<P>PROBLEM TO BE SOLVED: To provide a lighting unit capable of providing a lighting area having a certain flat illuminance distribution with high illuminance while saving power, and of extending an radiation distance; and to provide a lighting system equipped with it. <P>SOLUTION: This lighting unit 100 using light emitting diodes 17 as emission light sources is provided with: a light emission part 21 composed by arranging the plurality of light emitting diodes 17 on a base 19; first reflection parts 25 mounted respectively corresponding to the plurality of light emitting diodes 17 on the light emission side of the light emission part 21 for reflecting the light rays from the light emitting diodes 17 toward the light emission side by making them nearly parallel with one another; and a second reflection part 27 mounted on the light emission side relative to the first reflection parts 25 for reflecting the light rays from the light emitting diodes 17 without entering the first reflection parts 25 toward the light emission side by making them nearly parallel with one another. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
