Bridgelux, a developer and manufacturer of LED lighting technologies and solutions, has beaten its previous industry record for highest Lumen per Watt values for GaN -on-Silicon.

Both are more expensive than silicon. As a result, production costs have inhibited the widespread adoption of LED lighting in homes and commercial buildings.

Bridgelux says its technology process has the potential to significantly drive down the cost of manufacturing LEDs and make them competitive to conventional white lighting technology. We are very pleased with the pace of our progress in this area, and we will continue to aggressively develop our GaN-on-Si processes in order to drive the migration of LED commercial production from sapphire to silicon substrates.

Our first commercially available GaN-on-Si products remain on schedule for delivery to the market within the next two years.

Bridgelux Takes GaN-on-Silicon To Another Level

This mismatch can cause the epitaxial films to crack, or the wafers to bow, either during epitaxial growth or at room temperature. Bridgelux’s proprietary buffer layer process produces crack-free wafers that are virtually flat at room temperature. The LEDs have very low forward voltages, 2. At a drive current of 1 amp the LEDs emitted 1. Wavelength uniformity of sigma 6.


Bridgelux, which maintains an asset-light operating model, is uniquely well-positioned to benefit from the transition to silicon substrates. Leveraging existing semiconductor fabs via partnerships with established semiconductor manufacturers has the potentially impact production costs, margins and returns on invested capital.
