DEVICE AND METHOD FOR TREATING A SUBSTANCE WITH UV RADIATION

摘要

In order to efficiently treat by UV radiation and ensure a long lifetime for radiation sources, the invention proposes a device for treating a substance with UV radiation, in particular containing a hardening additive which comprises a plurality of UV radiation sources and consists of at least two different LEDs emitting two different types of UV radiation. Said invention also relates to a method for treating a substance with UV radiation, in particular for hardening an adhesive consisting in placing an UV-radiation-reacting substance in the radiation area of said plurality of UV radiation source which comprises at least two different LEDs emitting different types of UV radiation and in exciting said plurality of UV radiation sources in such a way that it generates the UV radiation having a predefined UV light composition and/or concentration.
