  • Universal traffic light luminaire
    Patent number: 9599763
    Abstract: A traffic light luminaire includes at least one light source, a collimating device for collimating light emitted by the at least one light source, and a light distribution device for spreading the collimated light within a specific solid angle with a specific luminous intensity distribution. The light source is a high brightness light source, and the light distribution device is a microstructured distributor having a micro-structured surface, wherein each equal-sized macroscopic section of the microstructured distributor contributes to the luminous intensity distribution in the same way within said whole specified solid angle. Thereby a low maintenance traffic light luminaire is provided which generates a homogeneous light distribution for a variety of trail arrangements (right curve, left curve, straight line) independent of the distance of the viewer.
