An identification system for a light radiation source (103) having a control circuit (107) for communicating with an identification circuit (108) associated with the light radiation source, wherein the identification circuit is arranged for storing data relating to the light radiation source. During operation, the control circuit communicates with the identification circuit via a signal path comprising at least a portion of a first electric wire (112) provided for energizing the light radiation source such that it is used as a first transmitting antenna for communicating with the identification circuit. The operation of the light radiation source is controlled in dependence on the data retrieved from the identification circuit. Depending on the result of the identification, operation of the light radiation source can be authorized or prevented, thus blocking the use of an incorrect radiation source for a given application.
