A few days ago, when I saw 1500 sets of new LED energy-saving lamps and installed Tiananmen Tower as a contour light, Guo Xiaoyun, the chief engineer of Chongqing Yuanguang Electronic Technology Co., Ltd. and the State Council government subsidy, took a long sigh of relief.
On the eve of the Olympics, the Tiananmen Gate changed lights
Guo Xiaoyun said that based on the concept of the Green Olympics, the contour lights of the Tiananmen Gate Tower were also required to be replaced with new environmentally-friendly and energy-saving lamps on the eve of the Olympic Games. Chongqing Yuanguang Electronic Technology Co., Ltd. also received the task of developing new energy-saving light sources. At the same time, not only Chongqing and domestic enterprises, but also many big names in the international lighting industry are involved in the competition. The competition is fierce.
At present, many energy-saving lamps in the world have a lifespan of only 8,000 hours, and the luminous efficiency is only about 50%. Tiananmen Contour Light The basic requirement for this lamp replacement is that it will not be replaced for at least 3 years, and it is required to be energy efficient. In addition, the normal voltage is generally 220 volts, and the voltage of the Tiananmen contour light is between 240 and 260 volts, so the power supply requirements are very demanding. Guo Xiaoyun said that after half a year of hard work, the new LED light source bulb DHLEDQ60-3 was finally developed.
Power meter size, with a magnifying glass to weld
Guo Xiaoyun revealed that the new LED light source developed, in addition to the chip is the technology of the US GYEE company, the rest are self-designed.
Don't underestimate this small light bulb, the technology content is very high, just take the power supply, the power of the lamp is only the size of the rice grain, the technician must be welded on the magnifying glass. Guo Xiaoyun said that the new product not only has a life span of 100,000 hours, but also has very low energy consumption. The 3 watt DHLEDQ60-3 can emit 60 watts of light from a conventional bulb.
Guo Xiaoyun said that after rigorous testing, DHLEDQ60-3 reached the requirements of the Tiananmen Tower's contour lights. PK lost its competitors, boarded the Tiananmen Gate Tower, and completed the installation last week.
The energy efficiency of this kind of lamp is more than 90%. If it is promoted into the family nationwide, the annual energy saved is equivalent to the annual power generation of the Three Gorges Project. Guo Xiaoyun said, however, the current lamp has not been mass-produced, and the cost is still relatively high. It should be 2-3 years after entering the ordinary family.
Made in Chongqing, the first Tiananmen Gate
In addition to the Tiananmen Contour Light, the underwater lights of the Tiananmen Square fountain and some Olympic venues have used the light source made in Chongqing. Deng Luguo, chairman of Chongqing Yuanguang Electronic Technology Co., Ltd. said.
Deng Luguo said that although the company's high-efficiency underwater lights have entered key buildings such as Tiananmen Square since 1998, it is the first time to board the Tiananmen Gate as a contour light.
