White-light luminescent component and its production

Abstract

The invention is concerned with the white luminous component and the manufacture method, the white luminous component includes: sets the down-lead frame of the cup-shape reflecting panel on one end of the outside fetching end that consists of a pair of outside fetching ends with interval; the LED sticking connects the down-lead frame reflecting panel; electric connects the LEB and the wire of the outside fetching ends; wraps the LEB, spreads the macromolecule resin that the organic self-luminescent material melts and the inorganic self-luminescent material separates on the reflecting panel; the molding part processes formation for the wrapped macromolecule resin, whole wires and part of the down-lead frame. The invention can not create the compatibility problem with the resin.

Description

technical field [0001] The present invention relates to the technology of white light-emitting element and its manufacturing method, which means that the polymer resin of melting organic phosphor and dispersing inorganic phosphor is coated on the light-emitting diode to make white light-emitting element, so that there will be no generation of resin and coating resin. A white light-emitting element and a manufacturing method thereof that can improve luminous efficiency and color coordinates. Background technique [0002] Generally, light-emitting diodes are small, can emit brightly colored light, have good initial drive performance and shock resistance, and can be turned on (ON) / off (OFF) repeatedly like lighting. [0003] Because of this performance, it is widely used in various displays or various light sources. [0004] Recently, R, G, and B light-emitting diodes with ultra-high gray scale and high efficiency have been developed, and large-screen light-emitting diode disp...

AI Technical Summary

Problems solved by technology

[0028] First, there will be a problem of compatibility with the coating resin, and when it is dispersed on the coating resin when there is a difference in solubility, crystallization will occur, making it difficult to obtain a uniform dispersion agent

In addition, after coating, bubbles and cracks may occur due to residual solvents or liquid resins with different physical properties during the curing process.

[0029] In addition, when using an organic phosphor with low solubility, as the amount of solvent increases, the viscosity of the coating resin decreases, making it difficult to uniform the amount of coating on the light-emitting diodes, and as the solvent volatilizes, the coating amount decreases. Will change, making it difficult to obtain uniform luminous efficiency and color coordinates

[0030] At the same time, due to the need for an additional dissolution process and mixing process, an additional process will be generated, resulting in an increase in cost

[0031] In addition, the liquid organic phosphor contains foreign substances instead of pure organic phosphors, so the contained foreign substances will reduce the luminous efficiency

[0032] Therefore, the method of mixing the liquid organic phosphor with another resin for coating proposed in Korean Laid-Open Patent No. 2003-0031061 is inappropriate, and the above problems will occur.
