METHODS FOR MANUFACTURING LIGHT EMITTING DIODE AND LIGHT EMITTING DEVICE

摘要

The present invention provides manufacturing methods of an LED and a light emitting device. The manufacturing method of the LED includes: providing a substrate; forming on the substrate an LED chip and a second electrode successively; forming a lens structure covering the second electrode; coating the lens structure with fluorescent powder; forming a plurality of evenly distributed contact holes on a backface of the substrate, the contact holes extending through the substrate and to the LED chip; and filling the contact holes with conducting material till the backface of the substrate is covered by the conducting material. The LED has a high luminous efficiency and the manufacturing method is easy to implement.
