An illumination device includes a reflection disk, a positioning frame, a solar cell module, an illumination member and a driving device. The positioning frame is located at the focus of the curved reflection surface of the reflection disk. The solar cell module and the illumination member are respectively connected to the front and back of the positioning frame. The driving device is used to drive the positioning frame to rotate relative to the reflection disk. When the solar cell faces the curved reflection surface, the solar cell absorbs the reflected sun light to generate electric power. When the illumination member faces the curved reflection surface, light emitted from the illumination member is reflected by the curved reflection surface. |
