A lighting apparatus comprising: a light guide portion including a first surface and a second surface opposite to the first surface, and having a predetermined thickness between the first surface and the second surface; a three-dimensional effect formation portion disposed in the light guide portion or on a surface thereof and including a pattern; a first light source disposed in a first area of the pattern and irradiating incident light of a first color toward the pattern; and a second light source disposed in a second area of the pattern and irradiating incident light of a second color different from the first color toward the pattern, and wherein the pattern includes inclined surfaces sequentially arranged on a pattern arrangement surface parallel with the second surface and having an inclination angle with respect to the pattern arrangement surface, and generates linear light of a first path by guiding the incident light in a first surface direction which faces the first surface or in a second surface direction which faces the second surface by refraction and reflection at the inclined surface, characterized in that the first light source is disposed at the edges of the light guide portion and the second light source is disposed at a central portionof the light guide portion, wherein the light guide portion has a circular shape on a plane, and the pattern includes a polygonal outermost pattern unit which is inscribed in the second surface of the light guide portion or in an inside circular plan corresponding to the second surface, and a plurality of pattern units in a concentrically circular shape arranged to be evenly spaced from the outermost pattern unit toward the center. a light guide portion including a first surface and a second surface opposite to the first surface, and having a predetermined thickness between the first surface and the second surface; a three-dimensional effect formation portion disposed in the light guide portion or on a surface thereof and including a pattern; a first light source disposed in a first area of the pattern and irradiating incident light of a first color toward the pattern; and a second light source disposed in a second area of the pattern and irradiating incident light of a second color different from the first color toward the pattern, and wherein the pattern includes inclined surfaces sequentially arranged on a pattern arrangement surface parallel with the second surface and having an inclination angle with respect to the pattern arrangement surface, and generates linear light of a first path by guiding the incident light in a first surface direction which faces the first surface or in a second surface direction which faces the second surface by refraction and reflection at the inclined surface, characterized in that the first light source is disposed at the edges of the light guide portion and the second light source is disposed at a central portionof the light guide portion, wherein the light guide portion has a circular shape on a plane, and the pattern includes a polygonal outermost pattern unit which is inscribed in the second surface of the light guide portion or in an inside circular plan corresponding to the second surface, and a plurality of pattern units in a concentrically circular shape arranged to be evenly spaced from the outermost pattern unit toward the center.
