<p>A phototherapy device for emitting a selectable spectrum of light towards a person comprising first, respectively second light paths (10, 20) for transmitting first, respectively second light beams (11, 21), first, respectively second filtering means (12, 22) for selecting first, respectively second spectra from the first, respectively second light beams (11, 21), and mixing means (2) for mixing the first and second light beams (11, 21) to a third light beam (31) which is directed towards the person, the mixing means (2) being provided to generate the third light beam (31) by passing a first percentage of the first light beam (11) and reflecting a second percentage of the second light beam (21) in the same direction. <IMAGE></p> |
