Luminaire

A lighting fixture incorporates a peripheral light emission feature, such as a peripheral waveguide and/or a peripheral reflector region. A peripheral light emission feature may at least partially surround a non-peripheral feature that may include a light-transmissive panel. At least one first light source may illuminate a peripheral light emission feature, and at least one second light source may illuminate a light transmissive panel. Control circuitry is configured to selectively adjust intensity and/or color temperature of the light sources to cause aggregate emissions of the lighting fixture (or a lighting system with multiple lighting fixtures) to dynamically change over time (e.g., with different intensities and color temperature), so as resemble a skylight or window. A viewer may thereby perceive at least portions of a space as being naturally illuminated.

Lighting fixture with peripheral light emission feature

Generally, embodiment(s) disclosed herein may include modular luminaires and customizable luminaire combinations to produce desired overall illumination patterns, modular luminaires interchangeable between one or more lighting systems/luminaires having differing configurations, and/or luminaires with portions thereof formed primarily by optical waveguides, e.g., a wall sconce where primarily only waveguides extend from the wall. Further, contemplated throughout this disclosure is modification of panel-style and/or blade-style waveguide(s) for use with luminaire configurations having different sizes, shapes, and structural elements including as modular luminaires for use in creating further customizable lighting systems/luminaires.

Lighting fixture with waveguide

Luminaires are described herein comprising a single fixture operable for providing multiple lighting distributions. The multiple lighting distributions can be employed for independently lighting spatially unrelated areas and/or objects in an environment. In some embodiments, a luminaire comprises a lighting assembly including a primary body providing a primary lighting distribution, and at least one secondary body extending from the primary body and providing a secondary lighting distribution. The secondary body is adjustable to at least partially orient the secondary lighting distribution outside of the primary lighting distribution.

Luminaires having multiple lighting distributions

According to an aspect of the present disclosure, a luminaire comprises a housing and at least one waveguide comprising first and second opposite waveguide ends, a coupling portion disposed at the first waveguide end, and a light emitting portion disposed between the first and second waveguide ends. The luminaire is further arranged such that the first waveguide end is disposed adjacent a first luminaire end and the second waveguide end is disposed at a second luminaire end opposite the first luminaire end. Still further, the luminaire comprises at least one LED element disposed within the housing adjacent the coupling portion of the at least one waveguide such that the at least one waveguide provides a first illumination pattern and the at least one waveguide is interchangeable with another waveguide that provides a second illumination pattern.

Modular waveguides and fixtures utilizing same

An edge lit fixture. A light engine comprises a compartment and at least one elongated lens that are attachable to a mount plate. The mount plate, an exterior surface of the compartment, and the lens define an internal optical cavity. A light strip is mounted to the mount plate within the optical cavity. One or more legs can be used to attach the fixture to an external surface, such as a ceiling T-grid. The light engine can be used with legs of varying size such that it can fit within ceiling openings having different dimensions. The assembled fixture defines an open area. One or more light engines are arranged around or through the open area such that light is emitted into the open area. The open area of the fixture allows for existing materials, such as a ceiling tile, for example, to function as a back side reflector panel.

Edge lit fixture

Lighting retrofit systems and methods are disclosed that can be used with different light fixtures, but that are particularly adapted for use with retrofitting troffer-style fixtures with LED based light engines. The retrofit systems being assembled without disturbing the lighting or troffer pan or housing ('troffer pan') for the lighting system being retrofitted. Some of these embodiments can comprise a mounting fixture or frame that can be mounted in an opening in a ceiling grid, and held in place between the grid and the troffer pan edge. The fixture or frame can comprise an opening for a light engine, with the engine being quickly and easily connected to electrical power in the troffer pan and then mountable within the frame opening. These embodiments can allow for the quick and easy construction of the retrofit system without the need for adhesives and fasteners such brackets and screws.

Mounting system for retrofit light installation into existing light fixtures

A modular troffer-style fixture particularly well-suited for use with solid state light sources. The fixture comprises a reflector that includes parallel rails running along its length, providing a mount mechanism and structural support. An exposed heat sink is disposed proximate to the reflector. The portion of the heat sink facing the reflector functions as a mount surface for the light sources. The heat sink is hollow through the center in the longitudinal direction. The hollow portion defines a conduit through which electrical conductors can be run to power light emitters. One or more light sources disposed along the heat sink mount surface emit light toward the reflector where it can be mixed and/or shaped before it is emitted from the troffer as useful light. End caps are arranged at both ends of the reflector and heat sink, allowing for the easy connection of multiple units in a serial arrangement.

Modular indirect suspended/ceiling mount fixture

According to an aspect of this disclosure, a lighting system comprises at least first and second luminaires wherein each luminaire comprises a housing, an optical waveguide suspended from the associated housing, and one or more LEDs disposed adjacent the optical waveguide. Further in accordance with this aspect, the system comprises circuitry disposed within the housing of the first luminaire wherein the circuitry comprises LED driving circuitry and power circuitry, the power circuitry provides power to the first luminaire and at least a second luminaire, and the second luminaire is modular.

Modular lighting system

An edge lit fixture. A housing provides the basic shape and structure of the fixture. The housing is constructed from discrete segments including lens frames, side frames, and end frames, which can be used in many different combinations to create the desired fixture. The assembled housing defines an open central area. One or more light panels are arranged around the perimeter of the housing such that at least some of the light is emitted toward the central area. The open central area of the housing allows for existing materials, such as a ceiling tile, for example, to function as a back surface of the fixture.

portable social distancing devices are described herein which, in some embodiments, are wearable by a user to maintain proper social distancing in any environment. In one aspect, a portable social distancing device comprises a housing, a mounting assembly coupled to the housing, and a projection assembly comprising two or more adjustable light sources for projecting a visible perimeter a predetermined distance from the portable social distancing device. The two or more light sources, for example, can be independently adjustable along two axes.
