Intelligent lamp or intelligent contact terminal for a lamp
First Claim
1. An intelligent contact terminal for a lamp for use in a lighting system of a vehicle, comprising:
- a plurality of individually controlled replaceable lamps linked in a common power-supply circuit having insulated conductors, each of said lamps being connected to an intelligent contact terminal and associated electronic control elements;
at least one common code conductor which is connected to each of said electronic control elements;
an operation control device for transmitting a desired identification code signal over said at least one common code conductor to the electronic control elements associated with each contact terminal, said elements selectively reacting or failing to react to various identification code signals;
wherein each replaceable contact terminal has connecting studs pressed into contact with said conductors through the insulation thereof, said electronic control elements including means for identifying a predetermined identification code included in the identification code signal, means for switching on the lamp upon identification of said predetermined identification code, means for monitoring the operating condition of the lamp and means for giving a fault indication if the current passing through the lamp is higher or lower than a predetermined maximum or minimum value; and
wherein the intelligent contact terminal has additional coding means for locally defining each lamp to operate as a particular lamp according to its location.

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.
