Description

The claimed utility model relates to lighting information devices, luminaires for various purposes and can be used, in particular, as a street sign, vehicle registration plate, marker, advertising information device, or a pointer in an alarm system, with network or autonomous power supply, in stationary or mobile execution.

Known LED information panel, which contains a housing, a board with LEDs located on the surface of the plate, a diffuser made of transparent plastic with information symbols. (See, for example, RF patent No. 2143139 "Indication device", IPC G 09 F 9/302, publ. 12/20/99. In B.I. No. 35).

A disadvantage of the known technical solution is that the known LED panel can find limited application, for example, in dashboards. In addition, it is laborious to manufacture, has a large weight and is equipped with a special, complex diffuser.

Closer in technical essence to this utility model and adopted for the prototype, is the light panel described in utility model of the Russian Federation No. 41181 "Advertising lighting device", IPC G09F 9/00 publ. 10/10/2004 in B.I. No. 28.

Known light panel contains a diffuser, information symbols made in the form of a stencil, a housing with a base and light sources located inside the housing.

Known light panel has a relatively low weight.

A disadvantage of the known light panel is that incandescent lamps are used as light sources, and the light flux emitted from the known panel is not uniformly distributed over the diffuser. Panel service life is short; what is determined by the applied light sources. Changing the brightness and color of the glow in it is almost impossible. Therefore, such a panel has limited use as illuminated advertising information.

The technical problem solved by the proposed utility model is to expand the range of application, increase the service life, with a stable and evenly distributed light flux on the surface of the diffuser. In addition, the problem of changing the brightness of the glow of information symbols is solved, depending on the ambient light and, if necessary, changing the color of the glow.

The technical result is achieved due to the fact that the universal LED information panel containing the diffuser, information symbols made in the form of a stencil, the housing with the base, the light sources located inside the housing and the power supply and control unit, according to the utility model, to one edge of the base, under angle to the base and diffuser, a shelf is attached, the diffuser is located between the outer edge of the shelf and the other edge of the base, light sources are placed on

the board, the board is attached to the inner side of the shelf, the light sources are LEDs, and the power and control unit is electrically connected to an ambient light sensor mounted on the outer surface of the panel housing, and the inner surface of the base has a reflective coating.

In the embodiment of the technical solution, the shelf is located at right angles to the base, and the LEDs are mounted on the shelf so that the central axis of their light fluxes run parallel to the plane of the base.

In a variant of the technical solution, the shelf is located at right angles to the diffuser, and the LEDs are mounted on the shelf so that the central axis of their light fluxes run parallel to the plane of the diffuser.

In a variant of the technical solution, the shelf is located at an acute angle to the base and the diffuser, and the LEDs are mounted on the shelf so that the central axis of their light fluxes pass between the plane of the base and the plane of the diffuser.

In a variant of the technical solution, the inner surface of the base is corrugated.

In a variant of the technical solution, information symbols are located on the inner surface of the diffuser.

In a variant of the technical solution, information symbols are located on the outer surface of the diffuser.

In a variant of the technical solution, information symbols are located on the inner surface of the base.

In an embodiment of the technical solution, the LEDs are placed in a tube made of optically transparent material.

In a variant of the technical solution, the internal space between the base and the diffuser is filled with a transparent polymer.

Installing a shelf with lights at an angle to the base allows you to reduce the number of lights and provide better uniformity of the surface glow with information symbols.

The use of LEDs will make it possible to increase the life of the panel by at least 200 times in comparison with the prototype.

The presence of an ambient light sensor connected to a power supply and control unit located on the outer surface of the panel saves energy and provides the possibility of a good perception of information at different levels of ambient light.

Various options for the location of the shelf with LEDs at an angle to the base and the diffuser will ensure uniform distribution of the light flux over the surface with the image of an information symbol, depending on the type of LEDs used. The uniform distribution of the light flux is obtained due to the fact that the inner surface of the base has a reflective coating and is made with corrugations.

The location of the information symbols on the inner surface of the diffuser ensures the panel is protected from external influences.

The location of the information symbols on the outer surface of the diffuser allows you to quickly change the information symbols.

The location of information symbols on the inner surface of the base expands the information capabilities of this panel.

The placement of LEDs in a tube made of optically transparent material allows you to simplify the installation of lighting devices.

If the internal space between the base and the diffuser is filled with a transparent polymer, then such a panel acquires the properties of a solid monolithic material, practically not subject to external influences.

The universal LED information panel is illustrated by 8 figures.

In Fig.2 there is a front side of the panel.

Fig. 8 is a circuit diagram of a panel.

Universal LED information panel is arranged as follows. The body of the board has a plastic base 1 (Fig.1, 2), made in the form of a rectangular plate, for example, of polycarbonate. The inner surface of the base is covered with a reflective layer (not shown in FIG.). The inner surface of the base can also be provided with corrugations (not shown in FIG.). On one side of the base, perpendicular to its plane, is a flat shelf 2 made of the same plastic material as the base. On the surface of the shelf facing the base, there is a board 3 with LEDs 4. The LEDs 4 are mounted on the board 3 so that the central axis of their light fluxes run parallel to the plane of the base 1. Between the outer edge of the shelf 2 and the second edge of the base 1 there is a diffuser 3, made of transparent plastic material. To increase the uniformity of the glow, the surface of the diffuser can be matted. When viewed from the side, the whole structure takes the form of a right-angled triangle, one, the smaller leg of which is a shelf 2, and the diffuser 5 is the hypotenuse. On the sides, the body is closed by plastic side plates 6, which can be coated with a reflective layer on the inside. The inner side of the diffuser 5 is equipped with information symbols made in the form of a stencil. The stencil can be positive 7 ', i.e. with dark information symbols on a transparent background or negative 7 ″, i.e. with luminous symbols on an opaque, dark background.

In technical solutions, information symbols are applied to the outer surface of the diffuser.

In a variant of the technical solution, information symbols are printed on the inner surface of the base.

A combination of the application of information symbols at once on all indicated surfaces is allowed.

On the outer surface of the shelf is installed an ambient light sensor (DVO) 8 with an automatic on and off switch. Inside the panel, on one of the side plates 6, there is a power and control unit 9. For fastening to the bearing surface, the base is provided with loops 10. In turn, the LEDs 4 can have a certain emission spectrum, for example yellow or white, or have a different emission spectrum, for example, red and yellow, or red and white. In the last two cases, the LEDs are evenly distributed on the surface of the board (figure 3) in alternating order. The total number of LEDs, their density on the board, depends on the size of the information surface of the panel, the power of the light sources used and the angle of distribution of their light fluxes.

In an embodiment of the technical solution, the shelf 2 with the board 3 is located at an acute angle to the plane of the base and perpendicular to the plane of the diffuser 5 (figure 4). In this case, the LEDs on the shelf are installed so that the central axis of their light fluxes are parallel to the surface of the diffuser. When viewed from the side, from the side of the side plate, this design also represents a right-angled triangle in which the hypotenuse is the base, and the legs of the shelf 2 and the diffuser 5.

In an embodiment of the technical solution, the shelf 2 with LEDs 4 and the LEDs on it are located so that the central axis of the light fluxes of the LEDs pass at an acute angle both to the surface of the base and to the surface of the diffuser 5 (Fig. 5). Moreover, in one of the options, when viewed from the side, the panel resembles an isosceles triangle, the sides of which formed by the base and the diffuser are approximately equal to each other.

In an embodiment of the technical solution, the light source is made in the form of a light tube 10 (Fig. 6) made of an optically transparent material into which LEDs 4 are inserted at a certain distance. In the tube, the LEDs are located along it (Fig. 7), and their light fluxes are directed one way. To create a unidirectional light flux, the light tube is equipped with a reflector 11. The LEDs in the tube can be arranged so that the central axis of their light fluxes are directed perpendicular to its axis. For such a tube embodiment, a reflector may not be required. The tube is attached to the inner surface of the shelf. In this case, it is permissible to perform the panel in accordance with all the listed options for the location of the shelf.

In a variant of the technical solution, the internal space between the base 1, the shelf 2, the side plates 6 and the diffuser 5 is filled with a transparent polymer, which hardens after filling the specified space of the panel.

Electrically, the LEDs 4 of the universal LED information panel are connected in series-parallel circuit (Fig. 8) and receive power from an external AC or DC network through a voltage conversion and control unit 9. A DVO 8 is connected to block 9.

Universal LED information panel operates as follows. When you turn on the light devices 4, the light flux permeates the entire interior of the panel. The surface of the diffuser is 5 s

information symbols 7 is partially illuminated by direct light, and partially reflected from the base 1. The proportion of these light fluxes depends on the location of the shelf 2 with respect to the surface of the base and diffuser and the angle of distribution of the light flux from the LEDs. The mirror surface of the base and the corrugation on its surface contribute to a uniform distribution of the light flux over the surface of the diffuser. If information symbols are placed on the inner surface of the base, then a somewhat diffuse display of them will be formed on the diffuser, which may be more attractive, especially for advertising purposes.

Various options for the location of the shelf (figures 1, 4, 5) make it possible to form a uniform distribution of the light flux over the surface of the information field, depending on the type of LEDs used and the size of the panel.

The use of a light tube (6, 7) will simplify the installation of light sources and provide increased moisture resistance of the panel.

If the inner space of the panel is filled with a solid transparent polymer, then such a panel acquires the properties of a monolithic durable device, practically not subject to destruction and moisture.

The presence of DVO allows saving energy, provides a normal perception of information at various levels of ambient light, and helps to increase the life of LEDs. The signal from the TWO depends on the level of ambient light. The higher the ambient light, the higher the signal from the light sensor and the lower the light output of the LEDs. The ratio of the sensor signals and the light flux of the LEDs is calculated so that the total light flux remains at a predetermined level, which allows to reduce electricity consumption in high ambient light conditions and automate the process of turning on the panel during dusk. Energy saving is also determined by the use of LEDs themselves, since their energy consumption is at least three times less than that of incandescent lamps.

If LEDs with different colors are used, then by adjusting the current of individual groups of LEDs of different colors, you can change the total color gamut of the light panel as a result of adding light fluxes. To do this, the knobs of the regulators should be placed on the outside of the panel.

A large number of light sources - LEDs of relatively low power makes it possible to regulate in a wide range the overall brightness of the panel or individual areas of its information surface by changing the brightness of individual groups of LEDs, or by turning off some of them.

The panel can be attached or suspended in any position to any bearing surface by any known means, including using mounting loops 10. Moreover, a certain inclination of the surface with information symbols to the side, the observer will provide a better perception of information. The panel can also be used on vehicles. In this case, it is allowed both power supply from an external or on-board network, and from an autonomous source. Since the power consumption of LEDs is several times less than that of incandescent lamps, the energy of an autonomous source is enough for a long period of time.

The proposed panel can be used as a license plate of a vehicle. At the same time, the panel should be positioned so that the shelf with the lighting devices is at the bottom.

The versatility of the panel is determined by the fact that it can be used both as an information board for various purposes, and as a pointer, and as an advertising element, and as a lighting device, and as a license plate table. It can be mounted in any position to any stationary surface or to a vehicle. The panel can be powered from an alternating current network, from an on-board direct current network, or from any type of autonomous power supply. You can enter operational information on the outer surface of the diffuser or form it on the inner surfaces of the diffuser or base. The color of the glow can also be changed if LEDs with different emission spectra are used. Various options for the proposed panel expand the possibilities of its application. The weight of the product is small, and the cost is determined mainly by the cost of the used light sources.

The technical and economic advantages of the proposed LED panel are as follows:

1. Reduced the complexity of manufacturing and weight of the product.

2. The cost of the product is reduced by reducing the complexity.

3. Increased product life through the use of LEDs.

4. Simplified installation.

5. Achieved great versatility due to the large number of product modifications and application possibilities.

6. Now you can adjust the color of the panel.

7. Reduced energy consumption, both due to the use of LEDs, and as a result of the use of DVO.

8. Reduced material consumption of the panel.
