LED lamp power saving and high cost of life has become a bottleneck

As a new lighting technology, LED because of its energy saving, environmental protection, long life, fast start and other characteristics are generally optimistic. However, behind the scenery is lonely, at present, more than 90% of the enterprises in Jiangsu LED products exported overseas, in Nanjing, only the use of LED model street tunnel.

When will LED get out of loneliness? In yesterday's 2009 annual meeting of the association of Nanjing City, the development and application of LED technology branch, industry experts pointed out that with the progress of technology, LED will eventually be out of the praised circle.

If the full use of LED lights, a year saving more than 100 million degrees

Yesterday afternoon, the reporter saw in the model of the road tunnel, both sides of the tunnel embedded on numerous light bean sized beads, clean and beautiful, and the light will change with the external solar light intensity, air vents near the LED brightness is relatively low. The entire tunnel light.

The tunnel is the use of intelligent LED product development in Nanjing Henderson Polytron Technologies Inc. The company's executive vice president Yang Haifeng told reporters that these lamps used in the tunnel for a whole year, more than and 900 sets of lamps and lanterns without any damage to the more than 50 thousand LED, more than the current use of high-pressure sodium lamp power saving of more than 50%. At present, the company is also Liuhe Longchi lake to build a "complementary" characteristic demonstration Road, 100 LED road lamps as long as a blow to bask in the sun, the evening will be bright.

According to reports, LED lamp life of up to 6-10 hours. Deputy Secretary General of the Provincial Institute of electronics Xu Chengyuan calculations, Nanjing existing more than 160 thousand high-pressure sodium lamp, in terms of each street lamp power consumption per hour of 0.5 degrees, the city's street lighting power consumption of about 320 million degrees. If all the LED street lamp, at least 160 million degrees of electricity saving, coal saving more than 50 million tons.

High cost has become a bottleneck

To achieve the same brightness, the LED lamp is at least 85% times longer than that of the incandescent lamp, and the service life is longer than 40 times. Compared with the fluorescent lamp, the LED lamp saves electricity by a factor of 50%, and the service life is longer than 10 times. LED can not be generalized to promote the application.

A LED product promotion will be held in Shanxi on the road in front of the square, LED lamps display rich and colorful, flashlights, lamps and other lighting Goods are available in all varieties. The same day more than 1000 people received a brochure of science, but eventually sold only a small amount of LED flashlight and a LED bulb. Some people said that a LED lamp 300 yuan, is five or six times the ordinary lamp, saving money back, "don't know god knows how long."!

Yang Haifeng admitted: because of the use of high-performance LED chips to be imported from abroad, a LED lamp at least 20 yuan, while ordinary bulbs as long as $1. LED in order to really expand the market, reduce costs, we must start from the technology. Xu Chengyuan analysis, Jiangsu LED has formed a complete industrial chain, many companies are conducting technical research, made a number of technological breakthroughs. How to effectively integrate the enterprises, universities, research institutes, and focus on the core technology of joint technical research, LED industry is an urgent problem to be solved.

Nanjing will be selected through the experiment to promote quality products

Some manufacturers claim their products for up to 50 thousand hours, up to 100 thousand hours, but the quality of the product really, we can not grasp. "City Street Management Office official said, Nanjing has been in the west of Taishan road and Xianlin Jiuxiang river area construction of a road test, the selection of 10 scale enterprises producing brand products of PK, through specific experiments to obtain reliable data, the selection of brand promotion will eventually have a good mastery of the product quality.

It is reported that the national development and Reform Commission, Ministry of science and technology and other 6 departments recently jointly announced the development of semiconductor lighting industry views of energy efficiency requirements for the 2015 LED product functional lighting reached about 20%. Xu Chengyuan suggested: Jiangsu and Nanjing can take the first step, requiring major infrastructure projects and public utilities projects to achieve a certain proportion of LED lighting products, open LED lighting products market.
