The main reasons determine the lifespan of LED downlights have three parts: LED lamp beads, led heat "shell design" and led power supply. LED lamp bead manufacturers determine the major life LED downlight. Currently, the top foreign chip manufacturers are American CREE, Japan's Nichia (Nichia), Citizen, and so on.

General quality LED downlight manufacturers will use foreign CREE LED chips, at least recognized as one of the high stability products on the market. Such natural light is 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 mid-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 manufacturers in the industry have shown social responsibility.

LED Power LED downlight is the heart of a great impact on the life of LED downlights. In general, LED downlights have a 110 / 220V power supply, China's domestic market is a 220V power supply. Because of the shorter development time LED lights, the state has not addressed its standard power supply LED power supply on the market so uneven, ring-like phenomena, a large number of low-PF value, simply can not supply the market is flooded by EMC. Power electrolytic capacitor life also directly determines the power of life, as everyone on the price-sensitive, ways to reduce the cost of power, resulting in low power LED power conversion, life is not long to make LED Downlight from "longevity light" to a "short-lived lights.

The cooling design of LED downlights influences their lifespan. Started from LED lamp beads, then the heat is conducted to the internal PCB and then exported to the shell. The shell gives out heat by convection or conduction to the air. PCB to heat fast enough, thermal performance thermal grease to be good enough, enclosure cooling area should be large enough, the rational design of several factors determines the LED lights work properly when the PN junction temperature is not higher than 65 degrees, in order to ensure LED the chip is in normal operating temperature because the temperature is too high and not too fast to produce the light fades. best led headlights http://bestledheadlight.com/
