Classification: CPC H  Y | IPC H

Claim 0:
1. A proximity-detecting device, comprising,
a signal input unit for receiving, from external originating lighting nodes, wireless identification signals comprising respective lighting-node identification information;
a signal-strength determination unit connected to the signal input unit and configured to determine a signal-strength value indicative of a received signal power amount of the identification signal of the respective originating lighting node;
a proximity-detection unit connected to the signal-strength determination unit and configured, upon determining that the received signal-strength value exceeds a predetermined proximity threshold value associated with the originating lighting node, to generate and provide a proximity-information signal indicative of the proximity-detecting device being located within a predetermined proximity area of the originating lighting node; and
a threshold-determination unit connected to the signal input unit, to the signal-strength determination unit and to the proximity-detection unit and configured, upon determining fulfilment of a pre-stored threshold-updating criterion, for updating a given proximity threshold value for a given originating lighting node, wherein the threshold-updating criterion comprises one or more updating-conditions associated with the lighting-node identification information of the received identification signals, to update the proximity threshold value for the given originating lighting node, for redefining the proximity area associated with the given originating lighting node.
