Reflective film structure for preformed structural element

A reflective film structure, adapted for being adhered and shaped on a plurality of processing surfaces of a preformed structural element, wherein the processing surfaces form a three-dimensional shape, the reflective film structure comprising:

• a thermoplastic adhesive film with a thickness ranging from 0.01 mm to 1 mm, having an internal surface and an external surface, wherein the internal surface is adhered to the processing surfaces of the preformed structural element;
• and
• a reflective layer, laminated on the external surface of the thermoplastic adhesive film, having a plurality of beads distributed on an outer surface of the reflective layer,
• wherein the reflective film structure has a normal direction vertical to the reflective layer, the reflective layer has at least a first reflective region and at least a second reflective region that have different directions and are respectively towards different directions other than the normal direction, and the first reflective region and the second reflective region are respectively disposed with at least one of the beads.
