Abstract
PURPOSE: To form a reflector capable of providing diffusion reflection light at ease and at a low cost by setting the diffusion reflection part forming an annular uneven face centering the axis of a quadric surface of revolution on a top part side, and setting a flat mirror part on the adjoining projection opening part side. CONSTITUTION: A reflector 1 has a quadric surface of revolution, a diffusion reflection part 3 on the top part side of which an annular uneven face 2 centering the axis of the surface is formed is set, and a flat mirror part 4 and a lamp 5 set opposite to the reflector 2 are set adjacent to the reflector 3 on a projection opening part side. Since the reflector 2 has the quadric surface of revolution originally, the diffusion reflection part 3 is easily obtained just by setting a proper uneven face 2 so that a metal mold is easily manufactured. Since the projection opening part side is flat so that no working is required. Thereby, the reflector 1 can be easily formed by spinning work.
