More and more cities with LED street lights will switch to use
With the rapid growth of LED street lamps and the background of energy saving and emission reduction, more and more cities have changed their street lamps to LED street lamps. LED street lights have a longer service life than old lights, but only consume half of the energy, which can save millions of dollars. Experts say that upgrading can increase a sense of security and can inspire locals and tourists to walk more streets at night. LED lamps have 'excellent visibility and color accuracyCompared with standard high-pressure sodium lamps, LED street lamps consume only 40% to 80% of electricity. The electricity bill for LED street lights can cost approximately RMB 2.35 million per month for a city. By using LED lights, the electricity bill to be paid can be reduced by 30% to 40%. The power system of LED street lights is also different from traditional light sources. The constant current drive power required by LEDs is a cornerstone to ensure its normal operation. Simple switching power supply solutions often bring damage to LED devices. The requirement of LED on the drive circuit is to ensure the characteristics of constant current output. Because the junction voltage is relatively small when the LED is working in the forward direction, ensuring the constant LED drive current basically ensures the constant output power of the LED.
