摘要： Luminaires are described herein employing waveguides and associated architectures for dynamic alteration of illuminance distribution patterns. The waveguide includes a light extraction component. The waveguide transmits light from a light source to the light extraction component by total internal reflection (TIR). The light extraction component includes one or more reversibly moveable surfaces for altering illuminance distribution patterns of the luminaire in response to one or more forces applied to the light extraction component by a force application assembly of the luminaire.

摘要： A waveguide body comprises a length from a first end to a second end along a longitudinal axis, and a coupling portion that comprises first and second coupling surfaces. The first and second coupling surfaces define, at least in part, an elongate coupling cavity along the entire length of the waveguide body and a surface located opposite the coupling cavity. The waveguide body further comprises first and second opposed sections extending along the length of the waveguide body. The first and second opposed sections further comprise respective first and second lower surfaces disposed at different first and second side section angles with respect to a first axis lying in a plane normal to the longitudinal axis. The first axis bisects the coupling portion. Among other things, such a waveguide may be included in a luminaire along with a light source.

摘要： A luminaire having a waveguide suspended beneath a mounting element, the waveguide has a first surface proximal to the mounting element, a second surface distal to the mounting element, and an edge between the first and the second surfaces. At least one cavity extends into the waveguide from the first surface to the second surface. A LED component is coupled to the waveguide so as to emit light into the cavity. LED support structures are also disclosed.

摘要： Luminaires are described herein employing waveguides and associated architectures for dynamic alteration of illuminance distribution patterns. In one aspect, a luminaire described herein comprises a waveguide body and light sources having differing angular positions relative to the waveguide body for altering illuminance distribution patterns of the luminaire according to one or more activation patterns of the light sources. The differing angular positions can be located at the perimeter of the waveguide body and/or at one or more internal locations of the waveguide body.

摘要： According to one aspect, a waveguide comprises a waveguide body having a coupling cavity defined by a coupling feature disposed within the waveguide body. A plug member comprises a first portion disposed in the coupling cavity and an outer surface substantially conforming to the coupling feature and a second portion extending from the first portion into the coupling cavity. The second portion includes a reflective surface adapted to direct light in the coupling cavity into the waveguide body.
