Yizhang Hunan's First LED Public Lighting Demonstration County

According to the Hunan Yizhang County Urban Management Bureau, the energy-efficient lighting for semiconductors in Yizhang County has been used as the first county to achieve green lighting in Hunan.

As the first demonstration county for public lighting energy-saving and emission-reduction, Yizhang introduced strategic investors China Chengguang Group this year and adopted the energy contract management model. The Chengguang Group invested 100 million yuan to build 15,000 public lightings in the county. In the past, a landscape lantern was 1400 watts. After transformation with semiconductor lighting, it was reduced to 337 watts, the brightness was increased by more than 10%, and the average street light was reduced from the previous 330 watts to 120 watts, and each of the energy-savings exceeded 70%. All semiconductor energy-saving street lamps all use long-distance automatic monitoring systems, through the radio transmission on the street lights, to achieve automated intelligent management. It realizes remote timing, automatic dimming, and achieves integration of energy saving and management.

After the public lighting of the county's nearly 40 kilometers is newly built and transformed, more than 4 million kilowatts of electricity can be saved annually. In 3 years, Yizhang will realize semiconductor-efficient and efficient lighting for all public lighting in the county, including 27 townships. Li Jiaguo, director of the Yichang County Urban Management Bureau, calculated for us an account. The electricity savings now can ensure that 20,000 households in the county can use electricity for a year.
