Fire rated recessed lighting fixture
A recessed lighting fixture includes a one-piece casing having i) a flat-crown-hat-shaped to be secured to a ceiling or the like and that is made of a fire-retardant material, ii) a flange fitting that is removably mounted to the one-piece casing therein, and iii) a light-emitting diode (LED) assembly mounted to the flange fitting therein.
1. A recessed lighting fixture comprising:
a one-piece casing made of a fire-retardant material; the one-piece casing including i) a peripheral wall having first and second longitudinal edges, ii) a top wall that closes the peripheral wall at the first longitudinal edge thereof and iii) a peripheral flange extending outwardly from the peripheral wall near the second longitudinal edge thereof;
at least two spring clips that are operatively secured to the one-piece casing;
a flange fitting assembly that includes i) a ring portion having first and second longitudinal edges and being configured to be snugly mounted to the one-piece casing therein at the second longitudinal edge of the peripheral wall thereof, and ii) an outer flange portion that extends outwardly from the ring portion near the second longitudinal edge thereof and generally perpendicularly therefrom; and
a light-emitting diode (LED) assembly operatively mounted to one of the one-piece casing and flange fitting.
2. A recessed lighting fixture as recited in claim 1 , wherein the one-piece casing having a flat-crown-hat-shaped.
3. A recessed lighting fixture as recited in claim 1 , further comprising at least one lens secured to the flange fitting therein.
4. A recessed lighting fixture as recited in claim 3 , wherein the flange fitting including an inner flange that extends inwardly from the ring portion near the second longitudinal edge thereof; the inner flange defining a housing for the at least one lens.
5. A recessed lighting fixture as recited in claim 1 , wherein the top wall of the one-piece casing having an embossed portion defining a lodging on a side of the top wall opposite the peripheral flange.
6. A recessed lighting fixture as recited in claim 5 , further comprising a cap made of a fire-retardant material that is removably secured to the top wall for closing the lodging.
7. A recessed lighting fixture as recited in claim 6 , wherein the cap including an embossed portion which defines with the top wall a channel that allows passage for connectors.
8. A recessed lighting fixture as recited in claim 5 , wherein the lodging is provided with a connector-receiving hole therein to allow passage for connectors from the LED assembly.
9. A recessed lighting fixture as recited in claim 1 , further comprising a convex cap made of a fire-retardant material that is removably secured to the top wall for defining a lodging therewith.
10. A recessed lighting fixture as recited in claim 1 , wherein the flange fitting including an annular groove between the ring portion and outer flange portion for complementary receiving the peripheral flange of the one-piece casing.
11. A recessed lighting fixture as recited in claim 1 , wherein the LED assembly includes at least one of a flexible LED strip and a solid printed circuit board (PCB).
12. A recessed lighting fixture as recited in claim 1 , wherein the fire-retardant material is cold rolled steel (SPCC) or a ceramic.
