摘　　要：HID(高强度气体放电)灯的亮度比传统的卤素灯高2～3倍,工作寿命更是高出10倍有余,色温在4000～12000K,接近日光。HID灯适用范围广,在室内室外体育场馆、汽车甚至消防照明领域都能见到其身影,其卓越的显色性使其在高档奢侈品商店的照明中占有不可动摇的位置,目前在欧洲对HID氙气灯的需求正以每年13%的速度增长。然而这一切也对如何保证HID灯正常稳定工作提出了相当苛刻的要求,为此,针对HID电子镇流器的研究一直是一个重点。不同于目前市场上大部分厂家的电子镇流器,本文提出了一套低成本、高可靠性的真正意义上基于HID灯自身功率控制的电子镇流器。Compared to the traditional halogen lamps, HID lamps have much higher luminance and longer life time. Their color temperature are around 4 000 - 12 000K, very close to the sun light. Thus, HID lamps have a very wide use including illumination of indoor and outdoor stadium, fire fighting etc. Large numbers of luxury shopping malls use HID lamps as their major means of illumination because of the high color rendering index of HID lamps. Nowadays, the demands of HID lamps still maintain a high increasing, about 13% per year, in Europe. But all mentioned above must be based on the stable working of HID lamps. So the study for HID ballast is always the key to the improvement. Different from the major ballasts in the market, this article proposes a high reliable ballast which has a real power control for HID.
