LED lighting large-scale applications can save hundreds of billions of degrees per year

Recently, the Ministry of science and technology joint housing and urban construction department in Guangzhou city held a "ten city lights" pilot work of semiconductor lighting spot. Vice Minister of the Ministry of housing and urban construction and housing and urban construction department on behalf of Qiu Bao mainly expounds the following three aspects: one is the prospect and potential for the promotion of LED lighting; two is the main approach of early promotion of LED lighting construction; three is to accelerate the basic LED to promote the next step.

First, the promotion of LED lighting energy saving potential

Mainly in 3 aspects.

Application of 1.LED in urban lighting. If only consider the city's 657 municipal lighting (excluding about 2000 counties and about 20 thousand small towns) of municipal road lamps have a total of 17 million 740 thousand, a huge number of landscape lighting. As China is in a period of rapid urbanization, urban population increased by about 10000000 per year, street lamps will grow by an annual rate of 120 - 1 million 500 thousand, and this process will continue for 25 years or even years. If the city's new street lights using LED, part of the old lights and landscape lighting to LED lighting, which the potential and development prospects can be imagined.

2 residential buildings in the promotion of LED lighting. China is a big country construction industry, the annual new construction of 2 billion square meters, equivalent to half of the world's new building in China, each construction unit must be at least 20 lights; plus the "12th Five-Year" period, the government money to build low-income housing 36 million sets, the potential applications of this there will be 5 - 600 million LED lights. In the city has built a construction area of about 20000000000 square meters, according to expert estimates, if the use of LED lighting, you can save about 100000000000 kwh of electricity. Compared with other energy-saving projects, the potential of the LED lamp is very large, such as the national motor 50% to high efficiency motor, it can save energy of 3 billion 400 million degrees, this is because the motor energy saving on the amazing 10%. But LED replace the traditional incandescent lamp can save more than 50%.

3 broad rural market potential is greater. At present, the most urgent is that there are nearly about 20000000 farmers lack electricity, if these farmers use solar energy and LED integration, replacing the large power grid, the annual savings of electricity will be about 50000000000 degrees. Such as the use of traditional large power grid extends to these remote villages, not only 75% of the electricity consumption will be on the road, and its maintenance costs are extremely high, with a total investment of more than 50 billion yuan. Household solar photovoltaic and LED lighting integrated facilities, only 1600 yuan per household can solve the lighting problem, and maintenance costs are very low. Coupled with nearly half of China's urbanization population of about 20 thousand small towns, to promote the huge capacity of the LED market. Thus, LED promotion is undoubtedly one of the main battlefield of China's energy conservation and emission reduction.
