Patent ID: 7441927

Claim:
A lamp lens comprising: a light transmissive plate having a plurality of light refractive lenticules, formed on a surface of the lens, the lens having a center around which the lenticules are positioned and which may be sequentially counted from 1, such that the polar coordinates (R n , θ n ) of the n'th sequential lenticule center are defined by the relations: R n =s*φ*√n where R n is the radial distance from the lens center to the n'th lenticule center; and θ n =n*φ* 2*π where θ n is the angular rotation in radians around the lens center from a chosen position; and Where: n=the number of the n'th successive lenticule; s=a radial spacing parameter; and φ=2/(1+√5) (=0.618033989 . . . ).
