1. An illumination device, comprising:
- a light source; and
a lens, disposed over the light source with a predetermined gap therebetween, comprising a bottom surface as an incident surface, a pair of upper refracting surfaces, and a pair of lateral refracting surfaces,wherein the pair of upper refracting surfaces form an included angle substantially in a range of about 80°
to about 120°
, the incident surface is a substantially horizontal surface, each of the lateral surfaces is a substantially flat surface, and the incident surface and the lateral refracting surfaces form two obtuse angles are substantially in a range of about 100°
to about 115°
