Description

The invention relates to the field of information equipment, and specifically to thin light panels that use the technology of end lighting.

The product used as an information light panel has several names: thin light panel, framelight, frameled, led panel, LED panel. Panels are used as signs, signs, billboards and the like. The main advantage of a thin light panel is the ability to change the informational, advertising image without using tools. The design has a minimum thickness of about 20-25 mm, while the so-called end lighting technology is used to illuminate the advertising field. Its essence is that Plexiglas (acrylic glass) is used as a diffuser with backlight elements directing light from the ends to the surface. The ends of the plexiglass are polished to provide maximum light transmission.

Known information light panel (RF patent No. 85730, publ. 10.08.2009) containing a backlight panel made in the form of a plate of transparent light-scattering material, along the ends of which a series of LEDs. A translucent information element with an opaque or partially transparent semantically perceptible image is located on one of the longitudinal sides of the backlight panel. The backlight panel with an information element is placed in the case and fastened with screws.

The disadvantage of the panel is the need to use tools to replace the information element.

A thin light panel with LED end lighting is known (PRC patent No. 202495223, publ. 17.10.2012) containing a base frame and a front frame attached to it in the form of a sash using a vertical hinge (loop) connection. A translucent information element is placed between the frames. Magnets are placed in the front frame to fix it in a closed state relative to the base frame. The profile of the frame is made with grooves for accommodating panel elements, in particular glass for end illumination, an information image and a protective sheet of plastic to protect the information image.

The disadvantage of the panel is the impossibility of its use in a limited space, because to replace the information element, it is necessary to open the front sash frame. Another disadvantage of this technical solution is the lack of elements for fixing the spatial position of the information element, which leads to a gradual "sliding" down of the information element with the formation of horizontal folds.

The closest technical solution, selected as a prototype, is an information light panel with LED end lighting (South Korean application KR No.20100002407, published January 7, 2010), containing a base frame and an external (front) frame attached to it in the form of a sash. In this case, the outer frame is interfaced with the base frame by means of a horizontal swivel, so that the outer frame opens upward. In the frame of the base there is a sheet material made with the possibility of end lighting. The outer frame is provided with a protective sheet material. Between these sheets there is a translucent informational image, for fixing the position of which the base frame has a spring element, which ensures that the information image is pressed against the sheet material of the base frame. Magnets are placed in the outer frame to fix it in a closed state relative to the base frame.

The profile of the base frame and the profile of the outer frame used for their manufacture are known from the same document. The profile of the outer frame is made with grooves for placing a protective sheet of plastic to protect the information image, magnets and sealing elements. The profile of the base frame has a cavity for accommodating sheet material with end illumination and backlight elements.

A disadvantage of the known panel is the impossibility of its use in a limited space, because To replace the information element, it is necessary to open the external sash frame. In addition, the manufacture and subsequent assembly of the panel with a hinged connection between the base frame and the external frame places high demands on the accuracy of manufacturing the profile and subsequent assembly of the panel. The disadvantage of this technical solution is the impossibility of manufacturing panels of large sizes, for example 2050 × 3050 mm. These disadvantages are due to the configuration of the profiles used for the manufacture of the framework framework and the outer frame.

The production of information panels in the Russian Federation is most often carried out on order, according to the size of the customer. Accordingly, the production is single or small-scale, in connection with which the manufacturing and assembly processes are subject to increased requirements for manufacturability.

The objective of the invention is to improve the manufacturability of the manufacture of the information panel.

The technical result is to simplify the design of the information panel, its manufacture and operation.

The specified technical result is achieved by the fact that in the information light panel containing the base frame and the external frame conjugated to it, an information image made of light-transmitting sheet material placed between the first optically transparent sheet material mounted in the frame of the base, configured to end-illuminate, and installed in the outer frame of the second optically transparent sheet material designed to protect the information image, and the fixing element an informational image, wherein the base frame is made of non-magnetic material and provided with a strip of magnetic material, and the outer frame is magnets designed to fix the position of the outer frame relative to the base frame, according to the invention, the base frame and the outer frame are each of four segments of a hollow semi-closed profile, having a C-shaped groove in the cross section on the reverse side, in which fixing corners are placed that fasten the said sections of the profile with each other to form m of rectangular framework of the base and the outer frame, while the mounting angles are fixed in the aforementioned C-shaped groove with screws screwed into through threaded holes made in the mounting corners, until it stops in the wall of the aforementioned C-shaped groove, the profile of the base frame on the front side has an additional C-shaped groove in cross section for placing a strip of magnetic material, and on the bottom side a U-shaped groove for placing the first sheet material and located above, partially open towards the last a channel for accommodating end lighting elements of the first sheet material, the profile of the outer frame on the lower side has a U-shaped groove in cross section to accommodate the second sheet material, where the aforementioned C-shaped groove on the back side of the profile of the outer frame, designed to accommodate mounting angles, is adapted also for placing magnets, while behind the specified C-shaped groove in the direction from the front side of the profile to its reverse side, a U-shaped cavity is formed to provide the aforementioned the external frame with the base frame, and the element for fixing the position of the information image is formed by the end surface of the wall of the U-shaped groove of the profile of the external frame located closer to the reverse side of the specified profile, and the surfaces of the first and second sheet materials facing the information image when the information light panel is in assembled condition.

It is advisable that the strip of magnetic material placed in an additional C-shaped groove of the front side of the profile of the base frame, is evenly distributed around the perimeter of the base frame. Moreover, the first optically transparent sheet material can be made in the form of a package assembled from at least two sheets of sheet material.

In addition, it is desirable from the side of the wall of the U-shaped groove of the outer frame profile, located closer to the front side of the specified profile, to make a channel for accommodating the sealing element, partially open towards the U-shaped groove, and from the side of the wall of the U-shaped groove of the profile of the base frame located closer to the reverse side of the specified profile, make a channel for placing a sealing element, which is partially open towards the U-shaped groove. At the same time, the sealing elements placed in the respective channels of the base frame and the outer frame should be able to compress the first and second optically transparent sheet materials towards each other when the information light panel is in the assembled state.

It is also advisable to adjust the C-shaped groove on the back side of the profile of the base frame, designed to accommodate the mounting corners, to accommodate the biscuits of the suspension of the information panel.

The indicated technical result is also achieved by the fact that an aluminum molded profile is used to manufacture the base frame of the information light panel, and by the fact that an aluminum molded profile is also used to manufacture the outer frame of the information light panel.

Position A indicates the mounting gap between the frames 1 and 2 of the information panel assembly.

The information light panel consists of the frame 1 of the base and the outer frame 2. In the frame 1 of the base, a first sheet optically transparent material 3 is installed, made with the possibility of end illumination. In the outer frame 2, a second sheet optically transparent material 4 is installed. Between the sheet material 3 and the sheet material 4 there is an information image 5 made of light-transmitting sheet material (film, paper).

The sheet material 4 is intended to protect the information image 5 from external influences and to fix the position of the image 5 inside the panel.

As the first optically transparent material 3, a special acrylic glass is used, designed for the so-called end lighting. This material is widely marketed by various manufacturers.

As elements of the end illumination, LEDs are used (LED strip) 6. LEDs 6 are installed in the corresponding channel of the profile of the base frame 1. When designing a light panel, you should adhere to the recommendations of the manufacturer of acrylic glass according to the dependence of the thickness of acrylic glass on the characteristics and number of LEDs, as well as the size of the advertising field.

To keep the panel in the assembled state, fixing the position of the outer frame 2 relative to the base frame 1, magnets 8 are used, which are installed in the outer frame 2, interacting with a strip 7 of magnetic material placed in the corresponding profile groove in the frame 1 of the base.

Each of the frames (base frame 1 and the outer frame 2) are made of four segments of the corresponding profile, which are fastened by fixing angles 9 to form a rectangular frame.

The profile of the base frame 1 is made of linear hollow semi-closed aluminum profile. A cross section of this profile is shown in FIG. four.

On the reverse side of the profile of the base frame 1, a C-shaped groove 10 is formed. The groove 10 is designed to accommodate the mounting corners 9. In the specified groove 10, if necessary, also suspension hangers (not shown) of the information panel are placed.

The aluminum profile of the base frame 1 on the front side has an additional C-shaped groove 11. The groove 11 is designed to accommodate a strip 7 of magnetic material. A strip 7 of magnetic material can be distributed evenly around the perimeter of the base frame 1 or discretely, in separate fragments.

On the bottom side, the profile of the base frame 1 has a U-shaped groove 12. The groove 12 is designed to accommodate the first sheet material 3. Above the groove 12, a channel 13 is made, partially open towards the groove 12 to accommodate the LEDs 6, which provide end illumination of the material 3. From the side the left wall 14 (according to the drawing, see Fig. 4) of the U-shaped groove 12, located closer to the reverse side of the profile, a channel 15 is made for accommodating the sealing element 16. The channel 15 is partially open towards the U-shaped groove 12.

In the aluminum linear profile of the base frame 1, additional elements are formed that improve the characteristics of the manufactured information panel. In particular, the channel 15 for accommodating the sealing element 16 is made with additional walls 17 and 18, to ensure the accuracy of extrusion of the specified channel 15. To reduce the weight and material consumption of the product, cavities are made in the profile of the base frame 1. To reduce the visual thickness of the information panel, the upper part of the profile frame 1 of the base is made stepwise, with a decrease in the height of the profile in the direction of its reverse side.

The profile of the outer frame 2 is also made of linear hollow semi-closed aluminum profile. A cross section of this profile is shown in FIG. 5.

The aluminum profile of the outer frame 2 on the lower side has a U-shaped groove 20. The groove 20 is designed to accommodate the second sheet material 4. From the side of the right wall 21 (according to the drawing, see Fig. 5) of the U-shaped groove 20, located closer to the front side of the profile of the outer frame 2, a channel 22 is made for accommodating the sealing element 16. The channel 22 is partially open towards the U-shaped groove 20. On the reverse side of the profile of the outer frame 2, a C-shaped groove 24 is formed. The groove 24 is designed to accommodate mounting angles 9 .In the specified groove 24 times eschayutsya as magnets 8. During the C-shaped groove 24 in a direction from the front side of the profile to its back side formed a U-shaped cavity 25. The cavity 25 is intended for mating the outer frame 2 and frame 1 base.

The conjugation of the frames 1, 2 for assembling the information light panel as a whole is carried out by placing the C-shaped groove 10 of the profile of the base frame 1 in the U-shaped cavity 25 of the outer frame 2. The position of the outer frame 2 relative to the base frame 1 is carried out by magnets 8 installed in a groove 24 of the outer frame 2 interacting with a strip 7 of magnetic material placed in the C-shaped groove 10 of the profile of the base frame 1.

The placement of magnets 8 in the groove 24 of the outer frame 2 provides the formation of a geometric outline profile of the frame 2, optimal from the point of view of simplifying the operation of the information panel, because allows you to remove the outer frame 2 with your hands to replace the information image without the use of any additional tools (suction cups, hooks, blades, screwdrivers, etc.). For the same purposes, the geometry of the cross sections of the profiles of the base frame 1 and the outer frame 2, more precisely, the external dimensions of the C-shaped groove 10 of the profile of the base frame 1 and the dimensions of the U-shaped cavity 25 of the outer frame 2 are selected so that taking into account the height of the magnet 8 and the thickness of the strip 7 to ensure the formation of a uniform gap A (see Fig. 6) between the frames 1 and 2, when the panel is in the assembled state.

The cavity 25 of the profile of the outer frame 2 has a protrusion 26 located in its lower part, designed to position the frame 2 relative to the frame 1.

The above-described method of assembling the finished panel, positioning the outer frame and the base frame reduces the complexity of installation and the complexity of replacing the information image. Also, this connection reduces the likelihood of moisture and dust getting into the panel.

The profiles of the outer frame and the base frame have the same section height. This approach to the formation of profiles greatly simplifies the manufacture of panels, in particular cutting profiles. It is not necessary to rebuild the equipment when switching from cutting the profile of the base frame 1 to cutting the profile of the outer frame 2 and vice versa. In addition, the calculation of the lengths of the sections of the profiles for the frame 1 of the base and for the outer frame 2 is the same.

In the linear aluminum profile of the outer frame 2, additional elements are also formed that improve the characteristics of the manufactured information panel. In particular, to reduce the weight and material consumption of the product, cavities 27 are made in the profile of the outer frame 2 of the base. The front part of the profile is made in the form of a single rounded plane 28 with a decrease in the width of the profile to the bottom, which also reduces the material consumption of the product and emphasizes the ease of construction.

Information light panel is made as follows.

Pre-prepared acrylic glass of the required size (first sheet optically transparent material 3). The ends of the glass, on the side of which the LEDs are installed, must be polished to a glossy surface or cut off with a laser. The ends, from the side of which the LEDs are not installed, must be sealed with a white light-blocking film. This provides reflection of light from the ends and better illumination of the glass surface. If the glass has a thickness of 8 mm (this is the maximum available on the market), then its back wall should be covered with light-blocking material 23 (white film, thin plastic sheet, etc.) to reduce light loss. If the glass has a thickness of less than 8 mm, it is necessary to assemble a sandwich of glass for end lighting and light-blocking material 23 of greater thickness.

Different sizes of glass for end lighting require a different number of LEDs 6: for small sizes, it is enough to install an LED strip for illumination on one side, large sizes, in particular 2050 × 3050 mm, require the installation of an LED strip on four sides. The decision on the number of parties from which it is required to install LEDs 6 is determined empirically by measuring the illumination on the resulting finished product. As a rule, illumination is normalized in the terms of reference for the finished product (light panel).

For the manufacture of the base frame 1, four pieces of linear aluminum profile are sawed in accordance with the dimensions of the manufactured panel or prepared acrylic glass, for example 2050 × 3050 mm. Profile cutting is carried out at an angle of 45 degrees.

Mounting angles 9 are installed in the C-shaped grooves 10 of the reverse side of the profile and fixed in them by screws 29. First, the three sides of the frame 1 are assembled. An LED strip (LEDs 6) is laid in channel 13 and then, in the U-shaped grooves 12 of the profile, prepared glass (optically transparent material 3). In additional C-shaped grooves 11, strips 7 of magnetic material are laid. The sealing elements 16 are laid in the channels 15. The fourth side of the frame 1 is installed together with the corners 9. Then, with the screws 29, all four corners 9 are finally fixed in the grooves 10. The screws 29 are screwed into the threaded holes of the corners 9 until they stop against the surface of the groove 10. The base frame 1 is ready.

Similarly, the outer frame 2 is assembled.

Four segments are sawed off from the corresponding linear profile at an angle of 45 degrees. Mounting corners 9 and magnets 8 are installed in the C-shaped grooves 24 of the reverse side of the profile. The sealing elements 16 are laid in the channels 22. The protective sheet material 4 is cut to size. Three sides of the frame 2 are assembled. Protective material 4 is installed in the U-shaped grooves 21, the fourth side of the frame 2 is installed and fixed. The outer frame 2 is ready.

Information light panel is used as follows.

The frame 1 of the base with the help of crackers suspension (not shown) is fixed to the wall. The LED strip (LEDs 6) is connected to the electrical network. An information image 5 is placed in the outer frame 2, on the surface of the sheet of protective material 4, so that its edges are in contact with the ends of the walls 21 of the U-shaped groove 20 of the outer frame 2. If necessary, the edges of the information image 5 are fixed with transparent tape. The outer frame 2 is superimposed on the base frame 1 so that an additional C-shaped groove 11 with the strip 7 installed in it enters the U-shaped cavity 25 of the outer frame 2 (see Fig. 6). In this case, the magnets 8 are attracted to the strip 7 and fix the frame 2 relative to the frame 1. Due to the fact that the corners 9 are located on the back side of the profile of the frame 1, an even, smooth contact surface of the magnets 8 with the strip 7 is formed on the front side.

The position of the information image 5 is fixed by the end surface of the wall 21 of the U-shaped groove 20 of the profile of the outer frame 2, located closer to the reverse side of the specified profile, and the surfaces of the first and second sheet materials 3 and 4, facing the information image 5, when the information light panel is in assembled condition. Due to the springy properties of the sealing elements 16, additional pressing of the sheet materials 3 and 4 to each other is carried out.

Replacing the information image 5 is carried out in the reverse order without using any tool, which is one of the main operating requirements for light panels. The absence of the need to use any tool to replace the information image is ensured by the presence of a guaranteed gap A between the base frame and the outer frame of the information panel assembly. This simplifies the operation of the claimed information panel.
