LED downlight power life decisions are mainly three parts:

LED lamp, LED cooling "shell design", LED power supply.

LED lamp manufacturers determine the major life LED downlight power, the current foreign chip manufacturers have high quality American CREE, Japan's Nichia (Nichia), etc., cost-effective manufacturer Epistar Taiwan (in Chinese refers to the purchase of Epistar LED chip take the product packaging, and many more on both sides of the Taiwan factory or packaging factory in China producing mainly), Everlight, etc., mainland manufacturers have three safety optoelectronics, Yingrui optoelectronics.

General quality LED downlight power supply manufacturers, will use foreign as Cree LED chip, at least recognized as one of the high stability of the product on the market. Such natural light made ​​of high brightness, long life, but the price is not cheap, using Taiwan manufacturers of chip life is long, but the price is relatively low, basically acceptable to the Chinese domestic market customers. Chinese domestic market chip short life, the light fades larger, but the price is the lowest number of small manufacturers fight to become the first choice for the price. What kind of LED lamp uses, LED chips, LED downlight also directly determines the positioning and power supply manufacturers in the industry has shown social responsibility.
