General Study on the Dimming Control of the LED Lighting Device

摘要

Dimming control is used for energy saving scheme in most of the general lighting system. There are different kinds of dimming control methods in the lighting device. This paper aims to provide a general discussion on the power circuit to lighting up the LED devices and it also discusses the possible way to dim the LEDs. Moreover, this paper based on the 3W high power LED and aims to find out the best operating factors that can fully utilize LED and to provide best energy saving scheme.
