Electric lighting devices having multiple light sources to simulate a flame

An electric lighting device that simulates a flickering flame, comprising:

• a housing having an interior cavity;
• a projection screen coupled to the housing such that at least a portion of the projection screen extends from the housing, wherein the projection screen comprises a curved shape and a center line that bisects the projection screen vertically;
• a set of light sources disposed within the interior cavity at an angle with respect to the projection screen and first and second lenses according to the Scheimpflug principle to account for the curved shape of the projection screen, wherein the light sources are disposed with respect to the projection screen such that light from each of the light sources is emitted on to the projection screen;
• a light controller configured to vary one or more parameters of at least one of the first, second, and third light sources;
• and
• wherein the light sources collectively comprise an array of micro-LEDs mounted to a circuit board, and wherein the circuit board is tilted at a first angle with respect to a face of the first lens that is closest to the circuit board, such that the circuit board and the face are not parallel to one another, and wherein the micro-LEDs are configured to project an image comprising a plurality of overlapping focal zones that are defocused at the projection screen.
