Adjustable LED lens and lamp with the same

摘要

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.

主权项

1. An adjustable LED lamp comprising:
a holder; an LED mounted on the holder; and a lens movably mounted on the holder and having
a body having a light incident surface and a light-emitting surface respectively formed on two opposite sides of the body and the light-emitting surface having a concave tapered surface; wherein the light incident surface comprises:
a flat surface; anda convex cambered surface formed on a periphery of the flat surface; and the body has
