LENS FOR LED LIGHT LIGHT TO REALIZE DISTRIBUTION

摘要

PURPOSE: A lens for a LED(Light Emitting Diode) lamp is provided to control the refraction angle of light by varying the tilt angle of the inclined surface of a V-cutting part. CONSTITUTION: A planar part(4) is formed in one side of a lens(1). A convex part(3) is formed in the other side of the lens. A concave groove part(2) is formed in the planar part in a cupola shape. A V-cutting part(8) is formed in the bottom side of the groove part. The V-cutting part has two inclined surfaces and one straight line part. A protrusion is formed in the edge of the convex part.
