Abstract
A lighting system includes a power supply unit, a power conversion unit, a lighting unit, a first switching unit, and a first reset unit. The power supply unit is used to supply a first and a second power signal. The power conversion unit receives and converts the first power signal. According to the first power signal, a first lighting module of the lighting unit emits light. The first switching unit is connected to a first node between the first lighting module and a second lighting module for receiving the second power signal, so that the second lighting module emits light according to the second power signal. The first reset unit receives the second power signal; wherein when the second lighting module changes from lighting to no lighting, the first reset unit causes the power conversion unit to stop operating and then restart.

A lighting system, comprising:
- a power supply unit, used to supply a first power signal and a second power signal;
- a power conversion unit, electrically connected to the power supply unit, for receiving and converting the first power signal;
- a lighting unit, including a first lighting module and a second lighting module connected to each other in series, wherein the first lighting module is electrically connected to the power conversion unit and emits light or not according to the first power signal;
- a first switching unit, electrically connected to the power supply unit for receiving the second power signal, and electrically connected to a first node between the first lighting module and the second lighting module to cause the second lighting module to emit light or not according to the second power signal;
- and
- a first reset unit, electrically connected to the power supply unit and the power conversion unit for receiving the second power signal;
- wherein when the second lighting module is changed from lighting to no lighting, the first reset unit causes the power conversion unit to stop operating and then restart.
