An illuminator comprising:
- a bottom member;
- a guide unit of a polygonal ring configuration located on the bottom member;
- a plurality of first circuit boards mounted on an inner side of the guide unit, each of the first circuit boards having a first light emitting diode mounted thereon;
- a plurality of second circuit boards mounted on an outer side of the guide unit, each of the second circuit boards having a second light emitting diode mounted thereon;
- a light guide member positioned inside the guide unit, the light guide member being optically aligned with the first light emitting diodes;
- and
- a top member coupled to the bottom member to surround the first and second light emitting diodes and the light guide member, the top member including a window through which an inner area of the light guide member is exposed, a transparent area coupled to the bottom member and an opaque area connecting the window and the transparent area,
- wherein the guide unit is positioned between the transparent area and the light guide member,
- wherein the first light emitting diodes are opposite the light guide member and the second light emitting diodes are opposite the transparent area, and
- wherein light emitted from the first light emitting diodes is directed outside the window through the light guide member, and light emitted from the second light emitting diodes is directed to the transparent area.
