Title:
【発明の名称】電界放出用陰極および電界放出用陰極を含む光源
Document Type and Number:
Japanese Patent JP2002504260
Kind Code:
A
Abstract:
A field emission cathode (40) includes field emitting bodies (42) in the form of fibers, and a base body having a longitudinally extending core (41) formed by at least two wires (43) between which the fibers are secured. The fibers are distributed along at least a part of the length of the core (41) and extend radially outwards from the core. A light source (10) includes an evacuated container having walls at least a portion of which consists of an outer glass layer (23) on which at least a major part thereof is coated on the inside with a layer of phosphor (24) forming a luminescent layer, and a conductive layer forming an anode (25). The layer of phosphor (24) is excited to luminescence by electron bombardment from a field emission cathode (40) located in the interior of the container, and a modulator electrode or grid (30) is arranged between the cathode (40) and the anode (25) for creating an electric field for the emission of electrons. The field emission cathode (40) includes field emitting bodies (42) in the form of fibers, and a base body having a longitudinally extending core (41) formed by at least two wires (43) between which the fibers are secured.
