Abstract
A lighting system suitable for receiving two kinds of power signals includes a light emitting unit, a switch control circuit, first and second power adjustment circuits, and first and second switches. The switch control circuit is electrically connected to the light emitting unit, the first and second switches. When the light emitting unit and the switch control circuit receive a first power signal, the switch control circuit turns on the first switch and turns off the second switch, so that a first current drives the light emitting unit to emit. When the light emitting unit and the switch control circuit do not receive the first power signal and the second power adjustment circuit receives the second power signal, the switch control circuit turns off the first switch and turns on the second switch, so that a second current drives the light emitting unit to emit.
