Method for making a reflector for a luminaire

Abstract

This method for making a luminaire reflector comprises: (a) providing a sheet of metal having two generally parallel edges and a mid-plane extending perpendicular to said edges; (b) cutting from this sheet a blank that comprises (i) two primary portions, each in the shape of a trapezoid having a major base extending along one edge of the sheet, a minor base spaced from the major base, side edges extending between the ends of the major and minor bases, (ii) a junction portion interconnecting the minor bases, and (iii) end-paneling portions at opposite sides of the mid-plane, each of the end-paneling portions comprising a plurality of sections, one section joined to a side edge of one of the primary portions, another section joined to a side edge of the other primary portion and a third section joined to the junction portion. The method further comprises the additional steps of: (a) bending the blank into a U-shaped form wherein the primary portions constitute the arms of a trough-shaped reflector body, and the junction portion forms a bight joining the arms at one end of the arms, and (b) bending the blank at each of the side edges where an end paneling section is joined to a primary portion and where each of the third sections is joined to said junction portion so that the sections of end paneling at each side of the mid-plane meet to form an end wall of the reflector.
