The invention relates to a method for forming a luminaire (1), which has a trough-shaped luminaire housing (10, 110) having a region (25, 125) for accommodating illuminants, which is surrounded by a seal (40), a cover (70, 80) which spans the region (25, 125) and abuts the seal (40) in a peripherally closed manner, a frame-like holding element (50, 150), which presses the cover (70, 80) into abutment with the seal (40). For the luminaire housing (10 110), the cover (70, 80) and the holding element (50, 150), are each available in at least two different variants, which can be combined in any way, wherein in order to form the luminaire (1) according to desired output properties and/or properties with regard to heat dissipation or moisture resistance, a suitable luminaire housing (10, 110), a cover (70, 80) and a holding element (50, 150) are in each case selected and the selected components are assembled to form the luminaire (1).

An improved dimming apparatus is disclosed. Major economies are achieved by the ability to distribute groups of dimmers in proximity to the lamp loads that they control. Variations in the location and distance between the apparatus and lamp loads, as well as in the differing connector types installed on such loads, are addressed by terminating the six power stages contained in a common enclosure in a six-circuit multi-pole connector, such that a variety of prior art “break-out” adaptors between said multi-pole connector and individual circuit connectors can be selected among. The power input to the enclosure can be made re-configurable.

Technologies are described for an LED ceiling frame light configured to be mounted with a ceiling support grid. The LED ceiling frame light has a rectangular or square configuration with outwardly extending flanges configured and disposed to lay on inwardly extending flanges on the ceiling support grid. At least two connectors are configured and disposed to removably connect legs, or portions of the LED ceiling frame light, together and form the LED ceiling frame light into a rectangular or square shape with a rectangular or square opening.

A structural light fixture for the ceiling of clean room, such as a clean room for pharmaceutical or electronic research or production, includes an outer U-shaped beam and an inner U-shaped beam. The inner U-shaped beam nests within the outer U-shaped beam. The inner and outer U-shaped beams are mutually reinforcing so that the combination of the two U-shaped beams is stronger and stiffer than either U-shaped beam alone. The top side of the outer U-shaped beam is exposed to the outside of the clean room and includes no perforations so that the outer U-shaped beam is a barrier to gas, particulates, microorganisms or disinfectants that otherwise would pass through the clean room ceiling. The removable inner U-shaped beam includes a lamp and power supply, allowing maintenance of the structural light fixture from the interior of the clean room without interrupting the barrier to contamination created by the structural light fixture.

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.

An optical member includes a curved portion comprising an optically transmissive material. The enclosure has an outer surface and an inner surface opposite the outer surface. At least one light redirection feature protrudes from the inner surface. At least one indentation defined on the outer surface is configured to refract light.

A lighting system is disclosed herein. The lighting system can include light module for surface, recessed or pendant mounting. The module can include a channel having side walls and an open top and can extend between first and second ends. The module can also include an array of light emitting diodes disposed in the channel and a driver for controlling the light emitting diodes. The module can also include a lens mountable in the open top and a cap selectively engageable with at least one of the first and second ends. The cap can be removed from one of the ends when the module is interconnected with a second light module. The system can also include any one or more of a linking bracket, a positioning bracket assembly, tools for assembling the lens to the channel, and a control module.

A frame structure for ceiling lighting device is provided, which includes a plurality of first frame bars, a plurality of second frame bars and a plurality of corner braces. Each first frame bar includes a first frame bar body and a first chamber structure disposed on one side of the first frame bar body. Each second frame bar includes a second frame bar body and a second chamber structure disposed on one side of the second frame bar body. Each corner brace includes a first extension arm inserted into an opening at one end of the first chamber structure of one of the first frame bars and a second extension arm inserted into the opening at one end of the second chamber structure of one of the second frame bars, such that the first frame bars and the second frame bars can be combined with each other.

This disclosure relates to an assembly that is configured to be installed or integrated into a suspended grid ceiling.

The present invention provides a lamp and a lamp mounting structure, wherein the lamp includes a lamp panel as a light source; two lateral supports arranged opposite to each other, wherein the lamp panel in use is fixed to a lamp supporting structure through the two lateral supports; and a locking mechanism for securing the lamp panel between the two lateral supports. The lamp disclosed herein has a better versatility.
