Definitions

  • JP 11038232 describes a transparent resin with particles intended to create a diffusing layer on a light screen, sifting it, achieving the effect that produces for example an acid or glazed glass sheet.
  • coatings formed by layers of paint designed to transmit and diffuse light radiation are not known.
  • the present invention proposes a solution to illuminate an object, through a new coating whose physical-optical properties allow it to create a diopter formed by the coating and the air that allows to transmit a radiation of light and diffuse it from the surface of the painted object.
  • a light source (2) After applying this coating (1) (figure 1) on an object (5) (figure 1), so that it illuminates, a light source (2) will be activated (figure 1) that transmits the radiation to the interior (3) (figure 1) of the coating.
  • This source of electromagnetic radiation can have a wavelength range from 50 micrometers (infrared) to 200 nanometers (ultraviolet).
  • the coating will consist of at least one paint layer of polymeric base material, silicone, polyurethane, fiberglass, aerobic polymer, acrylic resin, polyester, vinyl or epoxy, with a light permeability greater than 80% and with a refractive index between 1.2 and 1.9.
  • the diopter formed by the coating and the air allows the critical angle of reflection not to be exceeded.
  • the diffusion (4) (figure 1) of the exterior light can be achieved with different coating characteristics.
  • the modification of surface roughness from 10 to 300 micrometers acts by generating a change in the radiation exit angle, exceeding the critical index of refraction and thereby varying the amount of diffused light.
  • diffusion abroad can be achieved by anisotropy of the coating, generated by the addition of micro or nano particles (6) (figure 4), of nitrides, carbides, oxides such as silicon oxide, titanium, zirconium, cerium, metal salts, and halogenated derivatives, since the addition of these components modify the physical-optical properties of the coating such as the refractive index, the reflection index, the attenuation and the light permeability. Causing that part of the light transmitted through the interior of the coating changes its angle of refraction and diffuses to the outside (4) ( Figure 1, 2, 3,4 and 5).
  • Another way to vary the coating index is the inclusion of charges or additives such as AsGa, KH 2 P0 4 , KD 2 P0 4 or L ⁇ Ta0 3 , whose refractive values change when an electric field is applied.

  • This layer is between the object to be coated (5) (figure 2) and the transmitter layer (8) (figure 2) in order to improve the efficiency of the light source transmission. In turn, this layer avoids the physical-optical discontinuities of the base object, homogenizing it to a known value.

  • Ultraviolet radiation is transmitted along a zigzag path (3) (figure 4). And its diffusion will be the result of the anisotropy of the second layer of paint created with the addition of metal oxide particles.

Abstract

L'invention concerne un revêtement composé d'au moins une couche de peinture émettrice. Ces couches de peinture génèrent un dioptre avec l'air, dont l'indice de réfraction peut être ajusté en fonction de leur composition et de leur fini de surface. L'application d'une source de lumière sur un objet peint à l'aide de ce revêtement permet de générer l'éclairage de sa surface indépendamment de sa géométrie. La présente invention peut s'appliquer dans le secteur de l'éclairage, de la signalétique et dans le domaine médical hospitalier.
