OSRAM launched a new generation of high current LED

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

The new OSTAR Compact provides more light output, while the package size is as small as the previous version, only 3.9 mm x 3.6 mm, so the small projector can achieve a higher brightness without increasing the size. The new LED drive current increased from 4 A to 6 A of the previous version, in the pulse mode (typically 120 Hz, 2 ms, Ts = 25 ~ C) under the amber light brightness can reach 350 LM, up to 600 LM and the blue green light can reach 165 lm. Due to the use of new packaging materials, the new LED thermal resistance from the old version of 6 K/W to 3 K/W, so it can be more effective heat dissipation.

The high-power LED using 2 mm chips, showing a significant increase in overall performance, mainly due to the improved epitaxial process and the realization of a more uniform power distribution through the additional bonding line. OSRAM Opto Semiconductors, Germany headquarters LED projection Marketing Manager Wolfgang SchnabEL said: This allows us to successfully design a higher current processing capacity of the compact LED. Our new OSTAR Compact provides a higher power for small projectors, allowing these devices to maintain a small size at the same time, greatly enhance the brightness. "

A new generation of LED with high current capability extends the OSTAR Compact LED product portfolio for projection applications. The product portfolio also includes a LED with a side length of 750 m and a full color LED using a 1 mm chip.
