ABSTRACT:
A lighting apparatus including a tubular light source and a member having a plurality of reflective surfaces which are angularly set such that light from the light source is reflected in a predetermined direction of a viewing angle by each of the reflective surfaces. A ratio of an apparent width of each of the reflective surfaces to an apparent interval of adjacent ones of the reflective surfaces, when viewed from the predetermined direction of the viewing angle, is so set as to be a function of a distance between the light source and each of the reflective surfaces.
