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 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 recessed lamp which includes a surface ring defining a light exit opening, a diffusing plate, and a light emitting assembly. The surface ring has an inner side surface, an outer side surface, and a protruding ring arranged on the inner side surface to surround the light exiting opening. The diffusing plate is positioned to abut against the inner side of the surface ring to cover the light exiting opening, and is fusion sealed to the surface ring. The light emitting assembly includes a plurality of LED lamp beads arranged on a substrate to emit light towards the light exiting opening.

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 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.

A surface mount assembly for mounting a device in a surface opening of a mounting surface includes a frame, a number of locking mechanisms, and a cam ring. Each locking mechanism includes a locking member, a locker, and a coil spring. The cam ring shifts the locker rearward to move the locking member to a deployed orientation when the cam ring is rotated in one direction. The coil spring pushes the locking member to a deployed position against a back side of the mounting surface when the locking member moves to the deployed orientation. The cam ring shifts the locker forward to secure the locking member in the deployed position when the cam is rotated in a second direction opposite the first direction.

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 ceiling lamp includes a top plate, a ceiling shell, an air guide shell, a main shell and a lampshade. A first accommodation cavity is formed between the ceiling shell and the air guide shell. A second accommodation cavity is formed with the lampshade. An illuminant board is configured in the second accommodation cavity. A fan is configured coaxially on the axis of the air guide shell. An air passage connected with the fan is opened on the lampshade by invagination along the axial direction of the lampshade. At least one air hole is formed on air guide shell. A filter screen module is detachably configured in the air passage. The external air flow is discharged from the air hole through the fan by the filter module, or enters from the air hole and then discharges through the filter module after passing through the fan.

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.
