Abstract
A recessed light fixture includes a trim housing having a trim housing wall and a trim housing cavity bound by the trim housing wall. The recessed light fixture further includes a trim having a trim wall and a trim cavity bound by the trim wall, where the trim is at least partially positioned in the trim housing cavity. The recessed light fixture also includes a trim retention elastic band positioned around the trim wall and between the trim wall and the trim housing wall. The trim retention elastic band is compressed by the trim wall and the trim housing wall such that the trim is attached to the trim housing by friction between the trim retention elastic band and the trim wall and between trim retention elastic band and the trim housing wall.
Claims15
A recessed light fixture, comprising:
- a trim housing having a trim housing wall and a trim housing cavity bound by the trim housing wall, wherein the trim housing includes a channel formed at least in part by the trim housing, wherein the channel has a top wall;
- a trim having a trim wall, wherein the trim includes a trim flange that extends outwardly from the trim wall, wherein the trim is at least partially positioned in the trim housing cavity;
- a trim retention elastic band stretched around the trim wall and positioned in the trim housing cavity above the top wall of the channel during installation of the elastic band and at least part of the trim into the trim housing cavity, wherein the trim retention elastic band has an unstretched inner diameter (Dri) that is smaller than an outer diameter (Dt) of the trim, and wherein the trim retention elastic band is compressed by the trim wall and the trim housing wall such that the trim is attached to the trim housing by friction between the trim retention elastic band and the trim wall and between trim retention elastic band and the trim housing wall;
- and
- wherein the top wall of the channel limits an upward movement of the trim during installation of the trim into the trim housing cavity by preventing further movement of the trim flange into the trim housing once the trim flange comes in contact with the top wall.

- wherein the top wall of the channel limits an upward movement of the trim during installation of the trim into the trim housing cavity by preventing further movement of the trim flange into the trim housing once the trim flange comes in contact with the top wall;
- a lens attached to the trim, wherein the trim has a trim cavity, and wherein the lens closes off a top opening of the trim and prevents air flow through the trim cavity;
- and
- a rotatable enclosure section, wherein a light source is attached to the rotatable enclosure section and is configured to emit a light toward the lens and the trim cavity.
