At realization of a light source the glass plate coated with ІТО layer and a layer of phosphorus on an internal surface was as the anode. It serves as an element which develops light. The optimization of electron field emission parameters in dependence on the technological conditions of nanostructured carbon film cathode deposition was performed. The nanostructured carbon film was deposited by electron-bean sputtering of graphite on metal or silicon with the catalyst (Fe, N і) substrates. Because the offered light source does not require thermal power, owing to use of the cold cathode, it provides high efficiency of light comparative with light-emitting diodes. Also expected long life time owing to more reliable structure is important. Predicted life time > 8000 hoursdoes a light source on the basis of carbon nanostructured films and nanotubes commercially viable. Thus, as a result of performance of the project the prototypes of a light source on the basis of carbon nanostructured films as the cold (field emission) cathodes are developed. Parameters of the economical light sources will provide significant saving of energy. Product Description popup.authors popup.nrat_date 2020-04-02 Close
