And the sensing module is used for sensing the action of the key moving module and sending signals of linear movement and rotation angle to the control module.

And the control module processes the signals of the linear movement and the rotation angle transmitted by the induction module and sends a control instruction to the main circuit. As shown in fig. 1, the control module is a single chip microcomputer 3, and the model of the single chip microcomputer is STM8S003F3 in this embodiment, as shown in fig. 3, but the model of the single chip microcomputer is not limited thereto in practical application.

In this embodiment, the linear movement includes pressing a release button in the Z-axis direction to move the magnet 2 closer to or away from the 3D magnetic sensor 1.

In some embodiments, the linear movement may also include linear movement in any direction along the XY plane (i.e., a plane perpendicular to the Z axis), enabling movement of the magnet 2 in any direction on the XY plane.

And the main circuit 4 is used for receiving the control instruction sent by the control module and driving the LED module to emit light for illumination.

As shown in fig. 1, the sensing module is a 3D magnetic sensor 1. The 3D magnetic sensor 1 is located just below the magnet 2 of the key moving module, spaced apart by less than 15mm, and has no contact with the magnet 2 of the key moving module, as shown in fig. 2. The key moving module is a key switch with 360-degree rotation, linear movement and pressing functions, and the magnet 2 is fixed in the center of the key. When the key moving module presses, rotates or linearly moves, the position of the magnet 2 relative to the 3D magnetic sensor 1 changes, and the 3D magnetic sensor 1 can sense the change of the position of the magnet 2.

As shown in fig. 1 and 4, the main circuit 4 includes a PNP transistor Q1A, an emitter of the PNP transistor Q1A is connected to the battery positive electrode BAT +, a base of the PNP transistor Q1A is connected to the control module through a resistor R23, a resistor R4 is connected between the emitter and the base of the PNP transistor Q1A, a collector of the PNP transistor Q1A is connected to the LED1-8 through resistors R1, R3, R5, and R7, respectively, wherein the resistor R1 is connected to the LED1-2, the resistor R3 is connected to the LED3-4, the resistor R5 is connected to the LED5-6, and the resistor R7 is connected to the LED 7-8.

As shown in fig. 5, the power module is a power voltage stabilizing chip, and can output different voltages, such as 3.3V or 5V, according to different types of the single chip microcomputer.

The working principle is as follows:

the key moving module is used for switching the lighting modes of the lighting equipment, a user can select to press down or rotate the key moving module according to needs, the 3D magnetic sensor senses the actions and transmits sensing signals to the single chip microcomputer so as to sequentially control the main circuit and the LED module, and therefore switching of different lighting modes such as starting, shutting down, gear shifting, stepless dimming of brightness and the like is achieved. The sensing principle of the 3D magnetic sensor for different operation actions of the key moving module is as follows: when the key is pressed down, the magnet is closer to the 3D magnetic sensor, the detected magnetic flux on the X/Y/Z axis is larger and larger, the resultant force (namely, the die length) borne by the 3D magnetic sensor is increased after the 3D magnetic sensor is reflected, and a threshold value for pressing down the three-axis resultant force (the die length) is set. When the 3D magnetic sensor detects that the magnitude of the resultant force (the die length) is larger than a set threshold value within a period of time, the 3D magnetic sensor judges that the key is pressed down, and the key function is realized. When the key is rotated, the magnetic sensor can measure the change of the magnetic flux of the X/Y axis, and specifically: when the knob rotates, the rotating shaft 6 connected with the magnet 2 is driven to rotate, and then the rotating shaft 6 drives the magnet 2 to rotate, so that the magnet 2 rotates relative to the 3D magnetic sensor 1. The magnet 2 comprises an N pole and an S pole, the plane where the N pole and the S pole are located is parallel to the 3D magnetic sensor 1, when the magnet 2 rotates, the direction of a magnetic field can be changed accordingly, correspondingly, components of the magnetic field intensity on an X axis and a Y axis can be changed, components of magnetic flux on the X axis and the Y axis can be changed, the 3D magnetic sensor 1 detects the change of the magnetic field intensity on the X/Y axis direction, the change of the direction of the magnetic field can be judged, and therefore an induction signal is sent out.

Similarly, in other embodiments, when the key moves linearly in the XY plane, since the magnet 2 is also close to or away from the 3D magnetic sensor 1, the resultant force (i.e., the mode length) applied to the 3D magnetic sensor 1 is also reduced or increased, a threshold of the three-axis resultant force (the mode length) for linear movement is set, and when the 3D magnetic sensor detects that the resultant force (the mode length) is smaller (or larger) than the set threshold for a period of time, the key is considered to have moved linearly along the XY plane.

The key depression or linear movement brings the magnet 2 close to or away from the 3D magnetic sensor 1, so that the 3D magnetic sensor 1 detects the changed magnetic flux to emit a signal. When the knob 8 is pressed, the return spring 10 between the knob 8 and the light guide 9 is contracted, and at the same time, the magnet 2 is close to the 3D magnetic sensor 1, and when the knob 8 is released, the return spring 10 is reset, and the magnet 2 is far from the 3D magnetic sensor 1, so that the 3D magnetic sensor 1 can detect the changed magnetic flux and send a signal. The light guide 9 provides brightness to the button for easy operation.

When a user presses, rotates or linearly moves the key moving module, the induction module can recognize that the key is pressed, rotated or linearly moves through the change of magnetic flux, the induction module can send a signal to the control module, and after the signal is processed by the control module, the control module sends a corresponding instruction to the main circuit, so that the equipment can perform corresponding actions such as starting and shutting down, gear shifting, stepless dimming of brightness and the like. Different lighting modes are realized, such as the on-off of the lighting equipment is realized by long pressing of the key, the gear shifting is realized by single pressing, and stepless dimming can be realized by rotating and linearly moving the key. The principle that the control module (singlechip) of the embodiment controls the LED module to realize stepless dimming is as follows: the PWM output end of the STM8S003F3 singlechip outputs PWM waves with variable frequency, and when the pulse width (negative voltage) of the PWM wave control triode Q1A conducting is wider, the LED module is higher in brightness, and otherwise, the LED module is lower.

Secondly, the principle that the control module (singlechip) shifts the LED module is that: as shown in FIG. 3, when a single time is used, the PWM terminal of the STM8S003F3 singlechip controls Q1A to be turned on, so that the power voltage is applied to the anode of the light emitting diode. Meanwhile, the STM8S003F3 single chip microcomputer controls two connected LEDs to be bright, four connected LEDs to be bright or fully bright to realize gear shifting with different illumination intensities, when the single chip microcomputer outputs low level to any two, four or all cathodes of the LEDs 1-LEDs 8, the corresponding LEDs are lightened, and the single chip microcomputer outputs high level to the LEDs of the cathodes to be not lightened (because the positive and negative electrodes of the LEDs are high levels).

The above-mentioned embodiments are only one of the preferred embodiments of the present invention, and the ordinary changes and substitutions performed by those skilled in the art within the technical scope of the present invention should be included in the protection scope of the present invention.
