Abstract
An electrically illuminated attention-attracting device and a method of using it, relate to using a device emitting alternatingly at least two different colored lights. The device is turned on and off alternatingly to emit alternatingly the different colored lights. The device is moved to produce a visually perceptible light pattern comprising a sequence of alternating multicolored light images where the length of each one of the colored light images varies with the speed of movement of the device.
Claims11
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;
- and
- varying 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.
A method according to clam 3, further including varying the frequency F to vary the length L.
An attetion-attracting device comprising:
- light producing means for emitting at least two different colored lights;
- said light producing means including a common light source for producing said at least two different colored lights therefrom;
- circuit means coupled electrically to said light producing means for causing said common light source to emit alternatingly said at least two different colored lights at a given high rate of frequency F;
- wherein said at least two different colored lights are substantially indistinguishable from one another when said common light source is motionless;
- means for facilitating movement of said light producing means to produce a sequence of alternating segments of multicolored light images as said common light source moves, each segment having a length L;
- and
- means for varying the frequency F for to cause the length L of each one of the segments of the colored light images to vary with the velocity V of movement of the device in accordance with the formula L=V/F.
