Abstract

A wide angle directed reflector is disclosed. The directed reflector includes a lenticular layer including at least one array of lenslets, each of which having a focal length, The directed reflector further includes a reflective layer which is disposed relative to the lenticular layer. The lenticular layer and the reflective layer are constructed, designed and relatively disposed such that light incident at an angle of incidence on the lenticular layer is reflected by the reflective layer and redirected through the lenticular layer at a substantially constant angle relative to the angle of incidence.
