In the past few days, the landscape lighting on the railings of the Suzhou Gucheng River and its bridges across the river was as splendid as usual. The original 25-watt chilled cup light has been replaced with a 3-watt LED (also known as a light-emitting diode) in the past few days. The effect is the same, but the power consumption is greatly reduced. Save 40,000 kWh. Ye Feng, chief engineer of Suzhou City Lighting Management Office, was pleased to inform this reporter: Last year, Suzhou city lighting used 34 million kWh of electricity, saving 7.3% over the previous year; in the first quarter of this year, it saved about 6% of electricity. Save 2 million kWh.
Suzhou attaches great importance to the use of energy-saving products in new construction projects, and actively adopts low-energy, high-efficiency, high-light-emitting light sources, high-efficiency, high-maintenance lamps, and energy-saving appliances. At the same time, it also pays great attention to the energy-saving technical transformation of the original facilities. For example, in 9 lighting projects such as Xihuan Elevated and Youxin Interchange, 1422 sets of variable-power ballasts are installed. This alone can save 320,000 electricity for the whole year. After all, this year will continue to transform 1200 lamps. Since last year, all new street lights of more than 250 watts in downtown Suzhou have such intelligent functions. In addition, Suzhou City has saved a lot of energy through scientific management. For example, some roads have few vehicles and pedestrians in the middle of the night, and the requirements for lighting are not high. Suzhou uses the upper and lower nights on these roads, that is, only 50% of the street lights are turned on in the middle of the night. Some landscape lights are usually illuminated at 9pm or a later time depending on the season and the specific situation.
