The surface of shape wave curved surface is seamlessly transitted successively by crest, trough.
Described substrate layer is the enhancing specular reflection film of 32 70 microns of gross thickness, and described enhancing specular reflection film is
Polyethylene terephthalate film more than two-layer, described polyethylene terephthalate film thickness in monolayer is more than or equal to
The a quarter of optical wavelength.
The crest of described smooth waveform curved surface longitudinal section, trough are circular arc line, parabola, hyperbola, in sine curve
One or more.
The described coat of metal is monolayer silver coating or aluminium coated or copper plate or Gold plated Layer or zinc coat.
The described coat of metal is the MULTILAYER COMPOSITE layer of silver coating or aluminium coated or copper plate or Gold plated Layer or zinc coat.
