Zusammenfassung:	The present disclosure provides a time-delay lighting circuit and a lighting device. The time-delay lighting circuit includes a first voltage-current conversion circuit configured to convert a first inputted current to a current satisfying working conditions of the light emitting component; an energy storage and discharge device configured to provide power to the light emitting component when the control switch is switched off to disconnect the external power source from the time-delay lighting circuit; a charging controller configured to charge the energy storage and discharge device when the control switch is switched on to connect the external power source to the time-delay lighting circuit; and a switch status detection circuit configured to detect an on/off status of the control switch, and when the control switch is detected to be switched off, control the energy storage and discharge device to provide power to the light emitting component.
