INFORMATION TABLE

The utility model relates to the field of development of devices for the visual display of information, mainly to information light displays as route indicators for installation in vehicles involved in route passenger transportation. Also, a useful model of a backlit information board device can be used for the production of various utilitarian and service light indicators, advertising panels and signs.

Patent documents are known that describe various light panels, the principle of which is based on the use of light sources placed in frames of various designs. The front surfaces of light panels are used to apply various information, and the structures use reflective and scattering surfaces, transparent plates, for example:

"LED information panel of a vehicle." JP 2011081244 (A), IPC G09F 13/04, G09F 13/18 publ. 04/21/2011

The disadvantages of the above technical solutions are the complexity of manufacturing, material consumption of the product.

An information board is known that contains a box-shaped case expanding downward with a lid and a fixed information carrier, the light source being installed in the case, and the information carrier being easily removable, made of plastic, and the cover is easily removable. The well-known information board is designed as a route indicator for buses. See patent for utility model of the Russian Federation No. 79704 U8, IPC G09F 13/00, publ. January 10, 2009

The disadvantage of this solution, if it is used for the route indicator, is the difficulty of fastening, and the inconvenience of further maintenance and dismantling if necessary, as the authors propose gluing the information board directly to the surface of the windshield, in addition it has a relatively large weight, since lamp sources are used Sveta. It is difficult to fasten the box body and the cover together, for which it is proposed to use options for a special quick-detachable connection, which requires additional production costs. And finally, the implementation of the lid with the window complicates the design, while the absence of a light reflector with a one-sided arrangement of the light source does not contribute to uniform light distribution, and this negatively affects the recognition of information.

The well-known "Information light panel" see patent for utility model of the Russian Federation No. 85730, IPC G09F 13/00, publ. 08/10/2009, having a small thickness lying in the range of 5-25 mm, made using organic light emitting diodes as a source of illumination, made in the form of a uniform plate of translucent material, at least along one part of the side of the backlight panel there is a row of LEDs with the orientation of the direction of the light flux towards the opposite side of the backlight panel, while at least one of the longitudinal sides of the backlight panel is a translucent information element with an opaque an obscure or partially transparent semantically perceptible image made in the form of a coating of self-adhesive polymer material, the panel is made with a substrate located relative to the backlight panel with a gap and with the surface facing the backlight panel diffusely reflecting light.

The design of the described solution seems to be non-technological due to the difficulty of connecting all the components of the light panel together, and uneconomical because of the need to use high-quality and expensive light-conducting and light-scattering materials to ensure the approved uniformity of light distribution with single-sided illumination, or an additional light-emitting series for double-sided illumination. Due to these shortcomings, the time and cost of producing light panels increases.

Closer in technical essence, an analogue to the claimed utility model is a light panel described in utility model No. 543481 of the Russian Federation "Universal LED information panel" IPC G09F 9/00, B60Q3 / 04 publ. 05/10/2006

Known light panel contains a diffuser, information symbols made in the form of a stencil, a housing with a base and LED light sources located inside the housing at a certain angle to the diffuser. In this case, the surface of the diffuser with information symbols is partially illuminated by direct light, and partially reflected from the base. Known light panel has a relatively low weight.

A disadvantage of the well-known universal LED information panel is manifested in the case of its use as a route indicator, namely, in the relatively large width of the panel when viewed from the side, since it has the shape of a rectangular triangle in cross section, which makes it difficult to mount it inside the vehicle parallel to any surface in conditions of deficit of free space and intersections with the functional space, in addition, with such a triangular section and the use of flat walls of the diffuser and the base It becomes difficult to achieve uniform illumination of information symbols, for this purpose it will be necessary to use a very high-quality material of the diffuser and strive to increase the reflective properties of the base, for example, to resort to its corrugation, as proposed by the prototype authors, and the use of a large number of LEDs, which increases the complexity and total cost of production products.

In addition, the analog does not think of a way to firmly bond all the components together, which is an important condition for the manufacturability.

An analogue similar in technical solution is also known, described in the source D1-US 5428912 A, IPC F21V 8/00, G09F 13/04, G09F 13/02, G09F 13/00, published July 4, 1995; and a disclosing information board comprising a housing with a light transmitting front surface and an internal cavity in which a rigid printed circuit board with LED light sources and a reflector with an inclined plane are fixed, wherein the light radiation is directed mainly parallel to the plane of the light transmitting part of the housing. This analogue can be taken as a prototype.

Although the authors of the prototype mention as one of the goals of the design solution - providing the ability to replace information symbols, as well as a smooth and uniform distribution of light on the front surface, the disadvantage of the prototype is the non-obviousness of the method of reliable mounting of the front panel with information symbols, the corresponding possibility of its easy replacement, as well as

simple methods for such a replacement are not described. Perhaps it is intended to replace the entire body or one front wall. Another disadvantage is the lack of uniformity of light distribution on the front surface. Due to the constant value of the angle of inclination of the reflector along almost its entire height with respect to the axis of the predominant direction of light emission and due to the fact that the beginning of the reflector is in close proximity to the light source, in this design it is not possible to avoid a difference in the illumination power of the front surface of the board : the closer to the source, the brighter the surface that was experimentally identified. Given the link in the description of the prototype to its closest analogue, in which the direction of radiation of light sources is perpendicular to the front surface (and in this case obvious light spots are visible), the authors of the prototype first of all solved the problem of smooth distribution of illumination and only then uniformity. At the same time, the design of the information board can be simpler and with more uniform illumination, with the possibility of replacing the element containing the information.

The tasks are to develop a bulletin board with easily replaceable information, made in the form of a simple and reliable design, having both light weight and small thickness, within 27 mm, combined with the simplicity and versatility of its operation, installation, dismantling and maintenance in vehicles as route indicator. Also the task includes optimization and reduction of the production process by reducing the number of components of the information board and using practical and inexpensive materials, with an aesthetic, uniform degree of illumination of the information displayed on the board, as well as the ease of electrical connection.

The main technical task of the claimed utility model is to increase the uniformity of illumination of the light transmitting front panel containing the information field.

The result is achieved due to the fact that the information panel is made in the form of a box-shaped case, in the shape of a section representing a rectangular trapezoid without a base with a step of an L-shaped profile at the edges, and the base of the trapezoid is a removable light-transmitting diffuser cover, which is the carrier of the information field, which closes the front, and inside the housing on the lower inner end surface of the light source is installed in the form of an LED strip,

and on the inner surface of the rear wall of the body, starting from the second third in height, a diffuse-reflective material is applied, in addition, the back wall of the body, starting from the middle in its height, changes its direction from vertical to inclined, towards the edge of the larger base of the trapezoid, opposite the light-emitting side, forming together with a diffuse-reflective layer a light-guiding reflector surface. The box-shaped case along the entire perimeter of the leading edge has an L-shaped profile into which the diffuser cover is inserted and can be fixed due to the minimum allowances and elasticity of the diffuser cover material.

The diffuser cap is made of light-transmitting plastic sheet having a small thickness, resistant to UV radiation and temperature extremes, on the surface of which information symbols are applied in any way, for example, by direct printing, or a self-adhesive polymer / polyvinyl chloride PVC film with information symbols. For the manufacture of a diffuser cap, a translucent honeycomb polycarbonate of 4 mm thickness is preferable because of its suitable physical characteristics and minimal cost in comparison with other materials with the required properties.

The box-shaped case can be made of dark, opaque plastic of any kind, which is resistant to UV radiation and temperature extremes. Preferred are ABS (acrylbutadiene styrene) or PVC (polyvinyl chloride) plastic. Since the information panel may be in the field of view of the driver of a fixed-route vehicle, the back of the panel should prevent the penetration of light from a radiating source into the vehicle interior. The use of dark plastic color for the case helps to ensure greater opacity even for the cheapest and thinnest sheet materials in order to prevent light from penetrating from either side of the box-shaped case of the route indicator, as well as reduce excessive light reflection inside the information panel from the back wall of the box-shaped case in that part of it closest to the light emitting surface of the diode strip.

The application of diffuse reflective material to two-thirds of the rear wall of the box-shaped body far from the light source helps to increase the intensity of reflected light rays on the surface of the diffuser lid, which is as far as possible from the light-emitting surface, which creates a more uniform illumination of information symbols.

As a reflective material, a self-adhesive polymer film, or a white glossy or matte paint coating on two thirds of the area of the rear inner wall of the box-shaped body, starting from the edge opposite the light source, is recommended.

As a light-emitting source, an LED strip is glued onto the inner end plane of the box-shaped body, the optical radiation of which is mainly directed perpendicular to its base, parallel to the plane of the front surface and towards the side of the body having a slope. A LED strip with a base width of 0.7 mm, with a self-adhesive base and a frequency of 120 diodes is recommended in the art. per meter, suitable for connection to sources with a constant voltage of 12 V, due to its easy availability on the market, low price and the necessary brightness in relation to length. On either side, the tape is connected in any way to the wires that go to the power source; in a vehicle, it can be connected by a wire of the required length to the power supply through the cigarette lighter plug or to the wiring of the side lights, for example, directly or via a detachable connection. In vehicles whose voltage is different from 12 V, you must use the appropriate power supply.

The essence of the proposed technical solution is illustrated by drawings:

FIG. 5 is a perspective view of a part of a bulletin board without a cover, a view of the rear wall and the lower end wall of the box body for illustrating the location of the LED strip (with a schematic indication of the direction of optical radiation);

FIG. 7 - Schematic representation of the cross section of the information board with visualization of the path of direct and reflected light radiation from the source.

The information board (route indicator) contains a box-shaped case 1 having a cross-section in the shape of a rectangular trapezoid, the base of which is the diffuser cover 2, inside the case 1 has an LED strip 3 glued to the lower end surface of the case 1, light radiation is directed parallel to the surface of the diffuser cover 2 towards the inclined surface of the housing 1.

On the inner part of the rear wall of the housing 1 having a bent shape, two-thirds of its area, starting with the opposite edge of the light source, is coated with diffuse reflective material 4, which is a self-adhesive glossy or matte polymer / polyvinyl chloride (PVC) film of white color, or white paint applied in any way. In FIG. 7 shows a control circuit and distribution of light radiation using a diffuse reflective material.

The removable diffuser cover 2 has a layer of information field 5 on it, which can be made by any of the available methods: for example, by direct printing on the diffuser cover 2, either by screen printing from a self-adhesive PVC film or by gluing a PVC film containing printed on it information symbols.

The L-shaped profile running along the perimeter of the front edge of the housing 1 has a horizontal surface of small width - a step 6, on which a removable diffuser cover 2 rests, and a vertical side surface 7, which holds the removable diffuser cover 2 from displacement.

A removable diffuser cover 2 with a layer of information field 5 is applied with a minimum gap to the size of the socket formed by the bead 7 of the L-shaped profile of the body 1, for a snug fit to it, which prevents spontaneous opening, but slightly exceeds the height of the bead 7 of the L-shaped profile so that the diffuser cover 2 with the applied information layer 5 can be removed without difficulty.

The housing 1 has openings 8 for the possibility of connecting the insulated wire 9 to the LED strip 3 on both sides, depending on the location of the information board inside the vehicle. The holes can be replaced by recesses in the front edge of the housing.

It should be noted that applying the information field 5 in any way to the diffuser cover 2 further assumes the integral and indivisible use of the diffuser cover 2 with the information field 5, that is, the lid itself becomes an information carrier. And since the cover is made easily removable and in accordance with the dimensions of the socket formed by the L-shaped profile of the front edge of the housing 1, it can be easily replaced with the same cover with other information applied to it. This feature is distinguishing, as is the use of new body geometry with a sectional shape in the form of a rectangular trapezoid, the use of simple and accessible materials, and an easy way to connect, fix, replace.

To operate the bulletin board as a route indicator, it is important to provide a place and a method for attaching it to the vehicle. The small weight and thickness of the proposed solution allows you to easily attach a bulletin board by any materials and by any known means to the required bearing surfaces, for example, detachable fasteners to the vehicle glass from the inside, double-sided adhesive tape to the glass from the inside. We will separately consider fixing the claimed information board in buses and minibuses. Since the presence and some characteristics of the route signposts of these modes of transport are regulated in Russia by regulatory documents, for example, GOST (before 1991), Resolutions (after 1991), it is possible to determine the optimal sizes of the route signpost from the documents governing passenger transportation his proper whereabouts. So, in the passenger bus of the “M2” category, the front direction indicator should be in the upper part of the windshield and at the same time not reduce the normative characteristics of viewing angles for the driver, and its vertical size should not exceed 140 mm. The claimed solution to the information board when performing the appropriate size, it is supposed to be used inside the vehicle, securing it to the sun visor on the right side along the side of the movement using two stationery rubber bands, or laces, clamps, or in any other convenient way. Such versatility and ease of attachment is due to the very small weight of the scoreboard, and its small thickness, which will not limit the angle of rotation of the sun

visor. The light information board can rise and fall together with a peak.

Thus, the technical result of the developed utility model is to increase the uniformity of illumination of the light-transmitting diffuser cap containing the information field.

Tests of the claimed utility model of the information board as routing indicators showed the reliability of the installation of the panel during its operation, aesthetic and uniform distribution of light on the surface of the cover with the applied information field, as well as easy dismantling and quick change of information by replacing the cover. When testing the information board, the optimal aspect ratio of the route indicator was revealed for the transport category “M2” with dimensions of 140 by 500 mm, at which the thickness of the cross section of the body can not exceed 27 mm.

The advantages of the claimed device information boards in reducing the weight and thickness of the product, reducing the cost of the product through the use of inexpensive and common materials, reducing the complexity of manufacturing. In addition, the service life of the product is increased due to the use of LED strip; simplified installation, replacement and maintenance; reduced material consumption information board.

A bulletin board may be manufactured using well-known process equipment. In particular, the cost of production of the main body can be reduced by molding it from plastic sheet materials on entry-level vacuum forming machines. With large runs, one can consider the production of cases on thermoplastic machines. The simple arrangement of the utility model allows its production even without special equipment, in a makeshift way in the presence of materials. The diffuser cover can be made of sheet honeycomb polycarbonate by simply cutting it to size, followed by applying information symbols using cut-out screen-printed PVC film, or by gluing a film with printing onto cellular polycarbonate, which allows you to use any color combinations that are used for color coding of intercity route directions by municipalities.

The inventive utility model is designed to meet modern concepts of convenience, regulatory characteristics and technical capabilities of visual information supply, while not requiring attachment to any complex technologies, and is intended for use also at such facilities that do not have specially designed structures or holders for bulletin boards.
