Abstract:
A device for mounting lighting sources on a substrate includes a channel-like mounting frame provided with fixing formations for fixing on said substrate, said mounting frame defining a cavity for receiving said lighting source with said lighting source resting on said substrate, a slider member which can be positioned in said cavity of said mounting frame to urge said lighting source toward said substrate; said slider member being slidable with respect to said mounting frame between an insertion position and a locking position, wherein said mounting frame and said slider member bear complementary engagement formations cooperating in a ramp-like manner to force said slider member and the lighting source urged thereby toward said substrate when said slider member is advanced from said insertion position toward said locking position.
Abstract:
A lighting device may include a channel-shaped elongated profiled body including a light permeable material and having a mouth portion, and a light radiation source assembly arranged at the mouth portion and including a support board having one or more electrically powered light radiation sources, e.g. LED light radiation sources, thereon facing profiled body. Mouth portion of profiled body includes shoulder formations arranged sidewise of said mouth portion, with support board abutting against said shoulder formations.
Abstract:
A lighting device includes an elongated profiled body with a web wall having first and second opposing faces, and two side walls to the side of the web wall, the latter having longitudinal slots extending therealong. In the profiled body, there may be provided an elongated light radiation source module including a support board with electrically conductive formations facing said longitudinal slots and at least one electrically-powered light radiation source which is in electrical contact with said electrically conductive formations. The light radiation source module is locatable in elongated profiled body extending between both side walls, with support board facing towards the first face of web wall. An electrical contact slider member slidable along the second face of web wall is provided with electrical contact pins adapted to extend into said longitudinal slots. Slider member is displaceable towards support board with pins contacting said electrically conductive formations of support board.
Abstract:
In various embodiments, a connector for lighting devices including an elongate planar support member having a front surface with electrically conductive lines and at least one electrically-powered light radiation source thereon, is provided. The connector includes a C-shaped body having a web portion and two side portions, said C-shaped body locatable astride said planar support member with said web portion facing said front surface, and electrical contact means extending from said web portion between said side portions configured to contact electrically conductive lines on said front surface of said planar support member.

Abstract:
A light fixture may include a plurality of elongate members, each extending between opposed ends and carrying one or more light radiation sources, such as LEDs, and at least one hinge member which mechanically couples one end of one of the elongate members to one end of another of the elongate members. Thus the hinge member allows the orientation of the elongate members between: an open position, wherein the elongate members extend in sequence with each other in a common direction, and a closed position, wherein the elongate members extend side by side.
Abstract:
A method for passing an electrical cable through a hole in a housing of a unit of electrical equipment is provided. The method may include: fitting onto the cable a tubular, mushroom-shaped male member comprising a stem with a threaded portion and a portion with enlarged head; inserting into the hole the cable having the male member fitted thereon extending through said hole with said portion with enlarged head abutting against the periphery of the hole externally to the housing and said threaded portion protruding inside the housing; and retaining said male member in the hole by coupling with said threaded portion that protrudes inside the housing an annular female member in the form of a nut co-operating with the periphery of the hole inside said housing to counter the movement of the female member with respect to the housing.
Abstract:
A fastening device for fastening lighting devices to T-shaped profiles of a false ceiling. The fastening device may include a shaped flat body of electrically insulating material having conductive tracks embedded therein. The conductive tracks may have first ends and second ends that protrude from opposite ends of the flat body. The conductive tracks may be configured for establishing an electrical connection between a lighting device and a power supply source located above the false ceiling.
Abstract:
A lighting module includes a base, at least one electrically powered light radiation source carried by said base, a plurality of lamina electrical contacts connected to said light radiation source, and having respective proximal ends fixed to said base and respective distal ends elastically pressed against one face of said base, wherein the distal ends of said lamina electrical contacts have respective mutually offset contact areas.
