[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Figure 1 The diagram shows a top view of a biomimetic scale-like ambient light according to an embodiment of the present invention, as shown below. Figure 1 As shown, the biomimetic scale ambient light includes: a biomimetic scale ambient light component 1 and an electronic control unit (ECU); wherein, the biomimetic scale ambient light component 1 includes an ambient light base and a scale structure 11 located on the ambient light base;

[0038] ECU 2 is used to control the mechanical movements of the scale structure 11 to mimic the opening and closing movements of animal scales.

[0039] In the biomimetic scale ambient light provided in this embodiment of the invention, the scale structure 11 can mimic the opening and closing action of animal scales under the control of ECU 2, so that the ambient light can realize the dynamic opening and closing of the scales. Combined with the background light of the ambient light, it can achieve a very beautiful and vivid effect. Compared with static ambient lights, it can bring people a brand-new sensory experience. Moreover, it does not require motors and complex transmission structures, and can be made thin, small, low-cost, and widely applicable, such as in automotive interiors, architecture, advertising, consumer electronics, artistic creation and other fields.

[0040] It should be noted that the ECU 2 of this invention can control the working state of the ambient light when controlling the mechanical movements of the scale structure 11. The scale structure 11 has a variety of mechanical movements, and can freely open and close under the control of the ECU 2. It can not only simulate the opening and closing of scales, but also simulate the flapping of insect wings. In addition, the size of the scale structure 11 is flexible and can be determined according to the actual situation, which will not be elaborated here.

[0041] Furthermore, in specific implementations, in the above-mentioned biomimetic scale ambient light provided in the embodiments of the present invention, such as... Figure 2As shown, the scale structure 11 may include a thin film layer 111 with flexible scales (which can be understood as a biomimetic scale base film) and a printed circuit 112 located on the back of the thin film layer 111 and electrically connected to the ECU 2; the flexible scales are formed by cutting the thin film layer 111; the printed circuit 112 is disposed in the area of ​​the scale structure 11 where mechanical action is achieved.

[0042] In implementation, the thin film layer 111 of the scale structure 11 is thin, and the scale structure 11 is manufactured using printed circuit board technology, making it not only lightweight and thin but also low-cost. Specifically, the carrier of the scale structure 11 is a thin film material, obtained by cutting flexible scale shapes into the thin film material, with printed circuits 112 on the back of the flexible scales. Each flexible scale has a corresponding printed circuit 112. The mechanical movement of the scale structure 11 is essentially due to the action of the printed circuits 112, causing the flexible scales to be in an open or closed state.

[0043] It should be pointed out that, Figure 3 The flexible scales shown are triangular in shape, but the shape of the flexible scales includes, but is not limited to, triangles. They can be freely designed, such as regular shapes like ovals, squares, and rhombuses, or they can be irregular shapes. There are no restrictions here, and the shape can be determined according to the actual situation.

[0044] Furthermore, in a specific implementation, in the above-mentioned biomimetic scale ambient light provided in the embodiments of the present invention, ECU 2 is used to control the magnitude, direction and frequency of the current in the printed circuit so as to control the mechanical movement of the flexible scales.

[0045] In practice, ECU 2 can control the magnitude, direction, and frequency of the current in each printed circuit (which can be understood as a wire route) to control the opening and closing of each flexible scale.

[0046] Furthermore, in a specific implementation, in the above-mentioned biomimetic scale ambient light provided in the embodiments of the present invention, the flexible scales are arranged in an array; each column of flexible scales corresponds to a different printed circuit.

[0047] In implementation, with Figure 3For example, there are three rows of flexible flakes in the thin film layer 111. Each row of flexible flakes corresponds to a different printed circuit 112. The current of the printed circuit corresponding to the first row of flexible flakes is I1, the current of the printed circuit corresponding to the second row of flexible flakes is I2, and the current of the printed circuit corresponding to the third row of flexible flakes is I3. That is to say, the mechanical movements of these three rows of flexible flakes do not affect each other. The ECU 2 controls the magnitude, direction, and frequency of the current I1 in the printed circuit to control the mechanical movement of the first row of flexible flakes; the ECU 2 controls the magnitude, direction, and frequency of the current I2 in the printed circuit to control the mechanical movement of the second row of flexible flakes; and the ECU 2 controls the magnitude, direction, and frequency of the current I3 in the printed circuit to control the mechanical movement of the third row of flexible flakes.

[0048] Of course, each flexible scale can also correspond to a printed circuit, in order to Figure 1 For example, there are three rows of flexible flakes in the thin film layer, and the current of the corresponding printed circuit is I. Therefore, ECU 2 controls the magnitude, direction, and frequency of the current I in the printed circuit, which can control the mechanical movement of all the flexible flakes.

[0049] Furthermore, in a specific implementation, in the above-mentioned biomimetic scale ambient light provided in the embodiments of the present invention, the thin film layer 111 with flexible scales can be one of polyimide (PI), polyester resin (PET), polycarbonate (PC), or copper clad laminate (CCL).

[0050] Of course, the material of the thin film layer 111 includes, but is not limited to, PI, PET, PC, CCL, and may also be other materials.

[0051] When the thin film layer 111 is PI, PET or PC, the printed circuit 112 can be silver wire, copper wire or aluminum wire.

[0052] When the thin film layer 111 is CCL, PI can be used as the base film surface. The printed circuit 112 is formed by etching the copper foil surface in CCL, that is, directly etching the conductive lines on the copper foil surface.

[0053] Furthermore, in specific implementations, in the above-mentioned biomimetic scale ambient light provided in the embodiments of the present invention, such as... Figure 2 As shown, the scale structure 11 also includes an insulating layer 113 located on the back of the thin film layer 111 and covering the printed circuit 112. The insulating layer 113 can protect the thin film layer 111 and the printed circuit 112 in the scale structure 11.

[0054] In practice, the thickness of the entire scale structure 11 can be set between 25 μm and 125 μm, that is, the total thickness of the thin film layer 111 and the insulating layer 113 can be set between 25 μm and 125 μm.

[0055] Furthermore, in specific implementations, in the above-mentioned biomimetic scale ambient light provided in the embodiments of the present invention, such as... Figure 4 and Figure 5 As shown, the biomimetic scale ambient light component 1 may also include a permanent magnet 13 located on the ambient light base 12, and a backlight 14 located between the permanent magnet 13 and the scale structure 11; the areas of the scale structure 11 other than the area that realizes the mechanical action are fixed to the backlight by the colloid 15.

[0056] In implementation, the ambient light base 12 can be made of plastic or metal. The backlight 14 can be, but is not limited to, light-emitting diode (LED) backlight, Micro LED backlight, Mini LED backlight, Organic Light-Emitting Diode (OLED) backlight, electroluminescent (EL) backlight, etc. The backlight 14 can be controlled by its own independent ECU, or it can share an ECU with the scale structure 11. The backlight 14 is also in operation when the scale structure 11 is working; the backlight 14 can be turned on or off when the scale structure 11 is not working. The areas of the scale structure 11 other than the area where mechanical action is achieved (which can be understood as the scale area) are fixed to the backlight 14 by adhesive 15.

[0057] Figure 4 The scale structure 11 in the middle is in a closed state when no electricity is applied. Figure 5 The scale structure 11 in the middle is in the open state when energized, that is, when the ECU 2 energizes the printed circuit, the flexible scales on the thin film layer are in the open state.

[0058] It should be added that, such as Figure 4 and Figure 5 As shown, the biomimetic scale ambient light component 1 may also include a transparent cover plate 16 located on the ambient light base 12 and covering the scale structure 11, the permanent magnet 13, and the backlight 14. The transparent cover plate 16 can be used to protect the scale structure 11 from damage by the external environment.

[0059] Furthermore, in a specific implementation, in the above-mentioned biomimetic scale ambient light provided in the embodiment of the present invention, the area in the scale structure 11 that realizes mechanical action overlaps with the projection of the permanent magnet 13 on the ambient light base 12.

[0060] Furthermore, in specific implementations, in the above-mentioned biomimetic scale ambient light provided in the embodiments of the present invention, such as... Figure 4 and Figure 5 As shown, the ambient light base 12 includes multiple grooves; the permanent magnet 13 is fixed in the grooves of the ambient light base 12.

[0061] In practice, the permanent magnet 13 can be fixed in the groove of the ambient light base 12 using structural adhesive. The magnetic poles of the permanent magnet 13 can be vertical or at a certain angle.

[0062] Figure 6 This is a schematic diagram illustrating the working principle of the biomimetic scale-like ambient light provided in an embodiment of the present invention. Figure 6 As shown, the position of the electrodes of the permanent magnet 13 is determined by Ampere's law, depending on the orientation of the printed circuit 112 on the scale structure and the direction of the current. The optimal position and tilt angle of the permanent magnet 13 can be determined by simulation software. Assuming that the current direction of the printed circuit 112 is from the outside to the inside, the N pole of the permanent magnet is close to the printed circuit 112, and the S pole is far away from the printed circuit 112. The current-carrying wire of the printed circuit 112 experiences an Ampere force in the magnetic field. Because the flexible scale is made of a soft thin film material, when there is no current flowing through the printed circuit 112, the flexible scale is in a naturally closed state. When a current in a specific direction is applied to the printed circuit 112 on the flexible scale, the current-carrying wire of the printed circuit 112 will experience an upward component force F, which will drive the edge of the flexible scale to move upward, and the flexible scale will complete the opening action. When the current is removed, the Ampere force disappears, and the flexible scale returns to the closed state.

[0063] The following is a specific example to illustrate the above-mentioned biomimetic scale-like ambient light provided in the embodiments of the present invention:

[0064] First, CCL (Ceramic Cl-) was selected as the thin film layer with flexible flakes. The PI thickness in the CCL was 12.5 μm, and the copper foil thickness was 18 μm. The processing flow is as follows:

[0065] The first step is to etch the copper foil with a line width of 1.5mm. After etching, an insulating protective layer with a thickness of 7μm is printed on the surface of the copper foil.

[0066] Step 2, as follows Figure 7 As shown, flexible scales are cut into the CCL film to obtain flexible structure 11, wherein the side length of the flexible scales is 10mm and the included angle of the flexible scales is 60°.

[0067] Then, select neodymium iron boron permanent magnets, such as... Figure 8 As shown, the permanent magnet has a diameter of 4mm and a height of 3mm. Figure 9 As shown, the N pole of the permanent magnet is designed with a cut close to the flexible scale.

[0068] like Figure 10 As shown, after the bionic scale ambient light is assembled, the scale structure 11 is powered on, and the flexible scales of the scale structure 11 change from closed to open. The opening height of the flexible scales is h.

[0069] It should be noted that the power supply signal from the ECU to the scale structure 11 is adjustable, as shown in Table 1 below, which illustrates the relationship between the current magnitude and the scale opening height:

[0070] Table 1

[0071] Current (direct current) 0.5A 1A 1.5A 2A Opening amplitude h 1.2mm 2.3mm 2.9mm 3.5mm

[0072] like Figure 11 As shown, the ECU can also provide square wave DC or sinusoidal DC signals to the scale structure 11. For example... Figure 12 As shown, the flexible scales of the scale structure 11 can realize the action of cyclic flapping, and the flapping frequency f (Hz) depends on the frequency of the DC square wave signal.

[0073] It should be emphasized that the size and shape of the flexible scales of the thin film layer 111 in the scale structure 11 designed in this invention, the conductive line width, current magnitude, direction and waveform of the printed circuit 112, and the specifications and magnet direction of the permanent magnet 13 are all flexible and can be adjusted according to the working principle provided by this invention.

Furthermore, it eliminates the need for motors and complex transmission structures, allowing for lightweight, miniaturized, low-cost, and wide-ranging applications, such as in automotive interiors, architecture, advertising, consumer electronics, and artistic creation.
