Sealed Beam Integrated Reflector Searchlight.

Abstract

A program has been completed providing a feasibility searchlight with power supply, remote control box and connecting cables. The searchlight has an overall length of 25 inches, is approximately 6-3/8 inches in diameter and weighs less than 50 lbs. The unit features a sealed beam integral reflector, 1 KW, xenon short arc lamp. Other features include a self contained cooling fan, a beam elevation control (+20 deg to -10 deg), a running time meter, a transverse adjustment for the light stop aperture, and a braking mechanism to hold the beam elevation rotating cyclinder in place when the searchlight is not in use. The searchlight system has been tested and operated in an actual armored vehicle environment. The infrared mode was checked by placing a filter at the output of the searchlight. The searchlight performed well in both the IR and visible modes. The most significant features of this searchlight are its compact size, the ability to mount the searchlight under armor and the clean beam (sharp cut-off) which leads to the absence of backscatter.
