Affordable LED solution for the subcompact automobile market

October 31, 2012 // By Christoph Hammerschmidt
With the Oslon LX, Osram Opto Semiconductors is offering a LED component for applications in the volume automotive sector. The focus is on the essential functions of brightness and quality so these white light emitting diodes are affordable even for installation in subcompact vehicles. The products aims at applications as daytime running lights and fog lights.

The Oslon LX LED is based on the interplay between tried and tested package and converter technologies on the one hand and a new chip technology on the other. This new technology offers the usual high quality standards and light output typical of all the LED products from the Regensburg company.

With its design goal of producing high brightness at an affordable price. the Oslon LX is ideal for applications in which high light output and high energy efficiency are crucial factors – such as fog lights and daytime running lights. Low beam and high-beam applications are also possible, however, with a combination of multiple LEDs.

The Oslon LX LED is based on the company's UX:3 chip technology with a proven tried silicon converter. At a temperature of 25 degrees Celsius (in the chip) the LED produces 125 lumen from a current of 350 mA; at higher temperatures of around 100 degrees Celsius, it still achieves a luminous flux of 100 lumen. The LED lens has a beam angle of 120 degrees. Thus, the LED meets the established standard for reflector solutions in automobiles and that the systems used in the compact subcompact segments can be retained. In common with the other successful LEDs from the same vendor, the package for the Oslon LX is compact, measuring only 3x3 mm2. The solder pad design is identical to that for the other Oslon automotive components.

The Oslon LX will be showcased for the first time at electronica 2012 (A3.107).
