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 provide structural rigidity, the cover has rectangular corner posts at each end and a transverse web at the center which engage slots in the housing and are secured by ultrasonic welding. The longitudinal edges are secured by a plurality of cylindrical posts along each side of the cover which fit into matching holes in the housing and have rivet heads formed on the ends as provided by ultrasonic heating and pressure.
