Definitions

  • the present invention relates to a lighting device, of the type that incorporates a light source, either a bulb, a fluorescent, a projector, LEDs, etc., whether for domestic or industrial use, and incorporating a lens for the transmission of the light emitted by the lighting source.
  • the object of the invention is to achieve a minimum loss in the transmission of the light emitted by the lighting device.
  • the loss of luminosity that is to say of luminous flux when a transparent medium of plastic type is transferred, ranges between 8% and 16%, percentage of loss that depends on the type of plastic material used and its thickness, so that in any case this loss of luminous flux leads to a substantial reduction in the light emitted by the initial emitter.
  • the lighting device that is recommended has been conceived to solve the above-mentioned problem, so that, based on the conventional structuring of any type of lighting device such as those previously mentioned, that incorporate a lens for the transmission of the light emitted by source
  • the lighting in question be it a light bulb, a fluorescent lamp, a projector, LEDs, etc., has the peculiarity that the surface of said lens is provided with a non-reflective coating, thereby improving the intensity and accuracy of the light transmitted by the light emitting source, so that the anti-reflective treatment applied to the lens surface will reduce the reflected and unwanted light emitted on the plastic surfaces used in the light emitters.
  • the anti-reflective surface can be applied both to concave lenses and to convex or neutral lenses, as well as to plastic surfaces, transparent surfaces or protective housings through which light passes, with the particularity that in any case the loss of light transmission will range between 1 % and 3%, compared to the traditional 8% to 16% percentage, so that the light emitted by the light emitter will be much higher, and it can be estimated that a lens that carries the anti-reflective surface will emit between 7% and 13 % more light than conventional lenses, logically depending on the materials and thicknesses used.
  • the lighting device can include one or more lenses, in which second case all the lenses will be provided with the anti-reflective treatment on their surface, and whose anti-reflective surface is constituted by multiple very thin layers that are deposited in high vacuum by evaporation of certain substances, producing a series of interferences by which the reflected light is canceled, increasing the transmitted light, thereby achieving an increase in the transmittance of the light and a reduction to minimum percentages of the reflected light.
  • the lens or lenses used may be of organic or inorganic (mineral) material, and the anti-reflective coating that is applied to the surface of the lens may be on one side or both.
  • Figure 1 shows a sectional view of a lighting device made in accordance with the object of the present invention.
  • Figure 2. Shows a sectional view of the lens incorporating the device of the previous figure, showing the different layers of anti-reflective material applied on the surface of the lens in question.
  • the device of the invention can be materialized in multiple ways, starting from the basic and conventional structuring of any lighting device, in which a housing (1) carrying the lighting source (1) is defined. 2), whether of the LED type, fluorescent, incandescent, or any other type of lighting source existing in the market, with the particularity that said housing is topped by its tip in an open mouth, on which at least a lens (3) light distributor.
  • the lens (1) has its surface provided with several layers (4) of a non-reflective material, such that the reflection produced by said lens (1), as a light transmitting element , it is diminished, thereby achieving an increase in the light output emitted by the device itself and a more perfect light beam; all this on the basis that the reflection of light is reduced, due to these layers (5) of anti-reflective material.

Abstract

La présente invention concerne un dispositif d'éclairage, du type de ceux qui comprennent une carcasse de support de la source d'éclairage, de type DEL, ampoule fluorescente, incandescente ou tout autre type d'éclairage existant sur le marché, laquelle carcasse se termine au niveau de son extrémité par une embouchure ouverte sur laquelle se trouve placée au moins une lentille de distribution de la lumière, la surface externe de ladite lentille faisant office d'élément de transmission et de distribution de la lumière et présentant un revêtement antiréfléchissant formé de plusieurs couches fines, réduisant la réflexion de la lumière et augmentant la puissance lumineuse projetée.
