<p>Disclosed are a light unit and an illumination system using the same. The light unit includes a top plate (200), a bottom plate (300), and at least one light source module (100) located between the top plate (200) and the bottom plate (300). The bottom plate (300) includes a specular-reflection region (300a) and a diffuse-reflection region (300b). The diffuse-reflection region (300b) includes a first reflective pattern that reflects incident light via Lambertian distribution and a second reflective pattern that reflects incident light via Gaussian distribution.</p> |
