Definitions

  • My present invention comprises an incandescent lamp of high efliciency and improved characteristics, in which light is emitted by selective radiation.
  • the cerium dioxide acts as a coloring agent, which increases the selectivity ofthe radiator for a desired range of radiation.
  • Other coloring agents may be used, for example chromium oxide.
  • Thin metallically colored bodies, as, for example, titanium nitride, may be applied upon the surface of the radiator, or dissolved in a surface layer, or, indeed, in the radiator as a whole.
  • the radiator consists of a single crystal. or of a few crystals. 1
  • FIG. 3 illustrates a plateshaped anode having a conductive frame 17 containing a transparent plate 18, on the surface of which a symbol, represented by the word Osram, has been applied by means of tungsten powder or other suitable black body radiator.
  • a black body radiatesmore light of a certain wave length than a transparent body per unit of surface, the metallic coating as represented by the word Osram will appear brighter at high temperature than the rest of the radiator.
  • An electric lamp comprising an envelope, a refractorv transparent bodyther'e- .which through the spaces in saidanode.
  • a lighting body which 18 subect to electron bombardment, constituted of one or more crystals of thorium oxide.
