發光二極體(Light-Emitting Diode, LED)是能發光的半導體電子元件，具有效率高、壽命長、反應速度快、可靠度高等傳統電源不及的優點，因此逐漸取代傳統光源。並且LED具有操作電壓較低的特性，所以更適合應用於較低電壓之直流電源。另一方面，由於智慧型手機與平板電腦的崛起，改變了人類的生活習慣。許多商品透過無線傳輸，提供了不同以往的操作模式，也使得個人生活變得更加便利。藍芽幾乎是每部智慧型手機與平板電腦標準配備的功能，因此本文將利用藍芽網路來建立起Android系統手機與LED照明控制系統中溝通的橋樑。所提出的系統包含了RGB LED燈條、Android手機，以及藍芽作為遠端數據傳送及利用返馳式轉換器做為輔助電源。藍芽是一種低成本、低功耗的無線技術，可應用在電腦、行動電話、及其他家電用品上，透過藍芽傳送數據，使用者可以任意控制LED色彩及亮度。硬體與韌體的設計也會在文中詳細介紹。

High intensity light emitting diodes (LEDs) are available in an ever-increasing number of general lighting products. In addition to advantages such as higher energy efficiency and longer life, LED lighting also boasts advantages including low profile, compact size, cold temperature operation, fast turn on time and full controllability. For LED lighting applications, lighting control includes dimming and color control offer potential for increased energy efficiency and user satisfaction. On the other hand, tablets are gaining their popularity due to their portability and their ease of use. The tablet users can use a touchscreen to react to what is displayed and to control how it is displayed; therefore is a suitable candidate for home automation. Of all the user interfaces for home automation, touch screens are the most intuitive and easiest to use. In this thesis, a LED lighting control system based on the Bluetooth wireless network is proposed. The presented system includes three RGB LED light bars and one white LED light bar, a lighting control app for tablets and a Bluetooth communication module for remote control. The hardware and software design will be presented in detail. The experimental results show that tablet is a good candidate for home lighting control applications. Moreover, tablet apps enable easy connection; therefore offers advantages include product interoperability, vendor independence, and accessibility to broader markets.
