A lighting apparatus includes a dome housing, a first rotation shaft, a light body, a second rotation shaft and a rotation bracket. The dome housing includes a rim part and a container part. The container part defines a semi-sphere space. The rim part conceals an installation cavity for installing the lighting apparatus. The light body includes a light source. The light body is attached to the container part with the first rotation shaft. The light body is rotatable with respect to the container part along the first rotation shaft for a first rotation direction. The rotation shaft is disposed to the container part with a tilt offset from a top center of the container part. The rotation bracket has a fixing bracket and a central part.

A lighting fixture includes a housing, a first light source, a light guide plate, and a second light source. The housing has an inner cavity and a mounting hole, the mounting hole communicates the inner cavity with an external environment of the housing, the light guide plate is installed in the mounting hole. A side of the light guide plate faces the inner cavity, the other side of the light guide plate faces an outside of the housing. The second light source projects second light to the light guide plate, the second light is capable of being projected to the outside of the housing through the light guide plate. The first light source projects first light, and is configured such that the first light is projected to the outside of the housing through the light guide plate, and the housing is a non-light-transmitting housing.

An LED downlight assembly accommodates square and round trims and its components may be removed irrespective of the presence of mudded in round or square mud plates. The assembly also includes a collar that can be fitted to ceiling of varying thicknesses.

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 fastening device (1) is adapted to fasten a recessed object (30) to a wall. The object has at least one through hole (20) and includes a rod (2), a bracket (3), and a locking element (4). Systems also include at least one fastening device (1) and a recessed object and procedures for the installation of the systems.

An inline driver module includes an input connector, the input connector comprising a live contact and a neutral contact, the live contact configured to connect to a live line of an AC power socket, the neutral contact configured to connect to a neutral line of the AC power socket; an output connector, the output connector comprising a positive contact and a negative contact; and a driver module, the driver module disposed between the input connector and the output connector, the driver module comprising a driver housing and a driver PCB, a driver housing cavity defined within the driver housing, the driver PCB disposed within the driver housing cavity, the driver PCB connected in electrical communication with the live contact, the neutral contact, the positive contact, and the negative contact, the driver PCB configured to convert an AC power input from the AC power socket to a DC power output.

A recessed downlight fixture and method for installation is provided. The recessed downlight fixture can be installed in a retrofit application, after a ceiling is installed, through a pre-existing opening in that ceiling. Alternatively, a recessed downlight fixture according to a second embodiment can be installed before a ceiling is present. In either embodiment, the light source coupled to, for example, a heat sink, can be universally moved in three degrees of movement, rotationally, along a tilt axis, or further within the ceiling to increase or decrease the recess. All such universal adjustments can take place through and below the ceiling opening during or after installation.

Imaging apparatuses and enclosures configured for deployment in connection with ceilings and downlight cavities are disclosed. Certain exemplary aspects relate to imaging apparatuses for monitoring, recording or imaging a space such as a room having overhead lighting provided via ceiling structures that may include enclosures and/or downlight fixtures within ceiling cavities, and various imaging apparatuses herein may include an infrared or thermal camera, for example, for imaging within such spaces.

A sconce box assembly for mounting sconces on walls of various wallboard thicknesses and shallow wall cavities with no disruption to the surrounding wall. The sconce box assembly includes an electrical box having a sidewall, a back wall, an electrical cavity, and wing bosses extending from the sidewall. First rotatable wings secured to the wing bosses are adapted for rotation between a retracted position, in which the rotatable wings are positioned inside the sidewall perimeter, and an extended position in which the rotatable wings are positioned outside the sidewall perimeter. Retracting the wings facilitates insertion of the electrical box through a hole in a wall. Extending the wings facilitates tightening the wings and clamping the electrical box to the wallboard. The invention contemplates at least one second rotatable wing that may be used optionally in place of the first rotatable wing in order to accommodate attachment to various thicknesses of wallboards.

A lighting apparatus equipped with an assembly and support system based on a chain device which allows obtaining the lighting apparatus in various shapes and sizes. The chain device comprises a plurality of links adapted to be together or separated and put on site in an easy and quick manner. Said links may comprise the external protective elements which may be applied to give the link and the chain device a greater strength when assembled to form the lighting apparatus.
