Abstract

A lighting arrangement can include a mounting ring, a luminaire, locking arms, and posts. The mounting ring can extend along a central longitudinal axis. The luminaire can have a housing assembly and a light emitter. The locking arms can each include a circumferential portion extending about the central longitudinal axis. The circumferential portions can each extend from a first end to a second end distal relative to the first end and each can have an upper face and a lower face. The mounting ring and the luminaire can be interconnected by moving the posts past the second ends along the central longitudinal axis, rotating the mounting ring and the luminaire relative to one another about the central longitudinal axis to slide the posts along one of the upper and lower faces.

A lighting arrangement comprising:

a mounting ring extending along a central longitudinal axis and having a plurality of mounting apertures and a circular wall, said circular wall having an inwardly-facing surface encircling said central longitudinal axis and defining a radial boundary of a cavity, said circular wall also having an outwardly-facing surface opposite to said inwardly-facing surface with a thickness of said circular wall defined between said inwardly-facing surface and said outwardly-facing surface, said circular wall extending a height along said central longitudinal axis between a downwardly-facing surface and an upwardly-facing surface;
a luminaire having a housing assembly and a light emitter, said housing assembly at least partially enclosing said light emitter, said housing assembly at least partially received in said cavity;
a plurality of locking arms each fixedly associated with one of said circular wall and said housing assembly, each of said plurality of locking arms including an axial portion extending along said central longitudinal axis and a circumferential portion extending about said central longitudinal axis, each of said circumferential portions extending from a first end at an intersection with one of said axial portions to a respective second end distal relative to said first end, and each of said circumferential portions having an upper face directed in the same direction as said upwardly-facing surface and a lower face directed in the same direction as said downwardly-facing surface;
a plurality of posts each fixedly associated with the other of said circular wall and said housing assembly, each of said plurality of posts extending away from said other of said circular wall and said housing assembly along a respective post axis that intersects said central longitudinal axis, a width of each post defined in a direction about said central longitudinal axis;
wherein said mounting ring and said luminaire are interconnected by moving each of said plurality posts past each of said plurality of second ends along said central longitudinal axis and then rotating said mounting ring and said luminaire relative to one another in a first angular direction about said central longitudinal axis and sliding each of said plurality of posts along one of said upper and lower faces such that said one of said upper and lower faces thereby defines a sliding surface;
wherein said sliding surface includes a first area that is substantially flat in side profile and extends a first arcuate length about said central longitudinal axis, a second area that is substantially flat in side profile and extends a second arcuate length about said central longitudinal axis, and at least one protuberance creating a gap between said first area and said second area and extending a third arcuate length about said central longitudinal axis;
wherein, for at least one of said plurality of posts and said respective sliding surface, said at least one of said plurality of posts is configured to slide over said first area and said at least one protuberance and said second area of said respective sliding surface;
and
wherein said third arcuate length is less than both of said first arcuate length and said second arcuate length.
