An optical element is assembled to a light emitting diode (LED) to form an illuminative light source. The optical element includes a transparent main body having a light guiding pillar and an extending part. The light guiding pillar has a top surface and a bottom surface having a recess. The extending part is extended from the circumference of the top surface and an end of the extending part has at least a light-emitting surface. Wherein the LED is disposed on the recess and emits light to the optical element. The extending part guides the light and enlarges the light-emitting angle.
