ABSTRACT:
A disk-shaped flashlamp unit for use within an indexing means or mechanism associated with a camera. The unit includes several, e.g. ten, electrically-activated flashlamps radially disposed within the unit's plastic, light-transmitting housing. A pair of planar reflectors are utilized for each lamp to reflect the light therefrom through the housing. Light output can be further enhanced by utilization of two additional planar reflective members adjacent each lamp, the four members surrounding the side and bottom portions of the flashlamp's envelope to thereby direct light emitted from the flashlamp in a substantially singular direction through the peripheral region of the plastic housing. The invention's reflectors also assure prevention of sympathetic ignition.
