高效能智慧型LED室內照明系統之研製
為了解決LED Driver IC PWM 的問題,作者卓晁毅 這樣論述:
隨著環保意識與節能的興起,高功率LED因具發光效率高與壽命長等較傳統光源優異之特徵,在照明系統上已逐漸成為各類型光源的主流。本研究針對室內照明,設計及實現一高效能智慧型LED照明系統。該照明系統的主電路架構採用基於直流匯流排分佈式電源之多通道定電流轉換器做為LED驅動源,並以電流型降壓轉換器實現輸出電流的獨立控制。驅動源為返馳式轉換器,其具有功率因數校正與電氣隔離之特性。控制方面,驅動源以數位訊號處理器(DSP)作為核心,透過閉迴路PI控制,達到固定電流輸出調變;此外,在LED調光方面以微控制器(MCU)實現模糊(Fuzzy)控制調整照度和色溫,達到所設定之目標情境需求。另一方面,為了達到遠
端無線調控,本研究利用MIT App Inventor2設計手機APP程式,使其具有四種情境設定功能。最後,實現一16.8W的照明系統原型,並進行驅動源特性與情境調光測試,測試結果顯示,系統效率最高可達87.3%,且使照明指標穩定於目標情境,而不受外部光源的干擾。
