Abstract

The invention relates to controlling a lighting system by proximity sensing of a spotlight control device, particularly to controlling a spotlight generated by a lighting system such as a large LED lighting array by means of a spotlight control device. The invention provides a device (10) for controlling a lighting system (12) by proximity sensing of a spotlight control device (14), wherein a predefined area (24) around the spotlight control device (14) is illuminated if a proximity sensor (16) signals presence of the spotlight control device (14) within the predefined area (24). The invention has the main advantage that it allows to control complex lighting systems containing dozens or even thousands of lighting devices such as large LED arrays with one device, the spotlight control device.

Claims

1. A device for controlling a lighting system by proximity sensing of a spotlight control device and a spotlight control device, the devices comprising:

at least one proximity sensor for sensing the spotlight control device within an area in the proximity of the lighting system, and

a light switch for controlling lighting devices of the lighting system depending on a signal of the at least one proximity sensor such that a predefined area around the spotlight control device is illuminated if the at least one proximity sensor signals presence of the spotlight control device within the predefined area;

wherein the light switch is configured to switch off the lighting devices if the at least one proximity sensor no longer signals presence of the spotlight control device within the predefined area;

said spotlight control device having at least one of a beam width button, a beam intensity button, and a beam color button;

a signal transmitter on said spotlight control device activated by pressing the at least one of a beam width button, a beam intensity button or a beam color button;

said spotlight control device further adapted to generate a light control signal upon activation of the at least one of the beam width button, the beam intensity button or the beam color button.

2. The devices of claim 1, said light switch further comprising a receiver receiving said light control signal for toggling an illumination control indicator, wherein the light switch controls the lighting devices depending on the status of the illumination control indicator.

3. The devices of claim 1, wherein the at least one proximity sensor is adapted to detect a presence signal from the spotlight control device.

4. The devices of claim 3, wherein the presence signal is at least one of a radio signal, a light signal, or a sound signal.

5. The devices of claim 4, wherein the at least one proximity sensor comprises a near field communication device.

6. The devices of claim 4 wherein the at least one proximity sensor uses real-time location-aware sensing technologies based on ultrawide band or ultrasound.

7. The devices of claim 1, wherein the at least one proximity sensor is adapted to transmit a detection signal for the spotlight control device within its supervised area.

8. The devices of claim 1, wherein the light switch is adapted to store and load a lighting configuration in a memory of the light switch.

9. A spotlight control device in combination with a device for controlling a lighting system, comprising:

at least one proximity sensor of the device for controlling a lighting system for sensing the spotlight control device within an area in the proximity of the lighting system,

a light switch of the device for controlling a lighting system for controlling lighting devices of the lighting system depending on a signal of the at least one proximity sensor such that a predefined area around the spotlight control device is illuminated if the at least one proximity sensor signals presence of the spotlight control device within the predefined area,

a memory button of the spotlight control device, and

signaling means of the spotlight control device activated by pressing the memory button and configured to generate a light control signal upon activation, received and processed by the light switch in that the light switch remembers the current illumination even if the at least one proximity sensor no longer signals presence of the spotlight control device within the predefined area;

said spotlight control device further having at least one of a beam width button, a beam intensity button, and a beam color button; and

wherein the signaling means are activated by pressing the at least one of a beam width button, a beam intensity button, and a beam color button; and

are further adapted to generate a light control signal upon activation of the at least one of the beam width button, the beam intensity button, and/or the beam color button received and processed by the light switch.

10. The spotlight control device in combination with a device for controlling a lighting system of claim 9, further comprising a configuration button and wherein the signaling means are activated by pressing the configuration button and are further adapted to generate a light control signal upon activation of the configuration button which may be received and processed by the light switch in that a certain lighting configuration may be stored in or load from a memory of the light switch.

11. A lighting system including a spotlight control device and a light switch, comprising:

a spotlight control device;

a plurality of proximity sensors, said sensors each adapted to sense said spotlight control device within a predefined surveillance area in the proximity of the lighting system,

a light switch in electrical communication with lighting devices of the lighting system, said light switch manipulating said lighting devices depending on one or more signals from said proximity sensors such that a predefined illumination area around the spotlight control device is illuminated if at least one of said proximity sensors signals presence of the spotlight control device within its said predefined area, wherein its said surveillance area overlaps with said predefined illumination area;

said spotlight control device having at least one of a beam width button, a beam intensity button, and a beam color button;

a signal transmitter on said spotlight control device activated by pressing the at least one of a beam width button, a beam intensity button or a beam color button;

said spotlight control device further adapted to generate a light control signal upon activation of the at least one of the beam width button, the beam intensity button or the beam color button.

12. The lighting system of claim 11, wherein said predefined surveillance area of some of said proximity sensors overlaps with said predefined surveillance area of other of said proximity sensors.

13. The lighting system of claim 11 wherein said light switch is configured to no longer illuminate said predefined illumination area if said at least one proximity sensor no longer signals presence of said spotlight control device within its said predefined surveillance area.
