Abstract
Description
technical field
[0001] The invention belongs to the technical field of LED lighting, and in particular relates to an LED fluorescent powder coating method. Background technique
[0002] At present, LED phosphor powder is usually mixed with glue first, and then glue is applied to the surface of the LED. Taking blue LED as an example, after the blue light is emitted from the LED, part of the blue light and the fluorescent powder are converted into yellow light, yellow light and The blue light mixes so that what is emitted becomes white light. Since the glue is often a poor conductor of heat, the blue light is partially converted into heat energy after being absorbed by the phosphor, which will cause problems such as glue aging, reduced luminous efficiency of the phosphor after being heated, and color temperature drift. At the same time, the temperature of the LED will also rise. , shorten the service life of LED. In addition, the light emitted directly from the LED is very d...
