0　前言荧光灯显色性的改善主要取决于所用荧光粉材料。紧凑型荧光灯由于采用稀土激活的三基色荧光粉,其显色指数达到80以上。尽管显色性可以得到改善,但荧光粉的价格太高,难以在普通荧光灯中大量推广。卤粉价格便宜,但发射光谱缺乏长波段的宽带红光,显色性较差。为弥补荧光灯? 0 Introduction The improvement of the color rendering of fluorescent lamps mainly depends on the phosphor material used. Compact fluorescent lamps due to the use of rare earth activated trichromatic phosphors, the color rendering index of 80 or more. Although the color can be improved, but the price of phosphor is too high, it is difficult to promote a large number of ordinary fluorescent lamps. Halogen powder cheap, but the lack of long-wavelength broadband emission spectrum of red light, poor color rendering. To make up for fluorescent light?
