1. A driving circuit for driving light emission of a light emitting component, comprising:

  • a control circuit disposed to receive a sense voltage associated with a direct-current (DC) source voltage, and configured to generate a control signal having a duty cycle that varies with the sense voltage in a monotonically increasing manner; and

    a boost converter circuit disposed to receive the DC source voltage and the control signal, and configured to provide a driving current for driving light emission of the light emitting component, the driving current having a magnitude positively correlated to the duty cycle of the control signal.
