A fluorescent lamp includes a base, a control circuit mounted in the base, a fluorescent tube electrically connected with the control circuit, and a protection device electrically connected with the control circuit. Thus, when the temperature of the control circuit is raised excessively to reach a preset temperature value due to an overheat of the fluorescent tube, the protection device is operated to shut an electric power supplied to the control circuit so as to stop operation of the fluorescent tube and to prevent the control circuit from producing overheat, thereby protecting and preventing the control circuit from being worn out or broken due to an overheat.
