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.

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 modular lighting device may mounted into architectural finished surfaces such as ceilings, walls and floors. The device comprising an adjustable mounting mechanism that allows the lighting device to be fitted to various sized openings in a surface. One version of the modular lighting device includes a plate for receiving a lamp fitting, three mounting brackets, and a locking ring for restraining the mounting brackets to the plate, wherein the modular lightning device is configured such that it can be fitted to different sized openings via radial adjustment of the mounting brackets.

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 light assembly mountable in an aperture formed in a railing or a light fixture. The light assembly may include a housing, first and second clamps, and first and second fasteners. The first fastener may couple the first clamp to the housing, and the second fastener may couple the second clamp to the housing. When the fasteners are rotated, the respective clamps pivot outward and move towards the railing or light fixture to retain the light assembly in the railing or the fixture. The light assembly may be removable from the aperture in the railing or the fixture.

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 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.
