Abstract

The invention discloses an LED fluorescent powder coating technology. An aluminum alloy surface is taken as a diffuse reflection surface of an LED light source; aluminum alloy is subjected to surface treatment; the surface treatment comprises aluminum alloy anodic oxidation treatment, nano fluorescent powder surface finish treatment, nano fluorescent powder filling treatment and hole sealing treatment; the aluminum alloy surface is taken as the diffuse reflection surface and partially converts blue light emitted by an LED into yellow light through the conversion function of nano fluorescent powder, and the yellow light and the blue light are mixed to form white light. The LED fluorescent powder coating technology has the technical benefits as follows: the fluorescent powder doesn't block radiating of the LED, simultaneously, work of the fluorescent powder at higher temperature can be avoided, and the LED coating technology is a preferable technical scheme of a superhigh power LED light source.

Description

technical field [0001] The invention belongs to the technical field of LED lighting, and in particular relates to an LED fluorescent powder coating technology. 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 ve...
