ABSTRACT:
In the vehicle-lamp lighting-on device, a body case has a connection opening formed in the front end thereof. A lighting-on transformer is disposed within the body case. The transformer includes a core housing with an iron core and a coil bobbin with a secondary coil wound thereon. The connection opening of the body case is shielded at the front end of the lighting-on transformer. A socket for receiving a vehicle discharge lamp includes a high-voltage terminal and low-voltage terminals. When the socket is inserted into the connection opening of the body case, the high-voltage terminal of the socket is connected to the high-voltage side terminal of the lighting-on transformer, and the low-voltage terminals are connected to the low-voltage side terminals. The connection opening of the body case is shielded by the front surface (made of insulating material) of the lighting-on transformer. The vehicle-lamp lighting-on device can be completed by merely attaching the socket to the assembly of the lighting-on transformer and the body case. Therefore, the assembly of the device is easy. Further, the height of the vehicle-lamp lighting-on device is reduced overall since there is no need to form a wall corresponding to the shielding member in the body case.
