Embodiment
See Fig. 1, coordinate see Fig. 2, Fig. 3, the present invention, with the reflective membrane of moth ocular structure, comprises pet layer 1, reflective structure layer 2 and moth-eye antireflection structure layer 3, reflective structure layer 2 is arranged on a side surface of pet layer 1, and moth-eye antireflection structure layer 3 is arranged on the opposite side surface of pet layer 1.
Reflective structure layer 2 in the present invention comprises resin bottom 21 and UV light curing resin layer 22, and resin bottom is attached on pet layer, and UV light curing resin layer is attached on resin bottom.
UV light curing resin layer in the present invention is pyramidal triangular pyramid structure, and three sides are mutually vertical, and bottom side length is 10mm-175mm.Bottom side length numerical value in allowed band is less, and reflecting rate is higher.
Above-mentioned pyramidal triangular pyramid structure is arranged according to rectangular array, and an array element is by four triangular pyramid Structure composing.As shown in Figure 3.
Moth-eye antireflection structure layer 3 in the present invention adopts class moth eye micro-nano structure, the characteristic dimension of such moth eye micro-nano structure is less than visible wavelength, be equivalent to a refractive index continually varying dielectric layer, can the loss of inhibitory reflex light in the spectral range of visible ray effectively.Such moth eye micro-nano structure is the cone of array arrangement, conical base diameter 200nm, high 200nm, and between adjacent circular cone, spacing is 300nm.Through further research, its scale Design should meet following rule: when cone base diameter is less than the lambda1-wavelength of 1/2nd, anti-reflection effect is best, and incident light is generally visible ray, and scope is 400nm-760nm.Cone basal diameter is less, and highly larger, namely depth-to-width ratio is larger, then anti-reflection effect is better.Spacing between array arrangement cone can affect moth ocular structure fill factor, curve factor, and spacing is larger, and fill factor, curve factor is less.Moth ocular structure fill factor, curve factor specifically refers to that in moth ocular structure, on a certain cross section, glue accounts for the ratio of the total area, and fill factor, curve factor is larger, and the equivalent refractive index on this cross section is more close to the refractive index of glue.The variation tendency of equivalent refractive index in moth ocular structure is milder, and the anti-reflection effect of moth ocular structure is better.
