Abstract
An illumination device includes a base, a flexible circuit board disposed on the base, and a plurality of illumination units. The flexible circuit board has a plurality of first branches and at least one second branch which are connected together. Each of the first branches has a radius of curvature, and the radii of curvature of the first branches are different from or identical to one another, so that the first branches are assembled to form a curved surface. The second branch extends from one of the first branches. After the first branches are assembled, the second branch is overlapped with another first branch. The illumination units are packaged onto the first branches of the flexible circuit board. Here, the illumination units located on one of the first branches is electrically connected to the illumination units located on another of the first branches through the second branch.
