LED Street Lamp Power Supply Design Requirements
Aug 03, 2017


LED street light power system is also different from the traditional light source, LED special constant current drive power is to ensure its normal work of a cornerstone, a simple switching power supply program often bring LED device damage. How to make a tightly packed together a group of LED security, but also an indicator of LED lights. LED on the drive circuit requirements is to ensure that the characteristics of constant current output, because the LED forward work when the junction voltage relative to the region is very small, so to ensure that the LED drive current is also a constant guarantee of LED output power is constant. For China's power supply voltage supply instability of the status quo, road lighting LED drive circuit with constant current output characteristics is necessary to ensure that the light output is constant and to prevent the LED super power operation.
