Definitions
- DE 699 23 847 T2 discloses a process for producing an optical molded article from a thermoplastic resin by injection molding, wherein the volume of a mold cavity expands more than the volume of the optical shaped body in question and a molten thermoplastic resin is injected through an injection molding passage the mold cavity is injected.
- the thickness of the injection molding cavity is at least 55%, in particular at least 80%, in particular at least 100%, of the diameter of the injection molding cavity.
- the Abstehform has a temperature of not less than 100 ° C. In a further advantageous embodiment of the invention, the Abstehform has a temperature of not more than 140 ° C. It is particularly provided that the blank remains in the Abstehform at least 6 minutes.
- the inner diameter of the Abstehform is smaller than the diameter of the lens element. In a further advantageous embodiment of the invention, the inner diameter of the Abstehform is smaller than 70% of the diameter of the lens element. It is provided in particular that the inner diameter of the Abstehform is not greater than 60% of the diameter of the lens element. In a further advantageous embodiment of the invention, the diameter of the Abstehform is not less than 50% of the diameter of the lens element.
- a vehicle headlamp having at least one light source, wherein the vehicle headlamp has a headlamp lens manufactured according to a previously described method.
- the vehicle headlight comprises a diaphragm, wherein an edge of the diaphragm can be imaged by means of the headlight lens or a part of the headlight lens as a light-dark boundary.
- FIG. 13 shows an exemplary embodiment of a final contour shape in a schematic illustration in FIG
- the headlight lens 2 optionally has a light-scattering structure 35 in the interior of the transparent body 3.
- the light-diffusing structure 35 is advantageously a structure produced by means of a laser. In this case, it advantageously comprises a number of punctiform defects, which are aligned in particular to a plane orthogonal to the optical axis 30. It can be provided that the light-scattering structure 35 is annular or comprises annular regions or that the punctiform defects are arranged in rings. It can be provided that the punctiform defects, in particular within the selected structure, are randomly distributed.
- the standard deviation of the gradient of the headlight lenses corresponding to the headlight lens 2 is less than or equal to 0.005.
- the standard deviation of the glare value of the batch of headlight lenses 2 or the vehicle headlights into which the headlight lenses 2 are installed is advantageously less than or equal to 0.05 lux.
- the standard deviation of the value 75R of the headlight lenses 2 or the vehicle headlights, in which the headlight lenses 2 are installed is less than or equal to 0.5 lux.
