- The features and advantages of the lighting system according to the invention will however become apparent from the following description of preferred embodiments thereof, given by way of indication and not by way of limitation, with reference to the accompanying drawings, wherein:

Figure 3 shows a cross-section of the bar alone; and -
Figure 4 shows a plan view of a portion of the linear electronic board and of the underlying power connector. - In said drawings, reference numeral 1 indicates a lighting system according to the invention as a whole.
- The lighting system 1 comprises a
lighting bar 10 and at least onelighting device 100; 100' couplable to the lighting bar, in any axial position along the lighting bar. - In the example of
Figure 1 , for example, aprojector 100 with adjustable optics and a downlight 100' with fixed optics are coupled to thelighting bar 10. Of course, other types of devices can be simultaneously connected to thelighting bar 10, according to the coupling methods described below. - The
lighting bar 10 comprises abar body 12 which extends longitudinally along a bar axis (X). For example, thebar body 12 is made with an extruded section bar, for example, of aluminum. - This
bar body 12 is suitable to be fixed to a support, for example a ceiling or a wall, even recessed or suspended. - The
bar body 12 comprises aninner portion 12a and anouter portion 12b. - The
inner portion 12a forms acentral seat 14 defining a longitudinalcentral opening 16. In other words, thecentral seat 14 is open along one side of theinner portion 12a, for example, a side opposite to the one for fixing it to the support. - The
outer portion 12b is coaxial to theinner portion 12a and forms, with the inner portion, twolongitudinal side pockets 122 which are open at least in the same direction as the longitudinalcentral opening 16. - The
lighting bar 10 comprises alinear lighting source 18 housed in thecentral seat 14. Thelinear lighting source 18 comprises a linearelectronic lighting board 20, or an elongated electronic board, or a stripshaped one, along the body axis (X). On the linear electronic board 20 alighting circuit 22 is obtained, suitable to generate a light beam, preferably substantially continuous, facing towards the longitudinalcentral opening 16 when it is electrically powered by a firstpower supply line 25 which extends along the linearelectronic board 20. - For example, the lighting circuit comprises a row of LEDs 22' mounted and uniformly distributed on the electronic board.
- According to the invention, the linear
electronic board 20 is embedded in aninsulating body 24 made of a translucent polymer material, for example a silicone material. - For example, the linear
electronic board 20 is co-molded with theinsulating body 24. In an alternative embodiment, theinsulating body 24 is crossed by a longitudinal seat and the linearelectronic board 20 is subsequently inserted in such longitudinal seat. - In any case, the
insulating body 24 with the linearelectronic board 20 gives the lighting bar 10 a degree of protection suitable for the use in outdoor environments, therefore resistant to atmospheric agents and dust. - A second electrical
power supply line 26 is obtained along the linearelectronic board 20, independent of the first one. - For example, the two
power supply lines electronic board 20. For example, such electrical conductors are in the form of tracks obtained on the linearelectronic board 20. - In one embodiment, each
power supply line - Each
lighting device 100; 100' is provided with mechanical connection means 102 suitable to interact with thebar body 12 for mechanically supporting thelighting device 100; 100' by means of thelighting bar 10. - Furthermore, each
lighting device 100; 100' is provided withelectrical connection needles 104 suitable to create an electrical contact with the second electricalpower supply line 26. - More in detail, each
lighting device 100 is provided with at least one pair of anchoringarms 108, each suitable to be inserted into a respectivelongitudinal side pocket 122 and to snap-engage theinner portion 12a and/or theouter portion 12b of thebar body 12 for mechanically supporting thelighting device 100 by means of thelighting bar 10. - According to the invention, the
electrical connection needles 104 are suitable to create an electrical contact with the second electricalpower supply line 26 by passing through theinsulating body 24. - In other words, the
electrical connection needles 104 are configured so as to pierce theinsulating body 24 until they abut against the respective conductors of the second electricalpower supply line 26. - In one embodiment, the anchoring
arms 108 and theelectrical connection needles 104 are configured to simultaneously obtain the mechanical and electrical connection of thelighting device 100; 100' with thelighting bar 10. - In one embodiment, the anchoring
arms 108 and theelectrical connection needles 104 extend from abase portion 106 of thelighting device 100; 100' resting against thelighting bar 10 when the anchoringarms 108 are coupled to thelighting bar 10. - In one embodiment, the
electrical connection needles 104 extend from aconnector 120 housed in thebase portion 106. Thisconnector 120 is configured to abut against a facingouter surface 24" of theinsulating body 24. For example, thisouter surface 24" is substantially flat. - In one embodiment, the
connector 120 is configured to create a calibrated interference with theouter surface 24", so as to prevent the penetration of external agents into the area where theinsulating body 24 is pierced by theelectrical connection needles 104. - For example, the
connector 120 forms, about eachelectrical connection needle 104 or about the whole area of theelectrical connection needles 104, anannular tooth 122 which, when thelighting device 100; 100' is coupled to thebar body 12, interferes with theouter surface 24" of theinsulating body 24, for example, exerting thereon a calibrated pressure which prevents the penetration of external agents inside the area of the insulatingbody 24 delimited by eachannular tooth 122. - In one embodiment, the
inner portion 12a and theouter portion 12b of thebar body 12 respectively comprise of an inner extruded section bar and an outer extruded section bar connected to each other. - For example, both section bars are substantially in the shape of a "U".
- In one embodiment, the
inner portion 12a has aninner bottom wall 34 and twoinner side walls 30; theouter portion 12b has anouter bottom wall 33 and twoouter side walls 35. - In one embodiment, the
inner bottom wall 34 is anchored to theouter bottom wall 33, for example by means ofscrews 37. - In one embodiment, each
outer side wall 35 is substantially parallel to and spaced apart from the respectiveinner side wall 30. Eachlongitudinal side pocket 122 is therefore delimited by aninner side wall 30 and by anouter side wall 35. - In some embodiments, an undercut 32 facing the respective
longitudinal side pocket 122 is obtained in each of theinner side walls 30. Each anchoring arm is provided with alocking tooth 110; 110' engageable by arelevant undercut 32 of theinner side wall 30. - In other words, the anchoring
arms 108 are elastic arms snapping into the locking position when thelocking tooth 110; 110' meets the undercut 32. - In some embodiments, the locking
tooth 110 has a curvilinear profile, so as to allow the disengagement thereof from the undercut 32 if thelighting device 100; 100' is pulled in a direction orthogonal to the bar axis (X) . - In other embodiments, instead, the locking tooth 100' is designed so as to prevent a separation of the
lighting device 110; 100' from thebar 10. - In one embodiment, the electrical connection needles 104 extend between and parallel to the anchoring
arms 108. - In one embodiment, the longitudinal
central seat 14 is delimited by abottom wall 34 and by the pair ofparallel side walls 30. Thelinear lighting source 18 rests on thebottom wall 34 and has a light beam emission surface substantially flush with the ends of theside walls 30. For example, theouter surface 24" of the insulatingbody 24 is substantially flat and coplanar with the ends of theside walls 30. - Thereby, when the
base portion 106 of thelighting device 100; 100' abuts against thebar body 12, or theside walls 30 thereof, the electrical connection needles 104 and the anchoringarms 108 extend completely inside thelighting bar 10. - As mentioned above, the
base portion 106 in contact with the insulatingbody 24 by means of theconnector 120 ensures the degree of protection which allows the use of the lighting system also outdoors. - In one embodiment, the electrical connection needles 104 are four in number: a
first needle pair 104a is aligned parallel to the bar axis X to intercept afirst conductor 26a of the second electricalpower supply line 26; asecond needle pair 104b is aligned parallel to the bar axis X and spaced apart in the transverse direction with respect to thefirst needle pair 104a to intercept asecond conductor 26b of the second electricalpower supply line 26. - Thereby, if the
linear lighting source 18 had such a length as to require, for production needs, interruptions of the copper tracks 26, 26b (as shown inFigure 4 ), and if alighting device 100, 100' was positioned, in a random manner, precisely straddling one of such interruptions, there is the certainty that at least one needle of each pair ofneedles respective conductor -
Figure 4 shows a positioning example of the pairs ofneedles linear lighting source 18, wherein a needle of each pair ends precisely at an interruption - for example of about 1mm - of theconductors electronic board 20. It can be noticed that, in this case, the other needle of each pair of needles is instead in contact with therespective conductor lighting devices 100, 100' is therefore always ensured, regardless of their position along thebar 10. - In one embodiment, the two
power supply lines power supply cable 132 electrically connected thereto at one end of the insulatingbody 24. For example, in order to ensure a high IP protection degree (for example IP67), the power supply cable is connected to the power supply lines by means of acap 130 made of insulating material (for example silicone), co-molded with the insulatingbody 24. - In one embodiment, shown in particular in
Figure 4 , theconductors power supply line 25 are obtained in a central portion of the linearelectronic board 20, so as to intersect the LEDs of a row of LEDs mounted along the median axis of the board.
