Abstract
A lighting apparatus includes a plurality of light-emitting diodes emitting red, blue, and green light. The plurality of light-emitting diodes emit light beams and are arranged so as to emit the light beams toward a focusing point. A control circuit is provided for controlling the intensity of light emission of each of the light-emitting diodes emitting red, blue, and green light. A concave reflector is provided for reflecting and radiating the light focused from the light-emitting diodes to the focusing point so that the light is further focused or scattered. The apparatus also has a position-changing mechanism for changing a relative position of the concave reflector relative to the focusing point of the light-emitting diodes.
