適合大型照明系統的環保中央節能器
隨著近年電子鎮流器被大量采用，而引發出一個值得嚴重關注的環保問題。電子鎮流器的平均壽命只有一至五年( 視乎素質及價錢而定), 廢棄的電子鎮流器含有大量不可分解的和有毒的物質，會造成嚴重的環境污染。而目前興起的新一代低損耗電感鎮流器，平均壽命超過二十年，其鐵芯也可在十數年后循環再用。本文首先通過對比實驗分析，證明低損耗電感鎮流器的效率已接近電子鎮流器。然后介紹一種可與電感鎮流器及電子鎮流器兼容的中央變壓調光節能專利技術。新技術保留電感鎮流器的環保、長壽、可靠和抗雷擊等優點，再加上節能功效，已在戶外及室內的大型照明系統上應用。
Abstract: With the active promotion by lighting industry of electronic ballasts, there has been rising concern with the increasing electronic waste problem. Electronic ballasts can last for typically 5 years. The used products contain toxic and non-biodegradable materials that can result in environmental pollution problem. New generation of low-loss magnetic ballasts, that are recyclable and can last for over 20 years, offer an attractive alternative. This paper shows that, based on a newly patented central dimming technology, dimmable magnetic ballast systems can be as energy-efficient as dimmable electronic ballast systems. The new central dimming technology is compatible with both electronic and magnetic ballasts. It keeps the environmental friendliness, long lifetime, reliability and robustness against extreme weather conditions of magnetic ballasts. Practical results obtained from large-scale installations have confirmed the advantages of the proposed technology.
