A lighting assembly connector is configured for being inserted into a lighting track. The lighting assembly connector includes a casing having a width defining a lateral direction and a length defining longitudinal direction. The length is greater than or equal to the width. The casing is definable as including three sections each defining one-third of the length. The three sections include a middle section, a first end section including a first longitudinal end of the casing and a second end section including a second longitudinal end of the casing. The middle section has a greater average width than each of the first end section and the second end section. The lighting assembly connector also includes a plurality of electrical contacts extending out of the casing each configured for contacting a respective line of the lighting track; and at least one fastener connected to the casing configured for removably connecting the lighting assembly connector to the lighting track.

A lighting system comprising a track having a first and a second rail, mutually extending equidistantly. Said first and second rail comprise a first respectively a second electrically conductive strip, mutually electrically isolated. A lighting module comprising a first and second electrical contact, which lighting module in mounted position rests by gravitational force on the first and second rail. When mounted the first and second electrical contact are in electrical contact with a respective one of the first and second electrically conductive strip. The lighting module is dismountable from the track by a single displacement of the lighting module in a direction against the direction of the gravitational force.

A modular lighting system comprises at least one module comprising a rail elongated longitudinally along an axis where one or more lighting elements are placed and mounted reversibly onto the rail by magnetic coupling, drawing power from a printed circuit board on the rail by means of spring contacts.

A lighting device is disclosed that includes one or more master circuit boards configured to power light emitting diodes. The lighting device also includes modular light boards with arrays of light emitting diodes that interchangeably couple to the matched connectors on the master circuit board. The master circuit boards and the modular light boards are positioned within a housing with one or elongated diffuser lenses covering or embedding rows of light emitting diodes on the modular light boards. In accordance with the embodiments of the invention, master circuit boards and modular light boards are mounted in a stacked arrangement to emit light from opposed sides of the housing. In further embodiments of the invention, the lighting device includes a controller for independently controlling light output from each master circuit board.

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 present invention relates to an adapter (1) for connecting a light to a track having mains phases and comprising a housing (2), at least one spring-loaded connector (6.1) linked to the housing (2), and a cover (4) partially covering the housing (2) and having at least one opening (8.1). The cover (4) is displaceable so as to be placed selectively in one of: a position in which the at least one spring-loaded connector (6.1) extends at least partially through the at least one opening (8.1), a position in which the cover (4) covers the at least one spring-loaded connector (6.1).

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.
