<p>PURPOSE:To reduce unevenness of light color by adjusting color of light emitted from a main light source by those of light emitted from auxiliary light sources. CONSTITUTION:A fluorescent lamp 1d for emitting light of white color as a main light source, and fluorescent lamps 1a-1c emitting lights of green, red and blue colors auxiliary light sources are housed inside a luminaire main body 8. A diffusing/transmitting plate 2 is disposed in the opening portion of the luminaire main body 3. The fluorescent lamps 1a-1c constitute an auxiliary light source group capable of obtaining mixed light of white color. The fluorescent lamp 1d for white color is placed beside the auxiliary light source group. The fluorescent lamp 1c for blue color having the smallest output luminous flux is interposed between the fluorescent lamps 1b, 1d each having a larger output luminous flux. With this arrangement, it is possible to increase a color mixture ratio without conspicuous unevenness of light color.</p> |
