  • a short circuit may originate from a wrongfully mounted cross runner 105 or from a defect cross runner 105 void of sufficient insulation in respect to the main runners 104a-e.
  • the power supply 114 may monitor and transmit an alarm if a short circuit occurs.
  • the ceiling system 100 has been described in a general manner for reasons of simplicity, the ceiling system 100 has mainly been described so as to include electric devices 110, 112, 110a in form of light sources.
  • the described ceiling system 100 may equally well be used with other electric devices such as loudspeakers, sensors, ventilation units, Wi-Fi access points, displays, fans, emergency light sources, cameras and power supplies to give a few relevant examples.
  • other types of electric devices 110, 110a, 112 may equally well be powered by the voltage V applied by the power source 114 between the main runners 104a and 104b.
  • other types of electric devices 110, 110a, 112 may equally well be powered by the voltage V applied by the power source 114 between the main runners 104b and 104c.By powering a power supply by the voltage V applied by the power source 114 between the main runners 104a and 104b or by the voltage V applied by the power source 114 between the main runners 104b and 104c, a voltage different form the voltage V may be realized in the system. It is thus possible to power electric devices requiring different voltages simultaneously be the system 100. Further, if an adjustable power supply is powered by the voltage V, a plurality off different voltages different from the voltage V may be realized in the system 100.
  • the system 100 of Fig. 1 is illustrated in a simplified manner.
  • the system 100 includes a plurality of main runners 104a-d.
  • the main runners 104a-d may be supported by a set of carrier profiles 132.
  • the depicted carrier profiles 132 overlies and supports the main runners 104a-d.
  • the carrier profiles 132 overlies and supports all five main runners 104a-d of Fig. 2 .
  • the carrier profiles 132 may overlie and support any number of main profiles 104a-d.
  • different carrier profiles 132 may overlie different number of main runners 104a-d.
  • the carrier profiles 132 are made of an electrically conducive material
  • the carrier profiles 132 are preferably electrically insulated with respect to the main runners 104a-d in order to prevent short circuit between adjacent main runners 104a-d of different polarities.
  • the carrier profiles 132 may in certain cases be electrically insulted with respect to main runners 104a-d having a certain polarity.
  • the electrical insulation between the carrier profiles 132 and the main runners 104a-d may for instance be achieved by providing a sheet of an insulating material between the carrier profiles 132 and the main runners 104a-d at locations where the carrier profiles 132 and the main runners 104a-d overlap.
  • FIG. 3 here is conceptually depicted a ceiling system 100 being similar to the ceiling system depicted in Fig. 1 .
  • the description of the ceiling system 100 of Fig. 1 is equally applicable to the ceiling system 100 depicted in Fig. 3 , why only relevant differences between the respective ceiling systems 100 will be described below in order to avoid undue repetition.
  • the ceiling system 100 of Fig. 3 comprises a further power source 114' apart from a single power source 114 as described and depicted in conjunction with Fig. 1 . More specifically, the ceiling system 100 of Fig. 3 is employed with two power sources, namely the power sources 114 and 114'. Similarly, to what has been described in conjunction with Fig. 1 above, the power source 114 is arranged to apply an electric voltage V between respective adjacent main runners 104a-c. More specifically, an electric voltage V is applied between the main runners 104a and 104b by power source 114. Correspondingly, an electric voltage V is applied between the main runners 104b and 104c by power source 114.
  • the further power source 114' is arranged to apply an electric voltage V' between respective adjacent main runners 104a'-c'. More specifically, an electric voltage V' is applied between the main runners 104a' and 104b' by power source 114'. Correspondingly, an electric voltage V' is applied between the main runners 104b' and 104c' by power source 114'.
  • the polarity of the respective power sources 114, 114' may not be reversed, i.e. the polarities may be equal for the power sources 114, 114'.
  • the main runners 104a and 104c' forming the space 109 will have the same polarity in practice bringing about that no voltage is applied between the main runners 104a and 104c'.
  • the space 109 may however advantageously be used for receiving conventional ceiling tiles 120.
  • an electric device 112' is supported by the main runner 104b' and 104c'and consequently arranged in the space 106'.
  • the electric device 112' is provided with connectors 116', 118'.
  • the connector 116' of the electrical device 112' is in electrical contact with the main runner 104c'.
  • the connector 118' of electrical device 112' is in electrical contact with the main runner 104c'. In this way, the electrical device 112' may be powered by the electric voltage V' applied by the power source 114' between the main runners 104b' and 104c'.
  • the electrical device 112' may be controlled as described above in conjunction with Fig. 1 . How the electrical device 112' may be controlled will consequently not be described in order to avoid undue repetition.
  • Power source 114' may be arranged to power further electric devices arranged in the spaces 106'and 108'.
  • the system 100 may include further power sources apart from one or two power sources as described above. If further power sources are introduced, further main runners are also introduced correspondingly.
  • a power source and the main runners connected thereto may be said to form a zone or a module capable of powering a plurality of electric devices.
  • Such zones or modules may for instance be arranged side bay side as depicted in Fig. 3 or may be arranged one after another along a common direction. In the latter case, the main runners of the respective modules may extend along a common direction and may coincide along common geometric lines. The main runners of the respective modules are may then typically discontinued so as to be electrically separated although extending along a common line or lines.
  • Respective modules or zones of a ceiling system may extend side by side and/or one after another.
