Abstract
Provided is a lighting device capable of implementing optical images having desired shapes through a pattern design, the lighting device including: a light source portion having at least one light source; a light guide portion having a larger thickness than a height of a light emitting surface of the light source and irradiated by an incident beam from a side; and a three-dimensional effect forming portion provided inside the light guide portion, on a first surface, or on a second surface opposite to the first surface, wherein the three-dimensional effect forming portion includes multiple patterns sequentially arranged and having respective inclined surfaces with inclined angles with respect to the first surface, wherein the multiple patterns guide light passing along the light guide portion into a first surface direction or a second surface direction by refraction and reflection from the inclined surfaces, thereby implementing line shaped beams of a first path.
