LED downlights are the primary components like housing, PCB circuit board, LED light-emitting diode. These three items constitute the main body of the LED downlight products, but also the fundamental resolution of the LED downlight product quality of the materials.
1. Housing
Shell as light mixing LED downlight product layer and protective layer, but also affect the results of LED downlight products and life. Currently used ordinary LED downlight housing is high thermal conductivity aluminum alloy shell, its anti-aging, anti-UV, impact the result is the best. Also effective steel, and slightly inferior weatherability and oxidation resistance is not high. LED downlight enclosure ordinary mask color ivory white and silver two options.
2. PCB circuit board
Circuit board as a light source LED downlight directly affect life and failure rate. LED downlight products are all electronic circuits on the PCB board, its material and processing technology will directly affect the quality and longevity. Fiberglass circuit board material is divided into full, half glass, cardboard three. LED downlight specification information shall be for the whole fiberglass double panel, such as the use of glass fiber or paperboard half after this single panel of weld quality and moisture-proof, anti-aging, and electrical properties are to a large play button head.
3. LED light-emitting diode
LED brightness is controlled by the bare core brightness LED chips and LED downlight lamp body package outline resolutions, its life is determined by the availability and quality LED chip task resolution. Here we must clarify that special, LED Downlight LED chips used in the product specification size plain as: red, yellow, 12mil, blue, green 14mil, but also effective 8-10mil chip. Differences in size of the chip can be just as shiny luminosity, but their life is completely the same, because the chip unit area greater power over the shorter its life, which is the same brightness light-emitting diode price divergent kind of reason.
