[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] It should be understood that in the description of a utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0016] The LED strip controller disclosed in this utility model has a microcontroller unit (MCU) that integrates a Bluetooth communication module to enable wireless communication with external devices. Compared with other communication methods such as network cable connection or 4G module, it can reduce product costs (including material costs and maintenance costs) while maintaining the convenience of product installation and maintenance.

[0017] See Figure 1 As shown, in some embodiments, the LED light strip controller includes a microcontroller 10 with an integrated Bluetooth communication module, a first memory 20 connected to the microcontroller 10 for storing programs to be played, and at least one signal output interface 30 connected to the microcontroller 10 for connecting to the LED light strip. The microcontroller 10 communicates with external devices through the Bluetooth communication module to obtain control commands and firmware upgrade data.

[0018] Preferably, the first storage device 20 can be a flash memory such as a solid-state drive or a flash memory card. Of course, in other embodiments, other types of non-volatile memory can also be used.

[0019] In some embodiments, the LED strip controller further includes a second memory 40 connected to the microcontroller 10 for storing default programs. When the LED strip controller is powered on but no program is selected, the default program stored in the second memory 40 is played. Preferably, the second memory 40 can be a Flash memory such as a solid-state drive or a flash memory card. However, in other embodiments, other types of non-volatile memory can also be used.

[0020] Preferably, the signal output interface 30 is an interface that supports both DMX and TTL signals to meet the usage requirements of different types of LED strips. In the embodiment shown in the accompanying drawings, the LED strip controller is provided with two signal output interfaces 30. Of course, in other embodiments, more or fewer signal output interfaces may be provided.

[0021] Referring to the accompanying drawings, in this embodiment, the LED light strip controller further includes a power input interface 50 connected to the microcontroller 10 for connecting to an external power source to obtain the operating power of the LED light strip controller.

[0022] Referring to the accompanying drawings, in this embodiment, the LED light strip controller further includes an LED indicator 60 connected to the microcontroller 10 to display the working status of the LED light strip controller, making it convenient for staff to check the working status of the LED light strip controller.

[0023] First, the Bluetooth communication module is initialized by calling the Bluetooth library provided by the manufacturer. During this process, the Bluetooth communication module is set to slave mode to facilitate connection with external Bluetooth devices. At the same time, appropriate transmit power and power consumption are configured according to the application scenario requirements to optimize communication performance.

[0024] After initialization, the LED strip controller enters a connection waiting state, ready to establish a Bluetooth communication connection with external devices such as mobile phones.

[0025] When the LED strip controller is powered on and no program is selected to play, it will play the built-in default program by default.

[0026] After establishing a Bluetooth connection, the system determines whether a firmware upgrade is needed. If so, it receives firmware upgrade data from the external device to upgrade the LED strip controller before proceeding to the initialization step. If not, the user can send commands to the LED strip controller via a mini-program on the external device. The LED strip controller then performs corresponding actions based on the received commands, such as switching playback programs, adjusting playback modes, or setting timed tasks.

[0027] After the Bluetooth connection is disconnected, the Bluetooth communication module enters sleep mode to reduce power consumption and waits to be woken up again.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Those skilled in the art can make various equivalent changes and improvements based on the above embodiments. All equivalent changes or modifications made within the scope of the claims should fall within the protection scope of the present utility model.
