Patent Images
1. A recessed lighting fixture comprising:
- an outer casing for housing a) a light source module for emitting light and b) a driver for powering the light source module to emit light, wherein the outer casing has a base end joined to one end of a side wall, and an inner surface of the base end and an inner surface of the side wall define a cavity, and wherein the side wall of the outer casing has another end that defines an opening of the cavity;
a trim for covering an opening in a ceiling or a wall behind which the outer casing is installed;
a mounting mechanism to couple the side wall of the outer casing to a hangar bar whose length is adjustable along a first direction, wherein the mounting mechanism allows a position of the outer casing to be adjusted relative to the hangar bar in a second direction substantially perpendicular to the first direction;
a ring having a flat portion and attached to the side wall of the outer casing, the ring having a plurality of holes formed in the flat portion thereof, each hole of the plurality of holes to receive a corresponding fastener for securing a unified casting to the ring, the unified casting housing the driver and the light source module together with a reflector and a lens as a single unit; and
a plurality of wire connectors within the outer casing to join a first plurality of wires, which carry electrical power with at least one of 120 VAC or 277 VAC and that extend into the casing to deliver the electrical power from a circuit breaker or wall switch, to a second plurality of wires extending out of the driver,wherein the outer casing serves as both a junction box to house the plurality of wire connectors and a luminaire enclosure,wherein the trim has a) a trim base with an outer surface and b) a flange extending outwardly from the outer surface of the trim base, andwherein when the trim base is positioned inside the cavity of the outer casing the flange lies against a front face of the ceiling or wall behind which the outer casing is installed.

Abstract
The recessed lighting fixture includes a light source module and a driver housed within a unified casting, and within a shared outer casing. The outer casing may be coupled to a hangar holder that is movably coupled to a corresponding hangar bar. The outer casing, including the light source module and driver installed therein, may move both 1) in the length direction of the hangar bar and 2) perpendicular to the length direction of the hangar bar. The recessed lighting fixture may have less bulk and size than traditional recessed lighting fixtures. Other embodiments are also described and claimed.
