摘要
通过实验研究了70W和150W中小功率陶瓷金卤灯的调光特性,详细讨论了调光后光谱的变化对光通量、显色指数和色温的影响。结果表明,在60%调光深度下,调光对陶瓷金卤灯的光效、显色指数、色温的影响不大。因此对小功率陶瓷金卤灯进行调光是可行的。
The dimming characteristics are investigated experimentally for small and medium wattage（70W, 150W） ceramic metal halide（CMH） lamps. The effects of dimming spectral distribution on luminous flux, CRI and ccT are discussed in detail. The results show that dimming has limited negative effects on CMH＇s luminous efficacy, CRI, CCT at 60% dimming depth. Therefore it is feasible to dim small wattage CMH.
