Abstract:
A method of producing attention-attracting light images, comprising:using an electrically illuminated device including a common light source for emitting alternatingly at least two different colored lights;causing the common light source to turn on and off alternatingly at a given high rate of frequency F to emit alternatingly at least two different colored lights substantially indistinguishable from one another when the common light source is motionless;moving the light emitting device to produce a visually perceptible light patter comprising a sequence of alternating multicolored light images; andvarying the velocity V of the moving of the device to cause the length L of each one of the segments of the colored light images to vary with the velocity of movement of the device in accordance with the formula L=V/F.
