Abstract: A reflective diffusion lens may include a bottom surface concave toward a reflective surface, a longitudinal cross section of the bottom surface being formed in a parabolic shape or normal distribution shape such that light incident upon the bottom surface is incident upon the reflective surface, and the reflective surface concave toward the bottom surface. The reflective surface may include a concave surface having a longitudinal cross section formed in a parabolic shape or normal distribution shape to totally reflect the light transmitted from the bottom surface and incident upon the reflective surface. A lighting installation may include at least one light source to emit light, a reflective diffusion lens to collect light emitted from the light source, and a reflective plate positioned at a lower portion of the light source and adapted to adjust a direction or amount of light reaching the reflective plate.
