Abstract
A multi-functional high intensity discharge automobile headlamp features a circuit board installed within a system control box. The circuit board comprise a circuit for automatic detection and protection so that the voltages of the near lights and far lights can be determined and correctly switched, a circuit for DC/DC conversion connected to a far/near light switch and a DC/AC voltage regulator so that the voltages necessary for the near or far lights can be supplied, a circuit for voltage regulation and high-voltage starting so that the high-voltage power can be suitably controlled, a circuit for near light high-voltage control, a circuit for far light high-voltage control and a DC/AC voltage regulator for providing a low-frequency, square-wave, AC signal for voltage regulation.
