OSRAM Reveals Two New LED Prototypes for Car Headlights
Sep 23, 2011
OSRAM recently revealed it will be adding two new LED prototypes, the OSLON Black Flat and OSRAM OSTAR Headlamp Pro. These two new models will be showcased by the LED innovator at ISAL (Sept. 26-28, 2011).
The OSLON Black Flat is the most recent addition to the Black Series, equipped with a ceramic converters and QRN package (Quad Flat No Leads). Compared to its predecessors in the series, its thermal resistance is 20% better at 5 K/W. Also, the thermal coefficient of the special material, combined with the equal coefficient of expansion of the metal core board yields high stability.
Installation of this model is slightly different because the new LED does not require a lens, so it is an option to place the light near the light guide (among other added choices). However, the solder pad is familiar, identical to what the rest of the Black series features, leading to increased light output with the same board design.
The second model, the OSRAM OSTAR Headlamp Pro, can "meet a wide range of requirements" related to "output and adaptability to ambient conditions." It is unlike previous models in improved light uniformity, thermal stability, and brightness.
Headlight manufacturers will appreciate the lower costs from the OSTAR prototypes. They present the classic case of improving quality while decreasing cost. The ability of these chips to be controlled individually or in series allow for AFS functionality (Adaptive Frontlighting System), which allows for matrix chip solutions. Their higher thermal resistance and efficiency will make the two prototypes ideal for headlights.
