Definitions

  • the invention relates to a decorative element, in particular for the fields of lighting technology, Jewelry, furniture or the like.
  • decorative element is hereby wide to understand and concerns in particular the use of components, objects and Figures for use in the arts and crafts sector.
  • the present invention is therefore based on the object, in particular for the application Lighting technology, jewelry and furniture to provide a decorative element, which is very attractive in its peculiarity and at the same time not too high in costs Comparison to the attachment caused.
  • the decorative element according to the invention is a ceramic Material that consists of a recrystallized silicon carbide.
  • Ceramic Materials are used as so-called refractory materials in the industry, wherein here, in particular, the material properties such as hardness, strength, thermal shock resistance, Corrosion resistance and resistance to mechanical wear uses. Typical of the material is that it does not only have these properties at room temperature, but even at very high temperatures up to 1500 ° C, which is why he to the so-called refractory materials is calculated.
  • the production of the decorative element of recrystallized silicon carbide takes place here made of very fine-grained silicon carbide powder to provide the desired crystal structure to get great brilliance and glitter effect. This is done with water and small amounts recycled organic binder to a slip.
  • This slip will be appropriate conventional ceramic molding technology is poured into plaster molds and preserved therein a form determined by the designer or designer. The plaster mold evades the Schlicker water and it creates the so-called "greenhorns". After a reasonable Time then the plaster mold can be opened and the still "green” component removed. After a subsequent drying process, the component can then if necessary still a mechanical processing similar to the metal technique by drilling, Turning or milling are subjected to make the decorative element accordingly.
  • the burning of the decorative element takes place in particular in electrically heated ovens Temperatures of 2400 ° C. The presence of oxygen in such ovens should thereby be avoided. Rather, the furnace space is advantageous during the fire of recrystallizing silicon carbide with inert gases such as nitrogen, helium or argon flooded.
  • the fired components of recrystallized silicon carbide gain their strength a recrystallization of finest silicon carbide grains (less than 5 microns) and attachment to larger Silicon carbide grains. This typically occurs on the surface of the components pronounced crystalline structures of idiomorphic silicon carbide crystals.
  • the firing program produces crystals of silicon carbide on the surface of the components in a size of about 0.1 to 5 mm, but typically 0.2 to 1 mm. These surfaces are black from the basic tone and reflect by light in a variety of ways of the innumerable silicon carbide facets, that is, these facets are in the Able to reflect incident light, giving the surface a glittering appearance receives.
  • This glittering effect occurring when the light is incident is advantageous in the present Used invention, for example, in a lighting device with at least a luminous body such as a lamp, in such a way that the recrystallized Silicon carbide existing decoration element and the luminaire facing each other to be ordered.
  • the illuminated by the lamp decoration element speckles as a result of the refraction of light, the multitude of crystals in a visually very pleasing way Light, creating a decorative very beneficial sparkling surface with great brilliance.
  • the decorative element can in this case be arranged and formed in a variety of ways, particular part of the lamp, such as the lamp parts, lamp covers, Blinds, standing body, support feet and the like.
  • a trained floor lamp with a lampshade which attenuates the direct light emission of the lamp to the viewer, and one as an arc segment formed foot part of recrystallized silicon carbide appears as far as attractive, as the directly illuminated by the lamp foot part reflects this light and This gives a glittering surface.
  • a decorative element according to the invention as an independent unit place and apply a separate light emitter so that this is for yourself alone sparkles.
  • the attachment is both in a building and in the outdoor area possible.
  • the decorative element of the invention be provided, in such a way that this with its visible surface of the person wearing the person facing away from the side is arranged. This ensures for example, incident solar rays on the recrystallized silicon carbide surface strike and cause their glittering.
  • the piece of jewelry can be used as a pendant, Brooch, ring or chain be formed.
  • Another area of application is in the furniture industry, for example in the design a table in which locally limited in the table top an inventive Decorative element or the table top to be covered with a corresponding layer can. It is expedient to form the decorative element area and for example in the middle or at the edge of the table top, leaving one above the table hanging table lamp with its rays of light directly applied to the decorative element, making this a glittering element.
  • the visible surface of the decorative element according to the invention may be designed such that different color effects, such as so-called tarnishing, come into effect.
  • color effects are obtained by treating the decorative element of recrystallized silicon carbide completely or partially oxidizing in another furnace after the actual production firing (electrically, 2400 ° C. without oxygen presence) in another furnace, whereby the surfaces oxidize in the presence of oxygen, so that thereby extremely thin layers SIO 2 arise, which have color effects as so-called temper colors to effect.
  • the floor lamp 1 shown in a perspective view in Fig. 1 has a foot part 2, the at the same time serves as a decorative element.
  • the foot part 2 has in the middle a stand 3, to whose free end a lampshade 4 is fixed, in which a lamp 4 'as Luminous body is located.
  • the foot part 2 consists of recrystallized silicon carbide, the visible surface 5 at incident Light - indicated at 6 - glistens - indicated at 7 -, since the facets of the crystal Recrystallized silicon carbide, the incident light 6 of existing in the lampshade 4 Reflect light bulb.
  • the decorative element in its manufacture To give by tarnishing also a different color than black, about red or brown.
  • Such an arrangement is also good in the outside area conceivable, for example, in a Garden in the evening to get special lighting effects.
  • a jewelry tag 12 is shown in Fig. 3 as a further embodiment, consisting of an enclosed decorative element 13 made of recrystallized silicon carbide which, for example, begins to glitter in incident sunlight, as indicated at 13 is. It is important here that the visible surface designated by 14, i. the reflective one Side, is arranged such that this particular on the jewelry-bearing Person facing away to come, so for example, the sunlight through the Reflection property of the jewelry surface can come to its full advantage.
  • the size of the crystals is in the range of 0.1 to 5 mm, which is the reflective As regards area, preferably in the range of 0.2 to 1 mm.
  • the crystals made of silicon carbide platelet-shaped, namely hexagonal, wherein the Size of the wrench size, so the distance between the opposite parallel surfaces of the Hexagon, in the range of 0.1 to 5 mm, in particular 0.2 to 1 mm.
  • the use of the decorative element according to the invention of recrystallized Silicon carbide has no limits, especially since its shape is arbitrary can be, because the blank is made in a plaster mold and here a diverse Design is possible.
