Abstract

1344652 Multi-lamp flash assemblies PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 3 Nov 1971 [6 Nov 1970] 51111/71 Heading G2A A multi-lamp photo-flash unit comprises an elongate support 2 on which two rows 3, 4 of flashbulbs are arranged, the bulbs co-operating with resting reflector members (5, 6) alternately facing in opposite directions Fig.1, (not shown) and an envelope (7) of synthetic resin surrounding these components. The bulbs are high voltage flash-bulbs connected in parallel by at least three juxtaposed connectors and they may be Piezoelectrically fired. As described, two outer connectors 26, (44) Fig.4, (not shown) are connected to one of the terminal wires 24 of then associated rows of bulbs, and two central combshaped connectors 14, 16 are connected to the other terminal wires. Guides 16, 17 are provided to screen the bulbs from the adjacent bulbs of the other row, and guides 20, 21 are provided for locating the envelope (7) which has cavities for locating the bulb tips 29. Each bulb has a fusing strip 27 associated therewith. (For Figure see next page)
