Zusammenfassung:	The adjustable LED lens has a body having a light incident surface and a light-emitting surface respectively mounted on two opposite sides of the body. The light-emitting surface has a concave tapered surface. The adjustable LED lens is mounted on a holder. A distance between the adjustable LED lens and the holder is changeable. An LED is mounted on the holder, wherein a light generated by the LED passes through the light incident surface and the light-emitting surface of the body. The concave tapered surface of the light-emitting surface increases a light distribution angle to increase an illumination range and decrease a glare. The distance between the adjustable LED lens and the LED is changeable to adjust a light shape as desired.
