Abstract

The present invention relates to a lens for an LED lamp, capable of implementing light distribution as desired, and more particularly, to a streetlamp. A lens for an LED module, which is generally used in safety lights, tunnel lighting, etc., includes a V-cutting portion formed in a floor surface of a recessed portion formed into a flat surface portion of the lens, wherein the refractive angle and direction of light are controlled by an angle formed by a sloped surface of the V-cutting portion and a straight portion converging with the sloped surface, thus enabling a light distribution (light-emitting surface brightness and light distribution uniformity) value to be implemented as desired and the emitted light to be distributed over a rectangular region without shadows.
