Description

 The proposed device relates to lighting and lighting technology.

 There are many devices with illumination properties, containing transparent vessels with illumination and optical additives suspended in them that serve to scatter light. The closest analogue of the invention can be considered the device described in autosvid. USSR N 1142697, 1985.

 The essence of the invention lies in the fact that optical additives in a vessel in suspension and in a liquid or gas under the action of an electric and / or magnetic field are aggregated on the inner surface of the vessel walls in the form of various graphic symbols or figures.

 The optical additives used in the device are particles that can have different physicochemical characteristics. Optical additives can be made of a homogeneous metal or dielectric material, and can be a composite material, for example, a metallized polymer film.

 It is possible to use electret particles of electrets and piezoelectric elements as optical additives, which helps to accelerate the process of mixing particles under the influence of an electric or magnetic field.

 The choice of liquid or gas to fill the vessel is determined by the type and fluctuation of the applied fields, the properties of the optical particles, as well as the shape of the vessel.

 Systems of capacitors, solenoids, permanent and variable magnets, etc., can be used as sources of magnetic and / or electric fields that allow creating different modes at different points in the space inside the vessel.

 In particular, a high voltage power source or an electrostatic generator can be selected as the source of the electric field.

 In FIG. 1-5 presents various embodiments of the proposed device.

 In the vessel 1, made of a transparent material, there is a liquid 2 with optical additives suspended in it 3. The device 4 creates a charge on the plates of the capacitor 5, thereby forming an electric field (Fig. 1). Under the influence of the electric field and due to the electrification in the mixture of additives that differ in their physical properties, a redistribution of charges will occur, they will be electrified and attracted to the plates of the capacitor. The plates can be made in the form of various graphic figures, for example 6, which are made visually different and stand out on the vessel wall when aggregation of additives near them is similar to the process of developing a latent image in electrophotography. Capacitor plates can be made in the form of containers with a transparent electrolyte inside the walls of the vessel or from a conductive material with a lower optical density than optically active additives. The circulation of additives inside the vessel is carried out either by forced circulation (pump 7), or by periodically exposing the suspended additives to a magnetic and / or electric field.

 For example, when magnetically sensitive additives are exposed to a changing magnetic field, the required characteristics of their circulation inside the vessel can be achieved, in particular by means of a rotating permanent magnet 8 located under the vessel.

 The device provides a heat source 9, which will contribute to the occurrence of convection flows in the liquid.

Illumination device can function as in reflected light
from an external source, and have your own light source 10.

 The capacitor plate can be made in the form of an electronic indication of the clock 11 (figure 2). By synchronizing the time the potential is supplied to the various segments 12 with the clock mechanism 13, a visual indication of the time can be made.

 It is possible, instead of the source of the field in the form of a capacitor, to make it in the form of a plate located on one side of the vessel wall, and charge the other polarity to the earth or to another body, the size and remoteness of which will not affect the additives. To improve the visual characteristics of the device, it is possible to make one of the capacitor plates completely from an optically homogeneous material 14 in the form of a double wall with an electrolyte inside or coated with a conductive material with a low optical density, and to regulate the shape of the field 15 (the resulting symbols) by changing the shape of the plates 16 on the back darkened wall 17 (figure 3).

 As a special case of the implementation of the device, one can note the option when there is a device for the electrification of the walls of the vessel and additives by mechanical transfer of charges (figures 4 and 5). The device 18, when moving downward in the vessel, in contact with the additives and the walls of the vessel, electrolyzes them relative to each other, and the additives are attracted to the walls of the vessel, forming symbols. The place and form of the concentration of charges on the electrified wall of the vessel can be set using materials with different dielectric and electrical conductive properties as the material of the wall of the vessel.
