With the rapid development of LED lighting, what are the development prospects of traditional high-efficiency energy-saving lighting products? Chen Yansheng, vice chairman and secretary general of China Lighting Association, believes that traditional high-efficiency lighting products will coexist with LED products for a long time to come. The market share of LED lighting products will gradually increase, but ceramic metal halide lamps will have considerable vitality. Ceramic metal halide lamps are still a hot spot in the research of international electric light sources.
The promotion conference of high-efficiency lighting and energy-saving technology for ceramic metal halide lamps sponsored by Beijing Energy Conservation and Environmental Protection Center was recently held in Haining City, Zhejiang Province. More than 160 people from the Urban Construction Department of the Ministry of Housing and Construction, the National Energy Conservation Center, and the China Lighting Association attended the meeting.
According to Zhang Hailu, honorary chairman of the Shanghai Lighting Society, ceramic metal halide lamps have the advantages of good color rendering, high comfort, high luminous efficiency, good economy and easy replacement compared with LED street lamps. The lamp has the advantages of high-pressure sodium lamp and quartz metal halide lamp, high luminous efficiency, good color rendering, long service life and good light color consistency, and has broad application prospects in the field of road lighting.
Zhu Dingchang, professor of the Institute of Electric Light Sources of Fudan University and chief technical expert of Zhejiang Xinguangyang Lighting Co., Ltd., believes that China's ceramic metal halide lamp manufacturing technology has reached the international level. He said that the advantages of using ceramic metal halide lamps for urban road lighting are high color rendering index, stable light color, comfortable and transparent, energy saving and long life.
According to Zhu Dingchang, at present, ceramic metal halide lamps have been adopted in urban lights such as Tianjin, Haining City, Zhejiang Province, Lhasa City of Tibet Autonomous Region, and Yichang City of Hubei Province. The quality of road lighting has improved and the energy saving efficiency is obvious.
