Zhang Yang, general manager of State Grid Zhejiang Electric Power Research Institute Energy Saving Service Co., Ltd. said that the high-pressure sodium lamp on the road was replaced by LED street light, and the lighting effect was not affected. The energy-saving effect was very obvious.
He used the figures to prove that Tongxiang currently used 4427 ç› LED street lights for street lighting renovation, saving more than 3 million kWh of electricity every year and saving more than 2.7 million yuan in electricity every year. There are a total of 17,884 street lamps for energy-saving renovation in Jiaxing, but the annual electricity consumption exceeds 10 million kWh.
According to reports, LED is a fourth-generation light source technology that is efficient, energy-saving and environmentally friendly. Under the premise of ensuring the same illumination level, energy saving rate of 50 or more can be achieved. The energy saving effect of ordinary spotlights even reaches 90.
According to the reporter's understanding, the Tongguang urban expressway and main road street light source mainly used 250W high-pressure sodium lamp. Although the brightness is high, the power consumption is large, and it will be replaced in 2 years. The maintenance and replacement cost is high; but the LED street lamp is used instead. When the brightness is constant, the power saving rate is above 50, and the service life of the LED street lamp is 6-7 years according to the existing design. The supplier has a 3-5 year warranty period, and the repair rate is very low.
It is estimated that although the difference in operating costs is not obvious, the workload is reduced in maintenance, and the advantage in saving electricity costs is obvious.
According to the plan, Zhejiang Province will widely promote the use of LED lighting products in the field of lighting engineering, such as roads, public places, government agencies, state-owned enterprises and institutions, or other state-owned capital investment, and accelerate the promotion of non-public lighting. The control target of total energy consumption and electricity consumption during the five periods.
