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 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. The bottom periphery of the housing is secured together by means of a plurality of staples having legs which extend through the front and back tabs of the circuit board and are clinched onto the exterior surface of the front tab. The front portion of the housing includes a window area which lies in a plane offset from the front tab and joined thereto by a web. A label comprising an adhesive-backed sheet of substantially opaque material is affixed to the front portion of the housing and disposed to cover both the staples and the web, the web covering providing selective shielding of light radiated from flashing lamps. The back of the label can be reflective for redirecting shielded light toward the reflective cavities behind the lamps for subsequent redirection as usable light.
