Abstract

A remote control device for controlling lighting systems includes a sensor configured to determine a location of the remote control device in relation to the lighting systems. A controller is configured to determine a nearest light source of the lighting systems relative to the location of the remote control device and to control this nearest light source. The controller is configured to change a configuration of the remote control device in response to changing its location. A transceiver transmit a signal to multiple light sources which measure the strength and/or time of flight of this signal for use in determining the location of the remote control device. The light sources provide the remote control device with identifying information unique to each one of them including their locations.

Claims

1. A user interface device (UID) for controlling one or more lighting systems having one or more light sources, the UID comprising:

a sensor determines a location of the UID in relation to said one or more lighting systems, said sensor determines said location based on information carried in one or more signals emitted by the one or more light sources, said one or more light sources measures at least one of a strength and a time of flight of a UID signal from said UID and sends said measured at least one of strength and time of flight of said UID signal to the UID which determines said location of the UID, wherein the one or more light sources communicate wirelessly with the UID; and

a controller determines at least a nearest light source of said one or more lighting systems relative to said location of said UID and controls at least one lighting attribute of said nearest light source in accordance with said location based on parameters, presets or modes of operation associated with the nearest light source or with a group of light sources including the nearest light source.

2. The user interface device of claim 1, wherein said controller changes a configuration of said UID in response to changing said location of said UID.

3. The user interface device of claim 1, wherein said at least one lighting attribute includes at least one of a preset, brightness, color, saturation, direction, beam width and spot size.

4. The user interface device of claim 1, further comprising a transceiver which transmits the UID signal to said one or more light sources of said one or more lighting systems.

5. The user interface device of claim 1, further comprising a transceiver which emits the UID signal to communicate with said one or more light sources of said one or more lighting systems, said one or more light sources providing said UID with identifying information unique to different one of said one or more light sources or to different sets of said one or more light sources.

6. The user interface device of claim 5, wherein said location is determined by measuring strengths of signals including said identifying information and measuring time of flight of said signals.

7. The user interface device of claim 1, wherein said controller determines a location of said nearest light source by comparing information received from a plurality of light sources of said lighting systems.

8. The user interface device of claim 1, further comprising a memory that stores different presets associated with different light sources of said one or more lighting systems or to different sets of said light sources.

9. A method in a user interface device (UID) for controlling lighting systems having one or more light sources, wherein said method comprises:

determining a location of the UID in relation to said one or more lighting systems based on information carried in one or more signals emitted by the one or more light sources, said one or more light sources measures at least one of strength and time of flight of a UID signal from said UID and sends said measured at least one of strength and time of flight of said UID signal to the UID which determines said location of the UID, wherein the one or more light sources communicate wirelessly with the UID;

determining at least a nearest light source of said lighting systems relative to said location of said UID; and

controlling at least one lighting attribute of said nearest light source in accordance with said location based on parameters, presets or modes of operation associated with the nearest light source or with a corresponding group of light sources including the nearest light source.

10. The method of claim 9, further comprising changing a configuration of said UID in response to changing said location of said UID.

11. The method of claim 9, further comprising:

transmitting the UID signal from a transceiver in said UID to a plurality of light sources of said lighting systems.

12. The method of claim 9, further comprising displaying a map of a local area, said map including at least one of an indication of said location of said UID and positions of said one or more light sources.
