Light fixture mounting method and assembly
An assembly for mounting a light fixture in a hole in a ceiling panel and including an annular trim ring that's held upward against a lower surface of a ceiling panel by the light fixture to be mounted, such that the trim ring spans an annular gap between such light fixture and the ceiling panel hole. A top plate is carried by the ceiling panel across the ceiling panel hole and includes a top plate hole that receives the light fixture to be mounted such that the top plate spans an annular gap between the light fixture and the ceiling panel hole. A mount supports the light fixture on the top plate in a position holding the trim ring up against the lower surface of the ceiling panel.
1. A method for mounting a light fixture in a hole in a ceiling panel, the method including the steps of:
providing a light fixture comprising a lamp housing and a circumferential flange extending radially outward from around the lamp housing;
providing a ceiling panel having a ceiling panel hole larger in circumference or diameter than the fixture;
providing a light fixture mounting assembly comprising an annular trim ring having an outer diameter larger than a diameter of the ceiling panel hole and larger than an outer diameter of the circumferential flange and having a trim ring hole smaller than the ceiling panel hole diameter but large enough to receive the light fixture, the assembly further comprising a top plate large enough to span the ceiling panel hole and having a top plate hole large enough to receive the light fixture;
supporting the top plate on the ceiling panel in a position spanning the ceiling panel hole and with the top plate hole being disposed over the ceiling panel hole in a position to receive the light fixture;
supporting the trim ring on the circumferential flange of the light fixture;
passing the light fixture upward through the ceiling panel hole and the top plate hole; and
supporting the light fixture on the top plate in a position holding the trim ring up against a lower surface of the ceiling panel in a position spanning a circumferential gap formed between an inner circumference of the ceiling panel hole and an outer circumference of the circumferential flange of the light fixture.
2. The method of claim 1 in which:
the light fixture mounting assembly is provided including a mount; and
the step of supporting the light fixture on the top plate includes using the mount to support the light fixture in a position on the top plate in which the light fixture is holding the trim ring up against the lower surface of the ceiling panel.
3. The method of claim 2 in which:
the mount includes at least two projections; and
the step of using the mount includes strapping the at least two projections to the light fixture in positions where at least a portion of the at least two projections rests on the top plate.
4. The method of claim 2 in which the mount includes a spring clip configured and positioned to engage and support the light fixture on the top plate once the light fixture reaches its position holding the trim ring up against a lower surface of the ceiling panel.
5. The method of claim 2 in which:
the mount includes:
an interiorly-threaded ring carried by the top plate in a position coaxially aligned with the top plate hole; and
an exterior thread disposed around the light fixture; and
the step of supporting the light fixture on the top plate includes rotating the light fixture into threaded engagement with the interiorly-threaded ring.
