Improved Light Extraction for Solid State Lighting
SUMMARY Lehigh University has developed a new, low-cost method to achieve enhanced light extraction efficiency for III-Nitride LEDs. Conventional LEDs with planar emission surface suffers from limited external quantum efficiency. The large refractive index difference in the semiconductor / air interface results in total internal reflection. This le...
