LIGHT REFLECTOR PLATE AND METHOD FOR MANUFACTURING THE SAME

摘要

An object of the present invention is to provide a light reflector plate having the following advantages A to D: A. no need for high initial investme nt for dies or the like required for forming a three-dimensional shape; B. simp le working and low cost of working; C. accurate shape retention of a reflector plate after bending work, and excellent dimensional stability even under severe conditions of use; and D. simple and low-cost attaching work for shap e retention. To achieve the above object, according to the present invention, narrow cuts 4 are intermittently formed in a light-reflecting plastic foam film or sheet 2 along straight lines in such a manner as to penetrate from one si de surface of the film or sheet 2 to the opposite side surface thereof. Subsequently the film or sheet is bent along the cuts.
