A lighting arrangement includes a rail, an indirect lighting module for the provision of indirect lighting, and a coupling unit. The rail is designed for coupling-on or at least partially accommodating a lighting module or a lighting unit and comprises an inner region. Along the rail, a conductor device is provided at least for providing electrical energy for supplying the lighting module or the lighting unit. The coupling unit is coupled to the rail and is arranged to receive electrical energy from the conductor device and to supply the indirect lighting module with electrical energy. The rail comprises a web which is designed as a limit of the inner region. The rail comprises a passage-opening in the region of the web. A contacting section of the coupling unit is passed through the passage-opening in order to bring about an electrical coupling of the indirect lighting module to the coupling unit.

A lighting arrangement includes an assembly, a rail profile, and an adapter unit. The assembly is designed as a lighting module or lighting unit coupled to the assembly or accommodated by the assembly. The rail profile has a first region for accommodating the assembly and a second region, in which a conductor device for providing electrical energy is provided along the rail profile. The adapter unit is accommodated in the second region of the rail profile and is configured to be electrically coupled to the conductor device in the second region, to receive electrical energy from the conductor device and to provide electrical energy to the assembly for supplying the lighting module or the lighting unit. The adapter unit and the assembly are configured for electrical coupling so that the assembly displaces along a longitudinal direction of the rail profile relative to the adapter unit inserted into the second region.

The invention relates to a lighting-means carrier (5) for a strip-lighting luminaire, comprising: at least one lighting-means circuit board (30) having light-emitting diodes (33) that can be arranged thereon; and at least one heat sink (31) thermally connected to the lighting-means circuit board (30). In a central region, the lighting-means circuit board (30) is rigidly connected to the heat sink (31) in such a way that substantially no relative motion between the lighting-means circuit board (30) and the heat sink (31) is possible. In at least two further regions, the lighting-means circuit board (30) is connected to the heat sink (31) in a floating manner, the lighting-means circuit board (30) therefore being arranged on the heat sink (31) in such a way that the lighting-means circuit board can be moved in relation to the heat sink (31) outside of the central region. The invention further relates to a strip-lighting luminaire having at least one lighting-means carrier (5) according to the invention.

A lighting fixture is provided. The lighting fixture includes a fixture body including an elongated shape, a first end, and a second end. A body mount is disposed at a first end side of the fixture body. A light source is accommodated in the fixture body and configured to emit laser light. A power supply is accommodated in the fixture body and electrically connected to the light source. A light guide includes an entrance end and an exit end. The entrance end is optically connected to the light source. The light guide is configured to guide the laser light from the light source to the exit end. A lamp is disposed at a second end side of the fixture body and optically connected to the exit end of the light guide.

Disclosed is a grid lighting system having at least one housing segment with at least one lighting zone. At least one lighting module is selected from at least one track lighting module and/or at least one non-track lighting module. The at least one lighting zone extends along a first length dimension of the housing segment and including at least one first passage to receive the at least one track lighting module and/or non-track lighting module. The housing segment includes a first power supply segment to be coupled with a designated line voltage outlet to deliver line voltage power to the at least one lighting module in the at least one lighting zone. Each track lighting module includes a lighting subzone, with a second passage to receive one or more lighting submodules along a second length dimension. A second power supply segment is provided to couple with the first power supply segment to receive line power and to deliver low voltage to the one or more lighting submodules.

A luminaire with a tool-less assembly feature that enhances ease of installation and serviceability in the field. The luminaire's housing defines a compartment accessible via a window adjacent a pair of opposed shoulders. The luminaire further includes a lighting module dimensioned to be received and retained in the window in an interference fit with the shoulders. The lighting module may include an LED module/light guide plate and/or an LED refractor assembly/LED gear tray. A resilient member is supported on the housing in position to abut the lighting module and deflect during insertion of the lighting module through the window, and to at least partially resile to maintain the lighting module against the shoulders in an operative position on the housing. Further, the resilient member is positioned to deflect during removal and to resile to tilt or otherwise assist in ejecting the lighting module from the housing during tool-less disassembly.

Luminaire connector for a luminaire strip composed of at least two luminaire elements connected in series and arranged on or in a room ceiling with feed contacts (2) for feeding electrical potential from an electrical building supply network into the luminaire strip, having two electrical connection contacts (5) in such a way that a bulbar (6) electrically supplying the luminaire element assigned to it is connected to each connection contact (5), and with at least one receiving means (15) for a mechanical coupling part (15) bearing the luminaire elements against one another.

A linear luminaire includes a channel with a bottom and sidewalls that arise from opposite sides of the bottom. A printed circuit board (PCB) including a number of LED light engines is mounted in the channel, and may be mounted on stand-offs away from the bottom of the channel. A mounting bracket is connected to an underside of the channel bottom. The linear luminaire also includes a base that can serve as a raceway for wires and cable. The base also has a bottom and sidewalls, and attaches releasably to the channel by means of cooperating engaging structures on the mounting bracket of the channel and portions of the sidewalls of the base.

A track adapter has a mounting seat, an electrical supply column, an adjustment conductive portion, and an adjustment knob, and a drive mechanism. As to the track adapter and the driving power supply with the track adapter and the track light, the lamp holder of the track lamp can wrap the whole track, which is neat and beautiful, and solve the problem of difficult phase adjustment of adaptor in the prior art at the same time. The phase adjustment knob is shrunk and put on the top of the adaptor, which solves the adjustment problem and adapts to more occasions, so that the structural design of the track lamp is more flexible.

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.
