LED Technology in Rear Lamps

Using red and amber LEDs for rear functions is already state of the art. LEDs create light by voltage-induced recombination processes in a semiconductor layer. The emitted light is determined in its colour by the internal structure of the LED. Compared to conventional incandescent bulbs, the main advantages of LEDs are their high lifetime (up to 100.000 hours), their low energy consumption due to the efficient conversion of electrical power into optical power and the small depth of the modules. LEDs also offer a vast variety of fascinating innovative styling possibilities. Moreover, the switch-on-time is very short. This provides a safety benefit to following vehicles in situations requiring fast breaking response. The light intensity of the break light can be adapted to the breaking intensity. This allows the development of adaptive rear lamps, which can adapt their behaviour to different driving conditions.
