Abstract

The invention discloses an LED fluorescent powder coating technology. An aluminium alloy surface is used as a reflection surface of an LED light source. The aluminium alloy is processed by surface treatment, and the surface treatment comprises aluminium alloy anodic oxidation treatment, nanometer fluorescent powder surface finish processing, nanometer fluorescent powder filling processing and hole sealing processing. The aluminium alloy surface is used as the reflection surface and partly converts blue light emitted by an LED to yellow light through conversion effect of the nanometer fluorescent powders. The yellow light and the blue light are mixed and become white light. Technical effects of the technology are that the fluorescent powders are no longer obstacles of LED heat radiation, and meanwhile the fluorescent powders would not work under relatively high temperature. The technology is an optimal technical scheme for an ultra high 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. [0003] Therefore, a new LED phosphor coating method is p...
