PROBLEM TO BE SOLVED: To eliminate causes of the generation of ozone, hurt to the skin, etc., and to enable simple application to a open system by a method in which a photocatalyst is stuck to a prescribed position of a movable body, and the movable body is irradiated with light of wavelength in a specified range by a light source from a prescribed position. SOLUTION: A driving source 1 consisting of a motor, etc., is suspended and supported from a ceiling by a support member 2, and a photocatalyst 4 is stuck to a prescribed position of the lower surface of a movable body 3 as the blade of a ceiling fan which is rotated and driven by the driving source 1. A light source 5 and a reflecting mirror 6 are suspended and supported below the driving source 1, and the photocatalyst is irradiated with direct light of 300-400nm from the light source 5 and reflected light from the reflecting mirror 6. In this way, a catalytic effect of the photocatalyst 4 can be demonstrated efficiently, and the simple application to an open system is made possible without causing the generation of ozone, hurt to the skin, etc. |
