Abstract

Provided is a fluorescent discharge lamp tube comprising a glass tube (9) filled therein with a discharge substance, a pair of metal electrodes (2 and 3) sealed at the two ends of the glass tube, and a fluorescent film (10) applied to the inner face of the glass tube. The metal electrodes are coated with insulator particles (4). The fluorescent film is formed of a mixture of particles of a fluorescent material for emitting a light when irradiated with an electron beam, and particles of a fluorescent material for emitting a light when irradiated with an ultraviolet ray. This fluorescent discharge lamp tube has a long lifetime because the metal electrodes are not exposed to a discharge space. Moreover, the fluorescent discharge lamp tube is lit within 10 milliseconds when fed with a high frequency.
