Reflector for Lighting and Back Light Device for Displaying Information

摘要

It is an object of the present invention to provide a reflector for lighting which has shape holding property, flexibility and lightweight property. That is, a reflector for lighting of the present invention comprises: a reflective material 1 made of a polymer membrane of which an average reflectance of 400 to 700 nm wavelength of at least one surface side is 85% or more and having a ridge-shaped uneven shape; and a reinforcing material having flexibility, and the reinforcing material connects the bottom parts of concave parts with each other from the back side of the one surface side of the reflective material 1 to reinforce the uneven shape.
