LatticePower Commercializes GaN-on-Si LED Luminaires

LatticePower, will display at LIGHTFAIR International 2014 (booth #1933B) the next generation of light fixtures demonstrating the true convergence of performance, design and affordability. The company's new proprietary GaN-on-Silicon LED track, highbay and flood fixtures deliver outstanding efficacy, superior brightness and excellent color rendering. 

LatticePower has succeeded where many other companies have failed. Growing GaN material on a silicon substrate has been a vexing problem for the industry as a result of the material lattice mismatch and thermal expansion mismatch between GaN thin film and silicon substrate. These mismatches contribute to defects in the material, cracking on the wafer and poor quantum efficiency of the epi-layer.

By developing a series of proprietary technologies to overcome the mismatch problems, LatticePower is able to manufacture high performance, consistent quality and extremely reliable LEDs. The company's breakthrough GaN-based LEDs on silicon substrate offers exceptionally high light density and better thermal dissipation. 

The company's GaN-on-Silicon technology utilizes larger diameter semiconductor manufacturing process that lowers unit cost and increases throughput for significant cost reduction. Its 6-inch silicon wafer process has an advantage of at least 30% lower cost than the equivalent top-tier sapphire process.

LatticePower also has developed a unique system-in-package approach that differs from others by combining integrated GaN-on-Si LEDs with a silicon-substrate based heatsink. This new platform permits easy scalability, low cost production and automated manufacturing for lighting fixtures. 

As a vertically integrated company, LatticePower designs, engineers and manufactures all the components in its lighting products, optimizing performance for commercial applications and reducing time to market at scale. The company will display three new fixtures with its innovative GaN-on-Silicon LED technology—a track light, highbay and flood. All of LatticePower's products are certified to international standards for the general lighting market, including indoor and outdoor applications.
