Abstract
A lighting system and methods for producing multi-color light effects are described. The multi-color light effects can feature at least two colors of light projected inside a firebox of an electric fireplace. The lighting system includes a projection surface, a reflective spindle, a first light-emitting device, and at least a second light-emitting device. The first light-emitting device projects light of a first color onto the reflective spindle. Light from the first light-emitting device striking the reflective spindle is reflected onto the projection surface, which can be a projection screen installed in the firebox of the electric fireplace. The second light-emitting device projects light of a second color directly onto the projection surface. The first color light and second color light can be projected onto adjacent, overlapping light projection areas of the projection screen so as to produce a realistic multi-color simulated flame effect.
