Traditional street lights require a large power supply system. Large power transformers are very expensive. Moreover, traditional lamp voltage cannot fluctuate too much, otherwise it will seriously affect the lifespan of the lamp. And LED street lights use the driver module of Sunshine Shengyuan Technology, without the need for large transformers. When the voltage fluctuates, the brightness of LED street lights remains unchanged. T220C350W12S12 can drive a 12W LED, and the entire driver can achieve constant current driving when the voltage changes from 180V to 260V. Ensure the brightness of high-power LED street lights. In addition, the driver has many protection functions, which ensure the reliability of the entire power grid in abnormal situations.

Comparison of energy-saving between LED street lights and traditional street lights

Let's calculate the annual electricity consumption cost for a three section road with two light sources. The calculation method is based on turning on the light for 10 hours per day and calculating at 1 yuan per kilowatt hour. The annual power consumption of traditional streetlights on 3-kilometer roads is 184325 kilowatt hours, equivalent to RMB 184325. The total annual power consumption of LED streetlights is 36865 kilowatt hours, equivalent to RMB 36865. The total annual power consumption of traditional streetlights on 5-kilometer roads is 303863 kilowatt hours, equivalent to RMB 303863. The total annual power consumption of LED streetlights on 10-kilometer roads is 607725 kilowatt hours, equivalent to RMB 607725. The total annual power consumption of LED streetlights is 121545 kilowatt hours, RMB 121545.
