Description

 The invention relates to the field of volumetric display of information, in particular by means of light elements controlled by an electronic processor, and can be used in advertising, during cultural events, in training, as well as to create new types of lamps, games and playback of volumetric images when they are transmission.

 Systems are known in which a pseudo-volumetric image is created due to a stereoscopic effect on the screen of a cathode ray tube (see AS USSR 590726, G 06 F 3/14, 1978; UK patent 1294162, CL H4T, 1969; US patent 3626404 Cl. 340-324, 1971).

 The disadvantage of these systems is that the image is not three-dimensional, but to obtain the effect of volume, the observer needs to be at a certain point in space and / or have stereoscopic glasses. This is not acceptable for the mass media.

 Also known are devices for three-dimensional display of information, containing light elements uniformly fixed throughout the volume of the future image, which are turned on in accordance with the program of the master unit. Of these, the closest in technical essence is a device for volumetric indication (see AS USSR 364125, H 04 N 5/66, 1973).

 This device contains light elements in the form of gas-discharge tubes placed in space and fixed on the base - individual points of which at the intersection of the electrodes are highlighted according to the program embedded in the master unit. The known device allows you to build a real three-dimensional image, however, it also has drawbacks.

 Since the light elements are static, to obtain a high-quality three-dimensional image, you must place the largest number of light elements in the volume. At the same time, tubes that do not glow at the moment obscure the image.

 In addition, a large number of elements complicates the master unit, communication lines, reduces the reliability of the device.

 The problem solved by the claimed invention is to build a real three-dimensional image, transparent in any angle, not having in the volume of shading elements, quite bright and multicolor.

 This problem is solved by the fact that in the known device for a three-dimensional image containing light elements placed in space, a driver unit associated with them installed on the base, light elements are placed on the consoles of a given shape, and the latter are installed on the base with the possibility of periodic ordered movement.

 In this case, the consoles can be installed with the possibility of rotation together with the master unit relative to one center, and the radii of rotation of the consoles are different.

 Consoles can be made with the possibility of changing and fixing the form.

 Light elements on different consoles can have a different color.

 The driver unit may be associated with an external device for storing and processing image information.

 Placing light elements on movable consoles makes it possible to move them in space at a certain speed, at which, for the human eye, the trajectories of individual light elements merge into a continuous line and repeat the shape specified by the consoles. To maintain the image, the consoles are mounted on the base with the possibility of periodic (repeating) and ordered movement.

 The possibility of rotation of the consoles gives the most technically feasible version of the periodic ordered movement, and the rotation of the consoles together with the master unit simplifies the implementation of the connections between them.

 The location of the consoles at different radii of rotation allows you to use overlay images.

 The supply of different consoles with light elements of different colors leads to color mixing and the appearance, depending on the given program, of multi-color complex shades of a three-dimensional image.

 An external device, such as a PC, improves quality, improves responsiveness in processing image information.

 The drawing shows an embodiment of the proposed device with rotational motion.

 A specific example of implementation provides a base 1 with a mounted electric motor, on the axis 2 of which are mounted a console 3 in the form of an arc of a circle and a console 4 having a vertical section, LEDs 5 mounted on the consoles 3, 4, the setting unit 6, the fixed contact 7 and the brush 8, power supply 9, magnet 10 and reed switch 11. Consoles 3, 4 have different radii of rotation.

 The device operates as follows. When applying voltage from a power source 9, the axis of the electric motor 2 spins up to 25-30 rpm. At the same time, through the contact 7 and the brush 8, the master unit 6 is energized, which, rotating on the axis 2 together with the consoles 3, 4, transmits the programmed signals to the LEDs 5 on the consoles 3, 4 via communication lines.

 Each of the LEDs 5 turns on and begins to glow for a given period of time at a given point in space, and then turns off. A segment of the luminous trajectory of each LED 5 creates a three-dimensional image element. Having made one revolution, the driving unit 6 repeats the signals, thus maintaining the ordered periodicity of the flashes and attenuations of the LEDs 5. A pair of “magnet 10 - reed switch 11” provides a synchronization of the signal supply by revolutions.

 The peculiarities of human visual perception at a rotation speed of about 25 rpm are such that the sections of the luminous path of the LEDs 5 merge for the eye into a line of even bright light, and not the luminous parts (dimmed LEDs 5, console 3, 4) become invisible. As a result, the observer sees a bright, really voluminous figure. In this example, the console 3 in the form of an arc of a circle creates a globe with the contours of the continents, and the vertical section of the console 4 describes a tape around the globe with an advertising label.

 Moreover, for the observer, the ball hangs in space and is translucent, and the inscription can be either fixed or in the form of a running line. The effect of the obtained image cannot be compared in terms of impression power with other types of volumetric images and, most importantly, is observed at any angle and at any distance without additional technical means (for example, without stereo glasses).

 The same effect can be obtained with a plane-parallel reciprocating movement of the consoles with a high frequency, however, the mechanism that performs this movement is more complicated than for the rotational one.

 Consoles of various shapes create different bodies of revolution and, accordingly, different three-dimensional luminous images.

 If the console is made with the possibility of changing and fixing the form, for example, from interconnected fixed hinges, then it will be able to create many images.

 By installing LEDs of different colors on different consoles, you can get a multi-color three-dimensional image by applying different shades to each other.

 As an option, which significantly improves image quality and allows you to obtain very complex, including moving color images, an external device for storing and processing information about the image can be used in conjunction with the master unit. For example, a CD player, TV tuner, camcorder, VCR, PC. These devices, having great capabilities for storing and processing information, make it possible to simplify the master unit to the functions of receiving information and controlling LEDs. The communication between the external device and the master unit may be wired or wireless via infrared or radio communication.

 The technical means used in the manufacture of the described embodiment of the device are widespread and linked according to well-known design laws. For example, the microprocessor is used in the driver unit, the other elements do not need to be explained. The principles used in the inventive device are also widely known: it is a mechanical scan of the image, the programmed control of light indication devices and the strobe effect (for the latter see, for example, AS 55929, G 09 F 13/34, 95188, G 09 F 19/02).

 However, the combination of known elements gave an unexpected super-total effect: a real three-dimensional image of almost any information in color, which was not visually associated with any medium.
