本論文旨在研製一直流高亮度發光二極體驅動控制電路，首先分析了高亮度發光二極體的發光特性，並進行不同方式的量測，此驅動電路將依直流發光二極體的溫度變化而選擇適當的驅動電流，使高亮度發光二極體持續操作於高發光效率。在本論文中首先利用電路驅動直流發光二極體，並操作於穩態下使用致冷晶片控制直流發光二極體的溫度，在定溫下，調整驅動電流記錄其光電特性；再來使用直流發光二極體加散熱片及無加散熱片，使發光二極體的溫度不受控制，調整其驅動電流記錄其光電特性，將所量測之數據整理成一資料庫，並分析溫度對直流發光二極體之光電特性的影響。本論文提出定電流驅動脈波寬度調變調光電路，以數位信號處理器MPC82E54AE為核心來實現系統之數位控制，
也特別加入超溫保護，以防高亮度發光二極體超溫而損壞，並實際研製電流驅動控制電路及不同場所亮度之調光控制，經由實驗結果顯示，在溫度40℃到60℃之間，其額定功率可維持在66%到80%。

This thesis focuses on the design and implementation high efficiency driving circuit for DC high brightness LED.At first, the electric and optical characteristics of high brightness LED are analyzed and measured with different methods. In order to operate the high brightness LED on high luminous efficiency continuously, this drive circuit is selected appropriate drive current by temperature change of DC LED. The circuit is utilized to drive DC LED, and the temperature of DC LED is controlled by used cooling chip on steady state. The electric and optical characteristics are recorded with adjusting the driving current on constant temperature. Different cases of DC LED with heat sink and no heat sink are considered, and the temperature of DC LED does not be controlled, the electric and optical characteristics are recorded by adjusting the driving current. The measured data is arranged as a database, and to analyze the temperature effect of DC LED. This thesis presents a constant current PWM dimming driver circuit, a digital signal processor MPC82E54AE as a core to implement digital control system. Further¬more, by adding over-temperature protection can prevent that the temperature of high brightness LED is too high to cause damage, and actually develop current drive control circuit and luminance dimming control for different places. The experimental results show that the rated power can be maintained 66% to 80% at the temperature between 40℃ to 60 ℃.
