Abstract

The invention comprises a switch suitable for forwarding at least two functions to a lighting system.

Claims

1. Switch, suitable for forwarding at least two functions to a lighting system, wherein the switch comprises the following elements:

a sensor, configured to detect a contact;

an illuminating element;

an LED, wherein the LED can assume a plurality of colours, and wherein the LED is configured to illuminate the illuminating element; and

an electronic circuit, configured to measure the time period of contact with the sensor, and configured to select a function from the at least two functions;

wherein the selection of a function from the at least two functions is dependent on the time period in which the sensor is contacted, and wherein the colour of the LED varies depending on the time period in which the sensor is contacted, wherein the electronic circuit is configured to control the LED with a periodic colour change during contact with the sensor.

2. Switch according to claim 1, wherein the electronic circuit comprises the following elements:

a contact-sensitive circuit, coupled to the sensor;

a microprocessor, configured to measure the time period of contact; and

a communications bus, configured to receive a signal from the microprocessor;

wherein the communications bus forwards the selected function to the lighting system.

3. Switch according to claim 2, wherein the contact-sensitive circuit comprises a capacitive circuit.

4. Switch according to claim 2, wherein the communications bus is selected from the list comprising:

KNX, LON, Can-bus, RS485 and BACNET, preferably KNX.

5. Switch according to claim 2, wherein the communications bus is configured to receive a signal from the lighting system and forward it to the microprocessor.

6. Switch according to claim 1, wherein the selected function comprises the switching on and/or off of one or more light points and/or light circuits.

7. Switch according to claim 1, wherein the selected function comprises the switching on of a specific light ambience in the lighting system, preferably wherein a light ambience is determined by:

a selection of switched on light points;

a selection of switched off light points;

optionally, the light level of switched on light points; and

optionally, the light colour of switched on light points.

8. Switch according to claim 7, wherein the light ambience comprises one or more intelligent home applications.

9. Switch according to claim 6, wherein one of the at least two functions comprises the switching on and/or off of one or more light elements, and wherein another of the at least two functions comprises the switching on of a specific light ambience in the lighting system.

10. Switch according to claim 1, wherein the sensor consists of metal, preferably aluminium or brass.

11. Switch according to claim 1, wherein the illuminating element is translucent, preferably made from a glass or plastic, for example plexiglass or acrylate.

12. Switch according to claim 1, wherein the sensor consists of a plurality of partial surfaces which each send out a different electronic signal to the electronic circuit.

13. Switch according to claim 12, wherein contact with an individual partial surface controls individual light points or light circuits, while contact with two or more partial surfaces selects a light ambience.

14. Method for selecting a specific light ambience with a switch according to claim 1, comprising the following steps:

a) recording of the contact with the sensor, by means of the electronic circuit;

b) controlling of the LED with a periodic colour change by the electronic circuit, during contact with the sensor;

c) recording of the stopping of the contact with the sensor, by means of the electronic circuit;

d) determining of the time period of contact by the electronic circuit;

e) selecting of a function depending on the time period of contact by the electronic circuit; and

f) sending out of a signal with a selected function by the electronic circuit to a lighting system.

15. Method according to claim 14, wherein steps a) to e) are carried out by a microprocessor and step f) is carried out by a communications bus.
