Description

technical field [0001] The invention relates to the technical field of fluorescent powder materials, in particular to an LED fluorescent powder adhesive. Background technique [0002] As a new type of green and environment-friendly solid-state lighting source, LED has become an inevitable trend of future development, and the era of new lighting sources represented by LED is increasingly showing its advantages. LED (Light Emitting Diode) is a solid semiconductor material that can convert electrical energy into visible light, and it can directly convert electrical energy into light energy. The inherent characteristics of LED determine that it is the most ideal light source at present, and it is widely used in photoelectric systems. Compared with other light sources, LED has energy saving, safety, long life, low energy consumption, less heat generation, high brightness, waterproof and shockproof , easy dimming, concentrated beam, easy maintenance and so on.

AI Technical Summary

Problems solved by technology

[0003] Phosphor is very important to LED manufacturers, especially white LED. There are many ways to realize white LED. The most common and mature one is to apply a layer of yellow phosphor on the blue chip to make blue light It is mixed with yellow light to form white light, so the material of the phosphor powder has a great influence on the attenuation of white light LEDs. The existing phosphor powder has the problem of accelerating the aging chip
