技術說明

目前一般市售之三級式與兩級式電子照明驅動電路皆有效率不高、元件成本較高等問題。另外，於高強度氣體放電燈之電子照明驅動電路之設計時須考量到音頻共振現象造成放電弧光不穩定之問題。因此，本發明係一種新型單級高功因低頻方波驅動之高強度氣體放電燈電子照明驅動的裝置，用以取代一般市售具有三級式與兩級式電路架構的高強度氣體放電燈電子照明驅動電路，並具有高功因、高效率、低電路成本等特點，且供給燈管一穩定之低頻方波電源，可避免音頻共振現象的發生，以確保燈管放電弧光穩定且不閃爍。 The disadvantages of the conventional three-stage and two-stage drivers for electronic lighting applications are limited efficiency and large numbers of circuit components. The acoustic resonance phenomenon which results in an unstable discharging arc is required to be concerned while designing the electronic lighting driver for high-intensity-discharging lamps. Therefore, a novel single-stage low-frequency square-wave driver instead of traditional ones for high-intensity-discharging lamps with high power factor is proposed in this invented patent. The features of the presented single-stage driver are high power factor, high efficiency and small numbers of circuit components. Due to supply low-frequency square-wave sources with the lamp, no acoustic resonance occurs and a stable discharging arc is obtained in the lamp.
