A light-emitting system includes: a driver device operable to generate a driving signal that alternates between a first state, where voltage of the driving signal is higher than a predetermined threshold voltage, and a second state, where voltage of the driving signal is lower than the predetermined threshold voltage; and a light-emitting device connected electrically to the driver device for receiving the driving signal therefrom, and operable to enter a light-emitting state when the driving signal is in one of the first and second states, and to enter a non-light-emitting state when the driving signal is in the other of the first and second states. The light-emitting device includes at least one light-emitting diode. |
