An improved lens (1) for LED (L), includes: an optical body (2) with a substantially truncated-cone or circular paraboloid shape, with a larger base (3) facing outwards and a smaller base (4) arranged for receiving, in a special recess (5), a LED (L) associated to an electronic board (6) coupled to a support base (11); a top closing wall (13) associated to the larger base (3); side walls (7), integral with the optical body and the top closing wall, arranged for delimiting a space volume (V) included between the side surface (2′) of the optical body, the inside surface (7′) of the walls (7), the top closing wall and the face of the electronic board (6) associated to the support base, wherein the lens includes a solid shaped block (8), arranged for filling the space volume (V) and for coupling with the side walls, cooperating therewith by interference. |
