Filed: 2001-10-02
Abstract: PROBLEM TO BE SOLVED: To provide a luminous joint making it possible to enjoy different designs depending on whether an ultraviolet LED is on or off, while also providing for antibacterial effects or the like using the effects of a photocatalyst. SOLUTION: Transparent silicone rubber 2 is blended with a phosphor 5 which emits light in response to ultraviolet radiation, so that, when an ultraviolet LED 3 fixed in the depth of the joint emits light, the phosphor emits light in its own phosphor color upon receiving the ultraviolet radiation. The luminous joints 1 emit light at a time, decorating areas around tiles 4. When the ultraviolet LEDs 3 are turned off, the luminous joints 1 return to the color of the transparent silicone rubber 2. By thus turning the ultraviolet LEDs 3 on and off, different atmospheres can be enjoyed. The ultraviolet radiation emitted from the ultraviolet LEDs 3 is transmitted through the transparent silicone rubber 2 and applied to the surfaces of the tiles 4 and the transparent silicone rubber 2.  The surfaces are coated with a titanium oxide photocatalyst 6 so that when the photocatalyst is activated by the ultraviolet radiation, the titanium oxide 6 exhibits antibacterial effects, antifouling effects, deodorizing effects, etc.
