These linear light groups typically consist of a fixed number of LEDs. Considering the needs of users in different scenarios, modular linear light groups have emerged. However, because the number of LEDs in a modular linear light group can change according to user requirements, it is difficult to determine whether newly added LEDs are effectively connected to the circuit, making it challenging to obtain the actual number of LEDs connected in the modular linear light group.

[0018] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0019] To enable those skilled in the art to better understand the solutions of this application, 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. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0020] In splicable linear light-emitting modules, since the light-emitting units basically communicate in one direction, when a light-emitting unit sends a signal to the next light-emitting unit, it is impossible to determine whether the signal it sent to the next light-emitting unit is valid, and it is also impossible to determine whether the next light-emitting unit has been connected to the light-emitting module. This makes it difficult to detect the number of light-emitting units in the light-emitting module.

[0021] Currently, some light-emitting modules have light-emitting units equipped with microcontroller units (MCUs). This allows communication between MCUs to determine the presence of light-emitting units and thus detect their quantity. However, equipping each light-emitting unit with an MCU would significantly increase product costs, which is detrimental to production and sales.

[0022] To address the aforementioned issues, the inventors, after extensive research, proposed a detection method for the light-emitting module provided in the embodiments of this application. This method applies the detection of static current to the determination of the number of light-emitting units, which not only solves the difficulty in determining the number of light-emitting units but also reduces the detection cost.

[0023] The hardware environment of the detection method for the light-emitting module involved in this application will be introduced below.

[0024] like Figure 1 As shown, the detection method for the light-emitting module provided in this application embodiment can be applied to... Figure 1 The light-emitting module circuit 500 shown includes a detection resistor 501 and an interface circuit 503. The interface circuit 503 may include multiple parallel interface branches 5031, such as a first interface branch 502. Figure 2As shown, the light-emitting module circuit 500 may include a light source module 505, which includes multiple light-emitting units 5051, such as a first light-emitting unit 504. An interface branch 5031 is adapted to connect to the light-emitting units 5051 to supply power to them. The light-emitting module circuit 500 may also include a controller 507, which controls the power-on and power-off of each interface branch 5031. In one embodiment, the controller can be connected to multiple light-emitting units in the light source module via a serial signal line 506, and the controller can send on / off operation commands to the control chip of the light-emitting unit via the serial signal line 506.

[0025] For example, when the controller sends a lamp-off command to the control chips of all light-emitting units via the serial signal line, the control chips of all light-emitting units can power off all light-emitting units through the interface branch. It should be noted that after powering off all interface branches, since the control chips of all light-emitting units still have a base current, this base current can be taken as the quiescent current of the light source module. Knowing the resistance value of the sensing resistor, after measuring the voltage V across the sensing resistor, the current through the sensing resistor, i.e., the quiescent current of the light source module, can be calculated according to Ohm's law. This quiescent current can then be taken as the base current.

[0026] In some embodiments, the current I passing through the detection resistor 501 can be obtained, and the first interface branch 502 can be powered on while the other interface branches 5031 besides the first interface branch 502 can be powered off. At this time, the current I1 passing through the detection resistor 501 can be obtained. If the first interface branch 502 is connected to the light-emitting unit, that is, the first light-emitting unit 504, then I1>I. Thus, the difference in current of the detection resistor 501 before and after the interface branch is powered on / off can be used to determine whether the light-emitting unit is connected to the light-emitting module circuit.

[0027] It is worth noting that, in this embodiment, the power-off / power-on of the interface branch should be understood as: power-off / power-on of only one / specified interface branch in the interface circuit while the entire light-emitting module circuit is conducting. Furthermore, the interface of the interface circuit can be a physical plug-in interface, the two ends of which can be connected to the entire light-emitting module circuit via wires. Connecting the light-emitting module circuit to the light-emitting unit only requires electrically connecting the light-emitting unit to the interface, such as through the plug-in relationship between pins and sockets.

[0028] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0029] Please see Figure 3 , Figure 3An embodiment of this application illustrates a method for detecting a light-emitting module, which may include the following steps S110 to S170.

[0030] Step S110: Obtain the reference current. The reference current is used to characterize the static current of the detection resistor when all interface branches are in a de-energized state controlled by the controller.

[0031] During use, users can dynamically adjust the number of light-emitting units in the splicable linear light-emitting module according to the needs of the actual application scenario. In order to obtain the number of light-emitting units in real time, the change of current in the light-emitting module circuit can be used to determine whether the light-emitting unit is connected to the light-emitting module circuit, and thus obtain the number of light-emitting units.

[0032] The reference current should be understood as the static current measured by the detection resistor when all interface branches in the light-emitting module are in a de-energized state. When all interface branches in the light-emitting module are in a de-energized state, interface branch A in the interface circuit can be powered on. If interface branch A is connected to the light-emitting component, the current in the light-emitting module circuit will change.

[0033] As one implementation method, given the resistance value of the detection resistor, the voltage across the detection resistor can be obtained to calculate the current flowing through the detection resistor. When all interface branches are in a de-energized state, the voltage across the detection resistor can be obtained, and the static current flowing through the detection resistor can then be calculated.

[0034] For example, the controller in the light-emitting module can control the power-off of all interface branches. At this time, the controller can obtain the voltage U across the sensing resistor. Given the resistance value R of the sensing resistor, the static current of the sensing resistor can be calculated according to Ohm's law.

[0035] Step S130: Determine the target interface branch among multiple interface branches. The target interface branch is the interface branch to be tested in the interface circuit.

[0036] Among them, the target light-emitting interface branch refers to the interface branch that needs to be determined whether to connect to the light-emitting unit. The target interface branch can be randomly selected in the interface circuit or a specified interface branch. The current change of the light-emitting module circuit can be caused by controlling the power-on / power-off state of the target interface branch, thereby determining whether the target interface branch is connected to the light-emitting unit.

[0037] In one implementation, each interface branch can be sequentially identified as a target interface branch according to the order of the interface branches in the light-emitting module. In another implementation, a compromise can be made by sequentially identifying the interface branch located in the middle of the interface circuit as the target interface branch, thereby improving the efficiency of detecting whether the light-emitting unit is connected to the light-emitting module circuit.

[0038] Step S150: Power on the target interface branch and obtain the target detection current. The target detection current is used to characterize the current of the detection resistor when the target interface branch is powered on and the other interface branches among the multiple interface branches are powered off.

[0039] After powering off all interface circuits, in order to determine whether the target interface branch is connected to the light-emitting unit, only the target interface branch in the interface circuit can be powered on to obtain the current of the detection resistor, and then the current of the detection resistor can be compared with the reference current to determine whether the target interface branch is connected to the light-emitting unit.

[0040] As one implementation method, the target interface branch can be powered on, while the other interface branches in the interface circuit can be powered off. Furthermore, the current voltage across the detection resistor can be obtained, and then the current through the detection resistor under the current voltage, i.e., the target detection current, can be calculated.

[0041] Step S170: Based on the reference current and the target detection current, perform access detection on the target interface branch to obtain the detection result; wherein, the access detection is used to detect whether the target interface branch is connected to the light-emitting unit.

[0042] The access detection of the target interface branch refers to detecting whether the target interface branch is connected to the light-emitting unit. By performing access detection on all interface branches in the interface circuit, the detection results can include whether the target interface branch is connected to the light-emitting unit and whether the target interface branch is not connected to the light-emitting unit. Then, based on the access detection results of each interface branch, the number of light-emitting units connected in the light-emitting module can be obtained.

[0043] As one implementation method, the difference between the target detection current and the reference current can be used to determine whether the target interface branch is connected to the light-emitting unit. Optionally, when the target interface branch is detected to be connected to the light-emitting unit, the number of light-emitting units can be incremented by 1. For example, the controller creates a variable n to represent the number of light-emitting units. After initializing the variable n, if it is determined that the target interface branch is connected to the light-emitting unit, the variable n is incremented by 1, which can be recorded as n = n + 1. If it is determined that the target interface branch is not connected to the light-emitting unit, the variable n is not processed.

[0044] In this embodiment, a reference current is obtained to determine the target interface branch among multiple interface branches, and a target detection current is obtained. Further, based on the reference current and the target detection current, an access detection is performed on the target interface branch to obtain a detection result. This access detection is used to detect whether the target interface branch is connected to a light-emitting unit. Thus, the presence of a light-emitting unit is detected by using the change in current in the light-emitting module, and the number of light-emitting units in the light-emitting module can be calculated based on the detection result.

[0045] like Figure 4 As shown, Figure 4 This illustration schematically shows another detection method for a light-emitting module provided in an embodiment of the present application. The detection method for the light-emitting module may include the following steps S210 to S270.

[0046] To detect the presence of a light-emitting unit by measuring the change in current within the light-emitting module, after acquiring a reference current, the target interface branch can be sequentially activated to acquire a target detection current. Then, the presence of the light-emitting unit can be determined based on the change in current within the light-emitting module circuit. In some embodiments, the reference current is used to characterize the static current of the detection resistor when all light-emitting units are in a de-energized state. Acquiring the reference current may include steps S210 to S230, as detailed below:

[0047] Step S210: Power off all interface branches.

[0048] Optionally, the controller has control pins for voltage control of the interface branches, thereby allowing the controller to power off all interface branches via the control pins.

[0049] Step S220: Obtain the first voltage of the detection resistor.

[0050] Step S230: Calculate the static current corresponding to the first voltage as the reference current based on the first voltage of the sensing resistor.

[0051] In one implementation, the controller can power off all interface branches. Furthermore, when all interface branches are in a power-off state, the controller can acquire the first voltage across the detection resistor and calculate the static current corresponding to the first voltage, thereby using the static current corresponding to the first voltage as the reference current.

[0052] Step S240: Determine the target interface branch among multiple interface branches. The target interface branch is any interface branch to be tested in the interface circuit.

[0053] In this embodiment, the specific implementation of step S240 can be referred to the description of step S130 provided in the above embodiment, and will not be repeated here.

[0054] Step S250: Power on the target interface branch and acquire the target detection current.

[0055] In some embodiments, when a target interface branch is identified, the target interface branch can be powered on, and further, the target detection current can be acquired. For details, please refer to [link to relevant documentation]. Figure 5 Step S250 may include steps S251 to S253.

[0056] Step S251: Power on the target interface branch and power off the other interface branches among the multiple interface branches.

[0057] Step S252: Obtain the second voltage of the detection resistor.

[0058] Step S253: Calculate the current corresponding to the second voltage of the detection resistor as the target detection current.

[0059] After powering off all interface branches and obtaining the reference current, in order to determine whether the target interface branch is connected to the light-emitting unit, only the target interface unit can be powered on to obtain the current of the detection resistor. Then, the current of the detection resistor is compared with the reference current to determine whether the target interface unit is connected to the light-emitting unit.

[0060] In one implementation, the controller can power on the target interface branch and de-power all other interface branches in the interface circuit except the target interface branch, thereby acquiring the voltage across the detection resistor, i.e., the second voltage. When the second voltage of the detection resistor is acquired, the current corresponding to the second voltage can be calculated as the target detection current.

[0061] In some embodiments, the target interface branch is accessed based on the reference current and the target detection current to obtain the detection result. Specifically, this may include steps S260 and S270.

[0062] Step S260: Obtain the current difference between the target detection current and the reference current.

[0063] In order to determine whether the target interface branch is connected to the light-emitting unit, after obtaining the reference current, when the control is only applied to the target interface branch, if the target interface branch is connected to the light-emitting unit, the current of the flow direction detection resistor in the light-emitting module will increase. Therefore, the increase in the current of the detection resistor can be used to determine whether the target interface branch is connected to the light-emitting unit.

[0064] As one implementation method, after obtaining the reference current and the target detection current, the difference between the reference current and the target detection current can be calculated to obtain the current difference value. For example, given the reference current... The difference between the current and the target detection current I is then calculated.

[0065] Step S270: Based on the relationship between the current difference and the preset difference, perform access detection on the target interface branch and obtain the detection result.

[0066] The preset difference refers to a difference predefined based on the configuration parameters of the light-emitting unit. Optionally, these configuration parameters may include at least the resistance value of the target light-emitting unit and the input / output current, which are not limited here. The corresponding preset difference can be determined based on these configuration parameters.

[0067] For example, based on the output current of the light-emitting unit, the current passing through the light-emitting module and the current passing through the detection resistor when the light-emitting module is connected to the light-emitting unit can be determined. Thus, a preset difference can be determined based on the current passing through the light-emitting module and the current passing through the detection resistor at this time. It is worth noting that the preset difference can be a numerical range.

[0068] In some embodiments, if the detection result shows that the current difference is greater than a preset difference, it can be determined that the light-emitting unit is connected to the light-emitting module. Optionally, when it is determined that the light-emitting unit is connected to the light-emitting module, that is, when the target interface branch is connected to the light-emitting unit, the number of light-emitting units can be incremented by 1. Further, other interface branches can be re-determined as new target interface branches, and the connection detection of the new target interface branches can be performed. Further, the determination of target interface branches and the connection detection of target interface branches can be repeated in sequence.

[0069] In other embodiments, if the detection result is that the current difference is not greater than a preset difference, it is determined that the light-emitting unit is connected to or not connected to the light-emitting module. Further, other interface branches can be re-determined as new target interface branches, and access detection is performed on the new target interface branches. Further, the determination of target interface branches and the access detection of target interface branches are repeated in sequence.

[0070] In this embodiment, by controlling the power off of all interface branches, a first voltage of the detection resistor is obtained. Based on the first voltage of the detection resistor, a reference current is obtained. Furthermore, the current difference between the target detection current and the reference current is obtained. Based on the magnitude of the current difference and a preset difference, the target interface branch is connected for detection to obtain the detection result. Thus, it is possible to determine the presence of a light-emitting unit based on the change in current in the light-emitting module circuit, which facilitates the determination of the number of light-emitting units in the light-emitting module.

[0071] During use, users may add or remove light-emitting units to create different splicing shapes depending on the usage scenario. Therefore, the number of light-emitting units in the light-emitting module will also change continuously. In order to facilitate users to design different lighting effects according to the number of light-emitting units, users need to know the number of light-emitting units in the light-emitting module in real time.

[0072] In some embodiments, the light-emitting module can repeatedly execute steps S110, S130, and S150 to sequentially perform access detection on multiple interface branches and obtain detection results. Further, based on the detection results, the number of accessed light-emitting units in the light-emitting module circuit is accumulated.

[0073] Specifically, after obtaining the reference current, the first interface branch in the interface circuit can be selected as the target interface branch, and the target interface branch can be powered on to obtain the target detection current. Based on the reference current and the target detection current, the target interface branch can be connected for detection. If it is determined that the target interface branch is connected to the light-emitting unit, that is, the first light-emitting unit is connected to the light source module, then the actual number of light-emitting units connected in the light source module is recorded as 1.

[0074] Furthermore, the first interface branch in the interface circuit is selected as the target interface branch, and the target interface branch is powered on to obtain the target detection current. Based on the reference current and the target detection current, the target interface branch is connected for detection. If it is determined that the target interface branch is connected to the light-emitting unit, that is, the first light-emitting unit is connected to the light source module, the actual number of light-emitting units connected in the light source module is recorded as 2. In this way, the interface branches in all interface circuits are connected for detection in sequence to obtain the detection results. Finally, the actual number of light-emitting units connected in the light source module is accumulated.

[0075] For example, there is a light-emitting module with three interface branches arranged sequentially in its interface circuit: a first interface branch, a second interface branch, and a third interface branch. The controller in the light-emitting module can de-energize these three interface branches to obtain a reference current. Further, the first interface branch is designated as the target interface branch. The controller only turns on the first interface branch and de-energizes the second and third interface branches. At this time, the target detection current is obtained, and the first interface branch is determined to be connected to the light-emitting unit based on the reference current and the target detection current. In this way, the second and third interface branches are designated as target interface branches in sequence, and the corresponding target detection currents are obtained to determine whether the second and third interface branches are connected to the light-emitting unit.

[0076] Furthermore, if it is determined that the first interface branch, the second interface branch, and the third interface branch are connected to the light-emitting unit in sequence, then it can be determined that the actual number of light-emitting units connected in the light-emitting module is 3.

[0077] Considering that there are many light-emitting units in splicable linear light-emitting modules in actual application scenarios, the scheme of determining the number of light-emitting units by sequentially detecting whether each interface branch is connected to a light-emitting unit has the problem of low execution efficiency. Therefore, a compromise detection scheme can be used to calculate the actual number of connected light-emitting units.

[0078] In other embodiments, the position numbers corresponding to multiple interface branches in the interface circuit can be obtained. Based on the position numbers, the interface branch with the last position number is identified as the target interface branch. Then, access detection is performed on the target interface branch. Optionally, the number of accessed light-emitting units in the light-emitting module circuit can be determined based on the detection results. The detection results may include: the target interface branch has access to light-emitting units, and the target interface branch has not had access to light-emitting units. It should be noted that the maximum value of the position number is the maximum number of accessed light-emitting units that the light-emitting module can support. Furthermore, access detection is performed on the last-ranked interface branch, thereby determining the number of accessed light-emitting units in the light source module based on the detection results.

[0079] Specifically, the interface circuit may include a first interface branch, a second interface branch, ..., an nth interface branch (n>1 and n∈N*). The nth interface branch is determined as the target interface branch. The last interface branch is checked for access. If the nth interface branch is connected to a light-emitting unit, the number of light-emitting units connected in the light source module is determined to be n. If the nth interface branch is not connected to a light-emitting unit, the process returns to steps S130, S150, and S170, and the number of light-emitting units connected in the light-emitting module circuit is determined according to the detection results, until the target interface branch to be detected is connected to a light-emitting unit. In this execution of step S130, the n / 2th interface branch can be determined as the target interface branch.

[0080] Furthermore, the n / 2nd interface branch is identified as the target interface branch. Access detection is performed on this last interface branch. If the n / 2nd interface branch is connected to a light-emitting unit, the number of connected light-emitting units in the light source module is determined to be n / 2. If the n / 2nd interface branch is not connected to a light-emitting unit, the n / 4th light-emitting unit is identified as the target interface branch.

[0081] ...

[0082] Furthermore, if the second interface branch is connected to a light-emitting unit, the number of light-emitting units connected in the light source module is determined to be 2; if the second interface branch is not connected to a light-emitting unit, the number of light-emitting units connected in the light source module is determined to be 1.

[0083] For example, there is a splicable light-emitting module that can support a maximum number of light-emitting units of 63. In order to speed up the detection of the number of light-emitting units, the interface branch with position number 64 can be used as the target interface branch, and it can be determined whether the target interface branch is connected to a light-emitting unit. If it is not connected, the interface branch with position number 32 can be used as the target interface branch, and it can be determined whether the interface branch is connected to a light-emitting unit. If it is connected, it can be determined that the actual number of light-emitting units connected in the light source module is 32.

[0084] Optionally, if not connected, the interface branch with position number 16 can be used as the target interface branch, and it can be determined whether the target interface branch is connected to the light-emitting unit. If not connected, the interface branch with position number 8 can be used as the target interface branch, and it can be determined whether the target interface branch is connected to the light-emitting unit. In this way, each time the target interface branch is detected not connected to the light-emitting unit, the method of selecting the target interface branch is used to determine whether the target interface branch is connected to the light-emitting unit. Finally, the light-emitting module with 64 light-emitting units can be detected in a maximum of 6 times.

[0085] After obtaining the number of light-emitting units in the light-emitting module, the number of light-emitting units can be monitored in real time. When some light-emitting units malfunction and cannot work, they can be repaired / replaced in a timely manner, preventing the overall lighting effect of the light-emitting module from being poor due to the absence of light-emitting units. In addition, users can adaptively design different lighting effects according to the actual number of light-emitting units.

[0086] In some embodiments, when the actual number of light-emitting units is obtained, a light-emitting instruction can be obtained. This light-emitting instruction is used to characterize the user's instruction to control the light-emitting module to emit light. For example, the light-emitting module can obtain the light-emitting instruction from the client. This light-emitting instruction can be generated by the client controlling the light-emitting module according to the user's needs for the light display effect of the light-emitting module.

[0087] Furthermore, after obtaining the light emission command, the light emission module can control the light emission based on the actual number of light emission units and the light emission command. For example, the light emission module can display a lighting effect, in which half of the light emission units in the light emission module display red light and the other half display green light. For instance, when the actual number of detected light emission units is 10, the first five light emission units can be displayed in red and the last five light emission units can be displayed in green; when the number of detected light emission units is 20, the first 10 light emission units can be displayed in red and the last 10 light emission units can be displayed in green.

[0088] In this embodiment, the actual number of light-emitting units in the light-emitting module is obtained by detecting whether the light-emitting unit is connected to the interface branch. This avoids the overall lighting display effect of the light-emitting module being affected by the absence of light-emitting units, allowing users to adaptively design the lighting display of the light-emitting module according to the actual number of light-emitting units and their needs, greatly improving the user experience.
