摘要:
An optical system has a lightguide having a confinement direction and a first light source (202) disposed proximate a periphery of the lightguide (204). A light injector (216) is disposed to couple light from the first light source (202) into the lightguide (204). The light injector (206) has a surface formed with a confinement curve for confining light in the confinement direction. The light injector (206) may be disposed at either a recess (244) on the periphery of the lightguide or at a cut corner of the lightguide. A refractive structure, haying at least one surface non-perpendicular to an emission axis of the light source may be disposed between the injector and the lightguide. At least a portion of the injector (206) may have a shape corresponding to a confinement curve that is rotated about an axis parallel to the confinement direction.
摘要(中):
光学系统具有限制方向的光导和靠近光导(204)的周边设置的第一光源(202)。 设置光注射器(216)以将来自第一光源(202)的光耦合到光导(204)中。 光注射器(206)具有形成有用于将光限制在约束方向上的约束曲线的表面。 光注射器(206)可以设置在光导的周边上的凹部(244)处或光导的切割角处。 可以在喷射器和光导之间设置折射结构,其折射至少一个不垂直于光源的发射轴的表面。 喷射器(206)的至少一部分可以具有对应于围绕平行于约束方向的轴线旋转的约束曲线的形状。
