during nighttime hours as compared to that provided by electroluminescent wire illumination solely the electroluminescent wire is made from a copper wire which is surrounded by an electophosphoric dielectric material such as doped zinc sulfide and a second set of electrodes are placed on the outer surface of the dielectric since the dielectric medium is susceptible to moisture damage two layers of polymeric coaxial tubes are provided to encase the electroluminescent wire the wire is sold in long continuous lengths by lytec and is manufactured by elam electroluminescent industries ltd jerusalem ill a required length of the electroluminescent wire is cut and one end of the wire is stripped to expose the central copper wire and the copper wire surrounding the dielectric these two wires are attached to corresponding two terminals in the power supply after the connection is made the end of the electroluminescence wire is sealed by shrinkable tubing or other means to prevent moisture damage and or short circuit the portable power supply accepts batteries of various sizes and converts the dc battery voltage to a ac voltage and transforms it to a ac voltage in the range of 100 to 120 the frequency of the ac voltage can be in the range of 60 hz to 6 kilohz the current levels delivered by the power supply is typically small less than 100 milliamps thereby minimizing or eliminating any.
