LED R & D promotion need time when China bid farewell to the era of Edison"

In 1879, Edison invented the incandescent lamp, human beings have entered into the electricity to replace the fire lighting, "the era of Edison". But by twenty-first Century, people were trying to say goodbye to the incandescent lamp. In July 1st this year, is Zhejiang County of Pujiang province in the detection of LED Products Co. Ltd. Hangzhou Dianzi University senior engineer told Luo friends of "market Herald" reporter, since 2007, North America and Australia are legislation prohibiting the use of incandescent lamps. In the spring of 2007, the European Union reached an agreement to ask the EU countries to phase out incandescent lamps and replace them with rare earth energy-saving fluorescent lamps. It can be said that the elimination of incandescent lamps in the global scope, promote the use of rare earth energy-saving fluorescent lamp. 2007 is known as an epoch-making "rare earth green" next year".

This means that human society began to bid farewell to the Edison era".

"Farewell" is based on the fact that the global energy crisis. Provides the basis and the birth of LED -- light emitting diode for "farewell": LED is used as a new energy efficient lighting luminescent materials using solid semiconductor chip, the birth of LED is called the human source of the third revolution after the fire, the electric light bulb.

When will China bid farewell to the "Edison era"?

Director, Zhejiang Comprehensive Energy Technology Supervision Corps Department Senior Engineer Wang Yunpeng said, LED in China is being extended to the city landscape, commercial large screen, traffic lights, mobile phone, computer and other fields, such as street advertisement lamp high-power LED lighting is also in the promotion of.

Luo friends said that China is a major producer of energy-saving lamps, but it is a small country. Although Zhejiang is the world's largest energy-saving lamp production base, the output accounted for about 50% of the world, but Zhejiang's energy-saving lamps for export 95%. LED as a more advanced than energy-saving lamps, its products are basically sold abroad.

Star general manager Xue Wenyan for our bill: a 250 Watt sodium lamp light source part as long as 220 yuan, annual electricity to 1577 degrees, according to the general public price calculation, electricity 946 yuan; a light source part of LED street lamp is corresponding to 1700 yuan, but only 525 years of electricity, electricity fee only 315 yuan, 1 years can save electricity 631 yuan; sodium 9 -12 months to be replaced once, LED is available in 3-5. According to 2 years as a cycle, the total cost of the traditional light source of $2332; LED street lamp 2330 yuan, the cost can be recovered in 2 years, the overall investment will not be too expensive, energy saving and environmental protection, obvious advantages.

Luo said that China is the world's first producer of lighting appliances, the second largest exporter. In 2003 the establishment of the national LED lighting project coordination leading group, officially launched the national LED lighting project. But the reality is not optimistic, China's economically developed areas of the city about 70% users to enable energy-saving lamps, rural and underdeveloped areas still use incandescent 80%, LED has just started.

He believes that LED research and development and promotion will take time. The Ministry of Finance in 2008 began to implement the "efficient lighting products to promote financial subsidies to fund management Interim Measures" have been included in the semiconductor (LED) lighting products LED lighting products, but there is no complete national standard.

China bid farewell to the Edison era long way to go, there is still a long way to go.
