PURPOSE:To continuously change colors by providing light source devices for red, blue and green, optical fiber bundles for red, blue and green which are connected at one end to the light source devices emitting respective light rays and transmit the red, blue and green light rays from the light source device. CONSTITUTION:A red filters 7R is provided to the light source device 1R for red, a blue filter 7B to the light source device 1B for blue and a green filter 7G to the light source device 1G for green. The bundles 2R, 2B, 2G of the optical fibers are respectively fixed to the outside flank sides of the filters 7R, 7B, 7G and the red, blue and green light rays are conduced via the filters 7R, 7B, 7G to the optical fiber bundles 2R, 2B, 2G. The bundles 2R, 2B, 2G are bundled at the other end by a bundling means 3 and the bundles of the optical fiber bundles 2R, B, 2G are loosened. The optical fibers 4R, 4B, 4G to constitute the optical fiber bundles are uniformly mixed and bundled. The colors are thereby continuously changed.
