  • Light emitting diode and light purification method therefor
    Patent number: 11658270
    Abstract: A light emitting diode (LED) and a light purification method therefor are provided, which belong to the technical field of LED. The LED includes an epitaxial structure and a light purification layer plated on the epitaxial structure. The light purification layer includes a first reflection layer and defines multiple light-exiting holes. The first reflection layer is plated on the epitaxial structure. The multiple light-exiting holes each extend through the first reflection layer and have an aperture which is N times a preset wavelength of an exit light, N being an integer and N?1.
