Lighting system

A lighting system (1) comprising a flat support cable (2) with a substantially rectangular cross-section, having two conductive wires (13) only, arranged longitudinally parallel to each other and covered by a covering sheath (14) which envelops the conductive wires (13) with a filler material (15) positioned between the conductive wires (13) and the sheath (14);

• a plurality of fastening elements (3) for supporting the cable (2) along a path;
• a plurality of coupling elements (4) fixable to the cable (2) and having respective pairs of contacts (44) which draw current from the cable (2);
• and a plurality of lighting devices (5) coupled to respective coupling elements (4);
• coupling element (4) being provided with a printed circuit board (50), connected to the contacts (44) and to the lighting device (5) coupled to the coupling element (4);
• the system (1) being characterized in that the board (50) comprises a DC converter (51);
• a dimmer (52);
• and a Bluetooth module (53) for receiving and processing signals from an external control device;
• the board (50) being configured to receive a direct current from the cable (2) at an input voltage, via the two pairs of contacts (44), and to generate a dimmed direct current at an output voltage, different from the input voltage, which supplies the lighting device (5) connected to the board (50);
• and wherein each coupling element (4) comprises a casing (40) provided with a guide (42) which extends along an axis (B) and receives the cable (2);
• and wherein the guide (42) has a bottom wall (47) which supports the cable (2), and a pair of clips (43), located at respective longitudinal ends of the coupling element (4) and aligned with each other and projecting from the bottom wall (47) to engage the cable (2) and provided with respective electric contacts (44) for contacting the cable (2);
• each clip (43) being formed by two opposite facing arms (45, 46), which can be separated or opened for inserting the cable (2) and the cable (2) being clamped between respective opposite arms (45, 46) of each clip (43), which clamp the cable (2) in the guide (42) locking the coupling element (4) with respect to the cable (2) and also causes the contacts (44) to penetrate the cable (2), perforating the sheath (14) and the filler material (15) in order to contact the conductive wires (13);
• and wherein the contacts (44) are arranged offset relative to each other perpendicularly to the bottom wall (47) of the guide (42), being placed at different distances from the bottom wall (47).
