Chongqing: victory over the world's largest Tiananmen tower

The day before, when you see the 1500 sets of new LED energy-saving lamps, installed on the Tiananmen gate as a contour lamp is lit, the chief engineer, the source of Chongqing Optoelectronic Technology Co. Ltd. the government of the State Council allowance winner Guo Xiaoyun relieved.

On the eve of the Olympic Games, Tiananmen

Guo Xiaoyun said, based on the concept of Green Olympics, Tiananmen square, contour lights are also required in the eve of the Olympic Games for the new environmentally friendly energy-saving lamps, and the source of Chongqing Photoelectron Technology Co Ltd also received the development of a new energy-saving light source task. At the same time to participate in the project competition not only Chongqing and domestic enterprises, as well as many of the major international lighting industry, the competition is very fierce. "

At present, many of the world's energy-saving lamp life only more than 8 thousand hours, only about 50% light efficiency. Tiananmen outline lamp for the basic requirements of the lamp is no longer replaced at least 3 years, and requires efficient energy saving. In addition, the general voltage is generally 220 volts, while the voltage of the Tiananmen contour lamp between 240-260 volts, so the power requirements are very harsh. Guo Xiaoyun said, after six months of efforts, and finally developed a new LED light bulb - DHLEDQ60-3. "

Power supply size can be welded with a magnifying glass

Guo Xiaoyun said, the development of a new LED light source, in addition to the chip is the use of the United States GYEE company's technology, the rest are independent design. "

Do not underestimate this small bulb, high technology content, take the power supply, the power supply is only the size of the rice, the technical staff to be able to weld on the magnifying glass. Guo Xiaoyun said, the new product is not only reached 100 thousand hours of life, and energy consumption is very low, the DHLEDQ60-3 can be issued to the traditional 3 watt light bulb. "

Guo Xiaoyun said, after a rigorous test, DHLEDQ60-3 reached the Tiananmen tower outline lamp requirements, PK lost competitors, boarded the Tiananmen tower, and last week to complete the installation.

"The energy efficiency of this lamp is more than 90%, if the national promotion into the family, the annual energy savings equivalent to the Three Gorges project a year of electricity generation. Guo Xiaoyun said, but now there is no mass production of this lamp, the cost is still relatively high, into the average family should be 2-3 years later. "
