Osram Ostar Compact enables daytime running lights using only two LEDs

The OSTAR Compact from OSRAM Opto Semiconductors has been developed for special-purpose use in automotive headlights. The high-power LED is designed for Daytime Running Light (DRL) applications based on the use of light guides.

Its compact dimensions and its capability to drive high currents make it ideal for both existing and new headlight designs. In addition to the usual point-like LED lighting solutions, linear or two-dimensional designs can be produced with only a small number of semiconductor light sources.

Use of LEDs for daytime running light applications is on the rise – and not only in top-of-the-line models. These energy-saving light sources are fast becoming the light source of choice in mid-range vehicles as well.

With the surface-mounted OSTAR Compact, OSRAM Opto Semiconductors is expanding its portfolio of LEDs for DRL applications. The entire automotive LED lights coverage of a headlight manufacturer can now be matched well because these high-current LEDs, such as the OSTAR Headlamp and the OSLON ECE, are available in the finely graded color classes of ECE color grading bringing color harmony to the front of the vehicle.

With a power draw of 5W and an operating current of 1.4A, the OSTAR Compact achieves a typical brightness of 300 lm and its 2 mm2 chip provides high lighting performance. With this small, high power light source light guide, the LED lights systems can be produced with just two LEDs. This rugged component also has the optimum heat removal rate of 6 K/W, making it ideal for the high-temperature zones at the front of an automobile. OSTAR Compact does not need a reflector or lens.

"Light guides are available in many different designs, from a simple rod to complex 3D versions", said Peter Knittl, Marketing Director for the Automotive Division at OSRAM Opto Semiconductors. "To provide new designs in different forms and a choice for point-like DRL designs, you need one thing above all else – a small high-power LED light source."

Thanks to the SMT package the OSTAR Compact is easy to handle. It will last as long as the vehicle, eliminating the need for replacement and therefore saves on costs. The red and yellow versions of OSTAR Compact can be used for signal lighting.
