Multi-color simulated flame system for electric fireplaces

摘要

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.

1. A lighting system comprising:
a projection surface comprising a first light projection area and at least a second light projection area, wherein the first light projection area is adjacent to and overlaps the at least second light projection area; a first light-emitting device for projecting reflected light of a first color onto the first light projection area of the projection surface; and at least a second light-emitting device for projecting light of a second color directly onto the at least second light projection area of the projection surface; wherein the first light-emitting device and second light-emitting are installable behind the projection surface; wherein at least the first light-emitting device creates a multi-chromatic flame effect comprising a concentration of light proximate to a simulated fuel source with visible wavelengths ranging between about yellow and about red and the second light-emitting device creates a multi-chromatic flame effect comprising a concentration of light proximate to a simulated fuel source with visible wavelengths ranging between about violet and about blue; wherein the light of the first color overlaps the light of the second color to produce the multi-chromatic flame effect appearing with a gradient of colors, shades, and hues to imitate a real flame.
