 LED as a new type of light source, energy saving, long life, clean by all the attention. In particular, China Olympics, successful use of a large number of LED technology, the effect is extraordinary, local governments have to support the LED industry, the establishment of a l arge number of LED demonstration unit. However, due to the more expensive, few people interested.

      The same power, ie, the wattage is the same energy-efficient light than ordinary energy-saving lamps bright. In theory, the ordinary energy-saving lamp life of approximately 5000 hours, indoor LED lamp life of up to 50,000 hours. In theory, the calculation of electricity per day 5 hours, it s life up to 27 years.

 

  LED energy-saving lamps will carry out the reform to break through the price barrier

        Normal wear and tear and glow the same premise, can choose the ordinary energy-saving in straight fluorescent lamps (15W) and equal to its glow LED lamps (9W). At present, an energy-saving lamps sell for about 50 yuan, the LED lamp is priced at 200 yuan. 50,000 hours of work time and residents of Harbin City, electricity (0.51 yuan / kWh) calculated the electricity of ordinary energy-saving lamps to 382.5 yuan (15 watts x 50000 hours) / 1000 × 0.51 = 382.5; the LED lights with The power cost of 229.5 yuan (9 watts x 50,000 hours) / 1000 × 0.51 = 229.5. In 50,000 hours of testing, however, ordinary energy-saving lamps, 10 lamps need to be replaced. Assume that a $ 50 general energy-saving lamps, including lamps fee of 25 yuan and 25 yuan lamp fee, then ignited the 50,000 hours cost $ 275 (25 × 10 tube +25 $ = 275); and lit 50,000 hours LED lights only need one, cost about 200 yuan. Ordinary energy-saving lamps lit simultaneously by 50,000 hours, spent 657.5 yuan, LED lights, compared with 429.5 yuan. Seen in this light, an LED light than ordinary energy-saving lamps save 228 yuan. Each room lights total, the cost of the savings will be doubled.
