Abstract
The utility model discloses a power supply input circuit for a vehicle lamp, which comprises a plug connector J, a filtering module, a brake lamp module, a position lamp module and a steering lamp module, the filtering module is connected with the plug connector J, the brake lamp module, the position lamp module and the steering lamp module are all connected with the plug connector J, and the position lamp module is connected with the steering lamp module. The brake lamp module, the position lamp module and the steering lamp module are all connected with the filtering module, the brake lamp module is connected with a brake lamp, the position lamp module is connected with a position lamp, and the steering lamp module is connected with a steering lamp. The brake lamp, the position lamp and the steering lamp share the same filtering module, compared with a circuit connection mode that the brake lamp, the position lamp and the steering lamp independently use the filtering module, the mode is simple in structure and convenient to operate, a vehicle lamp power input circuit can be optimized, the production cost of the whole circuit can be reduced, and meanwhile the service life of the vehicle lamp is prolonged. The EMC risk of the whole power input circuit can be reduced, and the PCB layout of the whole power input circuit can be simpler.
