Definitions

  • the invention relates to a device for generating visual effects according to the preamble of claim 1.
  • Such devices are preferably used for decorative purposes, for example in department stores, car showrooms, exhibitions or offices, but can also be used in advertising and in color therapy.
  • the constant change in structure, including color and light variations, draws the attention of an observer to such devices.
  • an effect element for liquids with a closed air circuit is known.
  • This effect element consists of a transparent material and is filled with a liquid.
  • An exhaust pipe is installed above the liquid level, which is connected to an outflow via a pump. With the help of the pump, the air is pushed through the air outlet, so that finely distributed air bubbles rise up through the liquid.
  • WO-0068612 describes a lamp in which fluids can be contained as gas and / or liquid of any color which are moved by a micropump.
  • the entire device is quite voluminous in terms of format.
  • the novelty represents the connection between emitted light and the liquid effect, the effect of which is similar to the reflection of light by a moving liquid.
  • a device is known from US-A-4057921, in which at least two immiscible liquid phases between walls which are parallel to one another and are arranged at a short distance from one another are arranged. The density of the phases is different, so that certain flow patterns occur when this device is turned or turned.
  • FR-A1-2 651 598 for example, air is introduced into a liquid from above by means of a pump, this device having an illumination device on its rear side.
  • the device for producing visual effects known from US-A-4034493 has two parallel walls which are arranged at a short distance from one another and which are partially connected to one another by means of chicane. The free space between the walls is filled with liquids of different densities. Flow patterns result when this known device is turned or turned.
  • a device is known from US-A-4 085 533.
  • the liquid consists of at least two immiscible liquids of different densities, so that in the idle state the liquid phases are arranged one above the other with a largely horizontal phase separation line.
  • the device can have a pump which circulates the liquid in phases, for example. It is also possible to connect several of these devices via pipes.
  • the liquid phases used in this device can contain a colorant, such as pigments.
  • the device is usually filled with three different liquid phases. Such a device is complicated due to the three different liquid phases and the pipelines opening into these phases and therefore has a high price.
  • the invention has for its object to provide a device of the type mentioned, which is simpler and yet works effectively.
  • the liquid-receiving space formed between the walls can have two chambers in a simple manner, which, for example, conveys air from one chamber via at least one through-opening to the other chamber filled with liquid, which creates interesting flow and color effects ,
  • the walls are advantageously transparent, parallel to one another
  • Plexiglass panes with a mutual distance of about 5 mm Such walls are light in weight and, unlike glass, are relatively insensitive to breakage. Due to the small mutual distance between the walls, the volume of the liquid used in the device according to the invention is greatly reduced, so that only a small amount of liquid has to be circulated by the pump to produce visual effects.
  • the pump can therefore be dimensioned small, so that the power consumption of such a pump is also low.
  • the device according to the invention therefore causes only low operating costs and can therefore be operated very economically.
  • the liquid is water, preferably fully demineralized water
  • the colorant is at least one pigment, the colorant preferably having non-toxic white, colored and / or gloss pigments.
  • Such water can remain in the device for a long time since it is chemically very stable and therefore does not decompose even after prolonged operation. Cleaning the inside of the wall is largely unnecessary. Algae hardly form in the water. With the help of the pigments mentioned, special coloring and flow effects can be achieved.
  • the two chambers are separated from one another by means of a perforated perforated plate having numerous through openings or a porous sintered plate.
  • the desired effects can thus be further intensified, since these occur at each individual passage opening.
  • elements are installed as flow resistances above the sintered layer and a clock generator is connected in front of the pump, which further increase the conspicuousness of the device.
  • the rear wall is illuminated by means of a lighting device, the lighting device preferably being designed in such a way that the attractiveness can be further increased by exchangeable and / or rotating color foils.
  • Figure 1 is a schematic, partial front view, partially in section, of a device for generating visual effects.
  • Fig. 2 is a schematic section along the line 11-11 in Fig. 1;
  • Figure 3 is a schematic front view, partly in section, with the surrounding frame.
  • Fig. 4 shows a plan view of a movable lighting device
  • Fig. 5 is a plan view of a lighting device with moving color foils.
