The receiving body includes a lamp cover and a cover body, the lamp cover is provided with an open end. The assembling stand is inserted into the lamp cover through the open end, and the assembling stand is used for assembling a power module and receiving a fan. The light source substrate is electrically connected to the power module. The light source substrate includes a plurality of end-surface LED substrates and a plurality of side-surface LED substrates. The plurality of end-surface LED substrates and the plurality of side-surface LED substrates are bent and enclosed to form a cylindrical light emitting body and clamp with the assembling stand. The lamp head mates with the cover body.

A luminaire assembly includes a frame and a back plate. In some examples, the frame includes a lip, and the back plate includes a tab. The back plate is positionable within a housing area of the frame such that the tab is engaged with the lip and the back plate is retained within the frame. In other examples, a luminaire assembly includes a wireless module with an antenna positioned adjacent to a module opening of the back plate. The antenna provides wireless transmissions above the top side of the back plate and below the bottom side of the back plate. A luminaire support clip for a luminaire assembly includes a base and a tab. The tab and the base define a receiving area, and the luminaire support clip receives a portion of an edge of a back plate of the luminaire assembly within the receiving area.

Disclosed is a luminaire including a ceiling mountable housing that defines an inner cartridge-receiving cavity accessible at an opening that is accessible in a healthcare space. A cartridge is provided to be received in the housing. The housing and the cartridge are configured to establish a first NSF-compliant sealing interface formed by at least one first barrier member extending along a first peripheral region between the housing and the cartridge to establish a first NSF-compliant pathogen barrier. The cartridge includes a light output region that is configured to locate an interior light guide and an exterior lens with an optical spacing therebetween. A second NSF-compliant sealing barrier interface is provided between the lens and the light guide formed by at least one second barrier member extending along a second peripheral region between the lens and light guide, and which is configured to establish a second NSF-compliant pathogen barrier therein.

The invention relates to a glazing having a first anchoring support being configured to engage with an electrical connector that is part of an electrically actuated device comprising at least one electrically actuated component and first and second electrical connectors that are connectable with an electrical power supply. Upon electrically connecting the first and second electrical connectors to the power supply, the electrically actuated component has electrical power supplied thereto and is in an energized state. When the first electrical connector is engaged with the first anchoring support, the electrical device is releasably fixed to the glazing. Connecting the power supply to the first anchoring support and the second electrical connector causes the electrically actuated component to switch from an unenergized state to the energized state. Mounting arrangements and vehicle lights to be mounted to a component of the structure of a vehicle are also described.

An LED plant illumination lamp module includes at least two light source modules and two lamp module cases located at both ends of the light source modules. Each of the light source modules includes a lamp tube, a circuit board mounted inside the lamp tube, and LED lamp beads fixed on the circuit board. At least two lamp tube insertion slots are arranged on one side of each of the lamp module cases, and two ends of the lamp tube are respectively inserted into the lamp tube insertion slots on the lamp module cases.
