[0041] The following describes the embodiments of the present invention in detail, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. Figures 1 to 9 The described embodiments are exemplary and are intended to be used to explain the embodiments of the present invention, but should not be construed as limiting the present invention.

[0042] In the description of the embodiments of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0043] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0044] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0045] In one embodiment of the present invention, Figures 1 to 3 As shown, a spliced ​​luminous sign 1000 is provided, including a light guide plate 10, a control board 20, a reflective layer 30, an external terminal 40 and a plurality of light sources 50. The light guide plate 10 may preferably be a transparent structure. The control board 20 is generally a PCB board. The external terminal 40 may be a female terminal or a male terminal, such as a Type-C interface, a USB interface, a micro USB interface, etc. The light source 50 may be an LED.

[0046] Furthermore, the light guide plate 10 is divided into a plurality of light guide portions 11. The light guide plate 10 may be a whole plate structure, and the plurality of light guide portions 11 are defined by area division (for example Figure 2 As shown). Alternatively, a plurality of light guide portions 11 may be physically connected to form the entire light guide plate 10. That is, the light guide portion 11 itself also belongs to the plate structure. In this way, the light guide portion 11 itself has a front side and a back side. Among them, a reflective layer 30 is provided on at least one front side or back side of each light guide portion 11. For example, a reflective layer 30 may be provided on the front side of the light guide portion 11, a reflective layer 30 may be provided on the back side, or a light guide layer may be provided on both the front side and the back side, and the arrangement is performed according to actual needs.

[0047] Furthermore, combined with Figure 2As shown, the side of the light guide 11 is provided with an incident portion 12 for incident light to enter. The side of the light guide 11 is the side facing the side of the control board 20. The incident portion 12 may be a part of the structure of the light guide 11 itself, for example, the side between two adjacent light guides 11 may be used as the incident portion 12. The incident portion 12 preferably adopts a stepped structure, so that it can provide a space to avoid the side end of the corresponding position of the light source 50 and / or the control board 20.

[0048] Each light source 50 is electrically connected to the control board 20 , and each light source 50 emits incident light into the light guide portion 11 through the corresponding incident portion 12 and propagates therein until the incident light hits the reflective layer 30 to make the reflective layer 30 illuminate.

[0049] Specifically, Figure 2 , 4 As shown in 5, an anti-cross-light groove 13 is provided between two adjacent light guide parts 11 by means of a perforated hole on the light guide plate 10 of the whole plate structure. The setting of the anti-cross-light groove 13 forms a gap between two adjacent light guide parts 11. When the incident light emitted by the light source 50 is irradiated into the light guide part 11 through the incident part 12 and propagates therein, the light between the adjacent light guide parts 11 can be prevented from forming cross-light.

[0050] In other embodiments, the incident portion 12 may also be externally connected to the side of the light guide portion 11 facing the control board 20 .

[0051] Combination Figure 2 As shown, the light guide 11, the light reflective layer 30 disposed thereon, and the corresponding light source 50 constitute a light emitting unit 100, that is, a light reflective layer 30 is disposed on the front and / or back of each light guide 11, and at least one light source 50 emits light into the light guide 11, so that the light guide 11, the light reflective layer 30, and the light source 50 in the corresponding relationship constitute a light emitting unit 100. In other words, in a setting mode, at least one light reflective layer 30 is disposed on each light guide 11, and at least one light source 50 is matched, so that the light guide 11, the light reflective layer 30, and the light source 50 form a corresponding relationship and constitute an independent light emitting unit 100. It can also be understood that each light emitting unit 100 has at least one light emitting layer 30 and at least one light source 50. In this way, a plurality of light emitting units 100 can be formed, and each light emitting unit 100 is arranged in a ring shape. That is, there are multiple light emitting units 100, and the multiple light emitting units 100 are arranged in a ring, wherein the definition of the ring should be a non-closed ring, for example, a semi-ring.

[0052] Among them, Figure 2As shown, since the incident portion 12 of the light-emitting unit 100 is arranged on the side of the light-guiding portion 11, the side is the side facing the control board 20. The side of the light-guiding portion 11 can also be designed to be stepped, providing space for the installation of other components, and combined with the setting mode of projecting light from the side, the thickness of the light-guiding plate 10 can be effectively reduced, thereby reducing the overall thickness of the spliced ​​light-emitting sign 1000, which is conducive to the light and thin design of the spliced ​​light-emitting sign 1000 of this embodiment.

[0053] The external terminal 40 in this embodiment is electrically connected to the control board 20, and the external terminal 40 is used to realize communication and power supply when multiple spliced ​​luminous signs 1000 are spliced. That is, multiple spliced ​​luminous signs 1000 in this embodiment can be spliced, and each spliced ​​luminous sign 1000 can be powered on and transmit signals through the external terminals 40 connected to each other, that is, communication and power supply.

[0054] The following is a further description of the spliced ​​luminous sign 1000 provided in the embodiment of the utility model: the spliced ​​luminous sign 1000 provided in the embodiment of the utility model divides the light guide plate 10 into a plurality of light guide parts 11, so that a reflective layer 30 and an incident part 12 can be set on each light guide part 11, and then the light source 50 electrically connected to the control board 20 is matched with the incident part 12, so that the incident light emitted by the light source 50 is irradiated into each light guide part 11 of the light guide plate 10 through the incident part 12 set on the light guide part 11 of the light guide plate 10, and the light propagates in each light guide part 11 of the light guide plate 10 until the incident light irradiates the reflective layer 30 set on each light guide part 11. Layer 30 makes the reflective layer 30 glow, then the corresponding light guiding parts 11, each reflective layer 30 and each light source 50 constitute a light-emitting unit 100 respectively, and each light-emitting unit 100 is arranged in a ring shape. The ring arrangement can make the electronic control part concentrated in the center part for unified setting, which greatly improves the integration of the circuit, effectively reduces the cost of product production and the simplicity of design, and finally, by splicing multiple spliced ​​light-emitting signs 1000, the desired pattern formed by the combination of the light-emitting units 100 is obtained. The light-emitting pattern has a high degree of freedom, which makes the spliced ​​light-emitting sign 1000 of the utility model more applicable to a wider range of scenarios and greatly improves its fun of use.

[0055] Among them, the light-emitting units 100 arranged in a ring can share a control system (the control system can be a control board 20, or a main control board connected to the control board 20), thereby achieving diversified light emission and greatly reducing production costs.

[0056] In another embodiment of the present invention, Figures 4-5As shown, each light-emitting unit 100 is arranged radially with the control board 20 as the center. In addition, each light-emitting unit 100 surrounds the periphery of the control board 20. In this way, the control board 20 is arranged in the center or substantially in the center of each light-emitting unit 100. The layout of the light-emitting unit 100 in this embodiment realizes a setting mode in which the light-guiding portion 11 and the light-emitting units 100 formed by it surround the control board 20 with the control board 20 as the center. In this way, the light-emitting units 100 can be arranged around the control board 20, so that one control board 20 controls multiple light-emitting units 100. This is conducive to the splicing setting of multiple spliced ​​light-emitting signs 1000.

[0057] In another embodiment of the present invention, Figure 2 and 5 As shown, the spliced ​​luminous sign 1000 also includes a central light guide block 90 and a central light source 110. The number of central light sources 110 can be one or more. For example, the number of central light sources 110 can also be the same as the number of light sources 50 in the above embodiment. The central light guide block 90 is arranged in the middle of each of the light guide parts 11, and the light guide parts 11 are arranged in a ring. Among them, the central light source 110 is electrically connected to the control board 20. The central light source 110 irradiates the incident light emitted into the central light guide block 90 and propagates therein. The central light guide block 90 and the central light source 110 together constitute a central light-emitting unit 200. That is, the light emitted by the central light source 110 enters the central light guide block 90 and propagates therein. At this time, the light of the central light source 110 is inwardly directed, and the light is in the middle or center of the entire spliced ​​luminous sign 1000. Different from the above embodiment in which the light emitting units 100 are arranged in a ring, the light generated by the light source 50 is emitted outward, and the light of this structure is located at the periphery (i.e., the ring position) of the entire spliced ​​light emitting sign 1000. Of course, the light emitting units 100 and the central light emitting unit 200 in the above embodiment can share a control board 20.

[0058] It should be noted that: Figure 3 The illustration is an example that the number of central light sources 110 is the same as the number of light sources 50, and they are arranged back-to-back in a one-to-one correspondence. In other embodiments, there can be only one central light source 110, for example, arranged in the middle of the control panel 20, or at any side. That is, the utility model does not limit the number of central light sources 110.

[0059] Furthermore, the central light source 110 and the light source 50 may be configured to emit light of different colors.

[0060] Furthermore, the outer end of the central light guide block 90 is provided with a plurality of radially arranged inlay portions 91, such as Figure 2 As shown, each embedded portion 91 can be adapted to be embedded in the anti-cross-light groove 13 .

[0061] In another embodiment of the present invention, Figures 1-2 As shown, each light emitting unit 100 arranged around the periphery of the control board 20 is formed with a notch 101. Generally, the notch 101 is formed by the space between two adjacent light emitting units 100. More specifically, the notch 101 is formed by the space between the outer end surfaces of two adjacent light emitting units 100. The outer end of each light emitting unit 100 away from the control board 20 forms a convex portion 102. For example, the light emitting units 100 are arranged radially with the control board 20 as the center, and then they have an outer end extending away from the control board 20, and the outer end forms the convex portion 102. In this embodiment, the notch 101 and the convex portion 102 are referenced to the previous embodiment.

[0062] Furthermore, the notch portion 101 and / or the convex portion 102 are provided with an external terminal 40 (refer to Figure 1 ). External terminals 40 may be provided on all or part of the recessed portions 101 formed between the light-emitting units 100. Similarly, external terminals 40 may be provided on all or part of the protruding portions 102 on each light-emitting unit 100. The shape of the protruding portion 102 can match the shape of the recessed portion 101, and through the adaptation of one protruding portion 102 and one recessed portion 101, the corresponding two external terminals 40 can be plugged into each other, thereby enabling multiple spliced ​​light-emitting signs 1000 to be spliced ​​with each other. Specifically, when a recessed portion 101 and a protruding portion 102 of two spliced ​​light-emitting signs 1000 are docked, as long as there are corresponding external terminals 40 on both, the plug-in splicing of the two can be achieved. Such a design can make the splicing of the spliced ​​luminous sign 1000 provided in this embodiment very flexible and diversified in style. In this way, the light-emitting unit 100 formed by adaptation can emit light effects with different patterns and effects, and has a wider range of applicable scenes. Whether it is used as a game, a toy or a lamp, it can greatly improve its fun. In addition, the embedded assembly of the notch portion 101 and the convex portion 102 makes the splicing between the two more firm and stable.

[0063] Furthermore, combined with Figures 6 to 8 As shown, the design of the notch 101 and the convex portion 102 of the spliced ​​luminous sign 1000 of the present invention can perfectly splice multiple spliced ​​luminous signs 1000 together to obtain the required game, toy or lamp decoration area and shape.

[0064] Moreover, the spliced ​​luminous sign 1000 of the utility model can also realize intelligent interactive control of communication and conduction between multiple spliced ​​luminous signs 1000; therefore, an external terminal 40 for communicating and powering the control board 20 is provided on the recessed portion 101 and the convex portion 102, and the external terminal can be a male head or a female head.

[0065] In another embodiment of the present invention, Figure 4 As shown, the spliced ​​luminous sign 1000 also includes a conductive layer 60, which is stacked on at least one front or back surface of each light guide portion 11. Specifically, for example, the conductive layer 60 and the reflective layer 30 can be simultaneously arranged on the front, back, or both of the light guide portion 11, or the conductive layer 60 and the reflective layer 30 can be respectively arranged on the front and back surfaces of the light guide portion 11. The conductive layer 60, the light guide portion 11, and the reflective layer 30 can be stacked. Each conductive layer 60 is electrically connected to the control board 20 and forms a touch unit respectively. The conductive ink layer can be formed by printing, the metal foil layer can be connected by soldering, and the wire can be connected by bonding. It should be pointed out that the stacking arrangement in this embodiment includes at least four situations, which are arranged in the order of the light guiding part 11, the light reflecting layer 30, and the conductive layer 60; or arranged in the order of the light guiding part 11, the conductive layer 60, and the light reflecting layer 30; or arranged in the order of the conductive layer 60, the light guiding part 11, and the light reflecting layer 30 (respectively arranged on different surfaces); or the conductive layer 60 and the light reflecting layer 30 are independently and non-overlappingly arranged in different areas on the front or back of the light guiding part 11. In this way, the formation of the touch unit can be achieved. Of course, the conductive layer 60 can also be first covered on other central carriers, and then the central carrier can be stacked on the light guiding part 11 of the light guiding plate 10. The central carrier can adopt a transparent film structure, for example. Among them, the conductive layer 60 is one of a conductive ink layer, a metal foil layer, and a wire. For example, in this embodiment Figure 6 The conductive layer 60 in the embodiment is a conductive ink layer.

[0066] like Figure 2 As shown, the present invention may further include a separator 80 , and the conductive layer 60 may be printed on the separator 80 . The separator 80 may adopt a film structure or a sheet structure, for example.

[0067] In another embodiment of the present invention, Figures 4-5As shown, the reflective layer 30 is a conductive layer, which is electrically connected to the control board 20 and forms a touch unit (not shown), and the conductive layer 60 is one of a conductive ink layer, a metal foil layer, and a wire. The conductive ink layer can be formed by printing, the metal foil layer can be connected by soldering, and the wire can be connected by bonding. In this embodiment, the reflective layer 30 is directly set as a conductive layer, and the reflective layer 30 is made of a conductive material. The reflective layer 30 can be used as the conductive layer of this embodiment. For example, the reflective layer 30 can be made of conductive ink or metal foil. The overall structure of the light-emitting unit 100 is greatly simplified, which is conducive to the lightweight design of the spliced ​​light-emitting sign 1000 of this embodiment.

[0068] For another example, a reflective layer 30 and a conductive layer 60 are disposed on the light guide portion 11 of the light guide plate 10. The conductive layer 60 may be a metal foil layer or a conductive ink layer. A conductive ink layer may be directly or indirectly disposed on the light guide portion 11. The so-called indirect arrangement means that the conductive layer 60 (e.g., the conductive ink layer and / or the reflective layer 30) is first disposed on a central carrier, for example, Figure 2 On the separator 90 shown as a partition, the partition as a layer structure can be a film, a sheet, etc., and then the central carrier is set on the light guide plate 10; further, the conductive ink can be printed into a required shape to achieve a decorative effect; the conductive ink layer is connected to the gold finger 21 on the control board 20, so that an extended display effect can be achieved.

[0069] The spliced ​​luminous sign 1000 of this embodiment can be made interesting by changing the capacitance of the conductive ink layer, i.e., changing the capacitance of the conductive layer 60, when the human body touches the luminous sign. After receiving the signal of capacitance change, the control chip in the control board 20 controls the light source 50 according to a preset program, such as changing color or turning on and off the light, so as to achieve an interactive effect of controlling the light source 50 by touching the conductive ink layer, which has an interesting and interactive decorative effect. Furthermore, the light source 50 can also be intelligently controlled according to the fixed hardware address of the light source 50 and the conductive layer 60 or the hardware.

[0070] In another embodiment of the present invention, Figures 1-2As shown, the light source 50 corresponding to each light-emitting unit 100 is controlled by a fixed control unit, and the control unit is a different chip or a different chip pin. Specifically, the spliced ​​light-emitting board 1000 of this embodiment has a fixed shape, and a plurality of light-emitting units 100 and a plurality of touch units are formed in a fixed area of ​​the spliced ​​light-emitting board 1000, and further form a fixed combination of a one-to-one correspondence. In this way, a plurality of spliced ​​light-emitting boards 1000 can be spliced ​​and electrically connected in different shapes, and light-emitting control models of different shapes can be combined through hardware address recognition to achieve unified and coordinated interactive control and improve the fun of use.

[0071] Furthermore, the touch control unit is also controlled by a fixed control unit. Similarly, the control unit is a different chip or different chip pins.

[0072] Among them, Figure 3 As shown, the light source 50 is preferably disposed on the control panel 20. Figure 2 The external connection terminal 40 shown in the figure is connected to the control board 20 in the figure.

[0073] In another embodiment of the present invention, Figures 1-2 As shown, the external terminals 40 provided on the recessed portion 101 and each convex portion 102 are provided with different control ports for ID identification and communication, and the control ports are different chips or different chip pins. Specifically, the module shape of multiple fixed spliced ​​luminous signs 1000 spliced ​​together by different external terminals 40 is unique. Since the external terminals 40 are provided with different control ports, the control ports are used for ID identification and communication, and the control ports are different chips or different chip pins. In this way, the light-emitting unit 100 and the touch unit inside the spliced ​​luminous sign 1000 are a fixed combination and have different control ports. Therefore, it is only necessary to send the hardware connection combination data to the host computer (such as the APP of the mobile terminal or the software program of the computer terminal) through the control board 20, and a control model with an appearance consistent with the actual spliced ​​appearance can be established on the host computer. The control program written on the host computer can be downloaded to the control board 20 through the wireless module on the control board 20 or the external terminal 40, so as to realize the functions of various interactive games and finally realize unified and coordinated interactive control. See Fig. 9 As shown, a mobile terminal 2000 or a computer terminal 3000 can be used to establish a control model having an appearance consistent with the appearance formed by actually splicing each spliced ​​luminous sign 1000.

[0074] In another embodiment of the present invention, the reflective layer 30 completely covers or partially covers the front or back surface of the light guide portion 11; the reflective layer 30 is a frosted layer formed by physically carving on the surface of the light guide portion 11, or a conductive ink layer formed by printing on the surface of the light guide portion 11. The reflective layer 30 can cover the light guide portion 11 of the light guide plate 10 completely or partially (e.g., Figure 4 As shown in the figure, the surface covering the light guide portion 11 can be the front side or the back side. In this way, the display effect of the light-emitting unit 100 can be diversified. For example, the desired decorative pattern can be obtained by partial covering, that is, the desired pattern can be directly pasted or drawn to form the reflective layer 30, and a luminous pattern of a specific shape can be obtained after the light source 50 emits light, achieving the desired decorative effect, which is very interesting.

[0075] Furthermore, the reflective layer 30 is physically carved directly on the surface of the light guide portion 11 to form a frosted surface effect. The reflective layer 30 is either translucent or opaque, and since the incident light can partially pass through the light guide portion 11, the light guide portion 11 can shine, and at the same time, the incident light is reflected in different directions, so that the light guide portion 11 can be seen shining from all angles.

[0076] In another embodiment of the present invention, the incident portion 12 is at least one of a flat mirror, a convex lens, and a concave lens. However, the incident portion 12 of this embodiment is not limited thereto.

[0077] In another embodiment of the present invention, the incident portion 12 is integrally formed with the light guide portion 11, wherein a surface of the incident portion 12 close to the light source 50 is at least one of a flat surface, a convex surface, and a concave surface. However, the present invention does not limit the incident portion 12 to only the above structures.

[0078] The spliced ​​luminous sign 1000 of the present invention uses a flat mirror, a convex lens or a concave lens as the incident part 12, which has a good light guiding effect. The incident part 12 can also be set according to the light transmission requirements of different display patterns, so that the spliced ​​luminous sign 1000 of the present invention can display a wider range of patterns.

[0079] In another embodiment of the present invention, Figure 2As shown, the spliced ​​luminous sign 1000 also includes a bottom cover 70, the light guide plate 10 and the bottom cover 70 are mutually covered and connected, and the control board 20 is located between the bottom cover 70 and the light guide plate 10. The bottom cover 70 in this embodiment can be a flat structure or a shell structure with a cavity of a certain depth, which can be connected to the light guide plate 10, for example, the light guide plate 10 is buckled on the bottom cover 70, or the bottom cover 70 is buckled on the light guide plate 10, and connected by a physical connection. In this way, the bottom cover 70 can work together with the light guide plate 10 to protect the components between them.

[0080] The bottom cover 70 is made of a hard material or a flexible material, for example, the bottom cover 70 can be a plastic shell, a plastic plate, a paper shell, or a cardboard.

[0081] Preferably, the shape of the bottom cover 70 matches the shape of the light guide plate 10 .

[0082] In another embodiment of the present invention, Figures 6 to 8 As shown, a luminous card set is provided, including at least spliced ​​luminous cards 1000, two adjacent spliced ​​luminous cards 1000 are matched and plugged in and electrically connected through the external terminals 40 thereon to achieve assembly to form a fixed shape.

[0083] Specifically, the external terminals 40 at fixed positions between the light-emitting units 100 of the spliced ​​light-emitting sign 1000 are spliced, and the spliced ​​appearance is also fixed. Each light-emitting unit 100 and the touch unit on the spliced ​​light-emitting sign 1000 are also fixed. In addition, the hardware address of the external terminal 40 is also fixed, and the communication control model after the assembly is also fixed. The communication module of the spliced ​​light-emitting sign 1000 uploads these fixed data to the host computer, and the control model of different assembly combinations can be realized. In this way, this control model can realize the systematic control of each light-emitting unit 100 of the spliced ​​light-emitting sign 1000.

[0084] Furthermore, if Figure 8 As shown, the outer ends of the light-emitting units 100 formed by the light guide plate 10 in the spliced ​​light-emitting sign 1000 in this embodiment have a plurality of regular edges a.

[0085] For example, the light emitting unit 100 has three regular sides a, and the convex portion 102 is formed by the three regular sides a; for another example, the light emitting unit 100 has four regular sides a, and the convex portion 102 is formed by the four regular sides a.

[0086] For example, the notch 101 can be formed by surrounding two adjacent sides a of two adjacent light-emitting units 100. In this way, the butt joint between the sides a of the light-emitting units 100 on two different spliced ​​light-emitting signs 1000 can achieve the adaptation of the corresponding convex part 102 and the notch 101, so that any spliced ​​light-emitting sign 1000 can be spliced ​​with multiple spliced ​​light-emitting signs 1000 at the same time. When the number of spliced ​​light-emitting signs 1000 is sufficient, they can be spliced ​​into a light-emitting sign set of a desired shape and pattern.

[0087] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
