T5螢光燈管因具有體積細小、原材料耗損少、光效高、演色性好、光衰小、省電等優點，為21世紀綠色照明理念較佳採用的光源產品。螢光燈管在使用上必須搭配一電子安定器，而傳統T5螢光燈電子安定器無法控制燈絲預熱溫度，造成T5螢光燈管啟動時常有冷啟動與預熱過度等問題發生，嚴重地縮短T5螢光燈管之壽命，減損了T5螢光燈管原有的優點。故本文研製一新型之T5螢光燈電子安定器，具有控制T5螢光燈管燈絲預熱之溫度，避免冷啟動與預熱過度之情形發生，可有效地延長T5螢光燈管之使用壽命。最後本文針對T5 28W螢光燈管設計一T5螢光燈電子安定器以驗證其性能，並與傳統電子安定器比較。實驗結果顯示，本文所提之T5螢光燈電子安定器具有控制燈絲溫度於700˚C~750˚C範圍內，可有效地避免螢光燈管有冷啟動或過熱濺射之情形發生。

T5 fluorescent lamp is one of the best green products of 21 century due to some advantages having tiny volume, few raw materials, high energy photon, best color rendering, less light declining and energy saving. Traditional electronic ballast can’t control pre-heating temperature of filaments, that will result in cold-start and over pre-heating for T5 fluorescent lamp. It will not only shorten the life, but also devalue the inherent advantages of T5 fluorescent lamp. To avoid the above-mentioned problems, a novel electronic ballast for T5 fluorescent lamp is proposed in this thesis. The proposed electronic ballast can not only control pre-heating temperature of filament, but also avoid starting without warming and over pre-heating for T5 fluorescent lamp. Finally, a prototype for T5 28W fluorescent lamp is designed and implemented to verify the performances. In comparison with traditional electronic ballast, the proposed electronic ballast can control temperature of filament from 700˚C to 750˚C with the aforementioned features and extend the life of T5 fluorescent lamp.
