Abstract

method for creating aesthetic lighting effects in artistic Installations, in particular in an auditorium, a diffuser (2) or several scattered bodies combined into an ensemble (1) illuminated by one or more light sources (3) and the Scatter scattered light (5) into a darkened auditorium, thereby characterized in that as a scattering body (2 pieces made of melted and broken alkali silicates ("Water glass") are used.

Description

  • The The invention relates to a method according to the preamble of the claim 1 and an apparatus for carrying out the method.
  • It is known to illuminate game stages in particular of theaters by means of a variety of headlamps, which are interconnected depending on the set to groups. By combining, by intensity fluctuations or by movements of the headlights, a variety of aesthetic effects can be achieved. It is known, for example, from German Patent No. 629765 to produce lighting effects simulating flames of a fire, for example, by irregular illumination of objects or by backlighting. Furthermore, aesthetic lighting effects are also produced indirectly by the refraction and reflection of light on planes or regularly curved surfaces. In addition to such mirrors, in practice, even small bodies whose boundary surfaces reflect (scattering body), in particular artificial snow and the like, are used. Such diffusers are for example from the DE 2657166 A1 and the DE 4003923 A1 known.
  • adversely The known method is that they are very expensive and therefore are expensive. Furthermore has not been able to manage the effect of naturally irregular, shining light as, for example, glowing incandescence aired in for the Viewers more amazing To evoke authenticity.
  • task It is therefore an object of the present invention to provide a method that the viewer with artistic Installations the impression of a brilliantly radiant object of greater naturalness conveys and especially aesthetic Achieved lighting effects. At the same time it is the object of the invention a device for carrying out of the procedure.
  • These The object is achieved by the method having the features of the claim 1 solved.
  • The Another object is achieved by the device according to claim 5.
  • advantageous embodiments the method according to the invention and the device according to the invention are in the subclaims listed.
  • The Invention is especially for the production of set designs in theaters or opera houses suitable.
  • Especially advantageous to the stage lighting according to the invention is that it achieves amazing effects with simple means. Especially are the scatterers made of water glass readily available, economical to produce and process by known methods. For lighting the scattering body made of water glass can u. a. also in the stage equipment existing headlamp or conventional light bulbs are used.
  • By the stage lighting according to the invention, especially by the lumpy and broken scattering bodies made of water glass, used individually or combined into an ensemble be able to produce novel light reflections, which is a significant, offer previously unused potential for optical effects. These Effects are mainly due to the nature of the scattering body, the are essentially transparent and not mirrored, irregular and non-flat boundary surfaces have caused. Advantageously, the scattering bodies have lenticular or spherical inclusions which focus or scatter the light reflections in the auditorium.
  • Around to amplify the effects is it possible that diffuser artificially to color, allowing them to absorb light in a certain frequency range of the incident light. It is particularly impressive the scattering bodies to arrange and illuminate the reflections directly in to radiate the auditorium. Through a pile of illuminated scattering body according to the invention can the impression of incandescent lights to be awakened. It is particularly advantageous, the light intensity of the light source time-dependent to change. To be natural It is also possible to produce either effective effects or effects to excite the light source to a mechanical vibration. Vorteilhafterveise the frequency of the oscillation ranges between 10 and 10,000 Hz.
  • Advantageous is further that the easily manageable diffuser in any arrangement in the stage decoration integrated or arranged as a decoration on the theater stage. The lighting can be caused by light sources in the immediate vicinity of the scattering body or be done by 1 to 10 meters away light sources. For the lighting through Remote light sources are particularly focused Spotlights, in particular spotlights.
  • As a material for the scattering bodies according to the invention melted water glass, an alkali metal silicate is used, which in relation to air has a refractive index of 1.45 to 1.55 has. Water glass has mechanical and optical properties that are comparable to conventional glass. Melt-technologically produced water glass is characterized for the present application, especially by the inclusion of gas bubbles, which inevitably get into the material during manufacture. These "natural" inclusions further enhance the aesthetic effect of the lighting.
  • The irregular uneven boundary surfaces the scattering body are made by breaking individual fragments from a piece of solid material in particular on cooling the melt produced. To some degree of roughening of the surfaces too can reach, outside pressure on a pile of fragments exercised so that the individual fragments scratch each other. diffuser made of water glass can be roughened in a simple way mechanically.
  • The Size of one single scattering body can between 1 and 30 cm. Because the proposed materials heat-resistant are from them, even with very powerful light radiation no fire hazard.
  • In a special embodiment The lighting becomes a conglomeration relatively small-sized scattering body on arranged a light source, which advantageously in the ground the stage is admitted. Due to the indirect lighting the pile seems embers glowing and awakens particularly mysterious associations at the viewer.
  • The Refinement of the invention is the expert without further action possible. So is water glass after a usual industrial melting process produced (see Römpp-Chemie-Lexikon, 9th edition, 1992, p. 5003).
  • One embodiment the stage lighting according to the invention is shown in the drawing and will be described in more detail below.
  • The figure shows a schematic representation of an accumulation 1 individual scattering body 2 , which is arranged on a stage, not shown. The accumulation 1 is by a light source in the form of a focusing radiator 3 with a ray of light 4 illuminated. The incident light 4 becomes by scattering body 2 reflected. The reflections 5 get to the eye 6 the viewer, who is in the darkened auditorium.
