A downlight apparatus includes a fixing bar, a driver box, a light container and a light source. The fixing bar has two elastic units and a central part. The two elastic units are located at two opposite sides of the central part. The two elastic units are deformed so as to pass through a central hole of a fixing plate and then are released to attach to the fixing plate. The fixing plate is fixed to a platform. The driver box includes a driver for converting an external power to a driving current. The light container has a top cover and a lateral wall. The fixing bar is fixed on the top cover protruding toward the central hole of the fixing plate. A bottom side of the driver box is placed on the central part.

A downlight apparatus includes a light source, a driver, a light holder, a metal rim and two elastic arms. The driver converts an external power to a driving current to be used by the light source. The light holder stores the light source in an holder space of the light holder. The light holder is placed inside a cavity of a ceiling. The metal rim is connected to a bottom side of the light holder. The two elastic arms are attached to one of the metal rim and the light holder for elastically pressing the metal rim to engage an cavity edge of the cavity of the ceiling for concealing the cavity and preventing an accidental fire to escape from the cavity of the ceiling to outside of the cavity of the ceiling.

A light fixture includes a visible light module and a germicidal light module. The visible light module may include one or more visible light engines designed for emitting visible light for general illumination. The visible light module may define a top side, a bottom side opposite the top side, and an outer perimeter around the top side and the bottom side. The visible light module may define an aperture extending through the visible light module from the top side to the bottom side. The visible light module may be designed to emit the visible light out of and across the bottom side from the outer perimeter to an inner perimeter defined by the aperture. The germicidal light module may be coupled to the visible light module. The germicidal light module includes a germicidal light engine designed to emit germicidal light through the aperture effective in deactivating pathogens.

The present invention may be directed to an improved LED downlight with enhanced features including a multi-adjustable junction box and cover assembly, and arm and hinge mechanisms for better installation and packaging of said improved LED downlight. The versatile configuration of the junction box, mounting plate arm, and hinge mechanisms may allow the entire assembly to be maneuvered over various sized ceiling holes for ease of driver and LED replacement and maintenance. Other features and improvements may include compact compressible and expandable three-piece hangar bar mounting brackets, an integral air-tight box, and/or a system for mounting the improved LED downlight to various ceiling thicknesses. The improved LED downlight may be used in both new construction and remodel retrofit installations, sharing the majority of parts, providing ease and flexibility for the installer.

A lighting device includes a plurality of main bodies, a first casing, a plurality of second casings, a control module, and a plurality of light-emitting modules. One side of each of the plurality of main bodies has the light-emitting modules arranged thereon, and the light-emitting module is electrically connected to the control module. One second casing is fixedly disposed on another side of each of the plurality of main bodies that is opposite to the one side where the light-emitting module is disposed, and a passage is formed between the second casing and the main body. The control module with a plug-in design is disposed in the first casing, so that the control module is arranged away from the plurality of light-emitting modules.

A strip lamp includes an illuminating lamp and a power supply module. The illuminating lamp includes a lamp body, a light guide plate, a control panel, an LED lamp panel and a PCBA mainboard. The LED lamp panel and the PCBA mainboard are installed in the lamp body. The light guide plate is disposed over the lamp body and is located on a light emitting side of the LED lamp panel. The PCBA mainboard is provided with a first interface at an end of the lamp body. An opening matched with the first interface is formed in a position, closed to the first interface, of the lamp body. The charging PCB is provided with a second interface extending out of a connector of the power supply module. The independent rechargeable power supply module is used to supply power to the illuminating lamp.

The present disclosure discloses a hiding fan, the hiding fan includes a turntable, a plurality of fan blades, and a synchronization mechanism, the synchronization mechanism includes a rotation ring and a plurality of connection rods, the rotation ring is mounted on the turntable, the rotation ring can rotate relative to the turntable around a central axis of the turntable, each fan blade has an installation end and a free end, the installation end has an installation portion and a connection portion, the installation portion is mounted on the turntable through a first rotation connection portion, a first end of the connection rod is mounted on the turntable on the rotation ring through a second rotation connection portion, a second end of the connection rods is mounted on the connection portion, the fan blade can rotate around a central axis of the first rotation connection portion.

An annular LED grow light is disclosed, which comprises a radiator, a light source board, and a power supply box. The light source board is composed of a PCB light board and a plurality of LED lamp beads, wherein the LED lamp beads are arranged on the PCB light board in an annular array about a center. The beneficial effects of the present disclosure are: the photosynthetic photon flux density (PPFD) is distributed more evenly after the LED lamp beads are arranged in an annular array about the center, thus the effective irradiated area is larger, and the cost has been saved.

A lighting system comprises a support cable having two conductive wires only; a plurality of fastening elements for supporting the cable along a path; a plurality of coupling elements fixable to the cable and having respective pairs of contacts which draw current from the cable; and a plurality of lighting devices coupled to respective coupling elements; each fastening element is provided with a printed circuit board, connected to the contacts and to the lighting device coupled to the fastening element and comprising a DC converter; a dimmer; and a Bluetooth module for receiving and processing signals from an external control device; the board is configured to receive current from the cable and generate a dimmed direct current which supplies the lighting device connected to the board.

A light emitting apparatus includes a light source, a unitary formed heat sink with a plurality of heat dissipating fins, a lensed enclosure that retains a light source and at least one power consuming device other than the light source.
