3 years after the lighting without electricity?

Solar photovoltaic, semiconductor lighting industry is about to butt two

Lighting does not plug the power supply, lighting do not need to pay the electricity bill, such a thing may not believe. But practice has proved that, to be absorbed enough heat, the solar panels and equipped with semiconductor LED (light-emitting diode two) of the lamp connected, lamps can be illuminated. This is the solar photovoltaic semiconductor lighting. Held yesterday at the "solar photovoltaic, semiconductor lighting industry docking forum, deputy director of the provincial science and Technology Department of Dongfeng Wang said, this is a key project in Wuhan city for the next 3 years, the forum held marks the project officially started. Wang Dongfeng said that the combination of light and lighting, and the invention of the electric light, like Edison, epoch-making significance.

Two major docking industry officially launched

Compared to rely on coal, nuclear power and other power generation, relying on the battery to convert thermal energy into electricity, solar power, more environmentally friendly energy. Semiconductor lighting is a semiconductor device with direct light (LED), compared with incandescent tungsten filament, without any pollution, in the same brightness, the power consumption is only 1/10 of incandescent lamp, and the service life can be 100 times longer. Wang Dongfeng said, Wuhan and the province's street lights, landscape lights, home lighting, etc., if used on this new type of lighting, will have a huge energy saving, environmental protection and economic effects. According to him, this plan has been implemented in Germany, Spain and other developed countries. But in the country, solar power, semiconductor lighting two industries are fragmented, there is no close combination. At present, only Hebei, Baoding in the implementation of the plan, the city's street lamps have adopted this new lighting. To attend the forum, not only the major enterprises, as well as from Huazhong University of Science and Technology, Wuhan University of Technology, National Laboratory of Optoelectronics and other local experts, professors. Our role is to help enterprises to study and solve technical problems. Huazhong University of Science and Technology, said Liu Minghai, universities, laboratories have set up a special group to provide technical support for enterprises. In this regard, Wang Dongfeng said that the docking of high-tech industries, to make full use of Wuhan University Science and technology resources and human resources.

3 years to achieve lighting engineering

According to reports, Hubei has nearly ten solar photovoltaic power generation companies, with semiconductor lighting products manufacturers 3, most of them are concentrated in Optics Valley. "Now the conditions are ripe for integration. "East Lake Development Zone, chief engineer Xia Yamin said that at present, solar photovoltaic companies, such as the new company, Jiawei solar battery, produced by Germany, Spain began to export. Semiconductor lighting companies, such as di source, China and other companies, the production of a variety of semiconductor chips have begun to export abroad. Whether it is the number of enterprises or technology, already have the conditions of integration". How to make the integration of the two industries docking it? Wang Dongfeng said that the current cost of the two industries are relatively high, the current price of a new lighting is about $3000 - $5000. The purpose of the forum is to come up with a solution in the near future, the development direction, reduce costs, improve technology, in the next few years, so that the lighting in any weather, lighting. Price, so that the government and the public to buy up. According to the Wuhan Jiawei photoelectric company responsible person, the core of solar power in the battery, the battery in the core of making raw materials, such as silicon, silicon layer, different raw materials, causing the battery price and electric energy conversion efficiency is not the same. In the field of solar power, enterprises, research institutions, to determine the key technical direction and direction of battery production. From the production of semiconductor lighting companies, said the production of which kind of main chip, in order to save costs and achieve the maximum lighting brightness, minimize power consumption, but also they need a unified. "We plan to make all the street lights, landscape lights, and some of the homes in Wuhan within 3 years. Wang Dongfeng confidently said that by then, the public lighting, you do not need to pay electricity bills. And Xia Yamin is more confident: Wuhan is more talented than Baoding, science and technology advantages, Optics Valley will be able to in 3 years, in the industry to become 'China's first'".
