Definitions

  • the present invention relates to a lighting device comprising a fitting and a plurality of lighting modules which can be mounted therein.
  • the invention likewise relates to a fitting for use in such a device and to a lighting module for use in such a device.
  • Lighting devices of the type described in the preamble such as so-called track lighting, where lighting modules can be mounted in a rail or track, are known. Such lighting devices are limited in respect of the design of the fitting (typically a straight profile). Such lighting devices further often have the drawback that the electrically conductive tracks in the fitting are clearly visible or that complex solutions are necessary in order to make them less visible.
  • the present invention has for its object to provide a lighting device which is simple and robust, which allows the fitting of the lighting device to take many different forms, and which allows modular use.
  • the lighting device has for this purpose the features of claim 1.
  • the lighting device comprises a fitting and one or more lighting modules which can be mounted therein.
  • the fitting comprises a profile and a carrier.
  • the carrier has an inner side and an outer side. The inner side is mounted against the profile.
  • the outer side is provided with at least one first electrically conductive track of a first material. Each first electrically conductive track is covered (coated) with a second electrically conductive track which is manufactured from a second material.
  • the one or more lighting modules each comprise a light source and at least one electrical contact element connected thereto.
  • the one or more lighting modules can be coupled to the fitting such that the at least one electrical contact element makes contact with the at least one second electrically conductive track.
  • the first material has a greater electrical conductivity than the second material.
  • this carrier can be mounted on or in different types of fitting, wherein the profile of the fitting may optionally have a curvature.
  • this second track can be given a colour which is not very noticeable on the profile.
  • the invention is based inter alia on the insight that the conductivity of the second electrically conductive track only makes a substantial contribution over a limited length, i.e. there where the contact element makes contact with the second electrically conductive track. This is because the resistance between two lighting modules will be substantially determined by the first electrically conductive track with the highest conductivity.
  • the class of materials with a lower conductivity allows for the colour of the second material to be chosen from a much wider range of colours, and the second electrically conductive track can thus be given a suitable colour in accordance with the desired colour of the profile.
  • the first material is preferably a metal or a metal alloy, typically copper.
  • the first conductive track can thus be a standard copper track on a flexible PCB.
  • the second material preferably comprises a binder such as a paint or an ink, and electrically conductive particles such as graphite.

  • the second electrically conductive track is for instance a printed, sprayed or dispersed electrically conductive flexible layer.
  • the surface resistance of the second electrical track is preferably smaller than 100 ohm/square, still more preferably smaller than 80 ohm/square and most preferably smaller than 60 ohm/square.
  • the surface resistance is measured with a four-point probe measurement at 20°C.
  • the contact resistance is preferably smaller than 6 ohm, still more preferably smaller than 5 ohm and most preferably smaller than 4 ohm.
  • the second electrical track is for instance an electrically conductive graphite layer.

  • the carrier and the at least one first electrically conductive track form part of a flexible PCB.
  • This track can then be covered with the second material in simple manner for the purpose of forming the second electrically conductive track.

  • the profile can describe a line or arcuate segment or a closed periphery.
  • the at least one first and second electrically conductive track is preferably arranged along at least 70% of the periphery of the profile, more preferably along at least 90% of the periphery of the profile, still more preferably along the whole periphery of the profile.
  • the profile is elongate with a length.
  • the at least one first and second electrically conductive track is then preferably arranged along at least 70% of the length of the profile, more preferably along at least 90% of the length of the profile, still more preferably along substantially the whole length of the profile.
