Light emitting diode and method of making the same |
摘要 |
The present invention provides a structure of white light-emitting diode (LED) and a method of making the same. The structure according to the present invention comprises two LED chips that have light-emitting layers of multi-layer epitaxial structure and emit the lights of one or more colors. The structure comprises an LED emitting the visible light of short wavelength, and another LED emitting the visible light of long wavelength. Wherein, at least one chip in the present invention has two or more transition energy levels used for emitting two or more colored lights. With the use of the present invention, multiple colored lights emitted by the LED can be mixed into full-spectral white light source having excellent color rendering property and high light emitting efficiency. The white LED in the present invention is an ideal light source for general-purpose illumination applications
