ALTERNATING CURRENT HID LAMP WITH MAGNETIC DEFLECTION

A magnetic field controller has been developed, which allows magnetic deflection of the arc of an alternating current high intensity discharge (HID) lamp. The controller consists of a driving circuit and an electromagnet. The system delivers a fast switching magnetic field, which can follow the alternating current signal of an alternating current HID ballast. The method minimizes the electromagnet's inductance and uses fast reacting ferromagnetic materials (Ni-Zn ferrite). To achieve the required magnetic field, a current amplifier was developed to pick up the signal from the alternating current ballast and drive the electromagnet with up to two amperes. The alternating magnetically deflected HID lamp system allows the use of magnetic deflection for alternating current HID lamps. A vehicle headlamp system can achieve multiple beam functions (day light running, low beam and high beam) of a headlight system with only one alternating current lamp.

AC HIGH LUMINANCE DISCHARGELAMP WITH MAGNETIC DEFLECTION

PROBLEM TO BE SOLVED: To provide a high beam and a low beam by receiving a power signal and imparting an AC electromagnet power in order to drive an electromagnet in respect to an AC lamp current. SOLUTION: A lamp control device 16 or a ballast drives a lamp for a proper light output. Although it is easy to adapt a magnetic control to the operating frequency of the ballast as the operating frequency is lower, a discharge lamp with low operating frequency weakens the influence of arc more, and a low- pressure lamp particularly does so. The more diffused arc tends to impart the weaker light projection. A preferable lamp ballast cuts a direct current of about 12 B reaching an AC signal from a vehicle battery. Thus, the cut AC signal of 12 V is converted to a lamp operating voltage. Preferably, the lamp control device 16 outputs a rectangular wave signal and has an operating frequency of about 400 Hz. Since the arc response time is delayed in a high- pressure lamp, the necessity of closely ...
