Patent ID: 6902563

Claim:
An irradiation device for the treatment of totally or partially cell mediated inflammations of the skin and the viscera, comprising at least one UV emitting radiation source for the irradiation of larger areas to be treated, the emitted wavelength on the treatment area being at least 400 nm and comprising a wavelength range of 400-500 nm, wherein less than 7% of the overall optical output are emitted in the UV range, and wherein at least 30% of the optical output are emitted in the range of 400-500 nm; and a phosphor material with UVC-transparent carrier material arranged in front of the radiation source, wherein said UVC-transparent carrier material is a fluorescent foil made of silicone elastomer or fluoropolymer doped with anorganic phosphor particles, wherein the irradiation device comprises means for the generation of optical pulses on the area to be treated, the generated optical pulses having a peak irradiation intensity and an energy density, the peak irradiation intensity of the generated optical pulses being higher than 0.5 W/cm 2 and lower than 100 kW/cm 2 , the energy density of one emitted optical pulse being between 0.05 and 10 J/cm 2 .
