Abstract:
1. A control circuit for a module for controlling at least two light sources in particular for a vehicle, said module comprising at least two functions (A, B) each implemented with the at least two light sources passed through by an electric current whose average intensity is different depending on said at least two functions (A, B), said control circuit comprising: a power supply input for a power source for said at least two light sources; a connection of said at least two light sources in parallel to said power supply input and to a ground; and a monitoring unit for monitoring the intensity of the current passing through said at least two light sources, said monitoring unit being arranged electrically between said at least two light sources and said ground; wherein said at least two functions (A,B) each comprises a light function or a signaling function; wherein said monitoring unit comprises a first input for a control signal for the first function (A) and a second input for a control signal for the second function (B); wherein said at least two light sources are connected with said monitoring unit so as to form at least two parallel sections for the first and the second functions (A,B), said at least two parallel sections being connected separately with said monitoring unit, said monitoring unit being able to detect a current flow fault in each section and, if a fault is detected in one of said at least two parallel sections during the first function, configured to keep the remaining section or sections active in the presence of said first function and if the fault is detected in one of said at least two parallel sections during the second function, configured to deactivate all the remaining sections in the presence of said second function.
