A monolithic lighting device is disclosed. According to an embodiment of the present invention, the monolithic lighting device includes a monolithic lens, refracting a two-dimensional beam of light transferred from an outside and condensing the refracted beam into a one-dimensional beam. The monolithic lens has a first refraction surface, refracting the two-dimensional beam of light transferred from the outside to be diffused inside the monolithic lens, and a second refraction surface, converting the two-dimensional beam diffused in the first refraction surface into a one-dimensional beam by refracting the two-dimensional beam into a parallel beam to the outside if viewed from a side and condensing the refracted beam on a focal point at a distance outside if viewed from another side.
