LIGHT SOURCE Russian patent published in 2013 - IPC H01J63/00 B82Y99/00 

FIELD: physics.

SUBSTANCE: in a light source, having a vacuum envelope inside of which there are cathodic electrodes in form of extended surfaces, having an emitter layer in form of a coating of nano-sized current-conducting structures and anodic electrodes having a phosphor layer, the emitter layer is in form of a heterogeneous structure in which there are additional electrostatic field concentrators in form of a set of nano-sized and/or micro-sized dielectric structures, wherein there are nano-sized gaps between the surfaces of the nano-sized current-conducting structures and the nano-sized dielectric structures.

EFFECT: providing activation of existing and formation of additional autoemission centres on conducting nano-structured particles of the emitter layer, reduced intensity of loading emitting nano-sized structures, eliminating criticality of the autoemission structure of the light source to the dimensional scatter of the nano-sized current-conducting structures and improved consumer properties of the light source, simplification of technological processes of making said light source.
