Abstract: A non-scattering light pipe (10) includes a transition surface (28, 30) between a first side wall (14) and an input suface (12) and a second side wall (16) and the input surface (12). The transition surface is arranged to substantially obscure the corner interfaces (36, 38) between the first and second side walls and the input surface such that in the corner formation any imperfections therein are not imaged into the output. Most preferably, the transition surface is optimized to provide a substantially uniform light intensity distribution. A light pipe in accordance with the preferred embodiments of the present invention is further arranged to couple a linear light source (306), such as a cold cathode fluorescent light (CCFL). The light source is arranged such that dim areas (337', 338'), i.e., areas of the light source having non-uniform intensity, are not disposed adjacent the input surface.

Abstract translation: 非散射光管（10）包括在第一侧壁（14）和输入表面（12）和第二侧壁（16）与输入表面（12）之间的过渡表面（28,30）。 过渡表面布置成基本上遮蔽第一和第二侧壁与输入表面之间的角接口（36,38），使得在角部结构中其中的任何缺陷不会成像到输出中。 最优选地，过渡表面被优化以提供基本均匀的光强度分布。 根据本发明优选实施例的光导管还布置成耦合线性光源（306），诸如冷阴极荧光灯（CCFL）。 光源被布置成使得暗区域（337'，338'），即具有不均匀强度的光源的区域不被布置在输入表面附近。
