FIG. 1 is an overall view of an embodiment of a mounting reflector type air cleaner and an enlarged view of a cross section thereof. A layer 2 having a function of decomposing an organic substance by receiving ultraviolet rays is formed on at least a portion of the mounting reflector air cleaner 1 which is exposed to light.

収して伝導帯に励起 ラジカルが有機物と反応し、有機物を分解する。Titanium dioxide is used as a material of the layer 2 having a function of decomposing organic substances by receiving light. Among the optical semiconductors, titanium dioxide is particularly high in the oxidation catalytic action of the optical semiconductor, and titanium dioxide is also excellent in stability and safety. The mechanism for decomposing organic substances is assumed as follows. By irradiation with ultraviolet rays, electrons in the valence band of TiO2 absorb energy and are excited to the conduction band. The radicals react with organic substances and decompose the organic substances.

も煙りを捕らえることができる。The advantage of providing the photocatalyst layer on the mounting reflector for illumination as a key point of the present invention is that the photocatalyst layer can always receive a large amount of light without providing a new light source. A high photocatalytic effect can be obtained.
In recent years, usually in offices and homes, convection of air always exists in each room due to heating, cooling, ventilation fans, etc.Moreover, since the light source has heat, convection of air due to the Chimney effect emits light, It is always happening near the light source. Therefore, the photocatalyst layer can come into contact with air at a low wind speed. For this reason, organic substances, odor substances, and various germs are extremely efficiently adsorbed to the photocatalyst layer, and these adsorbed organic harmful substances are oxidatively decomposed by the photocatalytic reaction.
In addition, most of the lighting fixtures are located in the upper part of the room, and smoke such as cigarettes rises upward, so that smoke can be captured even when air convection is small.

い。[0012] Since the mounting reflector-type air purifier also has a function as an original reflector for lighting, the amount of illumination light can be increased without newly consuming power or increasing the number of lighting fixtures. . Since the reflection efficiency also decomposes organic matter (dirt) attached to the reflection surface, the action itself becomes a self-cleaning effect, and there is no decrease in illuminance due to deterioration over time.
【００１３】また、紫外線は吸収し、反射はしないの
で、店頭にある製品の色あせなどの軽減もできる。Further, since ultraviolet rays are absorbed and not reflected, it is possible to reduce fading of products in stores.

に、空気の清浄化もできる。The reflector type air purifier for mounting having the air purifying function is to be mounted in the immediate vicinity of the light source, and always receives strong light on the photocatalyst layer formed on the light receiving surface. Can be. Since the light source has heat, there is air convection due to the Chimney effect and air convection due to heating, cooling, a ventilation fan and the like in each room. Therefore, the photocatalyst layer can come into contact with air at a low wind speed. For this reason, organic substances, odor substances, and various bacteria are adsorbed to the photocatalyst layer very efficiently, and these adsorbed organic substances are oxidatively decomposed by the photocatalytic reaction. Therefore, no new energy is required, the efficiency of lighting can be increased, energy can be saved, and air can be purified.
