Abstract:
A lighting device includes an elongated profiled body including at least one light permeable material, e.g. a polymeric material, having a mouth portion where an e.g. white light radiation source assembly is arranged which includes one or more electrically powered light radiation sources facing the profiled body. The light radiation emitted by the light radiation source assembly propagates through the light permeable material of the profiled body. The material of the profiled body includes pigments and is at least in part light diffusive, whereby, by propagating through profiled body, the light radiation becomes a colored light radiation of a color determined by the pigments and with a homogeneous near field distribution.
Abstract:
A lighting device may be produced by providing a protected elongate light emitting module, including a substrate with at least one electrically-powered light radiation source, and at least one sealing mass protecting light radiation source(s), and by coupling to said light emitting module a channel-shaped cover member with a body portion including light permeable material and side portions, with the side portions of the cover member embracing and locking therebetween the light emitting module and with light radiation source(s) facing towards body portion of cover member, whereby the light permeable material provides a propagation path for the light radiation from light radiation source(s).
Abstract:
A lighting device, such as for example a LED flexible module, includes an elongated profiled body having a mouth portion, a first and a second lateral sides arranged sidewise of the mouth portion and a web side opposed the mouth portion. The profiled body includes a light-permeable portion, extending between the mouth portion and the first lateral side, and a light-impermeable portion extending between the second lateral side and the web side. A light radiation source assembly including a support member with one or more electrically powered light radiation sources is arranged at the mouth portion with the light radiation source(s) facing the light-permeable portion, whereby light radiation is directed towards the first lateral side for emission from the lighting device.
Abstract:
A method of producing cut-to-length flexible electrical cords includes providing a flexible strip having a plurality of electrically conductive lines extending along the strip, arranging along said strip a plurality of electrical connectors including a plurality of tubular electrical conductors extending in a bridge-like manner between two subsequent portions of one of the conductive lines of said plurality, separating a portion of a given length from said flexible strip by cutting at least one said connector in a transverse plane, thus cutting the plurality of tubular electrical conductors in the cut connector, whereby said portion separated from said flexible strip forms a flexible electrical cord having, at one end at least, a plurality of electrical connection holes or sockets exposed as a result of the cutting of said tubular conductors.

Abstract:
A lighting device may include a light radiation source board carrying at least one electrically powered light radiation source, e.g. a LED source, and a frame-like housing having a window, the board of the light radiation source being arranged in the housing with the light radiation source facing window. A glass cover covering the window is inserted in the housing by sliding along the housing or by tilting against the housing.
Abstract:
A mounting device for mounting on a substrate a plate or board-like lighting source may include a frame member for surrounding the plate or board-like lighting source, anchoring formations for anchoring the frame member onto the substrate while permitting movement of the frame member towards and away from the substrate, elastic means for elastically urging the frame member towards the substrate, and one or more locking members mounted on the frame member and radially displaceable with respect to the frame member between: a radially outward position, in which the plate or board-like lighting source can be inserted into the frame member and positioned between the frame member and the substrate, and a radially inward position, in which the locking member(s) abuts/abut against the plate or board-like lighting source located between the frame member and the substrate, elastically urging the plate or board-like lighting source towards the substrate.
