    专利说明:

    The invention relates to a faceted transparent object, such as e.g. Decorative or gemstone, with a front and a back, wherein the back is at least partially provided with a light-reflecting layer, and with a light source for illuminating the object.
    Facetted transparent objects are used for example as decorative or gemstones and are made of so-called gemstones or minerals, the cut produces a variety of facets, which determines the shape of each gemstone. The cut is intended to enhance the shine of the stone and to highlight the inherent optical effects of the stone through multiple reflections and refractions of light entering the object. The mentioned gemstones are also made of glass, in particular crystal glass, and are then referred to as "crystals." Furthermore, artificial decorative or gemstones are also known from acrylic glass or the like.
    The aesthetic quality or brilliance of a faceted decorative or gemstone depends on the reflectivity of the object, which in turn is determined by the refractive index of the material. High quality decorative and semi-precious stones, such as those made of diamond or high-grade colorless glass, have a sufficient reflectivity. In particular, in artificial jewelry or decorative stones made of acrylic glass, the brilliance is insufficient. In the brilliance, a distinction is made between the external brilliance by direct reflection on the surface of the object and the internal brilliance by the reflection (total reflection) on the inner surfaces. For materials with poor reflectivity, the
    Brilliance, in particular the internal brilliance, by applying a light-reflecting layer, such as e.g. a mirror foil to be raised at the back of the object.
    It is known that illuminating a faceted transparent object, such as e.g. a decorative or gemstone whose aesthetic appeal increases, especially when the natural ambient light is dim or when darkness prevails. For illuminating the object, an artificial light source can be arranged in the object. The arrangement of an LED in a recess of the object is described, for example, in US 2001/0055205 A1 and in EP 1347234 A2. However, these patents require an object having at least one bore / recess, as is the case with pendants or beads.
    In the jewelry industry, however, objects are now often used with a cut that does not provide a bore / recess, such as the diamond cut and so-called Fancy Cuts. However, if these cuts require a mirror layer underneath the edge strip due to a low refractive index of the material, the attachment of an LED poses a problem. The LED can not be mounted underneath the edge strip since the mirror layer does not allow light coupling here. The LED can not be mounted above the Rondiste, as this would cover part of the visible gemstone.
    Furthermore, the light coupling on the Rondiste is problematic because it often has a small height, and further the light spot on the opposite facet is reflected directly into the eye of the observer, whereby the aesthetic quality of the illuminated object is impaired. When illuminating a faceted transparent object, one endeavors to achieve the most homogeneous possible illumination. The aim is to achieve the effect that the object radiates from the inside, without being able to recognize a concrete light source when viewed from outside. In particular, the recognition of a punctiform light source would detract from the beauty of the overall object and should therefore be avoided as much as possible.
    The present invention therefore aims to improve a faceted transparent object of the type mentioned in that a homogeneous illumination with artificial light succeeds without the light source can be located from the outside when viewed externally and without the aesthetic appearance of the usual Consideration of the gemstone in daylight would be impaired.
    To achieve this object, the invention essentially provides, in the case of a faceted transparent object of the type mentioned initially, that the object has a heart-shaped cut and the light source is arranged in the plane of symmetry of the object. It has surprisingly been found that the choice of a heart shape of the object allows an extremely homogeneous illumination when the light source is arranged in the plane of symmetry of the object. The reason for the advantageous optical effects of the invention lies at least partly in the fact that the heart shape, in addition to its symmetrical shape, has the peculiarity that no facet is arranged at the point opposite the light coupling in the plane of symmetry, via which the incident light directly reflects the viewer can be, whereby the light source would be recognizable as a punctiform lighter area. Furthermore, it is surprising to note that the inventive design leads to an illumination of the object up to the edge of the object, even if a small-sized, point-shaped light source is used.
    It is preferred within the scope of the invention if only a single light source is provided for illuminating the object. The illumination is achieved by. Incorporate the light of only a single light source either at the top or bottom of the plane of symmetry.
    A preferred embodiment provides that the light source is arranged between the two curves of the heart shape. On the one hand, this allows a protected arrangement of the light source, since the notch at this point is typically wider due to the indentation towards the center of the object. On the other hand, this results in an advantageous light coupling and homogeneous light distribution, wherein also in the two curves of the heart shape possibly behind the light source areas due to multiple reflections in the interior of the object can be supplied with light.
    Another advantage of this arrangement of the light source is that the light-reflecting layer remains intact at the back of the object. Likewise, in this arrangement, the front of the object remains free of Anoder internals, so that the aesthetic appearance is not affected by the usual viewing from the front.
    Alternatively, the light source may also be arranged in the region of the tip provided at the lower end of the heart shape, to which the side surfaces of the heart shape converge. In the case of the arrangement of two light sources, a light source may be provided between the two curves of the heart shape and the other light source at said tip, both light sources being arranged in the plane of symmetry of the heart shape.
    The heart-shaped cut is preferably formed such that the facets of the heart-shaped cut converge at the point opposite the light source to a point arranged in the plane of symmetry. As a result, direct reflections of the incoming light on the reflective backside layer towards the viewer are effectively avoided.
    Advantageously, the light source can be fixed to the surface of the object, so that a direct coupling of light into the object allows and the scattered light component is minimized.
    The light source is preferably formed by an LED, so that a corresponding miniaturization is ensured, which allows an arrangement of the light source, for example, between the two curves of the heart shape even with correspondingly small versions of the object.
    The wavelength or color of the light emitted by the light source can basically be chosen arbitrarily. Preferably, white light is provided. The illumination can be characterized by a constant introduction of light or an at least temporarily pulsating introduction of light. Different lighting effects can be achieved. For example, the effect of a constant white illumination from a pulsating colored, e.g. red, light superimposed by (a) attaching either a white LED at the top between the two curves of the heart shape and a colored LED at the lower spigot end (or vice versa), or (b) the white LED next to the colored LED either at the top between attached to the two curves of the heart shape or at the lower spigot end. Furthermore, (c) the monochrome LED can be replaced by an RGB LED, allowing a variety of color combinations.
    Preferably, the object is made of glass or acrylic glass.
    The invention will be explained in more detail with reference to an embodiment schematically illustrated in the drawing. 1 shows a front view of the object according to the invention, and FIG. 2 shows a perspective view of the object according to FIG. 1.
    In Fig. 1, a transparent object 1 of e.g. Glass or acrylic glass whose surface has a plurality of facets 2. The object is heart-shaped and therefore has a heart-shaped cut. At the back 3, the object 1 is provided with a mirror film (not shown). The object 1 has a symmetry plane 4.
    The ratio of height to width of the heart-shaped object 1 is preferably between 0.5 and 2, wherein the height in the plane of symmetry 4 extends and the width is measured perpendicular thereto.
    In the plane of symmetry 4, a light source 5, in particular an LED, is arranged between the two curves of the heart shape. The light source 5 in this case has a light emission in the direction of the object 1 or into the object 1, wherein the light entering the object 1 is repeatedly reflected on the inner surfaces of the facets 2 and is distributed homogeneously over the entire extent of the object. The light source may be attached to the exterior surface of the object 1 by conventional means, e.g. with the help of a transparent adhesive.
