Direct drive optic tilt mechanism for recessed luminaire
A direct drive optic tilt mechanism for a recessed luminaire can include a frame comprising a frame body, a first frame extension, and a second frame extension, wherein the frame body is configured to receive a housing of the recessed luminaire. The direct drive optic tilt mechanism can also include a bracket movably coupled to the frame, wherein the bracket comprises a bracket base, a first bracket extension, and a second bracket extension, wherein the bracket base has a bracket base opening that traverses therethrough and that is configured to allow light from a light source of the recessed luminaire to pass therethrough. The direct drive optic tilt mechanism can further include a drive assembly coupled to the frame and the bracket, wherein the drive assembly comprises a tilt arm, an anchor, a drive mechanism, and a shaft coupled to a proximal end of the tilt arm.
1 . A direct drive optic tilt mechanism for a recessed luminaire, the direct drive optic tilt mechanism comprising:
a frame comprising a frame body, a first frame extension, and a second frame extension, wherein the first frame extension and the second frame extension are located at opposite ends of the frame body, wherein the first frame extension includes a first aperture and a second aperture and the second frame extension includes a third aperture and a fourth aperture;
a bracket movably coupled to the frame, wherein the bracket comprises a bracket base, a first bracket extension, and a second bracket extension, wherein the bracket base has a bracket base opening that traverses therethrough, wherein the first bracket extension and the second bracket extension are located at opposite ends of the bracket base,
wherein the first bracket extension comprises a first curved slot that is configured to be movably coupled to the first aperture in the first frame extension of the frame and a second curved slot that is configured to be movably coupled to the second aperture in the first frame extension of the frame, and
wherein the second bracket extension comprises a third curved slot that is configured to be movably coupled to the third aperture in the second frame extension of the frame and a fourth curved slot that is configured to be movably coupled to the fourth aperture in the second frame extension of the frame; and
a drive assembly, wherein the drive assembly comprises a tilt arm, a drive mechanism, and a stop feature with one end of the stop feature coupled to the first frame extension and another end of the stop feature coupled to the first bracket extension, wherein movement of the drive mechanism changes an angle between the bracket and the frame.
2 . The direct drive optic tilt mechanism of claim 1 , further comprising:
a first protrusion disposed in the first aperture, the first curved slot, and a tilt arm aperture in the tilt arm of the drive assembly;
a second protrusion disposed in the second aperture and the second curved slot;
a third protrusion disposed in the third aperture and the third curved slot; and
a fourth protrusion disposed in the fourth aperture and the fourth curved slot.
3 . The direct drive optic tilt mechanism of claim 1 , wherein the bracket base opening of the bracket base has a bracket base center point, wherein the bracket base center point is intersected by a center axis along a frame body center point in a frame body opening in the frame body to form the angle.
4 . The direct drive optic tilt mechanism of claim 3 , wherein the bracket base center point is intersected by the center axis along the frame body center point in the frame body opening in the frame body through an entire range of motion of the frame relative to the bracket.
5 . The direct drive optic tilt mechanism of claim 4 , wherein the frame body opening is configured to have disposed therein a housing of the recessed luminaire.
6 . The direct drive optic tilt mechanism of claim 1 , wherein the tilt arm of the drive assembly includes a tilt arm aperture.
7 . The direct drive optic tilt mechanism of claim 1 , wherein the angle is adjustable between 0° and 45°.
8 . The direct drive optic tilt mechanism of claim 1 , wherein the drive mechanism is configured to be accessible through the bracket base opening, and wherein the drive mechanism is positioned between the bracket base and the frame body.
9 . The direct drive optic tilt mechanism of claim 1 , wherein the drive mechanism is operable using a tool.
10 . The direct drive optic tilt mechanism of claim 1 , wherein the first curved slot in the first bracket extension of the bracket is configured to be positioned closer to the frame body than the second curved slot in the first bracket extension of the bracket.
11 . The direct drive optic tilt mechanism of claim 1 , wherein the drive assembly further comprises a gear assembly to rotate the tilt arm.
12 . The direct drive optic tilt mechanism of claim 1 , wherein the drive assembly further comprises a U-shaped drive bracket, a rotatable extension of the drive mechanism that is disposed in at least one distal end of the U-shaped drive bracket, and a carrier, wherein the carrier moves along the extension as the extension rotates, wherein the carrier is coupled to a proximal end of the tilt arm of the drive assembly, and wherein the tilt arm rotates as the carrier moves along the extension as the extension rotates.
13 . The direct drive optic tilt mechanism of claim 12 , wherein the U-shaped drive bracket of the drive assembly is rigid and coupled to the bracket base.
14 . The direct drive optic tilt mechanism of claim 1 , wherein the tilt arm of the drive assembly is positioned adjacent to an outer surface of the first bracket extension.
15 . The direct drive optic tilt mechanism of claim 1 , wherein a force of the stop feature is opposed by a position of the drive mechanism.
16 . The direct drive optic tilt mechanism of claim 1 , wherein the stop feature is a spring.
