Patent attributes
A multi-color lighting device 30 capable of emitting light of at least two colors. A group 9 of LED lamps comprising a variety of colors each color having a plurality of LED lamps disposed in an equiangular array. The color of the emitted light selected by a circuit having a schematic 16 and a switch 6, which selectively energizes lamps of the desired color. Each color of emitted light is refracted by a light converging lens 1 which surrounds group 9 of LED lamps and concentrates the light emitted by the energized lamps to intensify the light emitted by the lighting device toward an elongated output beam having a specification vertical beam width smaller than a specification azimuth. Switch 6 selectively energizes each plurality of lamps representing each color within the group to an established and usually substantially fixed power level. The established power level for each color is established as adequate when light emitted from the lighting device of that color meets a required photometric specification.
