在现有的投影过程中, 多个高功率投影机将高流明的光束直接地聚焦至 楼宇上, 在楼宇的墙壁和玻璃窗上形成艺术造型或影像。 在投影时, 砂砾墙 壁的楼宇存在反光率较低以及成像质量较差的问题; 玻璃幕墙的楼宇存在镜 面反射率和透射率高(光线折射到天空和透射至楼宇内部)的问题,严重时, 砂砾墙壁的楼宇和玻璃墙壁的楼宇成像质量很差, 甚至根本不能成像。
为了降低成本和提升投影质量,人们制作出了反光膜(例如铝箔反光纸),
反光膜的表面可以形成漫反射, 通过将反光膜贴置于楼宇的玻璃窗上, 可以 大幅度提高楼宇的反光率, 因此对投影机功率的要求则大幅度降低。
然而, 上述反光膜又存在透光率差的问题, 在白天办公时, 由于光线无 法透过反光膜进入楼宇内部, 因此楼宇内部的光照度较低, 影响了正常办公 和人们对阳光的基本需求。

在表 1中, 各投影成像膜的基膜层的材质为白色 PVC材料, 为了衡量 摩尔纹的对显示图像的影响, 按影响程度的从高到低依次划分为以下五个等 级: 严重、 强、 较强、 较轻和无。
依据仅分析单一变量,保持其余各个变量均不变的对比分析原则对测试 数据进行分析, 可以得到以下规律:
第一、 摩尔纹的严重性和孔边距成反相关, 即孔边距越小, 摩尔纹越容
易发生。 在其它参数不变的情况下, 不能够一直通过增加孔边距来抑制摩尔 纹的产生, 因为孔边距越大, 建筑玻璃幕墙投影成像膜的透光率则越差。
第二、摩尔纹的严重性和通光孔的直径成正相关,即通光孔的直径越大, 摩尔纹越容易发生, 视觉感受越明显。
第三、 漫反射涂层能够抑制摩尔纹的产生, 其中 1号膜和 2号膜没有设 置漫反射涂层, 其余四个膜设置有漫反射涂层, 比较时仅分析单一变量, 保 持其余各个变量均不变, 例如对 2号膜和 3号膜进行对比, 可以得知增加漫 反射涂层对摩尔纹的影响。
本实施例的建筑玻璃幕墙投影成像膜综合考虑了反光性、 透光性、 色彩 饱和度、 对比度、 增益、 视角范围以及摩尔纹抑制率等各项光学参数, 适用 于近距离投影、 中距离投影和远距离投影。 另外, 由于通光孔的孔径仅为 1 毫米, 因此投影图像的像素损失率也较低。
本实施例的建筑玻璃幕墙投影成像膜的具有以下替换结构:
实际制作时, 该些透光基元的面积可以为 0.07mm2至 2mm2, 较佳地, 该些透光基元为通光孔, 通光孔的孔径可以为 0.7毫米至 1.6毫米, 相邻的 两个通光孔的孔边距可以为 0.15毫米至 0.5毫米, 更佳地, 通光孔的孔径可 以为 0.8毫米至 1.4毫米, 相邻的两个通光孔的孔边距可以为 0.2毫米至 0.4 毫米。 通光孔的形状不必局限为圆形, 椭圆形或正多边形的通光孔也可以达 到透光的目的。 除了应用于建筑玻璃幕墙, 投影成像膜还可以贴在建筑楼宇 砂砾墙面、 大理石墙面、 铝板墙面等各种材质的墙面上, 以便提高墙面的投 影成像质量。
实施例 2
本实施例的建筑玻璃幕墙投影成像膜与实施例 1的建筑玻璃幕墙投影成 像膜具有多个相同之处, 这些相同之处不再赘述, 然而, 请结合图 6予以理 解,本实施例的建筑玻璃幕墙投影成像膜 3与实施例 1的建筑玻璃幕墙投影 成像膜的不同之处在于: 基膜层上阵列有多个通光孔, 该些通光孔并非完全
行列对正, 相邻两行的通光孔相互错开。
实施例 3
本实施例的建筑玻璃幕墙投影成像膜与实施例 1的建筑玻璃幕墙投影成 像膜具有多个相同之处, 这些相同之处不再赘述, 然而, 请结合图 7予以理 解,本实施例的建筑玻璃幕墙投影成像膜 4与实施例 1的建筑玻璃幕墙投影 成像膜的不同之处在于: 透光基元不必局限为通孔, 实际制作时, 基膜层可 以制作成黑白相间的围棋盘样式的基元形状, 该些透光基元为白色透光部分, 该些反光基元为银黑色的反光部分, 此时白色透光部分只需要透光即可根本 不需要冲孔。
虽然以上描述了本发明的具体实施方式,但是本领域的技术人员应当理 解, 这些仅是举例说明, 在不背离本发明的原理和实质的前提下, 可以对这 些实施方式做出多种变更或修改。 因此, 本发明的保护范围由所附权利要求 书限定。
