<P>PROBLEM TO BE SOLVED: To make light emitting members emit light freely when desired, and to obtain those excellent in coloring and decorativeness. <P>SOLUTION: Between 1st and 2nd light emitting members 10, 15 emitting light reacting to infrared rays, an ultraviolet ray shielding filter 12 is arranged, which prevents the 2nd light emitting member 15 being irradiated with the ultraviolet rays from a 1st ultraviolet ray emitting element 11 and also prevents the 1st light emitting member 10 from being irradiated with the ultraviolet rays from a 2nd ultraviolet ray emitting element 14. Therefore, the 1st and 2nd light emitting members can be made to emit light freely when desired by making the 1st and 2nd ultraviolet ray emitting elements 11, 14 emit light, and also either of the 1st and 2nd light emitting members 10, 15 can be made to emit light selectively, whereby the 1st and 2nd light emitting members 10, 15 become abundant in combinations of their light emitting states colors rich in coloring decorativeness can be obtained. <P>COPYRIGHT: (C)2003,JPO |
