In view of these reasons, outside conventional chamber, under the situation of signboard, mainly use by polycarbonate (polycarbonate; PC) diffuser plate processed of resin, said polycarbonate resin has good shock resistance; And, under the situation of indoor signboard, be widely used by polymethylmethacrylate (polymethylmethacrylate; PMMA) diffuser plate processed of resin, said plexiglass has good plasticity-.Now, use the diffuser plate of PMMA resin generally to be used for outdoor signboard, the thickness of said PMMA resin increases to improve shock resistance.
As shown in Figure 1, diffuser plate 2 is used for signboard 1, so that advertising printing is attached to the surface on thin plate and with thin plate, said diffuser plate 2 is mainly processed by lighttight acryhic material or PC resin.In addition, as shown in Figure 2, the diffuser plate that is used for means of illumination 3 is used for radiative light-emitting device (not shown) as lid 4 or box with protection, and said diffuser plate comes the light of selfluminous device also as scatterer with diffusion.
In addition, diffuser plate be used for display unit (such as, watch-dog, televisor etc.) situation under, this is an important use of light diffusing sheet, diffuser plate is generally processed by the PS with plate shape (PS) resin.
Yet the PC resin that is used for indoor and outdoor illumination and signboard is costliness, and the PC resin can not form different shape, because relatively poor Mould Machining performance.Under the situation of acryhic material, price is low but acryhic material has lower intensity and lower transmittance and diffusivity.Therefore, the distance that the diffuser plate of being processed by acryhic material should be predetermined at interval with light, therefore said diffuser plate occupies than large space.
Therefore in addition, the PS resin has good transmittance and diffusivity, but the shock strength of PS resin is lower than the shock strength of acryhic material, said PS resin and not being suitable in existing means of illumination or the signboard.
Summary of the invention
