Recessed lighting systems
First Claim
1. A recessed light system, comprising:
- a compact lighting assembly, comprising;
a light source module including at least one LED;
electrical wires to receive AC voltage from an electrical system of a buiding;
an AC to DC converter to receive electrical energy from the electrical wires and supply regulated electrical energy to power the light source module;
a lens;
a reflector; and
a heat-sinking housing having a rear portion above which a cavity is formed, a front position that surrounds a aperture, and a sidewall, wherein;
a first end of the sidewall is joined to the rear portion and a second end of the sidewall is joined to the front portion;
the sidewall extends around the central axis of the heat-sinking housing;
the rear portion and the sidewall are formed of a heat conductive material capable of dissipating heat generated by the light source module away from the light source module;
the heat-sinking housing further comprises a twist-and-lock mechanism comprising flanges that extend outward from the front portion of the heat-sinking housing, wherein a maximum ouside width of the flanges is greater than 3 ½
inches;
the distance along the sidewall, between the flanges and an outside surface of the rear portion, is less than 1 ½
inches;
a maximum width of the sidewall, between the flanges and the rear portion, is less than 3 ½
inches; and
the light source module is positioned inside the cavity closer to an inside surface of the rear portion than to an exterior surface of the front portion of the heat-sinking housing;
wherein;
at least a portion of a front surface of the lens is coplanar with the exterior surface of the front portion of the heat-sinking housing to direct light produced by the light source module through the aperture into an area surrounding the recessed lighting system;
the reflector is positioned inside the heat-sinking housing to direct light emitted from the light source module through the lens;
the electrical wires pass through the rear portion of the heat-sinking casting; and
the AC to DC converter is positioned between the rear portion of the heat-sinking housing and the reflector.

Abstract
A recessed lighting system includes a casting, a light source module and one or more optic elements disposed in the casting, and a driver to power the light source module. In one example, the system also includes a junction box or a 4-10 inch recessed lighting fixture enclosure in which the casting is disposed. The system may also include a trim to cover an exposed edge of a hole in a ceiling or a wall into which the recessed lighting system is installed. The system also may include one or more connecting mechanisms to couple the trim to one or both of the junction box/enclosure and the casting. In one example, the casting includes a front end face and the one or more connecting mechanisms couple the trim to the front end face of the casting. The connecting mechanism(s) may include a twist-and-lock friction connection.
