Figs. 6 to 9 show an alternative embodiment of the luminaire of this invention, where the way of construction of the pipe and cover and of the connecting piece between the modules varies, as will be explained below.

Detailed description of some embodiments

An exemplary embodiment is schematically illustrated in Fig. 5 for which the current distribution means comprise first F1, a few seconds F2 and a third current distribution means F3 connected to respective current sources (not shown), such as three phases of a three-phase network, among which are available the selection means S, which, at the request of a user and from a remote point, select one of the phases F1, F2 or F3, and supply the current alternating from it to an AC / DC converter 9 which converts it into direct current and is supplied to the LEDs L illustrated, and belonging to one or more of the lighting modules M1, M2.

In the event that such current distribution means F1, F2, F3 are the referred phases of a three-phase network, obviously the selection means S will supply the alternating current, in this case to the AC / DC converter, through the phase selected and neutral, and the conduction corresponding to the ground will also be properly connected. Such conduits corresponding to neutral and ground have not been illustrated in Fig. 5.

Although not illustrated in detail in the accompanying figures, for a preferred embodiment, the housing of the connecting piece houses the said AC / DC converter inside.

For another embodiment, instead of the AC / DC converter, the selection means S connects to one of the distribution means F1, F2, F3 directly with the LEDs (set of special LEDs with mains connection equipment) or through a transformer (not shown) also located inside the housing of the connecting piece 3.

Fig. 3 corresponds to an exemplary embodiment for which the luminaire comprises fourth means of current distribution F4 connected to a fourth source of current supply, and the connecting part comprising a BAT battery, advantageously located (despite which is not shown in the drawing) inside the housing defined by the connecting piece 3 (which will include an appropriate housing or configuration). Said BAT battery is powered through the aforementioned means of distribution of current F1, F2, F3, from the AC / DC converter and has an associated control circuit that checks through said fourth means of current distribution F4 that the The mains supply is in correct conditions and in case of a power failure it communicates the battery with at least a part of the LEDs of the M1 module or of the adjacent modules M1, M2,

The use of a battery and the provision of a fourth means of distribution of current F4 (or additional line) allow to guarantee a supply of sections of the luminaire in the case of failures in the ordinary three-phase network.

As illustrated in Fig. 2, the housing of the connecting piece 3 is formed by a base 3a and a cover 3b, which includes on its outer face fins or ribs useful as heat sinks generated by the heat different devices and electrical and electronic circuits housed inside the housing.

An exemplary embodiment is illustrated in Fig. 1 for which the luminaire comprises a single lighting module M1, with its corresponding channeling 1 and cover 2, as well as an end connection piece 4, to be coupled thereto at one end, as well as an end cap 5 to be coupled thereto at the other end.

The luminaire of Fig. 1 also comprises a flange 8 for fixing the lighting module M1 to the roof of a passenger compartment.

Both the end connection piece 4, at one end of the luminaire, and the end cap 5 are intended to be fixed, for an embodiment for which the luminaire comprises several lighting modules to two respective end modules by their corresponding ends that are not used to attach to another lighting module. For such an embodiment, the luminaire comprises a plurality of flanges 8 for fixing all the lighting modules to the ceiling of a passenger compartment.

As illustrated in Fig. 2, where the luminaire of the invention is shown formed by two lighting modules M1, M2, elongated and connected in series forming a row, each of the lighting modules M1, M2 comprises metal connectors t accessible from the outside. Although not illustrated in the attached figures, these connectors are connected with conductors of the current distribution means and advantageously also with conductors of data distribution means, all conductors running through the interior of the pipe 1 .

Each connection piece 3 comprises a first and a second group of metal connectors T, electrically connectable with each other through said selection means S, and arranged in the connection piece 3 and configured for connection with the metal connectors t of the Two lighting modules M1, M2 to connect to each other.

Instead of the aforementioned translucent cover, the luminaire can apply other light dissipation principles, known per se, such as the application of LEDs on a edge of a transparent or translucent plate distributing light by diffusion, or the like, since the invention is applied to a selective control of the LED light source and not specifically to the distribution of said light source.

For the exemplary embodiment illustrated by Fig. 2, the first lighting module M1 defines a step e1 at a first end, and the connecting piece 3 is configured to be arranged partly on the footprint e1h of step e1 and partly on the footprint e3h of a step e3 defined by the second illumination module M2 at a respective first end arranged at the end with respect to the first end of the first illumination module M1, both steps being e1, e3 and the connecting piece 3 configured to fix at the first ends with each other when the connecting piece 3 is arranged on the footprints e1h, e3h of the steps e1, e3, the projecting portion Cn of the connecting piece 3 fitting into the hole O of the second module M2.

In the exemplary embodiment of Fig. 2, the coupling configuration C1 of each step e1, e2, e3, e4 is located in a riser wall e1c, e2c, e3c, e4c, from which part of the connectors protrude metallic t of the respective lighting module M1, M2.

In fact, the coupling configuration C1 is formed, for each step e1, e2, e3, e4, by projections (four in the illustrated example) to fit into corresponding recesses belonging to each coupling configuration C2, each connector coinciding positionally t with each of said projections, and each metallic connector T with each of said recesses.

It can be seen in Fig. 2 that one of the riser walls e1c, e3c closes the channel 1 of the respective module M1, M2 by a first end, and that a second end of the channel 1 of each module M1, M2 is closed by one of the riser walls e2c, e4c of the step defined at the second end of the corresponding lighting module M1, M2.

In Fig. 6, corresponding to a second exemplary embodiment of the invention, one end of one of the modules is shown, appreciating that in this exemplary embodiment the pipe comprises a hollow profile 1, for example obtained by extrusion, with a configuration upper in "T" 1a, to facilitate the suspension of the channeling of a ceiling by means of clamps, the cover 2 being defined, by a plate with lateral fins that are inserted in a conjugated profile grooves. In the represented portion, the set 10 of terminals ta provided for coupling to the connecting piece and a terminal tb in earthing functions can be seen.

Fig. 7 illustrates the termination of a module by means of a cover 11, fixed by one or more screws 12 to the pipe 1, which cover 11 has a window through which the cited ta and tb terminals appear.

In Fig. 8 the connection between two modules M1 and M2, both drawn incompletely, is schematically observed, observing the connection piece 3, with its cover 3b, which in general houses a shims converter and phase selection means, according to structure that has already been explained in the previous embodiment

5 explained.

Finally, in Fig. 9 the face is shown the base 3a of said connecting piece 3, provided with connectors Ta, Tb, according to two rows, one for each of the modules, intended to be connected to terminals ta and tb illustrated in Figs. 6 and 7 that have just been described.
