Abstract

Abstract A L.E.D. light assembly having a refractive lens having a front surface and a rear surface. A plurality of horizontal rows of pillow lens modules are formed on the rear surface of the refractive lens. The respective edges of the pillow lens modules coincide with adjacent pillow block lens modules to form both vertical and horizontal intersection lines. A plurality of vertically oriented convex or concave flute strips are formed on the front surface of the refractive lens in the front surface of these respective vertical intersection lines. A plurality of L.E.D.'s are mounted on a printed circuit board spaced a predetermined distance behind the rear surface of the refractive lens. There is one L.E.D. for every pillow lens module. Vertical oriented planar strips are formed on the front surface of the refractive lens intermediate each of the vertically oriented convex or concave flute strips. The combined effect of the different structures forming the refractive lens is to produce light emitted from the front surface of the refractive lens that has a solid look with no dark spots being projected forwardly from the L.E.D. assembly.
