OSRAM green LED brightness upgrade, aimed at business projector market

December 17, 2010 China - News - OSRAM Opto Semiconductors in OSTAR platform to develop a green LED prototype, the brightness is two times that of the previous generation, the emitting surface is also very uniform. This single chip LED using the latest chip technology, equipped with a green fluorescent converter. Has launched the initial sample, is trying to seek the development of LED business partner projector. OSRAM Opto Semiconductors is expected to be officially launched this LED products in 2011 summer. RGB LED has occupied the micro projector market, the next stage will be to enter the business projector market. Now, with the LED brightness green huge ascension, the birth of LED business projector has point the day and await for it. The LED brightness prototype single chip can achieve 410 LM, NM 553 emission wavelength. For the projector, in order to emit white light, the proportion of green light must be greater than the proportion of red or blue light, while the brightness of green LED brightness will significantly affect the brightness of the whole system. Using these LED prototype system can provide the overall brightness of 2000lm, just to meet the needs of business projector brightness. Therefore, the projection image size LED projector (diagonal) is expected to more than two meters. Prior to this, these applications can only be achieved through the use of high intensity discharge lamps and other traditional light source projector. Germany OSRAM Opto Semiconductors headquarters marketing director Volker Mertens said: "the green LED brightness doubled, this is a huge leap forward, will break through the LED is only suitable for small projector restrictions. "LED has high color saturation, so it can achieve excellent image reproduction, plus its 30 thousand hour long life, the LED projector requires almost no maintenance. In contrast, high intensity discharge lamps need to be replaced every 400 hours. In addition, the response of the LED projector to the switch is faster, and the stepless dimming mode is supported. Therefore, they can adjust their brightness according to the ambient light, so as to save energy consumption. Because each color can be electronically controlled, the color gamut is extremely flexible.

Compared with the traditional projector light source, the photometric value under the same projection image LED projector itself will become more bright, thanks to the LED ultra high color saturation. On OSRAM Opto Semiconductors OSRAM SIEMENS industrial sector subsidiary, is also one of the two largest lamp manufacturers in the world, its subsidiary OSRAM Opto Semiconductors GmbH (Germany Regensburg) provide semiconductor technology lighting, sensors and visual applications solutions for its customers. OSRAM Opto Semiconductors with production line in Germany, Regensburg and Malaysia Penang, its North American headquarters in the United States California Sunnyvale, Asia headquarters in Hongkong, and also has offices around the world.
