<P>PROBLEM TO BE SOLVED: To provide a desk-top illumination device shining in rainbow color in which volume of light and lighting mode change corresponding to changes of sound. <P>SOLUTION: The sound sensitive rainbow color desk-top illumination device is constructed of a small number of RGB full-color LEDs, an acrylic rod containing reflective objects which has a cross-section in light emitting direction of the LEDs, a microcomputer for LED control, and a microphone connected to it. The acrylic rod is emitted in rainbow color by turning the lighting order of the RGB full-color LEDs by a soft ware built in the microcomputer, and its light volume is gradually increased in a certain time and then, gradually decreased in a certain time, and then, intensity change and frequency change of the sound from the microphone are detected to change the light volume and lighting mode in a certain range. <P>COPYRIGHT: (C)2011,JPO&INPIT |
