Light-emitting diodes pack and its packing method

Abstract

The invention is concerned with the bundle and packaging method of LBD. It formed by a couple of isolated exterior derivation connection ends, and there is a cup-shaped down-lead frame of baffle-board at the end of one connection end, and a LBD connects with the baffle-board of the said down-lead frame. The LBD connects with the wire of exterior derivation connection end of the down-lead frame in type of electricity connection. There is macromolecule resin to protect the LBD and the organic and un-organic mixed phosphor grain with organic phosphor molecule in the multi-hole un-organic grain of chemic matter ejected to the baffle-board. It also owns a molding part to protect and mold the said macromolecule resin, wire, a part of macromolecule resin and down-lead frame. Because the ejected LBD owns the macromolecule resin for dispersing organic and un-organic mixed phosphor grain of the organic phosphor, the decentralization is easy to get white light with high brightness and high efficiency to keep the safety of organic phosphor without lose of light.

Description

technical field [0001] The invention relates to the technology of LED packaging (Package) and packaging method thereof. Background technique [0002] In general, light emitting diodes are small, can emit brightly colored light, have good initial drive characteristics and shock resistance, and have the advantages of being as robust as ON / OFF lighting. [0003] Due to such characteristics, various indicators and various light sources can be widely used. [0004] Recently, super-brightness and high-efficiency R, G, and B light-emitting diodes have been developed, and large-screen light-emitting diode display devices using light-emitting diodes have become common. [0005] Such a light-emitting diode display device can be operated with a small power consumption, and has good characteristics of light weight and long life. [0006] In addition, light-emitting diodes have recently been tried to make white light-emitting light sources. [0007] In this way, in order to obtain whi...

Problems solved by technology

[0020] In addition, in order to prevent the aggregation phenomenon between the particles, the surface treatment is basically required, so that as time goes by, the aggregation phenomenon between the particles occurs, resulting in a decrease in efficiency.

[0021] like figure 1 As shown, if the dispersion is not uniform, uniform light emission cannot be expected. The higher the phosphor content, the more serious the problem will be, and color spots will occur, which will infinitely reduce the efficiency of the device.
