Description

Technical Field

[0001] The present invention relates to the technical field of optical equipment, and in particular to a sleeve assembly and a lamp. Background Art

[0002] As material conditions improve, people's demands for light output quality and personalized products are gradually increasing. Light output quality depends on the design of optical solutions.

[0003] The optical components of common spotlight products on the market cannot be partially disassembled after being combined with other peripheral components of the lamp body and can only be replaced as a whole. After some customers purchase a set of such products, if they want to change the optical effect of the product during use, they need to replace the entire set of products, doubling the time and cost investment. Summary of the invention

[0004] The invention discloses a sleeve assembly and a lamp, so as to solve the problem that the existing spotlight products have a high cost when changing the optical effect.

[0005] The embodiment of the present invention is achieved as follows:

[0006] Based on the above-mentioned purpose, an embodiment of the present invention discloses a sleeve assembly that can be universally assembled in lamp body assemblies of different sizes, including a first cylinder and a first light distribution element that can be detachably assembled to the first cylinder, and the first cylinder is provided with a first mating portion for mating with the first light distribution element and a second mating portion for mating with the lamp body assembly.

[0007] Based on the above purpose, an embodiment of the present invention further discloses a lamp, including a light source module, a sleeve assembly as described above, and a lamp body assembly that accommodates and combines the sleeve assembly.

[0008] The technical solution adopted by the present invention can achieve the following beneficial effects:

[0009] The sleeve assembly provided by the present invention includes a detachable first barrel and a first light distribution element. The first barrel can be used as a container to accommodate the first light distribution element and position the first light distribution element. The change of the optical effect of the optical product is usually achieved by changing the degree of the first light distribution element. The existing sleeve is installed on the lamp as a whole. When the optical effect needs to be changed, the sleeve can only be replaced as a whole. The optical product is a high-precision product, which takes a lot of time to replace, and its own production cost is also high. When the user wants to obtain multiple different models of sleeves, it is necessary to invest more costs. The first light distribution element and the first barrel of the sleeve assembly provided by the present invention are detachably combined. When the optical effect of the optical product needs to be changed, it is only necessary to remove the first light distribution element and then replace it with a first light distribution element with a different degree to complete the change of the optical effect of the optical product. The operation is simple, time-saving and labor-saving, and only a set of first light distribution elements with multiple degrees needs to be purchased, without the need to hold other components in multiple sleeve assemblies, thereby greatly saving costs.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] The technical solutions disclosed in various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] Please refer to Figures 1 to 3 An embodiment of the present invention discloses a sleeve assembly 10 , which includes a first barrel 100 and a first light distribution element 200 .

[0028] The first barrel 100 is used as a basic accommodating component for installing the first light distribution element 200, and is provided with a first matching portion 110 for matching with the first light distribution element 200, a second matching portion 120 for matching with the lamp body assembly 20, and a third matching portion for matching with the reflector.

[0029] The first light distribution element 200 is an important component for changing the optical effect of the optical product. It is detachably mounted on the top of the first barrel 100 and detachably combined with the first matching portion 110 on the first barrel 100 to facilitate replacement of the first light distribution element 200 .

[0030] The first light distribution element 200 can be produced in a set, and each set of the first light distribution element 200 can include a plurality of first light distribution elements 200 with different degrees, such as the commonly used first light distribution elements 200 with 10 degrees, 24 degrees, 36 degrees and 60 degrees. When there are special requirements, first light distribution elements 200 with special degrees can also be added. At the same time, the first light distribution element 200 can be produced as a standard part, that is, the structure and size of the first light distribution element 200 are standardized, so that each first light distribution element 200 with different degrees is consistent in structure and size, so that the first light distribution elements 200 with different degrees can be installed on the first cylinder 100. At the same time, when a first light distribution element 200 with a certain degree in a set of first light distribution elements 200 is damaged, only the first light distribution element 200 with the damaged degree can be supplemented without purchasing another set, thereby greatly saving costs.

[0031] Since in the implementation mode of the present embodiment, the first light distribution element 200 is detachably connected to the first barrel 100, when it is necessary to change the optical effect of the optical product, it is only necessary to replace the first light distribution element 200 without replacing the entire sleeve assembly 10, thereby further realizing cost savings. At the same time, due to the reduction in changes, the operating steps are further simplified, saving time and effort.

[0032] In some implementations of this embodiment, the first matching portion 110 may be located at the top end inside the first cylinder 100 , and the first matching portion 110 and the first light distribution element 200 may be snap-fitted or threadedly coupled.

[0033] The first light distribution element 200 may be a sheet-shaped lens, and a matching structure 210 matching with the first matching portion 110 is disposed on the first light distribution element 200 .

[0034] When the first matching portion 110 and the first light distribution element 200 are snap-fitted, please refer to Figures 4 to 6The first matching portion 110 can be a card point on the inner wall of the first cylinder 100, and the card point is a protrusion on the inner wall of the first cylinder 100. At this time, the matching structure 210 can be a card slot, that is, a card slot is set at a position corresponding to the side wall of the first light distribution element 200, and the card point is connected to the card slot, which can position and fix the first light distribution element 200. When separation is required, the first light distribution element 200 can be directly pushed to remove the first light distribution element 200 from the first cylinder 100.

[0035] The first matching portion 110 may include a plurality of clamping points, which are arranged at intervals along the circumference of the first cylinder 100 . Correspondingly, the matching structure 210 may include a plurality of clamping slots, which correspond one-to-one to the plurality of clamping points.

[0036] The matching structure 210 may be a radial depression along the first light distribution element 200, and its extension direction is parallel to the axis of the first light distribution element 200. The matching structure 210 has two ends along its extension direction, the end with the slot facing the top of the first light distribution element 200 is the first end, and the end with the slot facing the bottom of the first light distribution element 200 is the second end.

[0037] The second end of the matching structure 210 is a closed end, that is, the second end of the matching structure 210 does not extend to the bottom surface of the first light distribution element 200. In this case, there are two ways to set the first end of the matching structure 210:

[0038] The first one is that when the first end of the matching structure 210 extends to the top surface of the first light distribution element 200, the first end of the matching structure 210 is in an open state. After the first matching portion 110 is inserted into the matching structure 210, the first light distribution element 200 may continue to slide down along the axis direction of the first cylinder 100 because the first matching portion 110 cannot prevent the first light distribution element 200 from continuing to descend. In order to avoid this situation, a protrusion 130 can be provided on the inner wall of the first cylinder 100, the protrusion 130 is located below the card point, and the protrusion 130 and the card point are spaced apart, and the distance between the protrusion 130 and the card point in the axial direction of the first cylinder 100 is equal to the distance between the second end of the matching structure 210 and the bottom surface of the first light distribution element 200. In this way, the protrusion 130 can be used to support the first light distribution element 200 to prevent the first light distribution element 200 from continuing to fall. At the same time, the protrusion 130 and the card point are used to form a card connection with the first light distribution element 200, so that the connection between the first light distribution element 200 and the first cylinder 100 can be made more firmly and stably.

[0039] The protrusion 130 can be provided in plurality, and the plurality of protrusions 130 are arranged at intervals along the circumference of the first cylinder 100 . The plurality of protrusions 130 can form a relatively balanced support for the first light distribution element 200 in all directions, so that the first light distribution element 200 can work better and avoid tilting.

[0040] Preferably, the plurality of protrusions 130 may be connected to each other so that the protrusions 130 form a ring along the first cylinder 100 , which is more convenient during installation and the first light distribution element 200 can be more stable.

[0041] Furthermore, the protrusion 130 and the first barrel 100 may be integrally formed, that is, the thickness of the first barrel 100 at this position is greater than the thickness of the top thereof, thereby forming the protrusion 130 , which can facilitate production and processing.

[0042] The second type is that when the first end of the matching structure 210 does not extend to the top surface of the first light distribution element 200 (not shown in this scheme), the first end of the matching structure 210 is in a closed state. After the first matching portion 110 is inserted into the matching structure 210, the second end of the matching structure 210 can prevent the first light distribution element 200 from falling off the first cylinder 100 upwards, and at the same time, the first end of the matching structure 210 can prevent the first light distribution element 200 from continuing to slide down along the axis direction of the first cylinder 100, thereby completing the positioning and fixing of the first light distribution element 200.

[0043] In this case, the setting of the protrusion 130 can form a match with the first matching portion 110 to form a snap connection with the first light distribution element 200, so that the first light distribution element 200 can be more firmly and stably connected to the first barrel 100. The first light distribution element 200 can be fixed by the matching of the protrusion 130 and the first matching portion 110, so the length of the matching structure 210 can be greater than the thickness of the first matching portion 110, which is the length of the first matching portion 110 along the axis direction of the first barrel 100.

[0044] In some cases, when the protrusion 130 is not provided on the first cylinder 100, the matching structure 210 can be used to complete the fixation of the first light distribution element 200. At this time, the length of the matching structure 210 needs to be equal to the thickness of the first matching portion 110. When the first matching portion 110 is inserted into the matching structure 210, the first matching portion 110 and the matching structure 210 form a transition fit, which can also position and fix the first light distribution element 200.

[0045] In some implementations of the present embodiment, since the first light distribution element 200 will be squeezed during the installation process and will inevitably shift, a structure for positioning, such as a positioning groove 220 and a positioning block 140, may be provided on the first light distribution element 200 and the first cylinder 100. In the first cylinder 100 and the first light distribution element 200, one is provided with a positioning groove 220, and the other is provided with a positioning block 140 that cooperates with the positioning groove 220, thereby preventing the first light distribution element 200 from shifting during the installation process.

[0046] The positioning groove 220 can be set on the first light distribution element 200, or can be set on the first barrel 100. When the positioning groove 220 is set on the first light distribution element 200, the two ends of the positioning groove 220 extend to the top surface and the bottom surface of the first light distribution element 200 respectively. At this time, the positioning block 140 is set on the first barrel 100, and the first end of the positioning block 140 extends to the top surface of the first barrel 100, and the second end of the positioning block 140 can be extended to the top surface of the protrusion 130, or the second end of the positioning block 140 is spaced from the top surface of the protrusion 130. At the same time, the width of the positioning groove 220 is equal to the width of the positioning block 140. When the first light distribution element 200 is installed on the first barrel 100, the positioning block 140 can be inserted into the positioning groove 220 to limit the first light distribution element 200 to prevent it from shaking or shifting.

[0047] When the positioning groove 220 is provided on the first barrel 100, the two ends of the positioning groove 220 extend to the top surface of the first barrel 100 and the top surface of the protrusion 130 respectively. At this time, the positioning block 140 is provided on the first light distribution element 200, and the first end of the positioning block 140 extends to the bottom surface of the first light distribution element 200. The second end of the positioning block 140 may not extend to the top surface of the first light distribution element 200, and the positioning function can also be completed. In order to avoid the formation of a gap between the first light distribution element 200 and the first barrel 100, which affects the optical effect, the second end of the positioning block 140 can be extended to the top surface of the first light distribution element 200.

[0048] It should be noted that the positioning groove 220 or the positioning block 140 on the first light distribution element 200 needs to be spaced apart from the slot opening, and the positioning block 140 or the positioning groove 220 on the first barrel 100 needs to be spaced apart from the card point.

[0049] When the first light distribution element 200 is installed on the first barrel 100, the bottom of the first light distribution element 200 is installed from the top of the first barrel 100 toward the first barrel 100, and the position of the first light distribution element 200 is adjusted so that the positioning groove 220 is aligned with the positioning block 140. At this time, the matching structure 210 is exactly aligned with the first matching portion 110, and then the first light distribution element 200 is pressed downward. When the first light distribution element 200 is inserted into the first barrel 100 from the top of the first barrel 100, the side wall of the first light distribution element 200 squeezes the first matching portion 110. When the first light distribution element 200 moves a certain distance along the axial direction of the first barrel 100, the first matching portion 110 is inserted into the matching structure 210, and the installation of the first light distribution element 200 is completed.

[0050] When the first light distribution element 200 needs to be removed from the first barrel 100 , it is only necessary to apply a thrust to the bottom of the first light distribution element 200 to separate the first light distribution element 200 from the top of the first barrel 100 .

[0051] As a preferred implementation of this embodiment, the second end of the matching structure 210 can be set as a first slope 230, and the first slope 230 is inclined inward along the recessed direction of the card slot. The distance between one end of the first slope 230 located at the bottom of the card slot and the bottom surface of the first light distribution element 200 is greater than the distance between one end of the first slope 230 located at the slot of the matching structure 210 and the bottom surface of the first light distribution element 200. In this way, when separating the first light distribution element 200 from the first barrel 100, it can be more labor-saving. At the same time, it can also avoid causing greater damage to the first light distribution element 200 or the first barrel 100, thereby ensuring that the first light distribution element 200 and the first barrel 100 can have a longer service life under the premise of frequent replacement of the first light distribution element 200.

[0052] As a preferred implementation manner of this embodiment, the inclination angle of the first slope 230 can be set to 45 degrees to 60 degrees. When the first slope 230 increases from 45 degrees, the connection strength between the first light distribution element 200 and the first barrel 100 gradually decreases, and the force required to separate the first light distribution element 200 from the first barrel 100 also gradually decreases, and the damage caused to the first light distribution element 200 and the first barrel 100 during separation also gradually decreases; when the angle of the first slope 230 exceeds 60 degrees, it may cause the connection between the first light distribution element 200 and the first barrel 100 to be too loose, and then cause the first light distribution element 200 to fall off during use. Therefore, the angle of the first slope 230 should be less than or equal to 60 degrees.

[0053] A structure that matches the first inclined surface 230 can also be provided on the first matching portion 110. The structure can be another inclined surface or a spherical surface, so that the cross-section of the cardan point is triangular or semicircular. This not only makes it easier to separate the first light distribution element 200 from the first barrel 100, but the first matching portion 110 of this shape can also make it easier to install the first light distribution element 200 on the first barrel 100.

[0054] Setting the first matching portion 110 as a card point and setting the matching structure 210 as a card slot is only one implementation of this embodiment. In some other implementations, setting the first matching portion 110 as a card slot and setting the matching structure 210 as a card point is also possible.

[0055] When the first matching portion 110 and the first light distribution element 200 are threadedly connected, an internal thread can be set on the top of the first barrel 100. In this case, the internal thread is the first matching portion 110. Then, an external thread matching the internal thread is set on the outer peripheral wall of the first light distribution element 200. The external thread is the matching structure 210, so that a threaded connection is formed between the optical element and the first barrel 100. The first light distribution element 200 can be directly screwed to achieve installation or disassembly between the first barrel 100, which is simple and convenient.

[0056] The first cylinder 100 provided in this embodiment can be an anti-glare cylinder, which is composed of anti-glare glass. Anti-glare glass is also called anti-reflection glass or non-reflection glass, which is a glass with a special surface treatment. The principle is to process high-quality glass on one or both sides so that it has a lower reflectivity than ordinary glass, and reduce the reflectivity of light to less than 1%, thereby reducing the interference of ambient light, improving the clarity and energy of the picture, reducing screen reflection, and making the image clearer and more realistic. Let the viewer enjoy a better visual effect. Anti-glare glass reduces the reflectivity of the glass surface to ≤2%, the transmittance ≥80, and the glossiness ≥60.

[0057] See also Figure 8 In some implementations of the present embodiment, an adjustable angle kit 180 for emitted light may be further provided in the first cylinder 100. The adjustable angle kit 180 for emitted light may include at least a group of optical elements that can rotate relative to each other, wherein at least one optical element is a polarizing lens to change the angle of emitted light.

[0058] The exit light angle adjustable kit 180 includes at least a first optical element 181 and a second optical element 182, one of the first optical element 181 and the second optical element 182 can be a polarizing optical element, or both can be polarizing optical elements. Taking the rotation stroke of the first optical element 181 as 360 degrees as an example, if one of the first optical element 181 and the second optical element 182 is a polarizing optical element, then no matter which position the first optical element 181 rotates to, the exit light passing through the light distribution component is polarized and refracted, that is, the light distribution component of the embodiment of the present invention is a polarizing component. At this time, if the deflection angle of the first optical element 181 is large, the illumination trajectory of the light emitted by the light source through the light distribution component may be circular, that is, it cannot illuminate the front of the light distribution component. If the first optical element 181 and the second optical element 182 are both polarizing optical elements, at certain angles, the light distribution component can be a non-polarizing lens.

[0059] It should be noted that, in the embodiment of the present invention, the first optical element 181 is rotatably arranged relative to the second optical element 182, which means that, in actual use, the first optical element 181 can be driven to rotate and the second optical element 182 can remain stationary, or the first optical element 181 can be driven to remain stationary and the second optical element 182 can be rotated, depending on which light distribution path of the light distribution component can be changed.

[0060] In some implementations of the present embodiment, the sleeve assembly 10 also includes a second barrel 300, which is installed at the bottom of the first barrel 100, and the second barrel 300 is sleeved inside the first barrel 100. The second barrel 300 is an additional component of the first barrel 100. After it is installed on the first barrel 100, it generally does not need to be disassembled. However, in some special cases, when the second barrel 300 needs to be disassembled from the first barrel 100, the second barrel 300 can also be removed from the first barrel 100.

[0061] See also Figure 5 and Figure 7 In some implementations of this embodiment, the first barrel 100 is provided with a first slot 160, and the second barrel 300 is provided with a block 310, which is engaged with the first slot 160. In order to facilitate the installation of the second barrel 300 and the first barrel 100, a second inclined surface 330 may be provided on the block 310, and a third inclined surface 170 may be provided at the bottom of the first barrel 100.

[0062] In some cases, the angle between the second barrel 300 and the first barrel 100 needs to be adjusted. Therefore, a first handle 320 can be set at the bottom of the second barrel 300. Through the first handle 320, a tangential force can be more easily applied to the second barrel 300, so that the second barrel 300 can be more easily rotated relative to the first barrel 100, thereby achieving the angle adjustment between the second barrel 300 and the first barrel 100.

[0063] In some implementations of this embodiment, the second matching portion 120 is located outside the first cylinder 100, and the second matching portion 120 can be a buckle, a thread, or a screw locking structure.

[0064] See also Figures 9 to 11 The embodiment of the present invention further discloses a lamp body assembly 20 that can be connected to a sleeve assembly, which includes a first lamp body 400, a second lamp body 500, a light source module 600 and a primary optical element 700.

[0065] The first lamp body 400 and the second lamp body 500 are assembled and can rotate relatively. The second lamp body 500 is used to accommodate various components such as the sleeve assembly 10, and a circuit for power supply can be arranged on the top of the first lamp body 400.

[0066] The light source module 600 is mounted on the top of the first lamp body 400 , and the light source module 600 is located inside the first lamp body 400 .

[0067] The primary optical element 700 is installed on the top of the second lamp body 500 so that the primary optical element 700 is located between the first lamp body 400 and the second lamp body 500. When the first lamp body 400 and the second lamp body 500 are installed together, the top of the primary optical element 700 abuts against the light source module 600.

[0068] A sleeve assembly mating portion 510 is also formed inside the second lamp body 500, and the sleeve assembly mating portion 510 is used to be detachably combined with the second mating portion 120. The sleeve assembly 10 and the second lamp body 500 are detachably connected, and the sleeve assembly 10 is installed with a first light distribution element 200 for adjusting the optical effect. When the optical effect of the optical product needs to be adjusted, it is only necessary to remove the sleeve assembly 10 provided with the first light distribution element 200, and then replace it with a sleeve assembly 10 with a first light distribution element 200 of a different degree, so as to change the optical effect of the optical product, without having to replace other positions of the lamp, which is simple to operate, saving time and effort.

[0069] The sleeve assembly 10 and the lamp body assembly 20 are connected in a detachable manner. When the optical effect of the optical product needs to be adjusted, it is only necessary to remove the sleeve assembly 10 provided with the first light distribution element 200 from the lamp body assembly 20, and then replace the first light distribution element 200 on the sleeve assembly 10. After replacing a first light distribution element 200 with a different degree, the sleeve assembly 10 is installed on the lamp body assembly 20 to complete the change of the optical effect of the optical product. There is no need to replace other parts of the lamp. The operation is simple, saving time and effort.

[0070] In the implementation manner of this embodiment, the lamp body assembly 20 and the first barrel 100 can be connected by means of a buckle and a slot. The cooperation between the buckle and the second slot is relatively simple, and when producing the lamp body assembly 20 and the first barrel 100, it is also convenient to add a second matching part 120 and a second slot to the lamp body assembly 20 or the first barrel 100.

[0071] The second matching portion 120 can be a buckle or a slot. When the second matching portion 120 is a buckle, the sleeve assembly matching portion 510 can be a second slot. When the second matching portion 120 is a slot, the sleeve assembly matching portion 510 is a buckle that matches it. Since the lamp body assembly 20 is a basic structure for accommodating components, the structure of the lamp body assembly 20 should not be too complicated. Therefore, the second slot can be selected to be set on the lamp body assembly 20. Setting the second slot on the lamp body assembly 20 will not make the structure of the lamp body assembly 20 complicated, and will not affect the installation of subsequent components. As the first barrel 100 is a component accommodated in the lamp body assembly 20, it is more convenient to squeeze the second matching portion 120 during installation, so that the first barrel 100 and the lamp body assembly 20 can be connected more easily. At the same time, this can also reduce the vibration generated during installation, which can protect more precise and delicate electrical components.

[0072] Of course, in other embodiments, it is also possible to set the second matching portion 120 on the inner wall of the lamp body assembly 20 and the second clamping groove on the outer wall of the first barrel 100. In other embodiments, it is also possible to set the second clamping groove and the second matching portion 120 on the lamp body assembly 20 and set the second matching portion 120 and the second clamping groove at the corresponding position of the first barrel 100.

[0073] In some implementations of this embodiment, the second matching portion 120 may include a connecting portion 121 and a clamping portion 122 .

[0074] The first end of the connection part 121 is connected to the first barrel 100, and the second end of the connection part 121 is a free end in a suspended state, and the second end of the connection part 121 can be set to be slightly inclined in a direction away from the first barrel 100, so that when the second end of the connection part 121 is squeezed, it will generate an elastic force radially outward along the first barrel 100. On the one hand, this elastic force can make the connection between the first barrel 100 and the lamp body more firmly, and on the other hand, this elastic force indicates that the connection part 121 itself can withstand a certain elastic deformation. When separating the first barrel 100 and the lamp body assembly 20, it is only necessary to squeeze the second end of the connection part 121 so that the second end of the connection part 121 rests on the side wall of the first barrel 100, and the first barrel 100 can be separated from the lamp body assembly 20, which is simple to operate and saves time and effort.

[0075] The clamping portion 122 can be installed at the second end of the connecting portion 121, and the clamping portion 122 is located on the side of the connecting portion 121 away from the first cylinder 100. In this way, under the action of the elastic force of the connecting portion 121, the clamping portion 122 can be well sent into the second clamping groove on the lamp body to form a clamping connection.

[0076] In this embodiment, a fourth inclined surface 123 can be provided on the clamping portion 122, and the fourth inclined surface 123 is located at the top of the clamping portion 122. The setting of the fourth inclined surface 123 makes the thickness of the end of the clamping portion 122 away from the connecting portion 121 smaller than the thickness of the connection between the clamping portion 122 and the connecting portion 121. In this way, during installation, the fourth inclined surface 123 can be used to allow the connecting portion 121 to overcome the elastic force and shrink to the side wall of the first cylinder 100, thereby facilitating the first cylinder 100 to enter the lamp body assembly 20.

[0077] In order to ensure the reliability of the connection between the first cylinder 100 and the lamp body, the bottom surface of the clamping portion 122 needs to be perpendicular to the connecting portion 121, or there is only a small angle between the bottom surface of the clamping portion 122 and the connecting portion 121, and the bottom wall of the second clamping groove on the lamp body assembly 20 also needs to be perpendicular to the axis of the lamp body assembly 20, which will form a more stable clamping connection between the clamping portion 122 and the second clamping groove.

[0078] The width of the top wall of the second slot can be greater than the projection width of the fourth slope 123 on the axis of the first barrel 100, so that the clamping portion 122 can be positioned at the top of the clamping portion 122, thereby preventing the first barrel 100 from being too deep in the lamp body.

[0079] A fifth inclined surface 511 cooperating with the fourth inclined surface 123 may be provided at the bottom of the lamp body. The cooperation between the fourth inclined surface 123 and the fifth inclined surface 511 can better shrink the connecting portion 121, thereby facilitating the installation between the sleeve assembly 10 and the lamp body assembly 20.

[0080] In some implementations of this embodiment, the second mating portion 120 may include at least two clips, and the at least two clips are arranged at intervals along the circumference of the first cylinder 100. The at least two clips can support the first cylinder 100 from different positions respectively, thereby ensuring the stability of the first cylinder 100.

[0081] Correspondingly, the lamp body assembly 20 may be provided with at least two second card slots, and the number of the second card slots is set corresponding to the number of the second matching parts 120, and each second matching part 120 is correspondingly connected to a second card slot. In some more preferred embodiments, multiple second card slots may be connected to form a second card slot in an annular shape on the lamp body assembly 20, so that during installation, there is no need to align the second matching parts 120 on the first barrel 100 with the second card slot on the lamp body assembly 20, and the first barrel 100 can be installed toward the lamp body assembly 20 from any angle, thereby making the installation simpler and faster.

[0082] As a preferred implementation of this embodiment, the second matching portion 120 may include three buckles, and the three buckles are evenly arranged along the circumference of the first cylinder 100 .

[0083] In some implementations of this embodiment, a second handle 150 can also be set at the bottom of the first barrel 100. Since the first barrel 100 is installed in the lamp body assembly 20 from any angle, it is sometimes necessary to fine-tune the angle of the first barrel 100. The fine-tuning method is generally to allow the first barrel 100 to rotate along its axis relative to the lamp body assembly 20. Providing the second handle 150 at the bottom of the first barrel 100 can make the rotation of the first barrel 100 more convenient. When adjustment is required, the second handle 150 can be used as a fulcrum to facilitate the user to apply force.

[0084] The second handle 150 may be provided as one or more. In this embodiment, one second handle 150 is provided as an example for explanation. The second handle 150 may be provided at the bottom of the first barrel 100 and protrude from the bottom of the sleeve assembly 10 to facilitate application of force. At the same time, when separating the first barrel 100 from the lamp body assembly 20, since the first barrel 100 is located inside the lamp body assembly 20, it is not convenient to pull the first barrel 100 out of the lamp body assembly 20 after squeezing the connecting portion 121. The provision of the second handle 150 can facilitate the user's hand or tool to apply force, thereby pulling the first barrel 100 out of the lamp body assembly 20.

[0085] The second handle 150 may be connected to the first end of the connection portion 121, and the connection between the second handle 150 and the connection portion 121 is installed on the outer wall of the first barrel 100. In some embodiments, the second handle 150 is suspended. At the same time, when the second end of the connection portion 121 swings, the second handle 150 will swing accordingly. Correspondingly, when the second handle 150 is squeezed, the second end of the connection portion 121 will also swing with the swing of the second handle 150. In this case, when the first barrel 100 and the lamp body assembly 20 are disassembled, the end of the second handle 150 away from the connection portion 121 can be dragged outward, which will drive the second end of the connection portion 121 toward the first barrel 100 and separate the clamping portion 122 from the second clamping groove. At this time, the second handle 150 can be directly pulled to pull the first barrel 100 out of the lamp body assembly 20, making the operation more coherent and concise.

[0086] In order to avoid mutual interference between the first handle 320 and the second handle 150, the second handle 150 can be slightly tilted radially outward along the first cylinder 100, so that the angle of the first cylinder 100 and the second cylinder 300 can be adjusted more conveniently without affecting the overall function of the sleeve assembly 10.

[0087] The second matching portion 120 and the second handle 150 may both be disposed on the first barrel 100 , and the connection between the second matching portion 120 and the first handle 320 may be located at the bottom of the first barrel 100 .

[0088] The above are only some implementations when the second matching portion 120 is a buckle. In some other implementations, the lamp body assembly 20 and the first cylinder 100 may be directly connected by threaded connection or screw locking.

[0089] In some implementations of the present embodiment, the sleeve assembly 10 also includes a third mating portion for mating with the second light distribution element 40, the third mating portion is arranged at an end of the first cylinder 100 away from the first mating portion 110, and extends beyond the end of the first cylinder 100, and the third mating portion is integrally arranged with the second mating portion 120.

[0090] In some implementations of this embodiment, the lamp body assembly 20 that can be connected to the sleeve assembly 10 also includes a primary optical element accommodating portion 520, which is integrally arranged with the sleeve assembly matching portion 510, and the primary optical element 700 is connected to the primary optical element accommodating portion 520.

[0091] See also Fig.12 The second lamp body 500 includes a top wall and a peripheral wall, the top wall and the peripheral wall are surrounded to form a receiving space, and the sleeve assembly matching portion 510 extends into the receiving space.

[0092] An annular embedded structure can be arranged in the second lamp body 500, and the embedded structure can be arranged coaxially with the second lamp body 500. Two mutually connected cavities are arranged on the embedded structure, and the two cavities are arranged in sequence along the axial direction of the embedded structure. The cavity located at the top of the embedded structure is the primary optical element accommodating part 520, which can be used to accommodate and install the primary optical element 700. The sleeve assembly matching part 510 is located in the cavity at the bottom of the inner cavity structure. When the sleeve assembly 10 is placed in the cavity at the bottom of the embedded structure, the sleeve condition is fixed by the sleeve assembly matching part 510, and at this time, the light-emitting surface of the primary optical element 700 faces the first light distribution element 200.

[0093] When the primary element is installed in the primary optical element accommodating portion 520 and the sleeve assembly 10 is installed in the sleeve assembly matching portion 510 , the light emitting surface of the primary optical element 700 is arranged just toward the light distribution element in the sleeve assembly 10 .

[0094] In some implementations of this embodiment, the primary optical element 700 is a collimating lens, and the light distribution element may be a polarizing lens.

[0095] See also Fig.13 The embodiment of the present invention further discloses a lamp, including a male-female structure 30, a light source module 600, a primary optical component, a second light distribution element 40, a face frame 50, and the above-mentioned sleeve assembly 10 and lamp body assembly 20, wherein the male-female structure 30 is installed on the top of the lamp body, the light source module 600, the primary optical component, the sleeve assembly 10, the second light distribution element 40 and the face frame 50 are sequentially arranged along the axis of the lamp body assembly 20, the reflector is installed on the face frame 50, and the second light distribution element 40 is connected to the first cylinder 100 through a third matching portion.

[0096] The second light distribution element 40 in this embodiment may be a reflector or other optical elements.

[0097] In some implementations of this embodiment, the third matching portion may be integrally provided with the second matching portion 120 .

[0098] The sleeve assembly 10 and the lamp body assembly 20 in the lamp provided in the present embodiment are connected in a detachable manner. When the optical effect of the optical product needs to be changed, it is only necessary to remove the sleeve assembly 10 provided with the first light distribution element 200, and then replace it with a sleeve assembly 10 with a first light distribution element 200 of a different degree, so as to complete the change of the optical effect of the optical product. There is no need to replace other positions of the lamp, which is simple to operate, saves time and effort, and only needs to purchase a set of sleeve assemblies 10 containing first light distribution elements 200 of various degrees, without having to hold multiple lamp body assemblies 20, thereby greatly saving costs. Compared with the volume of the lamp body assembly 20, the sleeve assembly 10 can also reduce the occupied space.

[0099] The above embodiments of the present invention focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.
