<P>PROBLEM TO BE SOLVED: To provide an illumination device lineup having many variations that respond to various illumination ranges and installation distances while the cost is suppressed, and to provide a producing method for implementing the illumination device having the many variations. <P>SOLUTION: In the illumination device, each cell 2 includes a light-emitting element mounted on a board 4 and a lens that is disposed so as to be paired with the light-emitting element. A relative positional relation between the light-emitting element and the lens in each cell 2 varies according to a position on the board 4. Therefore, light is emitted from the light-emitting element to the outside with a non-zero angle that is determined in each cell 2 with respect to a direction perpendicular to the board 4. <P>COPYRIGHT: (C)2011,JPO&INPIT |
