ABSTRACT:
A light pipe includes a surface provided with a pattern that has diffractive properties, where the pattern has uniform, mutually different areas on the surface such that some of the areas are configured to distribute light from a light input end of the light pipe to form macroscopically uniform distribution of light and some other areas are configured to couple light out from the light pipe in order to produce lighting, and where the relative proportion of surface covered by areas configured to distribute light is arranged to decrease in relation to increase of distance from the light input end.
