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 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.

An overall-assembly of a downlight, with a flangeless trim, and a spackle-frame have complementary structures for repeatably attaching or detaching the downlight to the spackle-frame merely by pushing the downlight into a central hole of the spackle-frame and without use of any external / separate tools. The flangeless trim has some upward protruding members that are configured to removably attached / detached to clips and housings-for-clips. The clips are housed within the housings-for-clips. And the clips and the housings-for-clips are retained in structures of the spackle-frame. The spackle-frame would typically be permanently installed within an appropriately sized hole in drywall (or the like), such as, but not limited to, ceiling drywall. In this way, such downlights may be readily installed or removed and all without use of external / separate tools.

A downlight structure includes a light body and a light source (5). The light body includes a support (1), a movable light holder assembly (2), a base (3), and a supporting ring (4). The movable light holder assembly (2) is movably connected to a top of the support (1). The base (3) is arranged at a bottom of the support (1) after connected to the supporting ring (4). The light source (5) is arranged on the movable light holder assembly (2), and moves longitudinally or horizontally in the light with the movable light holder assembly (2). Through delicate design of the structure of the light body and the light source (5) of the downlight, the present disclosure provides a convenient solution for replacing the light source of the downlight with bare hands, and also provides a feasible solution for standardization of the downlight industry.

A light includes a body, a front housing secured to a front end of the body, a translating retainer rotatably engaged with the front housing, a slip ring positioned around the front housing and between the translating member and the front end of the body, a compressible ring positioned around the front housing and between the slip ring and the front end of the body, a lens mounted to the front housing, an electronic assembly, and a light emitting element in electrical communication with the electronic assembly and positioned within the lens. Rotation of the translating retainer in a first direction causes the translating retainer to drive the slip ring toward the front end of the body, compressing the compressible ring and causing the compressible ring to bulge outward to contact, and removably engage, an inner wall of a pipe or conduit that the light is positioned in.

An LED downlighting apparatus includes a housing with a sidewall having a front facing edge and a back facing edge positioned adjacent to a ceiling when the LED downlighting apparatus is installed in an opening of the ceiling. A depth of the sidewall is less than one inch and a thickness of at least a portion of the sidewall is less than three millimeters. An LED board and a lens are coupled to the housing. The lens is disposed with respect to the LED board such that the lens is illuminated from a back side. One or more mechanical couplers snap fit the apparatus to a junction box installed and positioned above the ceiling such that when the apparatus is snap fit to the junction box through the opening of the ceiling, the housing appears to be surface mounted to the ceiling.

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 integrated ceiling device includes integrated ceiling device including an electronic device housing, a heat dissipating structure, a light source, and a reflection/refraction assembly. An air gap is defined between the electronics housing and other components allowing ambient air to flow therethrough for cooling.

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 fireproof recessed light fixture for receiving a light source comprises a metal housing defining an open end for receiving the light source and a closed end. The housing comprises an annular shoulder at the open end for abutting a wall into which the recessed light fixture is installed. The housing comprises a first wall of generally cylindrical shape extending between the open and closed ends and a second wall defining the closed end of the housing. Both first and second walls have thicknesses between 0.5 and 1 mm and are completely sealed so to prevent air flow between an interior and an exterior of the housing other than through the open end and through an opening for feeding through cables for electrical energy supply. The first and second walls render the recessed light fixture fireproof by preventing high temperatures or fire from propagating quickly through the housing.
