With the advent of LEDs, the way we use lights have totally changed. Today we want to control our lights as per our environment and as per our mood. LED drivers allow us to do this. They improve the overall efficiency of light allowing them to give more output with a very small input, as compared to the other types of lights. Here are few articles that will help you understand the use of LED Drivers.
Efficiency and duarbility of any LED light is not just related to the LEDs used but also depend upon the type of LED drivers that operate them.
Universal drivers cannot be used as an LED driver.
LED drivers regulate the output current rather than output voltage and help the LEDs to operate in a safe operating range.
Dimming and color changing are the features enabled by LED drivers.
