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.

Claims

1. A L.E.D. light assembly comprising:

a refractive lens having a front surface, a rear surface, a top edge, a bottom edge, a left edge and a right edge;

at least one horizontal row of pillow lens modules formed on the rear surface of said refractive lens;

said horizontal row having at least two pillow lens modules, said pillow lens modules each having a top edge, a bottom edge, a left edge, a right edge, and a horizontal center line x-axis;

the respective right and left edges of adjacent pillow block lens module coincide to form vertical intersection lines,

a plurality of L.E.D.'"'"'s each having a longitudinally extending z-axis;

an individual L.E.D. is mounted a predetermined distance D1 behind each of said pillow lens modules;

the z-axes of said L.E.D.'"'"'s being substantially aligned with the horizontal center line x-axes of said pillow lens modules;

a plurality of vertically oriented convex flute strips and each has a longitudinally extending y-axes;

said vertically oriented convex flute strips being formed on the front surface of said refractive lens in front of the respective vertical intersection lines between adjacent pillow lens modules and in substantial parallel alignment with said vertical intersection lines; and

vertical planar strips are formed on the front surface of said refractive lens intermediate each of said vertically oriented convex flute strips.

2. A L.E.D. light assembly as recited in claim 1 wherein said vertical convex flute strips have a width W1 and said vertical planar strips have a width W2 and W2 is greater than W1.
