An LED module includes a carrier and a number of light sources. Each light source is arranged on the carrier in such a way that the LED module comprises a radiation uniformity which is less than the statistical mean of a radiation uniformity distribution, wherein the radiation uniformity distribution is based on a plurality of LED modules with a random arrangement of the light sources.

A subassembly for a document validator. In an implementation, the subassembly includes a housing, a light pipe core seated in the housing, a light control layer and at least one light source. The apparatus may also include a prism structure layer between a top diffusing surface and the light control structure. The housing may also include at least one input light port on at least one end of the light pipe core.
