Abstract: A luminaire includes an adjustable torsion spring assembly for mounting the light engine assembly to a mounting frame and for providing the ability to conduct maintenance of the light engine assembly. The luminaire may include a mounting frame assembly; an light engine assembly engaged with at least a portion of the mounting frame assembly, the light engine assembly comprising at least one light source configured to emit light; and a support wire adjustably-coupled at a first end to a side of the light engine assembly, the support wire extending in the first direction from the side of the light engine assembly, and comprising at least one hook at a second end.

Abstract: A luminaire has a LED module, a block structure with a cavity, a plurality of fins extending from the block structure, and a slot extending through a sidewall of the block into the cavity. The LED module is slidably received on a mounting surface of the slot and configured to project light through an aperture of the cavity. The mounting surface has an area equal to or larger than that of the aperture.

Abstract: An aperture trim assembly for a recessed lighting fixture with an aperture trim that connects to a rotatable ring where the rotatable ring has a pair of tension springs attached. The tension springs connect the aperture trim assembly to a recessed lighting fixture, where the light may be rotated while the aperture trim remains fixed. The rotatable ring can rotate relative to the aperture trim allowing the aperture trim to remain fixed. A retention plate may further secure both a lens and the rotatable ring to the aperture trim.

Abstract: Aspects of this disclosure relate to a mounting frame assembly for use with coupling to an optical assembly, the mounting frame assembly may comprise: a mounting frame comprising a first attachment interface spaced apart from a second attachment interface, wherein the mounting frame is configured to support a junction box; an aperture plate, coupled to the mounting frame at the first and second attachment interfaces, the aperture plate comprising a first aperture configured to receive a reflector assembly; and a first mounting bracket adjustably-coupled to the first attachment interface, and a second mounting bracket adjustably-coupled to the second attachment interface, the first and second mounting brackets configured to provide adjustable coupling of the mounting frame to a ceiling structure between at least two positions along a vertical direction.

Abstract: A luminaire has a light engine configured to be attached to a light source circuit board or LED module. The light engine may have a block structure with a cavity extending into the block structure from an aperture. The light engine may also have a slot, extending through a sidewall of the block into the cavity perpendicular to a first direction. The slot may form a mounting surface that has a larger surface area than an area of the aperture, onto which the circuit board or LED module may be attached. Further, the circuit board or LED module may be removable from the cavity and slidable through the slot.

Abstract: An apparatus for retaining a trim to a lighting fixture utilizing a frame which is fixed relative to a surface at which the lighting fixture is mounted. The frame includes an opening and a surface surrounding the opening. One or more brackets are placed along the frame surface. A movable element of one bracket connects to the trim for support. Retaining of the trim is a accomplished by further fastening of the trim to another bracket placed along the surface surrounding the opening of the frame.

Abstract: A system for securing a light fixture to a grid of a suspended ceiling is described. The fixture has a cutout at each corner of its opposed sidewalls. The cutout is formed with vertically spaced, horizontal surfaces. A bracket has a plate with upwardly extending opposed legs disposed transverse to the plate. The legs are biased away from each other and are each provided with upwardy extending surfaces adapted to capture one of the horizontal surfaces of the cutout therebetween. The bottoms of the legs define feet adapted to sit on an associated grid member. The plate extends below the grid member so that the member is captured between the plate and the upwardly extending surfaces while flanges affixed to the legs engage the inside of the fixture to provide a positive engagement between the fixture and the grid.
