Abstract
Various components for artificial candles and other lighting devices are described that can be used to create a realistic flame effect in the devices. The devices include a flame piece or element that extends upwardly from a body of the device. A light source can be disposed with respect to the flame piece such that the flame piece is illuminated. A variety of drive mechanisms could be disposed within the body of the device that can cause movement of the flame piece with respect to the body or housing. The flame piece can be coupled to a body or housing of the device using various components to suspend at least a portion of the flame piece within the body or housing.
