raviolet light or near infrared light. However, photons emitted pn junction non-directional, and immediately fired in all directions have the same probability, therefore, not all the light generated by the die can be released, depending on the quality of semiconductor materials, structure and geometry of the die , the package internal structure and encapsulation materials, improved LED applications require internal and external quantum efficiency. Conventional-type LED package 5mm is a square of
