  • Patent number: 10578263
    Abstract: The present invention discloses an artificial candle lamp, including an artificial flame hood and a light-emitting component which emits light in the flame hood. The light-emitting component is disposed on an upper bracket; a lower bracket is disposed below the upper bracket; an elastic component is disposed between the upper bracket and the lower bracket; an inductance solenoid coil is disposed in the middle of the lower bracket; and a ferromagnet which extends into the inductance solenoid coil is disposed at a lower part of the upper bracket. In the technical solution, the elastic component is used to buffer the flicker generated by an electromagnetic force to form a random and gradually-attenuated flicker process, thereby effectively enhancing a simulation effect of flame flicker of the artificial candle lamp and improving use experience of a user.
