A lenticular lens containing a multiplicity of multi-sided lenticules useful with reflector lamps provides improved light distribution by having the lenticules oriented to avoid parallelism with a projected light image and distributed in a plurality of zones or bands concentric about said optical center. The size and light-spreading ability of the lenticules in each zone is selected to provide the desired light distribution. Parallelism is avoided by having the lenticules arrayed in a plurality of wedge-shaped sections circumferentially arranged in a circle around the optical center of the lens and extending through the zones with the lenticules in each section arrayed in a uniform, close-packed hexagonal array of parallel rows with the longitudinal axis of one of the rows being radially aligned with respect to the optical center of the lens, so that none of the sides of the lenticules are parallel to the light source image projected off the reflector.
A lenticular lens comprising an optical center, an optical edge, a light-receiving side and a light-transmitting side and containing a plurality of lenticules having multiple sides on said light-receiving side wherein said lenticules are arranged in a plural number of wedge-shaped sections circumferentially arranged around said optical center of said lens, the number of sections being at least twice the number of sides of the lenticules and wherein said lenticules are arranged in each said section in a uniform, close-packed hexagonal array of parallel rows with the longitudinal axis of one of said rows in each said section aligned with a radius extending from said optical center, said lenticules further having a curved light-receiving surface.
