Abstract

The device comprises one or more light diffusers which form an ensemble, illuminated by one or more light sources. One diffuser (2) is transparent, is not mirrored irregularly and does not have even limiting surfaces. The diffusers are so arranged that the diffused light (5) is diffused in a darkened auditorium. The dimensions of a diffuser is between 1 and 30 cm. The light sources (3) are focussed radiators. The surfaces of the diffusers can be mechanically or partly roughened. The diffusers can be broken pieces of solid material, and have a refraction index of 1.45 to 1.55 against air. They may also be coloured.

Description

The invention relates to a method and an apparatus for Creation of aesthetic lighting effects in artistic Installations or in an auditorium.

It is known to use game stages in particular from theaters to illuminate a variety of headlights depending on the Set design can be combined into groups. Through the Combination, through fluctuations in intensity or through Movements of the headlights can be a variety of achieve aesthetic effects. It is also known lighting effects, for example flames of a Simulate fire by irregular illumination of To produce objects or by backlighting. Furthermore, aesthetic lighting effects are also indirectly through the refraction and reflection of light on planes or regular curved surfaces. Except for such mirrors in practice, even small bodies whose Reflect boundary surfaces (scattered bodies), in particular artificial snow and the like.

A disadvantage of the known methods is that they are very are complex and therefore expensive. In addition, it has so far been successful not the effect of naturally irregularly glistening Light such as glowing white heat is broadcast in astounding for the viewer To create authenticity.  

The object of the present invention is therefore a Provide procedures that the viewer artistic installations give the impression of a brilliant radiant object of great naturalness and achieved particularly aesthetic lighting effects. At the same time it is an object of the invention a device for To carry out the procedure.

This problem is solved by the method in which Diffusers or several combined into an ensemble Diffuser illuminated by one or more light sources be a diffuser essentially transparent is essentially irregular and not mirrored has non-planar boundary surfaces and the or the diffusers the stray light into a darkened Scatter auditorium.

The task is also performed by a device for Implementation of the procedure solved.

Advantageous embodiments of the invention The method and the device according to the invention are in the Subclaims listed.

According to a particularly suitable embodiment of the invention the aesthetic lighting effects become the eye of the beholder fed, who is in a darkened room. The Invention is therefore particularly for the generation of Suitable for stage sets in theaters or opera houses.

Particularly advantageous in the inventive Stage lighting is that it can be done with simple means amazing effects achieved. In particular, the Diffusers made of readily available and cheap materials manufacture and process by known methods. For Illumination of the diffusers can a. also those in the Stage equipment existing headlights or conventional Be incandescent.  

By the stage lighting according to the invention in particular through the lumpy and broken glass-like scattering bodies, which are used individually or combined into an ensemble new light reflections can be generated, which a considerable, previously unused potential of optical Offer effects. These effects are mainly due to the Condition of the scattering body, essentially are transparent and irregular and not mirrored not have flat boundary surfaces. The scattering bodies advantageously have lenses or spherical inclusions, which the light reflections in the Focus or scatter auditorium.

To intensify the effects, it is possible to use the diffuser to be artificially colored so that they absorb light a certain frequency range of the irradiated Have light. It is particularly impressive that Arrange and illuminate the diffuser so that the Reflections shine directly into the auditorium. Through a Pile of illuminated scattering bodies according to the invention can Impression of incandescent lights. It is the light intensity of the light source is particularly advantageous to change depending on the time. To have natural-looking effects it is also possible to generate either the diffuser or to excite the light source to mechanical vibration. The frequency of the vibration is advantageously in the Range between 10 and 10,000 Hz.

Another advantage is that the easy to handle Diffusers in any arrangement in the stage decoration integrated or as decoration on the theater stage can be arranged. The lighting can go through Light sources in the immediate vicinity of the diffuser or through Light sources 1 to 10 meters away. For the Illumination by distant light sources are suitable in spotlights in particular focused Spotlight.  

The materials for the scattering bodies are particularly suitable those with a refractive index of air 1.45 to 1.55. As material for the scattering bodies according to the invention, glass, glass-like plastic or in particular "water glass" produced by melting Alkali silicate used. Water glass has mechanical and optical properties with conventional glass are comparable. Melted water glass stands out, however, for the present application by the inclusion of gas bubbles from the Manufacturing inevitably get into the material. By these "natural" inclusions become the aesthetic effect the lighting further strengthened.

The irregular and uneven boundary surfaces of the Diffusers are broken out by breaking individual fragments a piece of solid material especially when cooling the Melt generated. To a certain degree of roughening the Reaching surfaces can put external pressure on a bunch be exercised by fragments so that the individual Scratch each other fragments. Diffuser made of glass or water glass can be easily mechanically roughen.

The size of a single diffuser can be between 1 and 30 cm be. Because the proposed materials are heat resistant are from them even with very powerful Exposure to light does not pose a fire hazard.

In a special embodiment of the lighting, a Accumulation of relatively small pieces of scattering material on one Light source arranged, which is advantageously in the ground is embedded in the stage. Through indirect lighting the bunch seems to glow like a glow and particularly awakens mysterious associations with the viewer.

The reworking of the invention is without the expert further action possible. So water glass becomes after one  usual industrial melting process (see Römpp-Chemie-Lexikon, 9th edition, 1992, p. 5003).

An embodiment of the invention Stage lighting is shown in the drawing and will described in more detail below.

The figure shows a schematic representation of a cluster 1 of individual scattering bodies 2 , which is arranged on a stage, not shown. The cluster 1 is illuminated by a light source 4 in the form of a focused radiator 3 . The irradiated light 4 is reflected by the surfaces and inner boundary surfaces of the diffuser 2 . The reflections 5 reach the eye 6 of the viewer who is in the darkened auditorium.
