摘要
The present invention provides a method for using electrodeless high-intensity discharge (HID) lamps for automotive headlamp and similar applications requiring high/low beam operation (first and second beam orientation) of signaling. The HID lamp is excited with a high-frequency radio frequency (rf) signal. Modulation of the radio frequency signal is used to cause the arc of the HID lamp to selectively operate at an acoustic resonance point. At such a point, the arc undergoes a perturbation and is physically displaced from its quiescent position. When the lamp is placed at a focal or light-gathering point of an optical system having forward gain, displacement of the arc away from the focal point causes discernible changes in the farfield output of the optical system.
