Abstract
A LED (light emitting diode) illumination device includes a ceramic substrate to integrate a plurality of LED dies and a control circuit together so that a volume of the LED illumination device can be reduced and the heat dissipation of the LED illumination device can be enhanced. The LED illumination device utilizes sound control to change the light emitted from each LED die, so that the illuminating light mixed from the emitting light of the LED dies of the LED illumination device can vary in color and brightness according to the tempo and volume of music, for example, to provide more cheerful and joyful feeling.
