Fluorescent lamp and methods for making electrode assemblies for fluorescent lamps |
摘要 |
A fluorescent lamp comprises a glass tubular body defining a discharge space, and first and second electrode assemblies mounted in the discharge space in opposition to each other, each of the electrode assemblies comprising a first electrode and a second electrode. Each of the first electrodes comprises a metal lead wire with an electron-emitting material disposed on a free end thereof, and each of the second electrodes comprises a cup-shaped tube coaxially surrounding one of the first electrodes and the electron-emitting material disposed on the first electrode. The second electrode tube and the electron emitting material therein form an annular gap therebetween.
