Road efficient lighting promotion LED market share continues to expand


LED market share will continue to grow, but lighting products including ceramic metal halide lamps will still have vitality. Chen Yansheng, vice chairman and secretary general of China Lighting Association, said at the application promotion conference of high-efficiency lighting and energy-saving technology for ceramic metal halide lamps sponsored by Beijing Energy Conservation and Environmental Protection Center not long ago that traditional high-efficiency lighting products will coexist with LEDs for a long time. . At present, ceramic metal halide lamps are still a hot spot in the research of international electric light sources. He suggested that while government departments pay attention to the development of LED, do not easily give up the promotion of other high-efficiency lighting products.
The Beijing Energy Conservation and Environmental Protection Center's high-efficiency lighting and energy-saving technology application promotion project is one of the sub-projects of China's phasing out of incandescent lamps and accelerating the promotion of energy-saving lamps by the National Development and Reform Commission, the United Nations Development Program, and the Global Environment Facility. The project targets the application of high-efficiency lighting products and organizes special promotion activities in different fields. The promotion conference of high-efficiency lighting and energy-saving technology for ceramic metal halide lamps held this time is one of many high-efficiency lighting product promotion conferences. The convening of the application conference of high-efficiency lighting and energy-saving technology for ceramic metal halide lamps marks that ceramic metal halide lamps have entered the stage of mature technology and large-scale application as high-efficiency energy-saving electric light sources. The ceramic metal halide lamps are in different fields such as roads, industries and commerce. The application will be of great significance.
The ceramic metal halide lamp is called the Prince Charming in the electric light source. It has broad application prospects in the field of commercial lighting and road lighting. The 11th and 12th Five-Year Plan has been listed as a key research and introduction project by the National Development and Reform Commission and other relevant departments. . The "China Medium and Long-Term Energy Conservation Planning Outline" clearly lists ceramic metal halide lamps as the preferred light source for the promotion of new energy-saving technologies. Prof. Zhu Dingchang, professor of the Institute of Electric Light Sources of Fudan University and the chief technical expert of Zhejiang Xinguangyang Lighting Co., Ltd., said in an interview with the China Economic Herald reporter that the advantages of high-pressure sodium lamps and quartz metal halide lamps in ceramic metal halide lamps are In one body, the advantages of using ceramic metal halide lamps for urban road lighting are stable light color, comfortable and transparent, energy saving and long life. At night, a 150W ceramic metal halide lamp has at least the equivalent of a 600W high pressure sodium lamp.
Ceramic metal halide lamps are cutting-edge technology products. The core technology and market of ceramic metal halide lamps have long been monopolized by international lighting giants such as Osram, Philips and General Electric. After the domestic enterprises developed the ceramic metal halide lamp, Philips' ceramic metal halide lamp immediately cut the price by 30~40. Xinguangyang general manager Yan Jianyue told the China Economic Herald reporter that at present, China's ceramic metal halide lamp manufacturing technology has reached the international level. Domestic ceramic metal halide lamps are not only used in urban lights such as Haining, Lhasa, Yichang and Tianjin, but also exported to Korea, the United States and other countries.
The relevant person in charge of Haining City Street Light Management Company introduced the road lighting renovation of Haining Avenue. Haining Avenue, Haining City, Zhejiang Province, carried out road lighting renovation in April this year, using ceramic metal halide lamps instead of high-pressure sodium lamps. After the renovation, Haining Avenue's light is transparent and comfortable, the lighting quality is in line with national road lighting standards; the power saving effect is obvious, saving 3.13 million kWh per year, saving 1033 tons of standard coal, reducing carbon dioxide emissions by 3121 tons, and reducing nitrogen dioxide emissions by 94 tons. .
Experts from the Road Lighting Association spoke at the meeting about several prominent issues encountered in LED promotion. First, subsidies for excessive LED lights have weakened economics. The promotion of foreign LEDs is very different from that in China. Because foreign subsidies for energy-saving lamps are not many, they consider economical considerations in terms of energy-saving lamps. Among them, input cost and traffic volume are important reference indicators. The domestic subsidy for LED lights is not conducive to the selection and promotion of other high-efficiency energy-saving lighting products. Second, the maintenance is inconvenient. The street lamp maintenance is mostly at high altitude in the middle of the night. Because the LED street lamp is damaged in some parts, the whole lamp needs to be replaced. It is very inconvenient for the maintenance worker to carry more than 10 kilograms of the lamp head, and the maintenance of the ceramic metal halide lamp only needs to bring a light bulb, which is more convenient. Third, the LED street light product interface is not uniform and the interchangeability is poor.
