LIGHT SOURCE FOR MOTOR VEHICLES

摘要

Light for motor vehicles and the like provided with a lighting device comprising a pair of power supply lines flowed through by a primary supplying current, two or more lighting branches each comprising one or more light sources adapted for being flowed through by a secondary supplying current; and an electronic control circuit configured to determine the secondary current flowing through each lighting branch; limit the primary supplying current to a predetermined minimum value when the secondary current flowing through at least one of said lighting branches is lesser than a predetermined threshold current; control the simultaneous transition of the light sources from a pre-lighting state to a complete-lighting state, when each of the secondary currents flowing through the lighting branches is greater than or equal to the predetermined current threshold.
