METHOD FOR ACTIVATING A PHOTOCATALYTICALLY ACTIVE OUTER LAYER DEPOSITED ON A COMPOSITE

The invention relates to a method for activating a photocatalytically active, for example titanium-dioxide-containing, outer layer (13; 23) deposited on a composite, by means of at least one element (14; 24) 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 (14; 24)within the composite; b) forming at least one sensor (16; 26) within the composite; c) recording an actual value of a physical variable characterizing luminous radiation by means of the at least onesensor (16; 26), wherein the luminous radiation is emitted by a light-generating second element (15; 25); 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 (14; 24) if the actual value is below or above the first threshold value. 本发明涉及一种借助于至少一个产生辐射(例如用于产生紫外辐射)的元件(14；24)来活化沉积在复合物上的有光催化作用的(例如含二氧化钛的)覆盖层(13；23)的方法
