Abstract: A hand held search light includes a miniaturized electronic control circuit for igniting and operating an arc lamp in the light. A lamp mounting arrangement is disclosed for shock mounting the arc lamp, including arrangement to center and focus the light beam emitted by the search light. The search light is modularized for ease of field maintenance by unskilled personnel.

Abstract: A miniaturized electronic control circuit and method for igniting and controlling the operation of an arc lamp in a hand held search light is disclosed. A modulator provides output pulses at a variable duty cycle to a switched regulator which provides an output voltage to a first electrode of the arc lamp. The magnitude of the output voltage of the regulator varies in accordance with the duty cycle of the output pulses from the modulator. A lamp igniter is coupled between a first control input to the modulator and a second electrode of the arc lamp. The lamp igniter, in response to a first magnitude in the output voltage from the switched regulator, effects the generation of a high voltage pulse to ignite the arc lamp.
