摘要： A lighting assembly includes a light guide and light source. The light guide includes light input regions, at least one of the light input regions associated with an optical modifying characteristic, and the light guide is configured to propagate light by total internal reflection. The light source is located adjacent the light input regions. The light source and light input regions are variably positionable relative to one another to vary a location at which light is incident on the light input regions such that light emitted from the light source is selectively apportioned between the light input regions. A characteristic of the light output from the lighting assembly is modified based on the optical modifying characteristic of the at least one of the light input regions and the relative positioning of the light source and the light input regions.

摘要： A lighting assembly includes a light guide having opposed major surfaces between which light propagates by total internal reflection and a light input edge. The light assembly also includes a light engine. The light engine has a heat conductive armature having a receptacle for a portion of the light guide that includes the light input edge and a light source retained by and thermally coupled to the armature. The armature functions as a heat sink for dissipating heat generated by the light source. The light guide is mechanically retained in the receptacle, and the light guide and the armature cooperate to align the light input edge with the light source for inputting light from the light source into the light guide through the light input edge.

摘要： A lighting assembly includes a light guide to propagate light by total internal reflection and having a light output region on a major surface thereof. The lighting assembly also includes an optical adjuster having a major surface juxtaposed with and conforming to the light guide's major surface. The optical adjuster has a first region and a second region, the first region having a light modifying characteristic. The optical adjuster and light output region are variably positionable relative to one another to selectively apportion light emitted from the light output region between the first region and the second region. In this way, light apportioned to the first region is modified by the light modifying characteristic so that light output from the lighting assembly is modified based on relative positioning of the optical adjuster and the light guide.

摘要： A lighting assembly includes a light guide having opposed major surfaces between which light propagates by total internal reflection, a light input edge, and two light output regions of different optical characteristics and at least one of which is associated with a corresponding one of the major surfaces. The lighting assembly also includes a light source located adjacent the light input edge. The light source and the light guide variably positionable relative to one another to vary a location on the light input edge at which the light is input to the light guide such that the light is emitted from the light guide selectively apportioned between the light output regions so that a characteristic of the light output from the lighting assembly is modified based on the optical characteristics associated with the light output regions and the relative positioning of the light source and the light guide.

摘要： A lighting assembly includes a light guide and a light source. The light guide has opposed major surfaces and side surfaces extending between the major surfaces. The light source is at an apex region between two side surfaces and is configured to input light to the light guide. The side surfaces comprise a stepped reflective side surface extending from the apex region and comprising a first reflective step and a second reflective step, and an output side surface extending from the apex region and comprising a first output region and a second output region. The first reflective step is configured to reflect a first portion of input light through the first output region. The second step is configured to reflect a second portion of input light through the second output region. The second output region comprises segments oriented nominally normal to the reflected second portion of the light incident thereon.

摘要： A lighting assembly includes a transparent light guide having a first major surface, second major surface, and light input edge, and is configured to propagate light by total internal reflection. A light source located adjacent the light input edge is selectively operable to edge light the light guide. First light extracting elements at the first major surface are configured to extract light through the first major surface with a first light ray angle distribution. Second light extracting elements at the first major surface are configured to extract light through the second major surface with a second light ray angle distribution. The light extracted through the second major surface reduces visibility at viewing angles within a defined viewing angle range through the lighting assembly from the second major surface of the light guide greater than the reduction in visibility through the lighting assembly from the first major surface of the light guide.

摘要： A lighting assembly has a light guide (120) with light guide portions (LGPs, 122, 124) each having a distal edge (134, 144) and a castellated proximal edge (136, 146) in which first edge segments (150, 160) alternate with second edge segments (152, 162) that are offset from the first edge segments towards the distal edge. The LGPs are arranged with the first edge segments of one abutting the second edge segments of the other. Each LGP tapers such that it is thicker than the other at its first edge segments to define respective light input edge segments. Respective solid-state light emitters are located adjacent the light input edge segments of each LGP to input light to the LGP. The light propagates along the LGP by total internal reflection at the major surfaces thereof. Each LGP additionally includes light extracting elements at at least one of its major surfaces to extract light through the front major surface thereof.
