If 50% of the country's light sources use LEDs, the annual electricity consumption is equivalent to the construction of 2.5 Three Gorges power stations. On the 3rd in the 2012 Optoelectronics Industry and Investment and Financing Cooperation Forum held in Wuhan, many experts in the field of optoelectronics are optimistic about the development prospects of LED lighting.
LED is a new type of light source that uses a semiconductor chip to emit light, and its greatest advantage lies in energy saving. Under the idea of ​​building a low-carbon economy in China, energy-saving and environmentally-friendly LED lighting is increasingly favored by the public.
Chen Hongda, deputy director of the Institute of Semiconductors of the Chinese Academy of Sciences, said that if 50% of China's light sources are replaced by LEDs, it will achieve an annual power saving of 210 billion kWh, equivalent to the construction of 2.5 Three Gorges Project. At the same time, LEDs have incomparable advantages in terms of life and application flexibility.
However, from the current stage, the popularity of LED lighting is still not high, and the biggest problem is cost. Li Ke, director of the Information Exchange Department of the China Semiconductor Industry Association, said that the current cost of LED lighting is about 3-5 times that of ordinary light sources.
However, with the advancement of technology, the cost of light sources and components is declining, and the market share of LEDs is also growing steadily. According to statistics from CCID Consulting, a well-known industry consulting firm, the size of China's LED lighting market in 2011 was 21.14 billion yuan, a year-on-year increase of 32.6%.
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 12th Five-Year Plan for Semiconductor Lighting. It is proposed that by 2015, the share of semiconductor lighting in the general lighting market will reach 30%; from October, China has banned the import and sale of more than 100 watts of incandescent lamps. The industry expects that in the next few years, China's LED lighting market will usher in the peak period of development, the market demand is expected to exceed 100 billion, and the market share will reach more than 30%.
