MITSUBISHI TECHNOLOGY - MATERIALS
Mitsubishi Chemical is a world-leading supplier of phosphor to the global lighting industry. Phosphors
play a key role in converting blue LED light to the natural white light that humans enjoy. The quality of the
phosphors is crucial in ensuring that the colours do not degrade over time which could result in serious
decline in the white light output.
Furthermore, Mitsubishi’s experience and understanding of the four key technical elements of an LED bulb
- electronics, the LED, thermal management and optics – ensures that the products are highly optimised
and deliver the best in class in terms of efficiency and performance.

GaN ON GaN
It has been widely reported that LEDs using a GaN epi on GaN substrate
structure chip is the future for LED lighting, and Mitsubishi is one of the pioneers in this field. GaN on GaN
theoretically offers far improved power density performances compared to standard GaN on sapphire
structures because there is a crystal lattice match at the atomic level so no buffer layers are needed. This
results in far fewer defects and a simpler device architecture. By minimizing defects in the active layer,
current densities and light output are projected to be 5 to 10 times higher with GaN on GaN chips,
allowing for much smaller lighting fixtures and narrower beam angles.
