A plurality of shipper light boxes are each configured to be coupled to a respective sorter light box and also positioned at the respective shelf. A hub is coupled to a first sorter light box in the chain and operates as a concentrator of control signals and power for the plurality of sorter light boxes in the chain. A power supply is configured to be coupled to the hub and supply power to the sorter light boxes and shipper light boxes. A controller is configured to be coupled to the hub and generate the control signals for the sorter light boxes in the chain of sorter light boxes based upon commands received via an externally coupled network, and a repeater is configured to be coupled within the chain to push power along the chain.

A downlight apparatus is designed to be installed in a cavity of a ceiling. The downlight apparatus includes a base part, a major part and a connector. The base part has a shape to be fixed in the cavity of the ceiling. The base part has a base housing for defining a through hole and a light window. The major part includes a major housing, a light source and a driver circuit. The connector connects the major housing and the base housing. The connector provides multiple candidate positions for a user to configure to change a relative position of the base part and the major part so as to change an output light defined determined by the light window and the light source.

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.

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.

A light fixture assembly for mounting on a mounting surface of a building material includes: a light fixture. The light fixture comprises a main body comprising a back side surface and a light transmissive side surface opposing the back side surface. The main body has a first dimension from a first lateral edge to a second lateral edge opposing the first lateral edge that is greater than a second dimension from the back side surface to the light transmissive side surface. The assembly further includes a mounting adapter provided at the back side surface, and a plate spring provided at the back side surface and extending along a first direction from the first lateral edge to the second lateral edge. The plate spring is configured to apply a restoring force to the first lateral edge and the second lateral edge.

A light fixture is configured for mounting within a given housing-can. The light fixture may have a driver assembly, a heat-sink and a trim-casing assembly. The driver assembly may have a driver-printed-circuit-board, a lumen-switch, a color-temperature-switch, and a driver-box. The driver-printed-circuit-board, the lumen-switch, and the color-temperature-switch may be at least partially housed within the driver-box. With the lumen-switch, a lumen output of the light fixture may be selected. With the color-temperature-switch, a light color-temperature output of the light fixture may be selected. The trim-casing assembly may have a light-emitting-diode-circuit, a reflector, a lens, a can-attachment-means, and a trim-casing-member. The light-emitting-diode-circuit, the reflector, and the lens may be housed within the trim-casing-member. The can-attachment-means may be attached to an exterior of the trim-casing-member and is for attaching the light fixture to the housing-can. The heat-sink may be disposed between the driver assembly and the trim-casing-assembly.

A lighting-junction-box-assembly-for-remodel (assembly) has a lighting-junction-box, leg-springs attached to the lighting-junction-box, and mounting-tabs attached to the lighting-junction-box. The leg-springs are used to (temporarily) hold (by friction) the assembly within a hole in an existing ceiling, sized to fit the assembly. While the leg-springs are (temporarily) holding the assembly within the hole in the existing ceiling, other/different holes within extension-portions of the mounting-tabs are used to secure the entire assembly to the existing ceiling, via mechanical fasteners passing through the extension-portion holes and into the existing ceiling. An existing ceiling may be retrofitted with this assembly to have a lighting-junction-box where desired/needed in that existing ceiling; and as such, this assembly is particularly useful in remodeling situations (applications); however, the assembly may also be used in new construction. The assembly may also include a second junction-box to offload some of the circuitry that would otherwise be included within a lighting can.
