Abstract:	人類生活水準不斷的提升，各類型家電及電力設備不斷增加電力需求，因此對於能源的消耗也一直不斷的提升，我國每年照明用電約260億度電，占全國總用電 2298 億度的 11.3％。近幾年因為溫室效應，天氣劇烈的變化造成人類前所未有的浩劫，人們也開始注意到過度使用能源所造成的嚴重後果。　　本篇論文中，我們提出了利用發光二極體的特性使其二極體整流的同時也動作發光。將使物盡其用並加入功率因素校正電路的方式，達到無交流轉直流驅動器所產生的損失並達成提高功率因素進而達到提高效率。 The High efficiency AC LED circuit study (LED; Light Emitting Diode) lighting components in common at the moment, compared to traditional incandescent bulbs with high luminous efficiency, low power consumption and low pollution characteristics, so that all kinds of LED AC light emitting circuits also began to appear on the market, however, because the light emitting diode itself can only be a single Wizard works, makes it difficult to use in an AC environment. The papers Research Department an high efficient AC LED circuit has a rectifier glow unit and the a passive load steady stream component; the rectifier glow unit has four group rectifier glow Department, the Group rectifier glow Department contains has plural series received of LED component, and connection for a full bridge circuit; which the passive load steady stream component Department series received Yu the rectifier glow unit of output end to stable guide pass loop current and not over the LED component by rated of safe rating, Ensure the rectifiers have the desired luminous efficiency light emitting unit and to prevent excessive current burning of the LED components This research LED AC light circuit only requires the rectification made light unit can achieve effectiveness and increase the power factor of rectification and luminescent, able to reduce the use of components in order to reduce the circuit size.
