    [0004] Technical sector
    [0005]
    [0006] The present invention is related to the exposure of backlit laminar elements for advertising products or services in commercial establishments.
    [0007]
    [0008] State of the art
    [0009]
    [0010] The light boxes are widely used in commercial establishments for the exhibition of posters and backlit laminar elements, such as advertising, photography, shop signs or similar.
    [0011]
    [0012] The light boxes comprise lighting means for the projection of images, a laminar element, such as a textile sheet, which is arranged facing the lighting means and on which the images are projected, a rear laminar element and a perimeter frame where the fastening of the laminar elements and the lighting means is established, the fastening to the perimeter frame being conventionally established by means of bolted joints. See, for example, the documents, ES1067423U, US4242821A, US4418378A, US4989122A.
    [0013]
    [0014] The light boxes are elements that are subject to specific movements, where the employees of the commercial establishment have to move the boxes to position them at strategic points for their visualization, sometimes resulting in the light box being broken or due to its manipulation It spoils, so it is important that the boxes have sufficient structural rigidity to withstand the movements to which they are subjected. The risk of breakage or damage increases due to the fact that the light boxes are usually of sufficient size to be able to capture the attention of buyers, such as 2 meters high by 2 meters wide.
    [0015]
    [0016] On the other hand, the light boxes are devices that to attract the attention of the buyers must be kept in operation during the long period that the commercial activity lasts, or even during night periods outside the business hours, which It implies that the lighting means may need to be replaced due to their failure or for maintenance reasons, therefore it is necessary that the light box be easily mountable and removable to allow rapid replacement of the lighting means or other electrical elements, without the need to have to require special tools for the assembly and disassembly of its parts.
    [0017]
    [0018] Another problem related to light boxes is the means used to bring the power supply to the lighting means. Generally internal wiring is used that must be arranged inside the light box, which are exposed to breakages during the translation of the light box or during maintenance tasks, in addition to being able to break the overall aesthetics of the assembly, being the aesthetics of great importance in commercial elements exposed to the public.
    [0019]
    [0020] It is therefore necessary a light box with an improved structural configuration that allows it to be provided with sufficient rigidity that can withstand the manipulations to which it is subjected, which allows easy assembly and disassembly of its constituent parts and that has a passage from power supply to improved lighting means.

    [0100]
    [0101] Detailed description of the invention
    [0102]
    [0103] The invention relates to a light box available in commercial establishments for the representation of images of products or services using backlit laminar elements by means of a light emission source.
    [0104]
    [0105] The light box comprises lighting means (100) for the projection of the images to be represented, a first front laminar element (200) arranged opposite the lighting means (100) and on which the images are projected, a rear laminar element (300) that is arranged so that the lighting means (100) are arranged between the first front laminar element (200) and the laminar element rear (300), and a perimeter frame (400, 400 ') where the fastening of the lighting means (100), the first front laminar element (200) and the rear laminar element (300) is established.
    [0106]
    [0107] Preferably, as shown in the exemplary embodiment of Figures 1 and 2, the light box has a prismatic configuration of a square or rectangular shape, the first front laminar element (200) in which they are represented on its front the images, in its rear part the rear laminar element (300) and in its sides the perimeter frame (400, 400 '). With this configuration, the lighting means (1) project the images on the back of the first front laminar element (200) that is observed by the customers of the commercial establishment by the front of the first front laminar element (200).
    [0108]
    [0109] The perimeter frame (400, 400 ') is formed by two vertical stringers (400) and two horizontal stringers (400'), one of the two horizontal stringers (400 ') supporting the ground, for which said transverse stringer ( 400 ') has a few feet of support (500) to the ground.
    [0110]
    [0111] As seen in Figure 4, each of the stringers (400,400 ') comprises a first front housing (410) to house the first front sheet element (200), a rear housing (420) to accommodate the rear sheet element (300 ), a first channel (430) for the arrangement of electrical elements and a second channel (440) where first support pieces (600) are arranged.
    [0112]
    [0113] Additionally, the light box comprises a second front laminar element (not shown in the figures) that is arranged between the first front laminar element (200) and the lighting means (100). Accordingly, each of the stringers (400,400 ') additionally comprises a second front housing (450) to accommodate the second front sheet element, such that the second front sheet element is sandwiched between the first front sheet element (200) and the lighting means (100).
    [0114]
    [0115] Said second frontal laminar element has predefined representations in a specific area of its surface, so that by illuminating said specific zone, additional optical effects can be achieved on the first front laminar element (200).
    [0116]
    [0117] The front laminar elements have a reciprocal shape to the perimeter frame (400, 400 ') of the light box and slightly larger, and each has an oversized flange in its contour that is intended to be introduced into the respective front housing (410,450 ) of the stringers (400,400 '), so that the oversized flanges of each front laminar element guarantee adequate fastening of the laminar elements in the perimeter frame.
    [0118]
    [0119] The light box comprises vertical posts (700) that are arranged between the horizontal stringers (400 ') which have the main function of providing rigidity to the perimeter frame formed by the vertical (400) and horizontal stringers (400'), of so that the light box can be manipulated to be positioned in strategic points of the commercial establishment without risk to compromise its structural integrity.
    [0120]
    [0121] The vertical posts (700) have second support pieces (800) that are attached to the vertical posts (700) by an elastic jump joint.
    [0122]
    [0123] The horizontal stringers (400 ’) have third support pieces (460’) that are arranged at both ends of the horizontal stringer (400 ’), or the vertical stringer (400).
    [0124]
    [0125] The lighting means are LED panels (100) preferably square in shape that are supported by their corners between the support pieces (600,800,460 '), so that the LED panels (100) provide improved structural rigidity to the box light.
    [0126]
    [0127] The vertical posts (700) are separated from each other a predefined distance corresponding to the width of the LED panels (100).
    [0128]
    [0129] Preferably the panels have a plurality of RGB LEDs.
    [0130]
    [0131] The first and second support pieces (600,800) have regions (610,810) for supporting the corners of the LED panels (100), where one of said regions (610,810) has an inclined front that supports another reciprocal inclined front of the LED panel (100) for unequivocal mounting of LED panels (100) on support pieces (600,800).
    [0132]
    [0133] As shown in the figures, the LED panels (100) that are arranged in an intermediate location in the light box are supported between four of the second support pieces (800), while the LED panels (100) that are arranged in The sides of the light box, in contact with the stringers (400,400 '), are supported between two of the first support pieces (600) and two of the second support pieces (800), while the four panels are arranged in the corners of the light boxes are supported between one of the first support pieces (600), two of the second support pieces (800) and one of the third support pieces (460 ').
    [0134]
    [0135] As shown in detail in Figure 5, the LED panels (100) have the inclined front in their lower right corner, thus it is evident that all the second support pieces (800) have an inclined front, but only the first support pieces (600) located in the second channel (440) of the lower horizontal stringer (400 ') and of the right vertical stringer (400) have an inclined front. Likewise, only the third support piece (460 ’) that is located on the right end of the lower horizontal stringer (400’), or the lower end of the vertical stringer (400), has an inclined front.
    [0136]
    [0137] The regions (610,810) of the first and second support pieces (600,800) are separated by an edge (620,820) that has a conformation that fits into a reciprocal projection (110) of the LED panels (100) to establish a jump joint elastic panels to support pieces (600,800). The third support pieces (460 ’) also have a conformation to fit one of the projections (110) of the LED panels (100).
    [0138]
    [0139] By way of non-limiting example, the edge of the support pieces shown in the figures has a "T" shape where the upper part has the shape with a rounded shape that is intended to be inserted by elastic jump in the shoulder (110) of the LED panels (100).
    [0140]
    [0141] The first support pieces (600) have two regions (610) whose edge (620) establishes a respective "L" shape to support two corners of two of the LED panels (100), the second support pieces (800) they have four regions (810) whose edge (820) it establishes four respective "L" shapes to support one of the corners of four of the LED panels (100), and the third support pieces (460 ') have a single "L" shape to support a corner of one of the LED panels (100).
    [0142]
    [0143] The first support pieces (600) have an extension (630) for mounting the vertical posts (700). The vertical posts (700) have a rectangular section so that the ends of the vertical posts (700) fit by elastic jump in the extension (630) of the first support pieces (600. The extension (630) has teeth ( 631) that retain the vertical post (700) and prevent its accidental exit As shown in Figure 5, it is provided that the extension (630) has circular protuberances (632) that fit into reciprocal recesses of the vertical posts (700) to ensure retention of vertical posts (700) in the first support pieces (600).
    [0144]
    [0145] As can be seen in figure 5 and figure 9, the first support pieces (600) have a projection (640), arranged in its lower part opposite to the extension (630), which is intended to establish a retention of the workpiece. support (600) in the second channel (440) of the horizontal stringers (400 ') with respect to a tooth (441) of the second channel (440) (see figure 4).
    [0146]
    [0147] The second support pieces (800) have two lateral wings (830) that define a housing, preferably in a "U" shape, for fixing the vertical post (700) where the second support pieces (800) are arranged. Each side wing (830) has at its free end a tooth (831) that ensures the retention of the support piece (800) in the vertical post (700) preventing its exit. The joint action of the lateral wings (830) and the tooth (831) establishes an elastic jump fixing of the second support pieces (800) on the vertical post (700).
    [0148]
    [0149] The LED panels (100) have a handle (120) that projects vertically from the front of the LED panel (100) and which facilitates the disassembly of the LED panels (100) when they are supported and held in the support pieces ( 600,800,460 ').
    [0150]
    [0151] Additionally, each stringer (400,400 ') has a central housing (470) where knots (900) connect the vertical stringers (400) with the horizontal stringers (400'). The knots (900) have two parts, where each of the parts has a reciprocal shape to that of the central housing (470), one of said parts being intended to be introduced into the central housing (470) of one of the horizontal stringers (400 '), and the other part intended to be introduced into the central housing (470) of one of the vertical stringers (400).
    [0152]
    [0153] As shown in Figure 8, the first channel (430) for the arrangement of electrical elements has a guide (431) on one of its side walls for fixing an electrical power cable of the electrical elements.
    [0154]
    [0155] One of the horizontal stringers (400 '), which has the support feet (500) to the ground, has a lower housing (480) that is intended to receive retention means, which allows the support feet to be retained ( 500) with respect to the horizontal crossbar (400 ') preventing its movement.
    [0156]
    [0157] Additionally, each of the stringers (400,400 ’) has another rear housing (490) where anchoring means are inserted in case it is required to fix the light box to a wall or similar element.
    [0158]
    [0159] The light box does not require wiring to bring power to the LED panels (100). According to the invention, the passage of the power supply to the LED panels (100) is carried out using some of the LED panels (100) and the support pieces (600,800).
    [0160]
    [0161] As can be seen in figures 10, 11 and 12, the regions (610,810) of the first and second support pieces (600,800) have means for the passage of the power supply between the LED panels (100), while some of the LED panels (100) that are supported between the support pieces (600,800) have other means for the passage of the power supply between the support pieces (600,800).
    [0162]
    [0163] The means for the passage of the power supply of the LED panels (100) are shown in figures 11A and 11B, while the means for the passage of the feeding of the first and second pieces respectively are shown in figures 12A and 12B support (600,800).
    [0164]
    [0165] The LED panels (100) have a first electrical input connection (A) and a second electrical input connection (B) to receive the power supply, and a third electrical output connection (C) and a fourth electrical output connection (D) to send the power supply. One of the electrical input connections (A, B), preferably the first electrical input connection (A), is electrically connected to the panel LEDs (100) for their power supply.
    [0166]
    [0167] It is provided that the LEDs of the same LED panel (100) are electrically connected in series.
    [0168]
    [0169] The first support pieces (600) have a first electrical connection (A ’) and a second electrical connection (B’). The first electrical connection (A ') is configured to establish a quick electrical coupling with the first electrical input connection (A) of the LED panels (100) and the second electrical connection (B') is configured to establish a rapid electrical coupling with the second electrical input connection (B) of the LED panels (100).
    [0170]
    [0171] The electrical connections (A ’, B’) of the first support pieces (600) are arranged in one of the regions (610) that are used to support the corners of the LED panels (100).
    [0172]
    [0173] Specifically, the left region (610) of the first support pieces (600) has the electrical connections (A ', B'), so that said region performs a mechanical function for the support of one of the corners of one of the LED panels (100) and an electrical function for the electrical connection of the support piece (600) with the LED panel (100), while the right region (610) only performs a mechanical function for the support of one of the corners from another of the LED panels (100).
    [0174]
    [0175] In this way, the quick electrical coupling is obtained quickly and easily when the respective corner of the LED panel (100) is supported in the respective region (610) of the first support piece (600).
    [0176]
    [0177] The second support pieces (800) have a first electrical connection (A ''), a second electrical connection (B ''), a third electrical connection (C '') and a fourth electrical connection (D ''). The first and third connections (A '', C '') are electrically connected to each other, while the second and fourth connections (B '', D '') are also electrically connected to each other. Thus, the first electrical connection (A '') is configured to establish a quick electrical coupling with the third electrical output connection (C) of the LED panels (100), the second electrical connection (B '') is configured to establish a rapid electrical coupling with the fourth electrical output connection (D) of the LED panels (100), the third electrical connection (C '') is configured to establish a quick electrical coupling with the first electrical input connection (A) of the LED panels (100) and the fourth electrical connection (D '' ) is configured to establish a quick electrical coupling with the second electrical input connection (B) of the LED panels (100).
    [0178]
    [0179] The first and second electrical connections (A '', B '') of the second support pieces (800) are arranged in one of the regions (810) of the second support pieces (800) used for the support of one of the corners of one of the LED panels (100), while the third and fourth electrical connections (C '', D '') of the second support pieces (800) are arranged in another of the regions (810) of the second support pieces (800) that are used for the support of another of the corners of another of the LED panels (100).
    [0180]
    [0181] Specifically, the lower left region (810) of the second support pieces (800) has the first and second electrical connections (A '', B '') and the upper left region (810) has the third and fourth electrical connections ( C '', D ''), so that said regions (810) perform a mechanical function for the support of the LED panels (100) and an electrical function for the electrical connection of the second support piece (800) with the LED panels (100), while the upper and lower right regions (810) only perform a mechanical function to support the corners of the LED panels (100).
    [0182]
    [0183] In this way, as in the case of the first support pieces (600), the quick electrical coupling is obtained when the respective corners of the LED panel (100) are supported in the respective regions (810) of the second piece of support (800).
    [0184]
    [0185] Figures 11A, 11B and 11C show the means for the passage of the power supply of three embodiments of the LED panels (100).
    [0186]
    [0187] In the first embodiment of Figure 11A one of the LED panels (100) is shown in which a double passage of the power supply between the connections is established input (A, B) and output (C, D) of the LED panel (100). Thus, the first electrical input connection (A) and the third electrical output connection (C) of the LED panel (100) are connected by a first electrical line (L1), while the second electrical input connection (B) and The fourth electrical output connection (D) of the LED panel (100) is connected by a second power line (L2).
    [0188]
    [0189] As can be seen in Figure 10, the first power line (L1) receives power from a first power supply line (C1) and the second power line (L2) receives power from a second power supply line (C2).
    [0190]
    [0191] In the second embodiment of Figure 11B, another of the LED panels (100) is shown in which a single passage of the power supply is established between the input (A, B) and output (C, D) connections of the LED panel (100). Thus, the second electrical input connection (B) and the third electrical output connection (C) of the LED panel (100) are connected by a third electrical line (L3).
    [0192]
    [0193] In the third embodiment of Figure 11C another of the LED panels (100) is shown where no power supply passage is established between the input (A, B) and output (C, D) connections of the LED panel (100) In this case, only the LEDs are connected to the first input electrical connection (A) to receive the power supply.
    [0194]
    [0195] The electrical elements are arranged in the first channel (430) of the stringers (400, 400 ’). In the first channel (430) of the lower horizontal beam (400 ’) there are transformers (432) that are connected to the power grid by means of the power supply cable (shown in Figure 8). In the first channel (430) of at least one of the vertical stringers (400 ') a cable is provided internalized that carries the power supply from the lower horizontal stringer (400') to the upper horizontal stringer (400 '), where other transformers (432) are arranged.
    [0196]
    [0197] As can be seen in Figure 2, the LED panels (100) are arranged in vertical rows of LED panels (100), with at least one transformer (432) being provided for each of the rows of LED panels (100).
    [0198]
    [0199] Preferably two transformers (432) are used for the power supply of each of the rows of LED panels (100), each of the two transformers (432) being connected to one of the ends of the row of LED panels (100), so that the LED panels (100) of one end of the row are powered by one of the two transformers (432) and the LED panels (100) at the other end of the row are powered by the other transformer (432).
    [0200]
    [0201] The light boxes usually have high dimensions, for example 2 meters by 2 meters wide or even higher, as well as a large number of LEDs to be fed, for example in the light box of Figure 2 64 LED panels are arranged, each of them comprising 64 LEDs. Accordingly, it is particularly relevant to use two transformers (432) for each row of LED panels (100) so that there is no loss in the transmission of electrical energy, therefore, the transformers (432) of the lower horizontal stringer ( 400 ') are used to power the LED panels (100) of the lower part of the light box, while the transformers (432) of the upper horizontal beam (400') are used to power the LED panels (100) of the top of the light box.
    [0202]
    [0203] The transformers (432) are configured to transform the electrical voltage of the external network, generally 220V, to a voltage assimilable by the LED panels (100). It is planned to use transformers that convert the electrical input voltage from 220 V to 24 V, while each LED panel (100) has an additional transformer to transform the voltage value to a suitable value to power the LEDs, specifically the transformers additional convert the voltage from 24V to 5V. The transmission of the electrical voltage at 24 V to the LED panels (100) allows to reduce the loss of load and prevent problems of overheating in the power supply lines.
    [0204]
    [0205] According to the invention, the passage of control signals to command the LEDs for the representation of the images is also carried out using some of the LED panels themselves (100) and the support pieces (600,800). Accordingly, the regions (610,810) of the first and second support pieces (600,800) have means for the passage of the control signals between the LED panels (100), and some of the LED panels (100) have means for the passage of the control signals between the support pieces (600,800).
    [0206]
    [0207] According to all this, a possible non-limiting option for the transmission of energy The embodiment shown in Figures 10 and 13 is shown as electrical.
    [0208]
    [0209] From each of the transformers (432) the two power supply lines (C1, C2) leave, the first power supply line (C1) is connected to the first electrical connection (A ') of one of the first support pieces (600) of a first lower LED panel (100), and the second power supply line (C2) is connected to the second electrical connection (B ') of that first support piece (600). The first lower LED panel (100) is of the type shown in Figure 11A.
    [0210]
    [0211] In this way, the first electrical connection (A ') of the first support piece (600) establishes a rapid electrical coupling with the first electrical input connection (A) of the first LED panel (100) to receive the power supply of the first line (C1), while the second electrical connection (B ') of the first support piece (600) establishes a quick electrical coupling with the second electrical input connection (B) of the first LED panel (100) to receive the Second line power supply (C2). The LEDs of the first lower LED panel (100) are fed through the first input electrical connection (A).
    [0212]
    [0213] The current of the first power line (C1) is carried through the first power line (L1) of the first lower LED panel (100) to a second LED panel (100) immediately above the row, while through The second power line (L2) takes the current from the second power line (C2). In this case, the current of the first power line (C1) has already been used to power the first lower LED panel (100), but the current of the second power line (L2) has not been used.
    [0214]
    [0215] The second LED panel (100) immediately above is a panel as shown in Figure 11B. This second LED panel (100) is also fed with the current of the first power line (C1), while the third power line (L3) of the second LED panel (100) sends the current of the first power line (C1 ) towards a third LED panel (100) immediately above, which is an LED panel (100) as shown in Figure 11A, but whose second power line (L2) is in disuse, since the second LED panel (100) does not sends power to the second electrical connection (B) of the third LED panel (100).
    [0216]
    [0217] In this way, the first feed line (C1) is used to feed the two Bottom panels of a row of LED panels (100) of the light box, but the second power line (C2) is not used, but through the first power line (L1) of the first LED panel (100) and the third power line (L3) of the second LED panel (100), the current of the second power line (C2) is brought to the third LED panel (100) immediately above.
    [0218]
    [0219] The third power line (L3) of said second LED panel (100) makes a current branch of the second power line (C2) by allowing the connection of the second input connection (B) of the second LED panel (100) with the first input connection (A) of the third LED panel (100) immediately above, whereby said third upper panel is fed by the current of the second power line (C2).
    [0220]
    [0221] The first power line (L1) of said third LED panel (100) is used to bring the current from the second power line (C2) to a fourth LED panel (100) while the second power line (L2) is inoperative.
    [0222]
    [0223] In this way, the first and second LED panels (100) of a row are fed with the current of the first power line (C1), while the third and fourth LED panels (100) of the row are fed by the first power line (C1). The other four panels of the row that are arranged above are fed in the same way but by two other power lines that leave a transformer located in the upper horizontal stringer (400 ') of the light box, as it is see in figure 13.
    [0224]
    [0225] The quick electrical coupling between the LED panels (100) and the support parts (800) is carried out as explained above.
