Wide-angle illumination device

A wide-angle illumination device comprising:

• a base having a central region and two lateral regions, the two lateral regions being respectively disposed on opposite positions around the central region, a first light emitting module being disposed on the central region, and two second light emitting modules being respectively disposed on the two lateral regions;
• a first light guiding module disposed on the central region and matched with the first light emitting module, so as to guide a first optical signal emitted by the first light emitting module toward a front of the base;
• and
• two second light guiding modules disposed on the two lateral regions and respectively matched with the second light emitting modules, each of the two second light guiding modules being utilized to guide a second optical signal emitted by a corresponding second light emitting module out of an end of the base, wherein at least one of the first light guiding module and the two second light guiding modules are an asymmetric light guiding structure.
