LED illumination device

An LED illumination device, comprising:

• a base;
• at least one flexible circuit board, for covering the base;
• a plurality of LEDs, mounted on the flexible circuit board;
• and
• a lamp cover and a lamp holder, the lamp cover having an accommodating space and an opening portion, the lamp holder being connected to the opening portion, and the lamp holder being electrically connected to a power source;
• wherein the base is mounted on the lamp holder, and is disposed in the accommodating space of the lamp cover, the base has a 360 degree curved surface, and is formed as a hollow spheral shape;
• an axis is defined by traversing the center of the lamp holder and the lamp cover;
• the at least one flexible circuit board comprises a plurality of flexible circuit boards surrounding the axis averagely;
• each flexible circuit board is an eye-shaped plate having a wide middle portion and two sharp end portions;
• the flexible circuit board is bent to conform to the base;
• two sharp end portions comprise a first end portion and a second end portion;
• the first end portion is close to the lamp holder;
• the second end portion is far away from the lamp holder, and corresponds to the first end portion;
• the wide middle portion is disposed between the first end portion and the second end portion;
• the flexible circuit board is bent from the first end portion to the wide middle portion along a first direction far away from the axis, and from the wide middle portion to the second end portion along a second direction close to the axis.
