Method for manufacturing an optical element out of glass

A method for manufacturing a vehicle headlight, the method comprising:

• providing a light source;
• manufacturing an optical element out of glass, the method for manufacturing the optical element comprising:
• providing a blank made of glass;
• placing the blank on a contact face of a supporting body;
• thereafter introducing the blank on the contact face into a cavity of a protective cap, wherein the protective cap is releasably arranged in a furnace cavity of a furnace, wherein the furnace cavity comprises at least one first heating coil which surrounds the protective cap in the furnace cavity at least in part, such that the inside of the protective cap is heated by means of the first heating coil;
• thereafter heating the blank in the cavity of the protective cap such that the blank has inside a lower temperature than at the surface;
• thereafter removing the supporting body, together with the blank resting on the contact face, from the furnace;
• subsequently press molding the blank to form the optical element comprising a light entry surface and a light exit surface;
• and
• cooling the optical element by supplying heat;
• and
• arranging the optical element together with the light source such that light from the light source can be emitted into the light entry surface of the optical element.

A method for manufacturing a vehicle headlight, the method comprising:

• providing a light source;
• providing primary optics;
• manufacturing an optical element out of glass, the method for manufacturing the optical element comprising:
• providing a blank made of glass;
• placing the blank on a contact face of a supporting body;
• subsequently introducing the blank on the contact face into a cavity of a protective cap, wherein the protective cap is releasably arranged in a furnace cavity;
• thereafter heating the blank in the cavity of the protective cap such that the blank has a lower temperature on the inside than at the edge;
• thereafter removing the supporting body, together with the blank resting on the contact face, from the furnace;
• subsequently press molding the blank to form the optical element comprising a light entry surface and a convex light exit surface;
• and
• cooling the optical element and while supplying heat;
• installing the optical element as a lens in a multilens objective;
• installing the multilens objective together with the light source and the primary optics for generating an illumination pattern by orienting light of the light source, wherein the multilens objective is oriented such that it projects the illumination pattern.
