PROBLEM TO BE SOLVED: To provide a cap-type ultraviolet lamp that is worn on the head of a human. SOLUTION: A cap case 2, which houses an ultraviolet LED 3, a visible light LED 4, a helium neon laser or a power supply part 5 thereof is worn on the head of the man by a mounting band 7. A UV transmission filter 6 is mounted on the front of the cap case 2, and the injured surface of an examination target is irradiated with ultraviolet rays or a helium neon laser, by moving the head to detect flaws. Both hands become always free and both-hand work can be performed, while irradiating the examination target with ultraviolet rays, visible light or the helium neon laser. COPYRIGHT: (C)2006,JPO&NCIPI
