本發明旨在揭露一種LED發光元件之主動功因修正驅動系統,其係包含一啟動電路、一量化電路以及一脈波控制處理電路,啟動電路與量化電路電性連接,量化電路與脈波控制處理電路電性連接。啟動電路接收一整流電壓以啟動該驅動系統,量化電路將整流電壓進行電壓量化以產生複數個數位訊號,脈波控制處理電路依據該些數位訊號進行編碼、閂鎖、解碼、計數以及比較等步驟而產生至少一切換訊號。爾後,切換訊號控制至少一切換開關,而調整發光元件之一驅動電流,換言之,透過切換訊號之責任週期的變化,而調節切換開關驅動發光元件之電流供應方式 The present invention is directed to an active power correction drive system of an LED light emitting element comprising a start circuit, a quantization circuit and a pulse wave control processing circuit, the starting circuit electrically connected with the quantization circuit, the quantization circuit and the pulse wave control The circuit is electrically connected. The start circuit receives a rectified voltage to actuate the drive system, which quantizes the rectified voltage to produce a plurality of digital signals, and the pulse wave control processing circuit encodes, latches, decodes, counts, and compares the digital signals according to the digital signals And generating at least one switching signal. Then, the switching signal controls at least one changeover switch, and the driving current of one of the light emitting elements is adjusted.
