REGENSBURG, Germany, Sept. 26, 2012 — The Oslon Black Flat LED from Osram Opto Semiconductors GmbH is a light source for automotive front lighting systems that offers uniform light distribution, thermal stability and good contrast. It is equipped with state-of-the-art chip and packaging technology and a ceramic converter.
The LED uses UX:3 chip technology that delivers high light output even at high currents. With a power draw of 2.3 W and an operating current of 700 mA, it achieves typical luminous flux of 200 lm at 25 °C. If operated at 1.2 A, it can achieve up to 270 lm, even with an application temperature of 100 °C in the chip.
Typical thermal resistance is 4 kW. The thermal coefficient of expansion of the LED’s black quad flat no-leads package is matched to the coefficient of expansion of the metal core board. The LED is fully AECQ101 automotive-qualified. It lasts for more than 100,000 h at 700 mA and a chip temperature of 60 °C.
It is designed without a lens in a low-profile and flat configuration that maximizes optical incoupling. Its luminance is two to five times higher than comparable LEDs in its class at 70 to 100 million cd/m², according to the company.
Encapsulation of the chips directly in the package produces a defined light/dark boundary in the light pattern and, in conjunction with advanced packaging technology and the ceramic converter, a uniform distribution of light and good contrast ratio on the road.
