LIGHT-EMITTING DIODE WITH HIGH LIGHT EFFICIENCY AND ENCAPSULATION METHOD THEREOF

摘要

A light-emitting diode with high light efficiency, comprising a base plate (40), at least one light-emitting chip (30), at least one first electrode (32), at least one second electrode (34) and a transparent encapsulation body (26), wherein the light-emitting chip is arranged on the base plate; the first electrode and the second electrode are electrically connected with the light-emitting chip; the transparent encapsulation body wraps the first electrode, the second electrode and the light-emitting chip; a reflecting cup (50) is encapsulated between the light-emitting chip and the transparent encapsulation body and is provided with a reflecting curved surface (51), a part of light rays generated by the light-emitting chip are totally reflected to the transparent encapsulation body on a critical position of the transparent encapsulation body and air, and the reflecting curved surface is used for reflecting the reflected light rays out of the transparent encapsulation body. The light-emitting diode can enhance the light emission efficiency by more than 30 percent through test simulation calculation.
