Definitions
- the present invention generally relates to a ceiling system comprising a supporting structure comprising a plurality of main runners made of an electrically conductive material and an electric device supported by the main runners.
- a suspended ceiling system in a room or in another accommodation may serve a variety of purposes.
- One purpose of having a suspended ceiling system may be to conceal an underside of a space, such as another room, which is located above the room.
- Another purpose may be to provide improved noise absorption and/or noise attenuation in and outside of the room.
- the resulting plenum space located between the suspended ceiling and a main ceiling of the room may further be utilized to accommodate e.g. wiring, piping, as well as devices related to heating, ventilation and air condition.
- the suspended ceiling consists of a plurality of ceiling tiles which are fitted into a supporting grid of profiles which is mounted in the main ceiling.

This approach is however time consuming, expensive and does significantly hamper the flexibility when it comes to positioning the power consuming objects in the suspended ceiling.

- the connectors may be partially recessed in the electrical device.

- 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.
