本論文藉由觀察螢光燈壽命即將終了前的故障現象，並依此特性設計螢光燈故障偵測保護電路。螢光燈在壽命終了前仍舊可以被點亮，但卻無法維持正常工作，其外觀會產生單端燈絲發紅和弧光閃爍等現象，而且很明顯的發光效率比正常工作時來得低，弧光閃爍嚴重時甚至會使燈絲燒毀進而熄滅。
此外，在研究中發現當故障現象發生時，燈管電壓和燈管電流波形都會有正負峰值不對稱的情形，其中燈管電壓的不對稱情形比起燈管電流明顯許多，除此之外，燈管電壓還會含有直流成分。根據以上觀察所得，設計適用於可調光之螢光燈電子安定器故障偵測保護電路，經由實驗驗證電路確實能夠達到故障偵測及保護的作用。

The fault phenomena of fluorescent lamps are investigated by observing the operations in the last period of the life cycle. Accordingly, fault detecting and protection circuits are designed.
Before coming to the life-end, the lamps can be started up, but are operated abnormally. A ruddy glow may occur at one end of the cathode filaments and an unstable arc may happen to the lamp. Obviously, the light efficiency becomes relatively low. The arc instability eventually results in a totally damaged fluorescent lamp. It is found that both waveforms of the lamp voltage and the lamp current are asymmetrical and have unequal positive and negative peak values. The asymmetry is more significant for the lamp voltage. In addition, a dc component is present in the lamp voltage. Based on these investigated results, the detection and protection circuits are designed for high-frequency electronic ballasts under dimming operations as well at the rated power. The experiments show that the detection and protection circuits can work effectively.
