A new era has dawned in automotive lighting. The Cadillac Escalade Platinum is the first sports utility vehicle (SUV) in the world to be fitted with LED headlights as standard. OSRAM LEDs perform all the functions in the headlights supplied by Hella – low beam, high-beam, daytime running light, position lights and side marker lights. The luxurious automobile will be launched in 2008.
As a technology leader in automotive lighting, Hella KGaA Hueck&Co has equipped the new headlights entirely with light emitting diodes in the typical vertical Cadillac style. The innovative headlight manufacturer opted for high-power LEDs from OSRAM Opto Semiconductors. Each headlight contains seven OSTAR Headlamp LEDs – five for low beam and two for high beam. Daytime running light is provided by dimming the low beam. This means there is no need for an extra light source. This intelligent solution is only possible with LEDs. Each headlight also has a position light with white Advanced Power TopLEDs and a side marker light with yellow Power TopLEDs.
High-luminance light sources
The OSTAR Headlamp LED was developed specifically to meet the requirements of Hella, the headlight manufacturer. It is among the brightest LEDs for use in the automotive sector. With a color temperature of 5500 Kelvin, much higher than the 4000 Kelvin of xenon light, these tiny light sources create a light with the same color impression as natural daylight. The OSTAR is particularly robust and can withstand ambient temperatures from -40° to +125°C. Even when placed near a high-power engine it will continue to provide excellent performance.
