A structural light fixture for the ceiling of clean room, such as a clean room for pharmaceutical or electronic research or production, includes an outer U-shaped beam and an inner U-shaped beam. The inner U-shaped beam nests within the outer U-shaped beam. The inner and outer U-shaped beams are mutually reinforcing so that the combination of the two U-shaped beams is stronger and stiffer than either U-shaped beam alone. The top side of the outer U-shaped beam is exposed to the outside of the clean room and includes no perforations so that the outer U-shaped beam is a barrier to gas, particulates, microorganisms or disinfectants that otherwise would pass through the clean room ceiling. The removable inner U-shaped beam includes a lamp and power supply, allowing maintenance of the structural light fixture from the interior of the clean room without interrupting the barrier to contamination created by the structural light fixture.

A custom LED lighting fixture system has a planar opaque top element and an opposing planar translucent bottom element that can be custom fabricated to take any number of shapes. Upon fabrication of the top and bottom elements into an irregular circumferential shape, for example, a first aluminum extrusion is fitted to the left side, and a second aluminum extrusion is fitted to the left side. The first and second extrusions adapt to the shapes of the top and bottom elements. The extrusions comprise a first channel on the interior surface configured to accept the top element, and a second channel configured to accept the bottom element. A first end cap couples to a first end of the first and second extrusions. A second end cap couples to a second end of the first and second extrusions. An LED strip is operational on an interior surface of the top element.

A luminaire comprising: a chassis (100), the chassis (100) comprising: four walls joined to form a rectangular cavity, each wall of the four walls comprising: —a heat sink (107); —a wiring channel (111, 112); —a first receiving channel (114) on a first side of the heat sink (107); and —a second receiving channel (116) on a second side of the heat sink (107); a light emitting diode board (130) attached to a first wall of the four walls; a first extrusion (344) attached to a second wall of the four walls; a second extrusion (345) attached to a third wall of the four walls; wherein the light emitting diode board (130) comprises a first protrusion that fits into the first receiving channel and a second protrusion that fits into the second receiving channel; and wherein the light emitting diode board (130) rests on the heat sink (107) of the first wall when the first protrusion is fit into the first receiving channel and the second protrusion is fit into the second receiving channel.

A linear luminaire includes a linear channel defining an interior space and a linear light inset configured for being inserted into the channel in the interior space. The light inset includes a cover and a printed circuit board fixed to the cover. The printed circuit board supports a plurality of light emitting diodes. The cover base wall includes a translucent portion. The light emitting diodes are arranged for emitting light through the translucent portion. The cover includes two cover connectors, each configured for being snapped into the channel to hold the cover in the interior space. The cover connectors are on an opposite side of the printed circuit board as the translucent portion.

A lighting assembly that includes a heatsink housing, a plurality of light emitting diode (LED) modules, and a power supply disposed within a power supply casing, wherein the power supply is for providing power to the LED modules. Each LED module includes a plurality of LEDs and is thermally connected to the heatsink housing. The power supply casing includes a structure for cooling the power supply.

A linear lighting assembly is disclosed which produces tailored light distributions valuable in many illumination applications. The linear lighting assembly comprises a unique light scattering optical element within a single edge lit linear lighting module housing configured to fit within a linear light fixture housing, both housings capable of being fabricated in a continuous extrusion process and cut to length as need for specific linear lighting assembly lengths. Light distributions attainable using the invention include, but are not limited to, symmetric and asymmetric bi-lobed “batwing” distributions for wide area direct and indirect lighting, and tilted or asymmetric distributions for perimeter lighting. It is also possible to achieve more rounded and symmetric distributions by an additional diffuser as a cover lens. The invention is particularly well-suited for linear lighting fixtures that are surface mounted, suspended or recessed. Various embodiments also provide means for adjusting light distributions dynamically to control light output characteristics by controlling the input signals to the LED board included in the assembly.

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.
