Abstract

The invention belongs to the technical field of LED packaging, and discloses fluorescent glue for improving light spots. The fluorescent glue is characterized in that the fluorescent glue contains thefollowing components in parts by weight: 15-40 parts of fluorescent powder; 1-5 parts of diffusion powder; and 55-84 parts of glue, wherein the fluorescent powder is one of silicon-based nitride, europium-doped nitrogen oxide, aluminate and Ga-YAG or more. The invention also discloses a packaging process adopting the fluorescent glue. The invention aims to provide fluorescent glue capable of improving light spots and the packaging process employing the fluorescent glue. Through the improvement of the fluorescent glue, the settling speed of the fluorescent powder is reduced, and the fluorescent powder is effectively and uniformly diffused, so that the refraction route of emergent light is changed, the required color is maximized, the output of other miscellaneous colors is reduced, the surface wrinkling phenomenon of the glue is improved, and the refraction of the light is increased to improve light spots.

Description

technical field

[0001] The invention relates to the technical field of LED packaging, in particular to a fluorescent glue for improving light spots and a packaging process thereof. Background technique

[0002] In the prior art, the overall viscosity of the fluorescent powder mixed with the glue is not enough, and the speed of the sedimentation process is relatively fast, and the phosphor powder diffuses unevenly, resulting in uneven light color of the product and the formation of light spots.

[0003] The Chinese patent "A packaging process for white light LED" (application number CN201210334557.X, publication date 2013-02-06) discloses a packaging process for white light LED, including the following steps: mixing, phosphor powder, diffusing agent and glue Mix according to the proportion, stir manually for 5-20 minutes, then use the machine to stir and vacuumize to obtain fluorescent glue; dispense glue, use a glue dispenser to evenly coat the fluorescent glue on the inner ...
