摘要:
The invention provides a self-ballasted fluorescent lamp provided with a function for operating normally when the self-ballasted fluorescent lamp is inadvertently connected to a lighting fixture provided with a light bulb dimmer if the dimmer is at the maximum level, and with a function for reliably stopping operation of the ballast circuit if the dimmer is in a dimmed state and thereby latch the lamp in an unlit state and protect the ballast circuit. Even if the self-ballasted fluorescent lamp is connected to a power source via a light bulb dimmer, when a current detected by a current detection circuit exceeds a predetermined current value, a stop circuit stops operation of an inverter circuit and latches it in that stopped state in order to maintain the self-ballasted fluorescent lamp in an unlit state.
