在LED問世後，相關的技術不斷的發展也漸趨成熟。驅動器架構可略分為隔離式和非隔離式兩種；為因應LED驅動器在安規上面的需求，隔離式架構逐漸成為LED驅動器的主流之一。在市場的需求下，驅動器朝著縮小體積的方向不斷演進，設計者需要克服有限的電路板面積來滿足電路保護、系統可靠性、及符合世界各地能源法規要求。同時最重要的是在節能意識高漲下，智慧節能的需求日益增加。 先前的研究 '基於無線通訊技術之雲端自動化高可靠度節能LED照明系統及其系統分析' 提出一種基於無線通訊技術的節能LED照明系統。而本研究提出一種透過LED返馳式驅動器所產生的磁場效應，來傳遞數位資訊、並藉由這些資訊來自動調整LED的亮度。 此外，先前研究需使用路由器來進行雲端照明管理；而本研究則可省去無線傳輸的架設環境，以磁場通訊方式來完成照明系統之管理。主要是藉由系統二次側的微控制器使用頻率位移鍵送技術，將數位資訊回送到一次側；而系統的一次側則透過微控制器偵測頻率的變化來解讀其控制訊號，並對LED驅動器做對應的亮度調整，來達到智慧照明之管理。 ; After the innovation of LED was release, the relevant technology of LED has became more and more mature. There are two types of driver, isolated and non-isolated. In terms of the safety requirement of LED driver, isolateddriver has became the most popular driver in the market. Due to the requirement of minimizing the size of driver in the market, inventors of driver have to overcome the limitation of areaby the PCB, circuit protection and the requirement of the system liability. Since the awareness of energy saving and the energy regulation in the world, the inventors of the driver have to follow the energy relation in order to design a qualified driver. According to the research ' LED Lighting Cloud Service Analysis and Implementation Based-on Wireless Communication for Energy-Saving and High Reliability ' It states that the energy-saving LED lighting system are based on wireless communication technology. This research provide an improvement LED fly-back driver Transformer magnetic field generated to pass information and respond to these information automatically adjust the LED brightness. This study offers a method without setting up wireless transmission. For instance, the previous study proposes the router without the cloud lighting management system can automatically adjust the LED brightness to achieve energy-saving effect. magnetic field communication is done by the secondary side of the microcontroller Frequency-Shift Keying to send data back to the primary side. while the primary side of the microcontroller through the detection of changes in frequency ... |
