Abstract

Reflections on headlamp reflectors and the like, made of transparent plastic material and comprising an internal surface and an external surface made reflective by metallization, characterized in that, in at least one area of the reflector, the image of the external surface on the Diopter bounded by the internal surface between the plastic material and the ambient air is a parabolic surface, keeping the interval between the surfaces that constitute the thickness of the reflector at least appreciably constant.
