Abstract: An apparatus is provided, which has photocatalytic material coated on a surface thereof. The apparatus includes a member adapted to receive irradiation from a light source and a layer of photocatalytic material is formed on a surface of the member. The member having photocatalytic properties is adapted to be disposed in close proximity to the light source. In one embodiment, the photocatalytic member is positioned vertically on top surface of the housing of a fluorescent lamp unit such that the fluorescent tube surrounds the photocatalytic member. In another embodiment, the photocatalytic member is used as a lamp shade or a lamp cover to effectively utilize light emitted by a light source radiating light of appropriate wavelength.
