To provide a compact self-ballasted fluorescent lamp intended to be used for other models and to be miniaturized by standardizing.
This compact self-ballasted fluorescent lamp is formed by storing an arc tube 18 and an inverter circuit 24 to light the arc tube 18 in a cover to be mounted with a base. The compact self-ballasted fluorescent lamp is made to have incandescent lamps having power consumption of 40 W equivalent, 60 W equivalent and 100 W equivalent in common. Thereby, a lighting circuit 16 is formed as a first block base 23 and a second block base 28 by standardizing the sections using the components having the same constant to facilitate designing the circuit. The base can be disposed by miniaturizing it by standardizing them, and the components can be used for other models and can be miniaturized by mainly forming those sections which can not be standardized on a circuit board.
