What is LED module power supply

View:42407/11/2019  

LED  module power supply is a power converter that converts the power supply into a specific voltage and current to drive the LED. Generally, the input of the LED module power supplyincludes high-voltage power frequency AC, low-voltage DC, high-voltage DC, and low-voltage high-frequency AC. The output of the LED module power supply is mostly a constant current source that changes the voltage as the LED's forward voltage drop changes.

A series of constant voltage constant current control electronic circuits are developed for the characteristics of led module power. The integrated circuit technology is used to control the input current of each LED to the optimal current value, so that the LED can obtain a stable current and generate the highest output luminous flux. The LED module power supply preferably controls the magnitude of the LED current when factors such as input voltage and ambient temperature fluctuate.
