A twist-and-lock mounting bracket may secure a lighting fixture to a mounting surface. The twist-and-lock mounting bracket may define an aperture having features corresponding to the shape of a twist-and-lock element disposed on a housing of a lighting fixture. Accordingly, the twist-and-lock element may be configured to extend through the aperture while the corresponding features of the twist-and-lock element and the aperture are aligned. The housing may then be rotated such that the tabs do not align with the corresponding features of the aperture, and the twist-and-lock element is thereby prevented from sliding through the aperture. The mounting bracket may be secured to a junction box positioned within a mounting surface, or it may be secured to a biasing bracket having one or more second resilient members configured to engage the interior of a recessed can light, such that the lighting fixture may be secured to the recessed can light.

Screw ramp joiner bracket and system for adjoining light fixture sections

An example joiner system for joining a first section and a second section of a fixture includes a joiner bracket that has formed therein a depressed ramp region. A joiner fastener, such as a screw, may engage against the angled walls of the joiner bracket ramp, to translate the vertical movement of the screw into a horizontal, longitudinal movement of the joiner bracket. The joiner bracket may be rigidly coupled to one section of a light fixture assembly, such that engaging the screw ramp with a fastener that extends through another section of the light fixture causes the two fixture sections to move toward each other. As vertical movement of a fastener produces horizontal movement of the joiner bracket, the joiner fastener or set screw may extend outside of the light fixture assembly, so as to be readily accessible by a technician.

DUAL REDUNDANCY HIGH RELIABILITY LED LIGHTING PLATFORM
20230243495 · 2023-08-03 · ·

An elongated lighting module having an asymmetric illumination source formed from at least two rows of light emitting diodes (LEDs) that extend along the long axis of the module and are independently controllable. The lighting modules are powered via a wiring harness that extends down a support pole to a power converter stack having LED drivers to control the modules. The power supply for lighting module includes a power enclosure having individual light emitting drivers for powering the rows of light emitting diodes that can adjust the power level to compensate for the loss of power from another of the light emitting drivers. The power supply may also include a backup that can be switched over to power the rows of light emitting diodes in the event of a failure.
