Beschreibung
Zusammenfassung:	A light collecting device includes at least one light guide plate having a body and at least one light guiding groove. The body has a bottom surface, a light entrance surface, a light exit surface and two opposite lateral surfaces between the bottom surface and the light entrance surface. A first acute angle is formed between the two lateral surfaces. Having a reflective surface and two opposite groove wall surfaces, the light guiding groove is formed and dented inward from the bottom surface. A second acute angle is formed between the two groove wall surfaces. The reflective surface is located at an end, close to the light exit surface, of the light guiding groove. An absolute value of a difference between the first acute angle and the second acute angle is less than or equal to 30 degrees.
