LED Prototypes Fire Up Headlights

The OSLON Black Flat and OSRAM OSTAR Headlamp Pro LED prototypes combine unique chip and package technologies to provide high light output, a uniform light pattern, thermal stability, and a good contrast ratio. They are matched to the requirements of headlight systems. OSLON Black Flat is the latest addition to the OSLON Black Series and is equipped with a ceramic converter and a QFN package. With a typical thermal resistance of 5 K/W, it is 20% better than the traditional OSLON Black Series. Specs include a power draw of 2.3 W, an operating current of 700 mA, and a typical luminous flux of 190 lm. The OSRAM OSTAR Headlamp Pro offers a more uniform light pattern, more useable warm lumens, and greater brightness than its OSTAR Headlamp predecessor. The 20 x 20 mm high-flux LED is available in two to five chip configurations. Typical luminous flux values are around 250 lm for a single chip (1A operating current), equating to 1250 lm for the five-chip version. The thermal resistance of the 5-chip version is 2.1 K/W, which represents a 20% improvement over its predecessor. Samples are available now and market launch is scheduled for the third quarter of 2012. OSRAM OPTO SEMICONDUCTORS, San Jose, CA. (888) 446-7726.
