Abstract

The invention provides special light-failure-resistant flour blending fluorescent glue for LED (Light-emitting Diode) white light. The special light-failure-resistant flour blending fluorescent glue comprises glue A and glue B in the weight proportion being 1:1, wherein the glue A comprises the following components in weight proportion: 48.1-55.5% of cycloaliphatic epoxy resin, 4.5-7.8% of bisphenol S epoxy resin, 2.4-3.7% of liquid thermal stabilizer, 2.4-3.7% of liquid light stabilizer, and 29.3-39.4% of phenyl silicon resin; and the glue B comprises the following components in weight proportion: 97.5-100% of heat-resistant modified anhydride and 0-2.5% of promoter. According to the components and proportion, the obtained special light-failure-resistant flour blending fluorescent glue for the LED white light has the characteristics of high light failure resistance, long service life, fluorescent powder settling resistance, high brightness and convenience in use.

Description

technical field [0001] The invention relates to the field of coating materials on the surface of LED chips, in particular to a fluorescent glue specially formulated for anti-light decay LED white light. Background technique [0002] As a pioneer of global lighting tools, incandescent lamps are gradually being replaced by a new generation of lighting tools, light-emitting diodes (LEDs), and gradually fade out of people's lives. The color variety, brightness and power of LEDs have changed dramatically over the past few years. As a new type of high-efficiency solid-state light source, LED has significant advantages such as small size, energy saving, and environmental protection, so it is widely used in indicator lights, display screens, and backlights, etc. It has not yet been able to fully play its role in the field of home and public lighting. [0003] With its excellent performance, anti-light decay materials are laying the foundation for LED lighting tools to enter thousa...
