Control device for light source e.g. headlight of vehicle, has switching transistor is conducted so that a current from current control module is transferred to vehicle lighting device when light control switch is turned on

摘要

The control device (100) has a current control module (120) that is connected to an ignition switch (110), so that a first current is transferred to vehicle light device when ignition switch is turned on. A switching transistor of a control unit (140) is connected separately to current control module and light control switch (130). The switching transistor is conducted so that a second current from current control module is transferred to vehicle lighting device when the light control switch is turned on. The second current is less than the first current.
