Definitions

  • the present invention relates to a lighting device with an electrified track and with high-efficiency lighting elements. Technological background
  • electrified bars are already used in the lighting field and are constituted in general by profiled sections, inside which seats are defined for housing electrical conductors, and which have further seats for the mechanical engagement of a lighting body which can be positioned freely at any point on the track.
  • Lighting elements of the LED type which are used, for example, for lighting in furniture and kitchens and which have a particularly good type of light, as well as "sport ring” LEDs, which have a plurality of lighting elements distributed on a single plate in a manner such as to have a characteristic illumination which is
  • lamps of this type have the disadvantage of having particularly rigid and restrictive elements for connection to the supports so that their installation becomes problematical in many situations and, moreover, is not such as to allow free positioning of the light sources.
  • Description of the invention The aim of the invention is precisely to eliminate the disadvantages discussed above, providing a lighting device with an electrified track and with high-efficiency lighting elements which enables the types of lamps usable with the tracks to be extended considerably, thus achieving a considerable improvement in lighting quality.
  • Another object of the present invention is to provide a track lighting device in which the configuration and aesthetic type of the lamp can be changed, without the need to change the technical connection characteristics.
  • Yet another object of the present invention is to provide a lighting device which, owing to its particular constructional features, can provide very extensive guarantees of reliability and safety in use.
  • a principal object of the present invention is to provide an electrified track with high-efficiency lighting elements which can easily be produced from conventional commercially-available materials and which is also competitive from a purely economic point of view.
  • a lighting device with an electrified track and with high-efficiency lighting elements comprising a profiled body defining means for releasable engagement with a contact element supporting at least one light source, characterized in that the at least one light source is a LED-type lighting element and in that the contact element comprises a plate supporting the LED-type lighting element and defining electrically-conductive portions which can be arranged in contact with electrical conductors provided in the profiled body.

  • - Figure 5 is a perspective view of the lighting element from above, showing the foot for connection to the profiled body
  • FIG. 6 shows the lighting element with the casing, schematically and in section. Preferred embodiments of the invention.
  • the lighting device comprises a profiled body, generally indicated 1 , which is advantageously substantially C- shaped in cross-section with an open portion partially closed by lips 2 which are resiliently yielding since they are made of elastomeric material, such as synthetic mouldings.
  • a contact element generally indicated 4, which supports a light source.
  • the engagement means are preferably formed by an engagement seat 5.
  • the light source is constituted by a LED-type lighting element, indicated 10, which projects from the resilient lips 2, thus enabling access to the interior of the profiled body which constitutes the track to be closed against dust and dirt whilst permitting easy movement of the assembly.
  • the contact 4 is preferably formed by a plate 4a which has on its surface, a printed circuit defining electrically-conductive portions, the conductive surfaces 7 of which can be positioned in the region of electrical conductors 8 which are provided inside the profiled body 1 in order to perform the electrical connection of the lighting element 10.
  • the conductive surfaces 7 form "flash"-type contacts and are gold-plated to a thickness of 35 //m.
  • the LED 10 is fixed to the plate 4a by means of a two-part, thermally- conductive glue and is soldered by means of a tin-lead alloy.
  • the LED 10 is supplied with energy with the interposition of an electrical resistance (not shown) to limit the current supplied to the LED 10 and thus to enable several LEDs 10, mounted on different plates 4a, to be mounted in parallel. To keep the conductive surfaces 7 correctly in contact with the conductor
  • a resilient projection 15 is provided inside the profiled body and, in practice, is formed by a bridge which joins the opposed inside edges of the profiled body 1 and engages a central portion of the plate 4a, which is thus kept pressed against the conductors 8, forming a firm contact therewith.
  • the plate 4a which supports the LED can be positioned inside the profiled body simply by sliding, since it is fitted in from the exterior and is brought to the desired position simply by sliding.
  • the arched bridge in practice forms a spring which maintains the electrical contact for the LED.
  • a lighting element again formed by a LED 10 supported by the plate 4a, is provided and is housed inside a casing, indicated 20 and constituted by a base 21 connected to which is a cover 22 which defines the opening 23, through which the LED projects.
  • the casing also has a foot 30 which permits connection to a general track, indicated 31 , which is electrified.
  • the foot 30 is constituted by an oblong body 33 which has one dimension such that it can be inserted between arms 32 of the track 31 , and a larger, transverse dimension so that it can be locked beneath the arms 32 by rotation through 90°.
  • the casing 20 has the characteristic that it defines, in its interior, connection contacts, indicated 40, which engage the conductive surfaces 7 of the plate 4a and project to the exterior, defining arc-like contact elements 41 which extend in the region of the foot 30 and can be arranged in electrical contact with the conductors that are provided on the track 33, as shown in Figure 3.
  • Resilient plates 35 are also provided inside the casing and have the function of maintaining the correct position of the element for contact with the lighting element inside the casing.
  • the casing can act as a decorative element which may adopt any desired shape, for example, a stylized flower corolla. It is clear from the foregoing description that the invention achieves the objects proposed and, in particular, it is stressed that the invention provides a lighting device with an electrified track which makes it possible to use LED-type lighting elements particularly advantageously.
