Lattice Power's High Output GaN-on-Silicon LED PAR38 Lamp Is Selected As A Top Architectural Record Product

Lattice Power, the first company to commercialize high performance, low cost GaN-on-Silicon LEDs, announced today that its new NUP-PAR38 LED lamp has been chosen by Architectural Record magazine as one their 2014 Record Products. The company's new proprietary GaN-on-Silicon LED PAR38 LED lamp delivers outstanding efficacy, superior brightness and excellent color rendering.

Lattice Power 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, Lattice Power is able to manufacture high performance, consistent quality and extremely reliable LEDs. The company's breakthrough GaN-based LEDs on silicon substrate offer exceptionally high light density and better thermal dissipation.

The company's GaN-on-Silicon LED NUP-PAR38 lamp has the industry's highest lumen output without active cooling—2000 lumens at 27W. An innovative thermal pipe heatsink provides efficient heat dissipation and eliminates the need for active cooling. Furthermore, the lamp has the highest power and lumen density from a single emitter LED and the lowest thermal resistance from an integrated package at 0.25C/W.  The 27W PAR38 LED lamp is available in various color temperature.

A jury of six professionals selected the best new products of the year from entries submitted for Architectural Record magazine's annual competition. Jurors were asked to rate the entries on the criteria of innovation, usefulness; and - where applicable- aesthetics.
