Definitions

  • the present invention relates to an optical lens for vehicle headlights, of the type in charge of projecting the light emitted by the headlight bulbs, being applicable to any type of vehicle, be it a car, a truck, a motorcycle , a tractor, a coach, etc.
  • the object of the invention is to provide a lens of very low manufacturing and maintenance cost, with high design capabilities, faster to manufacture, resistant and lightweight which results in a saving of energy consumed by the vehicle, having to move less weight.
  • optical lenses that participate in the headlights used in vehicles to project the light on the roadway are obtained to date in glass or mineral materials, in order to withstand the high temperatures reached by the lamps, either halogen or xenon, without These undergo deformations.
  • optical lens for headlights of vehicles that the invention proposes solves in a fully satisfactory manner the above-mentioned problem based on a simple but highly effective solution, constituting an element of very low manufacturing and maintenance cost, with manufacturing possibilities exceeding of glass, faster to manufacture, resistant and lightweight.
  • the lens that is recommended part of the conventional basic structuring of this type of lens although it could take more complex forms according to different design lines, with the particularity that it is obtained in an organic material, such as plastic.
  • the lens can be materialized in polycarbonate or PMMA, extremely light material, cheap and easy to mold.
  • the lens Given the nature of the lens, it is obvious that it is not intended to be implanted in headlights with conventional lamps, either halogen or xenon, since they would be affected by the heat emitted by this type of lighting source, undergoing deformations, although it is of special application to new-built headlights with new technologies, such as led lighting, or any other technology that may arise in which light sources barely transmit heat, achieving the large number of advantages previously commented.
  • Figure 1 shows a sectional view of a headlight of a vehicle in which a lens made in accordance with the object of the present invention is implanted.
  • Figure 2. Shows an enlarged view of the lens that participates in the assembly of the previous figure.
  • a headlight (1) of a vehicle is shown, with its corresponding parabola (2), in which a light source (3) is established based of LEDs, but which, as previously mentioned, can be materialized in any lighting source that emits little heat during operation, to which a reflective housing (4) is associated, a lens holder (5) that projects the light increasing its light power.
  • the lens (5) is obtained in an organic material, such as plastic, or more specifically polycarbonate or PMMA.
  • This material is extremely light, cheap and easy to mold, so that the geometry presented by the lens (5) in Figure 2, is simply exemplary, being able to mold according to more complex shapes than the glass allows, and adapt to different specific needs, all with a much faster manufacturing process.
