Abstract
A photoflash unit comprising a horizontal linear array of flashlamps enclosed within a one-piece housing member having a light-transmitting front portion folded over a back portion containing a plurality of lamp-receiving cavities in which respective lamps are disposed. The housing is a formed sheet of plastic film having a linear fold disposed horizontally along the top of the array of cavities, which are selectively aluminized to provide a reflective coating on the cavity surfaces. A pair of lead-in wires from each of the lamps are connected to conductive circuit patterns on one side of a printed circuit board sandwiched between a set of tabs which run along the bottom of the front and back portions of the housing and are secured together. The sides of the housing are also secured so that the lamps, lead-in wires and connections are disposed within a secured enclosure, with a plurality of conductive connector terminals being disposed on a tab which projects from the printed circuit board and extends exteriorly of the secured enclosure.
