PROBLEM TO BE SOLVED: To provide a compact fluorescent lamp for photographing capable of obtaining an image same as that taken in natural light although distribution of spectrum is quite different from that of natural light, by tactfully selecting the kind of phosphor out of wide-ranged heat resistant phosphors. SOLUTION: The phosphor contains at least one kind selected from europium-activated aluminate phosphor, or europium, manganese-activated aluminate phosphor, or europium-activated halophosphate phosphor; at least one kind selected from cerium, terbium-activated lanthanum phosphate, or terbium-activated cerium, magnesium aluminate phosphor, or cerium, terbium-activated gadolinium, magnesium borate phosphor; and cerium, manganese-activated gadolinium, zinc, magnesium borate phosphor. The color of the light is constructed so as to be in a circle having a radius of 0.004 with a point of u=0.218, v=0.316 as a center, on a chromaticity coordinate. COPYRIGHT: (C)2006,JPO&NCIPI
