UNIVERSAL TRAFFIC LIGHT LUMINAIRE |
摘要 |
A traffic light luminaire, comprising at least one light source, a collimating device for collimating light emitted by the at least one light source, a light distribution device for spreading the collimated light within a specific solid angle with a specific luminous intensity distribution, is characterised in that the light source is a high brightness light source, and that the light distribution device is a microstructured distributor having a microstructured 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. |
