It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0025] Example 1

[0026] Figure 1A is a structural diagram of a driver chip provided in Example 1 of the present application, which includes a power management component 100 and a driver management component 200; the power management component 100 includes a power interface module 101, a rectifier and filter module 102, and an energy storage module 103 connected in sequence; the power management component 100 is connected to the driver management component 200, and is configured to obtain the electrical energy output by the power supply through the power interface module 101, and to supply power to the driver management component 200 through the rectifier and filter module 102 or the energy storage module 103; wherein, the power interface module 101 is connected to the power supply through a non-polarity wiring method.

[0027] As shown in Figure 1B, the power interface module 101 includes two power interfaces 111. Each power interface 111 is connected to a power source via unmarked wires of the same color. This connects the power source and the power management component 100 in series, allowing the driver chip to operate normally under both positive and negative voltages. This also avoids safety hazards caused by incorrect power connection. The rectifier and filter module 102 rectifies the sinusoidal AC power input through an internal rectifier circuit and outputs pulsating DC power. However, since this DC power also contains AC components, it is necessary to further filter the pulsed DC power through an internal filter circuit to filter out the AC components.

[0028] The rectifier circuit can perform rectification processing through a diode; the filter circuit can be composed of a capacitor element and an inductor element, and the filtering processing is performed through a capacitor filter circuit, an inductor filter circuit, and a composite filter circuit; optionally, in this application, the structure of the rectifier circuit and the filter circuit is not limited. In addition, because the operating power of the driver chip is relatively low, the rectifier and filter module 102 usually needs to step down the AC power before performing the rectification processing, and after the filtering processing is completed, stabilize the DC power to meet the power requirements of multiple functional components in the driver chip.

[0029] The energy storage module 103 serves as an energy storage element in the power management component 100. When the power supply is normally supplied, the rectifier and filter module 102 outputs the output DC power to the drive management component 200 to meet the power supply requirements of the drive management component 200. At the same time, the DC power is also output to the energy storage module 103. The energy storage module 103 stores electrical energy through internal capacitors or other energy storage elements. When the power supply transmits data by changing the voltage direction, the rectifier and filter module 102 no longer supplies power to the drive management component 200. Instead, the energy storage module 103 serves as a power supply device to transmit the stored electrical energy to the drive management component 200 to provide the drive management component 200 with the electrical energy required for operation.

[0030] The driver management component 200 includes a power sampling module 201, a logic control module 202, and a driver execution module 203, which are connected in sequence. The power sampling module 201 is connected to the power interface module 101 and is configured to obtain the voltage direction of the power supply. The logic control module 202 is connected to the power management component 200 and is configured to determine the target driver interface to be controlled and the target lighting mode based on the proportional relationship between the positive voltage duration and the negative voltage duration. The driver execution module 203 is configured to illuminate the target device based on the target lighting mode via the target driver interface.

[0031] The power sampling module 201 is connected to any one of the two power interfaces 111 mentioned above and is configured to detect the voltage direction of the power supply. For example, the voltage of the current flowing from the current power interface to the other power interface is defined as a negative voltage, and the voltage of the current flowing from the other power interface to the current power interface is defined as a positive voltage.

[0032] The logic control module 202 determines the value of the current data bit based on the proportional relationship between the duration of the positive voltage and the duration of the negative voltage within a data detection cycle. For example, if the ratio between the duration of the positive voltage and the duration of the negative voltage is one to two, the current data bit is determined to be a value of 1; if the ratio between the duration of the positive voltage and the duration of the negative voltage is two to one, the current data bit is determined to be a value of 0. In this way, the value of a data bit is obtained within a data detection cycle. The multiple data bits obtained through continuous data detection cycles constitute the device control instructions.

[0033] The driver execution module 203 can be connected to one or more driver interfaces 204, each of which is connected to a device (for example, an LED device); in the present application, the same number of data bits can be assigned to each device to be controlled, for example, 8 bits are used to represent 256 brightness levels (i.e., 0 to 255 levels); 4 bits are used to represent 8 different colors (for example, red, orange, yellow, green, cyan, blue, purple and white); 1 bit is used to represent the state (i.e., always on or flashing); thus, 13 bits can be used to represent the control instructions of a device in binary.

[0034] If the driver execution module 203 is connected to a device via each of the three driver interfaces 204, then the lighting mode of each device can be determined by sequentially obtaining a control instruction consisting of 39 data bits (i.e., 13×3=39). The driver management component 200 then controls the lighting modes of multiple devices accordingly. Furthermore, multiple bits can be used to represent the identification information of different devices. For example, if the four devices described above can be distinguished using only two bits, then 15 bits (i.e., 13+2=15) can be used to achieve targeted control of the target device. This avoids redundant control of unneeded devices and reduces the number of data bits in the transmitted signal.

[0035] Optionally, in the present application, the power sampling module 201 includes a direction sampling unit and a value sampling unit; the direction sampling unit is configured to obtain the voltage direction of the power supply; the value sampling unit is configured to obtain the voltage value of the power supply; the logic control module 202 is configured to determine the target drive interface to be controlled and the target lighting mode based on the proportional relationship between the positive voltage duration and the negative voltage duration, as well as the positive voltage value and the negative voltage value.

[0036] During a data detection cycle, the power sampling module 201 can detect the direction of the power supply voltage through the direction sampling unit and the power supply voltage value through the value sampling unit, thereby obtaining the proportional relationship between the positive voltage duration and the negative voltage duration, as well as the positive voltage value and the negative voltage value. The positive voltage value and the negative voltage value can be used to represent the identification information of the device to be controlled, that is, the identification information of the driver interface 204 to be controlled. For example, as shown in FIG1C , when the positive voltage value and the negative voltage value are 1V and -1V, respectively, it indicates that device No. 1 is controlled by driver interface No. 1; when the positive voltage value and the negative voltage value are 2V and -2V, respectively, it indicates that device No. 1 is controlled by driver interface No. 2. In FIG1C , the proportional relationship between the positive voltage duration and the negative voltage duration is actually the same for both devices, indicating that device No. 1 and device No. 2 are illuminated in the same lighting mode. However, the difference in voltage value can accurately distinguish whether the current device control instruction is for device No. 1 or device No. 2. Thus, directional transmission of the target device is achieved without increasing the number of data bits, thereby improving data transmission efficiency.

[0037] Optionally, in the present application, the driver management component 200 also includes an image drawing module 205; the image drawing module 205 is connected to the logic control module 202 and is configured to draw a voltage waveform according to the voltage direction; the logic control module 202 is configured to determine the target drive interface to be controlled and the target lighting mode according to the voltage waveform.

[0038] After obtaining the voltage direction of the power supply collected by the power sampling module 201, the logic control module 202 sends the above voltage direction to the image drawing module 205. The image drawing module 205 draws a waveform diagram of the voltage direction within a data detection cycle. The logic control module 202 compares the above waveform diagram with multiple pre-stored waveform diagrams to determine the value corresponding to the current waveform diagram. For example, if data is transmitted in binary mode, only two waveform diagrams need to be pre-stored. If data is transmitted in decimal mode, then ten waveform diagrams need to be pre-stored accordingly.

[0039] The logic control module 202 can obtain the numerical value obtained in the current data detection cycle based on the comparison result of the above-mentioned waveform diagram, and then compose the numerical values ​​obtained in multiple consecutive data detection cycles into a device control instruction, and then determine the target drive interface and target lighting method to be controlled according to the device control instruction. The voltage waveform diagram drawn by the image drawing module 205 not only makes the transmitted data more intuitive, but also improves the data transmission accuracy and the transmission accuracy of the device control instruction through the similarity comparison of the waveform diagram.

[0040] Optionally, in the present application, the driver management component 200 further includes a reference clock module 206; the reference clock module 206 is connected to the logic control module 202 and configured to provide a reference clock signal to the logic control module 202. The logic control module 202 may use one or more reference clock signals as a data detection cycle and determine the detection time of each data detection cycle based on the reference clock signal provided by the reference clock module 206, thereby ensuring the time consistency of each data detection cycle and improving the accuracy of obtaining the transmitted data.

[0041] Optionally, in the present application, the drive management component 200 also includes a brightness detection module 207; the brightness detection module 207 is connected to the logic control module 202 and is configured to detect the ambient brightness; the logic control module 202 is configured to determine the target drive interface to be controlled and the target lighting method based on the ambient brightness transmitted by the brightness detection module 207.

[0042] The brightness detection module 207 may include functional elements such as an illuminometer, a photometer, and a radiometer. The above functional elements measure the brightness of the environment where the driver chip is located by measuring light intensity, light source brightness, or light source radiation energy. The logic control module 202 determines the number of target devices and the lighting method of each target device based on the ambient brightness, thereby realizing automatic adjustment of the device lighting status based on the ambient brightness and improving the adjustment accuracy of the device lighting status.

[0043] In this application, the power management component can not only supply power to the drive management component but also realize data transmission based on the voltage change of the power supply through the power interface module, the rectifier and filter module and the energy storage module. The drive management component realizes device brightness control based on power transmission data through the power sampling module, the logic control module and the drive execution module. In this way, without increasing the hardware cost of the driver chip, the effective transmission of device control instructions is realized, the hardware structure of the driver chip is simplified, and the management complexity of the functional modules inside the driver chip is reduced.

[0044] Example 2

[0045] FIG2 is a structural diagram of a driver chip provided in a second embodiment of the present application. In the driver chip, the driver management component 200 further includes an identification storage module 208 . The identification storage module 208 is connected to the logic control module 202 and is configured to store identification information of the current driver chip.

[0046] When the power supply is connected to multiple driver chips at the same time, it may issue device control instructions to different driver chips in a polling manner, or it may only issue device control instructions to some of the driver chips according to user needs. In this case, the power supply first issues the identification information of the target driver chip to be controlled by changing the voltage direction. The logic control module 202 first determines the identification information of the target driver chip to be controlled based on the proportional relationship between the positive voltage duration and the negative voltage duration, and compares the identification information of the target driver chip with the identification information of the current driver chip.

[0047] If the identification information of the target driver chip is determined to be different from the identification information of the current driver chip, it indicates that the current driver chip is not the controlled chip and the device control instruction issued is not related to the current driver chip. In this case, the logic control module 202 will not continue to obtain subsequent device control instructions; the power sampling module 201 will continue to detect the direction of the power supply voltage. If the identification information of the target driver chip is determined to be the same as the identification information of the current driver chip, it indicates that the current driver chip is the controlled chip and the device control instruction issued is related to the current driver chip.

[0048] Logic control module 202, through power sampling module 201, continues to acquire the proportional relationship between the positive voltage duration and the negative voltage duration, and determines the target driver interface to be controlled and the target lighting mode based on this proportional relationship. This allows driver management component 200 to identify the identification information of the target driver chip and determine whether to execute subsequent device control instructions, thus achieving targeted control of a specific device under a specific driver chip and improving the convenience and accuracy of the driver chip's control of the device's lighting status.

[0049] In this application, the identification storage module stores the identification information of the current driver chip, and the logic control module determines the identification information of the target driver chip to be controlled based on the proportional relationship between the positive voltage duration and the negative voltage duration. When it is determined that the identification information of the target driver chip is the same as the identification information of the current driver chip, the logic control module continues to determine the target driver interface to be controlled and the target lighting method based on the proportional relationship between the positive voltage duration and the negative voltage duration, thereby realizing directional control of the specified device under a specific driver chip, and improving the convenience and accuracy of the driver chip controlling the lighting status of the device.

[0050] Example 3

[0051] Figure 3 is a structural diagram of a driver chip provided in Example 3 of the present application. The driver management component 200 of the driver chip also includes a photosensor 209; the photosensor 209 is connected to the logic control module 202 and is configured to transmit an electrical signal to the logic control module 202 based on the detected light signal; the logic control module 202 is also configured to determine the identification information of the current driver chip based on the electrical signal transmitted by the photosensor 209, and store the identification information of the current driver chip in the identification storage module 208.

[0052] The photosensor 209 is a sensitive device that has the function of converting external light signals. It uses photosensors to convert light signals into electrical signals. When it is necessary to configure or update the identification information of the driver chip, the external device can transmit the identification information by emitting bright light of different intensities in multiple consecutive detection cycles. When the logic control module 202 obtains the electrical signal transmitted by the photosensor 209, it can determine the light intensity based on the voltage or current intensity, and then compare the light intensity with the preset light threshold to determine whether the value of the current data bit is 0 or 1. Multiple consecutive data bits constitute the identification information of the driver chip.

[0053] As shown in Figure 3, the driver management component 200 of the driver chip also includes a vibration sensor 210; the vibration sensor is connected to the logic control module 202 and is configured to transmit an electrical signal to the logic control module 202 based on the detected vibration signal; the logic control module 202 is also configured to determine the identification information of the current driver chip based on the electrical signal transmitted by the vibration sensor 210, and store the identification information of the current driver chip in the identification storage module 208.

[0054] The vibration sensor 210 is a device that has the function of detecting external impact force. It converts the vibration signal into an electrical signal through mechanical measurement, optical measurement or electrical measurement. When it is necessary to configure or update the identification information of the driver chip, the external device can transmit the identification information by emitting vibrations of different intensities in multiple consecutive detection cycles. When the logic control module 202 obtains the electrical signal transmitted by the vibration sensor 210, it can determine the vibration intensity based on the voltage or current intensity, and then compare the vibration intensity with the preset vibration threshold to determine whether the value of the current data bit is 0 or 1. The multiple consecutive data bits constitute the identification information of the driver chip.

[0055] As shown in Figure 3, the driver management component 200 also includes a temperature sensor 211; the temperature sensor 211 is connected to the logic control module 202 and is configured to transmit an electrical signal to the logic control module 202 based on the detected temperature signal; the logic control module 202 is also configured to determine the identification information of the current driver chip based on the electrical signal transmitted by the temperature sensor 211, and store the identification information of the current driver chip in the identification storage module 208.

[0056] The temperature sensor 211 is a device that senses temperature and converts it into a usable output signal. It converts temperature changes into electrical signals through contact or non-contact methods. When the identification information of the driver chip needs to be configured or updated, the external device can transmit the identification information by changing the temperature within multiple consecutive detection cycles. When the logic control module 202 obtains the electrical signal transmitted by the temperature sensor 211, it can determine the actual temperature based on the voltage or current intensity, and then compare the actual temperature with the preset temperature threshold to determine whether the value of the current data bit is 0 or 1. Multiple consecutive data bits constitute the identification information of the driver chip.

[0057] As shown in Figure 3, the drive management component 200 also includes a Hall sensor 212; the Hall sensor 212 is connected to the logic control module 202 and is configured to transmit an electrical signal to the logic control module 202 based on the detected magnetic field signal; the logic control module 202 is also configured to determine the identification information of the current driver chip based on the electrical signal transmitted by the Hall sensor 212, and store the identification information of the current driver chip in the identification storage module 208.

[0058] The Hall sensor 212 is a magnetic field sensor based on the Hall effect, which converts a changing magnetic field into a change in output voltage. When the identification information of the driver chip needs to be configured or updated, the external device can transmit the identification information by changing the magnetic field size or the presence or absence of a magnetic field in multiple consecutive detection cycles. When the logic control module 202 obtains the electrical signal transmitted by the Hall sensor 212, it can determine the magnetic field strength or the presence or absence of a magnetic field based on the voltage or current strength, and then compare the magnetic field strength with the preset magnetic field threshold to determine whether the value of the current data bit is 0 or 1, or directly determine the value of the current data bit as 0 or 1 based on the presence or absence of a magnetic field. Multiple consecutive data bits constitute the identification information of the driver chip.

[0059] In this application, by configuring a photosensor, a vibration sensor, a temperature sensor and a Hall sensor in the driver chip, the configuration and update of the driver chip identification information are realized through various forms such as light changes, vibration changes, temperature changes and magnetic field changes, thereby ensuring the orderly transmission of device control instructions.
