ILLUMINANTS EQUIPPED WITH POWERFUL XENON LAMPS
ARMY ENGINEER RESEARCH AND DEVELOPMENT LABS FORT BELVOIR VA
Pagination or Media Count:
Experimental and theoretical investigations of mirror illuminants for high-powered xenon lamps were made. It was found that the material for the reflector must have a reflective coefficient of not less than 0.65. The material of the mirror reflector and the flat inserts must also be corrosion resistant and must be able to withstand high temperatures up to 300 deg C. In the design of illuminants, the problem of cleaning, and restoring the mirror properties of the reflector during operation must be taken into account. It is recommended that screens be made of ordinary steel without luminescent covering and that reinforcements be provided against buckling. The illuminant must be equipped with a spare lamp that switches on automatically when the original lamp burns out. The light aperture under the lamp must be covered by a protective screen that furnished protection against splinters should the lamp break. The design of a single beam illuminant must provide for its rotation both around the vertical axis support tower and relative to the axis of the lamp. To reduce the danger of the reflectors buckling, it must be made of individual sheets whose one dimension must be equal to the length of the profile curve, and the other - not more than 500 mm.
