LED lighting in the end how much can be saved?

LED lighting cost-effective? The transformation of investment funds and benefits? This is the market for LED can promote the most worried about the scale of the problem.

The LED lamp KingSun 100W as an example, a year ago to purchase LED street for the cost of 2500 to 3000 yuan, the street price dropped to 1500 yuan, 1800 yuan, 1200 yuan to replace the 800 - high pressure sodium return period is reduced to 2 - 3 years. The LED street lamp energy saving 50%, life of up to 9 years, during the lamp does not need to be replaced. New street lamps using LED cost-effective has been very obvious.

On the transformation of LED lamp replacement funds raised in Guangdong to promote the use of LED lighting products "implementation plan", local governments will solve the LED lighting renovation project funding from the city public utilities with additional income levied in electricity.

According to the data of LED demonstration project in the past two years, the Guangdong Provincial Department of science and technology has calculated the economic benefits and the effect of energy saving and emission reduction of the LED street lamp renovation project.

In accordance with the 2 million LED street lamps to calculate, before the transformation, the annual price of electricity to reach 2 billion yuan street lamps, lamps and lanterns replacement costs up to $500 million per year, so that the total annual cost of $2 billion 500 million. After the transformation, the annual total cost savings of 1 billion 500 million yuan, including the cost of electricity savings of $500 million and a replacement fee of $50%.

2 million LED street lamp renovation of a total investment of 4 billion 890 million yuan, plus a total loan interest rate of a total of $6 billion 100 million. In the LED street lamp life of 9 years, a total savings of $13 billion 500 million, the local government to obtain energy savings of $7 billion 400 million.

In addition, will save 10 billion 800 million kwh of electricity, equivalent to saving the standard coal of 3 million 790 thousand tons, reducing sulfur dioxide emissions by 70 thousand tons, reducing carbon dioxide emissions by up to 2 million 680 thousand tons, reducing soot emissions by 70 thousand tons.

It can be seen from the tariff levied by the city's public utilities in addition to the proportion of energy extraction efficiency, can pay for the transformation of LED investment, and can produce significant economic benefits and energy-saving emission reduction effect. Guangdong science and technology department director Li Xinghua said.
