Definitions

  • Light scattering element in particular for decorative lighting purposes
  • the invention relates to a light scattering element, in particular for decorative lighting purposes.
  • Light scattering elements are known in a wide variety of forms. For decorative lighting, it is desirable to use refraction and / or reflection effects to produce the most interesting light patterns either on the light scattering element itself or on reflective surfaces, for example on walls or the like. Conventional light scattering elements usually contain reflectors, light guides or solid bodies for generating the desired reflection or refraction effects.
  • These solids mostly consist of glass, ceramic, plastic or surface-treated metal and have regular geometric shapes or microscopically irregular structures, e.g. the shape of regular prisms.
  • the solid bodies either consist entirely of a corresponding reflective material or are coated with such a material.
  • the invention has for its object to provide a light scattering element, in particular for decorative lighting purposes, with which extremely interesting lighting effects can be achieved in a simple manner.
  • macroscopically chaotic or quasi-chaotic refraction and / or reflection planes creates the desired interesting lighting effects.
  • macroscopically chaotic is used in the context of this application in contrast to the known microscopic irregular structures, e.g. roughened surfaces or very small irregular bodies, such as ground glass.
  • Quasi-chaotic is understood to mean an irregularly appearing structure, even if it should have a certain regularity, but which the viewer no longer recognizes as such.
  • the light scattering element consists of a transparent envelope filled with a liquid transparent medium, which is macroscopically chaotic or quasi-chaotic in shape or has a correspondingly irregular outer surface.
  • a liquid transparent medium which is macroscopically chaotic or quasi-chaotic in shape or has a correspondingly irregular outer surface.
  • Such light scattering elements can also be produced with relatively little effort if they are of relatively large dimensions.
  • flexible sheaths offer the advantage that when a plurality of such light scattering elements are combined, they can be placed in a rigid sheath, for example due to the flexibility, it is easier to "interlock” and better adapt to any shape of the interior of the case. This results in more compact structures that also produce more interesting lighting effects.
  • Flexible light scattering elements can also be deformed with light during the irradiation or illumination and thus produce corresponding effects.
  • the casing consists of a flexible film, the casing being, for example, only imperfectly filled with the liquid medium and by at least partially removing the air (for example by suction or pressing) from the remaining volume of the casing before it is sealed Closing an irregular deformation of the shell can be generated.
  • the deformation of the casing can be generated before or after it is filled and closed by a mechanical action.
  • the desired deformation can be generated with additional heat and at the same time folding, folding or crumpling the casing.
  • the thickness or the material of the casing can be selected such that the shape is maintained despite the internal pressure due to the filling with liquid.
  • the shell can also be covered with a transparent material, for example by pouring transparent polymers over it.
  • a casing consisting of a film can be produced by welding two or more, preferably planar, film elements.
  • two or more foils stacked on top of one another can be flat at the edges are welded to one another, initially leaving a filling opening for the liquid medium.
  • the optionally multilayer bag thus produced can be mechanically deformed in order to obtain an element which achieves the desired refraction or reflection effects when illuminated.
  • a sleeve designed as a flexible film can also be produced by film blowing.
  • a mold is usually used into which a plastic bubble is blown by generating a sufficiently high internal pressure. Compared to welding several film elements, this method offers the advantage that the casing has practically no externally visible seams.
  • the sheath can, for example, also be produced from film tubes, a tube section being sealed at the ends.
  • a strongly deformed, preferably crumpled film is arranged inside the casing.
  • This film will usually be made transparent, but can of course also consist of a reflective material.
  • a transparent film must be used, the refractive index of which is different from the refractive index of the liquid in the shell. This is because refractive effects only occur when light is transferred from a medium with a first refractive index to another medium with a second refractive index that is different from the first refractive index.
  • a (partial) reflection can also occur with such a transition.
  • the light scattering element according to the invention can also consist of a solid body consisting of one or more flexible materials, the outer surface of which is macroscopically chaotic or quasi-chaotic. Rubber-like silicones are suitable for this, for example, which remain elastically flexible even at temperatures from -50 ° C to + 200 ° C. Such elements are easy to manufacture by casting or injection molding. The material can be placed in an intermediate mold, which is re-shaped after partial curing. Due to the flexibility of such light scattering elements, the advantages mentioned above are again achieved.
  • the shell has a substantially smooth outer surface and the desired refractive and / or reflection effects are achieved by elements arranged inside the shell.
  • This can be a strongly deformed, preferably crumpled film and / or one or more light scattering elements according to one of the above embodiments of the invention.
  • this shell can also be filled with a liquid medium.
  • the outer shell is preferably made of a substantially rigid material. In this way, there is the advantage of sufficient stability against external mechanical influences and against the internal pressure of the elements or liquids provided therein.
