Abstract: A downlight lighting assembly comprising a plurality of notches and engaging members to ease the alignment and assembly of the components. The downlight lighting assembly comprises an LED chip removably connected to a heatsink with a mixing chamber secured to the heatsink, where securing the mixing chamber to the heatsink provides the compressive force for an LED connector to engage and provide the electrical connection to the LED chip. The heatsink also has a plurality of protrusions on its upper edge to engage a lower wall of a reflector to secure the reflector to the lighting assembly.

Abstract: An adjustable assembly for an adjustable downlight fixture assembly with a heatsink comprising a plurality of cooling fins that is connected to a mounting bracket where the heatsink is tiltably engaged with the mounting bracket. The heatsink is configured to receive a light source and may tilt within a confined space of the downlight fixture assembly up to 45 degrees from a vertical plane. The mounting bracket comprises a first side wall and a second side wall with a front wall connected between them where the first side wall and second side wall are connected to a rotation ring that is rotatably engaged with the frame of the downlight fixture.

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: 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: In an embodiment, a diffuser assembly for a multiple-LED lighting lamp is provided. The diffuser assembly is configured to be attached to multiple-LED lighting lamp with a center cavity and an integral fan that draws air from the lighting lamp to cool the LEDs. The diffuser assembly may comprise a diffuser plate and a diffuser bushing. The diffuser plate may be generally circular in shape and may include a diffuser portion and a circular hole located in the center of the diffuser portion. The diffuser bushing may be configured to be inserted through the circular hole and into the center cavity of the multiple-LED lighting lamp.
