Abstract

The device has a hollow body bounded by a wall (15) provided with reflective inner surfaces for multiple reflection of light. The inner surfaces (14) of the hollow body have a degree of reflection of at least 90 per cent and are light scattering. The wall of the hollow body has at least one light outlet opening (16) penetrating the wall.
