[0030] Specifically, the main body 1 of the lamp is the main mounting structure, including electrical components and a housing; a Hall angle position sensor chip 3 is installed on one side to detect the polarity direction of the magnet; accessories 2 are used to expand the lamp's functions, such as light covers, diffusers, brackets, or other additional modules; a radially magnetized magnet 4 is installed on the side of accessory 2 near the main body 1, with a clear magnetization direction, providing stable polarity information; the Hall angle position sensor chip 3 is installed on the main body 1 to detect the N pole orientation of the radially magnetized magnet 4 in real time; the chip can convert the detection result into a signal and transmit it to the control system; the radially magnetized magnet 4 is magnetized into a radially polarized form through a magnetization process; different types of accessories 2 can be identified by different magnet polarity directions (such as N pole facing outward or S pole facing outward); one or more radially magnetized magnets 4 can be set, and the number of Hall angle position sensor chips 3 can also be set accordingly.

[0031] Furthermore, the lamp body 1 is equipped with a main control chip; and the Hall angle position sensor chip 3 is electrically connected to the main control chip; and the lamp body 1 is equipped with a display module that is electrically connected to the main control chip; after the Hall angle position sensor chip 3 detects the N-position orientation of the radial magnetized magnet 4, the signal is fed back to the main control chip, thereby the main control chip controls the display module to display the type of accessory 2.

[0032] Specifically, the main control chip is the core of the lighting system, responsible for signal processing, logic judgment, and control of the display module. The main control chip is electrically connected to the Hall angle position sensor chip 3 to receive the sensor's detection signal. Based on the magnetic pole direction signal fed back by the Hall chip, the current accessory 2 type is determined by an algorithm. The display module is set outside the main body 1 of the lighting fixture to display the accessory 2 type information in real time. It is electrically connected to the main control chip and controlled by the main control chip. Based on the recognition result, it outputs the accessory 2 type. After the Hall sensor detects the orientation of the N pole of the radially magnetized magnet 4, it sends the magnetic field direction signal to the main control chip. The main control chip analyzes the signal and matches it with the corresponding accessory 2 type database. After the matching is completed, the main control chip controls the display module to output the current accessory 2 type (such as text, icon, etc.).

[0035] Furthermore, the N-pole orientation of the radially magnetized magnet 4 has at least four orientations: N-pole facing up, N-pole facing down, N-pole facing left, and N-pole facing right.

[0036] Specifically, during the production of accessory 2, different accessories 2 will have magnets installed in different directions, so that they can provide four different polarity directions: N-pole upward, N-pole downward, N-pole left, and N-pole right. Each polarity direction corresponds to one accessory 2 type. The Hall angle sensor can accurately detect the direction of the radial magnetic field and feed the direction information back to the main control chip. The main control chip receives the angle direction signal from the Hall sensor. Based on the detected magnetic field direction, it matches it with the pre-set accessory 2 type database to determine the currently installed accessory 2 type.

[0037] Furthermore, accessory 2 is one of the following: 15-degree diffuser, 30-degree diffuser, 45-degree diffuser, or 60-degree diffuser.

[0040] Specifically, as an example, the main control chip U1 can be model APM32F103RCT6; the Hall angle position sensor chip U3 can be model MT6701CT-STD.

[0041] Furthermore, a crystal oscillator circuit is provided to provide a clock source for the main control chip U1; and the crystal oscillator circuit includes an inductor L1, a resistor R8, and a capacitor C2 connected to the 5th pin of the main control chip U1; and the other end of capacitor C2 is connected to capacitor C5; and the other ends of capacitor C5, capacitor R8, and inductor L1 are all connected to the 6th pin of the main control chip U1.

[0042] Furthermore, a reset circuit is provided to ensure that the main control chip U1 is in a defined initial state when powered on; the reset circuit includes a resistor R10 connected to pin 28 of the main control chip U1, a resistor R11 connected to pin 60 of the main control chip U1, and the other end of the resistor R11 is grounded; a resistor R13 connected to pins 7, 32, 48, 64, 19, and 13 of the main control chip; and a capacitor C6 connected to pin 7 of the main control chip U1, and the other end of the capacitor C6 is grounded.

When the diffuser is installed, the main control chip reads the direction of the magnets through the Hall angle position sensor chip, thereby knowing the angle of the diffuser and realizing intelligent recognition and display.
