中文摘要 | 調光式電子安定器的基本原理是利用變頻方式調整電子安定器的輸出 功率,從百分之十到全功率之間做線性變化,而使得螢光燈的亮度在這線性操作 範圍內做柔和的改變,以達成滿足使用者對不同亮度的需求為目的。 |
英文摘要 | The operation principle of dimming electronic ballast is based on frequency adjustment of the resonant circuit which in turn controls the magnitude of the ballast outputpower. It is designed to deliver output power in the range of ten percent to full power ina continuous fashion that enable the brightness of fluorescent lamps to changesmoothly. The dimming electronic ballast is able to offer much more suitable andcomfortable illumination in different environment that traditional ballast can notafford. Through automatic tuning, the dimming ballast also provide significant energysaving that represents huge market potential in the lighting world of tomorrow. |
