Abstract
Abstract A light radiator unitarily comprising a movable light source corresponding to the direct solar rays and a fixed light source corresponding to the indirect solar rays. The light radiator comprises a transparent inner cylinder, a transparent outer cylinder accommodating the inner cylinder, and a light source device for guiding approximately parallel light rays into the inner cylinder and the outer cylinder from at least one end portion thereof. The inner cylinder contains therein dispersedly at a predetermined distance transparent bodies or semitransparent bodies for reflecting the light rays guided into the inner cylinder from the end portion thereof. A runner having a reflection surface for reflecting the light rays guided from the end portion is provided in a space between the inner cylinder and the outer cylinder. The runner is moved in the space therebetween along an axial direction thereof, and the light rays reflected on the reflection surface of the runner are reflected in the same direction as that of the light rays reflected on the transparent plate or the semitransparent plate in the inner cylinder.
