A method of controlling a lighting system includes a learning procedure. The lighting system includes lighting modules and a controlling device. The lighting modules are arbitrarily arranged, and each lighting module can communicate with neighboring lighting modules via communication units arranged at sides of the lighting module. The learning procedure defines a lighting module arrangement and a communication network for communication between the controlling device and the lighting modules. During the learning procedure, a token is forwarded from one lighting module to another lighting module, while ensuring that all lighting modules are visited by the token. Further, geometric information about how the lighting modules are arranged in relation to each other is generated.

1. A method of controlling a lighting system that comprises lighting modules and a controlling device, which are configured to communicate with each other, wherein said lighting modules are arbitrarily arranged in an arrangement and each lighting module is configured to communicate with neighboring lighting modules via communication units arranged at several sides of the lighting module, the method comprising the act of: connecting the controlling device to a first communication unit of a first lighting module of the lighting modules, the first communication unit being at a first side of the first lighting module;connecting a second communication unit of the first lighting module to the arrangement through a second lighting module of the lighting modules, wherein the second communication unit is at a second side of the first lighting module, the first communication unit being different from the second communication unit, and the first side being different from the second side; performing a learning procedure for defining a lighting module arrangement and a communication network for communication between the controlling device and the lighting modules;wherein the learning procedure comprises the acts of: forwarding a token from one lighting module to another lighting module, while ensuring that all the lighting modules are visited by the token; andconcurrently providing geometric information about how the lighting modules are arranged in relation to each other. 2. The method according to claim 1, wherein said token carries an address which is assigned to a receiving lighting module at a first visit of the token to that the receiving lighting module, and wherein said address is updated at the token after each assignment. 3. The method according to claim 1, wherein said act of concurrently providing geometric information comprises determining in what direction the token is to leave a lighting module, and communicating direction information about said direction to the controlling device. 4. The method according to claim 3, wherein said controlling device determines a size and a shape of the lighting module arrangement using said direction information. 5. The method according to claim 3, wherein said act of concurrently providing geometric information further comprises communicating direction information to a next lighting module which the token is to visit next. 6. The method according to claim 5, wherein said learning procedure further comprises the act of determining a rotation correction of a default orientation of a lighting module at reception therein of said direction information. 7. The method according to claim 1, wherein said learning procedure further comprises the act of storing, at each lighting module, information about at which side of a visited lighting module said token was received at a first visit to the visited lighting module. 8. The method according to claim 1, wherein said lighting modules are in one of at least two different states, including an idle state in which said lighting modules are ready to receive communication from any side, and an active state in which said lighting modules send communication in at least one direction. 9. The method according to claim 1, further comprising the act of performing an optimization procedure for optimizing said communication network, said optimization procedure configuring at least one optimized data path through said lighting module arrangement, for sending data from said controlling device to said lighting modules. 10. The method according to claim 9, wherein said controlling device determines said at least one optimized data path based on knowledge about said lighting module arrangement. 11. The method according to claim 10, wherein a data path is defined as a unidirectional path by said controlling device sending communication control data to each lighting module, to be included in the data path, wherein said communication control data defines at least one of the communication units of the lighting module to receive data only, and at least one of the communication units of the lighting module to send data only. 12. The method according to claim 1, further comprising the acts of detecting an amendment of said arrangement and adapting control of the lighting modules accordingly. 13. The method of claim 1, further comprising the act of, while the token is moving throughout the arrangement, converting a trace of the token from one lighting module to another lighting module into a unidirectional return data path back to the controlling device. 14. The method of claim 1, further comprising the acts of: sending a presence inquiry to the one lighting module from an inquiring lighting module; andsending a reply to the inquiring lighting module from only a side of the inquiring lighting module where the presence inquiry was received. 15. The method of claim 1, further comprising the acts of: sending presence inquiries from sides of an inquiring lighting module to its neighbors to determine a result including the sides that the neighbors exist;determining that a neighbor lighting module exists at a side of the inquiring lighting module if a reply to a presence inquiry from the side is received;storing the result by the inquiring lighting module; andrepeating the acts of sending, determining and storing for each of the lighting modules. 16. A lighting system comprising, lighting modules, wherein each of the lighting modules comprises at least one communication unit; anda controlling device for controlling the lighting modules,wherein the controlling device is connected to a first communication unit of a first lighting module of the lighting modules, the first communication unit being at a first side of the first lighting module, and a second communication unit of the first lighting module is connected to the arrangement through a second lighting module of the lighting modules, wherein the second communication unit is at a second side of the first lighting module, the first communication unit being different from the second communication unit, and the first side being different from the second side,wherein said lighting modules are arbitrarily arranged and each lighting module is configured to communicate with neighboring lighting modules via communication units arranged at several sides of the lighting module,wherein the lighting system is configured to be self-learning regarding the arrangement thereof,wherein the lighting system is configured to define said arrangement and a communication network for communication between the controlling device and the lighting modules,wherein the lighting system is configured to forward a token from one lighting module to another lighting module while ensuring that all the lighting modules are visited by the token, and to concurrently provide geometric information about how the lighting modules are arranged in relation to each other. 17. The lighting system according to claim 16, wherein said controlling device is arranged to detect changes of said arrangement and adapt the control of the lighting modules accordingly. 18. The lighting system according to claim 16, wherein each lighting module comprises a storage for storing information regarding which side of a receiving lighting module said token was received at a first visit to the receiving lighting module. 19. The lighting system of claim 16, wherein the lighting system in configured to, while the token is moving throughout the arrangement, convert a trace of the token from one lighting module to another lighting module into a unidirectional return data path back to the controlling device. 20. The lighting system of claim 16, wherein each of the lighting modules is configured to detect neighboring lighting modules by: sending presence inquiries from sides of an inquiring lighting module to its neighbors to determine a result including the sides that the neighbors exist;determining that a neighbor lighting module exists at a side of the inquiring lighting module if a reply to a presence inquiry from the side is received; andstoring the result by the inquiring lighting module.
