US Patent 7976188 LED illumination device and illumination module using the same

A LED illumination device includes a base plate, a plurality of LEDs, a driving circuit and a control circuit. The plurality of LEDs, the driving circuit and the control circuit are arranged on a surface of the base plate and electrically connected to each other. The control circuit is configured for controlling the driving circuit to output a driving power. The plurality of LEDs emit light based upon the driving power. Thus the base plate, the LEDs, the driving circuit and the control circuit are integrated in a same device for simplifying the whole structure thereof to be easily assembled.
