Description

 Device for presenting advertising information

The utility model relates to advertising and can be used by visual reproduction of remotely variable information as a means for multimedia visual support for presentations and various kinds of mass events held, for example, in the open air, as well as during advertising campaigns, including in places sales, exhibitions and fairs.

State of the art

A mobile advertising device containing a van having a side hinged lid covering the side window, loudspeakers installed therein and electronic means containing various bases of audio and video materials is known, and the van is additionally equipped with a light screen, a video projector and a mirror mounted on the side window. moreover, the light-transparent screen, the video projector and the mirror have a common optical system (see RF certificate for utility model N ° 13985, IPC G 09F 21/04, published on 06/20/2000).

However, the known device has a limited area of the screen field, determined by the area of the side window in the van, which reduces the number of people who can simultaneously observe advertising information on the screen. In addition, in the well-known advertising and information mobile device, the screen is located approximately at the level of human growth, which also leads to a decrease in the number of people who can simultaneously observe information on the screen, since with a sufficient concentration of observers, for example, at exhibitions or presentations, only the first row will be able to observe information, closing it from standing behind people.

Also known is a mobile module with an information display comprising a vehicle equipped with a device supporting a screen onto which an image is transmitted, for example, from a video recorder located in a vehicle. In this case, the supporting device is made movable with respect to the car: in the initial position, the supporting device is located behind the rear of the car, and in the working position - in front of it side (see French patent for the invention Ns 2705158, IPC G 09F

21/04, G 09F 7/18, publ. November 18, 1994).

The screen of the known device is also located no higher than the roof of the car, i.e. at the level of human growth, while the screen area is limited by the dimensions of the vehicle (i.e. the height of the vehicle), to which a device is attached that supports the screen in height and width, for example, by the width of its rear. These factors reduce the number of people who can simultaneously observe information on the screen, due to the limited screen field and access to it.

A vehicle with an advertising information carrier is known, which is a van, inside of which at least one cinematic device is located, which, through a mirror, projects a video image onto at least one translucent screen mounted on the van body and visible from the outside vehicle. The device also includes one or more outward speakers and a power source. Additionally, the device is equipped with a group of illuminated panels installed around the vehicle, and illuminating the bulletin board installed on the roof of the car. Thus, the vehicle provides the mobility of the presentation of advertising information on public roads by means of video-audio advertising information (see WIPO patent for invention N ° 9316460, IPC G 09F 19/18, G 09F 21/04, publ. 08/19/1993 g.).

However, the screen of the known device is also located no higher than the roof of the car, i.e. at the level of human growth. This reduces the number of people who can simultaneously observe information on the screen due to the limited screen area and access to it, since the screen area is limited by the dimensions of the vehicle, for example, the side or back sides, i.e. the location of the translucent screen.

Also known is a mobile advertising and information device containing a van having a light screen located in a side window, electronic means installed in the van, containing various bases of audio and video materials, a video projector and a first mirror having a common optical system with a light screen, and a second mirror having a common optical system with a second mirror having a common optical system with a horizontally mounted video projector, a first mirror and a light-shielding screen, a frame on which the van is rigidly mounted, having a mechanism for connecting it to the chassis of a car or car trailer and four telescopic supports equipped with a pneumatic drive (see RF certificate for utility model JYo 25362, IPC G 09F 21/04, published on September 29, 2002).

A disadvantage of the known device is also the limited visibility of the light-transparent screen, since it is at the vehicle level, i.e. at the level of human growth. This makes it difficult to obtain visual information from him from people who are at a considerable distance from the screen, or when there is a large crowd of people, for example, at exhibitions or presentations, from people who are not in the front row of viewers.

A mobile advertising device is known, comprising a van equipped with a window on which a light screen, a video projector and a mirror are mounted, the light screen, a video projector and a mirror having a common optical system, while the van is equipped with a second, third or more windows on which are installed light-transparent screens, the video projector and light-transparent screens having a common optical system with the ability to switch (see RF certificate for utility model JN ° 20802, IPC G 09F 2 1/04, published on November 27, 2001).

A disadvantage of the known device is also the limited visual access to the source of the dissemination of information, namely the screen. The screen area in this case is limited by the window size, which does not allow the use of screens of a larger area than the window area. At the same time, the screen is located at a small height, for example, not exceeding human growth, which also reduces the number of people who can simultaneously observe information on the screen, due to the limited access to it with a large crowd of people.

The closest technical solution is the well-known means for multimedia presentation of advertising products, containing a car, inside which there is a projector and a screen, while the projector is located in the rear of the car and is oriented towards the rear door of the car. The projector is mounted on a solid support to which aluminum is attached. the frame on which the projection screen is located located in the rear aperture of the car (see German patent for invention N ° 19938330, IPC G 09F 21/04, G 09F 19/18, G 09F 13/02, B 6OR 13/00, B 6OR 11/02, publ. 02.15.2001).

However, with the known device, the screen area is limited by the size of the rear door and, thus, does not allow the use of screens of a larger area. At the same time, the screen is located at a low height, which also reduces the number of people who can simultaneously observe information on the screen, due to the limited size of the screen field and access to it.

Utility Model Disclosure

The task to which the present utility model is directed is to create a device for presenting advertising information with a design that provides an increase in the number of people who can simultaneously observe advertising information.

The technical result achieved in solving the problem lies in the absence of dependence of the screen field area and the possibility of its visual observation from the dimensions of the vehicle, while maintaining reliable optical communication between the projector and the screen and high-quality image on the screen, as well as high mobility of the device and short time required to bring it into working condition.

The problem is solved in that the device for presenting advertising information containing a projector and a screen on which a light signal is supplied from the projector, a vehicle, while the projector is located inside the vehicle, according to a utility model, equipped with at least one additional projector, located inside the vehicle, the screen is located outside the vehicle and is equipped with a supporting device, while light signals are transmitted directly from each project ra on the screen through the opening in the vehicle body, are aligned on the screen, the total light output from all the projections is at least 500-ANSI lumens.

It is advisable that the supporting device of the screen was either attached to the vehicle body, or mounted on the supporting surface of the vehicle, or made in the form of a wall mount. Each projector can also be equipped with a support device attached to the vehicle body.

In this case, the screen can be made light-illuminating.

In the present description of the utility model, the following terminology is used:

- luminous flux - the power of radiant energy, estimated by the visual sensation produced by it (in SI it is measured in lumens, lm) (see, for example, the Soviet Encyclopedic Dictionary / Scientific and Editorial Council: A.M. Prokhorov (previous) .- M .: Soviet Encyclopedia, 1981, p. 1189). Those. the luminous flux is one of the luminous quantities that estimates the energy value - the radiation flux, i.e. the power of optical radiation, by the light sensation caused by it [more precisely, by its effect on a selective light detector, the spectral sensitivity of which is determined by the function of the relative spectral light efficiency of radiation V (1); 1 - wavelength of light in vacuum]. Luminous flux is the most important characteristic of a projector. For example, the luminous flux of a professional film projection apparatus is in the range from 350 to 50,000 lumens, amateur - at least 50 lumens. The largest luminous flux is generated by an electric carbon arc lamp (50,000 lumens), the smaller one is produced by a gas discharge (xenon) lamp (15,000 lumens) and even smaller is produced by an incandescent lamp (90 lumens). Therefore, projectors with arc projectors are installed for large cinemas with large area screens coal or xenon lamps; in cinemas of low capacity, as well as in cinema installations for educational, amateur, etc. For this purpose, projectors with an incandescent lamp are used (see, for example, the Great Soviet Encyclopedia, the article “Film projection apparatus, [access mode: http://encycl.yandex.ru/, 03/10/2005]]. Moreover, at present, in the accompanying and technical documentation, the luminous flux of projection devices is indicated in the so-called ANSI lumens, which characterizes the average value of the luminous flux measured in lumens on a control screen with a diagonal of 40 inches with a minimum focal length of the projector’s zoom lens. Measurements are taken at 9 points on the screen and then averaged. ANSI Lumens (ANSI Lumens) standard for measuring luminous flux, used to compare projectors. The method of measuring luminous flux in ANSI lumens was approved in 1992 by the American National Institute of Standards (ANSI - National Institute of Standards (ANSI - Аmerisap Natiapl Standart Istitutе) [access mode: http://bolivar.spb.ru/; March 14, 2005];

- a light-transparent screen is a screen that can be viewed from the reverse side of the projector (see, for example, patent for an invention of the Russian Federation N ° 2209457, IPC G 03B 21/00, published on July 27, 2003).

The technical result in solving the problem is achieved due to the following.

It is advisable to place the projectors inside the vehicle, since otherwise (i.e. when placing the projectors outside the vehicle), additional protective devices are necessary to protect the projector from negative environmental influences: dirt, dust, moisture, heat. In this case, the vehicle acts as a natural protective element. The absence of such an element will lead to a deterioration in reliable optical communication between the projector and the screen and the impossibility of achieving high quality image on the screen, since improper operation of the projector in an emergency mode will be possible and it will not be possible to transmit a signal corresponding to the projector's operating characteristics. However, the presence of any additional protective device, in addition to the car, will increase the time required to bring the device into working condition, which will negatively affect the mobility of the device.

When placing the screen outside the vehicle, the dependence of the screen area on the dimensions of the vehicle, in particular, the location of the screen, namely the window or opening in the body, as was done with the known analogues, disappears, and it becomes possible to increase the screen area and the height of the screen, why the screen is additionally equipped with a supporting device, which can either be attached to the car body or mounted on a supporting surface, for example, attached to the vehicle body with means, and can also be made in the form of mounting the screen on any supporting structure, for example, a wall. Such a placement of the screen will, with an increase in the area of the screen and the height of its placement, in turn, increase the number of people simultaneously observing the information on the screen. However, when placing the screen outside the vehicle, the optical connection between the screen and the projector may be degraded. This is because in this case it will be necessary for the signal from the projector to pass through openings in the vehicle body, for example, through an opening in the rear of the vehicle, or through an opening in the front of the vehicle, for example, the location of the front windshield, which when insufficient optical radiation power and orientation of the projector relative to the screen at a certain angle will make the image on the screen fuzzy and weakly distinguishable.

The experimental data indicate the following.

The projector was installed inside the vehicle, namely the Oka passenger car. The screen was placed outside the vehicle on a support device attached to the vehicle body, or δyl was mounted directly on the support surface of the vehicle, for example, ground. The light signal was transmitted through an opening in the vehicle body from several projectors inside the vehicle. During the experiment, projectors with different nominal luminous flux were used in turn, and the signals from all the projectors were combined on the screen.

Observation of the image on the screen was carried out visually by a group of people with normal vision without special means of observation, for example, binoculars. The light signal was transmitted in the dark and in the daytime.

The experimental results are shown in the table.

Table

The experiment was repeated at different positions of the screen relative to the vehicle. The maximum distance of the screen from the projector inside the vehicle was 10 m, the minimum 2 m. At the same time, increasing the distance (up to 10 m) revealed a significant deterioration in the quality of the image from the projector with a light flux, for example, 400 ANSI-lm. The contours of graphic objects became blurry, the color scheme faded. When using projectors with a total luminous flux of 500 ANSI-lm high: the image quality when moving the screen to a distance of 10 m remained unchanged.

Thus, it can be seen from the data presented in the table that the following circumstances are necessary conditions for a high-quality image transmission to the screen: the presence of a total luminous flux of at least 500 SHSI-lm, as well as the combination of signals from all projectors on the screen (otherwise, simply it will not be possible to achieve a clear picture on the screen).

However, it should also be noted that the number of projectors is not regulated, since combining signals using modern technologies can be achieved automatically by setting up projectors. At the same time, destructive results in transmitting high-quality images were achieved chunks during the experiment when transmitting the same image from both two and three projectors.

To further increase the number of people who can simultaneously observe information on the screen of the proposed device, the screen is proposed to be made light-illuminated, i.e. information on it can be observed from the side opposite to the placement of the vehicle relative to the screen.

The proposed implementation of the device for the distribution of advertising information will allow the vehicle to move either with an already installed screen and projectors, or will allow them to be mounted quickly before the start of a presentation or exhibition, which preserves the high mobility of the device and the short time required to bring the device into working condition. In addition, the presence of a support device for each projector attached to the car body additionally reduces the time for putting the device into working condition, and also allows the vehicle to move to the place of presentation almost ready to display visual information.

The best options for implementing a utility model

A device for presenting advertising information comprises a projector 1, a screen 2, on which a light signal is received from the projector 1, and a vehicle 3.

The projector 1 is located inside the vehicle 3, and the screen 2 is located outside the vehicle 3.

The device is equipped with at least one additional projector 4, also located inside the vehicle 3. A light signal carrying identical information is transmitted directly from projectors 1 and 4 through an opening in the vehicle body 3, matching on screen 2, and the total luminous flux of projectors 1 and 4 is at least 500 ANSI-lm.

The screen 2 is equipped with a supporting device 5, which is attached to the body of the vehicle 3, or mounted on the supporting surface of the vehicle 3, or made in the form of a wall mount (not shown). Screen 2 can be made light-illuminating.

Projectors 1 and 4 can also be equipped with support devices 6 and 7, attached to the body of the vehicle 3.

As projectors 1 and 4, a projector of the Sapuo XT 16 type (Japan) can be used. As screen 2, a screen of the type Rover Computers Rover-Sсrеep (Russia) can be used.

A device for presenting advertising information is used as follows.

Vehicle 3 moves to the venue, for example, during an exhibition or presentation. During transportation, projectors 1 and 4, screen 2, supporting structures 5, 6 and 7, respectively, of screen 2 and projectors 1 and 4, can be located inside the vehicle body 3. After placing the vehicle 3 at the place of the advertising campaign, assemble and installation of supporting structures, for example, attaching them to the body of the vehicle 3, or installing on a supporting surface outside the vehicle 3 (supporting structure 5 of the screen 2). Projectors 1 and 4 can be connected via a voltage converter to the battery of the vehicle 3, or equipped with an autonomous power source. From projectors 1 and 4, information in the form of light signals through an opening in the back of a vehicle 3, which can be closed by a protective light-transparent surface, is fed to a screen 2, which can be positioned at a sufficiently high height, ensuring its simultaneous observation by a sufficiently large number of people. The signals from projectors 1 and 4, the total luminous flux of which is at least 500 ANSI-lm, are combined on the screen, forming a clear and clear high-quality color image. In this case, the display of video information may be accompanied by the transmission of audio information, for example, through sound transmission means, namely, speakers located, for example, on a vehicle 3.

After the information is shown at the end of the event, the projectors 1 and 4, the screen 2, the supporting structures 5, 6 and 7 are dismantled if necessary and the vehicle 3 can quickly move to another place of information display, providing mobility of the device.

Thus, the proposed device for the presentation of advertising information can be used as a means for multimedia visual support for presentations and various kinds of mass events, for example, advertising campaigns conducted, for example, in the open air. At the same time, the device has high mobility, requires a short time to bring it into working condition, and provides simultaneous visual access to advertising information for a wide range of observers, providing reliable optical communication between projectors and the screen and high quality image on the screen.
