ABSTRACT:
Various embodiments described herein comprise array of light emitting diodes and a cylindrical lens having front and rear curved surfaces. The cylindrical lens is disposed to receive light from the light emitting diodes and to redistribute the light. The cylindrical lens is located no more than about 8 inches distance from the front an illumination target, which may for example, comprise products on shelves in a refrigerator. The front and rear surfaces of the cylindrical lens are shaped to provide substantially uniform illumination across the target.
