 17 and at the same time ensure that there is no increased consumption of fuel or energy by permanently lighting the lamp 1.

In this way, traffic safety is fundamentally increased, as the appropriate placement of the lamp 1 and the light emitting from the lamp 1 reduces the likelihood that the car 17 will be overlooked by other road users. Other participants, especially when changing lanes, can very easily miss car 17 driving approximately simultaneously due to inattention, poor visibility from car 17, or glare from the lights coming from the on-board computer or navigation system and the subsequent slow accommodation of the pupil.

Figure 5a shows a car 17 according to the present invention driving in the left lane (top of the figure). Car 17 driving in the right lane is outside the sensing range and lamp 1 is not switched on. In Figure 5b, car 17 in the right lane is already in the sensing range and lamp 1 is switched on. For car 17 in the right lane, the position of the driver's head is also indicated, and the driver's view 18 is indicated by a line, which is the view to which the average driver pays the most attention. The indicated light rays of the emitted light, for example, fall on the driver's pupil by reflection from the glass, the road in front of the driver, or into his peripheral vision and increase his attention. When the cars 17 are in the position shown in Figure 5c, the light from the lamp 1 falls directly on the visual receptors of the driver of the car 17 in the right lane.

Alternatively, it can be advantageously used that the car 17 further includes a camera sensing the surroundings of the car 17 and a machine vision system that is adapted to recognize vehicles and/or draft animals, where the sensed range in front of and behind the car 17 is stored in the memory 20 of the control unit 19. if a vehicle and/or towing animal is detected by the machine vision system in a defined area in the vicinity of the car 17 at a distance from 0 m to 4 m from the side of the car 17, the light source 10 of the lamp 1 on the side on which the vehicle and/or was draft animal recorded. Said range in front and behind the car 17 may start behind the car 17 at an interval of 0.5 m to 5 m measured from the rear of the car 17 backwards and 1 m to 3 m in front of the car 17 measured from the front of the car 17 forward. The mentioned lighting makes it possible to increase the safety and visibility of the car 17 and at the same time ensure that there is no increased consumption of fuel or energy by permanently lighting the lamp 1. In this way, the safety of traffic traffic is fundamentally increased, since the appropriate placement of the lamp 1 and the emission of light from the lamp 1 reduces the probability overlooking the car 17 by other road users. Other participants, especially when changing lanes, can very easily miss due to inattention, poor visibility from the vehicle, or glare from the lights coming from the on-board computer or navigation system and the subsequent slow accommodation of the pupil

- 14 CZ 2022 - 292 A3 car driving approximately simultaneously 17. The advantage of a camera and a machine vision system that can analyze objects captured by the camera is the reduction of false positive identification of traffic participants while driving simultaneously (for example, there is no such degree of confusion of trees or flying, or a running bird as a traffic participant).

Industrial applicability

The lamp device, car and control method described above can be used mainly in passenger cars. After the necessary adjustments, the solution can also be adapted to other means of mobility such as scooters, bicycles, motorbikes, motor boats, motorized surfboards and the like.
