摘要
An apparatus for illumination comprises a light source operable to generate a radiation pattern. The apparatus further comprises a light guide adjacent the light source, which is operable to be illuminated by the radiation pattern. The light guide comprises a pattern of varying sized dots operable to diffusely reflect the illuminating radiation pattern. The dot pattern comprises monotonically increasing dot sizes intermediate between the smallest and the largest dot sizes, such that the smallest dot size is proximate to the light source and the largest dot size is distal from the light source.
