A trim member for a lighting device module includes an annular body having a first end portion that is connectable to a housing of the lighting device module and has a light receiving opening, and a second end portion opposite to the first end portion. The second end portion has a light emitting opening and is configured to be positioned outside of the housing of the lighting device module. A first curved or tapered surface extends from the light receiving opening toward the light emitting opening, and has a diameter that increases toward the light receiving opening. A second curved or tapered surface extends from the first curved or tapered surface to the light emitting opening, and has a diameter that increases toward the light emitting opening.

A mounting plate assembly has a mounting plate for mounting a light fixture in holes of different diameters and wherein a guide rail assembly is secured to a rear face of the mounting plate on opposed sides of an aperture. Each guide rail assembly has a novel displaceable spring clamp structure having to a displaceable base coupled for sliding displacement along a guide rail assembly. Spring biasing elements are provided between the displaceable base and the guide rail assembly to urge a bottom face of the displaceable base against a flat top surface of a mounting base to which the guide rails are secured. A retention formation is provided in the bottom surface of the displaceable base for retention coupling with a selected one of space-apart engageable retainers immovably secured to the flat top surface of the mounting base and aligned with the retention formation to arrest the displaceable base at a desired location to position the spring clamp structures at a desired location with respect to the size of a hole formed in the sheet material and to which a light fixture is to be secured.

The present invention relates to a built-in light and/or camera (1) for arrangement in an installation opening (4) of a wall (5), in particular an inner wall of a machine, having a housing (10) with a front side area (12), a rear side area (14) and side walls (15, 16, 17, 18), wherein at least one camera (30) and/or at least one light source (40) is arranged in the front side area (12), wherein a stop (20) is arranged in the front side area (12), wherein at least one fastening (50) is provided that protrudes over one of the side walls (15, 16, 17, 18), and wherein the at least one fastening (50) is configured to form a spring-loaded form fit of the wall (5) between the stop (20) and the at least one fastening (50) like a trap when inserted into the installation opening (4).

A mounting plate assembly has a mounting plate for mounting a light fixture in holes of different diameters. A guide rail assembly is secured to a rear face of the mounting plate on opposed sides of an aperture. Each guide rail assembly has a displaceable spring clamp structure mounted on a displaceable base coupled for sliding displacement along the guide rail assembly. Spring biasing elements are provided between the displaceable base and the guide rail assembly to urge a bottom face of the displaceable base against a flat top surface of a mounting base to which the guide rails are secured. A retention formation is provided in the bottom surface of the displaceable base for retention coupling with a selected one of space-apart engageable retainers immovably secured to the flat top surface of the mounting base and aligned with the retention formation to arrest the displaceable base at a desired location to position the spring clamp structures at a desired location with respect to the size of a hole formed in the sheet material and to which a light fixture is to be secured.

A lamp installation structure of a ceiling fan has a first base connected to a fixing seat of the ceiling fan and a second base connected to a lamp. The first base is provided with a plurality of positioning members. The second base has grooves and guide rails corresponding to the positioning members for insertion of the positioning members. The guide rails are provided with a plurality of elastic members to elastically press against the positioning members. Thereby, through the positioning members being retained to the guide rails, the lamp installation structure of the ceiling fan has the advantages of quick installation and increased stability of the ceiling fan.

A flush mount LED bolt providing has a cylindrical housing having a first end and a second end, the cylindrical housing includes a housing diameter and a housing length, and wherein at least a portion of the cylindrical housing includes threads. A bezel is positioned at the first end of the cylindrical housing. The bezel includes a top surface and a rear surface. The bezel's shape and design may vary. An LED light is provided. The LED light may vary in color, brightness, etc. depending on the desired application. During installation, the cylindrical housing is configured to be inserted through a mounting hole on a mounting surface and the rear surface of the bezel is configured to mounted flush with the mounting surface creating a low profile installed LED bolt with only the bezel visible.

A reflector and of a holding-plate slidingly attach to each other to form a flangeless trim assembly. The reflector may be removably attached to a spackle-frame. The spackle-frame may be installed within ceiling drywall around a hole for a downlight. The holding-plate may be attached to a lighting module. In a default resting configuration, a top of the reflector butts up against a bottom of the holding-plate because springs push these two parts towards each other. When an opposing force is applied that is greater than the spring's force, then a variable gap is formed between the reflector and the holding-plate, but while the reflector and the holding-plate are still attached to each other. This gap may be used by human finger(s) to both disengage the reflector from the spackle-frame and to pull down the reflector, the holding-plate, and the lighting module from the spackle-frame—all without tools.

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.

Proposed is a slim-type LED lighting apparatus with integrated junction box and LED module. The apparatus includes: the junction box having a plurality of first cable inlets that allow circular cables or conduits to be introduced thereinto and are arranged on a circumference of a side surface of a cylindrical body with an open upper side and a recessed lower side, an upper opening into which a wiring cover is coupled to be selectively openable and closable for wiring work, and a lower recess having a first flange protruding from the cylindrical body; the LED module inserted through the lower recess of the junction box and then integrally coupled to a lower surface of the junction box in face-to-face contact therewith; and a plurality of interchangeable trims of different diameters selectively coupled to a lower portion of the junction box and configured to be interchangeable with each other.

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.
