The lighting system comprises a plurality of lighting modules (1) housed inside at least two profiles (10), said profiles (10) being coupled to each other by means of at least one coupling element (2), characterised in that the or each coupling element (2) comprises a plate (3) and fixations (4) for fixing the coupling element (2) to at least two adjacent profiles (10).

It enables the provision of a modular lighting system formed by a plurality of lighting modules coupled to each other, wherein the lighting is continuous throughout the system, without there being any interruption at the ends of the lighting modules.

Description

The present invention relates to a modular lighting system comprising a plurality of lighting modules coupled to each other.

Background of the invention

Modular lighting systems comprising a plurality of lighting modules, usually elongated, that are coupled to each other, both longitudinally and transversely, forming a desired layout, are well known.
The objective of these modular lighting systems is to minimise costs using lighting modules of a single type. To this end, the elongated lighting modules must be coupled by means of coupling elements disposed at their ends.
A drawback of the currently known modular lighting systems is that these coupling elements block the light in their mounted position, such that the lighting is not continuous throughout the lighting system, but rather is interrupted at the ends of each lighting module.
This drawback prevents the provision of the desired lighting and, also, is not aesthetically pleasing to users.
Also, the electrical connections between the modules are usually executed using terminal strips, which slows down installation, as the electrical connection between each module is executed individually and manually.
Therefore, the objective of the present invention is to provide a modular lighting system formed by a plurality of lighting modules coupled to each other, wherein lighting is continuous throughout the system, without there being any interruption at the ends of the lighting modules.

Description of the invention

The lighting system of the invention resolves the aforementioned drawbacks and has other advantages which are described below.
The lighting system in accordance with the present invention comprises a plurality of lighting modules housed inside at least two profiles, said profiles being coupled to each other by means of at least one coupling element, and is characterised in that the or each coupling element comprises a plate and fixations for fixing the coupling element to at least two adjacent profiles.
Due to this characteristic, the plate does not block the light emitted in the desired direction of lighting and the rest of the coupling element is substantially free from obstacles.
In accordance with two possible additional embodiments, depending on the number of lighting modules coupled, said coupling element comprises a lateral plate fixed to the end of two adjacent profiles, or said coupling element comprises two lateral plates joined together perpendicularly, also joined to two adjacent profiles.
In accordance with a preferred embodiment, said fixations are disposed on projections substantially perpendicular to said plate.
Also, said projections may be formed by two strips forming a right angle and, on each projection, the fixations may be formed by two tabs that form a right angle, said tabs being disposed on the vertex formed by said two strips.
Also advantageously, each lighting module comprises a rotary electrical connector next to each of its ends, each rotary electrical connector comprising a plurality of electrical connection projections. This rotary electrical connector makes it possible to use the same lighting module in the event of coupling the lighting modules longitudinally (one after another) or transversely (forming a right angle).
Additionally, the use of a link connector that connects two rotary connectors of two adjacent lighting modules is also envisaged, said link connector comprising terminals.

Description of a preferred embodiment

The lighting system in accordance with the present invention comprises a plurality of lighting modules 1 coupled to each other and housed in one or more profiles 10. One or more lighting modules 1 can be housed inside a single profile 10 and the profiles 10 are made of an appropriate material to allow light to pass through.
In the present description and in the claims, "lighting module" is understood to be a body having light-emitting elements and a screen which allows light to pass through in the desired direction, wherein the lighting module is elongated. All the lighting modules of a lighting system in accordance with the present invention are preferably of the same length, although they may be of different lengths.
The profiles 10 may be joined together by means of coupling elements 2, which may be of three different types depending on the number of profiles 10 coupled to each other, as shown in figures 1 to 3.
However, all the coupling elements 2 include common characteristics that provide the technical advantage, which is the objective of the present invention, to provide continuous, uninterrupted lighting, as indicated previously.
Each coupling element 2 comprises a plate 3 and fixations 4 for fixing the coupling element 2 to at least two adjacent profiles 10. This basic embodiment of the coupling element 2 is shown in figure 1, for the coupling of four profiles 10 forming a cross-junction.
It should be understood that, when reference is made to the plate 3, this plate may be disposed in an upper, lateral or lower position depending on where the lighting system of the present invention is installed, such that this plate only blocks the light in a direction one does not wish to illuminate. Therefore, when the plate is disposed in an upper position, the lighting system will be mounted on the ceiling or near the ceiling; when it is disposed in a lateral position, the lighting system will be mounted on a wall; and when the plate is disposed in a lower position, the lighting system will be mounted on the floor, with the plate blocking the light towards the ceiling, wall or floor, respectively.
In accordance with the embodiment represented, said fixations 4 are disposed on projections 6 substantially perpendicular with respect to said plate 3. Additionally, in this embodiment, said projections are formed by two strips that form a right angle and in each projection 6 the fixations 4 may be formed by two tabs that form a right angle, wherein said tabs are disposed on the vertex formed by said two strips.
The tabs may be joined to each lighting module in any appropriate manner. For example, each strip may comprise a hole for inserting a nail or screw, or similar.
Figure 2 shows the coupling element 2 used to couple three profiles 10 to each other, forming a T-junction. In this embodiment, as opposed to the coupling element 2 of figure 1, it comprises a lateral plate 5 fixed to the ends of two adjacent profiles 10.
Figure 3 shows a coupling element 2 used to couple two profiles 10 to each other, forming a right-angle junction. In this embodiment, as opposed to the coupling element 2 of figure 1, it comprises two lateral plates 5 joined together forming a right angle, each of which is fixed to one end of said profiles 10. It should be noted that one of these lateral plates is not shown in figure 2, since it is on the rear side.
In order to use the same lighting module in the event of coupling the lighting modules longitudinally (one after the other) or transversely (forming a right angle), each lighting module 1 comprises a rotary connector 7 next to each of its ends, wherein each rotary electrical connector 7 comprises a plurality of electrical connection projections 8, as can be observed in figure 4.
It should be noted that figure 4 shows two lighting modules 1 to be connected one after the other. In the event that the lighting modules 1 are connected forming a right angle, the rotary connector 7 of each lighting module 1 will rotate 90 degrees.
In order to connect two lighting modules 1 to each other, a link connector 9 is used, having terminals 11 which enable the connection of more lighting modules 1 or the selection of lighting modules 1 that light up simultaneously in accordance with the electrical connections executed.
In figure 5, which shows a lighting system in accordance with the present invention from below, i.e. as a user would see it, it can be observed that the coupling elements do not block the light and the user cannot see any coupling element, as they are hidden.
This characteristic has technical advantages, as it does not affect the desired lighting and aesthetics, as mentioned earlier.
Despite the fact that reference has been made to a specific embodiment of the invention, it is evident for the person skilled in the art that numerous variations and changes may be made to the lighting system described, and that all the aforementioned details may be substituted by other technically equivalent ones, without detracting from the scope of protection defined by the attached claims.
