LED light source 1. High luminous efficiency, small power consumption, long service life, low working temperature. 2. Strong safety and reliability. 3. Quick reaction speed, small unit size, green environment. 4. Under the same brightness, power consumption is one-tenth of incandescent lamp, one-third of fluorescent lamps, while life is 50 times times of incandescent lamp, 20 times times of fluorescent lamp, it is the fourth generation lighting product after incandescent lamp, fluorescent lamp, gas discharge lamp. 5. The advent of a single high-power super brightness led, is the LED application of the field across to the high efficiency lighting market becomes possible, will be the man after Edison invented the greatest invention of incandescent.
