Multiple-junctions GaN-on-Si power LEDs output from 1 to 15W

October 18, 2016 // By Julien Happich
Plessey's 7070 high power LED range (part number PLW7070GA) takes full advantage of the company's GaN on silicon MaGIC technology, integrating multiple junctions into a single chip to eliminate shadow effects and provides optimised far-field imaging.

Compatible with industry standard secondary optics and operating at input currents from 350mA to 3A, 1W to 15W power, the high power LEDs reset the bar for performance in low-cost single chip LEDs for demanding outdoor and commercial lighting applications, and are available in a full range of CCT and CRI options.

The 7070 range comes with a custom Aluminium Nitride ceramic lensed package exhibiting a low thermal resistance, less than 2°CW -1, combined with a high maximum junction temperature of 135°C for good thermal management in demanding thermal environments.
