SemiLEDs launches 135lm I-Do LED chip

LED chip and component maker SemiLEDs Corp of Boise, ID, USA (which has chip fabrication facilities in Hsinchu Science Park, Taiwan) has launched a new chip in its ultra-high-brightness LED product portfolio.

Available for sampling now (for high-volume production in April), I-Do is the second generation of SemiLEDs’ I-Core AK series of LEDs, which are designed to provide further improvements in brightness, reliability and overall efficiency.

The firm says that the I-Do LED features a new design with improved reliability, optimized current distribution and lower forward voltages at high current operation of 700mA and 1A. It adds that the I-Do is not only more reliable but also significantly brighter, as the design produces improved internal quantum efficiency. In a white light package, a 45 mil I-Do chip can deliver up to 135lm at 350mA with a correlated color temperature (CCT) of 5000–7000K, more than a 10% improvement over the previous generation.

With increased efficiency, reliability and what is claimed to be the lowest thermal resistance in the market, SemiLEDs says that the I-Do chip suits small-footprint, high-performance applications.
