Headlight lens

A method for producing a vehicle headlamp lens having at least one light entry surface and at least one optically effective light exit surface wherein glass, (for example, in gob and/or liquid form) is blank-pressed between a first mold and at least one second mold to form a one-piece member compris...

Beschreibung
Zusammenfassung:	A method for producing a vehicle headlamp lens having at least one light entry surface and at least one optically effective light exit surface wherein glass, (for example, in gob and/or liquid form) is blank-pressed between a first mold and at least one second mold to form a one-piece member comprising a first partial light conducting part and a light tunnel, which transitions into the first partial light conducting part by means of a bend. The glass is, for example, drawn into the second mold by means of an under pressure and the first partial light conducting part is at least partially over molded with transparent plastic to form a second partial light conducting part so that the first partial light conducting part and the second partial light conducting part form and/or shape a light conducting part for imaging the bend as a light-shadow line.
