LED lights use more and more cities will be replaced

With the high-speed development of the LED street lamp and the context of energy conservation and emissions reduction, more and more cities will be the street lamp to replace into the LED street lamp. LED street lamp longer service life than old lamps, but only half of the energy consumption, can save millions of dollars. Experts say, upgrade can increase a sense of security, can stimulate the locals and visitors to walk more streets at night. LED lamps and lanterns has & other; Excellent visibility and color accuracy & throughout; And therefore can provide safer conditions for drivers and pedestrians. Compared with the standard of high pressure sodium lamp, LED lighting lamp consumes only 40% to 80% of the battery. LED street light, electricity, can a city will pay about RMB 2. 35 million per month. Through the use of LED lights, that is to pay the electricity bills can reduce 30% to 40%. LED street lamp power supply system is also different from the traditional light source, LED by realizing the constant current drive power, is to guarantee the normal work of a large foundation, a simple scheme of switch power supply damage often a LED device. LED to the requirement of the drive circuit is can ensure constant current output characteristics, because the LED forward junction voltage relative changes at work area is very small, so to ensure the LED drive current constant is basic guarantee for the LED constant power output.
