The present disclosure relates generally to light fixtures and to lighting assembly attachment systems. The present disclosure provides a lighting fixture extending no more than 3 inches from the building surface. A light source is disposed in a housing thereof and is configured to emit light through the open side of the housing so as to direct the light in an upward direction. The disclosure also provides lighting assembly including a housing having a base and a cavity below the base, a light source disposed in the cavity of the housing, and one or more clips configured to attach to a flange of a ceiling support beam. Each clip includes an upper arm, a lower arm, and a retainer disposed on the lower arm configured to engage the base of the housing such that the housing is held up by the one or more clips.

A retention structure for retaining a recessed lighting fixture behind a ceiling includes an attachment structure that has a first wall and a second wall. The attachment structure is designed to be attached to a housing of a recessed light fixture. The retention structure further includes a screw attached to the first wall of the attachment structure and to the second wall of the attachment structure. The retention structure also includes a pawl attached to the threaded screw. The pawl is rotatable along with the threaded screw. The pawl is also axially movable along the threaded screw between the first wall of the attachment structure and the second wall of the attachment structure.

An LED downlight assembly accommodates square and round trims and its components may be removed irrespective of the presence of mudded in round or square mud plates. The assembly also comprises a collar that can be fitted to ceiling of varying thicknesses.

Provided is an adaptable fire-resistant housing for a light fixture, comprising: a. a junction box made from steel, the junction box having an opening on a bottom configured to receive the light fixture; and b. an adjustable ring attached to the bottom of the housing, the adjustable ring having an opening configured to be attached to the light fixture or an adapter ring; wherein the light fixture or the adapter ring is attached to the adjustable ring.

A light module includes a heat sink and one or more light sources coupled within a heat sink cavity formed therein. The heat sink includes an internal surface surrounding the cavity. The internal surface includes a mounting region, a reflector region extending from the perimeter of the mounting region to a distal end, and a decorative region extending from the distal end to a second distal end. The light module includes multiple mounting pads coupled circumferentially around a portion of the heat sink. The mounting pads are configured to facilitate the heat sink being coupled within different housing diameter sizes. The light module includes a trim ring integrally formed with the heat sink and extending radially outward from one end of the heat sink.

A recessed downlight fixture and method for installation is provided. The recessed downlight fixture can be installed in a retrofit application, after a ceiling is installed, through a pre-existing opening in that ceiling. Alternatively, a recessed downlight fixture according to a second embodiment can be installed before a ceiling is present. In either embodiment, the light source coupled to, for example, a heat sink, can be universally moved in three degrees of movement, rotationally, along a tilt axis, or further within the ceiling to increase or decrease the recess. All such universal adjustments can take place through and below the ceiling opening during or after installation.

A lighting structure includes a junction box that has a cavity, and a mounting plate that has an inner section and a perimeter section. The junction box is attached to the mounting plate, and the mounting plate has a wire opening therethrough for routing an electrical wire from the junction box to a light source. The perimeter section of the mounting place is outside the junction box.

The present disclosure provides an assembly and disassembly device for ceiling equipment. The device includes an inner frame, an outer frame, a leg, a pull rod, a transmission rod, a cover plate and an elastic sheet, wherein the outer frame is disc shaped and has the inner frame disposed therein, the outer frame has four legs disposed equally spaced at the periphery thereof, furthermore, the inner frame has the cover plate mounted therein, the cover plate has the transmission rod disposed thereon, and the transmission rod is connected to the pull rod, wherein the inner frame can be rotated so that the cover plate is driven to rotate, as a result the transmission rod drives the pull rod and the pull rod drives the leg to be clamped on a support plate mounted on a wall surface preset with a mounting hole.

A downlight retrofit assembly includes a reflector, the reflector defining a top reflector end and a bottom reflector end, the reflector defining a reflector bore extending through the reflector from the top reflector end to the bottom reflector end, the reflector bore defining a top reflector aperture and a bottom reflector aperture; a lens, the lens attached to the reflector proximate the bottom reflector end, the lens covering the bottom reflector aperture; and a light engine, the light engine comprising a SSL source and PCB, the SSL source attached to the PCB, the light engine covering the top reflector aperture, the SSL source disposed within the top reflector aperture, the SSL source configured to emit light through the lens.

A retrofit trim lighting device is provided. In example embodiments, the retrofit trim lighting device comprises a bracket comprising an opening; at least one torsion spring secured to the bracket and configured to mount the retrofit trim lighting device within a recessed housing; a retrofit housing comprising at least one light engine; and an engagement element. The engagement element is secured to the retrofit housing through the opening of the bracket such that, when so secured, the retrofit housing and the bracket are rotatable relative to one another.
