Definitions

  • the present invention relates to a light transmission and distribution device applicable to vehicle headlights, constituting what is considered as an optical system in charge of transmitting and distributing the light emitted by light emitters such as lamps. or light bulbs, leds, etc.
  • the object of the invention is to provide an improvement in the transmission and distribution of light with an optical device, easier to manufacture, with lower manufacturing cost, with a significant weight reduction, and to reduce to a minimum amount the units that come out with default. By reducing the weights we also reduce the weight of the vehicle making it lighter and need less energy consumption.
  • the headlights of the vehicles include a lens within what is the optical system responsible for transmitting and distributing the light emitted by the headlight lamp, so that these lenses are currently too thick and too heavy, having problems at the time of being manufactured, resulting in manufacturing rejections greater than 50%, since due to the thickness too thick, it happens that when the material cools until the lens solidifies completely, it undergoes unwanted variations in its surface, appearing even bubbles inside and certain opacifications that decrease or alter the light transmittance, so the transmission and distribution of light is not optimal
  • the light transmission and distribution device applicable to headlights of vehicles comes to solve the problem set forth above, based on a simple but effective solution.
  • the device of the invention is based on the fact that instead of using a single lens, as traditionally occurs, two or more lenses of smaller thickness are incorporated, these being very easy to manufacture and with a very low number of rejections, with a lower weight of the set compared to optical systems that use a single lens, reducing the weight between 30% and 75%.
  • the lenses used in the device of the invention can be of mineral material such as glass, or in organic material such as plastic, (polycarbonate or PMMA, for example). Mineral lenses and organic lenses can also be used in combination, and these can be complete or sections of lenses, or even Fresnel-type lenses that at the end of the day are optical lenses, or lenses included in a piece or that are part of it.
  • the lenses used can be concave, convex, neutral or mixed, and optionally be able to include prisms or diaphragms or even other elements that were necessary within the optical system to be implemented.
  • an optical system is obtained, that is to say a light transmission and distribution device that will provide more precise and exact illumination than those offered by devices that use a single lens, the manufacturing cost of the lenses according to the invention being much lower than the price of the lenses currently used, with a lower weight of the optical system as a whole and with a much lower number of rejections in the manufacture of the lenses, with the particularity that if a lens is defective, there is only reject this lens and be able to keep the remaining ones, something that does not happen in conventional lenses where, as this is unique, if rejected, the entire optical system is rejected.
  • the device can be fixed, that is to say that the participating optical lenses can always maintain a constant fixed distance from the light source or light emitter, or they can even be mobile, varying some of the distances that exist from any of the lenses relative to the light source.
  • Another advantage of the device of the invention is that less space is needed inside the projector headlight itself.
  • Another advantage is that the lens or lenses when made in organic material are injected in a single injection cycle, because their thicknesses fall within the parameters for this type of manufacturing.
  • the lens or lenses used in the device can be of the same or different diameter and manufactured independently and then placed in their corresponding place, or that all of them are part of the same set or piece.
  • Figure 1 shows a schematic representation of what is the light transmission and distribution device applicable to headlights of vehicles object of the invention, two lenses of different diameter and the corresponding light emitting focus being seen.
  • Figure 2. Shows a view of the light transmission and distribution device applicable to a headlamp in which two lenses participate.
  • Figure 3. Shows a schematic representation like that of the previous figures, but in this case forming a unique set of the lens or lenses, with the light emitters, both lamps and LEDs.
  • the inventive device is intended for application preferably in the headlight (1) of a vehicle, which includes one or more light emitters (2), as shown in Figures 2 and 3, beacon which, as is conventional, will include a lens for the transmission and distribution of the light emitted by those light emitters (2).
  • the novelty of the invention is that the transmission and distribution of light is carried out by means of at least two lenses (3 and 4), which can be of the same or different diameter and can be materialized in an organic material or in a mineral material or mixed application, so that in any case the light emitted by the light-emitting bulb (5) is distributed evenly and efficiently through the lenses (3 and 4), which can be manufactured with a thickness much less than required by conventional lenses applicable to vehicle headlights.
  • the lenses (3 and 4) can be independent elements and manufactured in isolation and then placed inside the optical system assembly, or form a unique assembly with the optical system itself and the headlight as a whole, as shown in the figure 3.
