Lighting assembly
View Patent ↗A lighting assembly is provided. The lighting assembly includes a bracket and a frusto-spherical housing received by the bracket and mounted for rotation relative to the bracket. By rotating the frusto-spherical housing within the bracket, light emitted by the lighting assembly can be focused or directed in a selected direction.
1. A lighting assembly comprising:
a bracket that defines a cavity;
a frusto-spherical housing received within the cavity of said bracket, said frusto-spherical housing mounted for rotation relative to said bracket, said frusto-spherical housing defining a chamber and an opening that permits access to the chamber of said frusto-spherical housing, said frusto-spherical housing having an outer surface,the outer surface of said frusto-spherical housing and said bracket defining a plurality of passages that facilitate a flow of air therethrough;
a light source mounted within the chamber of said housing and directed towards the opening of said housing; and
an adjustment mechanism mounted to said housing at the opening of said housing, said adjustment mechanism extending away from said housing.
2. The lighting assembly of claim 1 , further comprising a cover mounted at the opening of said housing, said cover comprising a transparent or translucent material.
3. The lighting assembly of claim 2 , wherein said adjustment mechanism is mounted to said cover.
4. The lighting assembly of claim 2 , wherein said cover further comprises a lens.
5. The lighting assembly of claim 4 , wherein a distance between said lens and said light source is selectively adjustable in order to focus light emitted from said light source.
6. The lighting assembly of claim 1 , further comprising a conical reflector mounted within the chamber of said frusto-spherical housing adjacent said light source.
7. The lighting assembly of claim 1 , wherein said frusto-spherical housing comprises a plurality of fins that extend outwardly from said frusto-spherical housing.
8. The lighting assembly of claim 7 , wherein each fin of the plurality of fins has a distal portion that is positioned immediately adjacent said bracket.
9. The lighting assembly of claim 1 , wherein said light source comprises a light emitting diode.
10. The lighting assembly of claim 1 , wherein said adjustment mechanism comprises a stem that extends away from said frusto-spherical housing to a distal end, and a handle mounted on the distal end of the stem.
11. The lighting assembly of claim 10 , wherein the handle of said adjustment mechanism comprises a material with a heat capacity less than about sixteen hundred joules per kilogram-degree kelvin and a thermal conductivity less than about two-hundred and twenty milliwatts per meter-degree kelvin.
12. The lighting assembly of claim 1 , wherein said frusto-spherical housing comprises a die cast material.
13. The lighting assembly of claim 12 , wherein the die cast material comprises aluminum or an aluminum-zinc alloy.
14. An appliance comprising:
a casing; and
a lighting assembly comprising:
a mounting plate secured to said casing, said mounting plate defining an aperture;
a bracket mounted to said mounting plate at the aperture of said mounting plate;
a frusto-spherical housing rotatably received within the aperture of said mounting plate and secured to said mounting plate with said bracket, said frusto-spherical housing defining a chamber and an opening that permits access to the chamber of said frusto-spherical housing, said frusto-spherical housing having an outer surface, the outer surface of said frusto-spherical housing and said bracket defining a plurality of passages that facilitate a flow of air therethrough;
a light source mounted within the chamber of said housing and directed towards the opening of said housing; and
an adjustment mechanism mounted to said housing at the opening of said housing, said adjustment mechanism extending away from said housing.
15. The appliance of claim 14 , further comprising a cover mounted at the opening of said housing, said cover comprising a transparent or translucent material.
16. The appliance of claim 14 , wherein said frusto-spherical housing comprises a plurality of fins that extend outwardly from said frusto-spherical housing.
17. The appliance of claim 14 , wherein said light source comprises a light emitting diode.
18. The appliance of claim 14 , wherein said adjustment mechanism comprises a stem that extends away from said frusto-spherical housing to a distal end, and a handle mounted on the distal end of the stem.
