Patent ID: 8277075

Claim:
An illumination device comprising: a reflection disk having a curved reflection surface which reflects light beams to a focus of the curved reflection surface; a positioning frame being located at the focus of the curved reflection surface by a first truss; a solar cell module having a solar cell which is located on a front surface of the positioning frame; at least one illumination member located on a back of the positioning frame and powered by the solar cell module; a first driving device driving the positioning frame to rotate relative to the reflection disk, when the solar cell faces the curved reflection surface, the solar cell absorbs reflected sun light so as to generate electric power, when the at least one illumination member faces the curved reflection surface, light emitted from the at least one illumination member is reflected by the curved reflection surface; a second truss and the reflection disk pivotably connected to the second truss, and a second driving device driving the reflection disk to rotate relative to the second truss.
