In the light of the electronic giant single LED light money"

With Zhang Yanwei out of the new in Shandong high tech Industrial Development Zone of Weifang office building face at the park lights, the mysterious smile. Maybe he only inside the company employees understand this meaning smile. On this day, as Zhang Yanwei, senior vice president of China Light Electronics (Weifang) Co., Ltd. has just signed a contract with Weifang hi tech innovation park construction office. In accordance with the contract, 144 large solar power high brightness light-emitting diode (LED)

Street lights will illuminate the entire park. Actually, half a year ago, in the "returnees" team has successfully overcome the application of high-power LED on road lighting international problem, developed the world's first 100 watt LED lamp lighting system. But the patent vigorously promoted in the hand of the core technology they did not rush, has been testing constantly, is also waiting for a blockbuster, major inroads into the market opportunities.

"I am now the identity of the merchant, for businessmen, the timing is very important, this half year we have put it in the palm of your hand, and now is the time to fully open, and the final success is correct." Zhang Yanwei said. The United States Department of electronic engineering, New Jersey Polytechnic University, a visiting scholar at the Princeton University, although also maintained a strong pedantic, as in the past the refined manners, but apparently has entered into the new role of the market.

In the micro plan, they want to put on each side of China's newly built roads on this side of the power consumption is very low, soft light, uniform distribution of light field of magic lights.

Light "money"

A small light-emitting diode (LED) for the micro lit the money".

This sounds quite professional terms in our lives can be seen everywhere, electrical lights, cell phone backlight, traffic lights on the road. Ten years ago, the light-emitting diode applied to lighting lighting industry began to rise, but has been plagued by two major technical problems: one is the photoelectric conversion efficiency is too low, even ordinary incandescent light bulbs are not up to the brightness, most can be used as toys and power up to two is excuse me at night; to a certain amount, the heat problem it is difficult to solve, prior to the International LED lamp is only 70 watts maximum power.

Independent intellectual property rights, the core technology is a high-tech enterprises to open the market, a sharp knife". This year just a year and a half has been in the micro knife".

By a number of doctoral team composed of less than a year to create 5 patents, out of the top two technical difficulties. The lamp power LED they developed a record of 100 watts, 14 meters above the average illuminance on the poles reached above 15 lux, exceeding the national standard; also do light field and light intensity control lighting, street lamps are humanized "which according to which". Such lighting system can work for 100 thousand hours continuously, life is 10~20 times the traditional street lamp, power consumption is less than the traditional street lamp of 20%.

In the micro solar LED street lamp system has been put into trial in Weifang high tech park. This kind of street lamp no longer forms the circular light field of the traditional street lamp, and becomes the rectangle, the light field distribution is even, the light is soft, is like to the road paved with each one "the light blanket".

Medium and small back to these street lights installed a hat - Solar panels. During the day, solar energy is collected and stored in a rechargeable battery through a solar panel, and the stored electric energy is released when the light is dark at night to drive the LED street lamp to shine. This "saved" simply become a street without additional power supply, without laying cable energy specialist.

Zhang Yanwei calculate a bill, the national annual Street electricity is about 6 billion yuan. If all the use of LED street lamps, saving nearly 5 billion yuan per year.

The cost of the initial investment of LED street lamp is higher than that of the traditional street lamp, but there is no other expenditure after a one-time investment. Our market is right here." Zhang Yanwei is confident.

Serendipitously

In fact, we initially envisaged the main product is the optoelectronic chip, lighting applications have been feeling small, the original did not pay too much attention, and now it seems that the rapid development of LED street lights." Zhang Yanwei often feel that this is a bit careless Liu Liu liu.

Zhang Yanwei is one of the founders of the micro, but also one of the high-power LED street lighting system developers.

By the end of 2003, the United States has been returned to the United States Zhang Yanwei thirteen years away from his native land, and he came back, and there are the same experience with him, he shared the same professional background of dr.. Previously, they resigned from the positions of ST microelectronics, Motorola, JDSU and other companies, three people have the same goal in mind - the creation of a company of its own optical information technology.

This time, the United States optoelectronics, semiconductor industry has entered a period of rapid development of the platform, is facing the third transfer, and China is one of the direction of transfer.

"The biggest advantage is the staff. The development of the photoelectron industry in China is very fast, and there are a number of mature technical personnel, the labor price is very good, the quality of workers is also good." After some analysis, they believe that all aspects of the conditions are ripe.

"The products produced in China don't have to worry too much, and the cost is lower in Shandong than in other parts of china." After a comparison, Zhang Yanwei
