摘要： A circuit includes a number of LEDs connected in series, and first and second electronic switches. An anode of a first one of the LEDs is connected to a first power supply. A control terminal of the first electronic switch receives a control signal. A first terminal of the first electronic switch is connected to a second power supply. A second terminal of the first electronic switch is grounded through a first resistor. A control terminal of the second electronic switch is connected to the second terminal of the first electronic switch. A first terminal of the second electronic switch is connected to a cathode of a last one of the LEDs. A second terminal of the second electronic switch is grounded through a second resistor.
