Abstract

A fastening device for fastening lighting devices to T-shaped profiles of a false ceiling comprises a base wall on which the lighting device may be fastened. The fastening device also comprises two longitudinal side walls rigidly connected along the longitudinal sides of the base wall and a plurality of fastening elements arranged along the longitudinal sides of the base wall, wherein the fastening elements can be folded in the direction of the base wall, to engage the fastening device with the T-shaped profile. The fastening device also comprises at least two spacer elements arranged between the base wall and a respective longitudinal side wall to provide a gap between the side walls and the base wall. This gap provides a passage for the electrical connections between the lighting device and a power supply source located above the false ceiling.

First claim

What is claimed is:

1. A fastening device for fastening one or more lighting devices to T-shaped profiles of a false ceiling, comprising:
a base wall on which the one or more lighting devices are fastenable, wherein the base wall has two longitudinal opposite sides and two transversal opposite sides,
two longitudinal side walls rigidly connected along the longitudinal sides of the base wall,
a plurality of fastening elements provided along the longitudinal sides of the base wall, wherein the fastening elements are foldable in a direction of the base wall, for engaging the fastening device with the T-shaped profile,
at least two spacer elements each located along a portion of a respective longitudinal side of the base wall, each spacer element arranged between the base wall and a respective side wall to provide a gap between the respective side wall and the base wall, wherein the gap provides a passage for one or more electrical connections between the one or more lighting devices and a power supply source located above the false ceiling.

2. A fastening device according to claim 1 , wherein the longitudinal side walls have an L-shaped conformation comprising:
a vertical portion extending in a direction perpendicular to the base wall, wherein the vertical portion is adjacent to the spacer elements, and
a horizontal portion, extending in a direction parallel to the base wall, wherein the horizontal portion covers the gap between the respective side wall and the base wall of the device.

3. A fastening device according to claim 1 , wherein the spacer elements have an L-shaped conformation, wherein a horizontal portion lies on the same plane of the base wall and a vertical portion is adjacent to a respective side wall of the device.

4. A fastening device according to claim 1 , wherein the fastening elements are supported on an upper surface of a horizontal wing of the T-shaped profile of the false ceiling.

5. A fastening device according to claim 1 , wherein the base wall and the longitudinal side walls enclose the one or more lighting devices and protrude beneath the false ceiling beyond a distal edge of the wing of the T-shaped profile of the false ceiling.

6. A fastening device according to claim 1 , wherein the fastening device has two transversal side walls rigidly connected along the transversal sides of the base wall.

7. A fastening device according to claim 1 , wherein the side walls have a grooved portion for enabling installation of the device at an intersection of two or more horizontal wings of respective T-shaped profiles.

8. A fastening device according to claim 2 , wherein the horizontal portions provide a support for any additional optical elements, and a support plane for the one or more lighting devices.

9. A system for fastening one or more lighting devices to T-shaped profiles of a false ceiling, the system comprising at least one fastening device, the at least one fastening device comprising:
a base wall on which the one or more lighting devices are fastenable, wherein the base wall has two longitudinal opposite sides and two transversal opposite sides,
two longitudinal side walls rigidly connected along the longitudinal sides of the base wall,
a plurality of fastening elements provided along the longitudinal sides of the base wall, wherein the fastening elements are foldable in a direction of the base wall, for engaging the fastening device with the T-shaped profile,
at least two spacer elements each located along a portion of a respective longitudinal side of the base wall, each spacer element arranged between the base wall and a respective side wall to provide a gap between the respective side wall and the base wall, wherein the gap provides a passage for one or more electrical connections between the one or more lighting devices and a power supply source located above the false ceiling.

10. A fastening device according to claim 8 , wherein the support is provided at a part facing the ceiling.
