Retrofit and new light-emitting diode (LED) light fixtures for replacement of a fluorescent light fixture
First Claim
1. A kit for retrofitting a light fixture into a rectangular troffer with first and second ends each having a vertical wall portion and a lower horizontal shelf portion extending inward from the vertical wall portion toward the other of the first and second ends, inner surfaces of the vertical wall portions separated by a first distance, the kit comprising:
- a frame for a light fixture, the frame configured to support one or more light sources, the frame having a first end, a second end, and a frame length extending between the first and second ends;
a first mounting member coupled to the frame and configured extend beyond the first end of the frame and be removably coupled to the first end of the troffer to support the frame relative to the first end of the troffer;
a second mounting member coupled to the frame and configured to extend beyond the second end of the frame and be removably coupled to the second end of the troffer to support the frame relative to the second end of the troffer;
two or more mounts, each having a mounting surface and a protrusion extending to an inner end spaced from the mounting surface by a protrusion depth, each mount configured to be coupled to an inner surface of the vertical wall portion of one of the first and second ends of the troffer such that a distance between mounts on opposing ends of the troffer define a mount-opening length that is equal to or less than the first distance less twice the protrusion depth;
where the first mounting member is configured to contact the protrusion of one of the mounts coupled to the first end of the troffer to support the first end of the frame,where the second mounting member is configured to contact the protrusion of another one of the mounts coupled to the second end of the troffer to support the second end of the frame,where at least a portion of the second mounting member is configured to move between an extended first position and a retracted second position in which a distance between the first end of the frame and a distal end of the second mounting member is less than the mount-opening length,where the second mounting member is biased toward the extended first position,where the second mounting member comprises a spring with an upper end fixed to the exterior of the second end of the frame and a lower end movable relative to the second end of the frame, andwhere the lower end of the spring extends through an aperture in an end wall of the frame into an interior of the frame such that a user can pull the lower end of the spring toward the first end of the frame to move the second mounting member to the retracted second position.

Abstract
This disclosure includes kits for retrofitting, or replacing with new, light fixtures using an existing troffer, without using a troffer, and/or including a troffer. Some kits include a frame for a light fixture having a first end, a second end, and a frame length extending between the ends, a first mounting member coupled to the frame and configured to extend beyond the first end of the frame, and a second mounting member coupled to the frame and configured to extend beyond the second end of the frame, where the mounting members are configured to support the frame relative to the troffer. Others of the present kits have a trim configured to support the frame relative to a T-bar support of a suspended ceiling. Some kits have a processor configured to control the light fixtures, and some kits have one or more sensors configured to detect events or environmental characteristics.

15. A method of retrofitting a light fixture into a rectangular troffer with first and second ends each having a vertical wall portion and a lower horizontal shelf portion extending inward from the vertical wall portion toward the other of the first and second ends, inner surfaces of the vertical wall portions separated by a first distance;
- the method comprising;
coupling a first mount to an inner surface of the vertical wall portion of the first end of the troffer; and coupling a second mount to an inner surface of the vertical wall portion of the second end of the troffer, removably coupling a first end of a frame for a light fixture to the first end of the troffer via a mounting member coupled to the frame and configured to extend beyond the first end of the frame to support the frame relative to the first end of the troffer; and removably coupling a second end of a frame for a light fixture to the second end of the troffer via a mounting member coupled to the frame and configured to extend beyond the second end of the frame to support the frame relative to the second end of the troffer; where each mount has a mounting surface facing the inner surface of the respective vertical wall portion and a protrusion extending to an inner end spaced from the mounting surface by a protrusion depth such that a distance between mounts on opposing ends of the troffer define a mount-opening length that is equal to or less than the first distance less twice the protrusion depth, where the first mounting member is coupled to the fast end of the troffer via contact with the protrusion of the mount coupled to the first end of the troffer, and the second mounting member is coupled to the second end of the troffer via contact with the protrusion of the mount coupled to the second end of the troffer, where the first mounting member is configured to contact the protrusion of one of the mounts coupled to the first end of the troffer to support the first end of the frame, where the second mounting member is configured to contact the protrusion of another one of the mounts coupled to the second end of the troffer to support the second end of the frame, where at least a portion of the second mounting member is configured to move between an extended first position and a retracted second position in which a distance between the first end of the frame and a distal end of the second mounting member is less than the mount-opening length, where the second mounting member is biased toward the extended first position, where the second mounting member comprises a spring with an upper end fixed to the exterior of the second end of the frame and a lower end movable relative to the second end of the frame, where the lower end of the spring, extends through an aperture in an end wall of the frame into an interior of the frame such that a user can pull the lower end of the spring toward the first end of the frame to move the second mounting member to the retracted second position, and where the frame is configured to support one or more light sources. - View Dependent Claims (16, 17, 18, 19)
