Abstract
LED-integrated lens comprising a light-entering section (1) in the shape of a hole, a light-emitting section (2) in the shape of a cup, incorporating an optical lens (3) positioned between said light-entering and light-emitting sections (1, 2) wherein the external surfaces of the light-entering (1) and of the light-emitting (2) sections include portions having densely-distributed convex facets. This lens enhances light utilisation efficiency, avoids creating spots with colour aberration hence greatly improves colour rendering.
