Abstract
A flameless candle includes: a candle body; a projection screen; a supporting portion; a moving portion; an LED; and a magnetic-field-inducing circuit. The projection screen extends upwardly from an upper surface of the candle body, has a flame shape, and has a fixed position with respect to the upper surface of the candle body. The moving portion is supported by the supporting portion and includes: a transparent lens oriented diagonally; an arm extending downwardly; and a magnet on the arm. The LED is oriented to project light upwardly and diagonally such that the projected light travels through the lens, through an aperture of the upper surface of the candle body, and onto an outer surface of the projection screen. The magnetic-field-inducing circuit includes a coil that successively attracts and repels the magnet.
