A new generation of OSRAM LED high current projector to create higher brightness

The thermal resistance of a new generation of OSTAR Compact June 15, 2010 - Chinese news OSRAM Opto Semiconductors launched with more excellent high current capability and lower, can handle currents up to 6A in pulse mode, micro projector pocket is especially suitable for small mobile devices. According to the design of small projector, brightness high power LED can effectively enhance the projector.

The new OSTAR Compact provide more light output, and the package size is as small as the previous version, only 3.9 mm x 3.6 mm, so no need to increase the size of small projector can achieve higher brightness. To improve the driving current of new from the previous version of the LED 4 A to 6 A, in the pulse mode (typically 120 Hz, 2 ms, Ts = 25 ~ C) under the amber light brightness up to 350 LM, up to 600 LM green up to 165 LM, Blu ray. Due to the adoption of new packaging materials, new LED resistance from the old version of the 6 K/W to 3 K/W, so it can more effectively heat.

This high power LED by 2 mm - chip showed greatly improved the overall performance of the epitaxial process is mainly due to the improved and engaging through additional lines to achieve the more uniform distribution of power. OSRAM Opto Semiconductors LED German headquarters marketing manager Wolfgang Schnabel projection said: "this allows us to successfully design a compact LED have a higher current handling capability. Our new OSTAR Compact provides higher luminous power for small projector, let the device maintain a small size at the same time, greatly enhance the brightness."

A new generation of LED have high current capacity expansion for projection applications OSTAR Compact LED product portfolio. The portfolio also includes the length of 750 m chip LED and 1 mm - chip full color LED.
