Light switching system

Abstract

 The invention provides a switching system for a building with separated living rooms (1), wherein each living room has electrically appliances (6) which are connected to operating elements (5), wherein the switching system (4) is designed to switch the electrical appliances (6) of two living rooms, and wherein the switching system is provided with an element (9), such as a switch of double switching type, with which the switching system at choice can be adapted as a first or a second, functionally different, type, the first type for a first and the second for a second lay-out type of the building.

Description

[0001] The design of office buildings is based on two types, office chambers (1) between which a central passage (2) as shown in fig. 1 and office buildings with a central core (3) and there around passages (2) and chambers (1) as according to fig. 2. The electrical installation comprising a light switching system or an electrically actuated sun blind is adapted according to the design of the office building.

[0002] For each office chamber illumination appliances or an electrically actuated sun blind (6) is switched by an operating element (5) such as switches, press buttons or movement detectors. Typically a switching module (4) can switch the illumination or sun blind of two office chambers (fig. 3 or 4). In a building according fig. 1 the opposite chambers are served by the same switching module, fig. 3. In buildings according to fig. 2 the switching module takes care of switching for two adjacent chambers, shown in fig. 4. A bus or system cable (7) provides mutual communication between the switching modules.

[0003] In fig. 5 the switching modules (4) for buildings according to fig. 1 are schematically shown. The coupling switch (8) is closed if the separation wall between adjacent chambers is removed. Both operating elements (5) then switch the common lamps/sun blinds (6).

[0004] In fig. 6 in the same manner the switching module required for buildings according to fig. 2.

[0005] In large office buildings both designs are often used simultaneously. It offers advantages in many respects if a switching module is generally applicable for both building types.

[0006] In fig. 7 the switching module of fig. 5 is shown, to which an additional switch (9) of the double switching type is added. Switch (9) in the position as shown makes the switching module functionally equal to the switching module of fig. 5 for buildings of the type chamber-passage-chamber. After switching the switch (9) a switch is obtained of the design according to fig. 6 for the building type with a core.

[0007] Above the invention is explained by a first embodiment as shown in fig. 7. It will be appreciated that the switching module by addition of switch 9 is multi functional applicable, which a.o. lowers the inventory costs and also increases the production volume per type, such that a production costs advantages can be obtained. It is also easier to re-use the switching module.

[0008] Fig. 8 shows a further development of the switching module of fig. 7, based on the use of so called bi-stable or remanent magnetic relais 10, by which the power consumption is limited. If different relais types are used, the components (transistors, resistants and capacitors) be eliminated, which in the embodiment according to fig. 8 are added such that said relais 10 can operate.

[0009] The relais 11 is added for an additional function, e.g. switching of the passage lamps, e.g. acting via a separate lead 12 to be operatable from a central post.

[0010] The further reference signs in fig. 8 refer to elements/components/units of similar nature or function as the elements/components/units of fig. 7, refered by the same reference signs.

[0011] Fig. 9 shows the ranking of the galvanic components at a wired board for a switching module as based on the embodiment as shown in fig. 8.

[0012] It will be appreciated that also embodiments different from the one shown in fig. 7 and/or 8 are within the field of this invention, e.g. based on the provided disclosure. An embodiment is contemplated based on one or more separate aspects of the disclosed embodiment, possibly in combination with one or more aspects from the prior art and/or one or more further aspects from an embodiment as disclosed.
