Recently, Yinchuan City cooperated with China Energy Conservation and Environmental Protection Group Jinghe Lighting Co., Ltd. to replace the city’s 45,000 high-pressure sodium lamp source with LED energy-saving lamps. This work is expected to be completed before the Spring Festival in 2019.
In addition, Yinchuan City will upgrade the road lighting control system. Each lamp can be uniformly dimmed according to actual needs at night. In the middle of the road illumination, the brightness of the light can be reduced in the second half of the night to achieve the effect of secondary energy saving.
According to the actual test and theoretical calculation, the annual energy saving after the project transformation is 36.3 million degrees, the power saving rate is over 60%, and the green lighting rate in Yinchuan is over 90%.
