<P>PROBLEM TO BE SOLVED: To provide a lighting system and an image capturing apparatus wherein a quantity of light can be uniformly maintained over the whole surface of a substrate having a plurality of two-dimensionally disposed LEDs, and the life times of the plurality of LEDs can be uniformed regardless of their disposed positions in the substrate. <P>SOLUTION: This lighting system has a plurality of light emitting devices two-dimensionally disposed on the substrate, and the plurality of light emitting devices are disposed so that the density of the light emitting devices disposed in the center part of the substrate becomes relatively smaller compared with the density of the light emitting devices disposed in the peripheral part of the substrate. <P>COPYRIGHT: (C)2010,JPO&INPIT |
