PURPOSE: To improve advertising effect by providing reflection mirrors rotated by drive devices in a light transmissive tube, providing a light source in one longitudinal end part of the light transmissive tube, and providing optical fibers between irradiation ranges of the light source and the reflection mirrors. CONSTITUTION: In this light, light of a lighted light source 6 is irradiated onto a colored filter 18 radially divided into plural blocks 18a-18e and rotationally driven by a motor 17. Light receiving parts 11 of optical fibers 10 receive the variously colored light to emit the light from irradiation parts 12a, 12b. Drive devices 9 respectively rotate reflection mirrors 8 vertically disposed in series within a light transmissive tube 5 rotated by a drive device 4. The colored light emitted from the irradiation parts 12a, 12b is reflected by the reflection mirrors 8, and is irradiated onto the light transmissive tube 5 to be radially transmitted outward from plural vertical positions. |
