| 摘要 |
The invention relates to the lighting field and concerns an improved lens (1 ) for LED (L), comprising: 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 said larger base (3); side walls (7), integral with said optical body (2) and said top closing wall (13), arranged for delimiting a space volume (V) comprised between the side surface. (2') of said optical body (2), the inside surface (7') of said walls (7), the top closing wall (13) and the face of said electronic board (6) associated to said support base (11 ), wherein said lens (1 ) comprises a solid shaped block (8), arranged for filling said space volume (V) and for coupling with said side walls (7), cooperating therewith by interference. |
