Abstract: |
The invention provides a field emission illuminating light source in the field of daylight illumination light source technology. It comprises: a transparent ball type hollow casing with an anode layer and fluorescent material coated on the surface, wherein the casing inner part is vacuum sealed and it arranges a cathode filament with nanometer electron ejector on the surface on the center of the casing; the anode layer and the cathode filament are connected with the anode electrode and the cathode electrode by wire. The cathode filament adopts mental wire to reel into bending sharp so as to provide more effective electrode ejecting point. It can also comprise the cushion structure to reduce the field emission voltage. |
