Abstract

The invention discloses a high-power LED (Light Emitting Diode) bracket which comprises a conductive pin and a base wrapping the conductive pin. A cavity is formed at the top of the base. A heat sink is fixedly arranged at the bottom of the cavity. The base is made of a high temperature resistant material. The high temperature resistant material is mainly a liquid crystal high-molecular polymer and contains a plurality of filler particles. The high-power LED bracket provided by the invention has the advantages of high heat resistance, high light emitting efficiency, high ultraviolet light shielding performance and low cost. Compared with the PPA (Phenyl-Propanolamine) bracket currently used, the high-power LED bracket provided by the invention has higher heat resistance so that the bracket has good compatibility with a gold and tin eutectic solder which welds the LED onto the base, and therefore, the production efficiency of an LED lamp is improved. Compared with the ceramic bracket currently used, the bracket disclosed by the invention has the advantage that high-efficiency and low-cost production can be realized by an injection molding method. In addition, the invention further discloses a high-power LED packaging structure using the bracket.

Description

technical field

[0001] The invention relates to a bracket for LED packaging, in particular to a high-temperature-resistant bracket suitable for packaging high-power light-emitting diodes (LEDs), and a high-power LED packaging structure using the bracket. Background technique

[0002] White light emitting diode (Lighting Emitting Diode) has many advantages such as high efficiency, long life, high reliability, environmental protection and energy saving, and flexible application. It is generally recognized as the fourth-generation lighting source and has broad development prospects. Making high-power light sources is the main development trend of LEDs in the future. With the progress of LED technology, the light efficiency of LEDs increases, resulting in more light and heat being dissipated. This requires LEDs to have better heat resistance and The ability to reflect light. The base of the high-power light-emitting diode packaging bracket is a component that reflects most...
