A light fixture includes a supporting unit including two supporting arms, and multiple illumination assemblies connected between the supporting arms. Each illumination assembly includes a heat dissipation unit, an illumination module and a controlling module. The heat dissipation unit includes a base plate and multiple fins. The illumination module includes a light-permeable cover unit, and an illumination unit disposed between the cover unit and the base plate. The illumination unit includes multiple illumination elements. The controlling module is mounted to the heat dissipation unit, and includes a box unit and a circuit board unit received in the box unit and coupled to the illumination unit for controlling operation of the illumination elements.

According to one embodiment, a lighting device includes: a first housing in which a lamp unit is provided; a second housing in which a power supply unit is provided; and a hinge member that allows the first housing to be capable of opening and closing with respect to the second housing.

A recessed lighting system is disclosed that is capable of providing both direct and indirect lighting. The recessed lighting system may include first and second pluralities of light emitting diodes (LEDs) mounted on, respectively, first and second elongate track members. The first and second elongate track members may be spaced apart from each other by a distance, and a reflector may span at least a portion of that distance. The first and second pluralities of LEDs may be configured to emit light toward the reflector so that the reflector provides indirect lighting. A direct lighting fixture may be arranged between and slidably supported by the first and second elongate track members so that the direct lighting fixture is movable along the first and second elongate track members. Accordingly, the direct lighting fixture can be moved to a preferred position to spotlight an individual object or portion of the room.

Improved soft lighting systems for the arts, media, and entertainment industry are disclosed. In certain aspects, the systems employ one or more edge-lit LED light guide panels using high flux, optical grade, and/or binned LEDs to produce higher quality, uniform, diffused soft visual media light. In further preferred aspects the systems are modular and portable, and have light guide panels that may be axially tilted in horizontal and vertical directions to independently direct the soft light emanating from each of the panels to achieve the desired soft lighting set up.

A pendant lighting fixture can include an outer casing, a hollow body positioned within the outer casing, a motion generator positioned within the hollow body, and an illumination assembly within a chamber formed by a cover. An upper part of the hollow body is configured to be coupled to a hanging mechanism, and a lower part of the hollow body is removably coupled to the cover. The motion generator comprises a container, a magnetic coil configured to generate a magnetic field, and an object movably responsive to the magnetic field move within the container so that a movement of the object of the motion generator by the magnetic field affects an illumination effect of the illumination assembly.

The present disclosure relates to the technical field of lamp bulbs, and discloses a lamp panel plugged type light-emitting diode (LED) lamp bulb, including a lamp holder and a lamp bulb shell fixedly connected to the lamp holder, and further including an insulation fixed seat and a lamp panel type light source assembly for vertical mounting; the insulation fixed seat is arranged at an opening portion of the lamp bulb shell; the insulation fixed seat at least includes an assembling portion and a plugging portion configured to mount the lamp panel type light source assembly; the plugging portion is provided with a plugging slot; at least two conductive contacts a are provided on an inner side of the plugging slot; one conductive contact a is electrically connected to a positive electrode of the lamp holder.

The invention relates to a light fixture (1) comprising an elongated carrier element (5), a number of lighting modules (20), which can be detachably secured to the carrier element (5), and means for supplying power to the lighting module (20), said means comprising an operating device (100) and contacting means (40, 41) which are connected to said operating device (100) and to which the lighting modules (20) can be electrically connected. In said light fixture, the operating device (100) and the contacting means (40, 41) are arranged on a device carrier (50) that can be detachably secured to the carrier element (5).

A plurality of LED light fixtures are mounted in a ceiling of an auditorium and a power control system is positioned in an area separate from a seating area of the auditorium for supplying power to the LED light fixtures. Each LED light fixture comprises an extrusion carrying one or more ambience light LED modules for providing ambient light and one or more high intensity LED modules for providing full level lighting. The power control system is configured to collectively switch the ambience light LED modules on and off and to separately and collectively switch the high intensity LED modules on and off to thereby provide either low level ambient light or high intensity full level lighting to the auditorium.

A modular lighting system may include a support structure, a plurality of heat sink modules physically supported by the support structure, and one or more light source modules coupled to the plurality of heat sink modules. The plurality of heat sink modules may be arranged in a modular manner such that the number of heat sink modules in the modular lighting system is variable, and each heat sink module may be an integral molded structure defining at least one opening or passageway.

An endcap, e.g. for a linear luminaire. The endcap has projecting structure attached to and projecting from an inner surface thereof. The projecting structure defines at least two positions aligned with and spaced from one another along the inner surface. One or more crush ribs are connected to the projecting structure at each of the at least two positions. A trough is recessed into the inner surface of the endcap and surrounds at least a portion of each of the at least two positions. The trough provides space to receive any material that is separated from the one or more crush ribs when the endcap is inserted into a channel.
