    • A lighting system has one or more light guides capable of guiding light, each comprising a core and two optically smooth faces. A cavity adjacent to two of the optically smooth faces has an opening and a reflective-transmissive surface opposite the opening. A cover having a light source is proximate to and occludes the opening. A major portion of any light emitted from the light source is reflected by the reflective-transmissive surface of the cavity and is injected into the light guides, and a minor portion of any light emitted by the light source is transmitted through the reflective-transmissive surfaces of the cavity and emitted from the lighting system. A light injection coupler is also disclosed that has an optically transmissive housing and suitable for use to couple ends of at least one light guide thereby making a lighting system.
    • 照明系统具有能够引导光的一个或多个光导体,每个光导体包括芯和两个光学平滑的面。 与两个光学平滑表面相邻的空腔具有与开口相对的开口和反射透射表面。 具有光源的盖子接近并遮住开口。 从光源发射的任何光的主要部分被空腔的反射透射表面反射并被注入到光导中,并且由光源发射的任何光的一小部分透射通过反射透射表面 并从照明系统发射。 还公开了一种光注入耦合器,其具有光学透射外壳并且适于用于耦合至少一个光导的端部,从而形成照明系统。
