The direct light exiting the first emitting surface has a luminance profile which has a narrow peak in the angular distribution around the direct-light direction and is uniform across the first emitting surface. Each light-emitting device includes a light emitter having an emitting surface and at least a pair of collimation lenses illuminated by the light emitter.
