[0094] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0095] The technical solutions disclosed in various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0096] This application provides a multi-head chandelier in a specific embodiment, such as Figure 14A and Figure 18A As shown, the multi-head chandelier includes a chandelier body 800 and a plurality of lighting modules. The lighting module is provided with a cantilever 700, and the lighting module is connected to the chandelier body 800 through the cantilever 700. At the same time, the lighting module can make the multi-head chandelier present different styles by installing different styles of lampshades 100, such as Figure 14A In the lighting module, the multi-head chandelier is made to look like a columnar chandelier by installing a columnar lampshade 110. Figure 18A In the figure, the lighting module makes the multi-head chandelier appear in the style of a spherical chandelier by installing a spherical lampshade 110. Of course, the lampshade 100 is not limited to the above examples. The lighting module can also make the multi-head chandelier appear in other styles by installing other forms of lampshades 100, which is not limited here.

[0097] The following introduces the lighting module involved in the multi-head chandelier. As mentioned above, the lighting module can present different styles by installing different lampshades 100.

[0098] First, a general introduction is given to the lighting module in which the cylindrical lampshade 110 is installed.

[0099] Please refer to Figure 8 、 Figure 14 and Figure 15 The lighting module forms a cylindrical wall lamp by installing a cylindrical lampshade 110. The lighting module includes a cylindrical lampshade 110, a cantilever 700, a mounting base 600, a light source module G, and a fixing assembly S. The bottom of the cylindrical lampshade 110 is provided with a cover opening 100A, and the interior is hollow to form a lighting area.

[0100] When assembling the lighting module, first install the fixing component S at the cover opening 100A, then place the light source module G in the lighting area inside the cylindrical lampshade 110, and connect the light source module G to the fixing component S, and then fix the head end of the mounting base 600 on the fixing component S from the outside of the cylindrical lampshade 110, and finally install the cantilever 700 on the tail end of the mounting base 600 to complete the installation of the entire lighting module.

[0101] It should be noted that the fixing assembly S serves as the connecting hub of the lighting module, connecting the cylindrical lampshade 110, the light source module G, and the mounting base 600 together through the fixing assembly S. As an optional layout, the light source module G and the mounting base 600 can be fixed to two opposite end surfaces of the fixing assembly S, with the outer periphery of the fixing assembly S passing through and fixed to the cover opening 100A.

[0102] It should also be noted that the fixing component S is a universal part, and its purpose is to connect the lampshade 100 to other parts in the lighting assembly through the fixing component S. That is to say, the fixing component S can not only be installed in the cylindrical lampshade 110 mentioned above, but also can be installed in other forms of lampshades 100 such as spherical lampshades 120.

[0103] The following first introduces the installation of the fixing assembly S in the cylindrical lampshade 110 .

[0104] like Figure 4 、 Figure 8 and Figure 15 As shown, the fixing assembly S may include an inner connecting ring 200 and an outer connecting ring 400. The inner connecting ring 200 is disposed inside the cylindrical lampshade 110, and the outer connecting ring 400 is disposed outside the cylindrical lampshade 110, with the cover opening 100A located between the inner connecting ring 200 and the outer connecting ring 400.

[0105] like Figure 3 、 Figure 6 and Figure 16 As shown, the area surrounding the lampshade opening 100A is provided with an inner mounting surface 100C within the cylindrical lampshade 110 and an outer mounting surface 100B outside the cylindrical lampshade 110. The inner connecting ring 200 is provided with an inner clamping surface 200E on its end surface, which mates with the inner mounting surface 100C. The outer connecting ring 400 is provided with an outer clamping surface 400A on its end surface, which mates with the outer mounting surface 100B.

[0106] like Figure 9 and Figure 16 As shown, the internal connecting ring 200 and the external connecting ring 400 are connected to each other, so that the inner clamping surface 200E presses the inner mounting surface 100C, and the outer clamping surface 400A presses the outer mounting surface 100B, so that the fixing component S is fixed to the cylindrical lampshade 110 by clamping, so that the cylindrical lampshade 110 is connected to the light source module G, the mounting seat 600 and other parts through the fixing component S.

[0107] It should be pointed out here that the above description is only a specific feasible solution. As for the connection method between the fixing component S and the cylindrical lampshade 110, the internal connecting ring 200 and the external connecting ring 400 can also be connected to the cylindrical lampshade 110 respectively, thereby achieving the mutual fixation of the fixing component S and the cylindrical lampshade 110. This will not be described in detail here.

[0108] In an optional embodiment, an end face fixing method can be adopted to fix the light source module G on the built-in connecting ring 200, and the mounting base 600 on the external connecting ring 400, such as fixing the end face of the light source module G on the end face of the built-in connecting ring 200, or fixing the mounting base 600 on the end face of the external connecting ring 400 by bonding or welding.

[0109] A specific implementation scheme adopted in this application is as follows Figure 15 As shown, the fixing component S can be provided with a connection module 510. The connection module 510 is passed through the through hole formed by the built-in connection ring 200 and the external connection ring 400. The connection module 510 is connected to the built-in connection ring 200 or the external connection ring 400 alone, or is connected to both the built-in connection ring 200 and the external connection ring 400, so as to achieve a sealing setting at the cover opening 100A and to achieve a fixing through the fixing component S. For example, the connection module 510 is tightened and fixed by means of interference fit with the built-in connection ring 200 and / or the external connection ring 400. The two opposite ends of the connection module 510 are respectively connected to the light source module G and the mounting base 600. For example, the light source module G and the mounting base 600 are fixed to the connection module 510 by means of bolt connection, bonding, riveting, snap-on connection with a snap-on slot, etc.

[0110] More specifically, the outer circumference of the connection module 510 is provided with external threads, and the inner circumference of the inner connection ring 200 and / or the inner circumference of the outer connection ring 400 is provided with internal threads. The connection module 510 is threadedly connected to the inner connection ring 200 and / or the outer connection ring 400 and is fixed in the fixing assembly S.

[0111] Furthermore, the connection module 510 can be configured as a heat dissipation module to dissipate the heat accumulated in the cylindrical lampshade 110 when the light source module G is working to the outside of the cylindrical lampshade 110 to prevent the internal temperature of the cylindrical lampshade 110 from being too high.

[0112] In some embodiments, as Figure 6 As shown, the external connecting ring 400 may include a third boss 400B. The external clamping surface 400A is located on the same side as the third boss 400B and surrounds the outside of the third boss 400B. By interconnecting the internal connecting ring 200 and the external connecting ring 400, the third boss 400B can be inserted into the cover opening 100A. This allows the cover opening 100A to limit the third boss 400B, thereby radially securing the fixing assembly S and preventing movement of the fixing assembly S along the radial direction of the cover opening 100A.

[0113] Furthermore, a corresponding boss can also be provided on the inner connecting ring 200, and this boss can be located on the same side as the inner clamping surface 200E. The inner clamping surface 200E encloses this boss. In this way, when the inner connecting ring 200 and the outer connecting ring 400 are connected, the third boss 400B can cooperate with the boss provided on the inner connecting ring 200, thereby more effectively achieving radial fixation of the fixing assembly S at the cover opening 100A.

[0114] As an optional connection solution for the internal connection ring 200 and the external connection ring 400, Figure 1 and Figure 5 As shown, a first connecting portion 210 is provided on the inner connecting ring 200, and a second connecting portion 410 is provided on the outer connecting ring 400. For example, the first connecting portion 210 is a buckle provided on the inner connecting ring 200, and the second connecting portion 410 is a buckle provided on the outer connecting ring 400, thereby connecting the inner connecting ring 200 to the outer connecting ring 400. For another example, the first connecting portion 210 and the second connecting portion 410 are strong adhesive layers that complement each other, and the inner connecting ring 200 is connected to the outer connecting ring 400 through mutual adhesion.

[0115] As the specific connection scheme adopted by the internal connection ring 200 and the external connection ring 400 in this application, Figure 9 、 Figure 10 and Figure 15 As shown, the fixing assembly S may further include a fastener 500. The first connecting portion 210 and the second connecting portion 410 are both through holes. The fastener 500 sequentially penetrates the first connecting portion 210 and the second connecting portion 410 to achieve connection between the internal connecting ring 200 and the external connecting ring 400.

[0116] Here, the fastener 500 can be a combination of a bolt and a nut. The first connecting portion 210 and the second connecting portion 410 are both through-holes. By sequentially inserting bolts into the first connecting portion 210 and the second connecting portion 410, and then threading the nuts into the bolts, the connection between the internal connecting ring 200 and the external connecting ring 400 is achieved. The fastener 500 can also be as follows. Figure 9 The figure shows a bolt, and the first connecting part 210 and the second connecting part 410 are respectively a threaded through hole and a threaded hole. The bolt passes through the threaded through hole and connects the threaded holes to realize the connection between the internal connecting ring 200 and the external connecting ring 400. Of course, the fastener 500 can also be a rivet, and the connection between the internal connecting ring 200 and the external connecting ring 400 can be realized by riveting with rivets.

[0117] As an optional layout of the first connecting portion 210 and the second connecting portion 410, as Figure 1 and Figure 5 As shown, the first connecting portion 210 is provided on the inner circumference of the internal connecting ring 200, and the inner clamping surface 200E is provided on the outer circumference of the internal connecting ring 200, surrounding the outer side of the first connecting portion 210. The second connecting portion 410 is provided on the inner circumference of the external connecting ring 400, and the outer clamping surface 400A is provided on the outer circumference of the external connecting ring 400, surrounding the outer side of the second connecting portion 410. In this way, the inner circumference of the fixing assembly S is used for connection, while the outer circumference is used to clamp the cylindrical lampshade 110, achieving functional zoning and non-interference.

[0118] Furthermore, you can Figure 2 and Figure 6 As shown, the first connecting portion 210 is disposed on the boss of the internal connecting ring 200, while the external connecting ring 400 is disposed on the third boss 400B, so as to make the structure of the fixing assembly S more compact.

[0119] In some embodiments, as Figure 1 and Figure 5 As shown, the external connecting ring 400 is provided with a second heat dissipation hole 420; the internal connecting ring 200 is provided with a first heat dissipation hole 220, which is arranged around the rotation axis O of the internal connecting ring 200. The second heat dissipation hole 420 and the first heat dissipation hole 220 correspond in position and are oriented in the same direction. This allows heat generated within the cylindrical lampshade 110 to be dissipated to the outside world through the first heat dissipation hole 220 and the second heat dissipation hole 420, respectively, thereby reducing the temperature within the cylindrical lampshade 110.

[0120] Further, such as Figure 1 and Figure 2As shown, because the diameter of the conventional cover opening 100A is smaller than that of the internal connecting ring 200, in order to conveniently place the internal connecting ring 200 within the cylindrical lampshade 110, the internal connecting ring 200 is configured as an open ring having a first notch 230 formed around the rotation axis O. If the internal connecting ring 200 is made of a relatively soft material, external force can be applied to elastically deform the internal connecting ring 200, thereby reducing the size of the first notch 230 and the diameter of the internal connecting ring 200. This allows the internal connecting ring 200 to be installed within the cylindrical lampshade 110 through the cover opening 100A, making installation more convenient. If the internal connecting ring 200 is made of a relatively hard material, it can also be inserted into the cylindrical lampshade 110 through the first notch 230 and then flipped within the cylindrical lampshade 110 to be installed on the inner mounting surface 100C.

[0121] Of course, for some cylindrical lampshades 110 with an opening at the top, the built-in connecting ring 200 can be placed from the top of the cylindrical lampshade 110. In this case, the built-in connecting ring 200 does not need to be opened and can be set as a full ring structure.

[0122] More preferably, the built-in connecting ring 200 is made of plastic material. This way, firstly, it can better apply external force to change the size of its diameter so that it can be placed in the cylindrical lampshade 110. Secondly, when the built-in connecting ring 200 and the external connecting ring 400 are connected and the cylindrical lampshade 110 is clamped, since the plastic material is softer, it can be avoided that when the clamping force is too large, the built-in connecting ring 200 causes damage to the cylindrical lampshade 110 on the inside. Similarly, the external connecting ring 400 can also be made of plastic material.

[0123] As another optional solution, in order to make the external connection ring 400 protect the cylindrical lampshade 110, the external connection ring 400 is made of a metal material that is not easy to deform. Figure 4 and Figure 9 The flexible pad 300 shown is usually made of materials such as silicone and is applied to the outer clamping surface 400A. In this way, through the buffering of the flexible pad 300, it is possible to effectively avoid damage to the cylindrical lampshade 110 caused by the external connecting ring 400 on the outside when the clamping force is too large.

[0124] The light source module G adapted for the cylindrical lampshade 110 is introduced below.

[0125] like Figure 20 and Figure 24 As shown, the light source module G is located in the lighting area of ​​the cylindrical lampshade 110 , and is used to emit light to illuminate the cylindrical lampshade 110 and illuminate the light to the outside through the cylindrical lampshade 110 .

[0126] like Figure 26The light source module G shown includes a light source module 3, which is provided with a light source 31. The light source module G emits light through the light source 31. The light source 31 can be a LED dot matrix light, and to adapt to the characteristics of the rotating structure of the cylindrical lampshade 110, the light source 31 can be arranged in a ring array.

[0127] like Figures 27 to 29 As shown, the light source module 3 is provided with a light distribution element, which is adapted to the lampshade 100 and can evenly distribute the light emitted by the light source 31 to the lighting area of ​​the lampshade 100. For example, if the lampshade 100 is a cylindrical lampshade 110, the light distribution element is selected to be a light guide mirror 5 adapted to the cylindrical lampshade 110.

[0128] Furthermore, the light source module G also includes a lens fixture 2 and a light source fixture 4. The lens fixture 2 is used to connect the light guide 5 to the fixing assembly S (specifically, the connecting module 510), while the light source module 3 is located between the light guide 5 and the fixing assembly S. The light source fixture 4 is used to connect the light source module 3 to the fixing assembly S. In this way, the light source module G can be fixed to the connecting module 510.

[0129] In a further embodiment, Figure 21 and Figure 26 As shown, the light guide mirror 5 is provided with a light guide mirror connecting portion 51, which is a flange structure formed on the outer periphery of the light guide mirror 5 and is provided with a threaded through hole. The light source module 3 is also provided with a threaded through hole.

[0130] like Figures 27 to 29 As shown, the lens fixing member 2 and the light source fixing member 4 can both be configured as bolts. Corresponding threaded holes are provided on the connection module 510. The lens fixing member 2 passes through the light guide mirror connection portion 51 and connects to the threaded holes on the connection module 510, thereby securing the light guide mirror 5 to the connection module 510. The light source fixing member 4 passes through the light source module 3 and connects to the threaded holes on the connection module 510, thereby securing the light source module 3 to the connection module 510.

[0131] It should also be noted that the light source module G is also a universal component and can be adapted to the corresponding lampshade 100 by selecting different light distribution components. For example, the light source module G described above is adapted to the cylindrical lampshade 110 by selecting the light guide 5, and the light source module G can also be adapted to the spherical lampshade 120 by selecting the beam splitter 6. The light source module G with the beam splitter 6 as the light distribution component will be described in detail later.

[0132] The light guide mirror 5 serving as the light distribution element in the light source module G will be described below.

[0133] like Figure 24A and Figure 24As shown, the light guide mirror 5 is disposed at the bottom of the cylindrical lampshade 110 and is located in the lighting area of ​​the cylindrical lampshade 110 .

[0134] The lighting area of ​​the cylindrical lampshade 110 includes a low-beam area 110B close to the light guide 5 and a high-beam area 110A away from the light guide 5. As can be seen from the structural characteristics of the cylindrical lampshade 110, the distance between any position on the lighting area of ​​the cylindrical lampshade 110 and the light guide 5 gradually increases from the low-beam area 110B to the high-beam area 110A. Therefore, if the light source 31 is used directly for incident light, the low-beam area 110B will be brighter, while the high-beam area 110A will be darker. Therefore, the light guide 5 is provided to evenly distribute the incident light from the light source 31 to the lighting area of ​​the cylindrical lampshade 110.

[0135] like Figure 21 and Figure 24 As shown, the light guide mirror 5 is an annular lens that rotates about a first reference axis O1 and has a tapered hole extending along the first reference axis O1. The diameter of the tapered hole gradually increases toward the bottom of the light guide mirror 5. The cylindrical lampshade 110 has a second reference axis O2 as its rotation axis. The first and second reference axes O1 and O2 are coaxially arranged to ensure that the light guide mirror 5 does not deviate relative to the cylindrical lampshade 110, preserving brightness uniformity across the illuminated area.

[0136] like Figure 21 As shown, the inner circumference of the light guide mirror 5 forms a light guide mirror reflective surface 5A, the top surface of the light guide mirror 5 forms a first light guide mirror light exit surface 5B, and the outer circumference of the light guide mirror 5 forms a second light guide mirror light exit surface 5C. The light guide mirror reflective surface 5A, the first light guide mirror light exit surface 5B, the second light guide mirror light exit surface 5C, and the bottom surface of the light guide mirror 5 are connected end to end to form a toroidal surface. The light guide mirror reflective surface 5A is the hole surface of the tapered hole. The bottom surface of the light guide mirror 5 is concavely provided with a light guide mirror light entrance surface 5D. The light source 31 is disposed within the light guide mirror light entrance surface 5D.

[0137] like Figure 24A 、 Figure 24 and Figure 25 It can be seen that after the incident light emitted by the light source 31 enters the light guide mirror 5 through the light guide mirror light entrance surface 5D, it will respectively enter the first light guide mirror light exit surface 5B to form the second light guide mirror light beam Y1, enter the second light guide mirror light exit surface 5C to form the first light guide mirror light beam X1, and be reflected by the light guide mirror reflective surface 5A to enter the first light guide mirror light exit surface 5B to form the third light guide mirror light beam Z1.

[0138] like Figure 24A and Figure 25As shown, a second cross-section B is drawn through the second reference axis O2, and a first extension line Z1′ of the incident light beam entering the reflective surface 5A of the light guide mirror is drawn. As seen from the second cross-section B, the first extension line Z1′ passes through the second reference axis O2 and enters the low beam area 110B. The third light guide mirror light beam Z1 faces away from the second reference axis O2 and enters the high beam area 110A.

[0139] It can be seen that by setting the inclination angle and controlling the profile of the reflective surface 5A of the light guide mirror, part of the incident light originally entering the low beam area 110B (i.e., the first extension line Z1') can be reflected to the high beam area 110A (i.e., the third light guide mirror light beam Z1), thereby achieving a reduction in the brightness of the low beam area 110B and an increase in the brightness of the high beam area 110A, thereby solving the problem of illumination uniformity of the cylindrical lampshade 110 by the light source 31.

[0140] In summary, through the setting of the light guide mirror 5, the light refracted by the light emitting surface 5B of the first light guide mirror will enter the part of the lighting area away from the light guide mirror 5, that is, the second light guide mirror light beam Y1 and the third light guide mirror light beam Z1 will enter the high beam area 110A; and the light refracted by the light emitting surface 5C of the second light guide mirror will enter the part of the lighting area close to the light guide mirror 5, that is, the first light guide mirror light beam X1 will enter the low beam area 110B, thereby realizing the redistribution of the incident light, and then making the lighting area of ​​the cylindrical lampshade 110 uniform.

[0141] Further, such as Figure 21 and Figure 25 As shown, the light guide mirror reflective surface 5A is a curved surface that is recessed toward the bottom of the light guide mirror 5. This concave surface allows the light guide mirror reflective surface 5A to simultaneously reflect and converge incident light. Furthermore, the tilted design of the light guide mirror reflective surface 5A allows the light reflected by the light guide mirror reflective surface 5A to be directed to the first light guide mirror light exit surface 5B with a higher degree of convergence. This allows the formed third light guide mirror light beam Z1 to be more accurately guided to the high beam area 110A, thereby enhancing the brightness enhancement effect of the high beam area 110A.

[0142] Furthermore, Figure 21As shown, the light-emitting surface 5B of the first light guide mirror is a convex curved surface, and is tilted relative to the first reference axis O1. The convex direction of the light-emitting surface 5B of the first light guide mirror is from the bottom of the light guide mirror 5 to the top. The light-emitting surface 5B of the first light guide mirror is tilted, and the light-emitting surface 5B of the first light guide mirror gradually approaches the bottom surface of the light guide mirror 5 as the distance from the first reference axis O1 increases. In this way, by comprehensively controlling the curvature radius and the tilt angle of the light-emitting surface 5B of the first light guide mirror, the second light guide mirror light beam Y1 and the third light guide mirror light beam Z1 can be more accurately guided to the far light area 110A, so that the brightness of the far light area 110A is enhanced. In order to save manufacturing costs, the light-emitting surface 5C of the second light guide mirror can be set to a cylindrical surface or a conical surface, as long as the incident light can finally be projected to the low light area 110B.

[0143] Furthermore, Figure 22 and Figure 23 As shown, a light scattering structure P is provided on the light emitting surface 5B of the first light guide mirror and the light emitting surface 5C of the second light guide mirror. The light scattering structure P can be a surface formed by frosting treatment, so that the light will be diffused when it is irradiated by the light scattering structure P, which can enhance the uniformity of the distribution of light in the lighting area of ​​the cylindrical lampshade 110.

[0144] It should be pointed out here that the provision of the astigmatism structure P on the light emitting surface 5B of the first light guide mirror can also prevent the light from being excessively converged by the light reflecting surface 5A of the light guide mirror to form a light spot located in the far beam area 110A.

[0145] Furthermore, Figure 22 and Figure 23 As shown, the first light guide mirror light exit surface 5B includes a first light guide mirror light scattering area 5B1 and a first light guide mirror light exit area 5B2. The second light guide mirror light exit surface 5C, the first light guide mirror light scattering area 5B1, the first light guide mirror light exit area 5B2, and the light guide mirror reflective surface 5A are sequentially connected. The light scattering structure P is provided on the second light guide mirror light exit surface 5C and the first light guide mirror light scattering area 5B1.

[0146] The design of dividing the light-emitting surface 5B of the first light guide mirror into functional areas can produce different optical effects when the light is refracted. Specifically, by setting the first light guide mirror astigmatism area 5B1, it can prevent the light from converging to form a light spot, and by setting the first light guide mirror light-emitting area 5B2, it can prevent the light from being too dark due to excessive diffusion after being transmitted to the high beam area 110A.

[0147] In some embodiments, as Figure 25 and Figure 25A As shown, the top surface of the light guide mirror light incident surface 5D forms the second light guide mirror light incident surface 5D2, the inner peripheral surface of the light guide mirror light incident surface 5D forms the first light guide mirror light incident surface 5D1, and the outer peripheral surface of the light guide mirror light incident surface 5D forms the third light guide mirror light incident surface 5D3.

[0148] The first light guide mirror's light-entering surface 5D1 is positioned adjacent to the first reference axis O1. The third light guide mirror's light-entering surface 5D3 surrounds the first light guide mirror's light-entering surface 5D1. The second light guide mirror's light-entering surface 5D2 connects the first and third light guide mirror's light-entering surfaces 5D1 and 5D3, respectively. The second light guide mirror's light-entering surface 5D2 is tilted, and its distance from the first reference axis O1 gradually increases from the top to the bottom of the light guide mirror 5.

[0149] After the incident light enters the light guide mirror 5, it will be refracted by the third light guide mirror light incident surface 5D3 to form a first light beam branch L, refracted by the second light guide mirror light incident surface 5D2 to form a second light beam branch M, and refracted by the first light guide mirror light incident surface 5D1 and reflected by the light guide mirror reflective surface 5A to form a third light beam branch N.

[0150] The first light beam branch L is refracted by the second light guide mirror's light exit surface 5C to form the first light guide mirror beam X1. The second light beam branch M is located inside the first light beam branch L and closer to the first reference axis O1 relative to the first light beam branch L. The second light beam branch M is refracted by the second light guide mirror's light entrance surface 5D2 to form the second light guide mirror beam Y1. The third light beam branch N is refracted by the first light guide mirror's light exit surface 5B to form the third light guide mirror beam Z1.

[0151] In this way, by changing the ratio of the first light guide mirror light incident surface 5D1, the second light guide mirror light incident surface 5D2 and the third light guide mirror light incident surface 5D3 in the light guide mirror light incident surface 5D, the ratio between the first light guide mirror light beam X1, the second light guide mirror light beam Y1 and the third light guide mirror light beam Z1 can be adjusted, making the light guiding easier to control and further enhancing the uniformity of light distribution in the lighting area of ​​the cylindrical lampshade 110.

[0152] At the same time, the greater the inclination of the second light guide mirror light incident surface 5D2, the greater the proportion of the first light guide mirror light incident surface 5D1 relative to the third light guide mirror light incident surface 5D3, and the greater the proportion of the second light beam branch M and the third light beam branch N relative to the first light beam branch L, thereby converting more incident light into the second light guide mirror light beam Y1 and the third light guide mirror light beam Z1, and ultimately enhancing the lighting brightness of the high beam area 110A.

[0153] More specifically, by adjusting the tilt position of the light incident surface 5D2 of the second light guide mirror, the irradiation angle of the second light beam branch M can be adjusted, such as Figure 25As shown, the present application adjusts the irradiation position of the second light beam branch M to the intersection of the first light guide mirror light emitting surface 5B and the second light guide mirror light emitting surface 5C, so that a part of the second light beam branch M is irradiated on the first light guide mirror light emitting surface 5B to generate the second light guide mirror light beam Y1, and the other part is adjusted to irradiate the second light guide mirror light emitting surface 5C to generate the first light guide mirror light beam X1. As the degree of inclination of the light incident surface 5D2 of the second light guide mirror is different, the second light beam branch M can be offset as a whole toward the light exit surface 5B of the first light guide mirror or the light exit surface 5C of the second light guide mirror, thereby adjusting the ratio of the second light beam branch M irradiated to the light exit surface 5B of the first light guide mirror and the light exit surface 5C of the second light guide mirror, and the ratio between the light incident surface 5D1 of the first light guide mirror, the light incident surface 5D2 of the second light guide mirror and the light incident surface 5D3 of the third light guide mirror will also change accordingly. In this way, when facing lighting areas of different heights and diameters, the lighting ratio of the high beam area 110A and the low beam area 110B can also be flexibly adjusted accordingly, thereby more effectively ensuring the uniform brightness of the lighting area.

[0154] In a further embodiment, the light incident surface 5D2 of the second light guide mirror is a curved surface formed by a depression in the bottom of the light guide mirror 5, which enables the generated second light beam branch M to be more convergent and thus more accurately guided to the high beam area 110A.

[0155] In a further embodiment, Figure 25A As shown, the light source 31 is arranged close to the light incident surface 5D3 of the third light guide mirror. The second light guide mirror light incident surface 5D2 includes a second reflection area 5D21 and a second refraction area 5D22 connected to the first light guide mirror light incident surface 5D1. The first light guide mirror light incident surface 5D1, the second reflection area 5D21, the second refraction area 5D22 and the third light guide mirror light incident surface 5D3 are connected in sequence.

[0156] According to optical principles, the incident angle of the incident light emitted by light source 31 at the second reflective region 5D21 will be greater than the incident angle at the second refractive region 5D22. Therefore, by controlling the inclination angle and curvature of the second light guide mirror's light incident surface 5D2, the incident light can be totally reflected at the second reflective region 5D21 and refracted at the second refractive region 5D22. Furthermore, it can be seen that a portion of the third light beam branch N is formed by the incident light being reflected from the second reflective region 5D21, refracted from the first light guide mirror's light incident surface 5D1, and reflected from the light guide mirror's reflective surface 5A. Another portion is formed by the incident light being refracted from the first light guide mirror's light incident surface 5D1 and reflected from the light guide mirror's reflective surface 5A. The second light beam branch M is formed by the incident light being refracted from the second refractive region 5D22.

[0157] The above description is about the lighting module with cylindrical lampshade 110 installed, and the components of the lighting module adapted for cylindrical lampshade 110: fixing assembly S, light source module G and light guide mirror 5. Next, the lighting module with spherical lampshade 120 installed will be analyzed.

[0158] First, the lighting module with the spherical lampshade 120 is introduced.

[0159] like Figure 14 and Figure 18 As shown, different types of lighting modules differ only in the specific selection of the lampshade 100. Therefore, the lighting module with the spherical lampshade 120 installed is structurally the same as the lighting module with the cylindrical lampshade 110 installed as described above. Figure 11 、 Figure 18 and Figure 19 As shown, the lighting module also includes a cantilever 700, a mounting base 600, a light source module G and a fixing assembly S. The spherical lampshade 120 also has a cover opening 100A and a lighting area, which will not be described in detail here.

[0160] The following describes the installation of the fixing assembly S in the spherical lampshade 120 .

[0161] As can be seen from the above, the fixing assembly S is a universal component that can be installed on both the cylindrical lampshade 110 and the spherical lampshade 120. To achieve universality, the fixing assembly S is also designed as follows:

[0162] like Figure 3 、 Figure 16 and Figure 17 As shown, the inner clamping surface 200E includes a first inner clamping surface 200A and a second inner clamping surface 200B respectively provided on two opposite end surfaces of the built-in connecting ring 200, wherein the first inner clamping surface 200A is adapted to the inner mounting surface 100C on the cylindrical lampshade 110, and the second inner clamping surface 200B is adapted to the inner mounting surface 100C on the spherical lampshade 120.

[0163] When the fixing component S needs to be installed on the cylindrical lampshade 110, the internal connecting ring 200 and the external connecting ring 400 can be placed inside and outside the cylindrical lampshade 110 respectively, and the first internal clamping surface 200A is aligned with the internal mounting surface 100C of the cylindrical lampshade 110 to form an adaptation to each other, and then the internal connecting ring 200 and the external connecting ring 400 are connected to each other, and the first internal clamping surface 200A is pressed against the internal mounting surface 100C, and the installation is completed.

[0164] When the fixing assembly S needs to be installed on the spherical lampshade 120, the internal connecting ring 200 and the external connecting ring 400 can be placed inside and outside the spherical lampshade 120 respectively, and the second internal clamping surface 200B is aligned with the internal mounting surface 100C of the spherical lampshade 120 to form an adaptation to each other. Then, the internal connecting ring 200 and the external connecting ring 400 are connected to each other, and the second internal clamping surface 200B is pressed against the internal mounting surface 100C to complete the installation.

[0165] In this way, the versatility of the fixing assembly S can be enhanced by providing the first inner clamping surface 200A and the second inner clamping surface 200B.

[0166] It should be noted here that if Figure 12 and Figure 13 As shown, consistent with the cylindrical lampshade 110 , the internal connecting ring 200 and the external connecting ring 400 are connected to the spherical lampshade 120 through the fastener 500 , which will not be described in detail here.

[0167] Furthermore, Figure 3 、 Figure 16 and Figure 17 As shown, the inner mounting surface 100C of the cylindrical lampshade 110 is a flat surface, and the first inner clamping surface 200A is a plane perpendicular to the rotation axis O of the internal connecting ring 200, so that the two can fit together. The inner mounting surface 100C of the spherical lampshade 120 is a curved surface, and the second inner clamping surface 200B is a rotational curved surface formed by rounding the edges of the internal connecting ring 200, so that the two can fit together.

[0168] It should be pointed out here that the above situation is that the first inner clamping surface 200A is adapted to the cylindrical lampshade 110, and the second inner clamping surface 200B is adapted to the spherical lampshade 120. When the lampshade 100 is of other shapes, the shape of the first inner clamping surface 200A or the second inner clamping surface 200B should also be adaptively changed as the shape of the inner mounting surface 100C of the lampshade 100 changes.

[0169] Further, such as Figure 2 、 Figure 16 and Figure 17 As shown, the bosses provided on the internal connecting ring 200 include a first boss 200D and a second boss 200C. The first boss 200D is provided on the same side as the first inner clamping surface 200A, and the first inner clamping surface 200A surrounds the outside of the first boss 200D. The second boss 200C is provided on the same side as the second inner clamping surface 200B, and the second inner clamping surface 200B surrounds the outside of the second inner clamping surface 200B.

[0170] In this way, when the fixing component S is required to be adapted to the cylindrical lampshade 110, the first inner clamping surface 200A can be turned toward the inner mounting surface 100C of the cylindrical lampshade 110 to achieve the first boss 200D to be inserted into the cover opening 100A; when the fixing component S is required to be adapted to the spherical lampshade 120, the second inner clamping surface 200B can be turned toward the inner mounting surface 100C of the spherical lampshade 120 to achieve the second boss 200C to be inserted into the cover opening 100A.

[0171] In this way, through the mutual cooperation between the first boss 200D or the second boss 200C and the third boss 400B, the cover opening 100A can constrain the fixing component S, thereby achieving radial positioning of the fixing component S.

[0172] Furthermore, as the shape of the lampshade 100 changes, the shape of the external connecting ring 400 should also be adaptively changed, such as Figure 6 and Figure 16 As shown, when the external connecting ring 400 is adapted to the cylindrical lampshade 110, the outer mounting surface 100B is a plane, so the outer clamping surface 400A is also a plane, and the outer shape of the external connecting ring 400 is in the form of a stepped shaft; for example Figure 7 and Figure 17 As shown, when the external connecting ring 400 is adapted to the spherical lampshade 120, the external mounting surface 100B is a curved surface, so the external clamping surface 400A is also a curved surface. The outer side of the external connecting ring 400 presents a circular flange structure, and this circular flange surrounds the outer side of the third boss 400B. Of course, it should be pointed out that the lampshade 100 can also have other shapes. In this case, the external connecting ring 400 and the external clamping surface 400A should also be adaptively adjusted according to the shape of the external mounting surface 100B.

[0173] The light source module G adapted for the spherical lampshade 120 is introduced below.

[0174] As can be seen from the above, the light source module G is a universal component, and the required light distribution element is selected according to the lampshade 100 that needs to be adapted.

[0175] like Figure 30 as well as Figures 35 to 37 As shown, similar to the cylindrical lampshade 110, the light source module G also has a light source module 3 provided with a light source 31. Here, the light distribution element is adapted to the spherical lampshade 120 and is selected as a beam splitter 6.

[0176] like Figure 31 As shown, the spectroscope 6 includes a spectroscope connecting portion 61. The spectroscope connecting portion 61 is arranged around the spectroscope 6, for example, on the outer periphery of the spectroscope 6. In this application, a cone hole is arranged at the center of the spectroscope 6, and the spectroscope connecting portion 61 is arranged in the cone hole.

[0177] like Figures 35 to 37As shown, like the cylindrical lampshade 110, the light source module G also has a lens fixing member 2 and a light source fixing member 4 with a bolt structure. The beam splitter connecting portion 61 is provided with a threaded through-hole. The lens fixing member 2 passes through the beam splitter connecting portion 61 and is threadedly connected to the connecting module 510, thereby fixing the beam splitter 6 to the connecting module 510. The light source module 3 is located between the beam splitter 6 and the connecting module 510. The light source fixing member 4 passes through the light source module 3 and is threadedly connected to the connecting module 510, thereby fixing the light source module 3 to the connecting module 510.

[0178] It should also be noted that the light distribution element of the light source module G can not only be the light guide mirror 5 and the beam splitter 6, but also other types of light distribution elements can be selected depending on the specific shape of the lampshade 100, which will not be detailed here.

[0179] The beam splitter 6 adapted to the spherical lampshade 120 is described below.

[0180] like Figure 30 and Figure 33 As shown, the beam splitter 6 is a light distribution component of the light source module G and is disposed at the bottom of the spherical lampshade 120 and located in the lighting area of ​​the spherical lampshade 120 .

[0181] The lighting area of ​​the spherical lampshade 120 can be divided into a bottom lighting area 120A, a middle lighting area 120B, and a top lighting area 120C, which are connected in sequence. The spectroscope 6 is specifically arranged in the bottom lighting area 120A. As can be seen from the structural characteristics of the spherical lampshade 120, the distance between any distance on the lighting area of ​​the spherical lampshade 120 and the spectroscope 6 will gradually increase from the bottom lighting area 120A to the middle lighting area 120B, and then gradually decrease towards the top lighting area 120C. In this way, if the light source 31 is used to directly illuminate the incident light, the bottom lighting area 120A will not be fully illuminated due to the limited illumination angle of the light source 31, and the brightness will be dim. The middle lighting area 120B will be dim due to its distance from the light source, and the brightness will be bright due to its close distance from the light source. Therefore, the spectroscope 6 is installed in this lighting area to evenly distribute the incident light emitted by the light source 31 to the lighting area of ​​the spherical lampshade 120.

[0182] like Figure 31 and Figure 33 As shown, the beam splitter 6 is an annular lens having a bottom surface and an arc-shaped top surface connected to each other. The arc-shaped top surface and the bottom surface of the beam splitter 6 are connected end to end to form a torus that rotates about the third reference axis O3. The spherical lampshade 120 has a fourth reference axis O4 as a rotation axis. The third reference axis O3 and the fourth reference axis O4 are coaxially arranged to ensure that the beam splitter 6 does not deviate relative to the spherical lampshade 120, thereby preliminarily ensuring uniform brightness across the illuminated area.

[0183] The bottom surface of the beam splitter 6 is recessed into a beam splitter light entrance surface 6C. A light source 31 is positioned within this surface and is capable of emitting incident light toward this surface. A first curved surface 6B1 is located on the side of the top surface away from the third reference axis O3 and connects the second curved surface 6B2 and the bottom surface of the beam splitter 6, respectively. Both the first curved surface 6B1 and the second curved surface 6B2 are curved surfaces convex toward the direction of incident light. The intersection of the first and second curved surfaces 6B1 and 6B2 forms an annular recessed area located on the top surface and circumferentially around the third reference axis O3.

[0184] like Figure 33 、 Figure 34A 、 Figure 34B and Figure 34C As shown, a first section A is drawn through the third reference axis O3. As seen from this section A, the incident light, after being refracted by the beam splitter's incident surface 6C, enters the first curved surface 6B1 and the second curved surface 6B2, respectively. The light refracted by the first curved surface 6B1 forms the first beam X2, while at least part of the light refracted by the second curved surface 6B2 forms the second polarized beam Y22.

[0185] A second extension line X2' is formed, and the second extension line X2' is collinear with the incident light used to form the first spectroscope beam X2. A fourth extension line Y22' is formed, and the fourth extension line Y22' is collinear with the incident light used to form the second polarized light beam Y22.

[0186] Viewed from the first cross-section A, the first beam X2 is offset toward the bottom of the beam splitter 6 relative to the second extension line X2' and emitted away from the third reference axis O3. The second polarized beam Y22 is offset toward the bottom of the beam splitter 6 relative to the fourth extension line Y22' and emitted toward the third reference axis O3. This redistributes the incident light by the beam splitter 6, causing the incident light to be generally offset toward the bottom of the beam splitter 6 after exiting the beam splitter 6. This allows more light to be diverted and directed toward the bottom illuminated area 120A and the middle illuminated area 120B, thereby enhancing the brightness of the bottom illuminated area 120A and the middle illuminated area 120B while reducing the brightness of the top illuminated area 120C. This, in turn, addresses the issue of uniform illumination of the spherical lampshade 120 by the light source 31.

[0187] Further, such as Figure 34D As shown, the curved top surface of the beam splitter 6 also includes a beam splitter reflective surface 6A. This reflective surface 6A is located between the beam splitter incident surface 6C and the third reference axis O3, and connects the second curved surface 6B2 and the bottom surface of the beam splitter 6. The reflective surface 6A is tilted; the distance between the reflective surface 6A and the third reference axis O3 gradually increases from the top to the bottom of the beam splitter 6.

[0188] The incident light is refracted by the beam splitter's incident surface 6C and reflected by the beam splitter's reflective surface 6A, and then enters the first curved surface 6B1 to form a third beam splitter beam Z21, and enters the second curved surface 6B2 to form a fourth beam splitter beam Z22. Thus, by adjusting the reflection angle of the beam splitter's reflective surface 6A and coordinating the refraction of the first curved surface 6B1 and the second curved surface 6B2, the light reflected by the beam splitter's reflective surface 6A can be offset toward the bottom of the beam splitter 6, thereby achieving more light offset and guiding to the illuminated bottom area 120A and the illuminated middle area 120B, further solving the problem of illumination uniformity of the spherical lampshade 120.

[0189] Among the options, Figure 34A As shown, the light incident surface 6C of the beam splitter is a toroidal surface with a curved cross section. For example, the radius of curvature of the light incident surface 6C of the beam splitter gradually increases from the top to the bottom of the beam splitter 6 .

[0190] From the first cross section A, the incident light emitted along the first beam splitting extension line X2' can be refracted by the beam splitter incident surface 6C to form a first refracted beam X2A, and then emitted from the first arc surface 6B1 to form a first beam splitter beam X2.

[0191] In this way, through the mutual cooperation between the light incident surface 6C of the spectrometer and the first curved surface 6B1, the incident light is offset and guided step by step, and finally the first spectrometer beam X2 is formed, that is, more incident light is offset and guided to illuminate the bottom area 120A and the middle area 120B, further enhancing the fill light effect on the bottom area 120A and the middle area 120B, making the brightness of the illuminated area more uniform.

[0192] In a further embodiment, Figure 34B As shown, the second arc surface 6B2 includes a second outer arc segment 6B21. The second outer arc segment 6B21 is located on the side of the second arc surface 6B2 away from the third reference axis O3 and connected to the first arc surface 6B1. The annular recessed area is located between the second outer arc segment 6B21 and the first arc surface 6B1.

[0193] From the first cross section A, the light refracted by the second outer arc segment 6B21 forms a second diffused light beam Y21. A third extended line Y21' is drawn, which is collinear with the incident light beam forming the second diffused light beam Y21 and points toward the illuminated top area 120C.

[0194] It can be seen that a portion of the second diffused light beam Y21 will deviate toward the bottom of the beam splitter 6 and be emitted away from the third reference axis O3, while another portion of the second diffused light beam Y21 will deviate toward the bottom of the beam splitter 6 and be emitted toward the third reference axis O3.

[0195] In this way, the incident light originally irradiated to the illuminated top area 120C along the third extension line Y21' will be diffused to the surrounding area due to the refraction of the second outer arc segment 6B21 and form a second diffused light beam Y21, and then the light will be offset toward the bottom of the spectrometer 6 through the second diffused light beam Y21, so that part of the light can be irradiated to the illuminated middle area 120B, thereby completing the brightness enhancement of the illuminated middle area 120B and the brightness weakening of the illuminated top area 120C, further making the brightness of the illuminated area uniform.

[0196] Further, such as Figure 32 and Figure 34B As shown, the beam splitter's light incident surface 6C is provided with a first light-scattering structure P1. The first light-scattering structure P1 is located at the top of the beam splitter's light incident surface 6C and is arranged sequentially with the second outer arc segment 6B21 along the emission direction of the incident light, that is, along the third extension line Y21'. The first light-scattering structure P1 can be a frosted surface.

[0197] From the first cross section A, after the incident light is refracted by the first scattering structure P1, it will enter the beam splitter 6 and diffuse to the surrounding to form a second scattered light beam Y21A. The second scattered light beam Y21A will then be refracted by the second outer arc segment 6B21 and continue to diffuse to the surrounding to form a second diffused light beam Y21.

[0198] In this way, through the cooperation between the first light-scattering structure P1 and the second outer arc segment 6B21, the incident light along the second light-splitting extension line Y21' is diffused step by step, and the second diffused light beam Y21 obtained thereby has a wider diffusion degree, which can diffuse more incident light to the illuminated area 120B, thereby enhancing the brightness uniformity of the illuminated area.

[0199] Furthermore, Figure 32 As shown, the second curved surface 6B2 and the first curved surface 6B1 have a smooth transition to prevent light from converging in the annular recessed area, which could result in light spots in the illuminated area. As a further solution, a second light-scattering structure P2 is provided in the annular recessed area to evenly diffuse the light emitted by the second light-scattering structure P2, thereby achieving more uniform brightness in the illuminated area. The second light-scattering structure P2 may have a frosted surface.

[0200] In a further embodiment, Figure 34C As shown, the second arc surface 6B2 further includes a second inner arc segment 6B22. The second inner arc segment 6B22 is located on a side of the second arc surface 6B2 close to the third reference axis O3. The second outer arc segment 6B21 connects the first arc surface 6B1 and the second inner arc segment 6B22.

[0201] The incident light is refracted by the beam splitter's incident surface 6C and enters the second inner arc segment 6B22. The second polarized light beam Y22 is generated by the second inner arc segment 6B22 and then emitted toward the third reference axis O3. A fourth extension line Y22' is provided such that the incident light for generating the second polarized light beam Y22 is collinear with the fourth extension line Y22'.

[0202] In this way, the incident light originally emitted along the fourth extension line Y22' will be shifted toward the bottom of the spectrometer 6 to form a second polarized light beam Y22 through the refraction of the second inner arc segment 6B22, that is, more of the original incident light will be shifted and guided to the illuminated middle area 120B, thereby enhancing the brightness of the illuminated middle area 120B and weakening the brightness of the illuminated top area 120C, making the brightness of the illuminated area more uniform.
