Abstract
This paper presents a universal power supply for high-luminance LED lamp test. The proposed power supply is designed and implemented by adopting an improved single-stage Flyback configuration. A constant current control method is used to regulate the lamp current and brightness under different pieces of LED series connection. A laboratory prototype has been built and tested. With the prototype, high efficiency, high power factor, and constant lamp current can be achieved for the performance test of various LED lamps.Keywords
