Abstract
In various embodiments, a lighting system is provided. The lighting system includes at least two visual light communication units (VLC units), and at least one effect luminaire, at which one of the VLC units is provided. The further VLC unit is arrangeable at an object. At least one item of state information of at least one of the object or the effect luminaire is transferable between the VLC units by at least one light signal.
Claims13
A lighting system, comprising:
- at least two visual light communication units (VLC units);
- at least one effect luminaire, at which one of the VLC units is provided,
- wherein a further VLC unit is arrangeable at an object,
- wherein at least one item of state information of at least one of the object or the effect luminaire is transferable between the VLC units by at least one light signal,
- wherein the state information is at least one of a position data of the object or an operating state of a controllable element of the object or a position data of the effect luminaire or an orientation of the effect luminaire in space or an operating state of one or more controllable light sources;
- and
- an evaluation unit configured to correlate a detected position data of the object detected by one of at least two sensor units with a detected position data of the object detected by another of the at least two sensor units.
A method for transferring or for exchanging at least one item of state information from at least one of at least one object or at least one effect luminaire of a lighting system, the lighting system comprising:
- at least two visual light communication units (VLC units);
- at least one effect luminaire, at which one of the VLC units is provided,
- wherein the further VLC unit is arrangeable at an object, wherein at least one item of state information of at least one of the object or the effect luminaire is transferable between the VLC units by at least one light signal, wherein the state information is at least one of a position data of the object or an operating state of a controllable element of the object or a position data of the effect luminaire or an orientation of the effect luminaire in space or an operating state of one or more controllable light sources;
- and
- an evaluation unit configured to correlate a detected position data of the object detected by one of at least two sensor units with a detected position data of the object detected by another of the at least two sensor units,
- the method comprising:
- detecting the state information of at least one of the object or of the effect luminaire;
- at least one of modulating or encoding the items of state information into a light signal;
- transmitting or emitting the light signal by a first VLC unit;
- receiving the light signal by a second VLC unit;
- and
- at least one of decoding or processing the state information.
