Abstract

A serpentine core 10 of opaque material is used as a baffle to confine light from neon lamps 12, 14, 16 and 18 to respective associated photoconductors 12', 15', 16' and 18' deposited on slides 20, 20. Core 10 also serves as a spacer between slides 20, 20.

Photosensitive Device Packaging

A serpentine core 10 of opaque material is used as a baffle to confine light from neon lamps 12, 14, 16 and 18 to respective associated photoconductors 12', 15', 16' and 18' deposited on slides 20, 20. Core 10 also serves as a spacer between slides 20, 20.

Core 10, if made of metal, also serves as an external electrode in a circuit for field ionizing the neon lamps, including one of the internal electrodes of each of the lamps. An alternating potential of 750 volts at a frequency of between 1000 and 60 cycles per second serves to ionize the NE2H neon lamps.

A core 10 of good heat conducting material, such as aluminum, serves to convey away heat that would otherwise adversely affect the circuit components.
