Fluorescent glue capable of packaging white light LEDs

Abstract

The invention discloses fluorescent glue capable of packaging white light LEDs. The fluorescent glue is prepared by mixing the following components in parts by weight: 50-60 parts of allochroic silicagel, 45-50 parts of water-proof silica gel, 30-40 parts of super light clay, 20-25 parts of epoxy resin glue, 5-10 parts of colorful flashlight powder, 10-12 parts of blue fluorescent powder, 10-12 parts of red fluorescent powder, 10-12 parts of green fluorescent powder, 3-5 parts of diffusion powder, 5-8 parts of light dispersing agent, 5-8 parts of electron powder and 5-10 parts of nanometer negative ion powder. The fluorescent glue capable of packaging the white light LEDs can improve the yield of the white light LEDs; compared with traditional fluorescent glue, the sedimentation rate of the fluorescent glue can be effectively controlled, the brightness of the LEDs is improved, and thus the product quality is improved.

Description

technical field [0001] The invention relates to a fluorescent glue for encapsulating white light LEDs, in particular to a fluorescent glue for encapsulating white light LEDs which improves the white light output of LEDs. Background technique [0002] LED is a solid-state semiconductor device that can directly convert electrical energy into light energy. It has the advantages of high luminous efficiency, low power consumption, fast response, small size, long life, shock resistance and suitable for mass production. With the development and progress of science and technology, LED technology is more and more widely used in people's daily life, such as various LED lamps and LED displays. [0003] The process of packaging LED generally needs to go through steps such as solid crystal, wire bonding, glue dispensing, and baking. The fluorescent glue used in the existing process of packaging white LEDs is to add fluorescent glue to silica gel. This packaging process is due to the pho...

[0003] The process of packaging LEDs generally needs to go through steps such as solid crystal, wire bonding, dispensing, and baking. The fluorescent glue used in the existing process of packaging white LEDs is to add fluorescent glue to silica gel. This packaging process is due to the phosphor Precipitation is too fast, which will affect the white light products of LEDs and affect the brightness of LED lights
