Technical details and manufacturing context for Driver

Definition
A driver is an essential electronic component within LED downlight systems that converts incoming AC power to the appropriate DC voltage and current required by the LED chips, ensuring stable operation, preventing flicker, and protecting against voltage fluctuations.
Working Principle
The driver receives alternating current (AC) from the mains power supply, rectifies it to direct current (DC), then regulates and stabilizes the output through switching or linear regulation circuits to match the specific electrical requirements of the connected LED modules.
