LED power saving can reach 2.5 seats of the Three Gorges

If 50% of the country’s light sources use LEDs, the annual savings will be equal to the construction of 2.5 Three Gorges power stations. At the 2012 Photovoltaic Industry and Investment and Financing Cooperation Forum held in Wuhan on November 3, a number of experts in the field of optoelectronics were optimistic about the development prospects of LED lighting.

LED is a new type of light source that utilizes semiconductor chips to emit light. Its greatest advantage lies in its energy saving. With the idea of ​​building a low-carbon economy in China, energy-saving and environmental-friendly LED lighting has become more and more popular. Chen Hongda, deputy director of the Institute of Semiconductors at the Chinese Academy of Sciences, said that if 50% of China's light sources are switched to LEDs, it will be able to save 210 billion kwh per year, equivalent to the construction of 2.5 Three Gorges Projects. At the same time, LEDs have unparalleled advantages in terms of life span, application flexibility, and so on.

"But from the current stage, the popularity of LED lighting is still not high, the biggest problem is the cost." Li Ke, director of the Information Industry Department of the China Semiconductor Industry Association, said that the current cost of LED lighting is about 3-5 times the average light source. However, with the advancement of technology, the cost of light sources and components is declining, and the market share of LED is also steadily increasing. According to statistics from CCID Consulting, a well-known industry consultancy, China's LED lighting market in 2011 was 21.14 billion yuan, an increase of 32.6% year-on-year.

At present, China has formulated relevant policies to further promote the large-scale development of the LED market. In August this year, the Ministry of Science and Technology released the “Twelfth Five-Year Plan” for semiconductor lighting, and proposed that by 2015, the share of semiconductor lighting in the general lighting market should reach 30%. Since October, China has banned the import and sale of incandescent lamps of more than 100 watts. The industry expects that in the next few years, China's LED lighting market will usher in the peak period of development, and the market demand is expected to exceed 100 billion, with a market share of more than 30%.
