  本論文利用發光二極體晶粒當成熱源,設計出一發出遠紅外線的熱放射二極體,研究其工作電性與遠紅外線溫度特性,最後將熱放射二極體應用在熱像的七段顯示器,以及開發製作遠紅外線真空拔罐器。本論文的架構是第一章介紹動機與基礎概念,第二章介紹介紹接面溫度理論與與相關應用到的量測設備,第三章介紹整體封裝流程與相關應用電路設計,第四章則是完整的實驗結果與討論,第五章則是結論。
  研究中為了能當顯示器應用,熱放射二極體的熱放射溫度必須維持工作在某一個高溫準位和低溫準位,因此採用脈波寬度調變(PWM)、致冷晶片(TEC)作優化設計。在可靠度研究方面,接面溫度是一項關鍵因素,當控制熱放射二極體的接面溫度在低於110 oC時,其順向工作電壓的限制是設計電路的重要參考指標,亦可掌握對應之遠紅外線輻射溫度的極限,研究發現當提供的電流在0.08A~0.2A時,TED的Vf(min)最低大約在1.8V左右,且當工作電流大於0.2A以上時熱放射二極體容易造成燒毀。
  最後將熱放射二極體應用於七段數字顯示器上,使可見光與遠紅外線可以同時顯示,人眼看計數器時會看見0數到9,用遠紅外線熱像儀觀察可以看見9數到0。另外在遠紅外線真空拔罐器應用上,熱放射二極體的溫度可達40~50oC,該具遠紅外線的拔罐療程,期能促進改善血液循環效果。
In this paper, the LED grains are used as heat sources to design a thermal emission diode emitting far infrared rays. The operation electricity and far infrared temperature characteristics were studied. In the final, the thermal emission diode was applied to a seven-digital display with visible and thermal view, and also used to develop a far-infrared vacuum cupping device. The structure of this paper is shown that the first chapter introduces the concept of motivation and basic, the second chapter introduces the theory of surface temperature and related to the application of measurement equipment, the third chapter introduces the overall packaging process and related application circuit design, the fourth chapter is a complete experimental results and discussions, and the fifth chapter is the conclusion.
In order to use as a display, the temperature of a thermal emission diode must be maintained at a high and a low temperature level. So the pulse width modulation (PWM) method and the thermoelectric cooler (TEC) are used to optimize the design. In the reliability study, the junction temperature is a key factor. When the temperature of the thermal emission diode is lower than that of the 0.08A~0.2A, the limit of the operating voltage is an important figure-of-merit to design the circuit, and the limit of the corresponding far infrared radiation temperature is found. The Vf (min) of the TED is about 1.8V which is the minimum boundary requiring to have a safe operation. In addition, when the operating current is greater than 0.2A, the thermal emission diodes are prone to burn.
Finally, the thermal emission diodes were used in the seven-digital display, so that the visible light and the far infrared radiation can be displayed at the same time. The counter number could be varied from zero to nine as people seen, and the counter number could be varied from nine to zero with the far Infrared Thermal Imager Recorder. In addition, in the far infrared vacuum cupping application, the temperature of the thermal emission diode can be heated up to 40~50oC. The blood circulation with the far infrared assistance was expected to improve the effect during the cupping treatment.
