The present description refers to lighting devices.
One or more embodiments may refer to the assembly of lighting devices to a false ceiling.
One or more embodiments may concern a fastening device for fastening lighting devices to a false ceiling.
A false ceiling is a building construction with a lightweight structure placed under the ceiling of a building, which results in a decrease in the useful height of the room concerned. The false ceiling may be made to meet aesthetic requirements and to form a covering with heat-insulating, sound-absorbing or fire-resistant material. The false ceiling may also be used to house one or more systems in the compartment created between the false ceiling and the ceiling. The most typical system housed in the false ceiling is a lighting system.
The most widespread false ceiling structure envisages the use of a grid-shaped metal structure comprising a plurality of inverted T-shaped profiles, which may be fastened to the ceiling of the building by means of suspension wires. A false ceiling generally comprises a plurality of (by way of non-limiting example, square-shaped) panels having edges that may rest on lower horizontal wings of the T-shaped profiles of the false ceiling structure.
One of the most widespread solutions for installing a lighting system in a false ceiling envisages the use of panel-shaped lighting fixtures that are inserted in place of the respective false ceiling panels and that exactly occupy the space of a false ceiling panel.
An alternative lighting system, which is of increasing interest in the market, may envisage the use of linear lighting devices that replace corresponding sections of T-shaped profiles. A solution of this type may allow better integration, from an aesthetic point of view, of the lighting system in the false ceiling structure, since the lighting devices do not replace the false ceiling panels. However, this solution may involve installation difficulties due to the fact that it may be necessary to remove sections of the false ceiling supporting structure for assembling the linear lighting devices.
In addition to assembly problems, another aspect to consider is the electrical connection of the lighting devices to the electrical network. When the lighting devices replace a part of the false ceiling structure (false ceiling panels or sections of the T-shaped profiles), the electrical connections may be made on the upper part of the false ceiling.
However, in cases where the lighting fixtures do not replace portions of the false ceiling structure, it may be necessary to provide holes in the false ceiling structure for passing the electrical power supply cables. This solution has the disadvantage of making the installation of the lighting devices complicated. As an alternative to the provision of holes, it may be necessary to install electrical connectors on the sides of the false ceiling structure for electrical connection of the lighting devices. This solution has the disadvantage of having a negative effect on the aesthetic appearance of the false ceiling.
One or more embodiments intend to contribute to overcoming the drawbacks outlined above.
More specifically, one or more embodiments aim to provide a fastening device for fastening lighting devices to a false ceiling structure, which may simplify both the mechanical fastening of the lighting devices to the false ceiling supporting structure and the electrical connection of the lighting device to the power supply.
According to one or more embodiments, these objects may be achieved by a device having the characteristics referred to in the following description.
In the drawings, like reference characters generally refer to the same parts throughout the different views.

With reference in particular to
One or more non-limiting embodiments may have one or more of the following advantages:
the mechanical fastening of the lighting devices to the supporting structure of the false ceiling and the electrical connection of the lighting devices may be carried out without replacing or modifying parts of the false ceiling structure, so that the installation is simpler and faster,
given the gap formed between the base wall and the longitudinal side walls, to allow the passage of the electrical connections of the lighting device, and given the horizontal portion of the L-shaped side walls configured to cover this gap, the electrical connection of the lighting devices may result in having no adverse effects on the appearance of the false ceiling and on the simplicity of installation of the device,
the side walls of the fastening devices may be produced or painted with a color similar to the color of the false ceiling, so that the fastening devices may be perfectly integrated with the aesthetic appearance of the false ceiling.
One or more non-limiting embodiments may, therefore, concern a fastening device (e.g. 1) for fastening lighting devices (e.g. 10) to T-shaped profiles (e.g. 41) of a false ceiling (e.g. 40) comprising:
a base wall (e.g. 2) on which the lighting device (e.g. 10) is fastenable, wherein the base wall (e.g. 2) has two longitudinal opposite sides (e.g. 20) and two transversal opposite sides (e.g. 21),

In one or more non-limiting embodiments of the fastening device, the longitudinal side walls (e.g. 3) have an L-shaped conformation comprising:
a vertical portion (e.g. 30) extending in a direction perpendicular to the base wall (e.g. 2), the vertical portion (e.g. 30) being adjacent to the spacer elements (e.g. 5), and
a horizontal portion (e.g. 31), extending in a direction parallel to the base wall (e.g. 2), wherein the horizontal portion (e.g. 31) covers the gap between the side wall (e.g. 3) and the base wall (e.g. 2) of the device (e.g. 1).
In one or more non-limiting embodiments of the fastening device, the spacer elements (e.g. 5) have an L-shaped conformation, in which a horizontal portion (e.g. 50) lies on the same plane as the base wall (e.g. 2) and a vertical portion (51) is adjacent to a respective side wall (e.g. 3).
In one or more non-limiting embodiments of the fastening device, the device may comprise two transversal side walls (e.g. 6) rigidly connected along the transversal sides (e.g. 21) of the base wall (e.g. 2).
In one or more non-limiting embodiments of the fastening device, the fastening elements (e.g. 4), during use, are supported by an upper surface (e.g. 8) of a horizontal wing (e.g. 9) of the T-shaped profile (e.g. 41) of the ceiling (e.g. 40).
In one or more non-limiting embodiments of the fastening device, the base wall (e.g. 2) and the longitudinal side walls (e.g. 3) enclose the lighting device (e.g. 10) which, during use, protrudes below the false ceiling (e.g. 40) beyond a distal edge of the wing (e.g. 9) of a T-shaped profile (e.g. 41) of the false ceiling (e.g. 40).
In one or more non-limiting embodiments of the fastening device, the side walls (e.g. 3) have a grooved portion (e.g. 32) to allow, during use, installation of the device at the intersection of two or more horizontal wings (e.g. 9) of the T-shaped profile (e.g. 41).
In one or more non-limiting embodiments of the fastening device, the horizontal portions (e.g. 31) of the longitudinal side walls (e.g. 3) provide, during use, in particular at the part facing the ceiling, a support for any additional optical elements, as well as a support surface for the lighting device (e.g. 10).
One or more non-limiting embodiments may concern a system for fastening lighting devices (e.g. 10) to T-shaped profiles (e.g. 41) of a false ceiling (e.g. 40), comprising at least one fastening device (e.g. 1) according to one or more of the previous claims.
