<P>PROBLEM TO BE SOLVED: To provide a simple warning light and a method of manufacturing the same, in which conventional defects such as dim impression due to variation in light emissions of light emitting elements when many light emitting elements are used simultaneously and difficulty of miniturization, are improved. <P>SOLUTION: A blinkable warning light comprises a plurality of light emitting parts for emission, a blink control circuit part, and a power supply part. It also comprises a circuit part that receives the signal äemission, electromagnetic waves, sound waves (including ultrasonic waves) of other device, vibration or change of magnetic field} emitted by a warning light which is a partner, and emits cyclic light substantially synchronous with it, and a light emitting part for emitting the cyclic light substantially synchronized. A reflecting part uses a curved surface close to the moving locus of a parabola to attain miniaturization and condensing of light on the front surface. <P>COPYRIGHT: (C)2007,JPO&INPIT |
