Abstract: The invention relates to an intelligent lamp or an intelligent contact terminal for a lamp, which can be used in a lighting system comprising a plurality of individually controlled lamps (1; 5) linked in a common power-supply circuit (8, 9) and an operation control device for transmitting a desired operation control signal to electronic control elements (11, 12, 13), associated with the lamp or the contact terminal and reacting or failing to react selectively to various control signals. Together with the lamp or its contact terminal, said electronic control elements (11, 12, 13) provide a single replaceable component which, on the basis of a message included in the operation control signal, identifies itself to serve as an appropriate lamp. In addition, the electronic control elements (2; 6) monitor the condition of itself and that of the lamp and, if necessary, produce a fault indication.
