3. Prospect of new white LED lighting source. To illustrate the characteristics of white LED led display, take a look at the current state of the illumination light source used. Incandescent and halogen lamps led the industry, the luminous efficiency of 12 to 24 lm / W; luminous efficiency fluorescent and HID lamps from 50 to 120 lumens / watt. For white LED: In 1998, the white LED light effect only 5 lumens / watt led manufacturers, to 1999 has reached 15 lm / W, this indicator is similar to ordinary household light, and in the year 2000 led, white LED light efficiency reached 25 lm / W, this indicator is similar with halogen lamps. There predicts that in 2005, LED light efficiency up to 50 lm / W, 2015, LED light efficiency is expected to reach 150 to 200 lumens / watt. At the time of white LED current can Daan Pei-level. Thus the development of a writer with a white LED light source, may become reality. LED light source with the use of low-voltage power supply, low energy consumption, applicability, high stability, short response time, the merits of environmental pollution, and other multi-color light, although more expensive than existing lighting equipment is expensive, it is still considered inevitably replace the existing lighting devices. led- characteristic features and advantages of the LED LED inherent characteristics of the decision that it is the ideal light source to replace the traditional light source, it has a wide range of uses. led mining lamp, Hengyang led, lighting provided by Wuhan Pep Pep Lighting Limited.
