NORTHVILLE, Mich., March 17, 2010 – The Ostar high-power LED from Osram Opto Semiconductors has been developed for use in automotive daytime running light applications based on the use of lightguides.
The surface-mount technology (SMT) LEDs’ compact dimensions and ability to drive high currents make them suitable for use in both existing and new headlight designs.
In addition to the usual point-like LED lighting solutions, linear or 2-D designs can be produced with only a small number of semiconductor light sources.
The LEDs are available in the finely graded color groups that meet ECE/SAE color binning requirements, thereby bringing color harmony to the front of the vehicle. With a power draw of 5 W and an operating current of 1.4 A, the LEDs produce typical brightness of 300 lm, and their 2-mm² chip provides high luminance.
Optimum heat removal rate is 6 K/W, making them suitable for the high-temperature zones at the front of an automobile, and they do not require a reflector or lens. The company says that the LEDs will last as long as the vehicle. The red and yellow versions can be used for signal lighting.
