Abstract
An illuminant comprising a transparent substrate layer with a first index of refraction, a connecting layer with a second index of refraction that differs from the first index of refraction, and a metallic, translucent layer, wherein the connecting layer is arranged between the substrate layer and the metallic layer, and wherein on the side facing the connecting layer the substrate layer comprises a plurality of decoupling structures suitable for decoupling light that propagates within the substrate layer from the substrate layer in the direction towards the metallic layer.
Claims23
An illuminant comprising:
- a transparent substrate layer with a first index of refraction;
- a connecting layer with a second index of refraction that differs from the first index of refraction;
- and
- a metallic, translucent layer;
- wherein the connecting layer is arranged between the substrate layer and the metallic layer, and wherein the substrate layer comprises a plurality of decoupling structures on the side facing the connecting layer, said decoupling structures being suitable for decoupling light that propagates within the substrate layer from the substrate layer in the direction towards the metallic layer.
A method for producing an illuminant comprising:
- providing a transparent substrate layer with a first index of refraction, wherein on a first side the substrate layer comprises a plurality of decoupling structures suitable for decoupling light that propagates within the substrate layer from the substrate layer;
- coating the first side of the substrate layer with a connecting layer having a second index of refraction that differs from the first index of refraction;
- coating the connecting layer with a metallic, translucent layer by way of physical vapor deposition.
