[0032] In addition, it should be noted that the terms "comprising", "including", or any other variant thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not only include those elements, but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus.

It should be understood that the orientation of the terms "above", "below", "inner", "outer", and the like described by the orientation terms represent the orientation in the normal use state.

[0033] In the following detailed description, a stacking system of optical systems, a stacking method and a method of testing environment of optical systems are provided, in which the stacking system can realize the functions of stacking optical systems and providing the testing environment for the optical systems, i.e., the stacking system can realize multiple functions; in the stacking process of optical systems, since the stacking process may exert external force, impact or high temperature on the light source or optical elements in the optical systems, the light source in the optical systems may be damaged in the stacking process if the light source is in the working state, thus the light source in the optical systems is generally not in the working state in the stacking process, so that the power supply structure is not provided in the stacking system, but part of the optical elements need to be precisely positioned with the light source in the stacking process, and the structure characteristics of the optical elements cannot determine whether the optical elements have been assembled in place, and if the light source is configured to be in the working state only when a small part of the optical elements that need to be precisely positioned are assembled, and the light source is configured to be in the non-working state when the optical elements that do not need to be precisely positioned are assembled, the damage risk of the light source in the stacking process can be controlled within an acceptable range, and based on the realization of this, the applicant overcomes the technical bias in the field and creatively proposes to provide a circuit board that can supply power in the stacking system, when the optical elements that need to be precisely positioned are assembled, the function of the light source is realized through the circuit board, the optical elements output light signals through the light source, and whether the optical elements are installed in place is determined according to the state of the light signals output by the light source, at the same time, when other optical elements that do not need to be precisely positioned are assembled, the connection between the circuit board and the light source is disconnected so that the light source is in the non-working state, and since the stacking system has the circuit board that can supply power, the testing environment required for testing the optical systems can also be provided through the reuse of the circuit board, in which the external electromagnetic signals can be isolated and the required magnetic field can be provided for the optical systems, so that the stacking system can not only be used for stacking optical systems but also be used for providing the testing environment for testing the optical systems. In order to make the structure and function of the stacking system clearer, the following embodiments will be further illustrated.

[0034] The stacking system provided in the following embodiments is used for stacking optical systems, which can be any system having a light source and optical elements, in order to facilitate the description, the structure of the optical system will be illustrated in the following embodiments. Figure 1 The structure of the optical system will be illustrated in the following embodiments.

[0035] The optical system 1 comprises a base plate 10, a light source 20, a sensor device 30, a polarization device 40 and a functional device 50. The sensor device 30 is fixed to the base plate 10, and the sensor device 30 is a device sensitive to weak electric signals, and is used to realize the function of a sensor, for example, to acquire external electromagnetic signals and make adaptive correction to the output signal of the light source 20; the light source 20 is connected with the sensor device 30 and can obtain electric energy from the base plate 10 to output a light signal; the polarization device 40 is fixedly connected with the light source 20, and is used to adjust the polarization direction of the light signal output by the light source 20, so that the output light signal oscillates in a specific plane perpendicular to the propagation direction of the light signal; the functional device 50 is fixedly connected with the polarization device 40, and is used to process the light signal that has passed through the polarization device 40 according to the needs of the optical system 1, for example, the functional device 50 can be an attenuation sheet used to attenuate the power of the light signal, and for example, the functional device 50 can be a wave plate used to adjust the phase of the light signal. The relative angle between the polarization device 40 and the light source 20 has a great influence on the polarization direction of the light signal output by the optical system 1, and the relative angle between the polarization device 40 and the light source 20 needs to be accurately positioned. The principles of how the stacking system realizes the stacking of the optical system and how the relative angle between the polarization device 40 and the light source 20 is accurately positioned during the stacking process will be described below in conjunction with the embodiments.

[0036] In some embodiments, as shown in Figure 2 The stacking system 100 comprises a circuit board 110, a clamping device 120 and a rotating device 130. The circuit board 110 has a power supply pin 111 for obtaining electric energy from the outside.

[0037] The clamping device 120 is fixed to the circuit board 110 and is used to fix the base plate 10. It can be understood that during the stacking of the optical system, the base plate 10, the sensor device 30 and the light source 20 are fixed as a whole, and the clamping device 120 is fixedly connected with the base plate 10 through a clamping structure, so as to fix the base plate, the sensor device 30 and the light source 20 with the circuit board 110 through the clamping device 120.

[0038] The rotating device 130 is used to clamp the polarization device 40 and drive the polarization device 40 to rotate relative to the light source 20, so as to adjust the relative angle between the polarization device 40 and the light source 20, and adjust the polarization angle of the light signal output by the polarization device 40.

[0039] In some embodiments, as shown in Figure 3As shown, the circuit board 110 has a first power supply contact 112, which is electrically connected with the power supply pin 111, so that the power obtained by the power supply pin 111 can be transmitted to the first power supply contact 112; the clamping device 120 has a conductive structure 121, which is fixedly connected with the bottom plate 10, and in the state that the clamping device 120 is fixed on the circuit board 110, the conductive structure 121 is connected with the first power supply contact 112, so that the clamping device 120 can not only fix the bottom plate 10, the sensor 30 and the light source 20 on the circuit board 110, but also transmit the power obtained by the power supply pin 111 to the bottom plate 10 through the first power supply contact 112 and the conductive structure 121, so that the bottom plate 10 can transmit the power to the light source 20, that is, the power obtained by the circuit board 110 can be transmitted to the light source 20, so that the light source 20 is in a working state, at this time, the light signal output by the light source 20 can be output after passing through the polarization piece 40, and according to the different relative angles between the polarization piece 40 and the light source 20, the state of the output light signal is different, and according to the state of the output light signal, it can be determined whether the relative angle between the polarization piece 40 and the light source 20 meets the positioning requirement, so as to realize high-precision positioning between the polarization piece 40 and the light source 20. The method for determining whether the polarization piece 40 and the light source 20 are installed in place according to the state of the light signal output by the polarization piece 40 will be exemplarily described below.

[0040] For example, the state of the light signal output by the polarization piece 40 can be obtained by a polarized light test device, which includes a polaroid and a light receiver. The polarization direction of the polaroid is consistent with the target direction, and the light signal output by the polarization piece 40 passes through the polaroid and then enters the light receiver. The intensity of the light signal entering the light receiver can be obtained by the light receiver. The polarization direction of the light signal output by the polarization piece 40 can be changed by rotating the polarization piece 40 by the rotating device 130, so that the intensity of the light signal passing through the polaroid changes. During the process of rotating the polarization piece 40, if the intensity of the light signal obtained by the light receiver reaches a maximum value, it means that the polarization direction of the light signal output by the polarization piece 40 has reached consistency with the target polarization direction, and in this state, it can be determined that the relative angle between the polarization piece 40 and the light source 20 meets the requirement, that is, the precise positioning between the polarization piece 40 and the light source 20 is realized. After the polarization piece 40 and the light source 20 are positioned, they are fixedly connected by a surfactant or glue. It should be noted that the polarized light test device can be part of the stacking system 100, that is, the stacking system 100 has a polarized light test function. The stacking system 100 can also not have the polarized light test device, and the assembly personnel can configure the polarized light test device to obtain the polarization state of the light signal output by the polarization piece 40.

[0041] It should be noted that the adjustment of the relative position of the elements of the system in the powered state can be applied to the optical system, and because the light signal is transmitted between the two elements instead of the electrical signal, compared with adjusting the relative position of the two electrical elements transmitting the electrical signal when assembling the power supply system, there is no risk of damage to the electrical elements due to the sudden change of current or voltage in the circuit.

[0042] The embodiment of the present application provides a stacking system of an optical system, the stacking system is used for stacking the optical system, the optical system comprises a bottom plate, a light source and a polarization piece, and the stacking system comprises: a circuit board with a power supply pin and a first power supply contact, a clamping device used for fixing the bottom plate and fixedly connected with the circuit board, and a rotating device used for clamping the polarization piece and rotating the polarization piece relative to the light source, wherein the power supply pin is used for obtaining electrical energy from the outside and transmitting the electrical energy to the first power supply contact, the clamping device has a conductive structure, and in the state that the clamping device is fixedly connected with the circuit board, the conductive structure connects the first power supply contact and the bottom plate, so that the electrical energy obtained by the circuit board can be transmitted to the light source through the bottom plate, thereby supplying power to the light source and enabling the light source to output a light signal, at this time, the light signal output by the light source can be output after passing through the polarization piece, and according to different relative angles of the polarization piece and the light source, the state of the output light signal is different, and according to the state of the output light signal, whether the relative angle of the polarization piece and the light source meets the positioning requirement can be determined, so that high-precision positioning between the polarization piece and the light source is realized.

[0043] In some embodiments, as shown in Figure 4 The stacking system 100 further comprises a first fixing seat 140 made of insulating material, and the first fixing seat 140 is used for carrying the circuit board 110, wherein the rotating device 130 is connected with the first fixing seat 140, and it can be understood that the first fixing seat 140 provides an assembly position for the rotating device 130, after the circuit board 110 is carried on the first fixing seat 140 and the relative position of the circuit board 110 and the first fixing seat 140 is determined, the relative position of the rotating device 130 and the circuit board 110 can be determined, so that the relative position of the rotating device 130 and the polarization piece 40 can be determined, and then the adjustment of the rotating device 130 to the polarization piece 40 is more accurate, and because the first fixing seat 140 is made of insulating material, the electrical isolation between the rotating device 130 and the circuit board 110 can be realized, so that the electrical energy obtained by the circuit board 110 cannot be transmitted to the polarization piece 40 by the rotating device 130, thereby reducing the risk that the optical performance of the polarization piece 40 is affected due to the slight deformation of the polarization piece 40 caused by power-on.

[0044] In some embodiments, as shown in Figure 5 , the stacking system 100 further comprises a second fixing seat 150 made of insulating material, and the second fixing seat 150 is used for carrying the light source 20, wherein the second fixing seat 150 is connected with the first fixing seat 140, and it can be understood that the second fixing seat 150 provides an assembly position for the light source 20, after the light source 20 is carried on the second fixing seat 150 and the relative position of the light source 20 and the second fixing seat 150 is determined, the relative position of the light source 20 and the circuit board 110 can be determined, so that the relative position of the light source 20 and the polarization piece 40 can be determined, and then the adjustment of the light source 20 to the polarization piece 40 is more accurate, and because the second fixing seat 150 is made of insulating material, the electrical isolation between the light source 20 and the circuit board 110 can be realized, so that the electrical energy obtained by the circuit board 110 cannot be transmitted to the polarization piece 40 by the light source 20, thereby reducing the risk that the optical performance of the polarization piece 40 is affected due to the slight deformation of the polarization piece 40 caused by power-on. Figure 4The first fixing seat 140 in the circuit board 110 includes a fixing bottom wall 141 and a fixing side wall 142. The fixing bottom wall 141 has a first fixing surface 143, for example, the top surface of the fixing bottom wall 141, and the circuit board 110 is fixed to the first fixing surface 143; the fixing side wall 142 extends from the first fixing surface 143 and forms a second fixing surface 144, that is, the end surface of the fixing side wall 142 away from the first fixing surface 143 forms the second fixing surface 144, and the rotating device 130 is fixed to the second fixing surface. In the state that the circuit board 110 is fixed to the fixing bottom wall 141, the dimension D1 of the power supply pin 111 protruding from the first fixing surface 143 is less than the dimension D2 of the second fixing surface 144 protruding from the first fixing surface 143. It can be understood that, in the state that the circuit board 110 is assembled to the first fixing surface 143, the second fixing surface 144 is higher than the top surface of the power supply pin 111, thereby reducing the possibility of motion interference between the rotating device 130 and the power supply pin 111. At the same time, by increasing the distance between the mounting position of the rotating device 130 and the power supply pin 111, the electrical isolation between the power supply pin 111 and the rotating device 130 is more reliable. At the same time, by making the extension direction of the fixing side wall 142 different from the extension direction of the fixing bottom wall 141, the distance between the mounting position of the rotating device 130 and the power supply pin 111 can be increased without increasing the size of the first fixing surface 143.

[0045] In some embodiments, as shown in FIG. 1, Figure 6 Figure 4 ​The rotating device 130 in the first fixing seat 140 includes a supporting rod 131, a fixing structure 132, a rotating structure 133, and a clamping structure 134. The supporting rod 131 is fixed to the first fixing seat 140 and extends away from the first fixing seat 140 to form a distal end. The fixing structure 132 is fixedly connected to the supporting rod 131, and the connection position of the fixing structure 132 and the supporting rod is close to the distal end. It can be understood that by making the supporting rod 131 away from the fixing seat, the connection position of the fixing structure 132 and the supporting rod 131 is located away from the first fixing seat 140, thereby reducing the possibility of assembly interference between the fixing structure 132 and the first fixing seat 140. The rotating structure 133 is rotatably connected to the fixing structure 132, and the clamping structure 134 is fixedly connected to the rotating structure 133 and can clamp the polarizing piece 40. The rotating structure 133 can drive the rotating structure to rotate relative to the fixing structure 132, thereby driving the clamping structure 134 to rotate relative to the fixing structure 132, and further driving the polarizing piece 40 to rotate relative to the fixing structure 132. Since the fixing structure 131 is fixedly connected to the circuit board 110 through the first fixing seat 140, and the light source 20 is fixedly connected to the circuit board 110, the rotating structure 133 can drive the polarizing piece 40 to rotate relative to the light source 20. The specific structure of the rotating structure, the fixing structure, and the clamping structure will be described below to illustrate the principle that the rotating structure can rotate relative to the fixing structure and the clamping structure can clamp the polarizing piece 40.

[0046] The side wall of the fixing structure is a cylindrical curved surface, and a positioning groove is formed in the side wall. The outer surface of the rotating structure protrudes to form a positioning boss, which extends into the positioning groove to limit the vertical direction of the rotating structure and the fixing structure. A gear ring is arranged in the positioning groove, and the positioning boss is provided with a gear that is rotatably connected to the positioning boss. The gear is engaged with the gear ring, and the rotating structure has a servo motor. The servo motor can drive the gear to rotate, and the action force between the gear and the gear ring can drive the gear to revolve around the vertical center axis of the gear ring, thereby driving the rotating structure to rotate relative to the fixing structure. At least two rotating structures are arranged at intervals around the vertical center axis of the gear ring, and at least two clamping structures protrude from the rotating structure. During stacking, the vertical center axis of the gear ring coincides with the vertical center axis of the polarizing piece, and the plurality of clamping structures surround and contact the polarizing piece, thereby achieving clamping of the polarizing piece.

[0047] The clamping structure is connected with the rotating structure so as to drive the clamping structure to rotate. Optionally, the clamping structure is fixedly connected with the rotating structure. Optionally, the rotating structure forms a strip structure similar to an L shape, which includes a vertically extending long arm and a horizontally extending short arm. The long arm is rotatably connected with the fixed structure, and the short arm is used to carry the clamping structure. Meanwhile, the rotating structure also has a pressing piece capable of sliding along the extension direction of the long arm. By moving the pressing piece downward, the clamping structure can be clamped between the short arm and the pressing piece, so that the rotation of the rotating structure can be transmitted to the clamping structure. By moving the pressing piece upward, the clamping of the clamping structure can be released. At this time, the rotation of the rotating structure will not be transmitted to the clamping structure. It can be understood that, during the assembly of the rotating device, the pressing piece releases the clamping of the clamping structure, and the rotating movement generated during the assembly process will not be transmitted to the clamping structure, so that the polarizing piece will not be rotated. In the state that the angle of the polarizing piece needs to be adjusted after the assembly is completed, the pressing piece is pressed to the clamping structure so as to drive the clamping structure to rotate the polarizing piece, thereby further improving the angle adjustment accuracy of the polarizing piece.

[0048] In some embodiments, as shown in Figure 7 The stacking system 100 further includes a second fixing seat 150 for fixedly connecting with the clamping device 120. The clamping device 120 is detachably connected with the second fixing seat, and is detachably connected with the circuit board 110 in the Figure 2 It can be understood that, after the stacking of the polarizing piece 40 and the light source 20 is completed, the clamping device 120 can be detached from the circuit board 110 and assembled in the second fixing seat 150. Therefore, the functional piece 50 and the polarizing piece 40 can be assembled in a state without power supply, that is, in a state that the optical device does not need high-precision positioning, the second fixing seat 150 without power supply is provided to position the bottom plate 10, and the stacking of the optical device without high-precision positioning is completed in a state that the light source 20 is not working, thereby reducing the possibility of damage of the light source 20.

[0049] In some embodiments, as shown in Figure 8As shown, the stacking system 100 further comprises a shielding structure 161 and a coil 162, the shielding structure 161 is connected with the circuit board 110 and surrounds to form an electromagnetic shielding space 163, it can be understood that the shielding structure 161 is made of electromagnetic shielding material through a through hole, and has a cavity inside, which forms the electromagnetic shielding space 163; the coil 162 is fixedly connected with the circuit board 110, and in the state that the coil 162 is fixedly connected with the circuit board 110, the coil 162 is located inside the electromagnetic shielding space 163, and the power supply pin 111 is located outside the electromagnetic shielding space 163, it can be understood that the shielding structure 161 is used to isolate the external magnetic field, which can be understood as the earth magnetic field, the electromagnetic field generated by the power supply pin 111 and the electromagnetic field generated by other electronic devices or cables around the optical system, so that the optical system is only affected by the electromagnetic field generated by the coil 162, and the performance of the optical system in a specific magnetic field can be tested, for example, the polarization angle of the optical signal output by the optical system in different magnetic fields can be tested.

[0050] The circuit board 110 further comprises a second power supply contact 113, the second power supply contact 113 is electrically connected with the power supply pin 111 to obtain power from the power supply pin 111, and in the state that the shielding structure 161 is fixedly connected with the circuit board 110, the second power supply contact 113 is located inside the electromagnetic shielding space 163, and in the state that the coil 162 is fixedly connected with the circuit board 110, the coil 162 is in contact with the second power supply contact 113, that is, the circuit board 110 can supply power to the coil 162 located in the electromagnetic shielding space 163 through the second power supply contact 113, supply power to the light source through the first power supply contact 112, and supply power to the coil through the second power supply contact 113, so that the circuit board 110 can provide power for the test of the optical system; at the same time, the circuit board 110 further has a mounting groove 114, the mounting groove 114 is used for the shielding structure 161 to pass through, for example, the shielding structure 161 comprises a shielding plate and a shielding nose, the shielding plate is located below the circuit board 110, and the shielding nose passes through the mounting groove 114 and is fixedly connected with the shielding plate, so that the shielding structure 161 can completely surround the optical system and the coil 162 on the circuit board 110, and in summary, the circuit board 110 can supply power to the light source during the process of stacking the optical system, and can be multiplexed during the process of testing the optical system, provide a mounting space for the shielding structure 161, and supply power to the light source 20 and the coil 162, so as to provide a test environment for the test of the optical system, that is, the stacking system 100 can realize multiple functions.

[0051] The embodiment of the present application further provides a stacking method of an optical system, which is used for stacking the optical system as shown in any one of the accompanying drawings of the specification Figures 2 to 8 Figure 1 ​The optical system shown is stacked.

[0052] In some embodiments, as Figure 9 shown, Figure 9 A flowchart of a first optical system stacking method provided by an embodiment of the present application is shown, which includes the following steps:

[0053] In step S101, the bottom plate and the light source fixed thereto are fixed by the clamping device, and the clamping device is fixed to the circuit board, and the conductive structure of the clamping device is in contact with the first power supply contact.

[0054] It can be understood that the bottom plate and the light source are fixed to the circuit board by the clamping device, and at the same time, in the assembled state of the clamping device and the circuit board, the electrical energy of the circuit board can be transmitted to the bottom plate by the first power supply contact and the conductive structure, so that the electrical energy is transmitted to the light source by the bottom plate, thereby achieving power supply to the light source.

[0055] In step S102, the rotating device is connected to the polarization piece and the polarization piece is rotated relative to the light source until the light signal output by the polarization piece meets the preset condition.

[0056] It can be understood that the relative angle between the polarization piece and the light source is adjusted by the rotating device, and whether the relative angle between the polarization piece and the light source reaches the target is determined by the state of the light signal output by the polarization piece. For example, the state of the light signal output by the polarization piece can be obtained by a polarized light test device, which includes a polarizer and a light receiver. The polarization direction of the polarizer is consistent with the target direction, and the light signal output by the polarization piece is incident into the light receiver after passing through the polarizer. The intensity of the incident light signal can be obtained by the light receiver. The polarization direction of the light signal output by the polarization piece can be changed by rotating the polarization piece by the rotating device, so that the intensity of the light signal passing through the polarizer changes. During the rotation of the polarization piece, if the intensity of the light signal obtained by the light receiver reaches a maximum value, it means that the polarization direction of the light signal output by the polarization piece has reached consistency with the target polarization direction, and in this state, it can be determined that the relative angle between the polarization piece and the light source meets the requirements.

[0057] In step S103, the polarization piece is fixedly connected to the light source and the rotating device is separated from the polarization piece.

[0058] It can be understood that in the state where the relative angle between the polarization piece and the light source is adjusted to the target angle, the polarization piece and the light source are fixedly connected by the adhesive or the molecular bond between the polarization piece and the light source through the adhesive or the molecular bond.

[0059] In some embodiments, as Figure 10 shown, Figure 10A schematic flowchart of a stacking method for a second optical system provided in an embodiment of the present invention is shown below. Figure 9 The stacking method shown is different, Figure 10 Step S103 includes:

[0060] Step S201: Control the circuit board to stop supplying power to the light source.

[0061] This can be understood as follows: after adjusting the relative angle between the light source and the polarizing element, and before fixing the polarizing element to the light source, power supply to the light source is stopped. Simultaneously, the rotating device maintains its clamping hold on the polarizing element, thus keeping the relative angle between the polarizing element and the light source constant. This reduces damage to the light source during subsequent fixing of the light source and polarizing element, further reducing the possibility of damage to the light source during stacking. Optionally, a switch can be installed between the power supply pin and the external light source to disconnect the electrical connection, thereby stopping the circuit board from supplying power to the light source. Alternatively, the power supply pin can be disconnected from the external power supply, depriving the circuit board of external power and thus stopping the circuit board from supplying power to the light source.

[0062] Step S202: Apply adhesive between the polarizing element and the light source to fix the polarizing element and the light source in place.

[0063] This can be understood as fixing the polarizing element and the light source by gluing. In order to improve the reliability of the fixation between the polarizing element and the light source, epoxy resin is used to fix the polarizing element and the light source. Since the light source is already in a de-energized state at this time, the possibility of the light source being damaged by the heat of the epoxy resin is reduced.

[0064] Step S203: Control the rotation device to separate from the polarizing element.

[0065] This can be understood as follows: after the polarizing element and the light source are fixed, the optional device is separated from the polarizing element, thereby reducing the possibility of interference between the subsequent assembly process and the rotating device.

[0066] In some embodiments, the optical system further includes functional components, the stacking system further includes a second mounting base, and the clamping device is detachably connected to the circuit board, such as... Figure 11 As shown, Figure 11 A schematic flowchart illustrating the stacking method of the third optical system provided in this embodiment of the invention, and... Figure 9 The stacking method shown is different in that, Figure 9 Following step S103, the stacking method further includes:

[0067] Step S301: Remove the clamping device from the circuit board and fix the clamping device to the second fixed base.

[0068] It can be understood that the optical system further comprises a functional component, the assembly positioning precision of the functional component and the polarization component is low, thereby the clamping device is dismounted from the circuit board, and the functional component is assembled in the second fixing base, that is, the functional component is assembled in a non-powered environment.

[0069] Optionally, the clamping device is separated from the circuit board through a low-vibration dismounting mode, for example, the clamping device is connected with the circuit board through glue, the glue is melted through a hair dryer, so that the clamping device is separated from the circuit board, thereby the influence of vibration generated in the process of dismounting the clamping device on the optical system is reduced.

[0070] In step S302, the functional component is fixedly connected with the polarization component.

[0071] It can be understood that the polarization component is positioned on the second fixing base in a non-powered state, and the functional component is fixedly connected with the polarization component.

[0072] The embodiment of the present application further provides a method for building a test environment of an optical system. Figure 1 The test environment is realized through a stacking system as shown in Figure 8 The test is used for testing the performance of the optical system in a specific magnetic field environment, the test environment needs to shield the external magnetic field of the optical system, and needs to provide a specific magnetic field.

[0073] In some embodiments, as shown in Figure 12 Figure 12 A flowchart of a method for building a test environment provided by the embodiment of the present application is shown in the figure, and the building method comprises the following steps.

[0074] In step S401, the clamping device is fixedly connected with the optical system, the clamping device is fixedly connected with the circuit board, and the clamping device is connected with the first power supply contact.

[0075] That is, the optical system is fixedly connected with the circuit board through the clamping device, and the circuit board can supply power to the light source through the first power supply contact.

[0076] In step S402, the coil is fixedly connected with the circuit board, and the coil is in contact with the second power supply contact.

[0077] That is, the coil is fixedly connected with the circuit board, and the coil is supplied with power through the circuit board, and the coil can generate a specific magnetic field environment.

[0078] In step S403, the shielding structure is inserted through the mounting slot, and the coil and the optical system are located in an electromagnetic shielding space formed by the shielding structure.

[0079] ​It can be understood that the electromagnetic shielding structure is passed through the mounting groove arranged on the circuit board, so that the shielding structure can completely surround the optical system and the coil on the circuit board, so that the shielding structure can shield the magnetic field outside the electromagnetic shielding space, so that the optical element is only affected by the electromagnetic field generated by the coil.

[0080] The above examples are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application.
