Abstract
A method for producing an optical component of a lighting device for vehicles, wherein a base body is made of a translucent or transparent material, a screen coating is applied to an outer surface of the base body by vapor deposition or by sputtering of a coating material, wherein the screen coating is applied as a reflective coating, wherein, during the application process, first a first reflective laminate layer with a low degree of reflection and then a second reflective laminate layer with a high degree of reflection are applied.
Claims7
A method for producing an optical component of a lighting device for vehicles, the method comprising:
- providing a base body of a translucent or transparent material;
- and
- applying a screen coating to an outer surface of the base body by vapor deposition or by sputtering of a coating material, such that a first portion of the outer surface has the screen coating and a second portion of the outer surface is devoid of the screen coating,
- wherein the screen coating is applied as a reflective coating, such that light emitted by a light source of the lighting device, in a direction towards the outer surface of the base body, is reflected by the first portion of the outer surface having the reflective coating and enters the base body exclusively via the second portion of the outer surface that is devoid of the screen coating, the second portion of the outer surface thus forming a light entry surface,
- wherein, during the application process, first a first reflective laminate layer with a low degree of reflection and then a second reflective laminate layer with a high degree of reflection are applied, such that the first reflective laminate layer is disposed between the outer surface of the base body and the second reflective laminate layer.
