A lighting system has at least one luminaire having a connection portion, and has a fastening device, with a housing; an electrical contact-making connection, which can be detachably inserted into a supply connection of the luminaire, which supply connection is formed in the connection portion; at least one retaining pin, which has a securing portion, wherein the retaining pin, in a fitted state of the fastening device, extends through a slot formed in the connection portion of the luminaire, and the securing portion of the retaining pin is engaged behind a region of the connection portion that defines the slot; and a fastening portion for fastening a retaining cord and/or for connecting the terminals of an electrical supply cable.

Adjustable lamp for illuminating a setting which comprises at least two load-bearing electrically-conductive electric cables, an illuminating body extended with main extension along a longitudinal axis, supported suspended by the load-bearing electric cables and comprising an illumination source, first and second electrical connection elements mechanically associated with the illuminating body at at least two sections thereof spaced from each other, respectively electrically connected to the two load-bearing cables in order to electrically power the adjustable lamp.

Disclosed is a quick connection device, which includes an upper cover and a lamp, the upper cover comprises an upper cover body and an upper cover covering edge integrally formed with the upper cover body, the upper cover covering edge is positioned at an outer side of the upper cover body, and a clamping groove is provided at an inner wall of the upper cover body; the lamp comprises a lower cover connected to the upper cover, the lower cover comprises a lower cover body and a lower cover covering edge integrally formed with the lower cover body, the lower cover covering edge is positioned at an outer side of the lower cover body, a clamping block is arranged on an outer wall of the lower cover body, and the lower cover body is clamped in the clamping groove of the upper cover body through the clamping block.

A modular acoustic baffle fixture comprising a plurality of acoustic sound absorbing panels forming at least part of the structure of the fixture in which the acoustic sound absorbing panels are mechanically and releasably affixed to an internal support structure and which absorbs sound directed to the void formed therewithin. An LED panel and LED driver may be provided and retained by an internal support structure to project light from the fixture.

A system and method are provided for levelling suspended luminaires. The system includes a shuttle and a thumb wheel disposed in a housing. The shuttle includes a gripper for securing the cable wires that attach to the luminaire. A rotational movement of the thumb wheel is translated to linear movement of the shuttle within a slot of the housing to allow adjustment of an attachment point of the cable wire relative to the rest of the luminaire to enable tool-free levelling of the luminaire.

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.

An example joiner system for joining a first section and a second section of a fixture includes a joiner bracket that has formed therein a depressed ramp region. A joiner fastener, such as a screw, may engage against the angled walls of the joiner bracket ramp, to translate the vertical movement of the screw into a horizontal, longitudinal movement of the joiner bracket. The joiner bracket may be rigidly coupled to one section of a light fixture assembly, such that engaging the screw ramp with a fastener that extends through another section of the light fixture causes the two fixture sections to move toward each other. As vertical movement of a fastener produces horizontal movement of the joiner bracket, the joiner fastener or set screw may extend outside of the light fixture assembly, so as to be readily accessible by a technician.

Apparatus and methods for deployment of fixtures. The apparatus may include a system for controlling deployed fixtures. The system may receive user commands different devices in different formats. The fixtures may be independently addressable. The fixtures may be magnetically supported by a fixture support. A brace may join two or more fixture supports without reducing space available to support fixtures. The brace may join a fixture support to a fixture support accessory. An accessory may include a variable-angle junction. The fixture may include articulating joints for controlling the direction of a beam. The fixture may include a lens having an electrically controllable beam spread angle. The fixture may be stowable in the fixture support. The fixture may be slidable along a cord to adjust a height of the fixture. The fixture may include an extendable ring. The system may coordinate motions of the fixtures to follow a target. The fixture may include an elongated board. The elongated board may include a non-polar power socket.
