Abstract: The invention relates to the field of electric heating appliances, specifically an electric fireplace providing a 3D flame effect, which comprises a housing, and inside, decorative firelogs, embers, a first light projector, a second light reflector, a first light-emitting source, a second light-emitting source and a flame-imaging device; wherein the first light projector comprises a first actuator and a revolving drum connected with an output shaft of the first actuator, wherein the revolving drum scatters the light emitted from the first light-emitting source onto the decorative firelogs and the embers; wherein the second light reflector reflects the light emitted from the second light-emitting source onto the flame-imaging device. The projection of both lights simulates a realistic 3D effect of a burning flame.
