Abstract

The device has a number of light emitting diodes (1) as a light source arranged next to each other on a surface (3) to illuminate an object opposite the surface. At least part of the surface can be curved concavely at least in one dimension by a mechanical effect of an arrangement provided to curve the surface. The surface is essentially round with at least one radial cut in the initial state.
