Fastening device and a system for fastening lighting devices to a false ceiling

1. A fastening device for fastening lighting devices to T-shaped profiles of a false ceiling, comprising:

a shaped flat body of electrically insulating material in which there are embedded conductive tracks having first and second ends that protrude from opposite ends of said flat body, wherein said conductive tracks are configured for establishing an electrical connection between a lighting device and a power supply source located above the false ceiling; and

a connecting portion configured to protrude beneath the false ceiling beyond a distal edge of a wing of a T-shaped profile of the false ceiling; wherein the connecting portion comprises an engagement formation configured to engage a complementary engagement formation formed on one side of a lighting device.

2. A device according to claim 1 , comprising a supporting portion configured to rest on an upper surface of a horizontal wing of a T-shaped profile of the false ceiling.

3. A device according to claim 1 , wherein said second ends of said conductive tracks protrude from said connecting portion.

4. A device according to claim 1 , comprising a terminal portion; wherein said first ends of said conductive tracks protrude from the terminal portion.

5. A device according to claim 4 , comprising a diverted portion laterally displaced with respect to a head of a T-shaped profile of the false ceiling.

6. A system for fastening lighting devices to T-shaped profiles of the false ceiling comprising at least one fastening device according to claim 1 .

7. A system according to claim 6 , comprising a first fastening device and a second fastening device arranged on opposite sides of a T-shaped profile.

8. A system according to claim 7 , wherein said first fastening device and second fastening device are offset from each other along a direction parallel to a longitudinal axis of a respective T-shaped profile.

9. A system according to claim 7 , comprising a first fastening device provided with conductive tracks and a second fastening device without conductive tracks, arranged opposite each other on opposite sides of a T-shaped profile and fastened to each other by snap-engagement formations.

10. A fastening device for fastening lighting devices to T-shaped profiles of a false ceiling, comprising:

a shaped flat body of electrically insulating material in which there are embedded conductive tracks having first and second ends that protrude from opposite ends of said flat body, wherein said conductive tracks are configured for establishing an electrical connection between a lighting device and a power supply source located above the false ceiling;

a terminal portion; wherein said first ends of said conductive tracks protrude from the terminal portion; and

a diverted portion laterally displaced with respect to a head of a T-shaped profile of the false ceiling.

11. A system for fastening lighting devices to T-shaped profiles of a false ceiling comprising:

a first fastening device comprising a shaped flat body of electrically insulating material in which there are embedded conductive tracks having first and second ends that protrude from opposite ends of said flat body, wherein said conductive tracks are configured for establishing an electrical connection between a lighting device and a power supply source located above the false ceiling; wherein the first fastening device comprises conductive tracks; and

a second fastening device arranged on opposite sides of the T-shaped profile; wherein the second fastening device is without conductive tracks; and wherein the first fastening device and the second fastening device are fastened to each other by snap-engagement formations.
