The world’s first monolithic white LED structure produces light with a color quality very close to that produced by incandescent lamps and sun light on Earth. The Kamiyama LED combines the very low energy consumption of LED light sources with a high color quality – similar to that of halogen lighting. The management believes that the Kamiyama LED will be the first choice for consumers of indoor lighting and in LCD backlighting applications. The Kamiyama LED combines:
- a high energy efficient,
- a high color quality and stability
- a highly efficient heat transport with
- a long lifetime.
The Kamiyama LED does not contain mercury like compact fluorescent lamps.
The key technologies in the Kamiyama LED are the florescent silicon carbide substrate, the near-UV excitation source and the moth-eye structure for enhanced light extraction efficiency.
Moth-eye Patterned Substrate
The operation temperature of the Kamiyama LED is 200 degrees centigrade. The high operation temperature enables a 40% higher heat transport in heat sinks compared to what is typical in phosphor coated white LED’s.
