LED luminaire with a cavity and finned interior

LED luminaire with a smooth outer dome and a cavity with a ridged inner surface

A lighting apparatus is provided with a first housing assembly formed from a thermally conductive material and a second housing assembly formed of a thermally conductive material. At least one electrical component is positioned within the first housing assembly and the at least one electrical component is in thermally conductive contact with the first housing assembly. At least one light source is in thermally conductive contact with the second housing assembly. The second housing assembly is not in thermally conductive contact with the first housing assembly, such that thermal energy from the first housing assembly does not directly transfer to the second housing assembly.

Lighting apparatus with reflector and outer lens

A luminaire comprises a frame and a plurality of optical waveguides retained by the frame. The optical waveguides bound a cavity, and each comprises: a top end and a bottom end opposite the top end; a coupling portion disposed at the top end; an inner side facing the cavity; and an outer side opposite the inner side. The inner and outer sides are disposed between the top and bottom ends. The luminaire further comprises at least one light emitting diode (LED) associated with each optical waveguide. Each of the LEDs are disposed opposite, and configured to direct light into, the coupling portion of the associated optical waveguide. Each optical waveguide is configured to receive the light via the coupling portion and emit the light primarily from the outer side.

Multi-waveguide LED luminaire with outward emission

A luminaire for use in lighting a large open space such as a parking lot or deck of a parking garage includes a plurality of optical waveguides disposed in side-by-side relationship and together defining a closed path and at least one LED associated with each optical waveguide and disposed at a first end of the associated optical waveguide.

Outdoor and/or enclosed structure LED luminaire

Outdoor and/or enclosed structure LED luminaire outdoor and/or enclosed structure LED luminaire having outward illumination

An optical waveguide comprising orthogonal x- and y-dimensions and developing an illumination distribution pattern comprising orthogonal x- and y-extents, comprising at least one coupling feature for directing light into the waveguide, at least one light redirection feature for redirecting light in an x-y plane within the waveguide, and at least one light extraction feature for extracting light out of the waveguide in an illumination pattern comprising at least one of the x- and y-extents that is offset with respect to the x- and y-dimensions, respectively. Additionally, the optical waveguide comprises optical features on at least first, second, and third sides thereof.

Luminaire utilizing waveguide

A light fixture including a mounting assembly for securing the light fixture to a static structure. The mounting assembly includes a gripper attachable to the static structure and a bar having a gripping region and a first end secured with respect to a main body portion of the light fixture. The mounting assembly may be adjustable such that the light fixture is held in a selected one of a plurality of possible orientations. In such embodiments, the gripper and the bar are configured for a finite number of the orientations such that the light fixture is held in a selected one of a plurality of orientations.

Light fixture

A luminaire with a plurality of optical waveguides disposed in side-by-side relationship, together at least partially defining a closed path, and a plurality of optical coupling portions disposed adjacent to the optical waveguides. Further, each optical coupling portion is associated with one of the optical waveguides, and each coupling portion includes a refractive portion and a pair of reflective portions disposed on opposite sides of the refractive portion. Additionally, at least one LED is associated with each optical coupling portion and disposed at a first end of the associated optical coupling portion.

A luminaire includes a housing, an optical waveguide disposed in the housing comprising a plurality of light coupling cavities, and a plurality of LEDs disposed in the housing adjacent the plurality of coupling cavities. A mounting apparatus is adapted to mount the luminaire on a roadway stanchion.
