Provided are an optical member (100) capable of implementing optical images having desired shapes through a pattern design, and a lighting device using the same, the optical member (100) including: a three-dimensional effect forming portion (11) provided on a first surface of a base substrate (10); and a multiple effect forming portion (12) disposed in a lamination form with the three-dimensional effect forming portion, wherein the three-dimensional effect forming portion (11) has multiple main patterns (111) 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 optical patterns (121) of the multiple effect forming portion (12) are sequentially arranged in a second direction crossing the first direction and has multiple optical patterns. |
