A housing assembly for a recessed lighting system includes a housing with integrally formed cable routing features, mounting features, and alignment features. The integration of multiple features into the housing is enabled by forming the housing from a polymer using an injection molding process instead of sheet metal. For a new construction installation, the housing includes integrally formed bar hanger holders to support and guide bar hangers for installation onto two or more support structures, nail-in features for installation onto a single support structure, and one or more alignment features to position the housing against the single support structure when the nail-in features are used for installation. For a remodel installation, the housing includes a flange to abut a bottom surface of a ceiling and one or more spring clips mounted to the housing to abut a top surface of the ceiling.

A lighting fixture is provided that may include a channel configured for disposition at least partially within a recessed groove. The channel may be configured for mounting in the recessed groove by one or more fasteners, brackets and/or a combination of both fasteners and brackets. The lighting fixture may further include a mounting tray positioned within the channel and configured for mounting of a lighting element. The lighting fixture may also include a lens, for example a flexible lens, disposed at least partially within the channel and configured to at least partially cover the lighting element.

A plaster frame for a luminaire includes a first attachment tab on a side of the plaster frame and a second attachment tab on the side of the plaster frame. The plaster frame further includes a back wall. The first attachment tab and the second attachment tab each include a rib protruding toward the back wall. The back wall and the first attachment tab define a first space for a hanger bar assembly to extend therethrough, and the back wall and the second attachment tab define a second space for the hanger bar assembly to extend therethrough.

A hanger bar assembly includes a first hanger bar member and a first attachment head coupled to the first hanger bar member by a first coupling segment that is horizontally offset from the first hanger bar member. The hanger bar assembly further includes a second hanger bar member and a second attachment head coupled to the second hanger bar member by a second coupling segment. The first hanger bar member and the second hanger bar member are designed to interlock with each other. An end portion of the first hanger bar member is designed to extend past the second attachment head, and an end portion of the second hanger bar member is designed to extend past the first attachment head through a gap that is between the first hanger bar member and first attachment head.

A lighting device assembly includes a light engine assembly and a mounting housing. A rotatable support structure supports the light engine assembly on the mounting housing for rotation relative to the mounting housing about a first axis. A releasable connection mechanism locks the light engine assembly to the rotatable support structure and is selectively releasable to release the light engine assembly from the rotary support structure.

A luminaire for installing in a grid ceiling includes at least one catch which is arranged in such a way on the luminaire and designed such that the at least one catch snaps into place automatically behind a portion of an element of the grid ceiling and thus engages behind the portion of the element of the grid ceiling in order to hold the luminaire on the grid ceiling. In addition, an assembly for a grid ceiling includes at least one ceiling profile element and at least one such luminaire.

A linear light fixture assembly for supporting a light fixture in a ceiling structure, comprises a light fixture mounting structure having a pair of opposed boundary regions configured to fit within a designated light fixture receiving region in the ceiling structure, and a plurality of spring elements configured to spaced outwardly from at least one of the boundary regions, each spring element having a mounting region configured to be anchored to the mounting structure and a free end region to extend therefrom and to be laterally outwardly biased in a first position to form a path of contact with a support surface region on the ceiling structure to anchor the structure in the receiving region, each of the spring elements configured to be movable toward the corresponding boundary region in a second position to release the path of contact to release the light fixture from the receiving region.

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.

The present invention relates to brackets for fixing a lamp to be embedded in the ceiling of a building to an M bar inside the ceiling and, more specifically, to brackets having a plurality of hook bars (100) hung on an M bar of the ceiling such that the brackets are loosely hung on the M bar in one step and then, a lamp is brought into close contact with the ceiling by only pressing control buttons (300) without tightening a screw. Brackets for an embedded lamp, according to the present invention, comprises a plurality of brackets on the edge of the lamp. A body of each bracket comprises a spring fixing shaft (100-4), two vertical movement guides, and one horizontal movement guide. In particular, a hook bar and a control button (300) are seated on a guide which forms a vertical movement path, and a control bar (200) and a control bar spring (200-2) are seated on a horizontal guide which forms a horizontal movement path. Thereafter, when the hook bar (100) pushed downward by a hook spring (100-3) is pulled upward, the control bar (200) is pushed to the left by means of the elasticity of the control bar spring (200-2) and thus blocks the back of the hook bar (100) such that a gap between a hook head. (100-1) and the bracket body is fixed in a widened state. When the hook head (100-1) is hung on the M bar in this state, the lamp is loosely mounted on the M bar. When pushing the edge of the lamp upward, the control button (300) is pressed against the N bar and pushes the control bar (200) to the right, and thereafter, as the hook head (100-1) is pulled by means of the elasticity of the hook spring (100-3), the lamp is brought into close contact with the ceiling.
