Abstract
An illumination apparatus is provided with an LED array including a plurality of LEDs and a second lens array including a plurality of lenses. The LEDs and the lenses are arranged in lengthwise and crosswise directions and aligned such that a relationship between a number of the LEDs and a number of the lenses are mutually prime with each other in both lengthwise and crosswise directions. Primary illumination light from the LED array is split into a plurality of pieces of secondary illumination light by the lenses and thereafter superposed to irradiate. All of pieces of the secondary illumination light are provided with different strength peak positions of the illumination light and therefore, light having a uniform intensity can be irradiated to an irradiated region.
