Abstract
A fire-resistant, recessed lighting unit that obviates the need for a separate junction box and a separate incandescent “can”. Other embodiments are also described and claimed.
Claims26
A recessed lighting unit comprising:
- a casing having a closed top end, a side wall having a top edge that joins the closed top end, wherein the side wall extends downward from the closed top end so as to completely surround a cavity that is between the closed top end and an open bottom end of the casing that is defined by a bottom edge of the sidewall;
- a light source module having a plurality of driver wires that are to be electrically connected to a plurality of building electrical power wires, respectively, inside the cavity of the casing;
- a holding bracket disposed inside the cavity of the casing, the holding bracket comprising:
- a frame having a border that encloses a frame opening, the frame opening being shaped such that a housing of the light source module is insertable through the frame opening;
- and
- an arm having a proximal end coupled to the frame and a distal end positioned above the frame, the arm including a slot that runs along a length of the arm between the proximal end and the distal end;
- and
- an attaching member, disposed on the sidewall of the casing, that extends into the cavity of the casing and passes through the slot of the arm thereby substantially constraining the arm to the sidewall such that the arm is slidably adjustable along the slot relative to the attaching member.

A recessed lighting unit comprising:
- a casing having a side wall that surrounds a cavity and defines a bottom end opening;
- a holding bracket disposed inside the cavity, the holding bracket comprising:
- a frame having a frame opening;
- and
- an arm that extends upwards from the frame, the arm having a slot;
- and
- an attaching member positioned on the side wall of the casing, the attaching member extending into the cavity of the casing and passing through the slot of the arm to couple the arm to the side wall, wherein the holding bracket is slidable within the cavity along the slot of the arm.
4 more elements
A recessed lighting unit comprising:
- a casing having a sidewall that surrounds a cavity and defines an opening, the cavity having a cross section that is a polygon;
- a holding bracket, disposed inside the cavity, to couple a lighting module to the casing, the holding bracket including an arm with a slot;
- and
- an attaching member, coupled to the sidewall of the casing, that passes through the slot of the arm such that the holding bracket is slidably adjustable relative to the cavity along an axis defined by the slot.
