Until today, the green spectrum is the weak point of LEDs. Efficiency is far lower for the huge spectral range from about 500 to 570nm than it is for the other colors. NGK's approach promises nearly twice the efficiency than ever beforehttps://zmi.led-professional.com/Plone/media/technology_light-generation_evelopment-of-gallium-nitride-wafers-nearly-doubling-green-led-luminous-efficiency_Until%20today-%20the%20green%20spectrum%20is%20the%20weak%20point%20of%20LEDs.jpg/viewhttps://zmi.led-professional.com/Plone/media/technology_light-generation_evelopment-of-gallium-nitride-wafers-nearly-doubling-green-led-luminous-efficiency_Until%20today-%20the%20green%20spectrum%20is%20the%20weak%20point%20of%20LEDs.jpg/@@images/image-1200-6a1c7693bd7147afab4698f59f4c40b5.jpeg
