Abstract
The illumination system includes a light source, a diffusing element and a specular back reflector. The light source is configured to emit light towards the specular back reflector reflecting at least part of the light emitted by the light source so as to illuminate the diffusing element. The specular back reflector is shaped to generate a substantially homogeneous distribution across the diffusing element of a light flux impinging on the diffusing element.
