高亮度發光二極體(LED)擁有較高的轉換效率及使用壽命，因此逐漸取代了傳統光源。而且LED具有操作電壓較低的特性，因此在應用上更適用於較低電壓之直流電源。另一方面，由於智慧手機與個人平板電腦的熱潮，觸控面板在消費性電子的使用上越來越普及。此外，無線通訊技術可以方便的連結，提供了在產品的雙向溝通、供應商的獨立性及廣闊的市場等優勢。
　　本文將ZigBee無線網路建立在一套LED照明控制系統中。所提出的系統包含了三個RGB LED燈條、一個白光LED燈條、觸控面板、ZigBee無線技術做為遠端數據的傳送及利用返馳式轉換器做為輔助電源。ZigBee是一種低成本、低功耗的無線技術，特別適用於感測網路的中數據傳輸速率。本文利用觸控面板作為輸入介面，透過ZigBee無線網路傳送數據，使用者可以任意控制LED色彩及亮度的變化。硬體與韌體的設計會在文中詳細介紹。最後的實驗結果亦證實ZigBee技術適合應用於家庭自動化及情境照明的使用。

　　High intensity light emitting diodes (LEDs) are attractive candidates for replacing conventional light sources such as incandescent lamps and fluorescent lamps. LEDs have substantially higher light conversion efficiencies than incandescent lamps and longer lifetimes than both types of conventional light sources. Finally, LEDs require lower voltages than fluorescent lamps, and hence, are better suited for applications in which the light source must be powered from a low-voltage DC source. On the other hand, touch panel technologies are increasing utilized in consumer electronics due to the popularity of smart phones and flat panel personal computers. Moreover, wireless communication protocols enables easy connection, therefore offers advantages include product interoperability, vendor independence, and accessibility to broader markets.
　　In this thesis, a LED lighting control system based on the ZigBee wireless network is proposed. The presented system includes three RGB LED light bars and one white LED light bar, a capacitive touch panel, ZigBee communication modules for remote control and a flyback auxiliary power supply. ZigBee is a low cost, low power wireless technology specially intended for medium data rate sensor networks. Using the touch panel as the input interface, user can arbitrary dim the brightness and change the color of the LED light bars. The hardware and software design will be presented in detail. The experimental and application results have shown that ZigBee technology is suitable for wireless control in home lighting and proved that the presented wireless sensor network has a more vast range of prospects in home automation and scenario lighting.
