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.

Abstract: A telecommunication apparatus includes a shelf and a plurality of packages. Optical fibers are laid around a rear surface of the shelf in a direction of Z2. Each of the optical fibers is dragged in a direction of X1 into a corresponding cartridge from a rear surface thereof. The cartridge is provided near an upper side of the rear surface as an excessive length treating portion. Then the optical fiber is drawn out of an upper surface of the cartridge so as to enter a space formed in the upper shelf from the rear surface thereof. After that, the optical fiber is extended and connected to an optical plug provided on a front portion of the package.
