A delayed lighting system includes a light emitting circuit; a main power supply circuit connected to the light emitting circuit; a delayed lighting circuit; an energy storage circuit configured to store electrical energy from a mains electricity when the main power supply circuit supplies power to the light emitting circuit; and a control circuit connected to the energy storage circuit, the light emitting circuit, and the delayed lighting circuit respectively. When the main power supply circuit stops supplying power to the light emitting circuit, the control circuit is configured to control the energy storage circuit to supply power to the delayed lighting circuit and the delayed lighting circuit is configured to emit light.
