Abstract:
1. An artificial light source generator, comprising: at least one luminescent set, comprising: a light source, for generating light beams; a parabolic mirror, having a focus, wherein the light source is disposed at the focus, so that the light beams generated by the light source are transmitted in a parallel direction through the parabolic mirror; a supporting seat, for supporting the light source; a first lens array, having a plurality of first lens units, wherein each of the first lens units has a first focal distance; and a second lens array, having a plurality of second lens units, wherein the second lens array is parallel to the first lens array, and the distance between the second lens array and the first lens array is 0.5 to 1.5 times the first focal distance, wherein the first lens units and the second lens units are divided into a plurality of regions where lenses are gathered, and the regions where the lenses are gathered are spaced apart by a shading material, wherein each of the plurality of regions of the first lens units and the second lens units is spaced apart by the shading material in a cris-crossing configuration; and a projection plane, for placing a module being tested, wherein the projection plane is separated from the luminescent set at a suitable distance, so that the light beams passing through the first lens array and the second lens array are projected on the projection plane, and the light beams passing through each of the second lens units cover the entire projection plane.
