Abstract
A photoflash lamp-reflector module for use in a photoflash unit having a plurality of such lamp-reflector modules arranged in a compact array. Each reflector has a substantially parabolic surface with a centrally disposed elongated cylindrical recess having a longitudinally extending central slot. The associated tubular lamp is nested within the recessed portion of the reflector, whereby an oversized lamp is accommodated by the reflector with little or no loss of light output.
