LED light source price is high and difficult to enter ordinary people's home
There is a new light source in the streets of Shanghai - LED lights, which are not the "old faces" of filaments and light bulbs. They use electronic movement to illuminate and directly convert electrical energy into light energy. The conversion efficiency is as high as 68%. It is an incandescent lamp. More than 5 times. It is reported that the power consumption of LED is only 1/10 of the traditional light bulb, and the service life is 100 times that of the latter. LED lights have no heat loss, and the power conversion efficiency is much higher than ordinary light bulbs. But why is it difficult to enter the home?
According to the information provided by the Shanghai Semiconductor Lighting Engineering Technology Research Center yesterday, 12 to 15% of the total electricity consumption in Shanghai is lighting power. If LED lighting is used instead of the light bulb, it can save about 70%. Ordinary incandescent lamp power is generally 40 ~ 60W, while LED lights only need 3 ~ 6W, and can extend the life to 30,000 ~ 50,000 hours, although the price of LED lighting equipment is more expensive than ordinary light bulbs, but these additional costs will be Come back in 3 to 5 years.
It is estimated that if nearly 800 million permanent residents of Shencheng use LEDs instead of traditional lighting, then Shencheng is expected to save 1 billion kilowatt-hours of electricity per year, equivalent to the total amount of lighting used in a small and medium-sized city for one year.
Why is this new energy-saving light source difficult to enter the home? Recently, reporters visited some sales venues for this purpose. Market sales personnel told reporters that the current LED light source on the market is generally sold according to power. The higher the power, the higher the unit price. At present, the highest price of LED is 10,000 yuan, which may be the biggest reason why LED lights are difficult to enter the people's home.
