Claim 0:
1. A method for activating a photocatalytically active outer layer deposited on a composite by means of at least one radiation-generating element, wherein the composite comprises a substrate and a layer system deposited thereon, comprising:
Forming of at least one radiation-generating first element within the composite;
Forming of at least one sensor within the composite;
Recording of an actual value of a physical parameter measured by light radiation, by means of the at least one sensor, wherein the light radiation is radiated by a light-generating second element;
Comparing of the recorded actual value to a first threshold value by an analysis device and switching on the at least one radiation-generating first element when the actual value exceeds or drops below the first threshold value.
