In the new approach, electronic activation of the LED is integrated in the chip, resulting in a much higher resolution, while still meeting limited space requirements. The number of segments is limited due to the restricted space in the headlight. Additional electronic components are required to switch light segments on and off.
In the current generation of adaptive headlights on the market, several LED components are installed in the headlights side by side and on top of each other. For the implementation, Osram Opto Semiconductors, Infineon, and the Fraunhofer Institute for Reliability and Microintegration (IZM) developed an innovative LED chip with 1,024 individually controllable pixels. The project, which was funded by the German Federal Ministry of Education and Research (BMBF), has now been successfully completed after three and a half years with the production and field test of headlight demonstrators. As a result, such shifting headlights no longer have to be dimmed on country roads. At the same time, the beam of light does not shine on the heads of oncoming drivers, which means they’re not dazzled. This allows the driver to see these vehicles more clearly.
In addition, with the aid of sensors in the vehicle, the surroundings can be analyzed in order to illuminate oncoming traffic. The light can be adapted to take account of every conceivable bend in the road so that there are no dark peripheral areas. This means that the headlight can be adapted very precisely to suit the respective traffic situation to ensure optimum light conditions at all times without dazzling other drivers. Both headlights contain three LED light sources, each with 1,024 individually controllable light points (pixels). The demonstration model was developed by overall project manager Osram in collaboration with the project partners Daimler, Fraunhofer, Hella and Infineon.
