Sealed unibody-reflector luminaire
In a sealed recessed lighting fixture having a housing forming a ceiling-alignment plane and a light-emitting opening, at least one elongate lamp mounted to and within the housing and defining a fixture direction, at least one reflector surface parallel to the fixture direction, and a lens, the improvement wherein the at least one reflector surface is/are part(s) of a unibody-reflector assembly which includes: (a) two reflector sections terminating in longitudinal inner edges forming a gap therebetween; (b) a distal edge perimetrically along the light-emitting opening of the housing; (c) a seal between the distal edge and the housing at the opening; (d) two opposed substantially parallel endwalls each having a lens-engaging proximal edge; (e) the lens being an elongate shaped member terminating at opposite lens ends, the lens enveloping the at least one lamp and being of substantially constant cross-section along its length, whereby the unibody-reflector assembly is removable from the housing as a single unit to expose the lamp(s) in the housing for service.
1. In a sealed recessed lighting fixture having a housing forming a ceiling-alignment plane and a light-emitting opening, at least one elongate lamp mounted to and within the housing and defining a fixture direction, at least one reflector surface parallel to the fixture direction, and a lens, the improvement wherein the at least one reflector surface is/are part(s) of a unibody-reflector assembly which includes: (a) two reflector sections terminating in longitudinal inner edges forming a gap therebetween; (b) a distal edge perimetrically along the light-emitting opening of the housing; (c) a seal between the distal edge and the housing at the opening; (d) two opposed substantially parallel endwalls each having a lens-engaging proximal edge; (e) the lens being an elongate shaped member terminating at opposite lens ends, the lens enveloping the at least one lamp and being of substantially constant cross-section along its length, whereby the unibody-reflector assembly is removable from the housing as a single unit to expose the lamp(s) in the housing for service.
2. The recessed lighting fixture of claim 1 further including a pair of endcaps each engaged with a respective one of the endwalls, each lens end being in sealed engagement with a respective one of the endcaps.
3. The recessed lighting fixture of claim 2 wherein each lens end extends beyond a corresponding endwall.
4. The recessed lighting fixture of claim 1 wherein the proximal lens-engaging edges are complementary to the lens cross-section.
5. The recessed lighting fixture of claim 1 wherein the lens has an arcuate light-transmissive central portion facing the light-emitting opening and two longitudinal edge portions each in sealing engagement with a respective reflector section inner edge.
6. The recessed lighting fixture of claim 1 wherein the lens has an arcuate light-transmissive central portion facing the light-emitting opening, two inwardly-turned light-transmissive side portions therealong, and two longitudinal edge portions each in sealing engagement with a respective reflector section inner edge.
7. The recessed lighting fixture of claim 6 wherein the at least one lamp is a fluorescent tube substantially centered along the gap.
8. The recessed lighting fixture of claim 6 wherein the at least one lamp is a plurality of fluorescent tubes.
9. In a sealed recessed lighting fixture having a housing forming a ceiling-alignment plane and a light-emitting opening, at least one lamp mounted to and within the housing, at least one reflector surface of substantially constant cross-section along its length which defines a fixture direction, and a lens, the improvement wherein the at least one reflector surface is/are part(s) of a unibody-reflector assembly which includes: (a) two reflector sections terminating in longitudinal inner edges forming a gap therebetween; (b) a distal edge perimetrically along the light-emitting opening of the housing; (c) a seal between the distal edge and the housing at the opening; (d) two opposed substantially parallel endwalls each having a lens-engaging proximal edge; (e) the lens being an elongate shaped member terminating at opposite lens ends, the lens enveloping the at least one lamp and being of substantially constant cross-section along its length, whereby the unibody-reflector assembly is removable from the housing as a single unit to expose the lamp(s) in the housing for service.
10. The recessed lighting fixture of claim 9 further including a pair of endcaps each engaged with a respective one of the endwalls, each lens end being in sealed engagement with a respective one of the endcaps.
11. The recessed lighting fixture of claim 10 wherein each lens end extends beyond a corresponding endwall.
12. The recessed lighting fixture of claim 9 wherein the proximal lens-engaging edges are complementary to the lens cross-section.
13. The recessed lighting fixture of claim 9 wherein the lens has an arcuate light-transmissive central portion facing the light-emitting opening, two inwardly-turned light-transmissive side portions therealong, and two longitudinal edge portions each in sealing engagement with a respective reflector section inner edge.
14. The recessed lighting fixture of claim 9 wherein the at least one lamp comprises at least one LED module.
15. The recessed lighting fixture of claim 9 wherein the at least one lamp is an elongate lamp parallel to the fixture direction.
16. The recessed lighting fixture of claim 15 wherein the at least one lamp is a fluorescent tube.
17. The recessed lighting fixture of claim 15 wherein the at least one lamp is a plurality of fluorescent tubes.
