摘要：
A high efficiency driver is proposed for the high-brightness white LED lamp. The driver consists of a dc power source in series with a current regulator. The current regulation is accomplished by partially processing the power from the dc power source. The dimming feature of the LED lamp can be made by regulating the current. The detailed circuit operation stages and analysis are provided. A laboratory circuit is designed for an LED lamp which is composed of eight high-brightness LEDs. Experimental results demonstrate that a high efficiency can be achieved even at a dimmed lamp power.
