Little photoelectric tube (Wei workshop) in China It is a central Hi-Tech trans-corporation that limited company produces the semi-conductive light source device, this company has put out a series of world-leading high-quality high-power LED street lamp products with the independent intellectual property right, this kind of street lamp is average and accident-free in 50000 hours, starting time is less than 50ms, the starting current is small, power efficiency is greater than 90%, have unique lighting optic path design, there are no light pollution, glare phenomenon, non-stroboscopic. This kind of street lamp energy-efficient, green environment protective, reliability is high, light distribution is rational, promote the urban image. In 2008, will sell and install 50,000 outside China.

The city of Wei workshop would install 20,000 in the urban area successively in 2008, economized on electricity by 12 million degrees that year, saved the electric rate of 9 million yuan. Have already installed this kind of 30,000 street lamps at present in Wei workshop, has basically realized and covered completely, the city of Wei workshop becomes the first LED city in the world too.

The municipal urban construction bureau of high and new technology industrial development zone of Wei workshop has something to do and responsible for being called, the little LED street lamp if in 300,000 traditional street lamps are all used instead, will save about 440 million degrees of electricity consumption every year, save 176,000 tons of coals, save 1,760 million liters of water purification, reduce 120,000 tons of dust emission, reduce the carbon dioxide and discharge 439,000 tons, reduce sulfur dioxide 13,000 tons of discharge, save the maintenance charge of about 210 million yuan every year on average.

If the newly-built road adopts LED street lamp, then, installs 10,000 street lamps each time, can save the expenditure of about 28 million yuan of the copper cable, save about 14,800,000 voltage transformer invest, meanwhile, can save 70% more than electric rate, save the electric rate of about 14,460,000 yuan every year, save the maintenance cost of 7 million yuan.
