中文摘要 | 高照度氣體放電燈已被廣泛地應用於戶外及工業照明,其中複金屬燈以 其高演色性,高發光效率及壽命長等優點,因此在商場、家庭等場合有逐漸取代 其他光源的趨勢。傳統式複金屬燈安定器因重量重、體積大、效率低等缺點使應 用範圍受到很大的限制。藉由電力電子的技術能力,使研發之電子式安定器得以 輕薄短小化,克服傳統式電磁安定器之缺點。本文將介紹複金屬燈之靜態與動態 特性,討論其電子式安定器之設計方法及當與燈源匹配時應該考慮的輸出特性需 求。 |
英文摘要 | With oustanding features of good color rendering, high lighting efficiency, stableluminance, and long life time, metal halide lamps gradually become one of the mostpopular lighting sources in our modern life. Conventionally, a high reactance inductoris used to ballast the lamp. Due to its low efficiency, huge weight and size, this electromagnetic type ballast is not proper to use in some area of application, such as office,hospital, factory applications, etc. This paper presents circuit designs of metal halidelamp electronic ballasts operating at high frequency (20-25kHz) which excludes theacoustic resonance frequency ranges. Special requirements ware discussed withrespect to the matching considerations between the electronic ballast and the lampload. Finally, expermental comparison for metal halide lamps started by two types ofballast circuits namely, conventional and electronic ballast is illustrated. |
