In June 2008, Changping Town began to construct or renovate the street lights of four roads, all of which were installed as high-power LED energy-saving street lamps. Recently, the reporter visited the section of Liheng Avenue, Shijie Town, which was equipped with LED street lamps, in order to understand the application effect of LED energy-saving street lamps.
The 211-inch LED energy-saving street lamp installed in the section of Liheng Avenue in Shipai Town, the night falls, the newly installed LED street light flashes a peaceful light, and the roads of the bustling streets are beautifully dressed, the ground is evenly illuminated, and the brightness is bright. Soft, at first glance, as if a beautiful rainbow runs through the city.
How much power does it take to install such a bright light? With this question, the reporter interviewed the person in charge of the street lighting management office of Shipai Town. The person in charge said that the high-power LED street lights installed here are all purchased by Dongguan Qinshang Optoelectronics Co., Ltd. Through these months of operation, after testing, the power of 182 watts of LED street lighting is equivalent to 400 watts of high-pressure sodium lamps, the power consumption is much lower than ordinary high-pressure sodium lamps, plus line loss, the estimated power saving rate of 70 %.
Although the price of high-power LED street lamps is higher than the price of ordinary Gonna lamps, in fact, it is quite cost-effective to install high-power LED street lamps than to install ordinary high-energy lamps. The person in charge told reporters. Subsequently, he calculated the account for the reporter: If you use the high-power LED street light of Qinshang Optoelectronics to replace the 5185 street lamps in the town, you can save more than 4 million yuan in electricity a year. The saving of electric energy actually reduces or reduces the amount of coal consumption for power supply. The reduction of coal consumption and consumption of electricity supply not only reduces coal dust pollution, but also has positive environmental significance for reducing water resources waste and reducing SO2 production. In addition, the wire required for the LED lamp is fine, the copper material needs to be greatly reduced, and the transformer can also adopt a smaller specification. The advantages of the high-power LED street lamp in energy saving and environmental protection are obvious. Therefore, Shijie promoted LED energy-saving street lamps and received strong support from relevant units including the Provincial Science and Technology Department. The LED energy-saving street lamp renovation project in our town will take the lead in turning the stone platoon into a demonstration town using LED energy-saving street lamps in the province.
The reporter then interviewed Mr. Zhang Daobo, the director of the design department responsible for lighting engineering design and management of Qinshang Optoelectronics Co., Ltd. Zhang Daobo said that LED as a new concept of solid-state light source, from production process to use process until almost no pollution, with a service life of up to 50,000 hours, has become one of the most promising high-tech in the world in recent years. Qinshang Optoelectronics is committed to LED packaging and application fields, and has made major breakthroughs in high-power LED street lamps. It has obvious innovations and has obtained more than 100 international and domestic invention patents and utility model patents. Changping LEDCITY has only been carried out in Dongguan. , Shiban LEDCITY, Shilong LEDCITY comprehensive renovation project. Then, Zhang Daobo showed reporters the report on the use of high-power LED streetlights by the local street lamp management institutes such as Shilong Town and Changping Town. The report shows that the energy-saving, illumination, uniformity, safety and waterproof of the lighting circuit lights. The indicators such as dustproofing fully meet the national road lighting standards, and we are very satisfied with the 73.57% of the high-pressure sodium lamps used in the current roads.
Experts from the Guangdong LED Industry Alliance also appreciate the high-power LED products. According to the experts in charge of technical assessment of the alliance: semiconductor lighting as the most advanced new energy-saving light source, Guangdong's supporting industry chain is relatively perfect. LED is the most advanced lighting technology in the world, and is called the fourth generation light source after the light source, incandescent lamp and gas discharge lamp. LED lighting technology avoids the defects of high energy consumption, pollution and short life of the first three generations of lighting. Although it has been widely applied in the fields of backlight, decoration, display and special lighting, it is blocked in key technologies and is used in urban lighting street lamps and buildings. There has been no breakthrough in large-scale general lighting applications such as exterior lighting. As an early initiator of the Guangdong LED Industry Alliance, Qinshang Optoelectronics has been in the industry leading in the development and application of high-power LED street lamps through technical research and cooperation in production, education and research in recent years. The demonstration platform for energy conservation and emission reduction will further promote the further application of semiconductor lighting in domestic road lighting.
It is reported that in response to and implement the State Council's call for energy conservation and emission reduction, Dongguan City plans to complete the semiconductor lighting (LED) technology transformation of the city's street lamps within three years from 2007 to ease the contradiction between rapid growth in demand for electricity and tight supply of electricity. From the current statistics of Changping, Shijie, Shijie and other towns, the data statistics show that the newly installed high-power LED street lamps have obvious energy-saving and environmental protection effects. The application of Qinshang Optoelectronics high-power LED street light provides an effective way for Dongguan to complete the provincial government's target of 20% reduction in energy consumption per unit of production during the 11th Five-Year Plan period.
