MINIATURE PHOTOFLASH UNIT WITH ENCAPSULATED FLASH LAMPS

摘要

TITLE: MINATURE PHOTOFLASH UNIT WITH ENCAPSULATED FLASH LAMPS A miniature photoflash unit which is electrically activated when the unit is electrically connected to a power source (piezoelectric crystal) associated with many of today's pocket type cameras. The unit is capable of being positioned atop the camera and comprises a small planar housing, lamp-firing circuitry positioned externally of the housing, several (e.g., ten) subminiature flash lamps secured to the base and having lead-in wires passing through the base to effect electrical contact with the lamp-firing circuitry, a tabular mounting device is inserted within the camera to provide electrical connection between the circuitry and power source, and means for covering the externally located lamp-firing circuitry. The circuitry may be positi??ed either on an external surface of the housing or on a planar surface of the cover means which is attached to the housing.
