Disclosed is an illumination module array for a plant factory, the array comprising: first blue LED chips； second blue LED chips； a first combination of RGY phosphors applied on the first chip to form a first RGY phosphors-applied LED chip； a second combination of RGY phosphors applied on the second chip to form a second RGY phosphors-applied LED chip, wherein the first combination is configured by combining red, green, and yellow phosphors that light emission from the first RGY phosphors-applied LED chip has a spectrum having a relatively higher intensity in a red wavelength range； wherein the second combination is configured by combining red, green, and yellow phosphors that light emission from the second RGY phosphors-applied LED chip and has a spectrum having a relatively shaper change of an intensity thereof in a blue wavelength range.
