An air frame system includes a frame body defining one or more openings, a plurality of air passages along an inner periphery of the one or more openings, and an airframe grid coupled to the frame body. The airframe grid includes at least one wireway channel therein and a wireway channel cover clip is removably coupled to the at least one wireway channel. The air frame system also includes a light assembly removably coupled to the airframe grid, and a retainer clip removably coupled to the airframe grid. The airframe grid retains the light assembly within the airframe grid.

A system and method for a light panel assembly which is particularly useful for commercial horticultural applications. An extruded heat sink frame provides for a layered light panel assembly with superior heat dissipation characteristics and low power requirements while providing highly efficient returns and output radiant flux.

A modular fixture may include an LED light board and an LED driver positioned along a linear support structure, and includes at least two acoustic panels. The fixture further includes two-piece fasteners, some of which are positioned along the linear support structure, while others are positioned on an inward-facing surface of the acoustic panels. The two-piece fasteners are then able to removably secure the acoustic panels to the linear support structure.

A fluid-cooled LED-based lighting fixture for Controlled Environment Agriculture (CEA) to improve energy efficiency, recycle waste heat, and support the operation of environmental sensors in a controlled agricultural environment. In one example, a lighting fixture frame mechanically supports and houses respective components of the lighting fixture and includes a light spine to mechanically couple the lighting fixture to a support structure. One or more coolant pipes formed from copper and coupled to the lighting fixture frame conduct a fluid coolant through the lighting fixture to remove heat. The lighting fixture comprises one or more LED modules to emit light, one or more onboard sensors and/or cameras, wireless communication functionality, and multiple electrical power and communication ports to facilitate interconnection of the lighting fixture in a variety of controlled agricultural environments. In some examples, the lighting fixture includes a multispectral imaging system to acquire multispectral images of the environment.

Multi-function lighting fixtures are provided. In one example implementation, a lighting fixture may include an optical housing extending lengthwise between a first end and a second end. The optical housing may include a plurality of light sources disposed within an interior of the optical housing and a plurality of optical elements disposed along an exterior of the optical housing. The optical housing may also a plurality of compartments defined within the interior of the optical housing. Each of the optical compartments may be associated with a separate light source of the plurality of light sources and a separate optical element of the plurality of optical elements.

The present disclosure relates generally to a light emitting diode (LED) luminaire. In one embodiment, the LED luminaire includes an enclosure having an interior volume and a flat side along a length of the enclosure, wherein the flat side comprises an inside surface and an outside surface, wherein the enclosure comprises an extruded optically clear plastic and one or more LEDs coupled to one or more circuit boards, wherein the one or more circuit boards are mounted on the inside surface of the flat side of the enclosure.

An LED strip lighting fixture having an array of LEDs mounted on a frangible rigid aluminum base having a predetermined thickness, the thickness including predetermined points of weakness, whereby the rigid, preferably aluminum, base can be broken at the predetermined points of weakness. The rigid base has disposed thereon a laminated integrated circuit on which are mounted a plurality of electrical elements including a plurality of light emitting diodes in series electrical connection on the laminated integrated circuit whereby the frangible sections of the rigid base provide for easy customization in providing predetermined length dimensions of the rigid aluminum base and LED mounted lighting fixture. A secondary benefit of the interconnectability of the integral base and LED combination is that the heat of expansion and subsequent contraction of the metal base is accommodated by the mount and housing to reduce tick and ping noise.

A lighting device contains light-emitting elements and has an elongated shape. The lighting device has a housing that has reflective side walls extending in a longitudinal direction of the housing; a cavity formed between the reflective side walls; and light-emitting elements arranged at least partially along the longitudinal direction relative to each other in the cavity. An opening of the cavity forms a light-emitting area, A width of the cavity expands from the light-emitting elements towards the opening at least in sections. A reflective element covers at least a section of the opening and reflects a part of light emitted from the light-emitting elements towards the cavity and reduces a width of the light-emitting area compared to a width of the opening.

Light fixtures having light bar elements therein. In order to mimic the size and appearance of fluorescent bulbs in existing troffer-style and surface-mount fixtures, LEDs are may be arranged on light bars with integrated lenses to both diffuse the light and shape the output beam. One or more LEDs can be mounted, sometimes in clusters, along the length of a base of the light bar which can then be inserted into a fixture. An elongated lens is mounted to the base over the LEDs so that light emitted from the LEDs interacts with the lens before it escapes the fixture. These elongated lenses may be extruded from a diffusive material, for example, and can be shaped in various ways. For example, the lenses may be shaped to disperse more light to the sides, i.e., in a direction away from a normal axis that is perpendicular to the base.

Embodiments herein are directed to a lighting fixture for insertion into a strut channel member. In an installed position, a light source supported by the housing of the lighting fixture is disposed at least partially within an interior volume of the strut channel member. The lighting fixture can be attached to the strut channel member by the lips of the strut channel member. When the lighting fixture is installed in the channel member, light from the light source emanates in a direction out of the channel member through the slot in the channel member. The lighting fixture may be snapped or slid into or out of place in the channel member.
