Claim:
1. An integral irradiation unit for hardening light-hardening polymer compositions, comprising: at least one UV light source whose percentage of total radiation in a wavelength range of >700 nm is less than 15%, and in a wavelength range <300 nm is less than 15%, wherein the at least one UV light source is configured to provide a wavelength spectrum in which the actuation of the light-hardening polymer compositions and a reaction rate of a hardening process is at maximum, at least one mold cavity for receiving light-hardening polymer compositions, at least one transparent element that is transparent to UV light generated by the UV light source and is in contact with the light-hardening polymer compositions, wherein the at least one transparent element is made of a polymer material selected from the group of acrylic polymers, said integral irradiation unit characterized in that it comprises an interconnected unit of said at least one mold cavity and said at least one UV light source.
