ABSTRACT:
A photoflash unit comprising a plurality of 2n flashlamps attached to a printed circuit board and disposed in a linear array with the longitudinal axes of respective lamps aligned in parallel. The circuit board has a substantially rectangular portion with n spaced apart extensions projecting vertically from a longer side thereof, the extensions being located behind alternate lamps of the linear array. Each extension contains portions of circuit patterns bridged by a mass of switch material to provide a solid state radiation switch on each extension and adjacent to a respective lamp for receiving radiant energy emitted by that lamp. The unit further includes a plurality of reflector cavities within each of which a respective one of the flashlamps is nested. Each reflector cavity includes a recessed rear wall section for accommodating a circuit board extension, such that each of the extensions are disposed between a respective lamp envelope and the recessed rear wall of the associated reflector. With the lamp contiguous with an upper portion of each reflector cavity and each circuit board extension contiguous with a recessed lower portion of a respective cavity, substantially equal predetermined spacings are maintained between the switches of the n extensions and the alternate lamp envelopes associated therewith.
