Abstract
A ridged reflector (,) for use in an optical display (,) comprises a polymeric layer (,) having a ridged surface (,) and an opposite surface (,) opposite the ridged surface (,). The ridged surface (,) includes a series of ridges (,). Each of said ridges (,) has a first face (,) and a second face (,) intersecting the first face (,). The first face (,) is oriented at a first angle (,) relative to a plane parallel to the opposite surface (,). A reflective metallic layer (,) overlies at least the first faces (,) of the polymeric layer (,). The first angle (,) is adapted to reflect and biasedly focus light obliquely intercepting the first face (,) into a radiation pattern about a normal axis (,) extending orthogonally from the opposite surface (,). The first face (,) may be curved to tailor a shape of the radiation pattern.
