Illuminating glazing with incorporated deflector
Technical Field The present invention relates to a lighting assembly glass, particularly glass assembly for a vehicle, which can emit light in a directional manner. Background Art Known in single or layered assembly of the edge of the glass incorporated into electroluminescent diode module (LED module), so that the light emitted by the LED through the side edge of the glass sheet and into and by its guide until the diffusion element, also referred to as light extraction device. These lighting assembly glass often has environmental the function of illumination. Light extraction device in all directions, in fact, without distinction on the extracted self-illuminating sheet diffusing light. However, in some cases, may be combined is that, even the necessary is to limit diffusion angle of the extracted light. Therefore, for example, in residential areas, when it is desired that the to the particular decorative element when the lighting in order to highlight its, or in the car field, when it is desired that the pair of adjacent to the passenger of the passenger space area for illumination without prejudice to other passengers, and especially when the driver. Can be envisaged, of course, by being fixed to the illumination on one side of the sheet material, adjacent to the diffusing element is extracted from the deflector to the (déflecteur) diffusing light waveguide sheet material for directional. However, from an aesthetic point of view, such a solution will not too satisfactory, because of this the opaque deflector glass prosperous suddenly from the assembly, and when the light source is extinguished the transparency of the glass so that the assembly and flatness to experience some downstaged. Content of the invention The invention is based on the idea of such: the assembly of the glass at the center of the function of integrated deflector, this is achieved by the assembly of the glass in a limited area, the illumination of one of the principal plane of the sheet material is configured to bulge, which comprises is equipped with a reflection interface and can make the optical directional the geometric pattern. In order to ensure that the zone effectively play the role of the deflector, the reflection of light is should be very the majority of the mirror type. The term "reflection interface" specified in the -Either in the lighting of contact with the sheet material and the interface between the solid medium, -Or is connected to the illumination plane of the sheet material and structure of the contact structure with the plane of the interface between the solid medium; in order to the light from the lighting device can be freely transmitted to the link of the sheet material in the structure of the plane, the plane structure should be greater than or equal to the refractive index of the lighting sheet material of the refraction index. The purpose of this invention more particularly is a glass illumination to assemble, which comprises -refraction index n1 of glass sheets 1st, with the same principal 1st, 2nd main surface and side edges; -With the 1st 2nd contact adhesion of the sheet material of the principal polymer transparent film, the film has a refractive index n2 <n1; -Light source, preferably for an electroluminescent diode module (LED module), 1st glass sheet located in a place that is opposite to the side of the, The assembly is characterized in that the fact: 1st 2nd main surface of the glass sheet equipped with a region of the reflecting protruding or covered with a plane and transparent flat structure, which has a refraction index n3 is greater than or equal to n1, is equipped with a reflective convex. The purpose of this invention also lies in the vehicle, preferably includes such a lighting assembly for motor vehicles of the glass, the glass preferably the illumination to assemble a part of at the top of the vehicle. Play the role of deflector the scope of the area of the (étendue) preferably is substantially smaller than the 1st range of the sheet material. Advantageously said 1st the scope of the of the sheet is less than 30%, preferably in the 1 and 25% between, particularly in a 1 and 10% between. The assembly of this invention the glass can be a single glazing, preferably by quenching is made of glass, or laminated glazing, which comprises in a known way, by means of a layered insert and attached to each other at least two sole piece material. In a preferred embodiment, glass assembly of the present invention therefore also includes the 2nd glass sheet material, with the same principal 1st, 2nd main surface, and the lateral, polymer transparent film layered insert therefore play the role of the glass sheet with the 1st and 2nd main surface of the glass sheet with the 2nd and 1st main surface adhesion contact. When the polymers of the transparent film is a layered member is inserted, which can be used for this purpose is usually formed of a material, as long as its has less than 1st optical index of the glass sheet (n1) optical index n2. As an example can be quoted completely a suitable material: poly (vinyl butyral) (poly ( de vinyle butyral)), it has about 1.48 optical index, that is to say optical index of less than typical close to 1.5 optical index of the inorganic glass. It is important to point out that, in the assembly of the glass in the following description, term "1st sheet material" will always be in its side edges as may be specified by one or a plurality of light sources illuminating the glass sheet. 1st sheet material or illuminating the sheet material is preferably inside of the vehicle or building that of contact. The assembly of this invention in two sheet of glass each having a side edge and two principal plane. Aimed at being oriented so as to faces the vehicle passenger space surface or towards the interior of the building is referred to as "principal 1st", building or vehicle and the outside of the passenger space surface is referred to as "principal 2nd". The assembly of this invention the glass have not been integrated on the body of the vehicle is not in the integrated when a wall of the building, the term means that the only 1st principal plane of the two sheet materials oriented in the same manner. As has been explained in the introduction, the reflection protrusions should have a low roughness, so that the reflection is substantially specularly types of. The degree of roughness of the reflection interface and are chosen in order to make the intensity of the light emitted by the system the half-height of the total width of the angular distribution preferably is included in the 30° and 60° between. Reflection of the degree of roughness of the larger will therefore has a nature is more diffuse reflection and so have more relaxed angular distribution, on the contrary, the reflection protrusions of the lower with the degree of roughness of the nature of light reflection of more mirror in the mirror direction and thus has more tightening around an angular distribution. The angular distribution of the intensity of the light emitted through the angulation luminosity method is a measurable, the luminosity method states the angulation technical personnel in this field is well known and for example described in the International Commission on illumination in the reference document: "CIE 070-1987 Intensity The Distributions Measurement Luminous Absolute of" and "CIE 121-1996 Luminaires The Goniophotometry Photometry and of". In order to light the width of the angular distribution of the intensity is between the value of the seek, is can be envisaged, in replacement of or in addition to the degree of roughness of the reflection protrusions, in 1st sheet material, the sheet material in the 1st or 2nd 1st main surface is adjacent to the principal plane of the reflection protrusions of the textured area of the diffusing element is arranged. The potential of the diffusing element and in addition present such aesthetic advantages: the 1st 1st of the sheet material through which the principal equipped with the reflective interface regions of the observer the texture of a masking reflective interface. The degree of roughness of the independent of the reflection interface, can define the height of the bulge or depth, it is equal to the highest and most of said bulge the distance between the low points. Reflecting the height of the bulge is included in the 5 m and 1 mm between, preferably in the 10 m and 500 the between m, particularly in a 20 and 100 the between m. Reflection protrusion may be a 1st 2nd main surface of the glass sheet of a district. However, is not easy to manufacture the limited one of its surfaces included in the area is relatively too deep in the protruding glass sheet material, with said bulge oriented in a proper manner and in order to make the sufficiently smooth the surface of the mirror reflection can be realized. Such a projection can be, for example, by laser etching to create. Notably through the more easily is applied on a surface of glass sheet comprising such of the pre-formed flat structure and create reflective convex. The transparent flat structure can be composed of plastic material made of (organic polymer) membrane, is preferably made of poly (ethylene terephthalate), polycarbonate, poly (methyl methacrylate), polystyrene made. This textured through the convex part of the polymer film is available on the market, and for example can be cited by 3M Vikuiti commercial film Company? Image guided film II ( Film Directing Image). Can also be through in a known way through the sol-gel on 1st 2nd main surface of the sheet of material is deposited on the surface of the silica-based inorganic or organic-inorganic coating of the formed including appropriate transparent flat structure. The sol can be applied during the curing stage of having negative convex surface in such a coating is formed on the surface of the protruding, WO2008/14322 for example, in the manner described in. In order to be able to play the role of the optical deflector, protruding should be is a reflecting interface. Understanding of the invention in a reflection interface for reflecting the visible light of at least 50% of the interface. The protruding interface preferably reflecting visible light of at least 80%, in particular at least 90%. Interface can be, for example, by reflective properties of the surface of the sheet material in the 2nd or transparent planar structure is deposited on the boss of the reflective coating, preferably a metal layer, in particular silver, copper, aluminum, gold, nickel or chromium is obtained by the layer. Convex reflection properties also can be attributed to the fact that such: polymer transparent film (with the protruding contact) refraction index n2 index of the glass sheet is less than 1st n1 or less than the index of the plane structure n3. [...] -descarte (Snell-Descartes) law (n1 sinθ1 = n2 sinθ2) the incident angle can be calculated θ1, more than the incidence angle θ1, light is different optical index of the interface between two kinds of mediums total reflection (θ2 = 90°). Index of large difference Vietnam , θ1 is small, that is to say also the less light needs to be almost horizontal-injection in order to be of interface reflection. In the present invention, index n2 index of the glass sheet than 1st n1 or transparent planar structure of the index n3 preferably small at least 0.02, preferably at least 0.1. Finally, solution 3rd, similar to the former one, the protruded through the coating and depositing a low index of reflection of the said bulge, the low index coating has the index of the glass sheet than 1st n1 or better than the index of the transparent plane structure n3 small at least 0.02, preferably at least 0.1 refraction index n4. Advantageously include reflective projection is composed of a plane or curved surface, a plurality of geometric pattern. It is preferably on the law of geometric pattern with repeating convex, that is to say, basically has the same shape and is substantially the distance each of the geometric pattern. As a rule an example of the reflection protrusions (Fresnel) lens type Fresnel may reference the convex or Fresnel prism types of projections. Fresnel prism types of projection is particularly preferred. Fresnel prism is a series of constant-angle of the small size of the prism. These prism in parallel beside each other in the vicinity of the way and is arranged. Figure 3A is a perspective view of the seven straight individual prism form of the typical Fresnel prism. Figure 3B interesting show the variations of the Fresnel prism, wherein the projection of the individual prism has an arc shape. In the present invention the glass in the assembly of the lighting, the projection of the individual prism is preferably substantially parallel to the 1st illumination of the side of the glass sheets. Here "substantially parallel" understood as: these prism, when when they is straight, with the side edge formed is less than 10° acute angle, or for the purposes of bending prism, such as in Figure 3B of the, the tangent of the curve with the 1st forming the side edge of the sheet material is less than 10° acute angle. As is well known to, is equipped with a protrusion or protruding bearing the plane structure of the shape of the region independent of the shape of the prism. In fact completely may be envisaged include the circular area of the prism, or on the contrary by the prism a of the rectangular shape of the zone. Fresnel prism therefore comprises an inclined surface of the prism and the substrate of the glazing and the general plane of the surface of the substantially vertical. In order to make the Fresnel prism can effectively play the role of thereof as a deflector, Fresnel prism of the reflection inclined surface should be oriented toward the light source, such as the following with reference to the Figure will be explained in detail. When the deflector is not situated directly protruding 1st 2nd main surface of the glass sheet but is applied at the 2nd in the main on the surface of the transparent plane structure, it should be noted that light emitted from a light source by the 1st sheet material guide and the light can be freely into the transparent plane in the structure. Therefore, the transparent planar structure should be in its and is equipped with a reflecting protruding opposite to the surface on the entire surface of, and 1st 2nd contact main surface of the sheet material. Contact interface should be non-reflective. The non-reflected can be by noting the nature of the contact interface has a refractive index substantially free from n5 <n1 material, and, in particular, from air (nair = 1) to obtain. With close to can be with the aid of n1 of the index of refraction of the transparent adhesive to attaching such as transparent plane structure. As to the transparent plane structure, and can also be used in the thermoplastic polymer of the sheet material before contacting with the 1st heating the polymer, is at least partially straight to its softening point. There is also another possibility lies in: RIM through the monomer mixture of (reaction injection-molding), its lead to the thermosetting polymer is formed in situ, so as to form a transparent plane structure. The invention therefore makes it possible to in the absence of the usually used in the technical field under the condition of any of the diffusing element from the 1st waveguide extraction of light sheet. No such diffusing element of the glass in order to assemble the performance improvement of the light efficiency. Glass assembly of the invention hence, advantageously no light-diffusing element. However, for aesthetic reasons, can be envisaged is the 1st 1st piece of sheet material or material fit the 1st or 2nd on the principal, proximate to include a reflective convex textured diffusing element is arranged with the region. For obvious reasons, this component should have a sufficiently low ambiguity (haze) in order to make the intensity of the light emitted by the system the half-height of the total width of the angular distribution is included in the 30° and 60° between.
