Abstract
Red LED chip(s) 11r, green LED chip(s) 11g, and blue LED chip(s) 11b may be connected in series. In addition, taking Pr to be red intensity, Pg to be green intensity, and Pb to be blue intensity for the same value of electric current, the ratio of the intensities among Pr, Pg, and Pb may be set so as to be 3:7:1, more or less. By integrally mounting such illumination apparatus(es) to portable equipment for illumination when using CCD image pickup element(s) to acquire image(s), improved color reproduction by CCD image pickup element(s) is permitted.
