Abstract: A light directing optical structure is formed of a light waveguide (40) preferably made of clear plastic; attached to or formed with the waveguide are a multiplicity of prisms (42). Each prism (42), due to its index of refraction, provides an aperture where light may escape the waveguide (40) rather than remain confined due to total internal refraction. The light escaping the waveguide (40) is reflected from a side face (32) of the prism (42), and redirected in a desired direction. The propagation paths within the waveguide (40) are such that the light emerging through the aperture is of only a fairly closely constrained range of angles; as a result the light that is redirected by the side face of the prism is of a similarly constrained range of angles. The geometry of the prism (42) can be optimized to direct the output light perpendicular to the plane (33) of the waveguide (40), or at a desired angle other than perpendicular. The optical structure can receive a light input along an edge, or along several edges, and its output beam is perpendicular to the structure or at some desired angle other than perpendicular. There is no restriction on the distribution and uniformity of the light input, yet the output is a directed and intensity controlled light source. Configurations are disclosed adapting the structure to several different possible light distribution patterns.
Abstract translation: 光引导光学结构由优选由透明塑料制成的光波导（40）形成; 与波导连接或形成有多个棱镜（42）。 由于其折射率，每个棱镜（42）提供了光，其中光可以从波导（40）逸出，而不是由于内部全折射而保持约束。 离开波导（40）的光从棱镜（42）的侧面（32）反射，并沿所需方向重新定向。 波导（40）内的传播路径使得通过孔径出射的光仅具有相当接近的角度范围; 结果，由棱镜的侧面重定向的光具有相似的约束的角度范围。 可以优化棱镜（42）的几何形状以引导垂直于波导（40）的平面（33）的输出光，或者以除垂直之外的期望角度引导。 光学结构可以沿着边缘或沿着几个边缘接收光输入，并且其输出光束垂直于该结构或者在除垂直之外的某个期望的角度处。 对光输入的分布和均匀性没有限制，但输出是有针对性和强度受控的光源。 公开了配置，使结构适应几种不同的可能的配光模式。
