CIRCUITS FOR CONTROLLING OF A LIGHT EMITTING DIODE

摘要

PURPOSE: A control circuit of an LED module reduces heat generation by using a relatively small number of LEDs. CONSTITUTION: An AC power source supplies a power voltage. A rectifier (200) rectifies the power voltage into DC. An inverter (300) converts the output voltage of the rectifier into AC. An AC-direct driver (400) receives the output voltage of the inverter. The AC-direct driver supplies the output voltage of the inverter to an LED.
