The device 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. Likewise, adaptable cornering light and spot light can be implemented for illuminating possible obstacles at the edge of the carriageway.
Multi-chip LEDs with higher performance classes are required for use in headlights, and the Osram Ostar Headlamp LED range features homogeneous luminance and temperature stability, and is therefore especially suitable for high power applications. This is the reason why LEDs of this family have been used since 2008 for various automotive lighting functions.
A distinct bright-dark contrast of 1:65 between illuminated and non-illuminated chips is required to achieve a sufficiently efficient lighting profile. 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 Osram Ostar Headlamp Pro is to be unveiled at the ISAL 2013 trade fair on September 24/25, 2013 in Darmstadt, Germany.
