Japanese Patent JP6513713

B2

The present invention relates to a lighting device capable of implementing, by means of a pattern design, and a pattern and light source layout design, a line-shaped beam having a three-dimensional effect, and various optical images using same, the lighting device comprising: a light guide portion having a first surface and a second surface which is the opposite side of the first surface; a three-dimensional effect forming portion disposed on the light guide portion; and a light source portion irradiating a beam to the middle part of the light guide portion from the thickness direction of the light guide portion, wherein the three-dimensional effect forming portion has a pattern, and the pattern has a plurality of unit patterns, wherein the plurality of unit patterns are sequentially arranged, have respective inclined surfaces having inclination angles with respect to the first surface or the second surface, and guide, by means of reflection and refraction on the inclined surfaces, the incident beam in the light guide portion to a first surface direction towards which the first surface faces, or to a second surface direction towards which the second surface faces, thereby generating a line-shaped beam of a first path which is orthogonal to the respective pattern extension directions of the plurality of unit patterns.
