Definitions

  • the present invention relates to an improved adapter for supporting and electrically connecting a lighting apparatus to an electrified track, particularly suitable for the support and the electrical connection of elongated lighting apparatus or linear lighting apparatus.
  • the present invention also relates to a lighting unit employing said adapter.
  • the electrified track system for supporting and connecting lighting apparatus is designed for lighting specific points or limited areas, respectively, for example by means of spotlights or downlights.
  • this system offers a high degree of flexibility in relation to the number and position of the lighting apparatus that can be connected, allowing them to be easily moved, added or removed.
  • Components are known for attaching and electrically connecting the spotlights to the electrified track, which have the dual function of ensuring the electrical and mechanical connection between the electrified track and the spotlight, also known as electromechanical support and connection adapters.
  • Known adapters are provided with a system for attaching to the track usually involving a double insert operation into the track and subsequent locking by turning levers that at the same time cause the extraction of both suspension flaps and of the electrical contacts.
  • An example of one such adapter, according to the preamble of claim 1, is disclosed in document DE 3812586 A1 .
  • adapters of known type are not able to offer such a result.
  • the space that is necessary in order for the installer to be able to mount the known adapters in the track such as the space that allows the lever to turn, and the encumbrance of the adapters themselves, are two factors which, on the one hand, affect the continuity of light, creating shaded areas between one apparatus and the other due to the presence of the adapter and the space required for the fixing operations and on the other hand, they do not offer an optimal result in terms of size reduction and miniaturization of the solutions, in that once installed the devices do not adhere perfectly to the track.
  • the Applicant has therefore felt the need to make an adapter for supporting and electrically connecting a lighting apparatus to an electrified track especially designed for the installation of linear lighting apparatus, thus not being subject to the above drawbacks.
  • the problem underlying the present invention is to devise an adapter for supporting and electrically connecting a lighting apparatus to an electrified track that allows imparting to a set of linear lighting apparatus installed on the track the effect of a single body without discontinuity or, in other words, light without interruption or shaded areas.
  • one object of the present invention is to make an adapter for supporting and electrically connecting a lighting apparatus to an electrified track that allows installing linear lighting apparatus in perfect adherence to both the electrified track and to any adjacent lighting apparatus, in case of continuous row installation.
  • one object of the present invention is to devise an adapter for supporting and electrically connecting a lighting apparatus to an electrified track that simplifies installation by obtaining the insertion into the track as well as the extraction of the suspension flaps and electrical contacts substantially with a single action.
  • the invention therefore relates to an adapter for supporting and electrically connecting a lighting apparatus to an electrified track, comprising a box-like body at whose interior a mechanism is housed for extracting and retracting at least one electrical contact such that the box-like body is able to assume a first compact configuration, wherein the at least one electrical contact is substantially housed inside the box-like body, and a second configuration wherein the at least one electrical contact is at least partially extracted from the box-like body, the box-like body being associated with at least one interface element for coupling to a lightning apparatus and is characterized in that the interface element is movable between a first extracted configuration and a second retracted configuration with respect to the box-like body, wherein the retraction and extraction movements respectively determine the passage of the box-like body from its first compact configuration to its second extracted configuration and vice versa.
  • the Applicant has found that due to the particular conformation of the interface element to the lighting apparatus and its interaction with the insertion and retraction mechanism of at least one electrical contact, it is possible to mount the adapter into the electrified track and electrically connect it substantially with a single action. Installation operations therefore become quicker and easier.
  • This feature also allows, on the one hand, making the electrified tracks without providing appropriate spaces for moving the controls for the extraction of the electrical contacts and/or any suspension flaps. On the other hand, it allows housing substantially the entire adapter within the electrified track. This makes it possible to install the lighting apparatus substantially without shaded areas or interruptions, in the case of installation of a plurality of lighting apparatus in a row, thus obtaining the effect of a single body without discontinuity.
  • the invention relates to a lighting unit comprising a lighting apparatus preferably of the linear type, provided with a support element and with at least one light source constrained to the same, and an adapter for supporting and electrically connecting the lighting apparatus to an electrified track and is characterized in that the adapter is of the type described above.
  • the lighting unit according to the invention achieves the technical effects described above in relation to the adapter for supporting and electrically connecting a lighting apparatus to an electrified track.
  • the present invention may have at least one of the following preferred features; the latter may in particular be combined with each other as desired to meet specific application requirements.
  • the at least one interface element comprises a cam that cooperates with the extraction and retraction mechanism and determines the actuation thereof.
  • the extraction and retraction mechanism comprises a support element that carries the electrical contacts on a first side and a projection on a second side transverse to the first.
  • the projection is engaged in the cam such that a first translational movement in retraction and extraction of the at least one interface element with respect to the box-like body determines a second translational movement of the support element along a direction transverse to the first movement.
  • this allows obtaining both the insertion of the adapter inside the track and the electrical connection to the same with a single action. It is in fact sufficient for the installer to push the adapter inside the track up to reach the condition in which the interface element is also fully inserted. In such a configuration, in fact, it has already been obtained that the electrical contacts are in their extracted configuration of connection to the conductors of the track.
  • the support element carries at least one support flap on the first side, the at least one support flap being able to assume a first configuration of full housing inside the box-like body and a second configuration of at least partial extraction from the box-like body, the passage between the first and the second configuration of the support flap being carried out through the movements of the at least one interface element in retraction and extraction from the box-like body.
  • the extraction of the support flaps is also carried out by the same insertion action.
  • a firm constraint of the adapter, and therefore also of the light apparatus, to the electrified track is thus ensured.
  • the at least one electrical contact and the at least one support flap are extractable from the box-like body through corresponding openings formed on the surface of the same.
  • the at least one interface element comprises means for blocking the translation with respect to the box-like body.
  • the blocking means comprise a hook which, in non-use condition of the adapter, is adapted to engage in a blocking opening formed on the outer surface of the box-like body.
  • the hook is maintained in its engagement position with the blocking opening by elastic means.
  • This advantageous device allows, before use, keeping the adapter in an extracted configuration.
  • the blocking opening is formed on the surface of the box-like body in such a position whereby, once the box-like body is substantially inserted in the electrified track, the hook is brought into a condition of disengagement with respect to such a blocking opening in contrast to the action of the elastic means.
  • this device allows one to automatically deactivate the blocking means once the adapter is in condition of substantial insertion into the track.
  • the installation operation can therefore take place substantially in continuity without the need of special operations for releasing the interface elements.
  • the at least an interface element has an upturned T plan shape.
  • the at least one interface element comprises a first portion shaped as a stem insertable into the box-like body and a second portion having at least one end part adapted to engage with a connection interface of the lighting apparatus.
  • the box-like body comprises, on an outer surface thereof, a plurality of engagement flaps with an inner wall of the electrified track.
  • the engagement flaps interfere with the inner wall of the electrified track, resulting in a condition of first engagement between the two elements.
  • the engagement flaps have a chamfered conformation.
  • the conformation of the engagement flaps is such as to facilitate the removal of the adapter from the track, despite the condition of engagement with the inner wall of the same.
  • the box-like body has an elongated shape along an axis of development and is associated with two interface elements for fastening the lighting apparatus arranged mutually spaced apart with respect to the axis of development.
  • the support element of the lighting apparatus comprises at least one interface recess for the connection to at least one end part of the at least one interface element, the at least one recess and the at least one end part having complementary conformation so as to mutually engage and therefore assume a support configuration of the lighting apparatus by the at least one interface element.
  • the support element comprises at least one supplementary support accessory suitable for engagement in the electrified track.
  • the supplementary support accessory is associated to the adapter, thus contributing to the support of the lighting apparatus on track 60.
  • a lighting unit 10, 50 comprising a lighting apparatus 50 and an adapter 10 for supporting and electrically connecting such a lighting apparatus 50 to an electrified track 60.
  • the lighting apparatus 50 comprises a profiled element 52 which acts as a support of a LED light source 53.
  • the profiled element 52 of the lighting apparatus 50 further implements a pair of interface recesses 51 for connecting to adapter 10.
  • the electrified track 60 shown comprises a profiled element 62 provided with a plurality of sub-profiles 61 projecting inwards, made of an insulating material for defining single housings for a plurality of electrical conductors 63.
  • Adapter 10 for support and electrical connection comprises a box-like body 11 having an elongated conformation along an axis of development, which houses the electronics 30 required for the power supply of the lighting apparatus 50 and an extraction and retraction mechanism 20 of a plurality of electrical contacts 21, 22, 23, for connecting electronics 30 to the electrical conductors 63 of the electrified track 60.
  • the ground contact 26 projects above the box-like body 11, which when the adapter is inserted into track 60, contacts the profiled element 62 of the same 60.
  • the box-like body 11 can assume a first compact configuration, in which the electrical contacts 21, 22, 23 are substantially housed within the box-like body 11 (see figures 3a-3c ), and a second configuration in which the electrical contacts 21, 22, 23 are at least partially extracted from the box-like body 11 (see figures 3d and 3e ).
  • the box-like body 1 is associated with two interface elements 12, 13 for fastening the lighting apparatus 50 arranged mutually spaced apart with respect to the axis of development A.
  • the interface elements 12, 13 have an inverted T plan shape, comprising a first portion 12a, 13a shaped as a stem insertable into the box-like body 11 and a second portion 12b, 13b placed transverse to the stem portion 12a, 13a.
  • the second portion 12b, 13b has a pair of end parts 12b', 13b' with a conformation complementary to the respective connection interfaces 51 provided on the profiled element 52 of the lighting apparatus 50 so as to come into mutual engagement and therefore assume a support configuration of the lighting apparatus 50 by the interface elements 12, 13.
  • the interface elements 12, 13 are movable between a first extracted configuration and a second retracted configuration with respect to the box-like body 11.
  • the retraction and extraction movements respectively cause the switching of the box-like body 11 from its first compact configuration to its second configuration with contacts 21, 22, 23 extracted, and vice versa.
  • the first portion 12a, 13a of at least one of the two interface elements 12, 13 comprises a cam 14 that cooperates with the extraction and retraction mechanism 20 and determines the actuation thereof.
  • the extraction and retraction mechanism 20 comprises a support element 24 that carries the electrical contacts 21, 22, 23 in addition to a support flap 27 on a first side, and a projection 25 on a second side transverse to the first, which engages with cam 14.
  • cam 14 and projection 25 is such that a translation of the interface element 12, 13 inwards of the box-like body 11 determines a translation of the support element 24 in the transverse direction, making the electrical contacts 21, 22, 23 and the support flap 27 come out of the box-like body 11 through corresponding openings 15, 15' made on surface 11a of the same 11.
  • the box-like body 11 comprises, on its outer surface 11a, a plurality of engagement flaps 16a, 16b, which with adapter 10 at least partially inserted into the electrified track 60, interfere with the plurality of sub-profiles 61 inside said track 60, resulting in a condition of first engagement between the two elements (engagement flaps 16a, 16b and sub-profiles 61).
  • engagement flaps 16a, 16b have a chamfered conformation to facilitate the removal of adapter 10 from track 60, despite the condition of engagement with sub-profiles 61 within track 60.
  • the interface elements 12, 13 comprise blocking means 17 of the translation with respect to the box-like body 11 provided with a hook 17a which, in non-use condition of adapter 10, engages in a blocking opening 18 formed on the outer surface 11a of the box-like body 11.
  • Hook 17a is maintained in the engagement position with the blocking opening 18 by elastic means 19 well shown in figure 3 .
  • the blocking opening 18 is formed in such a position whereby, once the box-like body 11 is substantially entirely inserted in the electrified track 60, hook 17a is brought into a condition of disengagement with respect to such a blocking opening 18.
  • a lower wall 62a of the profiled element 62 of the electrified track 60 that defines the inlet opening inside track 60 presses against hook 17a protruding from the blocking opening 18, thus counteracting the action of the elastic means 19. This releases the possibility of translation of the respective interface element 12, 13 inward of the box-like body 11.
  • the lighting apparatus 50 comprises a supplementary support accessory 54 which, inserted into the profiled element 52 of the lighting apparatus 50 and alongside adapter 10 contributes to the support of the profiled element 52 to track 60.
  • adapter 10 for supporting and electrically connecting the lighting apparatus 50 to the electrified track 60 is as follows.
  • hook 17a By inserting the box-like body 11 within the electrified track 60, as shown in figures 2b and 3b , hook 17a increasingly approaches the inlet opening within track 62 up to engage with the lower wall 62a of the profiled element 62.
  • the engagement flaps 16a, 16b are engaged with sub-profiles 61, resulting in a first condition of engagement, although not fixed, of adapter 10 within the electrified track 60.
  • the sliding of the interface elements 12, 13 inside the box-like body 11 determines the activation of the extraction and retraction mechanism 20.
  • projection 25 of the support element 24 is constrained to translate within cam 14 made on the interface elements 12, 13.
  • a vertical translation of such elements 12, 13 due to the push exerted by the installer automatically makes the support element 24 translate horizontally.
  • contacts 21, 22, 23 carried by the support element 24 in addition to the support flaps 27 protrude from the box-like body 11 through the corresponding openings 15, 15'.
