The first GaN on GaN LED by SORAA on the market

New in this LED: GaN substrate, triangular shape chip, simplified epitaxial structure and an original silicon-based wafer level packaging

 SORAA has recently released the first GaN on GaN LED in a 50W halogen equivalent MR16 lamp with several new features.

SORAA smartly used the GaN characteristics like the optical transparency and the high electrical and thermal conductivity to create a unique vertical structure for these LEDs. The layers deposited by epitaxy are very thin.

A high current density per sq cm is obtained, estimated at 120A / sq cm, 4x more than sapphire LED.

The SORAA LEDs have a triangular shape to limit the internal reflection of the light and thus increase the light extraction.

An original silicon package with a multilayer mirror is used to increase the light extraction of the LED lamp.
