The present invention relates to an illumination device, and more particularly, to an illumination device comprising: a supporting part including a plurality of second base boards which have round holes with different diameters and are laminated on the top of a first base board, wherein light-emitting devices are provided on the upper end of the stepped surface of each of the second base boards which are adjacent to the round hole of the corresponding second base board; and a lens part including a reflective portion which is configured to surround the outer surface of a lower part of a spherical lens and to form a plurality of stepped surfaces in a downward direction, wherein the stepped surfaces of the second base boards adjacent to the round holes are coupled with the steps surfaces of the reflective portion. Therefore, the present invention controls a light source by the refraction of a lens, and thus enables a user to easily control various colors and light quantities to produce directional illumination. |
