Abstract
The disclosure relates to a lighting device, in particular for integration into a vehicle surface, having a cover with optically opaque surface areas, a light-source carrier, arranged behind the cover and having a plurality of light sources, and signal structures which are arranged between the surface areas and can be illuminated for light emission, wherein different signal patterns can be adjusted by selective control of certain of the light sources for trans-illumination or illumination of one or more associated signal structures. The disclosure further relates to a vehicle, having such a lighting device, and to a method for carrying out various signal functions with such a lighting device.
Claims13
A lighting device for integration into a vehicle surface, comprising:
- an exterior cover having optically opaque surface areas,
- illuminable light-transmissive signal structures formed in the exterior cover between the opaque surface areas for light emission, and
- a light source carrier arranged behind the exterior cover and having a plurality of light sources arranged in a uniform matrix over a surface of the light-source carrier, wherein each signal structure is illuminated by a group of light sources selected from the plurality of light sources in the uniform matrix,
- wherein different signal patterns can be adjusted by means of selective activation of certain of the light sources for trans-illumination or illumination of one or more associated signal structures.
A vehicle, in particular an electric vehicle, having a lighting device for integration into the vehicle surface and a control device, wherein the lighting device comprises:
- an exterior cover having optically opaque surface areas,
- illuminable light-transmissive signal structures formed in the exterior cover between the opaque surface areas for light emission, and
- a light source carrier arranged behind the exterior cover and having a plurality of light sources arranged in a uniform matrix over a surface of the light-source carrier, wherein each signal structure is illuminated by a group of light sources selected from the plurality of light sources in the uniform matrix,
- wherein different signal patterns can be adjusted by means of selective activation of certain of the point light sources for trans-illumination or illumination of one or more associated signal structures,
- wherein the control device controls the point light sources, wherein the point light sources are programmably controllable by the control device so that certain signal structures can be selectively illuminated in whole or in part for light emission in order to perform a specific signal function.
A method for performing various signal functions of a lighting device for integration into a vehicle surface, wherein the vehicle includes the lighting device and a control device, wherein the lighting device comprises:
- an exterior cover having optically opaque surface areas,
- illuminable light-transmissive signal structures formed in the exterior cover between the opaque surface areas for light emission, and
- a light source carrier arranged behind the exterior cover and having a plurality of light sources arranged in a uniform matrix over a surface of the light-source carrier, wherein each signal structure is illuminated by a group of light sources selected from the plurality of light sources in the uniform matrix,
- wherein different signal patterns can be adjusted by means of selective activation of certain of the point light sources for trans-illumination or illumination of one or more associated signal structures,
- wherein the control device controls the point light sources, wherein the point light sources are programmably controllable by the control device so that certain signal structures can be selectively illuminated in whole or in part for light emission in order to perform specific signal functions, wherein the method comprises:
- selecting a specific signal function;
- and
- performing the selected signal function by controlling associated point light sources to illuminate the signal structure or signal structures, disposed in front of it, from the back to emit light.
