OSRAM Opto Semiconductors has developed two LED headlight prototypes—the OSLON Black Flat and OSRAM OSTAR Headlamp Pro—which combine chip and package technologies to provide high light output, uniform light patterns, thermal stability, and efficient contrast ratio.

The Black Flat offers a 20% improvement in thermal resistance over OSRAM’s previous Black Series models. It features a flat-top, lens-free design, which OSRAM says makes it ideal for high-quality light guide designs. It has a power draw of 2.3 watts, an operating current of 700 milliamps (mA), and a luminous flux (a measure of visible light) of 190 lumens (lm).
 
The Headlamp Pro offers a more uniform light pattern, better thermal stability, and greater brightness than its OSTAR predecessors. The 20 x 20-mm high-flux LED is available in configurations from two to five chips for design flexibility.
 
The headlights are expected to be launched in Q3 2012.
