Patent

CA 2493425

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 investment for dies or the like required for forming a three-dimensional shape; B. simple 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 shape 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 side surface of the film or sheet 2 to the opposite side surface thereof. Subsequently the film or sheet is bent along the cuts.

L'invention concerne une plaque de déflexion optique possédant les avantages A D suivants. A. Il n'est pas nécessaire de disposer d'un moule initialement coûteux, ou analogue, afin de réaliser une forme tridimensionnelle. B. Le traitement est simple et son coût est faible. C. La forme de la plaque de réflexion après cintrage peut être maintenue avec précision et, en outre, cette plaque possède une stabilité dimensionnelle supérieure même en cas de conditions d'autonomie. D. Le procédé de traitement de fixation destiné à maintenir la forme est simple et de coût faible. Afin de réaliser l'objet ci-dessus, on forme de façon intermittente des coupes étroites, le long de lignes droites, passant d'une surface d'un côté à la surface de l'autre côté d'une feuille ou d'un film de plastique en mousse réfléchissant la lumière. Puis, on cintre le film ou la feuille le long des coupes.
