The lighting module involved in the multi-headed lamp will be described below, and as described above, can assume different models by mounting different lamp housings 100.

A general description of the lighting module in which the cylindrical lamp housing 110 is installed will be first provided.

Referring to fig. 8, 14 and 15, the lighting module forms a cylindrical wall lamp by mounting a cylindrical lamp housing 110. The lighting module includes a cylindrical lamp housing 110, a cantilever 700, a mount 600, a light source module G, and a fixing member S. The cylindrical lamp cover 110 has a cover opening 100A at the bottom and is hollow inside to form an illumination area.

When the lighting module is assembled, the fixing component S is installed at the cover opening 100A, then the light source module G is placed in the lighting area inside the cylindrical lampshade 110, the light source module G is connected with the fixing component S, then the head end of the mounting base 600 is externally fixed on the fixing component S through the cylindrical lampshade 110, and finally the cantilever 700 is installed at the tail end of the mounting base 600 to complete the installation of the whole lighting module.

It should be noted that the fixing assembly S serves as a connection hinge of the lighting module, so that the pillar-shaped lamp shade 110, the light source module G and the mounting base 600 are connected into a whole through the fixing assembly S. As an optional layout, the light source module G and the mounting base 600 may be respectively fixed on two opposite end surfaces of the fixing assembly S, and the periphery of the fixing assembly S is fixed to the cover opening 100A in a penetrating manner.

It should be noted that the fixing member S is a general member, and is provided for connecting the lamp housing 100 with other parts in the lighting assembly through the fixing member S, that is, the fixing member S can be installed not only in the cylindrical lamp housing 110 described above, but also in other forms of lamp housings 100 such as the globe 120.

The mounting of the fixing member S in the cylindrical lamp housing 110 will be described.

As shown in fig. 4, 8 and 15, the fixing assembly S may include an inner attachment ring 200 and an outer attachment ring 400. The inner connecting ring 200 is disposed inside the cylindrical lamp cover 110, the outer connecting ring 400 is disposed outside the cylindrical lamp cover 110, and the cover opening 100A is located between the inner connecting ring 200 and the outer connecting ring 400.

As shown in fig. 3, 6, and 16, in the area around the cover opening 100A, an inner mounting surface 100C inside the pillar shade 110 and an outer mounting surface 100B outside the pillar shade 110 are provided, respectively. The inner connection ring 200 is provided with an inner holding surface 200E on the end surface thereof, which is fitted to the inner mounting surface 100C. The end face of the external connecting ring 400 is provided with an external clamping face 400A matched with the external mounting face 100B.

As shown in fig. 9 and 16, the inner connecting ring 200 and the outer 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, thereby fixing the fixing assembly S to the pillar lampshade 110 in a clamping manner, and thus the pillar lampshade 110 is connected to the light source module G, the mounting seat 600, and other parts through the fixing assembly S.

It should be noted that the above description is only an implementation specific solution, and as for the connection manner of the fixing assembly S and the cylindrical lamp cover 110, the internal connection ring 200 and the external connection ring 400 may be respectively connected to the cylindrical lamp cover 110, so as to fix the fixing assembly S and the cylindrical lamp cover 110 to each other, which is not described in detail herein.

In alternative embodiments, the light source module G may be fixed to the inner connection ring 200 and the mounting base 600 may be fixed to the outer connection ring 400 in an end face fixing manner, for example, the light source module G may be fixed to the end face of the inner connection ring 200 or the mounting base 600 may be fixed to the end face of the outer connection ring 400 by means of bonding or welding.

As shown in fig. 15, a fixing assembly S may be provided including a connection module 510. The connection module 510 is inserted through the through hole formed by the inner connection ring 200 and the outer connection ring 400. The connection module 510 is connected with the internal connection ring 200 or the external connection ring 400 separately, or connected with both the internal connection ring 200 and the external connection ring 400, so as to be plugged in the cover opening 100A and be fixed in the fixing assembly S in a penetrating manner, for example, the connection module 510 is fixed in a tightening manner by interference fit with the internal 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 seat 600, for example, the light source module G and the mounting seat 600 are fixed to the connection module 510 by means of bolting, bonding, riveting, clamping of a clamping groove, and the like.

More specifically, the outer circumferential surface of the connection module 510 is provided with external threads, and the inner circumferential surface of the inner connection ring 200 and/or the inner circumferential surface of the outer connection ring 400 is provided with internal threads. The connection module 510 is screwed to the inner connection ring 200 and/or the outer connection ring 400 and is inserted and fixed in the fixing assembly S.

Furthermore, the connection module 510 may be configured as a heat dissipation module to dissipate heat accumulated in the pillar lamp housing 110 during operation of the light source module G to the outside of the pillar lamp housing 110, so as to prevent the temperature inside the pillar lamp housing 110 from being too high.

In some embodiments, as shown in fig. 6, the outboard attachment ring 400 may include a third boss 400B. The outer clamping surface 400A is disposed on the same side as the third boss 400B and surrounds the outer side of the third boss 400B. The third boss 400B may be inserted into the cover opening 100A by coupling the inner connection ring 200 and the outer connection ring 400 to each other. Therefore, the third boss 400B is limited by the cover opening 100A, so that the fixing component S is fixed in the radial direction, and the fixing component S is prevented from moving in the radial direction of the cover opening 100A.

Further, a corresponding boss may be provided in the inner connection ring 200, and the boss may be provided on the same side as the inner clamping surface 200E. The inner clamping surface 200E encloses the boss. Thus, when the inner connecting ring 200 and the outer connecting ring 400 are connected to each other, the third protrusion 400B may cooperate with a protrusion provided on the inner connecting ring 200, so as to more effectively achieve radial fixation of the fixing assembly S at the cover opening 100A.

As an alternative to the inner connection ring 200 and the outer connection ring 400, a first connection portion 210 may be provided on the inner connection ring 200 and a second connection portion 410 may be provided on the outer connection ring 400, as shown in fig. 1 and 5. For example, the first connection portion 210 is a buckle disposed on the internal connection ring 200, and the second connection portion 410 is a buckle disposed on the external connection ring 400, so that the internal connection ring 200 is connected to the external connection ring 400; for another example, the first connection portion 210 and the second connection portion 410 are strong adhesive layers that are mutually matched, and the internal connection ring 200 and the external connection ring 400 are connected by mutual adhesion of the two.

As a specific connection scheme adopted in the present application for the internal attachment ring 200 and the external attachment ring 400, the fixing assembly S may further include a fastener 500, as shown in Figs. 9, 10 and 15. The first connection portion 210 and the second connection portion 410 are both through holes. The fasteners 500 sequentially penetrate through the first connection portion 210 and the second connection portion 410, so that the internal connection ring 200 is connected with the external connection ring 400.

Here, the fastening member 500 may be a combination of a bolt and a nut, the first connection portion 210 and the second connection portion 410 are smooth holes penetrating through, and the connection between the internal connection ring 200 and the external connection ring 400 is realized by sequentially penetrating the bolt through the first connection portion 210 and the second connection portion 410 and then connecting the nut with the bolt through a thread; the fastening member 500 may also be a bolt as shown in fig. 9, one of the first connecting portion 210 and the second connecting portion 410 is a threaded through hole, and the other is a threaded hole, and the bolt passes through the threaded through hole and is connected with the threaded hole to realize the connection between the internal connection ring 200 and the external connection ring 400; of course, the fastening member 500 may be a rivet, and the connection between the internal connection ring 200 and the external connection ring 400 is realized by riveting with the rivet.

As an alternative arrangement of the first connection portion 210 and the second connection portion 410, as shown in fig. 1 and 5, the first connection portion 210 is disposed at an inner peripheral region of the built-in connection ring 200, and the inner clamping surface 200E is disposed at an outer peripheral region of the built-in connection ring 200 and surrounds an outer side of the first connection portion 210. The second connection portion 410 is disposed at an inner peripheral region of the external connection ring 400, and the outer clamping surface 400A is disposed at an outer peripheral region of the external connection ring 400 and surrounds an outer side of the second connection portion 410. Thus, the inner peripheral area of the fixing member S is used for connection, and the outer peripheral area is used for holding the cylindrical lamp housing 110, thereby realizing functional division without mutual interference.

Further, as shown in fig. 2 and 6, the first connection portion 210 may be provided on the boss of the inner connection ring 200, and the outer connection ring 400 may be provided on the third boss 400B. So that the structure of the fixing assembly S is more compact.

In some embodiments, as shown in fig. 1 and 5, the outboard connector ring 400 is provided with second heat dissipation holes 420; the built-in connection ring 200 is provided with first heat dissipation holes 220, and the first heat dissipation holes 220 are arranged around the rotation axis O of the built-in connection ring 200. The second heat dissipation holes 420 correspond to the first heat dissipation holes 220 in position and have the same direction. Thus, the heat generated in the cylindrical lamp cover 110 can be dissipated to the outside through the first heat dissipation hole 220 and the second heat dissipation hole 420 in sequence, so as to reduce the temperature in the cylindrical lamp cover 110.

Further, as shown in fig. 1 and 2, since the aperture of the cover opening 100A is smaller than the aperture of the internal connection ring 200, in order to conveniently place the internal connection ring 200 in the cylindrical lamp cover 110, the internal connection ring 200 is configured as an open ring with a first notch 230 formed around the rotation axis O, so that if the internal connection ring 200 is made of a soft material, the internal connection ring 200 can be elastically deformed by applying an external force, and the size of the first notch 230 and the aperture of the internal connection ring 200 are reduced, thereby allowing the internal connection ring 200 to be installed in the cylindrical lamp cover 110 through the cover opening 100A, and facilitating installation. However, if the internal connection ring 200 is made of a hard material, the internal connection ring 200 may be inserted into the pillar shaped lamp cover 110 through the first notch 230, and the internal connection ring 200 may be mounted on the inner mounting surface 100C by being turned inside the pillar shaped lamp cover 110.

Of course, for some open-top versions of the cylindrical lamp cover 110, the built-in connection ring 200 may be installed by placing the built-in connection ring 200 from the top of the cylindrical lamp cover 110, and the built-in connection ring 200 does not need to be open and may be configured as a whole ring structure.

More preferably, built-in go-between 200 adopts the plastic material to make, one of them is external force that applys that can be better like this makes its bore size change to put into the cylindricality lamp shade 110 in, two of it is when built-in go-between 200 and external go-between 400 are connected and are pressed from both sides tight cylindricality lamp shade 110, because the plastic material is softer, can avoid the clamp force when too big, built-in go-between 200 causes the damage to cylindricality lamp shade 110 in the inboard, equally also can adopt the plastic material to make to external go-between 400.

As another alternative, in order to enable the external connection ring 400 to protect the cylindrical lamp cover 110, the external connection ring 400 is made of a metal material which is not easy to deform, and meanwhile, the flexible pad 300 shown in fig. 4 and 9 is additionally installed, the flexible pad 300 is usually made of materials such as silica gel, and is applied to the external clamping surface 400A, so that through the buffering of the flexible pad 300, the external connection ring 400 can be well prevented from damaging the cylindrical lamp cover 110 at the outer side when the clamping force is too large.

The light source module G adapted to the cylindrical lamp housing 110 will be described.

As shown in fig. 20 and 24, the light source module G is located in the illumination area of the pillar lamp cover 110, and is used for emitting light to irradiate the pillar lamp cover 110 and irradiating the light to the outside through the pillar lamp cover 110.

As shown in fig. 26, the light source module G includes a light source module 3, a light source 31 is disposed on the light source module 3, and the light source module G emits light through the light source 31. The light source 31 may be specifically an LED dot matrix light, and may be a circular array layout adapted to the characteristics of the revolving structure of the pillar lampshade 110.

As shown in fig. 27 to 29, the light source module 3 is provided with a light distribution element that is fitted to the globe 100 and can uniformly distribute the light emitted from the light source 31 to the illumination area of the globe 100. For example, the lampshade 100 is used as the cylindrical lampshade 110, and the light distribution element is adapted to the cylindrical lampshade 110 by the light guide mirror 5.

Furthermore, the light source module G further includes a lens holder 2 and a light source holder 4. The lens holder 2 is used to connect the light guide mirror 5 with the fixing member S (specifically, the connection module 510), and the light source module 3 is located between the light guide mirror 5 and the fixing member S. The light source fixing member 4 is used for connecting the light source module 3 with the fixing component S. Thus, the light source module G can be fixed to the connection module 510.

In a further embodiment, as shown in fig. 21 and 26, the light guide mirror 5 is provided with a light guide mirror connecting portion 51, and the light guide mirror connecting portion 51 is a burring 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.

As shown in fig. 27 to 29, the lens holder 2 and the light source holder 4 may be provided as bolts. Corresponding threaded holes are provided in the connection module 510. The lens fixing piece 2 is inserted into the light guide mirror connecting part 51 and connected with the threaded hole on the connecting module 510, so that the light guide mirror 5 is fixed on the connecting module 510; the light source fixing member 4 is inserted into the light source module 3 and connected to the screw hole of the connection module 510, so that the light source module 3 is fixed to the connection module 510.

It should be pointed out simultaneously that light source module G also is general, and the accessible chooses for use different grading components, realizes carrying out the adaptation with the lamp shade 100 that corresponds, for example above-mentioned light source module G realizes with cylindricality lamp shade 110 adaptation through choosing for use light guide mirror 5, and light source module G also can realize with globe lampshade 120 adaptation through choosing for use spectroscope 6. The light source module G whose light distribution element is the spectroscope 6 will be described in detail later.

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

As shown in fig. 24A and 24, the light guide mirror 5 is provided at the bottom of the cylindrical lamp cover 110 and is located in the illumination area of the cylindrical lamp cover 110.

The illumination area of the cylindrical lamp cover 110 includes a low beam area 110B close to the light guide 5 and a high beam area 110A far from the light guide 5. It can be known from the structural characteristics of the cylindrical lampshade 110 that the distance between any position on the illumination area of the cylindrical lampshade 110 and the light guide lens 5 gradually increases from the low beam area 110B to the high beam area 110A, so that if the light source 31 is directly used for irradiating the incident light, the illumination of the low beam area 110B is slightly bright, and the illumination of the high beam area 110A is slightly dark, so the light guide lens 5 is arranged to uniformly distribute the incident light emitted by the light source 31 to the illumination area of the cylindrical lampshade 110

As shown in fig. 21 and 24, the light guide 5 is an annular lens that rotates about the first reference axis O1, and has a tapered hole formed along the first reference axis O1. The aperture of the taper hole becomes gradually larger toward the bottom of the light guide mirror 5. The pillar shade 110 has a second reference axis O2 as a rotation axis; the first reference axis O1 is coaxially arranged with the second reference axis O2 to ensure that the light guide 5 is not displaced with respect to the cylindrical lamp cover 110, preliminarily ensuring uniformity of the luminance of the illumination area.

As shown in fig. 21, the inner peripheral surface of the light guide mirror 5 forms a light guide mirror reflection surface 5A, the top surface of the light guide mirror 5 forms a first light guide mirror light-emitting surface 5B, and the outer peripheral surface of the light guide mirror 5 forms a second light guide mirror light-emitting surface 5C; the light guide mirror light reflecting surface 5A, the first light guide mirror light emitting surface 5B, the second light guide mirror light emitting surface 5C and the bottom surface of the light guide mirror 5 are connected end to form a ring surface; the light reflecting surface 5A of the light guide mirror is a hole surface of the taper hole. The bottom surface of the light guide mirror 5 is concavely provided with a light guide mirror light incident surface 5D; the light source 31 is disposed in the light incident surface 5D of the light guide mirror.

As shown in fig. 24A, fig. 24 and fig. 25, the incident light from the light source 31 is incident into the light guide mirror 5 through the light guide mirror light incident surface 5D, and then is incident into the first light guide mirror light emergent surface 5B to form a second light guide mirror light beam Y1, and is incident into the second light guide mirror light emergent surface 5C to form a first light guide mirror light beam X1, and is reflected into the first light guide mirror light emergent surface 5B through the light guide mirror light reflecting surface 5A to form a third light guide mirror light beam Z1.

As shown in fig. 24A and 25, the second reference axis O2 is a second cross section B, and is a first extension Z1' of the incident light ray entering the light guide mirror reflection surface 5A. When viewed from the second cross section B, the first extension line Z1' passes through the second reference axis O2 and enters the low beam region 110B, and the third light guide mirror beam Z1 enters the high beam region 110A away from the second reference axis O2.

Thus, by setting the inclination angle and controlling the profile of the light reflecting surface 5A of the light guide mirror, part of the incident light (i.e. the first extension line Z1') that originally enters the low beam region 110B can be reflected to the high beam region 110A (i.e. the third light guide mirror light beam Z1), so that the brightness of the low beam region 110B is weakened, the brightness of the high beam region 110A is enhanced, and the problem of uniformity of illumination of the light source 31 on the cylindrical lampshade 110 is solved.

In summary, by the arrangement of the light guide mirror 5, the light refracted by the light exit surface 5B of the first light guide mirror enters the portion of the illumination area far 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 enter the high beam area 110A; and the light refracted by the light outgoing surface 5C of the second light guiding mirror is incident into the portion of the illumination area close to the light guiding mirror 5, that is, the first light guiding mirror light beam X1 is incident into the low beam area 110B, so that the incident light is redistributed, and the illumination of the illumination area of the cylindrical lampshade 110 is uniform.

Further, as shown in fig. 21 and 25, the light guide mirror reflection surface 5A is a curved surface recessed toward the bottom of the light guide mirror 5. Like this, through the setting of this concave surface, can make light guide mirror reflection surface 5A reflect incident light simultaneously and assemble, and cooperate light guide mirror reflection surface 5A's slope design, can make the light that light guide mirror reflection surface 5A reflects shine to first light guide mirror light-emitting surface 5B with higher degree of assembling, and then make the third light guide mirror light beam Z1 who forms can be more accurate by leaded light to far-reaching light region 110A, the reinforcing is to the luminance reinforcing effect in far-reaching light region 110A.

Further, as shown in fig. 21, the first light guide mirror light exit surface 5B is a curved surface that is protruded and is inclined with respect to the first reference axis O1. The protruding direction of the light-emitting surface 5B of the first light guide mirror is directed from the bottom of the light guide mirror 5 to the top. The first light guide mirror light-emitting surface 5B is obliquely arranged, and the first light guide mirror light-emitting surface 5B 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 inclination angle of the first light guide mirror light outgoing surface 5B, both the second light guide mirror light beam Y1 and the third light guide mirror light beam Z1 can be more accurately guided to the high beam region 110A, so that the brightness of the high beam region 110A is enhanced. The light emitting surface 5C of the second light guiding mirror can be a cylindrical surface or a conical surface to save the manufacturing cost, as long as the incident light can finally reach the low beam region 110B.

Further, as shown in fig. 22 and 23, the light-scattering structures P are disposed on the light-emitting surface 5B of the first light-guiding mirror and the light-emitting surface 5C of the second light-guiding mirror, and the light-scattering structures P may be surfaces formed by frosting, so that the light is diffused when being irradiated by the light-scattering structures P, and the uniformity of the light distribution in the illumination area of the cylindrical lamp cover 110 can be enhanced.

It should be noted that, by providing the light scattering structure P on the light-emitting surface 5B of the first light guide mirror, the light can be prevented from being excessively condensed by the light-reflecting surface 5A of the light guide mirror to form a light spot in the high beam region 110A.

Further, as shown in fig. 22 and 23, the first light guide mirror light exiting surface 5B includes a first light guide mirror light scattering area 5B1 and a first light guide mirror light exiting area 5B 2. The second light guide mirror light-emitting surface 5C, the first light guide mirror light-scattering area 5B1, the first light guide mirror light-emitting area 5B2 and the light guide mirror light-reflecting surface 5A are connected in sequence. The light scattering structure P is disposed on the second light guide mirror light-emitting surface 5C and the first light guide mirror light-scattering area 5B 1.

The design of dividing the light-emitting surface 5B of the first light guide mirror into functional areas can enable light to be refracted and emitted with different optical effects, specifically, the light can be prevented from converging to form light spots by arranging the light-scattering area 5B1 of the first light guide mirror, and the light-emitting area 5B2 of the first light guide mirror can prevent the light from being excessively diffused and being dark in brightness after being transmitted to the high beam area 110A.

In some embodiments, as shown in fig. 25 and 25A, the top surface of the light guide mirror in-plane 5D forms a second light guide mirror in-plane 5D2, the inner peripheral surface of the light guide mirror in-plane 5D forms a first light guide mirror in-plane 5D1, and the outer peripheral surface of the light guide mirror in-plane 5D forms a third light guide mirror in- plane 5D 3.

The first light guide mirror light incident surface 5D1 is close to the first reference axis O1, the third light guide mirror light incident surface 5D3 surrounds the outer side of the first light guide mirror light incident surface 5D1, and the second light guide mirror light incident surface 5D2 is connected with the first light guide mirror light incident surface 5D1 and the third light guide mirror light incident surface 5D3 respectively. The second light guide mirror light incident surface 5D2 is obliquely arranged, and the distance from the first reference axis O1 gradually increases from the top to the bottom of the light guide mirror 5.

After the incident light beam enters the light guide mirror 5, the incident light beam is 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 light reflecting surface 5A in sequence to form a third light beam branch N.

The first light beam branch L is refracted by the light exit surface 5C of the second light guide mirror to form a first light guide mirror light 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 than the first light beam branch L, and the second light beam branch M is refracted by the second light guide mirror light incident surface 5D2 to form a second light guide mirror light beam Y1. The third light beam branch N is refracted by the first light guide mirror light-emitting surface 5B to form a third light guide mirror light beam Z1.

Thus, the proportion of 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 by changing the proportion 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, so that light guide is easier to control, and the distribution uniformity of light rays in the illumination area of the cylindrical lampshade 110 is further enhanced.

Meanwhile, the larger the inclination degree of the second light guide mirror light incident surface 5D2 is, the larger the proportion of the first light guide mirror light incident surface 5D1 with respect to the third light guide mirror light incident surface 5D3 is, and the larger the proportion of the second light beam branch M and the third light beam branch N with respect to the first light beam branch L is, so that more incident light rays are converted into the second light guide mirror light beam Y1 and the third light guide mirror light beam Z1, and finally the illumination brightness of the high beam region 110A is enhanced.

More specifically, the illumination angle of the second light beam branch M can be adjusted by adjusting the inclined position of the light incident surface 5D2 of the second light guide mirror, as shown in fig. 25, the illumination position of the second light beam branch M is adjusted to be located at the boundary position between the light emergent surface 5B of the first light guide mirror and the light emergent surface 5C of the second light guide mirror, so that a part of the second light beam branch M illuminates the light emergent surface 5B of the first light guide mirror to generate a second light guide mirror light beam Y1, and the other part of the second light beam branch M is adjusted to illuminate the light emergent surface 5C of the second light guide mirror to generate a first light guide mirror light beam X1. With the difference of the inclination degree of the second light guiding mirror light incident surface 5D2, the second light beam branch M can be shifted to the first light guiding mirror light emergent surface 5B or the second light guiding mirror light emergent surface 5C, so as to adjust the ratio of the second light beam branch M irradiating the first light guiding mirror light emergent surface 5B and the second light guiding mirror light emergent surface 5C, and the ratio between the first light guiding mirror light incident surface 5D1, the second light guiding mirror light incident surface 5D2 and the third light guiding mirror light incident surface 5D3 will change accordingly, so that when facing illumination areas with different heights and calibers, the illumination ratio of the high beam area 110A and the low beam area 110B can be flexibly adjusted along with the illumination areas, thereby more effectively ensuring the uniform brightness of the illumination areas.

In a further embodiment, the second light incident surface 5D2 is a curved surface formed by being concave toward the bottom of the light guide mirror 5, so that the generated second light beam branch M can be converged to a higher degree, and thus can be guided to the high beam region 110A more accurately.

In a further embodiment, as shown in FIG. 25A, the light source 31 is disposed near the third light guiding mirror in- plane 5D 3. The second light guide mirror light incident surface 5D2 comprises a second reflection region 5D21 and a second refraction region 5D22 which are connected with the first light guide mirror light incident surface 5D1, and the first light guide mirror light incident surface 5D1, the second reflection region 5D21, the second refraction region 5D22 and the third light guide mirror light incident surface 5D3 are sequentially connected

As can be seen from the optical principle, the incident angle of the incident light from the light source 31 in the second reflection region 5D21 is greater than the incident angle in the second refraction region 5D22, so that the incident light can be totally reflected in the second reflection region 5D21 and refracted in the second refraction region 5D22 by controlling the inclination angle and curvature of the light incident surface 5D2 of the second light guide mirror. Furthermore, it can be seen that a part of the third light beam branch N is formed by the incident light being sequentially reflected by the second reflection region 5D21, refracted by the first light guide mirror light incident surface 5D1, and reflected by the light guide mirror light reflecting surface 5A, and another part is formed by the incident light being sequentially refracted by the first light guide mirror light incident surface 5D1, and reflected by the light guide mirror light reflecting surface 5A. The second beam branch M is formed by the incident light being refracted by the second refracting area 5D 22.

What has been described above is about the lighting module in which the cylindrical lamp housing 110 is installed, and the components of the lighting module that are adapted to the cylindrical lamp housing 110: the fixing component S, the light source module G and the light guide mirror 5. Next, the lighting module with the globe 120 mounted thereon is analyzed.

First, a lighting module in which the globe 120 is installed will be described.

As shown in fig. 14 and 18, the different types of lighting modules only differ in the specific choice of the lamp housing 100, so that the lighting module with the globe 120 mounted thereon has the same structure as the lighting module with the cylindrical lamp housing 110 described above, for example, as shown in fig. 11, 18 and 19, and also includes the cantilever 700, the mounting seat 600, the light source module G and the fixing member S. The globe 120 is also provided with a cover aperture 100A and an illumination area, which will not be described in detail herein.

The mounting of the fixing member S in the globe 120 will be described.

As described above, the fixing member S is a universal member and can be mounted on both the pillar lampshade 110 and the globe lampshade 120, and in order to achieve the universal property, the fixing member S is further designed as follows:

as shown in fig. 3, 16 and 17, the inner holding surface 200E includes a first inner holding surface 200A and a second inner holding surface 200B respectively disposed on two opposite end surfaces of the built-in connection ring 200, wherein the first inner holding surface 200A is adapted to the inner mounting surface 100C of the cylindrical lamp housing 110, and the second inner holding surface 200B is adapted to the inner mounting surface 100C of the spherical lamp housing 120.

When the fixing assembly S needs to be installed on the pillar shaped lamp cover 110, the internal connection ring 200 and the external connection ring 400 can be respectively placed inside and outside the pillar shaped lamp cover 110, the first internal clamping surface 200A faces the internal installation surface 100C of the pillar shaped lamp cover 110 to form an adaptation to each other, and then the internal connection ring 200 and the external connection ring 400 are connected with each other, and the first internal clamping surface 200A is pressed against the internal installation surface 100C, so that the installation is completed immediately.

When the fixing assembly S needs to be installed on the globe 120, the internal connection ring 200 and the external connection ring 400 may be respectively disposed inside and outside the globe 120, and the second internal clamping surface 200B is aligned with the internal installation surface 100C of the globe 120 to form an adaptation to each other, and then the internal connection ring 200 and the external connection ring 400 are connected to each other, and the second internal clamping surface 200B is pressed against the internal installation surface 100C, thereby completing the installation.

In this way, by the provision of the first inner clamping surface 200A and the second inner clamping surface 200B, the versatility of the fixing member S can be enhanced.

It should be noted that, as shown in fig. 12 and 13, the inner connection ring 200 and the outer connection ring 400 are connected to the globe 120 by the fastening members 500 in accordance with the cylindrical lamp cover 110, and will not be described in detail.

Further, as shown in fig. 3, 16 and 17, the inner mounting surface 100C of the cylindrical lamp cover 110 is a flat surface, and the first inner holding surface 200A is a flat surface perpendicular to the rotation axis O of the inner connection ring 200, so that the inner holding surface and the inner holding surface are fitted to each other. The inner mounting surface 100C of the globe 120 is an arc surface, and the second inner holding surface 200B is a revolving arc surface formed by rounding the edge of the inner connection ring 200, so that the two are adapted to each other.

It should be noted that, in the above case, the first inner clamping surface 200A is adapted to the cylindrical lampshade 110, and the second inner clamping surface 200B is adapted to the globe 120, and when the lampshade 100 is in other shapes, the shape of the first inner clamping surface 200A or the second inner clamping surface 200B should be adapted to the shape of the inner mounting surface 100C of the lampshade 100.

Further, as shown in fig. 2, 16 and 17, the bosses provided on the built-in connection ring 200 include a first boss 200D and a second boss 200C. The first boss 200D is disposed on the same side as the first inner clamping surface 200A, and the first inner clamping surface 200A surrounds the outer side of the first boss 200D. The second boss 200C is disposed on the same side as the second inner clamping surface 200B, and the second inner clamping surface 200B surrounds the outer side of the second inner clamping surface 200B.

Thus, when the fixing component S is required to be adapted to the pillar-shaped lamp shade 110, the first boss 200D can be arranged in the shade opening 100A in a penetrating manner by facing the first inner clamping surface 200A to the inner mounting surface 100C of the pillar-shaped lamp shade 110; when the fixing component S is required to be adapted to the globe 120, the second boss 200C can be inserted into the cover opening 100A by facing the second inner clamping surface 200B to the inner mounting surface 100C of the globe 120

Therefore, the first boss 200D or the second boss 200C is matched with the third boss 400B, so that the cover opening 100A can restrain the fixing component S, and the fixing component S can be positioned in the radial direction.

Further, the external connection ring 400 has an adaptive shape according to the different external shapes of the lamp cover 100, for example, as shown in fig. 6 and 16, when the external connection ring 400 is adapted to the cylindrical lamp cover 110, the external mounting surface 100B is a plane, so the external clamping surface 400A is also a plane, and the external connection ring 400 has a stepped shaft shape; for example, as shown in fig. 7 and 17, when the external connection ring 400 is fitted to the globe 120, the external mounting surface 100B is an arc surface, so the external clamping surface 400A is also an arc surface, the outer side of the external connection ring 400 has an annular flange structure, and the annular flange surrounds the outer side of the third protrusion 400B. It should be noted that the lampshade 100 may have other shapes, and the external connection ring 400 and the external clamping surface 400A may be adapted according to the shape of the external mounting surface 100B.

The light source module G adapted to the globe 120 will be described.

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 which is adapted as required.

As shown in fig. 30 and fig. 35 to 37, the light source module G also includes the light source module 3 provided with the light source 31, similarly to the pillar lamp cover 110. The light distribution element is matched with the spherical lampshade 120 and is selected as a spectroscope 6.

As shown in fig. 31, the spectroscope 6 includes a spectroscope connection portion 61. The spectroscope connection part 61 is disposed at a periphery of the spectroscope 6, for example, at an outer periphery of the spectroscope 6, and a taper hole is disposed at a center of the spectroscope 6, and the spectroscope connection part 61 is disposed in the taper hole.

As shown in fig. 35 to 37, the light source module G further includes a lens holder 2 and a light source holder 4 having a bolt structure, like the pillar lamp cover 110. The spectroscope connecting part 61 is provided with a threaded through hole, the lens fixing piece 2 penetrates through the spectroscope connecting part 61 and is in threaded connection with the connecting module 510, and the spectroscope 6 is fixed on the connecting module 510; the light source module 3 is located between the spectroscope 6 and the connection module 510, and the light source fixing member 4 is threaded through the light source module 3 and is connected with the connection module 510, so that the light source module 3 is fixed on the connection module 510.

Meanwhile, it should be noted that the light distribution element of the light source module G may be a light guide mirror 5 and a light splitter mirror 6, and may be other types of light distribution elements according to different specific forms of the lamp shade 100, which will not be described in detail herein.

The beam splitter 6 adapted to the globe 120 is described below.

As shown in fig. 30 and 33, the beam splitter 6 is a light distribution element of the light source module G, is disposed at the bottom of the globe 120, and is located in the illumination area of the globe 120.

The illumination area of the globe 120 may be divided into an illumination bottom area 120A, an illumination middle area 120B, and an illumination top area 120C, which are sequentially connected. The beam splitter 6 is specifically disposed in the illumination bottom area 120A. It can be known from the structural characteristics of the globes 120 that the distance between any distance on the illumination area of the globes 120 and the spectroscope 6 is gradually increased from the bottom illumination area 120A to the middle illumination area 120B and then gradually decreased to the top illumination area 120C, so that if the light source 31 is used for direct irradiation of incident light, the bottom illumination area 120A cannot be sufficiently irradiated due to the limitation of the irradiation angle of the light source 31, and the brightness is too dark in the middle illumination area 120B due to the distance from the light source, and the top illumination area 120C is sufficiently irradiated due to the distance from the light source, and therefore, the spectroscope 6 is installed in the illumination area to uniformly distribute the incident light emitted by the light source 31 to the illumination area of the globes 120.

As shown in fig. 31 and 33, the spectroscope 6 is an annular lens and has a bottom surface and an arc top surface connected to each other; the arc top surface and the bottom surface of the spectroscope 6 are connected end to form an annular surface which rotates around a third reference axis O3. The globe 120 has a fourth reference axis O4 as a rotation axis; the third reference axis O3 is coaxially arranged with the fourth reference axis O4 to ensure that the beam splitter 6 is not shifted with respect to the globe 120, and to primarily ensure uniformity of the brightness of the illumination area.

The bottom surface of the spectroscope 6 is concavely provided with a spectroscope light-in surface 6C, and the light source 31 is arranged in the spectroscope light-in surface 6C and can emit incident light rays to the spectroscope light-in surface 6C. The first cambered surface 6B1 is located on the side of the arc top surface far from the third reference axis O3 and is respectively connected with the second cambered surface 6B2 and the bottom surface of the beam splitter 6. The first arc surface 6B1 and the second arc surface 6B2 are both curved surfaces protruding towards the emitting direction of the incident light, and the intersection of the first arc surface 6B1 and the second arc surface 6B2 forms an annular concave area which is located on the top surface of the arc and rotates around the third reference axis O3.

As shown in fig. 33, 34A, 34B and 34C, the third reference axis O3 is taken as a first cross section a, and when viewed from the first cross section a, the incident light is refracted by the light splitter light incident surface 6C and then enters the first arc surface 6B1 and the second arc surface 6B2, respectively. The light refracted by the first cambered surface 6B1 forms a first beam splitter beam X2, and at least part of the light refracted by the second cambered surface 6B2 forms a second polarized beam Y22.

As a second extension line X2 ', the second extension line X2' is collinear with the incident light ray for forming the first beam splitter beam X2. As a fourth extension line Y22 ', the fourth extension line Y22' is collinear with the incident light for forming the second polarized light beam Y22.

When viewed from the first cross section a, the first beam splitter beam X2 will be shifted toward the bottom of the beam splitter 6 with respect to the second extension line X2' and exit away from the third reference axis O3; the second polarized light beam Y22 is deviated toward the bottom of the beam splitter 6 with respect to the fourth extension line Y22' and emitted toward the third reference axis O3. Therefore, the incident light is redistributed by the beam splitter 6, the incident light is deflected towards the bottom of the beam splitter 6 after being emitted by the beam splitter 6, more light is deflected and guided to the illumination bottom area 120A and the illumination middle area 120B, the brightness of the illumination bottom area 120A and the illumination middle area 120B is enhanced, the brightness of the illumination top area 120C is weakened, and the problem of illumination uniformity of the light source 31 to the globe 120 is solved.

Further, as shown in fig. 34D, the arc top surface of the beam splitter 6 further includes a beam splitter light reflecting surface 6A. The light reflecting surface 6A of the beam splitter is located between the light incident surface 6C of the beam splitter and the third reference axis O3, and is connected to the second arc surface 6B2 and the bottom surface of the beam splitter 6 respectively. The reflecting surface 6A of the spectroscope is obliquely arranged; the distance between the light reflecting surface 6A of the beam splitter and the third reference axis O3 gradually increases from the top to the bottom of the beam splitter 6.

The incident light is refracted by the light-in surface 6C of the light splitter and reflected by the light-reflecting surface 6A of the light splitter, and the incident light respectively enters the first cambered surface 6B1 to form a third light splitter beam Z21 and enters the second cambered surface 6B2 to form a fourth light splitter beam Z22. Therefore, by adjusting the reflection angle of the light reflecting surface 6A of the light splitter and matching with the refraction of the first cambered surface 6B1 and the second cambered surface 6B2, the light reflected by the light reflecting surface 6A of the light splitter can be deflected towards the bottom of the light splitter 6, so that more light is deflected and guided to the illumination bottom area 120A and the illumination middle area 120B, and the problem of illumination uniformity of the globe 120 is further solved

In an alternative, as shown in fig. 34A, the light entering surface 6C is a ring surface with a curved cross section, for example, the radius of curvature of the light entering surface 6C is gradually increased from the top to the bottom of the beam splitter 6.

When viewed from the first cross section a, an incident light ray emitted along the first light splitting extension line X2' may be refracted by the light incident surface 6C of the light splitter to form a first refracted light beam X2A, and then emitted from the first arc surface 6B1 to form a first light splitter light beam X2.

Therefore, through the mutual matching of the light incident surface 6C of the light splitter and the first cambered surface 6B1, the incident light rays are shifted and guided step by step, and finally, a first light splitter beam X2 is formed, namely, more incident light rays are shifted and guided to the illumination bottom area 120A and the illumination middle area 120B, the light supplement effect of the illumination bottom area 120A and the illumination middle area 120B is further enhanced, and the brightness of the illumination area is more uniform.

In a further embodiment, as shown in fig. 34B, the second arcuate surface 6B2 includes a second outer arcuate segment 6B 21. The second outer arc segment 6B21 is located on a side of the second arc face 6B2 away from the third reference axis O3 and connects to the first arc face 6B 1. The annular recessed region is located between the second outer arc segment 6B21 and the first arc face 6B 1.

When viewed from the first cross-section A, light refracted through the second outer arc segment 6B21 will form a second diffused light beam Y21. As a third extension line Y21 ', the third extension line Y21 ' is collinear with the incident light for forming the second diffused light beam Y21, and the third extension line Y21 ' is directed to the illuminated ceiling region 120C.

It can be seen that a portion of the second diffused light beam Y21 will be deflected towards the bottom of the beam splitter 6 and exit away from the third reference axis O3, and another portion of the second diffused light beam Y21 will be deflected towards the bottom of the beam splitter 6 and exit towards the third reference axis O3.

Thus, the incident light originally irradiated to the illumination top area 120C along the third extension line Y21' is diffused and expanded to the surroundings by the refraction of the second outer arc segment 6B21 to form the second diffused light beam Y21, and then the light is deflected toward the bottom of the beam splitter 6 by the second diffused light beam Y21 to realize that part of the light is irradiated to the illumination middle area 120B, thereby completing the brightness enhancement of the illumination middle area 120B and the brightness attenuation of the illumination top area 120C, and further making the brightness of the illumination area uniform.

Further, as shown in fig. 32 and 34B, the light splitter light incident surface 6C is provided with a first light scattering structure P1. The first light scattering structure P1 is located on the top of the light incident surface 6C of the beam splitter, and is sequentially arranged with the second outer arc segment 6B21 along the emitting direction of the incident light, i.e. along the third extension line Y21'. The first light scattering structure P1 may be a sanded surface.

When viewed from the first cross section a, the incident light is refracted by the first light scattering structure P1, and then enters the beam splitter 6 and is diffused to the periphery to form a second diffused light beam Y21A, and the second diffused light beam Y21A is refracted by the second outer arc segment 6B21 and is further diffused to the periphery to form a second diffused light beam Y21.

In this way, the first light scattering structure P1 and the second outer arc section 6B21 are matched with each other, so that the incident light along the second light splitting extension line Y21' is gradually diffused, and the obtained second diffused light beam Y21 has wider diffusivity, and can diffuse more incident light to the middle illumination area 120B, so that the brightness uniformity of the illumination area is enhanced.

Further, as shown in fig. 32, the second curved surface 6B2 and the first curved surface 6B1 are smoothly transited to prevent the light from converging in the annular concave area to cause the light spot in the illumination area. As a further proposal, the annular concave region is provided with the second light scattering structure P2 to uniformly diffuse the light emitted by the second light scattering structure P2, so as to make the brightness of the illumination region more uniform. The second light scattering structure P2 may be a sanded surface.

In a further embodiment, as shown in fig. 34C, the second arcuate surface 6B2 further includes a second inner arcuate segment 6B 22. The second inner arc segment 6B22 is located on the side of the second arc face 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, respectively.

The incident light is refracted by the light-entering surface 6C of the light splitter and enters the second inner arc section 6B22, and passes through the second inner arc section 6B22 to form a second polarized light beam Y22, and the second polarized light beam Y22 is emitted toward the third reference axis O3. The fourth extension line Y22 'is provided, and the incident light for generating the second polarized light beam Y22 is collinear with the fourth extension line Y22'.

Therefore, the incident light originally emitted along the fourth extension line Y22' is deflected to the bottom of the beam splitter 6 by the refraction of the second inner arc segment 6B22 to form a second polarized light beam Y22, i.e., more original incident light is deflected and guided to the illumination middle area 120B, so that the brightness of the illumination middle area 120B is enhanced, the brightness of the illumination top area 120C is weakened, and the brightness of the illumination area is more uniform.
