The LED module is mounted between the heatsink disk and the light output module. The LED driver is connected with the LED module.

A mounting bracket for a ceiling lamp includes a support frame and a lamp bracket body removably mounted on the support frame. The support frame includes a frame body, a locking hook mounted on a first side of the frame body, and a limit locking plate mounted on a second side of the frame body. The limit locking plate includes a fixed portion secured to the frame body, a connecting portion connected with the fixed portion, a limit portion connected with the connecting portion, and a locking portion connected with the limit portion. The lamp bracket body has a first side provided with a first function portion and a second side provided with a second function portion. In assembly, the locking hook is mounted on the first function portion, and the limit locking plate is mounted on the second function portion.

A light fixture includes a housing having an upper wall, a first side wall, and a second side wall at least partially defining an interior and a bottom opening. A mounting tray is positioned in the interior and releasably connected to the housing. A first light emitter is connected to the mounting tray and has a first light output. A second light emitter is connected to the mounting tray and has a second light output. A third light emitter is connected to the mounting tray and has a third light output. A lens is connected to the housing. The light fixture can be optionally connected to a secondary light fixture and used to control light outputs from both fixtures.

A light troffer assembly has a cover panel. A T-bar frame has a right T-bar parallel to a left T-bar, and with a rear T-bar parallel to a front T-bar. A bracket frame is mounted between the cover panel and the T-bar frame. The bracket frame includes a first mounting bracket mounted above the right T-bar, a second mounting bracket mounted above the left T-bar, and a first mounting rail and a second mounting rail connecting the first mounting bracket to the second mounting bracket. The mounting bracket frame is sandwiched between the cover panel and the T-bar frame. An LED panel has an LED panel power supply, pivot hook latches and pivot pins.

A light emitting diode (LED) flat panel lighting fixture is provided. The LED flat panel lighting fixture comprises an LED flat panel lighting device comprising (a) one or more LEDs and (b) one or more first mating mechanisms. The LED flat panel lighting fixture further comprises a mounting bracket comprising one or more second mating mechanisms configured to each mate with a corresponding one of the one or more first mating mechanisms when the LED flat panel lighting device is rotated within the mounting bracket and with respect to the mounting bracket. The rotation of the LED flat panel lighting device within a plane of the mounting bracket and with respect to the mounting bracket causes the mating of the one or more second mating mechanisms with the corresponding ones of the one or more first mating mechanisms.

The T-bar includes an elongate rigid spine extending between terminal ends including either a fixed anchor or adjustable anchor for attachment to adjacent T-bars or other supports. An upper heat sink is provided on an upper portion of the spine to enhance heat transfer from the T-bar to air surrounding upper portions of the T-bar. A light housing is provided on a lower portion of the T-bar which is configured to support a lighting module therein, such as a light emitting diode (LED) light. A lower heat sink is provided above this light housing and integrated into a rest shelf which supports ceiling tiles adjacent the T-bar. A power supply is provided which can be removably attached to the T-bar and provide appropriately conditioned power for the lighting module.

A trough-shaped lamp housing (10) which is integrally produced in a deep-drawing process and has a housing bottom (11) and a housing wall (12) which laterally surrounds the housing bottom (11) and which, together with the housing bottom (11), delimits a lamp chamber, wherein the housing bottom (11) has a planar region (20, 25) for receiving at least one lamp component (120, 130) in a planar manner, wherein the planar region (20, 25) is circumferentially surrounded by a raised and/or recessed annular structure (35) which is integrally formed in a deep-drawing process, and wherein the housing wall (12) discontinues at the circumferential edge thereof that faces away from the housing bottom (11) in a circumferentially closed edge portion (16), which lies in a plane.

A mounting bracket for flush mounting a lighting device is provided. The mounting bracket comprises: a first planar member and a second planar member, at least one of the first and second planar members having a center, and one or two transverse members disposed at opposite ends of at least one of the first and second planar members, wherein at least one of the first and second planar members includes two adjacent openings and a receiving member offset from the center of the at least one of the first and second planar members, the receiving member being positioned intermediate the two openings.

A ceiling lamp, including a chassis, a frame assembly and an assembling assembly; the chassis is provided with an abutting surface bonded to a ceiling, and the frame assembly is detachably connected to the chassis in a vertical direction by the assembling assembly; the assembling assembly includes a first assembling member and a second assembling member, one of the first assembling member and the second assembling member is arranged on the chassis, and the other assembling member is correspondingly arranged on the frame assembly; a snap-fit groove is arranged in a side surface parallel to the vertical direction of the snap-fit main body, the snap-fit member is slidably arranged on the sliding base and is capable of protruding out of the sliding base to extend into the snap-fit groove, and the elastic element supplies an elastic pushing force for the snap-fit member to extend into the snap-fit groove.

Mounting boxes for overhead beams, such as purlins, of a building are described. The mounting box may include a front side that is designed to attach to a lateral side of the beam, an upper portion bottom that may rest on the horizontal beam, and a lower portion bottom that may have or be connected to a lighting socket or other electrical device.
