摘要:
A fluorescent lamp includes a light-emitting tube having a pair of electrodes therein, a base in which the light-emitting tube is fixed, and a base contact pin terminal supported by the base with one end thereof projecting from the base. The base contact pin terminal is electrically connected to an electrode lead wire drawn from the light-emitting tube. The base is provided with a first power-conducting member including the base contact pin terminal having a lead plate, a connecting terminal having a lead plate and connected to the electrode lead wire, and a thermal protection element connected to the lead plate of the base contact pin terminal and the lead plate of the connecting terminal. The manufacturing processes of a fluorescent lamp provided with a thermal fuse are simplified and can be performed easily.
