【摘要】 目前不管国内还是国外LED的驱动电路一般都采用直流电源来供电,本文将介绍用交流电直接驱动LED的技术,因LED具有响应时间短,高频性即理论上可闪烁无数次等特点。故此我们可直接用交流电来点亮LED,并且经过分析交流电直接驱动LED有诸多的优点。更多还原

【Abstract】 In most applications, LEDs are driven by a DC power supply, we will introduce the technology that allows LEDs to be driven directly from an AC supply in this paper. Because LEDs are illumined immediately,when the current is passing through them. Although LEDs freqently flash, they are not easily bad. After studying it, we find that AC offers several significant advantages.更多还原
