In 1900, Peter Cooper invented the fluorescent light with light efficiency of 70 LPW. While now white light LED can reach over 300 LPW because white light LED is based on blue light LED with high brightness. The blue light can activate phosphorus to convert itself into white light. These LED with high quality can reach a life span as long as 100,000 hours. In comparison, the life span of fluorescent light is one tens of it and that of incandescent light is one hundreds of it. The cost for white light LED is gradually decreasing, so the LED Tri-proof Light market is quickly expanding. In the near future, triple color LED may replace the combination of blue light LED and phosphorus. It may be used in high brightness lighting and may allow us to dynamically control the color composition. We can already see all kinds of novel LED Lights colors in LED Lighting market, such as light green and pink.Besides, lighting consumes 20 to 30 percent of global electricity, and the energy consumption of new white LED is only one tens that of normal bulbs, so white light LED can save a lot of energy for humans. Besides, LED lights can be used as long as 100,000 hours, comparing with 1,000 hours for incandescent lamp s and 10,000 hours for fluorescent lights, LED also helps to save materials.
