[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0042] To address the problems in the existing technology, this utility model proposes a wirelessly controlled moving head light to achieve remote wireless control of the light fixture. The wirelessly controlled moving head light is described below, as follows: Figure 1 As shown, including but not limited to the following modules:

[0043] Button power-on module, boost power supply module, control module, attitude sensing module, wireless communication module;

[0044] The button power-on module is used to start the power supply;

[0045] The boost power supply module is used to increase the voltage of the power supply to the required operating voltage;

[0046] The wireless communication module is used to receive user control commands and also to transmit lighting control signals to adjust the movement direction of the lighting fixtures.

[0047] The attitude sensing module is used to detect changes in the attitude of the device;

[0048] The control module is used to generate lighting control signals based on the user control commands and the posture changes.

[0049] The wireless communication module is connected to the control module, and the attitude sensing module is connected to the control module.

[0050] Specifically, the button power-on module

[0051] The button power-on module is used to start the power system and activate the circuit's operating state. This module includes a tactile button (such as SW1) connected to the power management circuit. When the user presses the button, the battery voltage is transferred to transistor Q3 through resistor R6. After transistor Q3 turns on, it triggers a change in the gate level of MOSFET Q1, causing MOSFET Q1 to turn on and thus activating the power module to provide voltage to subsequent circuits.

[0052] Boost power supply module

[0053] The boost converter module is used to increase the voltage supplied by the battery (e.g., 3.7V) to the required operating voltage (e.g., 5V). In this embodiment, the boost converter module uses a high-efficiency synchronous boost converter (e.g., SY7069ADC). When the battery voltage is input to the boost converter module, after passing through filter capacitors (e.g., C9, C4, C5), the boost converter module increases the battery voltage to the set output voltage (e.g., 5V). This output voltage is further filtered by capacitors C6 and C7, and then output to the subsequent voltage regulator module through a diode (e.g., D1). The boost converter module also includes a feedback loop to stabilize the output voltage and ensure stable system operation.

[0054] Control module

[0055] The control module is the core component of the wirelessly controlled moving head light, mainly composed of a microcontroller (such as an ARM 32-bit M4 core microcontroller). In this embodiment, the control module processes signals from the wireless communication module and the attitude sensing module to generate control signals for the light fixture, thereby achieving motion control. Specifically, the control module receives control commands sent by the user through the wireless communication module and, combined with the device attitude information fed back by the attitude sensing module, calculates the direction and angle of the light fixture's movement.

[0056] The control module communicates with other modules through interfaces such as GPIO, SPI, or I2C. For example, the control module can perform bidirectional data transmission with the wireless communication module through the SPI interface, or exchange data with the attitude sensing module (such as a three-axis accelerometer, gyroscope, etc.) through the I2C interface, thereby achieving precise control of the device.

[0057] Attitude sensing module

[0058] The attitude sensing module detects changes in the device's attitude, ensuring the moving head light's direction matches the user's control requirements. This module includes sensors such as a three-axis accelerometer, a three-axis gyroscope, and a three-axis magnetometer (e.g., LSM6DS3TR and LIS2MDLTR), and communicates with the control module via an I2C interface. The accelerometer and gyroscope detect the device's motion state and angular velocity, while the magnetometer provides directional information.

[0059] The attitude sensing module collects real-time data on the device's angular velocity, acceleration, and magnetic field to calculate the device's Euler angles, and then deduce the lamp's direction of motion. The control module adjusts the lamp's angle and direction of motion based on this data to ensure precise positioning and stability.

[0060] Wireless communication module

[0061] The wireless communication module receives remote control commands from the user and transmits control signals for the lighting fixture. This module employs radio frequency communication technology (such as LoRa wireless communication modules) to support long-distance data transmission. The wireless communication module communicates bidirectionally with the control module via an SPI interface, receiving commands from the user and sending lighting fixture motion control signals to the main lighting chip.

[0062] Specifically, the wireless communication module receives user control commands via a radio frequency transceiver (such as the E220-400M22S RF module). These commands include the direction and angle of the light fixture's movement. The control module generates corresponding motion control signals based on the received commands and transmits these signals to the light fixture via the wireless communication module. The RF module's function is to extend the operating range and increase the communication distance, reaching a maximum of 5500 meters.

[0063] Connection and coordinated operation of control modules

[0064] In this embodiment, all modules work together through a reasonable circuit connection. The wireless communication module is connected to the control module, receiving and sending control signals wirelessly; the attitude sensing module is connected to the control module, providing real-time feedback on the device's motion status. The control module combines the control commands from the wireless communication module and the attitude data from the attitude sensing module to generate the final lighting control signals. These control signals are transmitted to the inside of the lighting fixture by the wireless communication module, thereby controlling the direction and angle of the lighting fixture's movement.

[0065] Overall, the button power-on module provides the function of starting the power supply, the boost power supply module provides a stable operating voltage for the system, the posture sensing module provides accurate motion data, the control module controls the lamp based on this information, and the wireless communication module is responsible for receiving and transmitting remote control commands. Through the coordinated work of these modules, this wirelessly controlled moving head lamp can accurately control the movement direction of the lamp according to user commands and achieve efficient and stable operation.

The VCC input from the USB Type-C interface (USB1) is filtered by capacitors C2 and C3 before being supplied to chip U2. Pin 5 (PROG) of U2 is used to monitor and control the charging current, which is set by resistor R9 using the formula IBAT = (VPROG / R9) * 1000, with a set current of 100mA. The battery voltage (BATIN) is divided by resistors R1 and R2 to obtain the ADC_BAT signal, which is connected to the microcontroller U4 (AT32F413CBT7). When the battery voltage is below 2.5V, the microcontroller detects a low level in the ADC_BAT signal and determines that the battery needs charging. Pin 1 (CHAG) of chip U2 outputs the charging status. When the battery voltage is below 4.2V, CHAG is low and LED2 is lit; when the battery is fully charged to 4.2V, CHAG becomes high impedance and LED2 is off, indicating that charging is complete. Pin 3 (BAT) of U2 supplies power to battery BAT1 after filtering through capacitors C10 and C8.

Combining data from these two chips, the microcontroller can calculate the lamp's direction of motion and Euler angles.

[0076] A triaxial accelerometer is used to detect the acceleration of lighting fixtures;

[0077] A triaxial magnetometer is used to detect the magnetic field of lamps.

[0078] Specifically, refer to Figure 4 The system utilizes a low-power, high-performance triaxial magnetometer Hall sensor chip U6 (LIS2MDLTR) and a triaxial gyroscope-accelerometer chip U7 (LSM6DS3TR). U6 communicates with the microcontroller U4 via an I2C interface to transmit magnetic field data; U7 communicates with the microcontroller U4 via an I2C interface to transmit acceleration and angular velocity data. The microcontroller combines the data from both to generate the output of a nine-axis sensor (including the triaxial gyroscope, triaxial accelerometer, and triaxial magnetometer), calculates the lamp head's motion direction based on Euler angles, and generates the corresponding X / Y axis motion data.

[0079] As a further optional embodiment, the wireless communication module includes an E220-400M22S radio frequency module;

[0080] The E220-400M22S RF module and the M4 core microcontroller communicate bidirectionally via an SPI interface.

[0081] The E220-400M22S RF module is connected to the corresponding pins of the M4 core microcontroller via the MISO, MOSI, SCK, and NSS pins of the SPI interface.

[0082] Specifically, refer to Figure 5 The LoRa wireless module U5 (E220-400M22S) uses the LLCC68 RF chip and is suitable for the 433MHz and 470MHz frequency bands. The module communicates with the microcontroller U4 (AT32F413CBT7) via an SPI interface (pin 16_SPI2_MISO, pin 17_SPI2_MOSI, pin 18_SPI2_SCK, pin 19_SPI2_NSS). The microcontroller also controls the transmit and receive switches of the RF module via serial port pins, and pins 19 and 18 control the reset and status ports. Through the LoRa RF module, the device can achieve long-distance (maximum 5500m) communication, transmitting the lamp head's motion data to the RF module inside the lamp, automatically adjusting the lamp's direction of movement.

[0089] One end of the tactile switch is connected to the positive terminal of the power supply, and the other end is connected to the base of the transistor, so that the battery voltage enters the boost power supply module through the field-effect transistor.

[0090] Specifically, refer to Figure 6The power-on button is pressed by lightly touching button SW1. When SW1 is pressed, the battery voltage is transferred to resistor R6, activating transistor Q3 and turning it on. At this time, the gate (G) of MOSFET Q1 is low, Q1 conducts, and the battery voltage (BATIN) is input to the enable pin EN of boost converter U1 (SY7069ADC), starting the boost operation. The battery voltage is filtered by capacitors C9, C4, and C5 before being supplied to U1. Inductor L1 stores energy, and U1 provides voltage feedback through pins 1 (FB) and 4 (OUT), setting the output voltage VOUT = 1.2 * (1 + R5 / R8). After filtering by capacitors C6 and C7, a 5V voltage (OUT_5V) is output through diode D1 to prevent reverse current. After being filtered by capacitors C15 and C11, the OUT_5V is converted to 3.3V by the voltage regulator chip U3 (AMS117-3.3V), and then filtered by capacitors C16, C12, C14 and C13 before finally being supplied to the microcontroller and other circuits.
