Definitions
- the invention relates to a rear light for a vehicle according to the type defined in more detail in the preamble of claim 1, a method for operating such a rear light and a vehicle with such a rear light.
- LEDs allow the provision of particularly small, yet bright light sources.
- the resulting design freedom is used by vehicle manufacturers to specifically adapt the visual appearance of vehicles.
- LEDs it is possible to provide not only point-shaped light sources on a vehicle, but also surface-shaped, strip-shaped or matrix-like lighting.
- LEDs are arranged next to each other in certain patterns.
- a large number of individual light sources are therefore required to create such a light.
- LEDs are characterized by a long service life. Nevertheless, it can happen that individual LEDs fail prematurely. In such a case, the optical appearance of the lights is adversely affected by the presence of dark areas. The recognizability of the vehicle in question in the dark can also be impaired.
- DE 202010 004 874 U1 discloses an LED module with passive LEDs.
- the document describes an LED module consisting of several LEDs arranged on a circuit board. Each LED is coupled to a light coupling element of a light guide body in order to radiate light emitted by the LEDs outwards.
- at least one passive LED is provided on the circuit board, which is deactivated in a normal operating mode of the LED module and is activated if at least one of the LEDs fails to act as a replacement.
- the LED module can be operated reliably even if individual LEDs fail.
- the disadvantage is the need to integrate additional LEDs into the LED module.
- EP 1 000 806 B1 discloses a diagnostic system for an LED light in a motor vehicle.
- the LEDs of the LED light can be arranged in a matrix.
- the matrix can have several LED strings connected in parallel, with several LEDs connected in series in one LED string. If a single LED fails, the entire LED string containing the defective LED also fails.
- DE 102022 115 153 A1 discloses a method and system for detecting LED failures in a vehicle lighting system.
- the vehicle lighting system comprises a first and a second lamp. If an LED in one of the two lamps fails, both lamps are deactivated.
- DE 102018201 102 A1 discloses a method and a device for functional testing of a matrix light source arrangement and a headlight therewith. To check the functionality of the light source arrangement, an energy value of one of two light sources of the light source arrangement is recorded and compared with a comparison value.
- DE 102012 003200 B4 discloses a translucent body part of the outer skin of a motor vehicle.
- a functional lighting of the vehicle is designed in two parts, with a first part using a light source integrated in a headlight housing and a second part the backlit translucent body part
- the translucent body part can extend over the entire width of the motor vehicle.
- a lighting system for a vehicle is known from DE 102009 019 752 A1.
- the lighting system comprises a vehicle light with at least two LEDs.
- a control unit is able to detect a failure of one of the LEDs and, depending on this, issue a warning to a vehicle user.
- the present invention is based on the object of specifying an improved rear light for a vehicle and a method for operating it, with the aid of which it is possible to continue operating the rear light even if individual lighting sources fail.
- this object is achieved by a rear light for a vehicle with the features of claim 1 and a method for operating the same with the features of claim 5.
- Advantageous embodiments and further developments as well as a vehicle with such a rear light emerge from the dependent claims.
- a generic rear light for a vehicle comprising a plurality of lighting means arranged next to one another according to a pattern, is further developed according to the invention in that at least one partner lighting means is assigned to each lighting means depending on a mirror symmetry or point symmetry in the pattern, wherein a respective center point of a mirror axis or a mirror point lies in the geometric center of the pattern, and wherein a respective partner lighting means is designed to be switched off if the lighting means to which the partner lighting means is assigned fails, so that the symmetry of the pattern is maintained.
- the rear light according to the invention is based on the idea of deactivating individual lamps in the rear light to emit light, so that the symmetry of the pattern in which the lamps are arranged is maintained. It is therefore not apparent at first glance that individual lamps in the rear light have failed. Accordingly, the The rear light according to the invention continues to operate and does not need to be replaced by a new one.
- the individual light sources are arranged in a two-dimensional field.
- a field can also be referred to as an array or matrix.
- the assignment of lamps to partner lamps is easy.
- the pattern in which the lamps are arranged, i.e. the geometric distribution of the lamps, is known.
- Partner lamps can be found depending on the respective symmetry.
- the respective assignment can then be stored in the form of digital data in a computer-readable storage medium of a processing unit. If at least one lamp fails, a corresponding control unit accesses this data storage to monitor and/or control the lamps and can therefore easily determine which partner lamp must generally be switched off.
- switching off means that if the respective light source fails, the partner light source is no longer controlled to emit light.
- the partner light source therefore remains deactivated at all times.
- the rear light can use the pattern to project static light characteristics or dynamic light characteristics into the surrounding area.
- At least one light source is formed by an LED.
- LEDs can be manufactured with particularly small dimensions and high luminosity, which allows the creation of particularly complex patterns and thus visually appealing rear lights. LEDs are also comparatively inexpensive and are characterized by a long service life. In general, however, the light sources could also be light bulbs, xenon lamps, gas discharge lamps, lasers and the like.
- the rear light has an integrated control unit for monitoring and/or controlling the lamps.
- the individual lamps must be monitored and specifically controlled.
- Both the monitoring and the control function can be integrated in a common control unit.
- the control unit can be part of the vehicle or preferably integrated into the rear light itself. This makes it possible to provide an assembly that is easy to install and put into operation.
- the monitoring and control functionality can also be split into several computer systems or modules.
- the monitoring functionality can be integrated into a computer system of the rear light and a control functionality into a control unit of the vehicle or vice versa.
- both functionalities are particularly preferably provided by a control unit integrated into a respective rear light.
- a respective control unit has a computer-readable storage medium in which the assignment of the lighting devices to respective partner lighting devices is stored.
- a further advantageous embodiment of the rear light according to the invention further provides that the pattern is designed in such a way that for at least one location in the pattern and a corresponding partner location, light with at least two different colors can be emitted by the lamps.
- the location can also be understood as a single pixel of the field or matrix.
- Several differently colored lamps can then be installed in such a pixel, or different colors can be emitted into the environment with one and the same lamp.
- the partner location is determined for the location in the same way as the partner lamps for the respective lamps.
- red, orange and white or red, green and blue Red is typically used by vehicles as a tail light or brake light.
- a direction indicator typically emits orange or yellow light.
- White light can be used to form a reversing light.
- a red, green and blue LED can be provided at a particular location in the pattern, or in each pixel. By specifically controlling the brightness of the respective colored LED, a wide variety of colors can then be created by color addition, in particular red, orange and white.
- a method according to the invention for operating a rear light described above comprises the following method steps:
- monitoring the correct functionality is possible with an internal or external monitoring unit for the respective rear light.
- the monitoring unit can, for example, be part of the control unit or integrated into it.
- the respective partner light source can then be deactivated for both static and dynamic lighting.
- a monitoring module monitors an electrical voltage, an electrical current and/or a resistance of at least part of an electrical circuit of the rear light. If an individual light source of the rear headlight fails, this influences the way in which electrical current flows through the circuits of the rear light. Higher or lower voltages or currents can then flow between individual components. In particular, the resistance of individual components also changes.
- the monitoring module is able to monitor the respective components of the electrical circuit of the rear light and thereby determine the failure of light sources. Depending on which parts of the electrical circuit change their behavior, the monitoring module is able to determine which light source has failed. For example, each light source is integrated into the electrical circuit via an individual circuit. By analyzing which circuit changes its electrical behavior, the failed light source can then be determined.
- the monitoring module can be the monitoring unit mentioned above.
- the monitoring module can therefore be integrated into the control unit or be installed externally.
- the monitoring module can also be part of the rear light or part of the vehicle.
- a vehicle according to the invention has a rear light as described above.
- the rear light included in the vehicle is preferably operated using a method according to the invention.
- the vehicle can be any vehicle such as a car, truck, van, bus, motorcycle or the like.
- the rear light is designed to emit the light characteristics of a tail light, a reversing light, a brake light and/or a direction indicator.
- the rear light is therefore designed to function as a corresponding tail light, reversing light, brake light and/or direction indicator.
- When operated as a tail light moderately bright red light is statically projected into the surroundings.
- When functioning as a brake light the red light projected into the surroundings is projected into the surroundings with a higher brightness when a brake pedal is operated.
- white light is projected into the surroundings after reverse gear is engaged.
- a direction indicator a corresponding orange or yellow flashing light is provided when a turn signal lever in the vehicle is operated.
- An individual rear light can be provided on the vehicle for each function, for example a rear light according to the invention for providing a reversing light and a rear light according to the invention as a brake light.
- the respective rear lights can be provided twice, once for a left half of the vehicle and once for a right half of the vehicle. However, it is particularly preferred to have a rear light in which all functions are integrated.
- the vehicle has a continuous rear light extending horizontally across the rear of the vehicle, wherein the rear light is designed to emit a first light characteristic over at least a first part of the pattern and a light characteristic corresponding to the first light characteristic over a second part of the pattern.
- the first light characteristic can be, for example, the light characteristic of a brake light or a reversing light.
- the first part of the pattern can then be, for example, in the area of the rear of the vehicle in which the left brake lights or reversing lights are otherwise arranged.
- the second part of the pattern can accordingly be in the Area of the rear of the vehicle in which the right brake lights or reversing lights are otherwise arranged.
- the vehicle according to the invention therefore preferably has a rear light according to the invention, via which several light characteristics of different lighting functions can be provided.
- a rear light according to the invention via which several light characteristics of different lighting functions can be provided.
- the left rear and right rear brake light can be provided, but also, for example, a third, additional brake light which, viewed in the direction of the vehicle's transverse axis, is projected into the environment between the first part of the pattern and the second part of the pattern, in particular centrally between the first part of the pattern and the second part of the pattern.
- a further advantageous embodiment of the vehicle according to the invention further provides that a monitoring module for detecting the failure of a light source is set up to cause an alert to be output to a user via vehicle-internal output means after the failure of at least one light source has been detected, wherein in particular the light sources are divided into a first number of light sources and a second number of light sources depending on an arrangement in the pattern and the monitoring module causes a different alert to be output when a light source of the first number fails than when a light source of the second number fails.
- a person driving a vehicle or the vehicle owner typically only checks the correct functioning of their rear lights irregularly or not at all. Accordingly, it can happen that the person in question drives with a defective rear light for a comparatively long time.
- the monitoring module can cause alerts to be output if at least one light source fails, so that the respective user can be made aware of the defect.
- Visual, acoustic and/or haptic alerts can be output via corresponding output means.
- explanatory text messages and/or pictograms can be displayed on a display device in the vehicle, such as the instrument cluster, the head unit, a head-up display or the like.
- Acoustic warning tones can be emitted via loudspeakers, such as the sound of a bell or a siren and/or corresponding text messages can be read out by a computer voice.
- vehicle structures that are frequently touched by a vehicle occupant such as the steering wheel, controls, the vehicle seat, pedals or the like, can be caused to vibrate.
- Corresponding notification messages can also be forwarded to a mobile device linked to the vehicle, such as the user's smartphone.
- the user is simply informed of the general failure of at least one light source.
- the notification message can be designed differently for different light sources. This is particularly the case with a single rear light that extends across the entire width of the rear of the vehicle.
- certain lights In order for a vehicle to be registered, certain lights must be present in certain positions on the vehicle. For example, the brake lights or reversing lights, direction indicators and the like must be in certain positions and enable very specific light characteristics to be projected into the surrounding area. If a light source such as this, which specifically serves the function of the brake light, reversing light, direction indicator or the like, fails, the roadworthiness of the vehicle is adversely affected.
- the notification message can contain a request to visit a workshop in order to repair the damage as quickly as possible. This allows the vehicle to remain roadworthy or to be restored as quickly as possible. If, however, a light source fails that is not used to provide the appropriate light characteristics, it is not necessarily necessary to visit a workshop particularly quickly. Accordingly, the notification message can only contain the information that a light source has failed. In addition, information can also be shown here about which light source has failed. For example, an image of a rear light according to the invention can be shown on a display device in the vehicle, with the failed light source being highlighted.
- Fig. 1 is a schematic view of a rear light according to the invention
- Fig. 2 is a schematic view of the rear of a vehicle according to the invention.
- Fig. 1 shows a rear light 1 according to the invention for a vehicle 2 shown in Fig. 2.
- the rear light 1 comprises a plurality of lighting means 3 arranged according to a pattern 6. To maintain clarity, only some elements are provided with a reference number.
- the lighting means 3 for example LEDs, are arranged in a square to form a field or a matrix. A respective position at which a respective lighting means 3 is arranged can then also be referred to as a pixel.
- Fig. 1 failed lamps 3 are indicated by hatching. Those lamps 3 that have failed are outlined with a thick continuous line.
- a respective lamp 3 is assigned to corresponding partner lamps 3P.
- the pattern 6 in which the lamps 3 are arranged has at least one symmetry property. In Fig. 1, it is a square pattern, whereby there are four mirror axes 4 and one mirror point 5.
- the respective partner lamps 3P of the lamps 3 are indicated by appropriate hatching and a dashed border.
- Fig. 1 shows the case in which exactly one partner lamp 3P is switched off for each lamp 3.
- several partner lamps 3P can be found for each lamp 3, for example a partner lamp 3P for the horizontal mirror axis 4 and the vertical mirror axis 4. It would thus be possible to switch off not just one partner lamp 3P for each lamp 3, but several (not shown).
- Fig. 2 shows the view of the rear of the vehicle 7 of a vehicle 2 according to the invention.
- the rear light 1 is here designed to be horizontal across the rear of the vehicle 7.
- the pattern 6 can preferably be divided into at least a first part 6.1, a second part 6.2 and a third part 6.3.
- the light characteristic emitted by the lamps 3 is preferably designed to be the same in the first part 6.1 and the second part 6.2 of the pattern 6.
- the design of the light characteristic in the third part 6.3 is initially irrelevant. It is thus possible to provide several different functional lights, such as a direction indicator, a brake light, a reversing light and the like in the respective parts 6.1, 6.2, 6.3 via a rear light 1.
- the lamps 3 can shine red evenly across the entire pattern 6. If vehicle 2 brakes, the brightness of the red light in the first part 6.1 and the second part 6.2 can be increased so that a brake light can be output. Optionally, an additional brake light could be displayed in the third part 6.3 of pattern 6.
- the light sources 3 of the rear light 1 can be divided into a first number 8.1 and a second number 8.2. The division is made in particular depending on legal framework conditions. For example, certain functional lights must be provided in certain regions of the rear of the vehicle 7 and corresponding light characteristics must be able to be generated. This is easily possible using the rear light 1 according to the invention.
- the light sources 3 of the first number 8.1 are used in particular to form a brake light, reversing light and/or direction indicator. Any light characteristic can then be projected into the environment using the light sources 3 of the second number 8.2, provided this complies with applicable law.
- a light source 3 of the second number 8.2 fails, the vehicle owner initially does not need to take any further measures. However, if a light source 3 of the first number 8.1 fails, the rear light 1 may need to be repaired or replaced in order to maintain the roadworthiness of the vehicle 2. Accordingly, if a light source 3 of the first number 8.1 fails, such information messages can be issued to a user of the vehicle 2, which contain a request to visit a workshop.
