Beschreibung
Zusammenfassung:	A light concentrator includes at least one light guide plate. The light guide plate has a main body and at least one light guide cavity. The main body has a bottom surface and an opposite light incident surface. The main body has a light emitting surface and two opposite lateral surfaces between the bottom surface and the light incident surface. The two opposite lateral surfaces are form a first acute angle. The distance between the two opposite lateral surfaces are gradually reduced far from the light emitting surface. The light guide cavity is formed by hollowing from the bottom surface. The light guide cavity has a reflecting surface and two opposite wall surfaces. The two opposite wall surfaces are form a second acute angle. The distance between the two opposite wall surfaces are gradually reduced far from the light emitting surface. The reflecting surface is located on one end of the light guide cavity which near the light emitting surface. There is a third acute angle between the reflecting surface and
