Abstract
A multilamp photoflash array with lamp-reflector units in linear rows facing in opposite directions and nested back-to-back. The rows of reflectors for both sides of the array are vacuum-formed from a single sheet web between the reflector rows for providing a spring-hinged center support. Each reflector has a parabolic surface with an elongated cylindrical recess behind its associated tubular lamp whereby an air space is provided between the reflector and lamp which functions as a thermal insulator for minimizing heat distortion of adjacent reflectors upon flashing of the lamp.
