Abstract
An artificial LED candle includes a flame element with an upper section with a flame silhouette outlook, at least one first LED light source used for illuminating a center part of the upper section of the flame element, and at least one second LED light source used for illuminating one or two side parts of the upper section of the flame element. The center part of the upper section is illuminated by both the first and the second LED light sources, while the two side parts of the upper section is illuminated only by the second LED light source. Therefore, a center part is brighter than the two side parts of the upper section of the flame element, just like a real burning candle flame. Color simulation and light shadow presented on the flame element is more realistic, a simulate effect is improved.
