METHOD FOR MANUFACTURING A THREE-DIMENSIONAL REFLECTION MEMBER, AND THREE-DIMENSIONAL REFLECTION MEMBER THEREBY

摘要

The present invention discloses a method for manufacturing a three-dimensional reflection member for an illumination lamp and an LCD, and a three-dimensional reflection member thereby. The method for manufacturing a three-dimensional reflection member for an illumination lamp and an LCD comprises the steps of low temperature processing a resin film before the resin film is supplied to a forming part of a molding part; forcibly stretching the resin film by the coupling of the molding part when the low temperature processed resin film enters the forming part of the molding part to form a plurality of voids in the resin film and forming the resin film as a three-dimensional reflection member according to the shape of the forming part; and annealing the formed three-dimensional reflection member at the high temperature inside or outside the molding part to remove stress generated in the process of forcibly stretching the resin film. The present invention provides the three-dimensional reflection member for an illumination lamp and an LCD having high light reflection efficiency relatively to the existing three-dimensional reflector in the form of including or not including a light reflecting material therein.
