1. A lighting fixture comprising:
- a set of frame members each having a contour defining a concave curve, the set positioned at parallel, spaced apart positions;
a reflector having an outer reflective surface and an inner surface, the reflector being placed across the contour of each frame member with the reflective surface facing outwardly and assuming the concave curve of the contour;
a securing member connected to the frame members and having a portion which abuts the reflective surface and applies retaining force against the reflector to secure the reflector to the frame members, the securing member including an adjustment to provide varying clamping force against the reflector;
a light source holder connected to at least one frame member and positioned in front of the reflective surface of the reflector.

Abstract
A reflector used in a lighting fixture wherein a relatively thin, flexible, reflecting surface is placed against a precisely formed curve in a frame. The reflecting surface is then clamped against the precisely formed curve and adopts the shape of precisely formed curve. A method according to the invention cuts the precisely formed curve from a piece and then uses both parts of the piece to clamp the reflective surface in place. It is preferred that the reflective sheet be placed against and clamped at least at opposite edges.

11. A reflector for providing a precise curvature for a reflecting surface comprising:
-
a frame; the frame including first and second, spaced apart, parallel, and identical receiving surfaces, each receiving surface defining a precise curve; first and second clamp members, each having a mating surface that precisely mates with the precise curve of the receiving surfaces; a reflector removably positionable between the receiving and mating surfaces of the frame and clamp member; securing members connectable between the frame and clamp members, the securing members being adjustable to move the clamp members closer or farther from the receiving surfaces. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
