Description

Technical Field

[0001] This application relates to the field of light strings, and more particularly to a full matrix light string system, a control method, a serial data transmission method, and a control circuit for functional devices. Background Technology

[0002] Traditional curtain matrix light strings use a simple parallel structure of "one control for many". The control box outputs three main lines: positive, negative, and signal line. These three lines are connected in parallel to each branch circuit through multiple T-junctions. All branch circuits are connected to the main lines with exactly the same electrical relationship, resulting in completely identical signals received by each branch. When controlled via a mobile app, only synchronous changes of all branches can be achieved; independent programming of the light emitters at any position in the matrix is ​​not possible, and fine patterns or dynamic effects cannot be created.

[0003] To achieve point-to-point control, the industry mainly adopts the following two technical approaches, but both have obvious drawbacks: Address code scheme: A unique hardware address code (such as an ID embedded in a DIP switch or chip) is programmed into each light-emitting unit (such as an LED bead or integrated module). The controller broadcasts data frames containing instructions corresponding to all addresses. Each light-emitting unit extracts and executes its own proprietary instructions by parsing the data packets and matching them with its own address code. A significant drawback of this scheme is that the address code correspondence must be strictly managed in all aspects of production, warehousing, installation, and maintenance; if any unit is damaged, a spare part with the exact same address code must be used for replacement, resulting in a complete lack of interchangeability between components, leading to high maintenance costs and poor flexibility.

[0004] Hub-based branching scheme: The system uses a multi-port hub. Each physical branch (typically consisting of multiple LEDs cascaded via serial communication) is connected as a whole to an independent port of the hub. The hub is responsible for distributing the total data flow from the controller to each branch port. While this scheme enables point control, it introduces an additional core active component—the hub—which not only increases the overall system cost and wiring complexity but also introduces the risk of single-point failure. Furthermore, the system's scalability is limited by the inherent number of ports on the hub.

[0005] In summary, existing technical solutions struggle to achieve high precision and flexible point control while simultaneously ensuring a simple system architecture, ease of installation and maintenance, high interchangeability of components, and controllable costs. Therefore, the market urgently needs an innovative technical solution that can address these issues concurrently. Summary of the Invention

[0006] Purpose of the Invention: The purpose of this invention is to overcome the aforementioned shortcomings of existing technologies and propose a novel matrix-type LED string control solution. This solution aims to completely eliminate the dependence on hardware address codes and achieve precise, independent control of each light-emitting unit in a large-scale LED string matrix without the need for a hub. Simultaneously, this invention strives to make the system simple in structure, low in cost, extremely convenient in installation and maintenance, with all units of the same specification being fully interchangeable, and possessing good scalability and reliability.

[0007] This application provides a full matrix light string system, including: a controller, multiple light-emitting units, a main circuit and M branches, M≥2, the main circuit is connected to the controller, the main circuit supplies power to at least one branch, each branch is provided with at least one light-emitting unit, and the M branches include a first branch and a second branch. The controller is used to output serial data packets, and the serial data packets it sends are input to the first branch. The output signal of at least one light-emitting unit in the first branch is used as the input signal of the first light-emitting unit in the second branch.

[0008] Beneficial effects: Therefore, in the embodiments of this application, the light-emitting units in each branch can transmit control data serially, and the control data between each branch can be transmitted serially. The light-emitting units of the light string can extract their own data streams. Independent control of the light-emitting units in the light string can be achieved without address codes and hubs.

[0009] Serial data packets first flow into the first branch, where all the light-emitting units sequentially intercept and consume the data stream belonging to that branch. The last light-emitting unit in the first branch forwards the remaining serial data packets and uses them as input signals to the second branch, repeating the process. This relay continues until all the light-emitting units in all branches have finished processing. Throughout the process, the serial data packets flow sequentially along a unidirectional "data pipeline," with each light-emitting unit only taking its own data stream. This achieves independent control of each light-emitting unit in the matrix, eliminating the need for address codes and hubs, resulting in an extremely simple system architecture.

[0010] This application transforms the traditional parallel signal path into a serial path based on "forward signal transmission and backward signal return". By introducing an independent signal return line in each branch and using the connecting node as a smart tee to realize signal switching between branches, the physical M×N matrix is ​​logically transformed into a series light string with M×N nodes, thus achieving precise addressing and control solely based on the position sequence.

Detailed Implementation

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0035] In this document, references to "embodiment" or "implementation" mean that a particular feature, structure, or characteristic described in connection with an embodiment or implementation may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0036] like Figure 1 and Figure 2 As shown, the full matrix light string system 10, or simply light string 10, includes a controller 500, multiple light-emitting units 300, a main circuit 200, and M branch circuits 100, where M ≥ 2. Figure 1 The diagram illustrates that the light string 10 includes four branches 100. This application does not limit the number of branches 100; for example, the number of branches 100 can also be 2, 3, 5, 8, 10, 15, 20, or 100. The main circuit 200 is connected to the controller 500. It is understood that the wiring and / or components on the main circuit 200 are physically and electrically connected to the controller 500. The main circuit 200 supplies power to at least one branch 100. It is understood that the wiring on the main circuit 200 can supply power to at least one branch 100; in one case, the main circuit can supply power to M branches 100; in another case, the main circuit 200 supplies power to one or some of the M branches 100, while one or some of the M branches 100 are supplied by other wiring. Each branch 100 is provided with at least one light-emitting unit 300, and the M branches 100 include a first branch 110 and a second branch 120. The controller 500 is used to output serial data packets, and the serial data packets it sends are input to the first branch 110. The output signal of at least one light-emitting unit 300 in the first branch 110 is used as the input signal of the first light-emitting unit 300A in the second branch 120.

[0037] It is understood that the output signal of the light-emitting unit 300 in the first branch 100 originates from a serial data packet, and the input signal of the first light-emitting unit 300A in the second branch 120 also originates from a serial data packet. For example, the serial data packet issued by the controller 500 of this application contains control data for controlling all light-emitting units 300.

[0038] Therefore, in the embodiments of this application, the light-emitting units in each branch 100 can transmit control data serially, and the control data between each branch 100 can transmit control data serially. The light-emitting units 300 of the light string 10 can extract their own data streams. Without address codes and hubs, independent control of the light-emitting units 300 in the light string 10 can be achieved.

[0039] For example, at least one light-emitting unit 300 of branch M 100 is configured to: receive a data stream (which may be referred to as data, signal, or instruction) from a serial data packet of the previous node, extract its own control data (which may be referred to as control signal or control instruction), and then forward the remaining data stream in the serial data packet to the next node. The previous node may be a controller 500, the previous light-emitting unit 300 in the same branch 100, or the end light-emitting unit 300B in the previous branch 100. The next node may be the next light-emitting unit 300 in the same branch, or the first light-emitting unit 300A in the next branch 100. It is understood that after extracting the necessary control data, the light-emitting unit 300 also uses this control data to drive the light-emitting element in the light-emitting unit 300.

[0040] At least one light-emitting unit 300 in the first branch 110 receives a data stream (which may be referred to as data or a signal) from a serial data packet from the controller 500, extracts its own control data (which may be referred to as a control signal), and then forwards the remaining data stream in the serial data packet, such as to the first light-emitting unit 300A in the second branch 120, as an input signal to the first light-emitting unit 300A in the second branch 120. For example, the output signal of the last light-emitting unit 300B in the first branch 110 is input to the first light-emitting unit 300A in the second branch 120 as its input signal. In other optional embodiments, the output signals of other light-emitting units 300 in the first branch 110, such as the first light-emitting unit 300A, are input to the next node light-emitting unit 300 in the first branch 110, and the output signals of other light-emitting units 300 in the first branch 110 are also input to the first light-emitting unit 300A in the next branch 100, such as the second branch 120.

[0041] Exemplarily, the string of lights 10 further includes N branches 100, where N≥2 and N<M. The N branches 100 are powered by the main road 200. Each of the N branches 100 is provided with at least one light-emitting unit 300. For any two adjacent branches 100 among the N branches 100, the output signal of the last light-emitting unit 300B in the Xth branch 130 serves as the input signal of the first light-emitting unit 300A in the Yth branch 140, where N is greater than or equal to 2, and the Yth branch is the next branch of the Xth branch. The Xth branch 130 can be referred to as the third branch 130, and the Yth branch 140 can be referred to as the fourth branch 140. It can be understood that one light-emitting unit 300 can be provided in any branch 100, or multiple light-emitting units 300 can be provided. For example, the first branch 110, the second branch 120, and the third branch 130 are all provided with multiple light-emitting units 300. For another example, the fourth branch 140 is provided with one light-emitting unit 300, and the light-emitting unit 300 in the fourth branch 140 serves as the first light-emitting unit at the head end of the fourth branch 140 and also as the last light-emitting unit at the end of the fourth branch 140. When multiple light-emitting units 300 are provided in any branch 100, the multiple light-emitting units 300 in that branch 100 are connected in series.

[0042] In an optional embodiment, the number of light-emitting units 300 in the first branch 110 is multiple and they are connected in series, and the number of light-emitting units 300 in the second branch 120 is multiple and they are connected in series. In an optional embodiment, the number of light-emitting units 300 in the first branch 110 is multiple and they are connected in series, and the number of light-emitting units 300 in the second branch 120 is one. In an optional embodiment, the number of light-emitting units 300 in the first branch 110 is one, and the number of light-emitting units 300 in the second branch (120) is multiple and they are connected in series.

[0043] As Figure 2 and Figure 3 shown, the method for controlling the string of lights 10 in the embodiment of the present application includes: step 011 and step 012.

[0044] Step 011: The controller 500 generates a serial data packet containing control data for all light-emitting units 300 in a preset order.

[0045] Step 012: Control the serial data packet to enter the first branch 110 and the second branch 120 in sequence. It can be understood that the first branch 110 is the upper branch of the second branch 120.

[0046] As Figure 2 and Figure 4 shown, step 012 includes step 0121 and step 0122.

[0047] Step 0121: The serial data packet is transmitted to at least one light-emitting unit 300 in the first branch 110. At least one light-emitting unit 300 in the first branch 110 extracts a portion of the data, that is, at least one light-emitting unit 300 in the first branch 110 extracts the control data it needs. For example, the serial data packet first enters the first light-emitting unit 300 of the first branch 110, that is, the first-end light-emitting unit 300A. After the first-end light-emitting unit 300A takes away its own data at the beginning of the serial data packet, it forwards the remaining data to the next light-emitting unit 300 of the first branch 110, until the last light-emitting unit 300 of the first branch 110, that is, the last light-emitting unit 300B.

[0048] Step 0122: At the predetermined return point of the first branch 110, the remaining data of the serial data packet is transmitted back to the main branch 200 and enters the second branch 120 as input data. The predetermined return point of the first branch 110 may be the signal output terminal of the end light-emitting unit 300B of the first branch 110.

[0049] For example, the light string 10 also includes at least one connection node 400. At a predetermined return point of the first branch 110, the remaining data of the serial data packet is returned to one of the connection nodes 400, transmitted through the internal wiring of the connection node 400 to the second branch 120, and enters the second branch 120 as input data.

[0050] After step 011 and before step 012, the control method for the light string 10 may further include: the controller 500 sending a serial data packet to the main line 200, and then the main line 200 transmitting the serial data packet to the first branch 100 of each branch 100, such as the first branch 110. For example, a connection node 400 of the main line 200 first transmits the serial data packet to the first branch 100, such as the first branch 110.

[0051] In step 0122, the predetermined return point of the first branch 110, such as the signal output terminal of the end light-emitting unit 300 in the first branch 110, transmits the remaining data of the serial data packet back to another connection node 400 of the main branch 200. The other connection node 400 transmits the remaining data of the serial data packet to the second branch 120 and uses it as input data. Each light-emitting unit 300 in the second branch 120 repeats the above process of extracting its own data and forwarding it to the next light-emitting unit 300 until the end light-emitting unit 300B transmits the remaining data back to the next connection node 400 of the main branch 200. Then, the next connection node 400 transmits the remaining data to the next branch 100, and so on until the last branch 100.

[0052] like Figure 2 and Figure 5As shown, the control method for the light string 10 in this embodiment includes: Step 021: The controller 500 sends a serial data packet to the first connection node 400 of the main line 200. Prior to step 021, the controller 500 generates a serial data packet containing control data for all light-emitting units 300 in a preset order.

[0053] Step 022: The first connection node 400 of the main road 200 transmits the serial data packet to the first branch 100, i.e., the first branch 110.

[0054] Step 023: The first light-emitting unit 300A in the first branch 110 receives the serial data packet and extracts its own control data.

[0055] Step 024: The first light-emitting unit 300A in the first branch 110 drives the light-emitting element of the first light-emitting unit 300A according to its extracted self-control data, and serially transmits the remaining data to the next light-emitting unit 300 in the first branch 110 until the end light-emitting unit 300B.

[0056] Step 025: After the end light-emitting unit 300B in the first branch 110 extracts its own control data, it drives the light-emitting element of the end light-emitting unit 300B and sends the remaining data of the serial data packet back to the second connection node 400 of the main branch 200.

[0057] Step 026: The second connection node 400 of the main road 200 transmits the remaining data from the first branch 110 to the second branch 120 as the input signal of the second branch 120. Each light-emitting unit 300 of the second branch 120 cyclically executes steps 023, 024 and 025.

[0058] It can be understood that after the end light-emitting unit 300B of the second branch 120 extracts its own control data, it drives the light-emitting element of the end light-emitting unit 300B and sends the remaining data of the serial data packet back to the third connection node 400 of the main branch 200. This process is repeated until the last branch 100.

[0059] like Figure 1 and Figure 2 , combined Figure 3 , Figure 4 and Figure 5 The following section uses four branches as an example to explain in detail the data transmission process of the serial data packets sent by the controller 500: The controller 500 sends a serial data packet to the first connection node 400 of the main branch 200. Before sending the serial data packet, the controller 500 generates a serial data packet containing control data of all light-emitting units 300 in a preset order. Then, the first connection node 400 of the main branch 200 transmits the serial data packet to the first branch 100, i.e., the first branch 110. Then, the first light-emitting unit 300A in the first branch 110 receives the serial data packet and extracts its own control data. The first light-emitting unit 300A in the first branch drives its light-emitting element to light up according to the extracted control data, and serially transmits the remaining data to the next light-emitting unit 300 in the first branch 110. The next light-emitting unit 300 in the first branch 110 extracts its own control data and drives its light-emitting element to light up according to the extracted control data, and serially transmits the remaining data to the next light-emitting unit 300 in the first branch 110, such as the end light-emitting unit 300B. The end light-emitting unit 300B extracts its own control data and drives its light-emitting element to light up according to the extracted control data, and sends the remaining data back to the second connection node 400 of the main road 200. Then, the second connection node 400 transmits the remaining data to the second branch 120. In the second branch 120, the first-end light-emitting unit 300A extracts its own control data from the received data stream, drives its light-emitting element to light up, and forwards the remaining data in the serial data packet to the next light-emitting unit 300 in the second branch 120, such as the last light-emitting unit 300B. The last light-emitting unit 300B extracts its own control data from the received data stream, drives its light-emitting element to light up, and forwards the remaining data in the serial data packet to the next light-emitting unit 300 in the second branch 120, such as the last light-emitting unit 300B. The remaining data in the data packet is sent back to the third connection node 400 of the main path 200. The first connection node 400 transmits the remaining data to the third branch 130. The light-emitting unit 300 in the third branch 130 cycles through the light-emitting unit 300 in the second branch 120 and then transmits the remaining data back to the fourth connection node 400 of the main path 200. The fourth connection node 400 transmits the remaining data to the next branch 100, such as the fourth branch 140. The light-emitting unit 300 in the fourth branch 140 cycles through the light-emitting unit 300 in the second branch 120 and then transmits the remaining data back to the main path 200.

[0060] In this embodiment, the serial data packet first flows into the first branch 110. All light-emitting units 300 in the first branch 110 sequentially intercept and consume the data stream belonging to that branch 110. The last light-emitting unit 300B in the first branch 110 forwards the remaining data and uses it as an input signal into the second branch 120, repeating the above process. This relay continues until all light-emitting units 300 in all branches 100 have finished processing. Throughout the process, the serial data packet flows sequentially along a unidirectional "data pipeline," with each light-emitting unit 300 only taking its own data stream. This achieves independent control of each light-emitting unit 300 in the matrix, without the need for address codes and hubs, resulting in a very simple system architecture. This application transforms the traditional parallel signal path into a serial path based on "forward signal transmission and backward signal return," thereby achieving precise addressing and control based on positional order.

[0061] For example, such as Figures 6-8 As shown, Figures 6-8 The circuit diagram of the light string 10 in one optional embodiment of this application is shown, wherein the various branches 100 of the light string 10 are arranged in parallel, such as the first branch 110, the second branch 120, the third branch 130, and the fourth branch 140. Each branch 100 of the light string 10 is physically connected to the main circuit 200. The signal lines of each branch 100 and the signal lines 211 of the main circuit 200 are transmitted in series, for example, the signal lines 211 of the main circuit 200, the signal lines 111 of the first branch 110, and the signal lines 121 of the second branch 120 are transmitted in series. The power supply lines of each branch 100 are connected in parallel, for example, the power supply line 112 of the first branch 110 and the power supply line 122 of the second branch 120 are connected in parallel. Furthermore, the power supply lines of each branch 100 are electrically connected to the power supply line 212 of the main road 200, so that the power supply line 212 of the main road 200 can supply power to the power supply lines of each branch 100. For example, the power supply line 212 of the main road 200 is electrically connected to the power supply line 112 of the first branch 110 and the power supply line 122 of the second branch 120, respectively, and can supply power to the first branch 110 and the second branch 120.

[0062] The controller 500 has its power output terminal electrically connected to the power supply line 212 of the main circuit 200, and its signal output terminal electrically connected to the signal line 211 of the main circuit 200. That is, the controller 500's output terminals include both a power output terminal and a signal output terminal. The controller 500's input terminals can be electrically connected to a power supply via an electrical connection interface, such as mains power, a solar panel, or a rechargeable battery. Control signals issued by the controller 500, such as serial data packets, can be transmitted through the controller 500's signal output terminal to the signal line 211 of the main circuit 200, and then transmitted through the main circuit 200's signal line 211 to the first branch 100, such as the first branch 110. Figure 7 As shown, Figure 7 The transmission path L of the serial data packet is shown, illustrating the transmission process of the serial data packet in the light string 10.

[0063] It is understood that the light-emitting unit 300 on each branch 100 is installed on the power supply line 112 and signal line 111 of each branch 100. The power supply line 112 of each branch 100 can supply power to each light-emitting unit 300, and the signal line 111 of each branch 100 can transmit control signals to drive the light-emitting element of the light-emitting unit 300.

[0064] For example, in this embodiment of the application, the signal lines 111 of each branch 100 include a signal transmission line 1111 and a signal return line 1112 connected in series. The signal input line 1111 of a predetermined branch 100, such as the first branch 110, is connected in series with the signal return line 1112 of the predetermined branch 100, such as the first branch 110, and the signal return line 1112 of the predetermined branch 100, such as the first branch 110, is connected in series with the signal input line 1211 of its next branch 100, such as the second branch 120. Similarly, the signal input line 1211 of the second branch 120 and the signal return line 1212 of the second branch 120 are connected in series. Furthermore, the signal input lines and signal return lines of two adjacent branches 100 are connected in series through the lines on the main road 200. For example, the signal return line 1112 of the first branch 110 is electrically connected to the signal line 211 of the main road 200, and the signal input line 1211 of the second branch 120 is electrically connected to the signal line 211 of the main road 200.

[0065] For example, the power supply line 212 of the main line 200 includes at least a first polarity line 2121 and a second polarity line 2122. The first polarity line 2121 and the second polarity line 2122 transmit signals with opposite polarities; for example, the first polarity line 2121 transmits a positive electrical signal, and the second polarity line 2122 transmits a negative electrical signal. Similarly, the power supply lines of each branch line 100 include a first polarity line and a second polarity line. For example, the power supply line 112 of the first branch line 110 includes a first polarity line 1121 and a second polarity line 1122, and the power supply line 122 of the second branch line 120 includes a first polarity line 1221 and a second polarity line 1222. The first polarity line 1121 and the first polarity line 1221 are both electrically connected to the first polarity line 2121 and are arranged in parallel. The second polarity line 1122 and the second polarity line 1222 are both electrically connected to the second polarity line 2122 and are arranged in parallel.

[0066] For example, such as Figures 6-10 As shown, each light-emitting unit 300 includes a signal processing circuit 311 and a signal return channel 312. The output signal of at least one light-emitting unit 300 in the first branch 110 is transmitted to the signal processing circuit 311 of the first light-emitting unit 300A in the second branch 120 via the signal return channel 312 of that light-emitting unit 300 and serves as its input signal. For example, the signal return channel 312 is independently configured relative to the signal processing circuit 311, that is, each light-emitting unit 300 includes a signal processing circuit 311 and an independent signal return channel 312. The signal processing circuit 311 includes a signal input terminal 3111 and a signal output terminal 3112. The signal return channel 312 includes a signal return input terminal 3121 and a signal return output terminal 3122 that are directly electrically connected. The signal processing circuit 311 is used to receive the data stream from the serial data packet from the signal input terminal 3111, extract its own control data, and then forward the remaining data in the serial data packet from the signal output terminal 3112. For example, the signal return channel 312 of each light-emitting unit 300 includes a signal return line 3213. The signal return line 3213 is independent of the signal processing circuit 311. That is, the signal return line 3213 of a certain light-emitting unit 300 is isolated and insulated from the signal processing circuit 311 of that light-emitting unit 300. This channel does not perform any data processing and only provides a low-impedance signal path. It should be further noted that the signal output terminal 3112 of the signal processing circuit 311 of one of the light-emitting units 300 in a certain branch 100, such as the end light-emitting unit 300B, is electrically connected to the signal return input terminal 3121 of the signal return channel 312.

[0067] Each light-emitting unit 300 also includes a power supply circuit 313, which is electrically connected to the power supply line of its respective branch 100. Furthermore, the power supply circuit 313 of the first light-emitting unit 300A is electrically connected to the power supply line 212 of the main branch 200. For example, the power supply circuit 313 of each light-emitting unit 300 includes a first polarity input terminal 3131, a second polarity input terminal 3132, a first polarity output terminal 3133, and a second polarity output terminal 3134. Some light-emitting units 300 have their first polarity input terminals 3131 electrically connected to the first polarity line 2121 of the main circuit 200, and some light-emitting units 300 have their second polarity input terminals 3132 electrically connected to the second polarity line 2122 of the main circuit 200; the first polarity output terminal 3133 of each light-emitting unit 300 is electrically connected to the first polarity input terminal 3131 of the next light-emitting unit 300 in its branch 100 or to the first polarity input terminal 3131 of the next branch 100; the second polarity output terminal 3134 of each light-emitting unit 300 is electrically connected to the second polarity input terminal 3132 of the next light-emitting unit 300 in its branch 100 or to the second polarity input terminal 3132 of the next branch 100, until the last light-emitting unit 300 of the last branch 100 of the light string 10.

[0068] For example, such as Figures 6-10 As shown, the signal flow direction F1 formed by the signal input terminal 3111 and the signal output terminal 3112 of any light-emitting unit 300 in any branch 100, such as the first branch 110, is opposite to the signal flow direction F2 formed by the signal return input terminal 3121 and the signal return output terminal 3122 in the signal return channel 312.

[0069] For example, in each branch 100, such as the first branch 110 or the second branch 120, the signal output terminal 3112 of the signal processing circuit 311 of the end light-emitting unit 300B is electrically connected to the signal return input terminal 3121 of the corresponding signal return channel 312. Figure 10 As shown, for example, the signal output terminal 3112 of the signal processing circuit 311 of the end light-emitting unit 300B is shorted to the signal return input terminal 3121 of the corresponding signal return channel 312 to form a common port structure 314. In other optional embodiments, the signal output terminal 3112 of the signal processing circuit 311 of the end light-emitting unit 300B and the signal return input terminal 3121 of the corresponding signal return channel 312 can be electrically connected by wires or solder joints such as solder. It should be noted that... Figure 9 The light-emitting unit 300 shown can be the first light-emitting unit 300A, or it can be another light-emitting unit 300 located between the first light-emitting unit 300A and the last light-emitting unit 300B. Figure 9When the signal output terminal 3112 of the signal processing circuit 311 of the light-emitting unit 300 shown is electrically connected to the signal return input terminal 3121 of the corresponding signal return channel 312 through wires or solder joints such as solder, it can be used as the end light-emitting unit 300B.

[0070] For example, such as Figures 6-8 The full-matrix light string system in various embodiments of this application is assembled from modular components and is scalable. These modular components include, for example, a modularly designed controller 500, which can be plugged into and detached from other components such as connection nodes 400 to achieve physical and electrical connections. The modular components also include modularly designed light-emitting units 300, each of which can be assembled or disassembled. The number of light-emitting units 300 in each branch 100 can be expanded as needed to achieve physical and electrical connections between the light-emitting units 300 in a single branch 100. Furthermore, the modular components include modularly designed connection nodes 400. On the main road 200, the number of connection nodes 400 can be expanded as needed, with one connection node 400 connecting to a branch 100. For example, in this application, the number of connection nodes 400 is equal to the number of branches 100. The connection relationship of the connection node 400 will be illustrated by way of example in conjunction with the circuit diagram of the connection node 400. Then, the modular components of this application will be illustrated by way of example in conjunction with the structural diagram of the controller 500, the structural diagram of the connection node 400 and the structural diagram of the light-emitting unit 300.

[0071] like Figure 1 , Figures 6-8 ,and Figure 11 The light string 10 also includes at least two connection nodes 400. Each connection node 400 includes a first main signal terminal 411, a second main signal terminal 421, a branch signal input terminal 431, and a branch signal return terminal 432. The internal wiring of the connection node 400 is configured to guide the signal arriving at the first main signal terminal 411 to the branch signal input terminal 431, and to guide the signal arriving at the branch signal return terminal 432 to the second main signal terminal 421; the signal here originates from a serial data packet. Furthermore, there is no direct signal path between the first main signal terminal 411 and the second main signal terminal 421. The internal wiring of the connection node 400 is also configured to prevent the signal from being transmitted directly from the first main signal terminal 411 to the second main signal terminal 421 without passing through the first branch 110.

[0072] Inside the connection node 400, the first main signal terminal 411 is directly electrically connected to the branch signal input terminal 431, and the branch signal return terminal 432 is directly electrically connected to the second main signal terminal 421. (Combined) Figure 9 and Figure 10The first main signal terminal 411 and the branch signal input terminal 431 are directly electrically connected via a wire such as signal input line 445, and the branch signal return terminal 432 and the second main signal terminal 421 are directly electrically connected via a wire such as signal return line 446. Signal input line 445 generates signal flow F1 during signal transmission, and signal return line 446 generates signal flow F2 during signal transmission.

[0073] The connection node 400 also includes a set of power input terminals and two sets of power output terminals. For example, the power input terminals of the connection node 400 include a first polarity power input terminal 413 and a second polarity power input terminal 414, and the power output terminals of the connection node 400 include a first polarity power output terminal 423, a second polarity power output terminal 424, a first polarity power output terminal 433, and a second polarity power output terminal 434. Specifically, the first polarity power input terminal 413 is electrically connected to the first polarity line 2121 of the power supply line 212 in the main circuit 200, and specifically, the first polarity power input terminal 413 is electrically connected to the first polarity power output terminal of the controller 500 through the first polarity line 2121 of the power supply line 212 in the main circuit 200. The second polarity power supply input terminal 414 is electrically connected to the second polarity line 2122 of the power supply line 212 in the main circuit 200. Specifically, the second polarity power supply input terminal 414 is electrically connected to the second polarity power supply output terminal of the controller 500 through the second polarity line 2122 of the power supply line 212 in the main circuit 200. The first polarity power supply output terminal 423 is electrically connected to the first polarity power supply input terminal 413 of the next connection node 400, and the second polarity power supply output terminal 424 is electrically connected to the second polarity power supply input terminal 414 of the next connection node 400. The first polarity power supply output terminal 433 is electrically connected to the first polarity line 1121 of the power supply line 112 in a branch circuit 100, such as the first branch circuit 110, and the second polarity power supply output terminal 434 is electrically connected to the second polarity line 1122 of the power supply line 112 in a branch circuit 100, such as the first branch circuit 110. It is understood that the first polarity power supply output terminal 433 is electrically connected to the first polarity input terminal 3131 of the first light-emitting unit 300A in a branch 100, and the second polarity power supply output terminal 434 is electrically connected to the second polarity input terminal 3132 of the first light-emitting unit 300A in a branch 100. Inside the connection node 400, the first polarity power supply input terminal 413 is electrically connected to the first polarity power supply output terminal 433 via a wire such as power supply line 441, and the first polarity power supply input terminal 413 is electrically connected to the first polarity power supply output terminal 423 via a wire such as power supply line 444. The second polarity power supply input terminal 414 is electrically connected to the second polarity power supply output terminal 434 via a wire such as power supply line 442, and the second polarity power supply input terminal 414 is electrically connected to the second polarity power supply output terminal 424 via a wire such as power supply line 444. Thus, the first connecting node 400 in the main road 200 can supply power to the first branch 100, such as the first branch 110, and can supply power to other connecting nodes 400 on the main road 200.

[0074] like Figure 12 , Figure 13 and Figure 14 As shown, Figure 12This diagram illustrates a structural configuration of the light string 10A in one optional embodiment of this application. Figure 13 Figure 12 is a diagram illustrating the modular design of each component in the light string 10A. Figure 14 This is to illustrate one structure of the light string 10B in another alternative embodiment of this application. (In conjunction with...) Figure 15 For example, both ends of the controller 500 are connected to electrical connection interfaces. Specifically, the input end of the controller 500 is connected to the first electrical connection interface 510, and the output end of the controller 500 is connected to the second electrical connection interface 520. The first electrical connection interface 510 includes a first polarity power supply input terminal 513 and a second polarity power supply input terminal 514, both of which can be connected to a power supply. The first electrical connection interface 510 may also include a thread 515, which can be provided on the inner surface of an insulating component, such as a plastic component, of the first electrical connection interface 510. This first electrical connection interface 510 can be rotated and plugged into other components, such as power plugs or transformer components, to achieve physical and electrical connections. The second electrical connection interface 520 includes a signal input terminal 521, a first polarity power supply output terminal 523, and a second polarity power supply output terminal 524. The second electrical connection interface 520 also includes a thread 525, which may be provided on the outer surface of an insulating component, such as a plastic component, of the second electrical connection interface 520.

[0075] Combination Figure 16For example, connection node 400 is a tee connector module. For example, the first main signal terminal 411 and the second main signal terminal 421 are respectively formed as electrical connection interfaces (410, 420) for pluggable connection with other connector modules, and the branch signal input terminal 431 and the branch signal return terminal 432 together form an electrical connection interface 430 for pluggable connection with other connector modules. Specifically, the first main signal terminal 411, the first polarity power supply input terminal, and the second polarity power supply input terminal form an electrical connection interface 410, and the electrical connection interface 410 and the second electrical connection interface 520 are physically and electrically connected. Specifically, the electrical connection interface 410 also includes a thread 415, which can be provided on the inner surface of an insulating component, such as a plastic component, of the electrical connection interface 410. The threads 415 of the electrical connection interface 410 and the threads 525 of the second electrical connection interface 520 can be helically connected and helically separated. The first main signal terminal 411 and the signal input terminal 521 are electrically connected, the first polarity power supply output terminal 523 and the first polarity power supply input terminal 413 are electrically connected, and the second polarity power supply output terminal 524 and the second polarity power supply input terminal 414 are electrically connected. The second main signal terminal 421, the first polarity power supply output terminal 423, and the second polarity power supply output terminal 424 form an electrical connection interface 420. The electrical connection interface 420 also includes a thread 425, and the thread 415 can be provided on the outer surface of the insulating part, such as a plastic part, of the electrical connection interface 420. The electrical connection interface 420 can be physically and electrically connected to the electrical connection interface 410 of the next connection node 400 through plug-in connection. The electrical connection interface 420 of the current connection node 400 and the electrical connection interface 410 of the next connection node 400 are connected and disconnected through the helix of the thread 425 and the thread 415. The second main signal terminal 421 is electrically connected to the first main signal terminal 411 of the electrical connection interface 410 of the next connection node 400. The first polarity power supply output terminal 423 is electrically connected to the first polarity power supply input terminal 413 of the electrical connection interface 410 of the next connection node 400. The second polarity power supply output terminal 424 is electrically connected to the second polarity power supply input terminal 412 of the electrical connection interface 410 of the next connection node 400. The branch signal input terminal 431, the branch signal return terminal 432, the first polarity power supply output terminal 433, and the second polarity power supply output terminal 434 form an electrical connection interface 430. The electrical connection interface 430 also includes a thread 435, which can be provided on the outer surface of the insulating component, such as a plastic component, of the electrical connection interface 430.

[0076] For example, the electrical connection interfaces (410, 420, 430) are multi-pin female connectors, multi-pin male connectors, or coaxial rotary connectors.

[0077] Combination Figure 17 , Figure 19 , Figure 20 , Figures 23-26The light-emitting unit 300, such as the first-end light-emitting unit 300A, includes a pluggable electrical connection interface (352, or 360), and the electrical connection interface (352, or 360) includes electrical connection terminals (352A or 362A). The light-emitting unit 300 also includes a light-emitting element 330 and one or more pluggable electrical connection terminals 370 electrically connected to the light-emitting element 330. The electrical connection terminals 370 and the electrical connection terminals (352, or 360) are pluggable and pluggable. The electrical connection terminals (352A, 362A, 370) are coaxial rotary connectors, and the positive and negative terminals of the electrical connection terminals (352A, 362A, 370) are coaxially arranged.

[0078] For example, the light-emitting unit 300, such as the first-end light-emitting unit 300A, includes an electrical connector module 350 and a light-emitting component 301. The electrical connector module 350 includes a pluggable electrical connection interface 351 and an electrical connection interface 352; the electrical connection interface 351 and the electrical connection interface 430 are pluggable and pluggable. Specifically, the electrical connection interface 351 includes a signal input terminal 3511, a signal return output terminal 3512, a first polarity power supply input terminal 3513, and a second polarity power supply input terminal 3514. The electrical connection interface 351 also includes a thread 352, which can be provided on the inner surface of an insulating component, such as a plastic component, of the electrical connection interface 351. The thread 352 of the electrical connection structure 351 and the thread 435 of the electrical connection interface 430 can be screwed together and separated to achieve a rotary pluggable connection. Branch signal input terminal 431 and signal input terminal 3511 are electrically connected; signal return output terminal 3512 and branch signal return terminal 432 are electrically connected; first polarity power supply input terminal 3513 and first polarity power supply output terminal 433 are electrically connected; and second polarity power supply input terminal 3514 and second polarity power supply output terminal 434 are electrically connected. Electrical connection interface 352 includes electrical connection terminal 352A and a thread 3525 disposed on its outer periphery. Electrical connection terminal 352A includes signal output terminal 3521, signal return input terminal 3522, first polarity power supply output terminal 3523, and second polarity power supply output terminal 3524. The thread 3525 may be disposed on the outer surface of an insulating component, such as a plastic component, of electrical connection interface 352. Inside the electrical connector module 350, signal input terminal 3511 and signal output terminal 3521 are electrically connected, signal return input terminal 3522 and signal return output terminal 3512 are electrically connected, first polarity power supply input terminal 3513 and first polarity power supply output terminal 3523 are electrically connected, and second polarity power supply output terminal 3524 and second polarity power supply input terminal 3514 are electrically connected. The electrical connection terminal 352A and the electrical connection terminal 370 of the light-emitting component 301 are pluggable, such as a rotatable pluggable connection, meaning that the electrical connection terminal 352A and the electrical connection terminal 370 can be plugged into and separated from each other, and can rotate relative to each other during or after plugging.

[0079] For example, the light-emitting component 301 may include a first circuit board 310, a signal processing circuit 311, and a signal return channel 312 disposed on the first circuit board 310. For example, the light-emitting unit 300 includes a second circuit board 320, which surrounds the first circuit board 310, and the first and second circuit boards 320 are electrically connected. For example, the light-emitting component 301 further includes a carrier 390, which surrounds the first circuit board 310 and serves as a support for the second circuit board 320, which is made of a flexible material. For example, the light-emitting component 301 further includes a light-emitting element 330 disposed on the second circuit board 320. For example, the light-emitting component 301 includes one or more electrical connection terminals 370; this embodiment of the application uses two electrical connection terminals 370 as an example.

[0080] Combination Figure 18 and Figure 21 The difference between the light-emitting component 302 of the end light-emitting unit 300B and the light-emitting component 301 of the beginning light-emitting unit 300A includes that the light-emitting component 302 of the end light-emitting unit 300B includes an electrical connection terminal 370. It should be noted that when a branch 100 is provided with only one light-emitting unit 300, the light-emitting unit 300 of that branch 100 can refer to... Figure 18 The light-emitting unit 300B shown and Figure 21 The light-emitting components 302 shown will not be described in detail here. It should also be noted that when the number of light-emitting units 300 in a branch 100 is greater than three, the light-emitting unit 300 located between the first light-emitting unit 300A and the last light-emitting unit 300B in that branch 100 may include two electrical connection interfaces 360, but not... Figure 17 Electrical connection interface 351 in the electrical connector module 350 shown.

[0081] For example, the electrical connection terminals (352A, 362A, 370) are coaxial rotary connectors, with the positive and negative terminals of electrical connection terminals (352A, 362A, 370) arranged coaxially. The electrical connection terminals of electrical connection terminals 362A and 370 can be referenced to electrical connection terminal 352A, and will not be described individually here. Electrical connection terminals 352A and 370 can be inserted and disconnected, and can rotate relative to each other after insertion or during insertion. Electrical connection terminals 362A and 370 can be inserted and disconnected, and can rotate relative to each other after insertion or during insertion.

[0082] The light-emitting unit 300 also includes a lampshade 340, which has at least one opening 341 and a thread 342 at the opening 341. The electrical connection interface 352 of the first-end light-emitting unit 300A in the branch 100 has a thread 3525 on its outer periphery, which mates with the thread 342 at the opening 341 of the lampshade 340 to achieve a connection and fixation between the electrical connection interface 352 and the lampshade 340. For example, the lampshade 340A of the first-end light-emitting unit 300A includes a first opening 341A and a second opening 341B, and includes a first thread 342A and a second thread 342B. The thread 3525 of the electrical connection interface 352 and the first thread 342A at the first opening 341A of the lampshade 340A can be screwed together and separated. The light-emitting component 301 is disposed within the cavity 343 of the lampshade 340A and can be inserted into or removed from the cavity 343 through any opening 341. The thread 3625 of the electrical connection interface 360 ​​and the second thread 342B at the second opening 341B of the lampshade 340A can be screwed together and separated. For example, the lampshade 340B of the end-emitting 300B includes an opening 341 and a thread 342 disposed at the opening 341, and the thread 3625 of the electrical connection interface 360 ​​and the thread 342 at the opening 341 of the lampshade 340B can be screwed together and separated.

[0083] Combination Figures 21-24 The assembly process of each modular component in the light string 10 is as follows: Assembly process of each modular component in the light string 10: Connect the electrical connection interface 520 of the output end of the controller 500 and the electrical connection interface 410 of the connection node 400. Specifically, if the electrical connection interface 520 is kept stationary, drive the electrical connection interface 410 to rotate in the rotation direction D1 with the user's finger to complete the connection between the electrical connection interface 520 and the electrical connection interface 410, that is, to realize the physical and electrical connection between the two.

[0084] Assembly process of each modular component in the light string 10, step two: Connect the electrical connection interface 430 of the connection node 400 to the electrical connection interface 351 of the connector module 350 of the electrical head end light-emitting unit 300A. Specifically, if the electrical connection interface 430 is kept stationary, drive the electrical connection interface 351 to rotate in the direction of rotation D2, such as by the user using their finger, to complete the connection between the electrical connection interface 430 and the electrical connection interface 351, that is, to achieve the physical and electrical connection between the two.

[0085] Assembly process of each modular component in the light string 10: Connect the light-emitting component 301 of the first light-emitting unit 300A to the electrical connection interface 352 of the electrical connection module 350. Specifically, the electrical connection terminal 352A of the electrical connection interface 352 and one electrical connection terminal 370 of the light-emitting component 301 can be directly plugged in to achieve physical and electrical connection.

[0086] Assembly process of each modular component in the light string 10, step four: Insert the light-emitting component 301 into the cavity 343 of the lamp cover 340A from an opening 341, such as the first opening 341A, of the lamp cover 340A of the first light-emitting unit 300A. Then, keeping the electrical connection terminal 352A stationary, drive the lamp cover 340A to rotate in the rotation direction D3, as if driven by the user with their finger, so as to connect the first thread 342A of the lamp cover 340A and the thread 3525 of the electrical connection interface 352.

[0087] Assembly process of each modular component in the light string 10, step five: Align the electrical connection terminal 362 of the electrical connection interface 360 ​​with another opening 341 of the lamp cover 340A, such as the second opening 341B, and align it with another electrical connection terminal 370 in the light-emitting component 301. Then, keep the lamp cover 340B from rotating, and drive the electrical connection interface 360 ​​to rotate in the rotation direction D4, such as by the user using their finger, so as to connect the second thread 342B of the lamp cover 340B and the thread 3625 of the electrical connection interface 360 ​​in a spiral connection. Before or during the spiral connection, the electrical connection terminal 370 and the electrical connection terminal 362 are inserted to achieve electrical connection.

[0088] It is understandable that the other light-emitting units 300 in the branch 100 are assembled with reference to the assembly process of the first light-emitting unit 300A until the last light-emitting unit 300 is reached. Then the assembly of the next connection node 400 and the assembly of the next branch are started, which will not be described in detail here.

[0089] The connection relationship between electrical connection interface 360 ​​and lampshade 340, and the connection relationship between electrical connection interface 352 and lampshade 340, are not limited to threaded connections. Other optional embodiments, such as Figure 27 As shown, the lampshade 340C and the electrical connection interface 360C of the light-emitting unit 300C are connected by a locking component 380, such as a screw.

[0092] By introducing an independent signal return line in each branch 100 and using a smart tee as a connection node 400 to realize signal switching between branches 100, the physical M×N matrix is ​​logically transformed into a series light string with M×N nodes, so that precise addressing and control can be achieved solely by relying on the position sequence.

Step 052: After the main trunk, the remaining data is transmitted to the first device of the Y branch; wherein the Y branch and the X branch are adjacent, and the Y branch is the next branch of the X branch; Step 061: If there are other devices on the X branch, the first device on the X branch obtains the required data from the serial data packet and transmits the remaining data to the other devices on the X branch until the last device on the X branch.
