Technical Field

[0001] A multi-modulation light string, specifically referring to a multi-modulation light string component that arranges light-emitting diodes on two wires of the light string and controls the light-emitting diodes to flash and turn off, so as to achieve a variety of light-emitting effects. Background Technology

[0002] Currently, LED string lights are controlled by driving signals to activate LEDs. However, this method only allows for basic control of the LEDs and cannot meet users' visual requirements for varying LED patterns. Utility Model Content

[0003] In view of this, a multi-modulation light string is provided, comprising a first conductor, a second conductor, a control module, a first light-emitting diode (LED), and a light-emitting component. The control module is used to synthesize a communication command signal, a reset signal, and a drive signal to generate a synthesized signal and output it to the first conductor and the second conductor. The first LED is connected in parallel between the first conductor and the second conductor and is used to generate first light emission according to the synthesized signal. The light-emitting component is connected in parallel between the first conductor and the second conductor. The light-emitting component includes an LED group, a first control chip, and a second control chip. The LED group is used to generate modulated light emission when driven. The first control chip is used to drive the LED group to a light emission mode according to the communication command signal.

Wherein, the synthesized signal meets signal conditions in multiple low-level positions within each second, the signal conditions including: the total time length of these low-level positions does not exceed a first time threshold, and the number of these low-level positions is not less than 10; or the number of these low-level positions is less than 10, and the time length of each low-level position is not greater than a second time threshold; the first time threshold is greater than the second time threshold.

[0004] In some embodiments, the control module responds to multiple low levels of the synthesized signal within 1 second failing to meet the signal conditions by replacing the first control chip with a second control chip to execute the light emission mode.

[0005] In some embodiments, the LED group includes a second LED and a third LED. A first control chip drives the second LED, and a second control chip drives the third LED.

[0006] In some embodiments, the communication command signal further includes a constant-on command and a constant-off command. The control module selectively superimposes the constant-on command and the constant-off command onto the drive signal at the command frequency to generate a composite signal.

[0008] In some embodiments, the light-emitting component further includes a package, in which the second light-emitting diode, the first control chip, and the second control chip are packaged. The package has a first electrical connection terminal and a second electrical connection terminal. The first electrical connection terminal is coupled to a first wire and the first control chip, and the second electrical connection terminal is coupled to a second wire and the first control chip. The first control chip is electrically connected to the second light-emitting diode and communicatively connected to the second control chip.

[0009] In some embodiments, the light-emitting diode group includes a second light-emitting diode, and a second control chip and a third control chip drive the second light-emitting diode in turn; wherein, the control module is selectively configured to: generate the composite signal after generating the communication command signal with a master control command; wherein, the first control chip shuts down the second control chip according to the master control command; or generate the drive signal after generating the communication command signal with a switching command, wherein the first control chip drives the second light-emitting diode according to the communication of the second control chip.

[0010] In some embodiments, the light-emitting component further includes a package, in which the second light-emitting diode, the first control chip, and the second control chip are packaged. The package has a first electrical connection terminal and a second electrical connection terminal. The first electrical connection terminal is coupled to a first wire and the first control chip, and the second electrical connection terminal is coupled to a second wire and the first control chip. The first control chip is electrically connected to the second light-emitting diode and communicatively connected to the second control chip.

[0011] In some embodiments, the light-emitting component has a light-emitting address, and the communication command signal has a communication address. The light-emitting component generates modulated light emission when the light-emitting address matches the communication address.

[0012] In some embodiments, the light-emitting component further includes a package housing, in which a second light-emitting diode, a third light-emitting diode, a first control chip, and a second control chip are packaged. The package housing has a first electrical connection terminal and a second electrical connection terminal. The first electrical connection terminal is coupled to a first wire and the first control chip, and the second electrical connection terminal is coupled to a second wire and the first control chip. The first control chip is communicatively connected to the second control chip. The control module is selectively used to: generate a synthetic signal that intermittently emits a reset signal; or generate a communication command signal that has a constant-on command, and then generate a drive signal.

[0013] In some embodiments, when there are multiple first light-emitting diodes, one of the multiple first light-emitting diodes has a first conduction direction, and another of the multiple first light-emitting diodes has a second conduction direction, wherein the first conduction direction is opposite to the second conduction direction.

[0014] In some embodiments, there are multiple light-emitting components, one of which has a first conduction direction and another has a second conduction direction. The first conduction direction is opposite to the second conduction direction.

[0015] In some embodiments, the light-emitting component further includes a package, in which the light-emitting diode group, the first control chip, and the second control chip are packaged.

The first control chip is electrically connected to both the second control chip and the light-emitting diode group; in response to a switching command sent by the control module, the first control chip drives the second control chip to drive the light-emitting diode group according to a preset control timing sequence.

[0016] In summary, in some embodiments of the multi-modulation LED string, the control module can selectively carrier the communication command signal and reset signal onto the drive signal to generate a composite signal, which is then output to the first and second conductors. When the instructions of the communication command signal are too complex and do not meet the signal conditions (signal conditions include: the total duration of these low-level bits does not exceed a first time threshold, and the number of these low-level bits is not less than 10; or the number of these low-level bits is less than 10, and the duration of each low-level bit does not exceed a second time threshold), the control module can control the second control chip to replace the first control chip in performing the light emission mode. For example, the first control chip can be controlled to drive a portion of the LED groups to be constantly on or constantly off, and the second control chip can be controlled to drive another portion of the LED groups according to a preset control timing sequence corresponding to the specified light emission mode. Accordingly, the first LED will not be affected by the interference of the overly complex communication command signal, resulting in abnormal flickering (e.g., the first LED causing irregular flickering or unexpected brightness reduction).

[0070] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments to further understand the purpose, solution and effect of this utility model, but it is not intended to limit the scope of protection of the appended claims of this utility model.

[0071] like Figure 1 and Figure 2A As shown, the multi-modulation light string 100 includes a first conductor VIN1, a second conductor VIN2, a control module 102, a first light-emitting diode 104, and a light-emitting component 106. The control module 102 selectively combines a communication command signal S1, a drive signal S2, and a reset signal S4 to generate a combined signal S3, which is then output to the first conductor VIN1 and the second conductor VIN2. The first light-emitting diode 104 is connected in parallel between the first conductor VIN1 and the second conductor VIN2 and is used to generate first light emission according to the combined signal S3. The light-emitting component 106 is connected in parallel between the first conductor VIN1 and the second conductor VIN2. The light-emitting component 106 includes a light-emitting diode group 108, a first control chip 112, and a second control chip 114. The light-emitting diode group 108 generates modulated light emission when driven. The first control chip 112 drives the light-emitting diode group 108 to a light emission mode according to the communication command signal S1. The second control chip 114 controls the light emission according to the drive signal S2 and a preset control timing CT corresponding to the light emission mode (see [reference needed]). Figure 5AThe system drives the LED group 108 and resets the preset control timing CT in response to the low level of the communication command signal S1 or the reset signal S4. The synthesized signal S3 meets signal conditions for multiple low levels within each second. These conditions include: the total duration of these low levels does not exceed a first time threshold, and the number of these low levels is not less than 10; or the number of these low levels is less than 10, and the duration of each low level does not exceed a second time threshold. The first time threshold is greater than the second time threshold.

[0072] The control module 102 can be connected to a power supply to obtain an input voltage from the power supply. For example... Figure 1 The control module 102 has a first input terminal VDD and a second input terminal GND. There is a potential difference between the first input terminal VDD and the second input terminal GND, which enables the operation of the control module 102, the first light-emitting diode 104 and the light-emitting diode group 108.

[0073] In some embodiments, after the first wire VIN1 and the second wire VIN2 are connected to the control module 102, the first input terminal VDD and the second input terminal GND generate high and low potentials, respectively. This can mean that the first input terminal VDD receives a high potential (operating voltage) and the second input terminal GND receives a low potential (ground voltage). Alternatively, it can mean that the first input terminal VDD receives a low potential and the second input terminal GND receives a high potential.

[0074] In some embodiments, the first conductor VIN1 is parallel to the second conductor VIN2, and the first light-emitting diode 104 and the light-emitting component 106 are respectively coupled between the first conductor VIN1 and the second conductor VIN2 to form a long strip-shaped light string structure. Furthermore, the control module 102 sends a combined signal S3 through the first conductor VIN1 and the second conductor VIN2 to control the first light-emitting diode 104 and the light-emitting diode group 108 to light up or turn off.

[0075] The control module 102 may be, for example, a central processing unit (CPU), microcontroller unit (MCU), digital signal processor (DSP), application specific integrated circuit (ASIC), or other circuit combination capable of outputting the aforementioned synthesized signal S3. The control module 102 may trigger the first light-emitting diode 104 and the light-emitting component 106 to emit light or modulate light based on the high and low levels of the synthesized signal S3. For example, when the synthesized signal S3 is at a high level, the first light-emitting diode 104 and the light-emitting diode group 108 are connected to the two wires (VIN1, VIN2) and emit light. Or, for example, when the synthesized signal S3 is at a low level, the first light-emitting diode 104 and the light-emitting diode group 108 are not connected to the two wires (VIN1, VIN2) and do not emit light.

[0076] In some embodiments, the aforementioned "multiple low-level positions of the synthesized signal S3 within each second meet the signal conditions, the signal conditions including: the total duration of these low-level positions does not exceed a first time threshold, and the number of these low-level positions is not less than 10; or the number of these low-level positions is less than 10, and the duration of each low-level position does not exceed a second time threshold" can refer to the control module 102 determining whether the synthesized signal S3 meets the signal conditions every second. The first time threshold can be from 0.2 seconds to 0.4 seconds. The second time threshold can be from 20 milliseconds to 30 milliseconds. It should be noted that the range of the first and second time thresholds can be determined based on the different perceptions of brightness changes in each individual's eye. The following example uses a first time threshold of 0.3 seconds and a second time threshold of 30 milliseconds to illustrate this. This threshold range is suitable for the perception of most human eyes, but it can also be adjusted according to product requirements and is not limited to the values ​​in this example. For example... Figure 2A As shown, 1 second can be used to instantly examine a continuous segment of the synthesized signal S3 within a predetermined continuous time window TW. For example... Figure 2A As shown, the number of low-level points within the predetermined continuous time window TW is not less than 10. Figure 2A (The middle one is 11), and the total time of these low-level signals is less than 0.3 seconds, indicating that the synthesized signal S3 captured within the predetermined continuous time window TW meets the signal conditions. For example... Figure 2B As shown, the number of low-level points within the predetermined continuous time window TW is less than 10. Figure 2B (There are 4 in total), but the duration of each low level (t1, t2, t3, t4) is no greater than 30 milliseconds. Figure 2BThe synthesized signal S3 captured within the predetermined continuous time window TW still meets the signal conditions. According to the aforementioned example, if the synthesized signal S3 captured within the predetermined continuous time window TW meets the signal conditions, it means that the distribution of multiple low-level positions in this segment of the synthesized signal S3 is unlikely to cause irregular flickering or unexpected brightness reduction in the first emission. Conversely, if the synthesized signal S3 does not meet the signal conditions, it means that the distribution of multiple low-level positions in this segment of the synthesized signal S3 may cause visually irregular flickering or unexpected brightness reduction in the first emission.

[0077] Accordingly, the control module 102 can use the second control chip 114 instead of the first control chip 112 to perform the expected light emission mode. Since the second control chip 114 drives a portion of the light-emitting diode group 108 (such as the third light-emitting diode 110 described later) with the stored expected light emission mode, the control module 102 can simplify the communication command signal S1 (described later) to avoid low-level interference with the light emission of the first light-emitting diode 104 in the composite signal S3 of some light emission modes.

[0078] In some embodiments, the control module 102 can receive control commands and generate a composite signal S3 based on the control commands. The control commands may be pre-stored in the control module 102, and when driven, the control module 102 can access the control commands to generate and send the composite signal S3. Alternatively, the control commands may be sent to the control module 102 by an electronic device (e.g., a mobile phone, computer, or tablet computer with wireless transmission capabilities) located outside the multi-modal light string 100, allowing the control module 102 to receive the control commands via a wireless transmission channel and generate and send the composite signal S3 accordingly. Thus, the user can input the corresponding control command into the electronic device according to the desired light emission mode to remotely adjust the change in the first or second light emission.

[0079] The first light-emitting diode 104 and the light-emitting diode group 108 can be micro light-emitting diodes (LEDs), organic light-emitting diodes (OLEDs), quantum dot LEDs (QLEDs), mini LEDs, and polymer light-emitting diodes (PLEDs). "First light emission" or "modulated light emission" refers to the light-emitting action (presenting a light-emitting state) produced when the corresponding first light-emitting diode 104 or light-emitting diode group 108 is driven. In some embodiments, the first light-emitting diode 104 can be a single-color LED arranged between the first conductor VIN1 and the second conductor VIN2. Alternatively, it can be composed of multiple colors arranged sequentially between the first conductor VIN1 and the second conductor VIN2, allowing the multi-modulation light string 100 to produce different visual effects. In some embodiments, the number of light-emitting diode groups 108 can be single or multiple. The light-emitting diode group 108 can also be a single-color LED arranged between the first conductor VIN1 and the second conductor VIN2, or multiple colors arranged sequentially between the first conductor VIN1 and the second conductor VIN2. In some embodiments, the LED group 108 includes a second LED 109 and a third LED 110. A first control chip 112 is coupled to the second LED 109 to control the second LED 109 to modulate its light emission. A second control chip 114 is coupled to the third LED 110 to control the third LED 110 to modulate its light emission. The control actions of the first control chip 112 and the second control chip 114 will be distinguished below by the light emission actions of the second LED 109 and the third LED 110.

[0080] In some embodiments, such as Figure 2A As shown, the driving signal S2 can refer to a combination of high or low levels generated by the first wire VIN1 and the second wire VIN2. For example, when the driving signal S2 is at a high level, the first LED 104, the second LED 109, and the third LED 110 can respectively generate first light emission and modulated light emission. When the driving signal S2 is at a low level (input voltage is 0V), the first LED 104, the second LED 109, and the third LED 110 will not generate first light emission and modulated light emission (they will be in an off state). In some embodiments, such as Figure 2BAs shown, the control module 102 can also set the low level of the synthesized signal to half the high level. It should be noted that if the communication command signal S1 and the drive signal S2 do not reach the low level, the second control chip 114 will not be triggered by the level (half the high level) of the communication command signal S1 and the drive signal S2. Conversely, the reset signal S4 remains at the low level, allowing the second control chip 114 to successfully reset the preset control timing CT when it receives the reset signal S4.

[0081] The first control chip 112 is coupled to the second light-emitting diode 109 and is used to drive the second light-emitting diode 109 according to the communication command signal S1. For example, when the first control chip 112 maintains a low level according to the communication command signal S1, the first control chip 112 can control the second light-emitting diode 109 not to produce modulated light (remain off). When the first control chip 112 maintains a high level according to the communication command signal S1, the first control chip 112 can control the second light-emitting diode 109 to maintain light (maintain light). It should be noted that since the communication command signal S1 is carrier-to-carry signal S2, if the first control chip 112 controls the second light-emitting diode 109 to emit light according to the communication command signal S1, and the driving signal S2 is also at a low level at this time, the second light-emitting diode 109 will not emit light. Conversely, if the driving signal S2 is at a high level, the second light-emitting diode 109 will emit light. In some embodiments, the first control chip 112 and the second light-emitting diode 109 can be packaged into a separate light-emitting element.

[0082] After receiving the drive signal S2, the second control chip 114 can select a preset control timing CT with a specified preset light emission mode to control the third light-emitting diode 110 to modulate light emission. In some embodiments, the preset light emission mode can be a control program stored in the second control chip 114 to execute the corresponding light emission mode. For example, a star flashing mode or a breathing mode (described later). For instance, in the preset light emission mode, the third light-emitting diode 110 can modulate light emission according to the changes in the low and high levels of the preset control timing CT. In some embodiments, the second control chip 114 and the third light-emitting diode 110 can be packaged into a separate light-emitting element.

[0083] In some embodiments, different preset emission modes each have a corresponding preset control timing sequence (CT). The control module 102 can drive the second control chip 114 to execute the specified preset control timing sequence CT. For example, the control command can set one of the preset control modes, and the control module 102 can send a corresponding switching command according to the specified preset control mode (the switching command can be a segment of code for the high and low levels). Upon receiving this switching command, the second control chip 114 can execute the preset control timing sequence CT of the specified preset control mode. The second control chip 114 can reset the preset control timing sequence CT according to the reset signal S4 (described later).

[0084] In some embodiments, the first control chip 112 can identify the communication command signal S1 and the reset signal S4, preventing the first control chip 112 from driving the second light-emitting diode 109 with the reset signal S4. Alternatively, even if the first control chip 112 cannot identify the reset signal S4, since the reset signal S4 is shorter than the duration of the communication command signal S1, the change in the light emission effect of the second light-emitting diode 109 due to the reset signal S4 is imperceptible to the naked eye. Therefore, the reset signal S4 does not affect the communication command signal S1. The reset signal S4 can also be a control action by the control module 102 to adjust the voltage drop between the first wire VIN1 and the second wire VIN2 to 0V. Here, by briefly de-energizing the second control chip 114, the second control chip 114 can reset the preset control timing CT. It should be noted that the second control chip 114 has internal memory, and since the power-off time of the reset signal S4 on the second control chip 114 is shorter than the time during which the memory clears the preset control timing CT of the specified light emission mode. Therefore, even if the preset control timing sequence (CT) being executed is reset, the second control chip 114 can still re-execute the preset control timing sequence (CT) for the specified light emission mode, and the control module 102 does not need to resend control commands to drive the second control chip 114 to perform the specified light emission mode.

[0085] In some embodiments, when the first control chip 112 controls the second light-emitting diode 109 to modulate light emission in a specified light emission mode according to the synthesized signal S3, the second control chip 114 can control the third light-emitting diode 110 to remain constantly lit or constantly off. Conversely, when the second control chip 114 controls the third light-emitting diode 110 to modulate light emission in a specified light emission mode according to the reset signal S4 and the drive signal S2, the first control chip 112 can control the second light-emitting diode 109 to remain constantly lit or constantly off (details to follow).

[0086] For example Figure 1As shown, in some embodiments, the light-emitting component 106 has a light-emitting address, and the communication command signal S1 has a communication address. The light-emitting component 106 generates modulated light emission when the light-emitting address matches the communication address. For example, the multimodal LED string 100 can connect one or more light-emitting components 106 in parallel, each light-emitting component 106 having a different light-emitting address, such as... Figure 2A or Figure 2B As shown, the light-emitting address of the first light-emitting component 106 can be, for example, a first light-emitting address, and the light-emitting address of the second light-emitting component 106 can be, for example, a modulation light-emitting address. When the communication address in the communication command signal S1 sent by the control module 102 is the first light-emitting address, the second light-emitting diode 109 of the first light-emitting component 106 generates modulated light emission when the first light-emitting address matches the communication address. Conversely, when the modulation light-emitting address of the second light-emitting component 106 does not match the communication address, the second light-emitting diode 109 of the second light-emitting component 106 will not generate modulated light emission. In this way, the user can control the second light-emitting diode 109 of the light-emitting component 106 at the specified address to generate modulated light emission by generating a communication command signal S1 corresponding to the specified light-emitting address through the control module 102. In some embodiments, the reset signal S4 does not have an address. The control module 102 can connect the second control chip 114 between the first wire VIN1 and the second wire VIN2. The second control chip 114 can synchronously receive the reset signal S4 to control all the third light-emitting diodes 110 on the multi-modulation light string 100 to modulate the light emission effect.

[0087] like Figure 3 As shown, in some embodiments, the communication command signal S1 may include a constant-on command C1. The composite signal S3 is the superposition of the constant-on command C1 and the driving signal S2. It should be noted that when the communication command signal S1 is the constant-on command C1, the first control chip 112 can maintain the output at a high level for a preset light-emitting time, so that the second light-emitting diode 109 continuously emits light for the preset light-emitting time. Then, after the preset time ends, the first control chip 112 outputs a low level, so that the second light-emitting diode 109 turns off. In some embodiments, the control module 102 can superimpose the constant-on command C1 on the driving signal S2 at the corresponding command frequency according to the specified light-emitting mode to generate the composite signal S3. Accordingly, the second light-emitting diode 109 can modulate the light emission according to the command frequency. In this embodiment, the period of the low level between the two high levels can be the later constant-off command C2 (described later). Figure 4 The command frequency can refer to a time interval below the time during which the light emission change is perceptible to the human eye (it can refer to less than 1 / 30 of a second). This allows the constant-on command C1 to be superimposed on the drive signal S2, so that the second light-emitting diode 109 of the light-emitting component 106 can be constantly lit visually, and each of the first light-emitting diodes 104 will also remain constantly lit without being interfered with by the constant-on command C1.

[0088] like Figure 4 As shown, in some embodiments, the communication command signal S1 includes a constant-on command C1 and a constant-off command C2. The first control chip 112 controls the second light-emitting diode 109 to generate modulated light emission according to the constant-on command C1, and does not generate modulated light emission according to the constant-off command C2. Figure 4 As shown, the control module 102 selectively superimposes the constant-on command C1 and the constant-off command C2 onto the drive signal S2 at a command frequency to generate a composite signal S3. For example, when the control module 102 superimposes the constant-on command C1 onto the composite signal S3, the first control chip 112 can output a high level according to the constant-on command C1 to control the second light-emitting diode 109 to generate modulated light. The first control chip 112 can control the second light-emitting diode 109 not to generate modulated light according to the constant-off command C2. In some embodiments, when the first control chip 112 executes the star-like flashing mode, it can shorten the time from the constant-on command C1 to the constant-off command C2 (this is the time for modulated light emission) and increase the time from the constant-off command C2 to the constant-on command C1 (this is the time for the off duration). Here, the duration of modulated light emission is less than the off time to produce a star-like flashing light effect. The first light-emitting diode 104 and the third light-emitting diode 110 can maintain light emission. In some embodiments, the control module 102 can also set the low level of the constant-on command C1 and the constant-off command C2 to 1 / 2 of the high level while keeping the high level unchanged, thereby triggering the first control chip 112 to output a high level or a low level to control the second light-emitting diode 109.

[0089] For example Figure 1 and Figure 5A and Figure 5B As shown. In some embodiments, as Figure 5A As shown, after receiving the drive signal S2, the second control chip 114 will drive the third light-emitting diode 110 to modulate light emission according to a preset control timing CT based on a specific light emission mode. Figure 5B As shown, according to the selected light emission mode, the control module 102 intermittently sends a reset signal S4 within a preset control timing CT (which can be between the preset control timing CT changing from a high level to a low level). The preset control timing CT is continuously reset and maintained at a high level, causing the third light-emitting diode 110 to continue generating modulated light emission (i.e., as shown in the image). Figure 5B The preset control timing CT maintains a high level. Accordingly, drive signal S2 at timing M1 (see...) Figure 6When the timing M1 is shown, the first LED 104 and the third LED 110 can generate first light emission and modulated light emission, while the second LED 109 can light up and turn off according to the configuration time of the constant-on command C1 and constant-off command C2 in the communication command signal S1 to perform visual effects of different light emission modes. In some embodiments, the reset signal S4 is a low-level signal. When the second control chip 114 receives the low-level signal, it can reset the preset control timing CT. In other words, the second control chip 114 can use the low level in the synthesized signal S3 as the reset signal S4.

[0090] In some embodiments, according to the aforementioned control instructions for the first light-emitting diode 104, the second light-emitting diode 109, and the third light-emitting diode 110, the control module 102 can carrier the communication command signal S1 and the reset signal S4 onto the drive signal S2 according to different light-emitting modes to generate a composite signal S3 corresponding to the light-emitting mode. In some embodiments, the control module 102 can also carrier the communication command signal S1 and the reset signal S4 onto the drive signal S2 according to the control command to control the second light-emitting diode 109 and the third light-emitting diode 110 to simultaneously perform modulated light emission.

[0091] In some embodiments, a breathing mode is exemplified by using a first light-emitting diode 104, a second light-emitting diode 109, and a third light-emitting diode 110. The control module 102 can continuously adjust the duty cycle of the communication command signal S1 (e.g., ...). Figures 6 to 8 The first light-emitting diode (LED) and the modulated light-emitting diode (EMD) continuously cycle through a process of gradually brightening and dimming. In this way, each LED (104, 108, 110) can achieve the visual effect of a breathing light. In some embodiments, the control module 102 can also intermittently send a reset signal S4 to drive the third LED 110 to maintain its illumination. In some embodiments, the control module 102 can send a communication command signal S1 before adjusting the duty cycle, allowing the first control chip 112 to first perform the specified illumination effect before adjusting the brightness.

[0092] In some embodiments, the communication command signal S1 and the reset signal S4 are transmitted to the first wire VIN1 and the second wire VIN2 at a frequency of more than 10 ms per second, carried by the drive signal S2. The pulse width of the reset signal S4 is set to be greater than 1 microsecond and between several milliseconds. Therefore, the impact of the communication command signal S1 and the reset signal S4 on the first light-emitting diode 104 is less than the time it takes for the human eye to perceive a change in light emission, and it does not affect the visual effect of the first light emission. Furthermore, the control module 102 can adjust the timing of the communication command signal S1, the drive signal S2, and the reset signal S4 to achieve different light emission modes. For example, the timing of the constantly lit command C1 and / or the constantly dark command C2 in the communication command signal S1, the timing of the high and low potentials in the drive signal S2, or the transmission timing of the reset signal S4.

[0093] like Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the driving signal S2 is a pulse width modulation (PWM) signal, and multiple first light-emitting diodes 104 selectively generate first light emission according to the PWM signal. This can refer to the situation where the PWM signal is at a high level (e.g., when the PWM signal is at a high level). Figure 6 In the middle timing (M1), the first light-emitting diode 104 emits light. When the pulse width modulation signal is at a low level (e.g., ...), the first light-emitting diode 104 emits light. Figure 6 In the middle timing (M2), the first light-emitting diode 104 does not emit light. Thus, the control module 102 can adjust the pulse width modulation signal to change the brightness or emission timing of the first light-emitting diode 104. In some embodiments, when the first light-emitting diode 104 is set to always-on, the control module 102 can continuously update the duty cycle of the pulse width modulation signal, so that the first light-emitting diode 104 can visually appear to be in a continuously lit state. For example... Figure 6 For example, the ratio of timing M1 to timing M2 is 1 / 10, and the initial brightness can be visually presented as 10% brightness. (For example...) Figure 7 For example, when the ratio of timing M1 to timing M2 is 1 / 2, the second brightness can be visually presented as 50% brightness. For example... Figure 8 For example, timing M1 is much larger than timing M2, and the second brightness can visually appear to be close to 100% brightness. In some embodiments, the brightness of the second LED 109 and the third LED 110 can also be changed by adjusting the duty cycle of the pulse width modulation signal (the ratio of timing M1 to timing M2). The brightness of the second LED 109 and the third LED 110 also varies with the change in the duty cycle of the pulse width modulation signal. Accordingly, the control module 102 can adjust the duty cycle of the pulse width modulation signal to simultaneously change the brightness of the first LED 104, the second LED 109, and the third LED 110, achieving the visual effect of each LED (104, 108, 110) simultaneously performing a breathing light effect. In addition, the light emission mode also includes candle flickering, which can be achieved by adjusting the brightness of the modulated light emission to rapidly change, forming an effect similar to flickering candlelight. The aforementioned unexpected decrease in brightness of the first light-emitting diode 104 may refer to an abnormal light-emitting situation (abnormal flickering or decreased brightness) caused by multiple low-level positions in the complex synthetic signal S3 within 1 second failing to meet the signal conditions, rather than by adjusting the duty cycle of the pulse width modulation signal.

[0094] In some embodiments, the aforementioned "control module 102 responds to multiple low-level failures of the synthetic signal S3 within 1 second to replace the first control chip 112 in executing the light emission mode" can mean that when the synthetic signal S3 fails to meet the signal conditions, the control module 102 only transmits a single constant-on command C1 or a single constant-off command C2 to the drive signal S2, so that the generated synthetic signal S3 has only a single constant-on command C1 or a single constant-off command C2. Here, the first control chip 112 can control the second light-emitting diode 109 to remain constantly on or off during this light emission mode based on the single constant-on command C1 or the single constant-off command C2. Then, the control module 102 does not output a reset signal S4, and the second control chip 114 does not reset the preset control timing CT without receiving the reset signal S4, causing the third light-emitting diode 110 to perform the specified light emission mode according to the preset control timing CT. The first light-emitting diode 104 and the second light-emitting diode 109 can remain constantly on to enhance the overall visual effect of the multi-modulation light string 100. Alternatively, the first control chip 112 may execute a specified light-emitting mode. However, because the visual effect that the light-emitting mode is intended to present is complex, it may be difficult to transmit the complex communication command signal S1 to the drive signal S2. The control module 102 can control the sending of a switching command to drive the second control chip 114 to execute the specified light-emitting mode (such as blinking, breathing, candle flashing, or star flashing functions) instead of the first control chip 112.

[0095] like Figure 9 As shown, in some embodiments, there may be multiple first light-emitting diodes 104. One of these first light-emitting diodes 104 has a first conduction direction P1, and another of these first light-emitting diodes 104 has a second conduction direction P2, wherein the first conduction direction P1 and the second conduction direction P2 are opposite. For example, Figure 9 The plurality of first light-emitting diodes 104 are distinguished into first light-emitting diodes 104a and first light-emitting diodes 104b according to their conduction directions. When the conduction direction of the first light-emitting diode 104a is the first conduction direction P1, the first light-emitting diode 104a can generate first light emission according to the driving signal S2, while the first light-emitting diode 104b does not generate first light emission. Conversely, when the conduction direction of the driving signal S2 is the second conduction direction P2, the first light-emitting diode 104b can generate first light emission according to the driving signal S2, while the first light-emitting diode 104a does not generate first light emission. In some embodiments, the first light-emitting diodes (104a, 104b) can be adapted to driving signals S2 with different conduction directions. Thus, the first light-emitting diodes 104a and 104b can be light-emitting diodes of the same or different colors, producing a visual effect of different colors of light emitting in turn.

[0096] like Figure 10As shown, there are multiple light-emitting components 106. One of these light-emitting components 106 has a first conduction direction P1, and another of these light-emitting components 106 has a second conduction direction P2. The first conduction direction P1 and the second conduction direction P2 are opposite. For example, Figure 10 The light-emitting component 106 is divided into a first light-emitting component 116 and a second light-emitting component 118 according to the conduction direction. When the conduction direction of the first light-emitting component 116 is a first conduction direction P1, the first light-emitting component 116 can generate modulated light emission according to the communication command signal S1, while the second light-emitting component 118 does not generate modulated light emission. Conversely, when the conduction direction of the communication command signal S1 is a second conduction direction P2, the second light-emitting component 118 can generate modulated light emission according to the communication command signal S1, while the first light-emitting component 116 does not generate modulated light emission. Therefore, the first light-emitting component 116 and the second light-emitting component 118 can be adapted to communication command signals S1 with different conduction directions. For example, the first light-emitting component 116 and the second light-emitting component 118 (e.g., referring to...) Figure 10 The light-emitting component 106 can be light-emitting diodes of the same or different colors, producing a visual effect of different colors of light emitting light in turn.

[0097] In some embodiments, the multimodal light string 100 further includes multiple resistors R (such as...). Figure 10(As shown). One end of resistor R is coupled to the first LED 104, and the other end is coupled to one of the first wire VIN1 and the second wire VIN2. For example, in some cases, the voltage at the first input terminal VDD is 3V, and the voltage drop of the first LED 104 may be reduced by the line resistance of the first wire VIN1 and the second wire VIN2 (e.g., down to 2.8V). The voltage drop input to the second LED 109 and the third LED 110 may be reduced to 2.3V by the electronic components of the first control chip 112 or the second control chip 114 (e.g., the electronic switching element has a voltage drop of 0.7V). Therefore, the voltage drops of the first LED 104 and the second LED 109 (or the third LED 110) are not consistent, resulting in a visual difference in brightness between the first LED 104 and the second LED 109. In some embodiments, resistors R can be provided on the first light-emitting diode 104 to adjust the voltage drop of the first light-emitting diode 104, so that the brightness of the first light-emitting diode 104, the second light-emitting diode 109, and the third light-emitting diode 110 is close to or consistent. In some embodiments, resistor R includes a first resistor R1 and a second resistor R2. One end of the first resistor R1 is coupled to the N terminal of the first light-emitting diode 104a, and the other end is coupled to the second wire VIN2. One end of the second resistor R2 is coupled to the N terminal of the first light-emitting diode 104b, and the other end is coupled to the first wire VIN1. The multi-modal light string 100 can adjust the voltage of the first light-emitting diode 104a and the first light-emitting diode 104b through the first resistor R1 and the second resistor R2, so that the brightness of the first light-emitting diode 104a, the first light-emitting diode 104b, the first light-emitting component 116, and the second light-emitting component 118 is visually consistent. In some embodiments, resistor R can be encapsulated within the first light-emitting diode 104 so as not to affect the visual effect of the first light-emitting diode 104 on the multi-modal light string 100.

[0098] like Figure 11 As shown, the multi-modulation lamp string 200 includes a first conductor VIN1, a second conductor VIN2, a control module 202, and multiple light-emitting groups 203. The control module 202 combines the communication command signal S1 and the drive signal S2 to generate a combined signal S3, which is then output to the first conductor VIN1 and the second conductor VIN2. Multiple light-emitting groups 203 are connected in series with the control module 202. Each light-emitting group 203 includes multiple first light-emitting diodes 204 and light-emitting components 206. The control module 202 can be referenced... Figure 1 The description of the control module 102 shown is provided below. The first light-emitting diode 204 can be found in the following reference. Figure 1 The description of the first light-emitting diode 104 is shown. The light-emitting component 206 can be found in the following reference. Figure 1The description of the light-emitting component 106 is as follows. The light-emitting component 206 further includes a light-emitting diode group 208, a first control chip 212, and a second control chip 214. The light-emitting diode group 208 includes a second light-emitting diode 209 and a third light-emitting diode 210. (See reference...) Figure 1 Description of the first light-emitting diode 104, the light-emitting diode group 108, the second light-emitting diode 109, the third light-emitting diode 110, the first control chip 112, and the second control chip 114 shown.

[0099] In some embodiments, Figure 11 The first light-emitting diode 204 is divided into a first light-emitting diode 204a and a first light-emitting diode 204b according to its conduction direction. When the conduction direction of the first light-emitting diode 204a is a first conduction direction P1, the first light-emitting diode 204a can emit light according to the driving signal S2, while the first light-emitting diode 204b does not emit light. Conversely, when the conduction direction of the driving signal S2 is a second conduction direction P2, the first light-emitting diode 204b can emit light according to the driving signal S2, while the first light-emitting diode 204a does not emit light. In some embodiments, the polarity of the first light-emitting diodes 204a and 204b can be adapted to driving signals S2 with different conduction directions.

[0100] The aforementioned "light-emitting group 203 connected in series with control module 202" may refer to Figure 11 The first light-emitting group 2031 and the second light-emitting group 2032 are connected in series, with the first light-emitting group 2031 coupled to one end of the control module 202 and the second light-emitting group 2032 coupled to the other end of the control module 202 to form a loop. It should be noted that the input voltage of a single light-emitting group 203 is 3V. Figure 11 The multi-modulation light string 200 has two groups of light-emitting groups (2031, 2032), and its input voltage is approximately 9V. Taking a multi-modulation light string 200 connected in series with nine light-emitting groups 203 as another example, the nine light-emitting groups 203 operate at 27V. Considering the resistance of the first wire VIN1 and the second wire VIN2, the input voltage can be set to 31V, and so on. In some embodiments, the multi-modulation light string 200 can also be connected in series with more than three light-emitting groups 203.

[0101] like Figure 12As shown, there can be multiple light-emitting components 206. The light-emitting components 206 are divided into a first light-emitting component 216 and a second light-emitting component 218 according to their conduction direction. When the conduction direction of the first light-emitting component 216 is the first conduction direction P1, the first light-emitting component 216 can generate first light emission according to the communication command signal S1, while the second light-emitting component 218 does not generate first light emission. Conversely, when the conduction direction of the communication command signal S1 is the second conduction direction P2, the second light-emitting component 218 can generate first light emission according to the communication command signal S1, while the first light-emitting component 216 does not generate first light emission. Thus, the multiple light-emitting groups (2031, 2032) connected in series in the multi-modulation lamp string 200 can be adapted to the polarity of the communication command signal S1 to control the first light-emitting component 216 or the second light-emitting component 218 of each light-emitting group (2031, 2032) to generate second light emission. Figure 12 In the illustrated embodiment, any light-emitting group (2031, 2032) comprises first light-emitting diodes (204a, 204b) with different conduction directions and light-emitting components 206 (first light-emitting component 216 and second light-emitting component 218) with different conduction directions. Therefore, the communication address of any light-emitting group (2031, 2032) can be set according to the different light-emitting groups (2031, 2032), so that the first light-emitting component 216 and the second light-emitting component 218 in the group can be controlled by a single communication address.

[0102] exist Figure 11 or Figure 12 In this embodiment, the control module 202 outputs a synthesized signal S3 to the first wire VIN1 and the second wire VIN2, which can simultaneously control the first light-emitting group 2031 and the second light-emitting group 2032. For example, when the driving signal S2 is at a high potential, the first light-emitting diode 204 of each light-emitting group (2031, 2032) can generate first light emission. When the driving signal S2 is at a low potential, the first light-emitting diode 204 of each light-emitting group (2031, 2032) will not generate first light emission (it is in an off state). As another example, when the communication command signal S1 is a light emission signal, the first control chip 212 can drive the second light-emitting diode 209 to generate modulated light emission. In this way, the control module 202 can output a single communication command signal S1 to simultaneously control multiple light-emitting groups (2031, 2032), thereby improving the control performance of the multi-modulation light string 200. Furthermore, in response to the communication command signal S1 exceeding half the duty cycle of the synthesized signal S3, the control module 202 can load a reset signal S4 onto the communication command signal S1, and will not load either the constant-on command C1 or the constant-off command C2 onto the communication command signal S1. Consequently, the first control chip 212 will not drive the second light-emitting diode 209 to generate modulated light, while the second control chip 214 will drive the third light-emitting diode 210 to generate modulated light.

[0103] like Figure 13As shown, in some embodiments, the light-emitting component further includes a package 120. The light-emitting diode group 208 includes a second light-emitting diode 209. The second light-emitting diode 109, the first control chip 112, and the second control chip 114 are packaged within the package 120. The package 120 has a first electrical connection terminal 122 and a second electrical connection terminal 124. The first electrical connection terminal 122 is coupled to a first wire VIN1 and the first control chip 112. The second electrical connection terminal 124 is coupled to a second wire VIN2 and the first control chip 112. The second control chip 114 is communicatively connected to the first control chip 112. The control module 102 is selectively configured to: generate a communication command signal S1 with a master control command and then continuously generate a synthesized signal S3, wherein the first control chip 112 shuts down the second control chip 114 according to the master control command; or generate a drive signal after generating a communication command signal S1 with a switching command, wherein the first control chip 112 drives the second light-emitting diode 109 according to the communication of the second control chip 114. Specifically, in response to the synthesized signal S3 meeting the signal condition (indicating that the synthesized signal S3 does not affect the visual effect of the first light emission), the control module 102 generates a communication command signal S1 with a master control command and then continuously generates the synthesized signal S3. Next, the first control chip 112 shuts down the second control chip 114 (the first control chip 112 can communicate) with a master control command and drives the second light-emitting diode 109 according to the communication command signal S1. Here, the second light-emitting diode 109 is driven by the first control chip 112. Furthermore, in response to the synthesized signal S3 not meeting the signal condition (indicating that the synthesized signal S3 may affect the visual effect of the first light emission), the control module 102 generates a communication command signal S1 with a switching command and then generates a drive signal S2. The aforementioned "the first control chip 112 drives the second light-emitting diode 109 according to the communication of the second control chip 114" can mean that the first control chip 112 transmits the switching command to the second control chip 114, causing the second control chip 114 to send back the preset control timing CT to the first control chip 112. Next, in response to the first control chip 112 receiving the preset control timing sequence CT, the first control chip 112 can drive the second light-emitting diode 109 according to the timing change of the high level to the low level of the preset control timing sequence CT. In other words, in this case, the control module 102 does not add the constant-on command C1 and the constant-off command C2 to the communication command signal S1, but instead adds a switching command to the communication command signal S1. The switching command can be a series of signals encoded with high level and low level. Accordingly, the first control chip 112 and the second control chip 114, which are packaged together, can individually drive the second light-emitting diode 109 according to conditions, so as to avoid the first control chip 112 and the second control chip 114 driving the second light-emitting diode 109 at the same time, which would cause the second light-emitting diode 109 to emit light abnormally. In some embodiments, the first control chip 112 and the second control chip 114 can also be replaced by a single chip.

[0104] like Figure 14 As shown, in some embodiments, the second light-emitting diode 109, the third light-emitting diode 110, the first control chip 112, and the second control chip 114 are packaged within a package 120. The package 120 has a first electrical connection terminal 122 and a second electrical connection terminal 124. The first electrical connection terminal 122 is coupled to the first wire VIN1 and the first control chip 112, and the second electrical connection terminal 124 is coupled to the second wire VIN2 and the first control chip 112. The second control chip 114 is communicatively connected to the first control chip 112. The control module is selectively used to: generate a composite signal S3 that intermittently emits a reset signal S4; or generate a communication command signal S1 that has a constant-on command C1, and then generate a drive signal S2. For example, when the composite signal S3 meets the signal condition, the control module 102 can intermittently generate the reset signal S4. Here, the first control chip 112 can drive the second light-emitting diode 109 according to the communication command signal S1. The second control chip 114 can intermittently reset the preset control timing CT according to the reset signal S4 to drive the third light-emitting diode 110 to remain constantly lit. When the synthesized signal S3 does not meet the signal conditions, the control module 102 can generate a communication command signal S1 with a constant-on command C1. Here, the first control chip 112 can drive the second light-emitting diode 109 to remain constantly lit according to the constant-on command C1. The second control chip 114 can drive the third light-emitting diode 110 to modulate light emission according to the preset control timing CT. Accordingly, when the control module 102 wants to execute a complex light emission mode, the first control chip 112 can control the second light-emitting diode 109 to remain constantly lit, and only use the third light-emitting diode 110 to modulate light emission. This reduces the complexity of the synthesized signal S3 and avoids abnormal flickering of the first light emission.

[0105] In summary, in some embodiments, the multi-modulation light string 100 can selectively transmit the communication command signal S1 and the reset signal S4 to the drive signal S2 via the control module 102 to generate a composite signal S3, which is then output to the first conductor VIN1 and the second conductor VIN2. When the instruction of the communication command signal S1 is too complex and does not meet the signal conditions (signal conditions include: the total duration of these low-level bits does not exceed a first time threshold, and the number of these low-level bits is not less than 10; or the number of these low-level bits is less than 10, and the duration of each low-level bit does not exceed a second time threshold), the control module 102 can control the first control chip 112 not to perform the light-emitting mode, and only drive a portion of the light-emitting diode group 108 (which may refer to the second light-emitting diode 109) to be constantly lit or constantly dark. Then, the control module 102 controls the second control chip 114 to drive another portion of the light-emitting diode group 108 (which may refer to the third light-emitting diode 110) according to the preset control timing CT corresponding to the specified light-emitting mode, so as to replace the first control chip 112 in performing the specified light-emitting mode. Accordingly, the first light-emitting diode 104 will not be interfered with by the communication command signal S1 and will not cause abnormal flickering (for example, the first light-emitting diode 104 will cause irregular flickering or unexpected brightness reduction).

[0106] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
