Abstract:
Provided are an optical member capable of implementing optical images having desired shapes through a pattern design, and a lighting device using the same, the optical member including: a three-dimensional effect forming portion provided on a first surface of a base substrate; and a multiple effect forming portion disposed in a lamination form with the three-dimensional effect forming portion, wherein the three-dimensional effect forming portion has multiple main patterns sequentially arranged in a first direction on the first surface and having respective inclined surfaces with an inclination angle with respect to the first surface, wherein the multiple main patterns implement a line shaped beam of a first path by guiding a first incident beam into a first surface direction through refraction or reflection from the inclined surfaces, wherein the multiple effect forming portion are sequentially arranged in a second direction crossing the first direction and has multiple optical patterns.
