Abstract: An illustrator with light emitting diodes provided in the invention includes a rear housing having a cavity. A front housing is disposed in the cavity, wherein the front housing includes through holes. An illuminating module is sandwiched between the rear housing and the front housing, wherein the illuminating module includes a substrate and light emitting diodes. Two opposite surfaces of the substrate are in contact with the rear housing and the front housing respectively and directly. The light emitting diodes are arranged on a surface of the substrate in an array arrangement and extending outward the through holes in a one-to-one relationship.
