  • Publication number: 20130249412
    Abstract: According to one embodiment, a lighting circuit includes a first power supply circuit, a first detecting circuit, a first control circuit, and a first protecting circuit. The first power supply circuit is supplied with power from a first power supply and outputs a direct current flowing in a first direction. The first detecting circuit detects a first detection value of an electric current flowing between the first power supply circuit and an output terminal. The first control circuit compares a first detection value detected by the first detecting circuit with a reference value and controls the first power supply circuit. The first protecting circuit is connected to the first detecting circuit and reduces an absolute value of the first detection value if an electric current flows in a direction opposite to the first direction.
