<P>PROBLEM TO BE SOLVED: To provide a lighting fixture for discovering fine dirts which can easily discover fine dirts, which is gentle to health of a worker as compared with a conventional case wherein a high luminance light source is used for discovering dirts giving severe fatigue to worker's eyes. <P>SOLUTION: In the wheeled lighting fixture for dscovering dirts, wheels 5 of the same diameter are arranged in parallel inside or outside of a casing or a frame composing a lighting fixture; a light source 1 is used in which several pieces of optical fibers 2 are used, can irradiating a horizontal contact face light to a space width between the wheels with wheel widths themselves of the wheels excluded; and an irradiation plate B in which the bundled optical fibers 2 are aligned tight in a horizontal row and a cylindrical lens 3 is integrally mounted on a front face of an irradiation port formed in a planar shape is provided on a lower face or a side face of a wheel axle. Thereby, an inclination angle of the irradiation plate B, or an irradiation angle of the light irradiated from the irradiation port can be easily changed with the installation face of the wheels 5 as a fulcrum and moreover a work face C can be observed while moving. <P>COPYRIGHT: (C)2012,JPO&INPIT |
