Short Description

Headlights can be turned into a high-tech light source with laser technology. Together with OSRAM, the market leader in automotive lighting, CTR is researching into a light source unit for automotive laser lights.

SENSOR ELEMENT - Technology and Design

Together with Osram, the market leader in automotive lighting, the CTR team was exploring novel light source units for automotive laser lights. Work included a comprehensive optical design, taking into account different laser technologies, optical components, opto-mechanical arrangement and the achievable light budget. Optimization of mechanical and electronic factors is crucial in order to achieve realistic specifications for the overall system. Laser safety is another key factor which has to be ensured.

SENSOR MODUL - Prototype

A fully functional prototype was built, based on laser-activated remote phosphor (LARP) technology. Here the blue light from the high-power laser diodes is converted into pure white light using a special converter medium. The emitted light cone is shaped by the headlight’s optics to create a beam which illuminates the road. MEMS technology included in the unit allows adaptive definition of the illuminated area which can be used to avoid glaring of other road users or to highlight possible sources of danger.

SENSOR SYSTEM/ application - mobilE security

Laser technology creates completely new dimensions in headlight design. Laser diodes provide superior beam quality and brightness while consuming 30% less energy. Furthermore, due to their tiny package headlights can be made even smaller in the future - without having to compromise on light intensity. Drivers primarily benefit from the fact that such headlights have the longest range currently available. That ensures improved visibility and therefore greater safety on the roads.
