The reporter learned from the information industry department that at present, Weifang City, Shandong Province has installed high-power LED street lamps close to 11,000 盏, and the different types of LED street lamps used in the daily power saving exceeds 24,000 kWh, and the annual power saving exceeds 8.9 million kWh. The discharge of sulfur dioxide, carbon dioxide and dust has significant social and economic benefits.
It is understood that the Weifang semiconductor lighting industry has formed a relatively complete industrial chain from the production of epitaxial wafers, chip fabrication to device packaging, to semiconductor lighting and other application products. During the 11th Five-Year Plan period, the municipal government set up a high-tech industrial development fund of 200 million yuan per year, focusing on supporting the development of the optoelectronics industry, supporting the purchase of key equipment, and promoting product research and development and industrialization. At present, Weifang relies on Shandong Ruisen Huaguang Optoelectronics, Zhongweiguang Electronics, Huaguang Xinneng and other enterprises to form a high-power light-emitting device chip package and production place for application products such as street lamps, landscape lighting and general lighting; LD die occupied More than 70% of the domestic market, production and sales rank first in the country; white LED lighting products from low power to more than 100 watts, high-power LED single-tube luminous efficiency of more than 100 lumens / watt, reaching the domestic leading level.
In order to accelerate the promotion and application of semiconductor lighting products, the city has also implemented a high-power LED lighting demonstration project, using the newly developed high-efficiency energy-saving and environmentally-friendly LED street lamps to promote the application of urban green lighting systems on a large scale. At present, high-power LED street lamps have been installed close to 11,000 盏, among which the street lighting in Weifang High-tech Zone has all been replaced with LED street lights. All new or replaced street lamps in Weifang urban area are all equipped with LED street lights. LED street lights installation in various counties and cities are also underway. in. LED street lights show very significant energy-saving effects while maintaining the same (or better) road illumination and meeting the road lighting standards of the Ministry of Construction. The measured energy is 69% compared with high-pressure sodium lamps, saving 70 compared with metal halide lamps. %the above.
