Electronic luminary device with simulated flame
A flameless candle may include a side wall including an upper region and a lower region, a base engaged with the lower region of the side wall, and an upper surface extending from the upper region of the side wall to form an upper recess. The candle may also include a projection screen extending upwardly through an aperture in the upper surface. The position of the projection screen is fixed with respect to a position of the upper surface. Two sources of light positioned below the upper surface may project light through the aperture onto the projection screen. Circuitry may electrically connect to the first source of light and the second source of light. The circuitry may independently control each of the sources of light.
