A downlight apparatus includes a fixing bar, a driver box, a light container and a light source. The fixing bar has two elastic units and a central part. The two elastic units are located at two opposite sides of the central part. The two elastic units are deformed so as to pass through a central hole of a fixing plate and then are released to attach to the fixing plate. The fixing plate is fixed to a platform. The driver box includes a driver for converting an external power to a driving current. The light container has a top cover and a lateral wall. The fixing bar is fixed on the top cover protruding toward the central hole of the fixing plate. A bottom side of the driver box is placed on the central part.

A mounting bracket for a lighting system includes a body portion having an elongated shape and defining a top side and a bottom side opposing the top side. The body portion defines, within the bottom side, a plurality of channels spaced apart along an axial direction of the elongated shape, wherein one or more channels of the plurality of channels is configured to receive a mounting portion of a linear light fixture of the lighting system. The body portion further defines, within the top side, a plurality of holes spaced apart along the axial direction corresponding to the plurality of channels, wherein one or more holes of the plurality of holes extends into a corresponding channel of the plurality of channels and is configured to receive a fastening structure therethrough.

A panel lamp includes a bottom case, a lamp cover, a lighting assembly arranged between the bottom case and the lamp cover, at least two bendable suspending assemblies arranged at two opposite sides of the bottom case. The bottom case defines a mounting groove, and an edge of the lamp cover is configured to be received into the mounting groove. The suspending assemblies are configured to hang the bottom case onto an overhead structure.

The assembly for a cartridge system with a hardwired electrical assembly comprising an adaptor as a separate unit in combination with a detachable quick-connect electrical cartridge, or in the form of two cartridges with male and female electrical connectors and snap-in attachments allowing for the connection of the two cartridges and the electrical connectors. The assembly may also have a retractable cord with a direct electrical connection such as a plug used to electrically connect the cartridge system to a fixture so as to allow the easy installation of a fixture in or on a structure. For example, a ceiling electrical box and mating cartridge may allow for a light fixture to be installed and mounted with no tools.

An adjustable light fixture includes a frame configured to rotatably connect to a support and rotate about a first axis. A lamp assembly is connected to the frame. The lamp assembly includes a housing defining a cavity. A light emitter is supported in the cavity. A lens is connected to the housing. A pivot assembly rotatably couples the lamp assembly to the frame about a second axis offset from the first axis.

A light emitting apparatus includes a light source, a unitary formed heat sink with a plurality of heat dissipating fins, a lensed enclosure that retains a light source and at least one power consuming device other than the light source. The lensed enclosure includes a recessed opening having at least a first wall that terminates at a substantially perpendicular second wall. The plurality of heat dissipating fins are disposed on at least one adjacent exterior side of the walled enclosure, the fins extending outwardly. At least one fin coupled to the heat sink extends beyond the light source, and the heat generated by the light source travels by conduction laterally through the heat sink to the at least one coupled fin.

A ceiling-mounted decontamination unit with one or more internal decontamination sources, which may be UV-C emitters, inside a housing with a hingable panel for access to the internal space of the housing for maintenance and repairs, and one or more fans inside the housing that re-circulate the air in a room and subject the air to the germicidal internal decontamination source inside the housing, decontaminating the air passing through the ceiling-mounted decontamination unit's internal space and destroying viruses, bacteria, and other pathogens. The ceiling-mounted decontamination unit draws the air in from the room or area where the ceiling-mounted unit is installed, subjects the air to the internal decontamination source destroying pathogens, and returns the decontaminated air back to the same room or area from which the air is drawn. An optional luminaire or external decontamination source may be attached to the room- or area-facing exterior of the ceiling-mounted decontamination unit.
