The invention relates to lightweight LED lighting systems for permanent and semi-permanent mounting on elevated structures, the lighting systems having integrated support and thermal transfer features. The systems are particularly suited for elevated mast systems and specifically for mast systems that are repeatedly lifted and lowered such as drilling and service rig masts. Specifically, the invention improves a) the weight/lumen ratios of LED lamp assemblies and LED lighting systems, b) the net added weight of LED lighting systems, c) the footprint of LED light systems and/or d) obviates the need for removing LED lighting systems or their sub-assemblies when transporting mast systems.

An air frame system includes a frame body defining one or more openings, a plurality of air passages along an inner periphery of the one or more openings, and an airframe grid coupled to the frame body. The airframe grid includes at least one wireway channel therein and a wireway channel cover clip is removably coupled to the at least one wireway channel. The air frame system also includes a light assembly removably coupled to the airframe grid, and a retainer clip removably coupled to the airframe grid. The airframe grid retains the light assembly within the airframe grid.

A panel lamp includes a bottom case, a lamp cover, a lighting assembly arranged between the bottom case and the lamp cover, at least two bendable suspending assemblies arranged at two opposite sides of the bottom case. The bottom case defines a mounting groove, and an edge of the lamp cover is configured to be received into the mounting groove. The suspending assemblies are configured to hang the bottom case onto an overhead structure.

A lighting system is disclosed which provides dynamic lighting control of each light on a rail lighting system. The lighting system is able to change settings of each light within a track lighting or rail lighting system based on motion, user preferences, lighting conditions, or security parameters. Light intensity and color can be set and scheduled based on user control and programming. Optical sensors may also be used to provide control input for the track lighting or rail lighting.

A modular fixture may include an LED light board and an LED driver positioned along a linear support structure, and includes at least two acoustic panels. The fixture further includes two-piece fasteners, some of which are positioned along the linear support structure, while others are positioned on an inward-facing surface of the acoustic panels. The two-piece fasteners are then able to removably secure the acoustic panels to the linear support structure.

A lighted tile for false panel, including a frame having a bottom and sides that extend projecting from the bottom, a backlighting system having a series of lights attached to the bottom, and a stretched flexible sheet that extends between the sides facing the lights. The lights are light-emitting diodes, and the sheet is secured to the sides of the frame.

A driving device according to an embodiment includes a supporting portion, an arm portion and a reinforced portion. The supporting portion includes an electrically-driven first drive source. The arm portion is supported by the supporting portion at one end portion in an extending direction and is, by the first drive source, rotatable about a first rotation axis that is along the extending direction, the arm portion including an electrically-driven second drive source. The reinforced portion is provided inside the arm portion and reinforces the arm portion. An object of operation is mounted on another end portion side of the arm portion and is rotatable about a second rotation axis intersecting the extending direction by the second drive source.

LED lighting systems and methods for retro-fitting existing lighting systems such as acorn and other globe style fixtures is disclosed. The retro-fit systems can be provided with an LED driver, an adaptor casting which mounts to industry standard fixture, a riser for adjusting the height of the lighting fixture, and an assembly of an optically active sealing lens, a heat sink and a LED board, wherein the LED lights, which can be made up of a plurality of LEDs, are arranged in concentric rings on the LED board, and are fitted with a sealing lens in the form of a rotated bubble optic with concentric grooves on the inner surface.

An LED ceiling lamp includes a base, a lampshade, an LED component, and a power supply assembly. The base includes a main body and a receiving box having an opening, the main body defines a through hole, an opening end of the receiving box disposes on an edge of the through hole on the main body. The lampshade is shielded on the base, the receiving box is received in a cavity enclosed by the lampshade and the base. The LED component is disposed on the base and received in the cavity. The power supply assembly is received in the receiving box and located outside the cavity, the receiving box defines a wire hole, the power supply assembly has a wire, the wire extends through the wire hole, the power supply assembly is electrically connected to the LED component through the wire.

Area lighting with a luminaire constructed from an array of light-emitting diodes (LEDs) distributed along the convex surface segment of an elliptic torus provides a uniform light output to the surrounding area.
