Investigate the high-efficiency use indicators of outdoor solar street lights
The power system of outdoor solar 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 supplies often cause damage to LED devices. Therefore, how to make a group of tightly compressed LEDs safe is also an indicator to investigate the high-efficiency use of outdoor LED street lights. 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. For the current situation of constant power supply voltage supply in my country, it is very necessary for the driving circuit of the road LED street lamp to have a constant current output characteristic, which can ensure the constant light output and prevent the overpower operation of the LED brightness. If the outdoor LED street lamp wants to make the LED drive circuit exhibit constant current characteristics, looking inward from the output end of the drive circuit, its output internal impedance must be high. When working, the load current also passes through this output internal impedance, so the correct solution is to use active electronic switching circuits or high-frequency currents to ensure normal use.
