With »heatsinkless LEDs« ams OSRAM is revolutionizing classic headlights for high beam/low beam and is aiming to replace halogen lights in the long run.
Existing headlights in the market rely on heat sinks for thermal management. In contrast, the basic idea for cooling the LEDs within the system is to rely on free convection starting from metal core PCBs instead of using dedicated heat sinks. Due to a high electrical efficiency of the light sources, low thermal management efforts and the possibility to use low cost PCBs, a cost optimized system can be designed. The enhanced space also allows for more design freedom while still keeping the required brightness.
Additional high beam spot lamps for extra long range can be realized by high luminance LEDs. Also see laser light for long range illumination.
