A method for the continuous preparation of electroluminescent lamps comprises (1) coating a strip of metal foil e.g. a 0.001-0.01 inch sheet of aluminium, with a 0.0005-0.002 inch layer of dielectric, e.g. barium titanate dispersed 10-50% in an organic resin e.g. cyano-ethylcellulose, and then with a 0.0005-0.003 inch layer of phosphor, e.g. copper-activated zinc sulphide, similarly dispersed; (2) passing the phosphor-coated strip and a strip of conductive glass paper through a roller nip, to bond the glass paper to the phosphor, and then preferably (3) heat-pressing a sheet of low-melting plastic e.g. nylon, on to the crushed glass surface, so that the plastic flows through the interstices of the glass paper and bonds to the organic dispersion resin. Alternatively, the low-melting plastic may be joined to the conductive glass strip by heating rollers prior to the bonding of the glass to the phosphor. The whole strip may then be sheated in ClF3 or Cl2F2 ethylene. A copper ribbon electrode may be included between the glass and the nylon. |
