<P>PROBLEM TO BE SOLVED: To provide a lighting device capable of reducing irregular illuminance of illuminating light. <P>SOLUTION: In the lighting device 100: emitted light L is made to be incident on an incident surface 22 of a condenser lens 20; the position of an optical axis of the emitted light L on the incident surface 22 is such a position that a distance from a center of the incident surface 22 becomes longer as a distance between the center 12c of an emitting surface forming area 12 and an emitting surface 14 becomes longer; on the emitting surface positioned in a predetermined direction from the center 12c of the emitting surface forming area 12, the position of the optical axis of the emitted light L on the incident surface 22 is located in the predetermined direction from the center of the incident surface 22; and a plurality of condenser lenses 20 superimpose the emitted light L on a first fly-eye lens 50. <P>COPYRIGHT: (C)2011,JPO&INPIT |
