Electric lighting devices that simulate a flickering flame
Abstract:
Various embodiments of electric lighting devices, and especially electric candles, are described. The devices include a projection screen onto which light can be emitted. Advantageously, the projection screen can move with respect to the device's housing to thereby create a flickering flame effect. The device can include one or more magnets disposed outside of the housing that can interact with an electromagnetic field generated by the device to thereby move the projection screen.
