PURPOSE: To improve the external outward appearance of a lighting fixture to an extremely high level by a lens step provided on the lens of the lighting fixture. CONSTITUTION: Projected and recessed fisheye steps 11 and 12, arrangedly formed in a row direction respectively, are arrayed in a row direction one row by one row respectively on the inner surface of a lens 5A, mounted on a lighting fixture body and for radiating light, from a light source mounted on a lighting fixture body, outward; and respective steps are arrayed while being shifted by 1/2 pitch in a row direction. An optical image, formed by the respective steps, is made to be different in the fore and aft direction of a lens surface, that is, that of a lighting fixture, to cause a depth in the optical image to increase the stereoscopic effect of a lens, thereby improving the external outward appearance of the lighting fixture; and the height difference between both the steps is reduced to facilitate forming. |
