Brightness enhancement film using a linear arrangement of light concentrators
摘要：
A brightness enhancement article (30) provides light from a two-dimensional surface. The brightness enhancement article (30) has a plurality of light collecting structures (32), wherein each light collecting structure (32) is longitudinally extended in a length direction along the surface. Each light collecting structure (32) has an input aperture (33) optically coupled to a light-providing surface and an output aperture (35) distal from the input aperture (33), wherein the output aperture (35) has a surface area that is larger than the surface area of the input aperture (33). A pair of curved side walls (38) extend from the output aperture (35) toward the input aperture (33). In a cross section taken orthogonally with respect to the length direction, the curved side walls (38) approximate a parabolic curvature.

亮度增强制品（30）提供来自二维表面的光。 亮度增强制品（30）具有多个集光结构（32），其中每个聚光结构（32）沿着表面沿长度方向纵向延伸。 每个光收集结构（32）具有光学耦合到光提供表面的输入孔（33）和远离输入孔（33）的输出孔（35），其中输出孔（35）具有的表面积 大于输入孔径（33）的表面积。 一对弯曲的侧壁（38）从输出孔（35）朝向输入孔（33）延伸。 在相对于长度方向正交地截取的横截面中，弯曲侧壁（38）接近抛物线曲率。
