Abstract
A lighting lens having a multiplicity of lenticules is disclosed, and in particular the use of aspherical lenticules is disclosed. The lenticules are of two or more standard types, each type being defined be a different cross sectional curvature. The different lenticle types are distributed across one side of the lens in an intermixed pattern. By selecting two standard lenticule types, and determining a weighted ratio, a lens for a desired lighting pattern may be made without having to specifically design the individual lenticules, or the particular lenticle arrangement.
