A luminaire for providing uniform illumination of a horizontal or vertical plane surface is provided with a reflector having three distinct contours to provide optimum distribution of light flux. The first section is cylindrical and extends from 117.degree. to 180.degree. from nadir. The second section is a general contour curve extending from 180.degree. to 270.degree. from nadir and is used to redirect flux in the zone from nadir to 65.degree.. The third section is a general contour curve extending from 270.degree. to 355.degree. from nadir and redirects the flux in the zone from 50.degree. to 65.degree. from nadir. The general contour curves in sections 2 and 3 are defined by fourth degree polynominal equations. |
