[0041] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0042] The following further elaborates on this application in conjunction with the accompanying drawings:

[0043] Embodiment 1

[0044] The embodiment of this application provides a light strip control device. Referring to Figure 1 as shown, the light strip control device is composed of multiple lighting control units. Each lighting control unit can send or receive lighting control signals, enabling the lighting control signals to be transmitted to each other among different lighting control units, realizing a decentralized lighting control mode, eliminating the settings of the host and slave machines in the traditional lighting linkage control system, simplifying the system configuration process, and improving the flexibility and scalability of the system.

[0045] Referring to Figure 2 as shown, each lighting control unit includes a microprocessor, a communication module, a timer, and an LED driver.

[0046] Specifically, the microprocessor is the core of each lighting control unit, controlling the real-time state conversion and lighting control signal processing of the lighting control unit. In this embodiment, a high-performance and low-power chip is adopted for the microprocessor to ensure fast and accurate state conversion.

[0047] The timing module is closely connected to the microprocessor and is used to set and control the time period of the real-time state conversion of the lighting control unit. An accurate timing circuit is assembled inside the timing module, which can accurately grasp the time period according to the preset program, thereby ensuring the smooth cycle conversion of the lighting control unit between the sending end state and the receiving end state.

[0048] The communication module transmits lighting control signals in the light strip control device. According to the real-time state of the lighting control unit, it flexibly transmits lighting control signals among the lighting control units and timely transmits these signals to the microprocessor for outputting corresponding lighting control instructions. In this embodiment, the anti-interference ability of the communication module is particularly enhanced to ensure the stability and accuracy of signal transmission.

[0049] The driving module executes lighting control instructions, receives instructions from the microprocessor, and accurately controls the display mode of the lights according to these instructions, ensuring the real-time and accurate presentation of the lighting effects.

[0050] Embodiment 2

[0051] Based on Embodiment 1, the functions of a light strip control device are further optimized in this embodiment.

[0052] Specifically, the real-time status of the lighting control unit includes the transmitter status and the receiver status. The flexible switching between these two statuses enables the lighting control unit to play a greater role in signal interaction. When initially powered on, the lighting control unit is set to the receiver status to ensure the stable startup of the system. After a set time period, the microprocessor will control the lighting control unit to switch from the receiver status to the transmitter status, thereby realizing the transmission of lighting control signals. When the lighting control unit is in the transmitter status, after another time period, the microprocessor will control it to switch back to the receiver status again, thus completing a complete status conversion cycle. Subsequently, every time a time period elapses, the microprocessor will control the lighting control unit to perform a status conversion, realizing the intelligent polling of the lighting control unit, ensuring that the lighting control unit can receive or send control signals in a timely manner, reducing communication conflicts, and enhancing the stability and response speed of the overall lighting control system.

[0053] Specifically, the timing module also includes a delay module. The function of this delay module is to generate a random waiting time after each time period ends to avoid possible communication conflicts. Through this mechanism, when multiple lighting control units need to transmit signals within the same time period, they will transmit at different time points, effectively preventing signal interference with each other.

[0054] Specifically, each lighting control unit also includes a check encoding module and a check decoding module. Both of these modules are connected to the communication module and are used to perform check encoding and decoding operations on the lighting control signals to be sent and received. By performing check encoding on the lighting control signals to be sent through the check encoding module, the integrity and accuracy of the signals during transmission can be ensured. The check decoding module is used to perform check decoding on the received lighting control signals to verify the integrity and accuracy of the signals, improve the reliability and anti-interference ability of signal transmission, and ensure the stable realization of lighting control effects.

[0055] Embodiment 3

[0056] For the light strip linkage control device provided in the embodiments of the present application, refer to Figure 3 as shown, and its working process is as follows:

[0057] After the system is powered on and starts up, the microprocessors of all lighting control units set the wireless communication module to the receiving state and trigger a 50MS countdown of the timing module. This is the initial preparation stage, laying the foundation for subsequent status conversion and information transmission.

[0058] When the 50MS countdown ends, the microprocessor will switch the lighting control unit (prototype n) to the transmitter state, send the lighting control signal of prototype n through the wireless communication module, that is, parameters such as the color temperature and brightness of prototype n, and refresh the 50MS countdown. After another 50MS, the microprocessor will switch prototype n to the receiver state.

[0059] When the 50MS countdown has not ended, prototype n remains in the receiver state and continuously determines whether data is received. When data is received, the microprocessor will switch the lighting control unit (prototype n) to the transmitter state and send the lighting control signal of prototype n through the wireless communication module again; when data is not received continuously, prototype n continues to maintain the receiver state and waits for the next state transition. Such a cyclic process enables each lighting control unit to continuously receive and send information, ensuring the real-time performance and linkage of the entire system.

[0060] In Embodiments 1 to 3, the communication module can adopt communication protocols such as Zigbee, Wi-Fi, or Bluetooth for signal transmission. This flexible communication method makes the strip light control device of the present invention have wider applicability and compatibility.

[0061] Embodiment 4

[0062] Based on Embodiment 1, the drive module in this embodiment not only receives the lighting control instructions from the microprocessor but also controls the specific lighting display mode according to the instructions. These display modes can include various effects such as brightness adjustment, color transformation, and flicker frequency adjustment. Through the refined control of the drive module, more diverse lighting display effects can be achieved. Users can flexibly adjust the display effects of the strip lights according to their own needs to meet different scenario requirements.

[0063] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. In practical applications, the above embodiments can be appropriately modified and adjusted according to specific requirements. For example, the time period length of the state transition can be adjusted, the type of communication protocol can be modified, or other functional modules can be added. All equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
