Abstract: A device for mounting a light fixture structure to a ceiling grid. The device includes an anchor structure extending from the light fixture structure, with a pair of arm structures spaced to receive a ceiling grid segment therebetween at an anchor location on the ceiling grid adjacent a lower region of the ceiling grid. The arm structures have respective distal regions configured to be accessible from an upper region of the ceiling grid and a clamp structure configured to traverse laterally relative to the distal regions to couple with the respective distal end regions and thereafter to be transferable between a released position and a locked position. When in the locked position, the ceiling grid segment held between the anchor and clamp structures place the light fixture structure in the mounted position.

Abstract: Disclosed is a coupling assembly for joining together a pair of light fixture segments at a joint interface therebetween to form a light fixture assembly, comprising a body rotatably mountable on a first of the light fixture segments about a central axis, the body configured to operably engage a drive tool with a drive axis thereof aligned with the central axis to rotate the body between a release position and a coupling position, the body having a designated receiving location to receive a complementary coupling element on a second of the light fixture segments, and configured to provide an arcuate pathway extending from designated receiving location, wherein the designated receiving location and pathway are configured to permit the complementary coupling element to travel along the pathway as the body rotates on the central axis, and thereby to laterally transfer the complementary coupling element radially toward the central axis to draw the first and second light fixture segment toward forming the joint in
