Abstract
The invention relates to a method for activating a photocatalytically active, for example titanium-dioxide-containing, outer layer () deposited on a composite, by means of at least one element () generating a radiation, for example for generating ultraviolet radiation. The following method steps are comprised here: •a) forming the at least one radiation-generating first element () within the composite; •b) forming at least one sensor () within the composite; •c) recording an actual value of a physical variable characterizing luminous radiation by means of the at least one sensor (), wherein the luminous radiation is emitted by a light-generating second element (); •d) comparing the recorded actual value with a first threshold value within an evaluation device and switching on the at least one radiation-generating first element () if the actual value is below or above the first threshold value.
