Multi-Chip LED Component increases AFS intelligence.

Press Release Summary:




Intended for Advanced Forward Lighting Systems (AFS), which adapt illumination direction when driving through curving roads and other scenarios, 20 x 21 mm Ostar Headlamp Pro LED component features 5 chips that can be individually controlled and switched on and off according to driving situations and positions of other vehicles. Typical light intensity at 500 mA/25°C is 710 lm (min), and transmission angle is 120°. Design eliminates need for mechanical assemblies to move headlight.

Making Headlights Even More Intelligent



New multi-chip Osram Ostar Headlamp Pro LED simplifies implementation of Advanced Forward Lighting Systems



Advanced Forward Lighting Systems (AFS), which adapt their illumination direction when driving through curving roads and other scenarios, can now be even more easily implemented by automobile manufacturers. Osram Opto Semiconductors has developed a new Ostar Headlamp Pro that offers, for the first time, a specific LED component for this particular application. The five chips of this new LED can be individually controlled and flexibly switched on and off according to driving situations and the positions of other vehicles on the road.



Thanks to LED technology, Advanced Forward Lighting Systems (AFS) can be implemented more simply than before because no mechanical assemblies are required to move parts of the headlight or the complete headlight. With the new Ostar Headlamp Pro, the individual chips are specifically switched on and off via intelligent control. The control utilizes sensors and electronic components for high beam light without glare by flexibly concealing areas within the light cone of the headlight according to the specific driving situation and with dynamic adaptation to the positions of other road users. The new LED also makes it possible for adaptable cornering lights and spotlights to be easily implemented for illuminating possible obstacles at the edge of the roadway.



The new Osram Ostar Headlamp Pro: The first LED specifically for AFS

Multi-chip LEDs with higher performance classes are needed for use in headlights, and the Osram Ostar Headlamp LED range features high-performance technology, homogeneous luminance and temperature stability, making it especially suitable for high power applications. This is the reason why LEDs of this family have been used since 2008 for a variety of automotive lighting functions. “Osram Ostar Headlamp Pro is now the first LED specifically developed for use in AFS. Its five chips -- each of one square millimeter -- can be controlled individually, forming the basis for intelligent light solutions,” explained Michael Martens, LED Product Marketing Manager at Osram Opto Semiconductors.



Optimal vision for vehicle drivers

“Intelligent headlight systems with our light emitting diodes give drivers optimal vision even on the edges of roads or with other vehicles approaching, offering better protection from possible accidents,” said Martens.  “Thanks to the five individually controllable chips, more than one road user can be concealed from view and the intermediate area is still completely illuminated.” A distinct bright-dark contrast ratio of 1:65 between illuminated and non-illuminated chips is required so that the AFS is as effective as possible and the light beam on the road is optimally transmitted. This means that concealed chips must be genuinely dark and must not be illuminated by their adjacent chips. An integrated shutter also enables a clearly defined light beam from the headlight.



The new multi-chip Osram Ostar Headlamp Pro is to be unveiled at the ISAL 2013 International Symposium of Lighting Technology on September 24/25, 2013 in Darmstadt, Germany.
