REFLECTIVE DIFFUSION LENS AND LIGHTING INSTALLATION

摘要

The present invention relates to a reflective diffusion lens comprising: a bottom surface concave toward a reflective surface, and having a vertical section formed into a parabola or a normal distribution to guide incident light to the reflective surface; and the reflective surface concave toward the bottom surface, and having a vertical section formed into a parabola or a normal distribution to totally reflect the incident light guided to the bottom surface. In addition, the present invention relates to a lighting device comprises: at least one light source emitting a light; the reflective diffusion lens condensing the light from the light source; and a reflective plate positioned on the lower side of the light source, and controlling the direction or the amount of the rays of the light reaching the reflective plate.
