OSRAM green LED significantly enhance the brightness aimed at business projector market

December 17, 2010 - News - Chinese 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, to emit white light, green light ratio must be greater than the proportion of red or blue, and green LED brightness upgrade will significantly affect the brightness of the whole system. Using these LED prototype system can provide the overall brightness 2000 LM, 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.

OSRAM Opto Semiconductors Germany headquarters marketing director Volker Mertens said: "green LED brightness doubled, this is a huge leap forward, will break through the LED applies only to small projector restrictions." LED has high color saturation, so it can achieve excellent image reproduction, plus it 3 million hours of long life, the LED projector requires almost no maintenance. In contrast, high intensity discharge lamp about every 400 hours to replace a. In addition, the response speed of LED projector switch faster, and support the stepless dimming mode. 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.
