Abstract
An illumination device including a base, a heat dissipation member, at least one flexible printed circuit board (FPC), and a plurality of light-emitting elements is provided. The heat dissipation member disposed on the base has a central axis, a plurality of holding curvy surfaces and a plurality of heat dissipation channels extending along the central axis, wherein the holding curvy surfaces and the heat dissipation channels are staggered and arranged about the central axis, and each of the holding curvy surfaces radially extends along the central axis. The flexible printed circuit board is disposed on the holding curvy surfaces. The light-emitting elements are disposed on the flexible printed circuit board. An assembling method of the illumination device is also provided.
