Foil structure with generation of visible light by means of LED technology

A foil structure generating visible light using LED technology, the foil structure comprising:

• (a) a carrier foil having a first portion and a second portion, the carrier foil being folded over so that the second portion of the carrier foil is disposed above the first portion of the carrier foil;
• (b) an LED chip for generation of UV light disposed on the first portion of the carrier foil and comprising a light output face for emission of the UV light;
• (c) a color reaction layer for conversion of the UV light into the visible light;
• and
• (d) a spacing layer;
• wherein the spacing layer is arranged laterally offset relative to the LED chip such that a bottom surface of the spacing layer is disposed on the first portion of the carrier foil and a top surface of the spacing layer is disposed on the second portion of the carrier foil, or wherein the spacing layer is arranged between the light output face of the LED chip and the color reaction layer such that the bottom surface of the spacing layer is disposed on the light output face of the LED chip and the top surface of the spacing layer is disposed on the second portion of the carrier foil;
• wherein the color reaction layer is disposed above the LED chip or laterally offset relative to the LED chip;
• and
• wherein the color reaction layer comprises a structuring so that the UV light emitted from the light output face of the LED chip is not emitted into the surrounding of the foil structure.
