A basic idea of the invention is to configure lighting in a network of lamps in that a lamp of the network adjusts its light emission depending on presence detection in its own direct environment and the presence detected in the environment of other lamps of the network. An embodiment of the invention relates to a system (10) for automatically configuring a lighting, wherein the system comprises a network of lamps (12), in which every lamp is coupled to a presence detector (14) and can receive signals from other lamps in the network, wherein a received signal indicates an activity detected by the presence detector coupled to the lamp, which transmits the signal, and wherein every lamp adjusts its light emission depending on the signal received from other lamps and the measurement of its presence detector. The invention allows automatically configuring a lighting with a network of lamps for a certain area in that lights go on before a person gets to a certain area. ## Claims ### Claim 1 A system for automatically configuring lighting parameters, the system comprising a network of lamps coupled to a presence detector, each lamp being configured to receive signals from other lamps in the network, wherein a received signal indicates an activity detected by the presence detector coupled to the lamp, which transmits the signal, and wherein every lamp adjusts its light emission depending on the signal received from other lamps and the measurement of its presence detector, and wherein each lamp is configured to adjust its light emission by performing the acts of receiving as inputs activity levels from the other lamps and the measurement of its presence detector, processing the received inputs, and adjusting the light emission depending on the processing. ### Claim 2 (depends on 1) The system of claim 1, wherein a received activity level from another lamp comprises the history of activities detected by the presence detector coupled to this lamp, the processing of the received inputs comprises a learning from the history of activities detected by presence detectors in order to determine the movement of a person, and the light emission is adjusted based on the determined movement of a person. ### Claim 3 (depends on 1) The system of claim 1, wherein the processing of the received inputs comprises processing the inputs with a weight function, wherein every input is weighted and the used weights are adjusted continuously depending on the activity detected by one or more presence detectors. ### Claim 4 (depends on 3) The system of claim 3, wherein the adjusting of the weights depending on the activity detected by one or more presence detectors comprises increasing the weights of two or more lamps if the presence detectors coupled to these lamps detect activity within a predetermined time span and/or if the activity levels of these lamps follow the same pattern, otherwise decreasing the weights of two or more lamps. ### Claim 5 (depends on 3) The system of claim 3, wherein the function used for processing the inputs further comprises a time delay by using only or additionally activations of lamps which are a predetermined step back in time. ### Claim 6 (depends on 1) The system of claim 1, wherein the processing of the received inputs comprises processing the inputs with a sigmoid function, a radial basis function or a softmax activation function. ### Claim 7 A lamp comprising a light source, a communication unit for creating network connections and communicating with other lamps, a presence detector, a memory storing a configuration of the lamp and a program for controlling the activity of the lamp depending on inputs received from other lamps and on measurements of the presence detector, and a processing unit for executing the program stored in the memory, wherein the processing unit adjusts a light emission of the light source in response of receiving, by the communication unit, as inputs activity levels from the other lamps and the measurement of its presence detector by processing the received inputs and the measurement of the presence detector and by adjusting the light emission depending on the processing. ### Claim 8 A method for automatically configuring a lighting in a network of lamps, comprising the following acts: receiving signals from other lamps in the network, wherein a received signal indicates an activity detected by a presence detector coupled to the lamp, which transmits the signal, receiving a measurement of a presence detector coupled to said lamp, and adjusting the light emission of said lamp depending on the signals received from the other lamps and the measurement of the presence detector coupled to said lamp, wherein the received signals contain activity levels from said lamps and the light emission of the lamp is adjusted depending on a processing of the activity levels and the measurement of the presence detector as inputs. ### Claim 9 (depends on 8) The method of claim 8, wherein a received activity level from another lamps comprises the history of activities detected by the presence detector coupled to this lamp, the processing of the received inputs comprises a learning from the history of activities detected by presence detectors in order to determine the movement of a person, and the light emission is adjusted based on the determined movement of a person. ### Claim 10 (depends on 9) The method of claim 9, wherein the adjusting of the weights depending on the activity detected by one or more presence detectors comprises increasing the weights of said lamps if the presence detectors coupled to these lamps detect activity within a predetermined time span and/or if the activity levels of said lamps follow the same pattern, otherwise decreasing the weights of said lamps. ### Claim 11 (depends on 8) The method of claim 8, wherein the processing of the inputs comprises processing the inputs with a weight function, wherein every input is weighted

received inputs comprises processing the inputs with a sigmoid function, a radial basis function or a softmax activation function, and/or wherein the function used for processing the inputs further comprises a time delay by using only or additionally activations of lamps which are a predetermined step back in time.
