    • A cold-cathode fluorescent discharge tube has a pair of electrodes for performing discharge between the electrodes in response to the application of a voltage therebetween. The fluorescent discharge tube of the invention includes an auxiliary electrode provided in the vicinity of one of the pair of electrodes, and a unit for applying the voltage between the pair of electrodes and between the auxiliary electrode and the one of the electrodes. With the auxiliary electrode, a discharge is firstly started between the auxiliary electrode and the one of the electrodes in response to the application of the voltage between the pair of electrodes. Thereafter, a discharge is started between the pair of electrodes. Thus, the start discharge is generated in the discharge tube in a relatively short period of time even if the discharge tube is set in the off state for a long time, particularly in the dark at a low temperature.
    • 冷阴极荧光放电管具有一对电极,用于响应于它们之间的电压而在电极之间进行放电。 本发明的荧光放电管包括设置在一对电极之一附近的辅助电极和用于在一对电极之间以及辅助电极和一个电极之间施加电压的单元。 利用辅助电极,响应于施加一对电极之间的电压,首先在辅助电极和一个电极之间开始放电。 此后,在一对电极之间开始放电。 因此,即使放电管长时间处于断开状态,特别是在低温的黑暗中,在放电管中也会在相对短的时间内产生开始放电。
