PHOTOFLASH LAMP-REFLECTOR MODULE AND MINIATURE MULTIFLASH UNITS FOR PHOTOGRAPHIC CAMERAS

摘要

A tubular photoflash lamp that has a volume less than 0.6 cc and contains hafnium fuel is combined with a reflector that has a maximum width opening which is from about 1.2 to 2 times the lamp diameter to provide a miniaturized lamp-reflector module that has a light output that substantially matches or exceeds that obtained from the larger lamp-reflector modules used in conventional flashcubes (475 zonal lumen-seconds). Selected numbers of the novel lamp-reflector modules are grouped together in various geometrical arrays to provide miniature flashcubes and miniature rectangular or cylindrical-shaped multiflash units having dimensions that conform more closely with those of the compact automatic cameras now being marketed.
