Abstract
An optical light diffuser component and a method of producing the same. The component includes at least one substrate material with an index of refraction of nand at least one optical coating on the substrate having an index of refraction of n. The indices nand nare different. The optical light diffuser component produces uniform and diffuse light pattern from spot like light source, such as LED lamp, in terms of high optical transmission. The optical transmission is better than 90% at the visible spectrum of the light.
