The LED lamp power and "longevity" because the price is too high to enter people's homes

The streets of Shanghai frequently appeared a new light source - LED lamp, the lamp filament lamp is not with "old face", it is the use of mobile electronic luminous, directly converts electrical energy into light energy conversion efficiency as high as 68%, is 5 times more than incandescent lamp. It is reported that LED's power consumption is only 100 of the traditional light bulb, the service life is the latter of the 1/10. LED lamp without loss of heat energy, electric energy conversion efficiency is much higher than ordinary light bulbs, but why is hard for people?

Yesterday, according to information provided by the Shanghai semiconductor lighting engineering research center, Shanghai's total electricity consumption of 12 ~ 15% of lighting electricity, if the use of LED lighting to replace the bulb, it can save about 70%. Ordinary incandescent lamp power is 40 ~ 60W, and the LED lamp is only 3 ~ 6W, and the life span to 30 thousand ~ 50 thousand hours, although the global LED lighting price expensive than ordinary light, but these additional costs will be 3 ~ 5 years back.

It is estimated that if the Shanghai resident population of nearly 8 million of the use of LED to replace the traditional lighting, which is expected to save every year at the time of the provincial capital of 1 billion kwh of electricity, equivalent to a small city in a year's total electricity consumption.

The new light source such why hard people? Recently, this reporter visited a number of places of sale, sales and marketing staff told reporters that the current market LED light source is generally sold in accordance with the power, the greater the power, the higher the price. At present, the highest price of LED million, the biggest reason perhaps this is why the LED lamp has hard for people at home.
