Electrode for high-voltage fluorescent tube, has cup-like or tubular electrode body partially carrying electron emitter material, and partially formed from wire gauze, where wire gauze is made of soft iron

摘要

The electrode has a cup-like or tubular electrode body (1) partially carrying an electron emitter material (3). The electrode body is partially formed from a wire gauze. The wire gauze is made of soft iron. An aperture size of the wire gauze ranges from 100 micrometers to 300 micrometers. A wire gauge of the wire gauze is in range of 50 micrometers to 200 micrometers.
