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.

A luminaire featuring a light diffusing housing assembly with a batwing style catadioptric lens element with properties capable of producing a more uniform field of illumination in concert with a secondary diffusing lens element and optional internal light reflecting elements to maximize light output from a point light source including an LED, or a plurality of individual point light sources including an LED strip or LED array and other source of linear chromatic light or linear illumination sources including a light bar, fluorescent lamp, compressed-gas discharge tube and the like.

Disclosed is a grid lighting system having at least one housing segment with at least one lighting zone. At least one lighting module is selected from at least one track lighting module and/or at least one non-track lighting module. The at least one lighting zone extends along a first length dimension of the housing segment and including at least one first passage to receive the at least one track lighting module and/or non-track lighting module. The housing segment includes a first power supply segment to be coupled with a designated line voltage outlet to deliver line voltage power to the at least one lighting module in the at least one lighting zone. Each track lighting module includes a lighting subzone, with a second passage to receive one or more lighting submodules along a second length dimension. A second power supply segment is provided to couple with the first power supply segment to receive line power and to deliver low voltage to the one or more lighting submodules.

A lamp holder assembly includes a support post, and a plurality of fixtures mounted on the support post. The support post includes a main body and a securing portion. The main body has a plurality of entrance slots. Each of the entrance slots has two limit grooves. Each of the fixtures includes a mounting head and a locking member. The locking member is inserted into each of the entrance slots and is introduced from each of the entrance slots into the two limit grooves of each of the entrance slots by rotation of each of the fixtures, and is locked in the two limit grooves of each of the entrance slots. The locking member is provided with two pressing pieces. When each of the fixtures is rotated, the pressing pieces are locked into the limit grooves of each of the entrance slots.
