本篇論文探討電力線通訊應用在封裝上內含RGB三原色發光二極體上,以完成調光調色的變化。在電路上可分成2部份探討。第一部份為電力線通訊(Power Line Communication ,PLC);第二部份為發光二極體控制電路部份。
在電力線通訊使用的調變技術為On Off Keying (OOK),利用單晶片做出12bits可控制的數位訊號。當數位訊號和125KHz的脈波訊號,二者相乘以做出的OOK調變訊號。使用可承受高驅動電流的Line Driver,連接至變壓器上,將之耦合到電力線。再由接收端電路中的變壓器、Sallen-Key帶通濾波器,自動增益控制電路(Automatic Gain Control ,AGC)、解調變電路與比較器電路,最後將OOK調變訊號還原成數位訊號。
在控制LED的部份,將PLC所傳送的12bits訊號,切成3等份分別給RGB三原色LED使用。由於每種顏色有24種變化,所以完成的混光混色變化共有(24)3種顏色。混色的機制採用通道脈波調變(Pulse Width Modulation ,PWM ),寬度為6.7%。

This thesis is discussed power line communication applications in the LED package which is contain RGB tricolor to complete the changeing of color dimming.The circuits are divided into two architecture power line communication and the second is LED control circuit.
This thesis is using On Off Keying(OOK)modulation and single chip to complete 12bits digital signal which can be controled in the power line communication. The digital signal and the 125KHz of pulse wave signal are multiplied to produce the OOK modulation signal. Line driver with high driver current tolerate are used to connect with the transformer and then couple to the power line. OOK modulation signal is restored to digital signal through transformer, band pass filter, automatic gain control(AGC)circuit, demodulator circuit and comparator in receiver circuit.
In the LED part, 12bits PLC signals will be seperated into 3 equal portions were used to RGB LED, each color has 24 variations, so after mixing and blending colors will have (24)3 colors. Because the type of mixcolor is use to pulse width modulation(PWM) so the PWM width is 6.7 %.
