The radiation device has an array () of light-emitting diodes () providing light beams which are directed onto a focus region () at the input end of a light conductor (), used for directing a focused light beam onto the radiation point. The light-emitting diodes are supported in a planar holder () at different inclination angles, for providing a light cone illuminating the light conductor input end from their output beams.
