ABSTRACT:
A photoflash unit comprising a linear array of flashlamps mounted on a printed circuit strip disposed within the longitudinal channel of an elongated housing member. A light-transmitting cover panel is attached to the housing member for enclosing the flashlamps. To prevent sympathetic ignition of adjacent lamps, the one-piece cover is molded to have integrally projecting transverse webs which function as light-attenuating partitions between respective pairs of lamps. In addition, the webs bridge the housing channel to provide structural rigidity.
