1. A multi-functional high intensity discharge automobile headlamp, comprising:

  • a circuit for automatic detection and protection, said circuit for automatic detection and protection identifying and switching between a far-light voltage and a near-light signal;

    a circuit for DC/DC conversion connected with said circuit for automatic detection and protection, said circuit for DC/DC conversion being connected to a far light and near light switch for increasing said voltage to either a far-light voltage value or a near-light value;

    a circuit for voltage regulation and high-voltage starting connected with said circuit for DC/DC conversion, said circuit for voltage regulation and high-voltage starting controlling and restricting a high-voltage power according to a predetermined power;

    a circuit for near light high-voltage control connected with said circuit for voltage regulation and high-voltage starting and to said near light and far light switch, said circuit for near light high-voltage control further sending a desired voltage value for a corresponding light bulb and being capable of detecting an anomaly in said near-light bulb and feeding back to said circuit for automatic detection and protection and notifying said circuit for DC/DC conversion to stop supplying power;

    a circuit for far light high-voltage control connected with said circuit for voltage regulation and high-voltage starting and to said near light and far light switch, said circuit for far light high-voltage control further sending a desired voltage value for a corresponding light bulb and being capable of detecting an anomaly in said far-light bulb and feeding back to said circuit for automatic detection and protection and notifying said circuit for DC/DC conversion to stop supplying power; and

    a DC/AC voltage regulator connected with said circuit for DC/DC conversion, said C/AC voltage regulator providing a low-frequency square-wave signal that facilitates the control of a light-bulb operation.
