The present disclosures provides a collar for positioning at least partially around a recessed light fitting and between the recessed light fitting and a structural body. The collar comprises a plurality of collar portions each of which are configured to surround a portion of the recessed light fitting.

A linear light fixture assembly for supporting a light fixture in a ceiling structure, comprises a light fixture mounting structure having a pair of opposed boundary regions configured to fit within a designated light fixture receiving region in the ceiling structure, and a plurality of spring elements configured to spaced outwardly from at least one of the boundary regions, each spring element having a mounting region configured to be anchored to the mounting structure and a free end region to extend therefrom and to be laterally outwardly biased in a first position to form a path of contact with a support surface region on the ceiling structure to anchor the structure in the receiving region, each of the spring elements configured to be movable toward the corresponding boundary region in a second position to release the path of contact to release the light fixture from the receiving region.

A baffle component for a luminaire includes a portion of opaque material that forms a front surface and a back surface as major surfaces. The front surface includes multiple ridges. The material also includes a top surface and a bottom surface, and a first end surface and a second end surface. The first end surface includes a first coupling feature, and the second end surface includes a second coupling feature that is configured to engage the first coupling feature of a second baffle component that is substantially identical to the baffle component. A baffle for a luminaire includes a plurality of such components. The baffle components engage with one another, with the first coupling feature of each of the baffle components engaging with the second coupling feature of another of the baffle components, to form a shape that surrounds a central opening of the luminaire.

A retrofit trim lighting device is provided. In example embodiments, the retrofit trim lighting device comprises a bracket comprising an opening; at least one torsion spring secured to the bracket and configured to mount the retrofit trim lighting device within a recessed housing; a retrofit housing comprising at least one light engine; and an engagement element. The engagement element is secured to the retrofit housing through the opening of the bracket such that, when so secured, the retrofit housing and the bracket are rotatable relative to one another.

The present invention discloses a panel light mounting structure, a panel light and mounting method thereof. The panel light mounting structure comprises a fixing slot disposed on the back of the light body and a mounting bracket to snap-connect with the matching fixing slot. The present invention adopts a sliding and snap-in method to match and connect the panel light body with the mounting bracket. The installation is easy and fast, and the ceiling-mount effect is excellent. In addition, the present invention may also achieve the blinds operation during the panel light installation process.

An installable and dismantlable apparatus provided by the present invention includes: a load bearing part, a toggle assembly rotatably disposed on the load bearing part and a fixing assembly movably disposed on the load bearing part, and the fixing assembly is driven to move for fixing while the toggle assembly rotates. Through the use together of the load bearing part, the toggle assembly and the fixing assembly, while installed, the toggle assembly rotates and the fixing assembly is driven to move, and then the fixing assembly acts on another part for fixing; while dismantled, only the fixing assembly needs to be pushed towards its initial position, which not only ensures the convenience, reliability and firmness during the installation and fixation, but also saves manpower; and in practical use it is easy to operate and convenient for workers to install and dismantle quickly while ensuring the fixing effect.

Light systems, systems and apparatus related thereto that aids in the installation and removal of a luminaire as well as eliminates gaps formed in a housing for the light system. The light system includes a spring-loaded attachment system for a light system, a mounting system in which a luminaire can be arranged therein that includes interchangeable plates to accommodate various size and shape luminaires, and a light-blocking rotatable housing assembly for a recessed luminaire.

An assembly for an opening through a member has a body and a first spring retention assembly coupled to the body. The first spring retention assembly has a first coil spring at least partially disposed within a first spring housing. The first coil spring has a first end extending through the first spring housing and is coupled to the body. The first coil spring is extendable from and retractable into the first spring housing.

Luminaire (1) comprising suspension means (3) and a housing (5) with a top wall (7). Said suspension means (3) comprising a hook (9a, b) formed of an elastic wire (11) with a loop portion (15) connected to two remote, oppositely arranged end portions (13a, b) each forming a spindle (17a, b), and two elongated channel elements (19a, b) arranged along a rotation axis (21) and mounted on the top wall (7), with each spindle (17a, b) being snugly fitted in a respective channel element (19a, b). By a mutual misalignment between the spindles (17a, b) and the channel element (19a, b) with respect to the rotation axis (21), the hook (9a, b) is in a low tension state when in a first rotational position (27), and in a high tension state when in further rotational positions (29) and urging the hook (9a, b) to assume the first rotational position (27).

A linear light fixture assembly for supporting a light fixture in a ceiling structure, comprises a light fixture mounting structure having a pair of opposed boundary regions configured to fit within a designated light fixture receiving region in the ceiling structure, and a plurality of spring elements configured to spaced outwardly from at least one of the boundary regions, each spring element having a mounting region configured to be anchored to the mounting structure and a free end region to extend therefrom and to be laterally outwardly biased in a first position to form a path of contact with a support surface region on the ceiling structure to anchor the structure in the receiving region, each of the spring elements configured to be movable toward the corresponding boundary region in a second position to release the path of contact to release the light fixture from the receiving region.
