Thin high-performance LEDs

OSRAM Opto Semiconductors has supported laboratory scientists Fraunhofer, known to readers MobileDevice. ru, thanks to developments in various fields, from the German proud of Jena had advanced research to develop ultra-small LED modules. This study has brought scientists to the award Future Prize 2007.

During the past 40 years LEDs have been used almost anywhere where there were small light sources are needed. The current scope of application includes a variety of automotive lights, such as reversing or braking. However, their power and brightness was insufficient to make full use, but now, thanks to the efforts of scientists, old technology has the potential to get a new birth. The project was named OSTAR.

LED- modules of the new generation are the result of coordinated work in two directions. Semiconductor components developed by OSRAM Semiconductors, while researchers concentrated on Jena optical component. Work with the ultra LEDs, OSRAM started back in 1999. The decisive step was taken at a time when developers were able to extract the light from only one half of a spherical light-emitting diode. For maximum efficiency it is necessary and appropriate LED optical equipment, which was developed by Fraunhofer laboratory. The system consists of primary and secondary lenses. The primary lens collects the light emitted by the LED, while the second makes a uniform beam.

LED- modules of the type already used in many different products, such as digital projectors on the autonomous power. Demand is growing for development. In addition, the modules will be increasingly used as a backlight for the digital TV, the sources of infrared radiation required for obstacle detection systems in cars. No less popular, and the system will use the full coverage «OSTAR Lighting». These systems will become standard for automobile headlights in 2008.
