Abstract

An illumination device (1) for producing an illuminating light beam (7) to activate a photosensitive biological process comprises a light source element (2) configured to emit light at a wavelength range overlapping with the absorption wavelength band of the photosensitive biological process. According to the present invention, the light source element comprises a plurality of laser diodes(2) configured to emit primary light beams(3)at different wavelengths; and the illumination device (1) further comprises at least one diffusor surface (6a, 6b) configured and placed to diffusively redistribute the energy of the primary light beams(3) into the illuminating light beam (7) so that the energy density of the illuminating light beam leaving the illuminating device does not exceed the maximum permissible exposure of a human eye.
