A light ray radiation device for use in medical treatment comprises an enclosed body having an inner surface capable of reflecting light rays and a cross-section made up of a polygon having an odd number of sides and an optical conductor for radiating visible light rays into the enclosed body. The device is constructed in such a way that the visible light rays can be reflected on the inner surface of the enclosed body and pass through the central portion of the enclosed body. |
