Lighting sources with a cold cathode electron tube

E. CZERWOSZ, S. WASZUK, M. SUCHANSKA, and J. KECZKOWSKA
Lighting sources with a cold cathode are widely used in electronics. The lamps with a cold cathode are used primarily as sources of white light in optical scanners, digital indicators, display panels and signalling devices. In the paper the advantages of carbonaceous materials as emitters of cold electrons and the possibilities of using them to create a cathode in an electron lamp are discussed.
Key words: 

carbonaceous cold electron cathodes, electron lamp, cold electron emission, lighting elements.
