ABSTRACT:
The light shield-reflector for a lighting implement comprising a substantially tubular base associated with a reflector element of multiple type constituted by a set of superimposed wings spaced apart from each other. The structure of the wings shows substantially a "U"-shaped plan and a parabolic cross-section. The light flux forms a cone-shaped light and diffuses by passing through the space existing between two adjacent wings.
