LED module optimized for high operating currents and temperatures on ceramic AlN board.

Compared to other light sources, LEDs distinguish themselves by their energy efficiency and durability. They not only make it possible to reduce the global energy demands for lighting, but also lower costs for consumers. Their high purchase price, however, can often become an obstacle and deter potential buyers. Besides aiming to reduce the production costs of LEDs, the project also focuses on intelligent sensor systems. The developments are further complemented by market and acceptance research.
