30W급 조명용 LED전원의 구동장치에 관한 연구

Abstract

In recent years, the global energy shortage and environmental pollution problems are being increasingly prominent, people earnestly hope to apply a new technology to save energy and protect environment. LED illumination light-source is just this kind of charming new technology. People attach ore and more importance to the semiconductor illumination for its remarkable merits just as longevity, energy saving, green environmental protection and so on, and consider it as the most valuable, new light source in the 21st century. The relatively recent development of light emitting diodes is proving to have significant impact in lighting technology. In this paper study up on the theory, characteristic of LED and the parameter which is necessary consideration in drive circuit design and the sting configuration method. To operate on 30W LED Array, this paper proposed and compared the mode of a constant voltage driver, constant current driver and constant voltage¤t driver.
