碩士 === 國立臺灣科技大學 === 電機工程系 === 101 === The study of developing LED road lighting that devising the three-phase power source to provide electricity from distribution system to AC LED for road lighting luminaire directly without step-down voltage transformers and simplify the controlled circuit configuration. Additionally, the LED is used for its energy-saving property and meeting the requirement of national energy-saving and carbon reduction policy. The study completed a practical dimmable circuit for LED road lighting by using SCR to set up the rectifying circuit. The reliability and marketing competitiveness of LED have been improved to verify the practiveness. Meanwhile, the experiments show that the flikering and total harmonic distortion(THD) of AC LED driven by three-phase power have been reduced than driven by single-phase power source. The result could be a guidence for the road lighting.
