    Abstract: The present invention relates to a lighting apparatus using linear light having a three dimensional effect, the lighting apparatus comprising: a light guide unit which has a first side and a second side opposite to the first side, and has a predetermined thickness between the first side and the second side; a three dimensional effect formation unit which is disposed inside or on the surface of the light guide unit and has a pattern; a first light source, disposed in a first area of the pattern, for irradiating an incident light of a first color to the pattern; and a second light source, disposed in a second area of the pattern, for irradiating, to the pattern, an incident light of a second color different from the first color, wherein the pattern is sequentially arranged on a pattern arrangement surface parallel to the second side, has an inclined surface forming an inclination angle with respect to the pattern arrangement surface, and guides an incident light in a first side direction that the first side faces or in a second side direction that the second side faces by refraction or reflection on the inclined surface, to thereby generate a linear light of a first path.
