Replaceable baffles for light fixtures
A light fixture can include a housing having at least one housing wall having an inner surface that forms a cavity, where the inner surface of the at least one housing wall has at least one baffle coupling feature disposed thereon. The light fixture can also include a baffle removably coupled to the housing, where the baffle includes at least one baffle wall having an outer surface, where the outer surface of the at least one baffle wall has at least one housing coupling feature disposed thereon. The baffle can be coupled to the housing and decoupled from the housing without use of tools.
1. A light fixture comprising:
a housing comprising at least one housing wall having an inner surface that forms a cavity, wherein the inner surface of the at least one housing wall has at least one baffle coupling feature disposed thereon; and
a baffle removably coupled to the housing, wherein the baffle comprises at least one baffle wall having an outer surface, wherein the outer surface of the at least one baffle wall has at least one housing coupling feature disposed thereon,
wherein the at least one baffle coupling feature and the at least one housing coupling feature become coupled to each other by rotating the baffle in a first direction relative to the housing, and
wherein the at least one baffle coupling feature and the at least one housing coupling feature become decoupled from each other by rotating the baffle in a second direction opposite the first direction relative to the housing.
2. The light fixture of claim 1 , wherein the inner surface of the at least one housing wall, when viewed from below, is conical, and wherein the outer surface of the at least one baffle wall, when viewed from above, is conical.
3. The light fixture of claim 1 , wherein the at least one housing coupling feature comprises at least two tabs that extend from the outer surface of the at least one baffle wall, and wherein the at least one baffle coupling feature comprises at least two slots disposed in the inner surface of the at least one enclosure wall.
4. The light fixture of claim 1 , wherein the at least one housing coupling feature comprises a first housing coupling feature and a second housing coupling feature, wherein the first housing coupling feature and the second housing coupling feature are offset relative to each other around the baffle.
5. The light fixture of claim 1 , wherein the first at least one baffle coupling feature has a spiral shape.
6. The light fixture of claim 1 , wherein the baffle is rotated less than a half turn relative to the housing to couple the at least one baffle coupling feature and the at least one housing coupling feature to each other.
7. The light fixture of claim 1 , wherein the first at least one baffle coupling feature comprises at least one slot, wherein the at least one slot comprises an opening and a detent disposed opposite the opening.
8. The light fixture of claim 1 , wherein a distal edge of the baffle is substantially flush with a trim that extends from a distal end of the at least one housing wall when the baffle is coupled to the housing.
9. The light fixture of claim 8 , wherein the distal end of the at least one housing wall comprises a recess for receiving the baffle when the baffle is coupled to the housing.
10. A baffle for a light fixture, the baffle comprising:
at least one wall having an inner baffle surface and an outer baffle surface, wherein the inner baffle surface is configured to control effects of light emitted by the light fixture; and
at least one housing coupling feature disposed on the outer baffle surface of the at least one wall,
wherein the at least one housing coupling feature is configured to detachably couple to at least one baffle coupling feature disposed on an inner housing surface of a housing of the light fixture,
wherein the at least one housing coupling feature is configured to become coupled to the at least one baffle coupling feature by rotating the baffle in a first direction relative to the housing,
wherein the at least one housing coupling feature is further configured to become decoupled from the at least one baffle coupling feature by rotating the baffle in a second direction that opposes the first direction relative to the housing.
11. The baffle of claim 10 , wherein the at least one housing coupling feature comprises at least two tabs that extend from the outer surface of the at least one wall.
12. The baffle of claim 11 , wherein the first tab and the second tab are not spaced equidistantly from each other around the outer baffle surface.
13. The baffle of claim 11 , wherein the first tab and the second tab are spaced equidistantly from each other around the outer baffle surface.
14. The baffle of claim 10 , further comprising:
an alignment feature disposed on the at least one wall, wherein the alignment feature is configured to properly align the at least one housing coupling feature relative to the at least one baffle coupling feature when the at least one housing coupling feature is about to couple to the at least one baffle coupling feature.
15. The baffle of claim 10 , wherein the at least one housing coupling feature comprises a structural support between a proximal end of the at least one housing coupling feature and the outer surface of the at least one wall.
16. The baffle of claim 10 , wherein the at least one housing coupling feature comprises threads disposed in the outer surface of the at least one wall.
17. The baffle of claim 10 , wherein the at least one wall has a conical shape.
18. A housing for a light fixture, the housing comprising:
at least one wall having an inner surface, wherein the inner surface is configured to receive at least a portion of a baffle of the light fixture, wherein the inner surface of the at least one wall has disposed thereon at least one baffle coupling feature,
wherein the at least one baffle coupling feature is configured to detachably couple to at least one housing coupling feature disposed on an outer surface of the baffle of the light fixture, wherein the at least one baffle coupling feature is configured to become coupled to the at least one housing coupling feature when the baffle is rotated in a first direction relative to the at least one wall,
wherein the at least one baffle coupling feature is further configured to become decoupled from the at least one housing coupling feature by rotating the baffle in a second direction that opposes the first direction relative to the at least one wall.
19. The housing of claim 18 , wherein the at least one baffle coupling feature comprises at least one slot, wherein the at least one slot comprises an opening and a detent disposed opposite the opening.
20. The housing of claim 19 , wherein the at least one slot is up to ¼ of a circumference of the inner surface of the at least one wall.
