Solid state light assembly for flush mounted lighting fixtures
An assembly is provided herein for a lighting fixture and for retrofitting a flush mounted light fixture to be provided with solid state lighting.
1. A lighting fixture comprising:
a disc-shaped carrier including a carrier opening;
a lighting unit including a plurality of light generating elements and a driver configured to convert incoming alternating current power to direct current power for said plurality of light generating elements, said lighting unit defining a lighting unit opening with said light generating elements located about said lighting unit opening, wherein said lighting unit is fixed to said carrier with said carrier opening being aligned with said lighting unit opening, and, wherein said lighting unit has an outer perimeter which defines a diameter;
a barrier sized and shaped to limit contact with said lighting unit, said barrier including a central opening, wherein said barrier is sufficiently light transmissive to permit light generated by said lighting unit to pass therethrough; and,
a plurality of stand offs mountingly supporting said barrier relative to said lighting unit in a spaced-apart relationship with said central opening of said barrier aligned with said lighting unit opening and said carrier opening to define an open passageway for passage therethrough of mounting hardware for the lighting fixture, wherein said stand offs are fixed to said barrier and to said carrier with the lighting unit being located between said carrier and said barrier and said diameter of said lighting unit being less than spacing between each of said stand offs and a center of said open passageway.
2. The lighting fixture of claim 1 , wherein said barrier is made of glass.
3. The lighting fixture of claim 1 , wherein said barrier is made of a material which satisfies UL 94 5VA flammability rating.
4. The lighting fixture of claim 1 , wherein said carrier is metallic.
5. The lighting fixture of claim 1 , further comprising a thermal pad located between said lighting unit and said carrier.
6. The lighting fixture of claim 1 , further comprising a conductive barrier located between said lighting unit and said carrier, said conductive barrier configured to conduct heat from said lighting unit to said carrier.
7. The lighting fixture of claim 1 , wherein said barrier at least overlaps the light generating elements.
8. The lighting fixture of claim 7 , wherein, said barrier extends radially outwardly, away from said central opening, beyond said light generating elements to define a larger footprint than said lighting unit.
9. A retrofit assembly for flush mounted light fixtures, the assembly comprising:
a disc-shaped carrier including a carrier opening;
a lighting unit including a plurality of light generating elements and a driver configured to convert incoming alternating current power to direct current power for said plurality of light generating elements, said lighting unit defining a lighting unit opening with said light generating elements located about said opening, wherein said lighting unit is fixed to said carrier with said carrier opening being aligned with said lighting unit opening, and, wherein said lighting unit has an outer perimeter which defines a diameter;
a barrier sized and shaped to limit contact with said lighting unit, said barrier including a central opening, wherein said barrier is sufficiently light transmissive to permit light generated by said lighting unit to pass therethrough; and,
a plurality of stand offs mountingly supporting said barrier relative to said lighting unit in a spaced-apart relationship with said central opening of said barrier aligned with said lighting unit opening and said carrier opening to define an open passageway for passage therethrough of mounting hardware for the lighting fixture, wherein said stand offs are fixed to said barrier and to said carrier with the lighting unit being located between said carrier and said barrier and said diameter of said lighting unit being less than spacing between each of said stand offs and a center of said open passageway.
10. The lighting fixture of claim 9 , wherein said barrier is made of glass.
11. The lighting fixture of claim 9 , wherein said barrier is made of a material which satisfies UL 94 5VA flammability rating.
12. The lighting fixture of claim 9 , wherein said carrier is metallic.
13. The lighting fixture of claim 9 , further comprising a thermal pad located between said lighting unit and said carrier.
14. The lighting fixture of claim 9 , further comprising a conductive barrier located between said lighting unit and said carrier, said conductive barrier configured to conduct heat from said lighting unit to said carrier.
15. The lighting fixture of claim 9 , wherein said barrier at least overlaps the light generating elements.
16. The lighting fixture of claim 15 , wherein, said barrier extends radially outwardly, away from said central opening, beyond said light generating elements to define a larger footprint than said lighting unit.
