COLD CATHODE DISCHARGE LAMP AND METHOD OF MANUFACTURING THE DISCHARGE LAMP

摘要

A cold cathode discharge lamp capable of being rapidly started even in such a dark place that an ambient illuminance is 0.1 lux or below, comprising electrodes (5a) installed at both end parts of a glass tube (2) having a fluorescent body layer (3) formed on the inner surface thereof and filling substance sealed therein, wherein a first film (8) formed with a start assisting metal is formed on at least one of the electrodes (5a) and a second film (9) formed with the start assisting metal is formed on the inner surface of the glass tube (2) in proximity to the first film (8), whereby a weak discharge occurs between the second film (9) and the electrode (5a) or between the second film (9) and the first film (8).
