Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to an illumination angle adjustment structure and an illumination angle adjustable lighting fixture. Background Technology

[0002] Angle-adjustable luminaires are those designed to allow users to adjust the illumination angle as needed. This design enables the luminaire to adapt to different lighting requirements, improving flexibility and comfort. With continuous updates in luminaire design, omnidirectional adjustable luminaires have emerged. These omnidirectional adjustable luminaires can adjust the illumination angle 360 ​​degrees, further enhancing flexibility. For example, utility model patent application CN202310312501.2 describes a design where the light-transmitting component rotates relative to the mounting component, and the mounting component rotates relative to the lamp housing. This restricts the rotation direction of the light-transmitting component to be different from the rotation direction of the light-transmitting component itself. This allows the light-transmitting component to rotate independently in two directions, effectively achieving 360-degree rotation of the optical lens. Furthermore, the optical lens deflects the light emitted from the light source, achieving 360-degree adjustment of the luminaire's illumination angle. However, it still has the following problems:

[0003] 1. The lamp needs to be rotated in two directions to achieve a 360-degree adjustment of the illumination angle, which makes the adjustment inconvenient.

[0004] 2. During rotation, the two parts that are rotating relative to each other are in surface contact, resulting in poor rotational smoothness.

[0005] Therefore, the ease and smoothness of adjusting the illumination angle of the lamps still need to be improved. Utility Model Content

[0057] The present application provides a light fixture with adjustable illumination angle. The illumination angle adjusting structure in the light fixture with adjustable illumination angle is used to assemble the optical module at the lamp shell so that the light emitted by the light source module enters the optical module. Further, the optical module is arranged apart from the lamp shell and the light source module.

[0058] In order to better understand the light fixture with adjustable illumination angle of the present application, the illumination angle adjusting structure will be further explained as follows:

[0059] Please refer to Figures 1 to 3 , the illumination angle adjusting structure 10 of an embodiment includes a point contact 10a. Please also refer to Figure 12 , the point contact 10a is arranged around the peripheral wall of the optical module 40 and connected with the optical module 40. The point contact 10a and the optical module 40 are accommodated together at the lamp shell 20. The point contact 10a is in point contact with the inner wall of the lamp shell 20, and the side of the point contact 10a away from the optical module 40 is rollably connected to the inner wall of the lamp shell 20 in any direction, so that the optical module 40 can rotate relative to the lamp shell 20 to change the light direction when the light passes through the optical module 40 and is emitted.

[0060] The irradiation angle adjusting structure 10 described above makes the point contact piece 10a wrap around the peripheral wall of the optical module 40 and connect with the optical module 40, that is, the optical module 40 is connected with the lamp shell 20 through the point contact piece 10a, and the point contact piece 10a is in point contact and abutment with the inner wall of the lamp shell 20, that is, the indirect point contact and abutment of the optical module 40 with the lamp shell 20 is realized. The side of the point contact piece 10a away from the optical module 40 is rollably connected with the inner wall of the lamp shell 20 in any direction, so that the point contact piece 10a drives the optical module 40 to roll relative to the inner wall of the lamp shell 20, and the optical module 40 is rotated relative to the light source module 30 in any direction, the 360-degree point contact rotation of the optical module 40 relative to the light source module 30 is realized, and the deflection of the light emitted by the light source module 30 through the optical module 40 is realized. The smoothness of the 360-degree adjustment of the irradiation angle of the irradiation angle adjustable lamp 10A is improved, and the user can complete the 360-degree adjustment of the irradiation angle of the irradiation angle adjustable lamp 10A by applying force to the optical module 40 and forcing the point contact piece 10a to roll relative to the inner wall of the lamp shell 20, thereby improving the adjustment convenience of the irradiation angle of the irradiation angle adjustable lamp 10A.

[0061] It should be noted that the point contact piece can be fixedly connected to the lamp shell, and the connection with the optical module is realized in an abutment manner.

[0062] In order to better understand the irradiation angle adjustable lamp of the present application, the irradiation angle adjustable lamp of the present application will be further explained in combination with the irradiation angle adjusting structure as follows:

[0063] Please refer to Figures 1 to 3 The irradiation angle adjustable lamp 10A of an embodiment includes a lamp shell 20, a light source module 30, an optical module 40, and the irradiation angle adjusting structure 10 of any of the embodiments described above. The light source module 30 is arranged in the lamp shell 20. The point contact piece 10a wraps around the peripheral wall of the optical module 40 and connects with the optical module 40, and the point contact piece 10a and the optical module 40 are accommodated in the lamp shell 20 together, so that the light emitted by the light source module 30 enters the optical module 40. The point contact piece 10a is in point contact and abutment with the inner wall of the lamp shell 20, and the side of the point contact piece 10a away from the optical module 40 is rollably connected with the inner wall of the lamp shell 20 in any direction, so that the optical module 40 can be rotated relative to the lamp shell 20 to change the light emission direction of the light emitted through the optical module 40.

[0064] The irradiation angle adjustable lamp 10A described above adopts the irradiation angle adjusting structure 10, and the adjustment convenience and smoothness of the irradiation angle of the irradiation angle adjustable lamp 10A are improved.

[0065] It should be noted that the point contact member is rollably connected to the inner wall of the lamp shell in any direction away from the side of the optical module, which can be understood as follows: the side of the point contact member for abutting against the inner wall of the lamp shell is a spherical surface to allow the point contact member to roll in any direction relative to the inner wall of the lamp shell, and the point contact member is arranged around the peripheral wall of the optical module, so that the point contact member drives the optical module to roll relative to the inner wall of the lamp shell to make the optical module rotate relative to the light source module in any direction, that is, the optical module is realized 360-degree rotation relative to the light source module, and the light emitted by the light source module is deflected by the optical module to realize 360-degree adjustment of the illumination angle of the lamp.

[0066] It should be further noted that since the point contact member allows the optical module to rotate relative to the light source module in any direction, the user can quickly adjust the illumination angle of the lamp by 360 degrees when applying force to the optical module and forcing the point contact member to roll relative to the inner wall of the lamp shell, effectively improving the convenience of adjusting the illumination angle of the lamp. In addition, since the point contact member and the inner wall of the lamp shell are in point contact rolling, the smoothness of adjusting the illumination angle of the lamp is better improved.

[0067] It should be noted that since the optical module is limited in the lamp shell by the point contact member and rotates relative to the light source module, that is, the rotation of the optical module is limited within the lamp shell, the user can better control the light entrance surface of the optical module to be arranged opposite to the light source module on the basis of adjusting the rotation angle of the optical module to effectively realize that the light emitted by the light source module enters the light entrance surface of the optical module, and the light further exits through the light exit surface of the optical module, thereby effectively controlling the light exit effect of the lamp with adjustable illumination angle. That is, when the optical module is arranged on the inner wall of the lamp shell by rolling the point contact member, the rotation angle of the optical module can be effectively controlled by the user, and the propagation direction of the light emitted by the optical module can be fully adjusted, thereby effectively adjusting the illumination angle of the lamp with adjustable illumination angle.

[0068] Please refer to Figure 2 , Figure 4 and Figure 5In one of the embodiments, the point contact member 10a comprises at least three rolling components 10b, the three rolling components 10b are arranged along the circumference of the optical module 40, each of the rolling components 10b is connected with the optical module 40, and each of the rolling components 10b is accommodated at the lamp shell 20 and point-contactingly abuts against the inner wall of the lamp shell 20, the three rolling components 10b are independently rollably connected on the inner wall of the lamp shell 20 in any direction away from the side of the optical module 40, so that the optical module 40 can rotate relative to the lamp shell 20. Further, the at least three rolling components 10b are uniformly arranged along the circumference of the optical module 40. It can be understood that the three rolling components 10b are uniformly arranged along the circumference of the optical module 40, which realizes the stable accommodation of the optical module 40 on the inner wall of the lamp shell 20 through the point contact member 10a, and the three rolling components 10b are independently rollably connected on the inner wall of the lamp shell 20 in any direction away from the side of the optical module 40, that is, each of the rolling components 10b is rollably connected on the inner wall of the lamp shell 20 in any direction without the interference of the other rolling components 10b, for example, one of the rolling components 10b rolls a larger distance in the direction close to the light source module 30, while the other rolling components 10b roll a smaller distance in the direction close to the light source module 30, or one of the rolling components 10b does not roll on the shell, at this time, the optical module 40 as a whole rolls relative to the lamp shell 20 through the point contact member 10a, which promotes the rotation of the optical module 40 relative to the light source module 30, and realizes the adjustment of the irradiation angle of the irradiation angle adjustable lamp 10A; similarly, the different rolling components 10b roll in different directions and different distances, that is, the 360-degree adjustment of the irradiation angle of the irradiation angle adjustable lamp 10A is realized, in addition, each of the rolling components 10b is point-contactingly rollably connected on the inner wall of the lamp shell 20, which has smaller resistance relative to point-contactingly sliding, and further improves the smoothness of the adjustment of the irradiation angle of the irradiation angle adjustable lamp 10A.

[0069] Please refer to Figure 2 、 Figure 4 and Figure 5In one of the embodiments, the point contact member 10a comprises four rolling parts 10b, which are arranged along the circumference of the optical module 40, each of the rolling parts 10b is connected with the optical module 40, and each of the rolling parts 10b is accommodated at the lamp shell 20 and point-contactingly abuts against the inner wall of the lamp shell 20, the four rolling parts 10b independently rollably connect with the inner wall of the lamp shell 20 in any direction away from the side of the optical module 40, so that the optical module 40 can rotate relative to the lamp shell 20. Further, the four rolling parts are uniformly arranged along the circumference of the optical module 40. It can be understood that the number of the rolling parts 10b is at least three, when the number of the rolling parts 10b is three, the stable clamping of the optical module 40 on the inner wall of the lamp shell 20 can be achieved, and further, when the number of the rolling parts 10b is four, the user can better adjust the rotation of the optical module 40 on the inner wall of the lamp shell 20 through the rolling parts 10b, such as the effect of universal shaft, if the number of the rolling parts 10b is more than four, since the optical module 40 is rolled on the inner wall of the lamp shell 20 in a point-contacting manner through the rolling parts 10b, the smoothness of the movement of the optical module 40 on the lamp shell 20 is still high in the case that the number of the rolling parts 10b is more, and when the number of the rolling parts 10b is more, the contact points of the optical module 40 on the inner wall of the lamp shell 20 are more, the damping of the optical module 40 on the inner wall of the lamp shell 20 is stronger, and the user can more accurately realize the positioning adjustment of the optical module 40.

[0070] Please refer to Figures 7 to 9In one of the embodiments, each rolling component 10b comprises a bearing 100 and a spherical rolling member 200, the bearing 100 is used to connect with the optical module 40, the spherical rolling member 200 is rollably connected to the side of the bearing 100 away from the optical module 40, and the side of the spherical rolling member 200 away from the bearing 100 is used to point contact and abut with the inner wall of the lamp shell 20. The bearing 100 of each rolling component 10b is independently rollably connected to the inner wall of the lamp shell 20 along any direction through the spherical rolling member 200. Further, the spherical rolling member is a ball. It can be understood that the bearing 100 is arranged in the circumference of the optical module 40 and connected with the optical module 40, which better realizes the fixing effect of the rolling component 10b on the optical module 40. The spherical rolling member 200 is rollably connected to the side of the bearing 100 away from the optical module 40, and the side of the spherical rolling member 200 away from the bearing 100 is used to point contact and abut with the inner wall of the lamp shell 20. The bearing 100 of each rolling component 10b is independently rollably connected to the inner wall of the lamp shell 20 along any direction through the spherical rolling member 200, which better realizes the rolling connection of the bearing 100 to the inner wall of the lamp shell 20 through the spherical rolling member 200, further improves the rolling smoothness of the optical module 40 on the inner wall of the lamp shell 20, and further improves the adjustment smoothness of the illumination angle of the illumination angle adjustable lamp, and better realizes the rolling arrangement of the optical module 40 relative to the lamp shell 20 through the bearing 100 of each rolling component 10b, and further better realizes the 360-degree convenient adjustment of the illumination angle of the illumination angle adjustable lamp.

[0071] Please refer to Figures 7 to 9 In one of the embodiments, the side of the bearing 100 away from the optical module 40 is provided with a rolling groove 101, and the spherical rolling member 200 is clamped at the rolling groove 101 and rollably connected with the bearing 100, which improves the rolling connection stability of the spherical rolling member 200 on the bearing 100, further improves the rolling stability of the optical module 40 on the inner wall of the lamp shell 20 through the bearing 100, and further improves the stability of the 360-degree adjustment of the illumination angle of the illumination angle adjustable lamp.

[0072] Please refer to Figures 7 to 9In one of the embodiments, each rolling component 10b further comprises a telescopic component 300, one end of the telescopic component 300 is connected to the carrying component 100 near the optical module 40, the other end of the telescopic component 300 is connected to the optical module 40 near the carrying component 100, and the telescopic component 300 is configured to generate an elastic force to push the spherical rolling component 200 against the inner wall of the lamp shell 20. It can be understood that the telescopic component 300 is configured to generate an elastic force to push the spherical rolling component 200 to have a certain pressure to abut against the inner wall of the lamp shell 20, that is, the spherical rolling component 200 has the ability to adaptively adjust the contact pressure through the elastic force of the telescopic component 300, so that the spherical rolling component 200 is always in dynamic close contact with the inner wall of the lamp shell 20, compatible with the change of the distance between the inner wall of the lamp shell 20 and the assembly tolerance, effectively ensuring the effective abutment and accommodation of the optical module 40 on the inner wall of the lamp shell 20, that is, effectively realizing the effective point contact of the optical module 40 with the inner wall of the lamp shell 20 through the point contact component 10a, and further realizing the effective rolling arrangement of the optical module 40 on the inner wall of the lamp shell 20, ensuring the effective adjustment of the 360-degree illumination angle of the illumination angle adjustable lamp.

[0073] Please refer to Figure 3 and Figure 9 In one of the embodiments, the inner wall of the lamp shell 20 is provided with a cylindrical inner wall 2002, the point contact component 10a is in point contact with the cylindrical inner wall 2002, and the side of the point contact component 10a away from the optical module 40 is rollably connected to the cylindrical inner wall 2002 in any direction, so that the optical module 40 can rotate relative to the lamp shell 20. It can be understood that generally, if the optical module 40 is rollably arranged on the lamp shell 20, the overall peripheral wall of the optical module 40 needs to be spherical, and the inner wall of the lamp shell 20 is spherical, so that the optical module 40 can be effectively rolled on the inner wall of the lamp shell 20, but it can only realize the fixed distance between the optical module 40 and the light source module 30, that is, it limits the focal length of the illumination angle adjustable lamp, limits the use of the illumination angle adjustable lamp 10A in different scene arrangements, and cooperates with the point contact component 10a, that is, the telescopic component 300 generates an elastic force to realize that the spherical rolling component 200 is always in dynamic close contact with the inner wall of the lamp shell 20, realizes that the optical module 40 of the illumination angle adjustable lamp 10A can be effectively rolled on the cylindrical inner wall 2002, and further realizes that the focal length of the illumination angle adjustable lamp 10A can be changed, improves the universality of the illumination angle adjustable lamp 10A, and does not need to adjust the lamp shell 20 and the light source module 30, or increase auxiliary structures in the lamp shell 20 for realizing the relative rolling arrangement of the optical module 40, but directly realizes the relative rolling arrangement of the optical module 40 on the inner wall of the lamp shell 20 through the point contact component 10a, that is, it can be considered that the structural elements are reduced, but the relative rolling arrangement of the optical module 40 on the light source assembly can still be realized.

[0074] In one of the embodiments, the illumination angle adjusting structure comprises a plurality of point contact members, and the bearing members of the plurality of point contact members are linearly arranged in a direction intersecting the plane where the circumferential direction of the optical module is located. Further, the plurality of point contact members, the number of which ranges from two or more. It can be understood that the plurality of point contact members are arranged in the direction intersecting the plane where the circumferential direction of the optical module is located, which increases the abutment of the optical module with the inner wall of the lamp shell in the longitudinal dimension, thereby effectively improving the accommodation stability of the optical module on the inner wall of the lamp shell, effectively reducing the rolling angle control deviation of the optical module caused by the uneven stress during the relative rolling process, and improving the control accuracy of the 360-degree adjustment of the illumination angle of the illumination angle adjustable lamp.

[0075] Please refer to Figure 6 and Figure 9In one of the embodiments, the inner wall of the lamp shell 20 is provided with at least one annular spherical surface 2001, the point contact piece 10a is in point contact with the annular spherical surface 2001, and the side of the point contact piece 10a away from the optical module 40 is rollably connected to the annular spherical surface 2001 in any direction, so that the optical module 40 can rotate relative to the lamp shell 20. It can be understood that the inner wall of the lamp shell 20 is provided with at least one annular spherical surface 2001, so that when the optical module 40 is relatively rolled on the lamp shell 20 through the point contact piece 10a, the spherical rolling piece 200 is always in contact with the annular spherical surface 2001 through the extension piece 300, the rolling axis of the optical module 40 is unchanged, and the light emitting effect of the illumination angle adjustable lamp 10A can be better ensured. It can also be understood that the distance between the optical module 40 of the illumination angle adjustable lamp 10A and the light source module 30 changes, which will produce different lighting effects, specifically, the change of the illumination range and the beam shape, the closer the distance, the smaller the beam angle, and the smaller the illumination range; on the contrary, the farther the distance, the larger the beam angle, and the larger the illumination range. Therefore, in order to ensure the light emitting effect of the illumination angle adjustable lamp 10A and realize the adjustment of the focal length of the illumination angle adjustable lamp 10A, further, the inner wall of the lamp shell is provided with a plurality of annular spherical surfaces, the plurality of annular spherical surfaces are linearly arranged, the point contact piece is in point contact with any annular spherical surface, and the side of the point contact piece away from the optical module is rollably connected to any annular spherical surface in any direction, so that the optical module can rotate relative to the lamp shell. Further, the plurality of annular spherical surfaces, the number of which ranges from two or more annular spherical surfaces. It can be understood that due to the arrangement of the point contact piece, under the action of the elastic force of the extension piece, the optical module can be stably arranged on the annular spherical surface, and in the case that an external force acts on the optical module, the optical module can be rolled from one annular spherical surface to another annular spherical surface. In this way, the adjustment of the focal length of the lamp is realized when the optical module is arranged on different annular spherical surfaces, and the universality of the lamp is effectively improved.

[0076] In one of the embodiments, the inner wall of the lamp shell is provided with a damping protrusion, and the point contact piece is in point contact with the damping protrusion. Further, the damping protrusion is arranged on the annular spherical surface and the cylindrical side surface. Further, the damping protrusion is a grid-shaped protrusion. Further, the damping protrusion is a silica gel protrusion. Further, the spherical rolling piece of each rolling part of the point contact piece is in contact with the damping protrusion, which effectively improves the stability of the rolling positioning of the optical module on the inner wall of the lamp shell. Further, the damping protrusion is located on the annular spherical surface. Further, the damping protrusion is located on the inner wall of the cylinder.

[0077] In one of the embodiments, the spherical rolling member is sleeved with an auxiliary damping protrusion. Further, the auxiliary damping protrusion is a grid-shaped protrusion. Further, the auxiliary damping protrusion is a silica gel protrusion. Further, the auxiliary damping protrusion, together with the side surface of the spherical rolling member, encloses a rolling spherical surface, so as to better roll on the bearing member. The auxiliary damping protrusion cooperates with the damping protrusion to effectively realize the effective positioning and fixing of the spherical rolling member on the inner wall of the lamp shell. In particular, when the spherical rolling member is arranged to roll on the inner wall of the cylinder, the spherical rolling member is easily further slid from the inner wall of the lamp shell due to the elastic tension of the elastic member, and it is difficult to stably position and fix the spherical rolling member on the inner wall of the lamp shell. The auxiliary damping protrusion cooperates with the damping protrusion to effectively realize the effective positioning and fixing of the spherical rolling member on the inner wall of the cylinder, thereby realizing the stable positioning of the optical module relative to the light source module when the illumination angle adjusting structure is used in the lamp with adjustable illumination angle.

[0078] For reference, please also see Figures 10 to 11 In one of the embodiments, each rolling component 10b further comprises a guide member 400 connected to the peripheral wall of the optical module 40, and the side of the spherical rolling member 200 away from the bearing member 100 at least partially protrudes from the guide member 400. Further, the bearing member 100 is slidingly connected to the guide member 400, and the end of the elastic member 300 close to the optical module 40 is connected to the optical module 40 through the guide member 400, and the guide member 400 is configured to allow the elastic member 300 to be retracted, so that the spherical rolling member 200 can slide relative to the guide member 400 in the direction close to or away from the optical module 40. It can be understood that the elastic member 300 is a structure that can generate elastic force, such as a metal elastic member and a polymer elastic member, especially a spring. During rolling, it is easy to bend and deflect, which greatly affects the relative rolling stability of the optical module 40 on the inner wall of the lamp shell 20. Therefore, the bearing member 100 is slidingly connected to the guide member 400, and the elastic member 300 is retracted in the guide member 400, so that the guide member 400 limits the elastic member 300 to reduce the bending and deflection of the elastic member 300, thereby improving the relative rolling stability of the optical module 40 on the inner wall of the lamp shell 20.

[0079] For reference, please also see Figures 10 to 11 In one of the embodiments, the guide member 400 of each rolling component 10b is provided with a sliding groove 401 with the same extension direction as the length direction of the elastic member 300, the elastic member 300 is accommodated in the sliding groove 401, and the bearing member 100 is at least partially clamped at the sliding groove 401 and slidingly connected with the groove wall of the sliding groove 401, the two ends of the elastic member 300 abut against the groove bottom of the sliding groove 401 and the side of the bearing member 100 close to the optical module 40, respectively, thereby stably and elastically retracting the elastic member 300 in the guide member 400.

[0080] Reference is also made to Figures 10 to 11In one of the embodiments, the guide 400 of each rolling component 10b comprises a mounting seat 410 connected to the peripheral wall of the optical module 40 and a telescopic sliding part 420 sleeved on the mounting seat 410 and slidingly connected with the mounting seat 410, the sliding direction of the mounting seat 410 is the same as the length direction of the telescopic part 300, the telescopic sliding part 420 at least partially protrudes from the side of the mounting seat 410 away from the optical module 40, and the spherical rolling part 200 at least partially protrudes from the telescopic sliding part 420. Further, one end of the telescopic part 300 close to the optical module 40 is connected to the optical module 40 through the mounting seat 410, and the mounting seat 410 and the telescopic sliding part 420 are both configured to allow the telescopic part 300 to be telescopically arranged. Further, when the telescopic part 300 is telescopically arranged in the mounting seat 410, the bearing 100 is slidingly connected to the mounting seat 410; when the telescopic part 300 is telescopically arranged in the mounting seat 410 and the telescopic sliding part 420, the bearing 100 slides away from the mounting seat 410, and the bearing 100 is clamped on the telescopic sliding part 420 and further pushes the telescopic sliding part 420 to slide away from the optical module 40. It can be understood that, due to the limited space in the lamp shell 20, in order to better improve the light output effect of the adjustable illumination angle lamp, the optical module 40 needs to completely block the light outlet of the lamp shell 20, but in order to better adapt to the use of the optical module 40 on the inner wall of the cylinder, the telescopic amount of the point contact 10a needs to be larger, so that when the optical module 40 rolls relative to the lamp shell 20 at a larger angle, the point contact 10a can effectively abut on the inner wall of the lamp shell 20, and the telescopic amount of the point contact 10a depends on the telescopic range of the telescopic part 300, that is, the length of the guide 400, but the length of the guide 400 is longer, which will affect the light output effect of the adjustable illumination angle lamp, therefore, in order for the adjustable illumination angle lamp to be compatible with better light output effect and suitable for rolling abutment stability when the optical module 40 rolls relative to the lamp shell 20 at a larger angle, the telescopic sliding part 420 is sleeved on the mounting seat 410 and slidingly connected with the mounting seat 410, the sliding direction of the mounting seat 410 is the same as the length direction of the telescopic part 300, that is, the guide 400 is also provided as a telescopic structure, and the bearing 100 is driven to slide by the telescopic sliding part 420, which better realizes the improvement of the telescopic range of the telescopic part 300 with smaller space, and further realizes the improvement of the relative rolling abutment stability of the optical module 40 on the inner wall of the lamp shell 20 on the basis of allowing the optical module 40 to block more light outlets of the lamp shell 20, that is, on the basis of ensuring the light output effect of the adjustable illumination angle lamp. Further, the sliding grooves 401 are respectively located on the mounting seat 410 and the telescopic sliding part 420, and the depth of the sliding grooves 401 changes through the mutual sliding of the mounting seat 410 and the telescopic sliding part 420.

[0081] Please refer to Figures 10 to 11 In one embodiment, a first stopper 430 is formed on the outer wall of the mounting portion 410, and the first stopper 430 is located on the side of the mounting portion 410 away from the optical module 40. Further, a second stopper 440 is formed on the inner wall of the telescopic sliding portion 420, and the second stopper 440 is located on the side of the telescopic sliding portion 420 close to the optical module 40. Further, when the telescopic member 300 is arranged in the mounting portion 410 and the telescopic sliding portion 420, the carrier 100 pushes the telescopic sliding portion 420 to slide away from the optical module 40 until the side of the first stopper 430 close to the optical module 40 abuts against the side of the second stopper 440 away from the optical module 40, thereby avoiding the telescopic sliding portion 420 from sliding out of the mounting portion 410.

[0082] Please refer to Figures 10 to 11 In one embodiment, a third stopper 500 is formed on the outer wall of the carrier 100, and the third stopper 500 is located on the side of the carrier 100 close to the optical module 40. Further, a fourth stopper 450 is formed on the inner wall of the telescopic sliding portion 420, and the fourth stopper 450 is located on the side of the telescopic sliding portion 420 away from the optical module 40. Further, when the telescopic member 300 is arranged in the mounting portion 410 and the telescopic sliding portion 420, the side of the third stopper 500 away from the optical module 40 abuts against the side of the fourth stopper close to the optical module 40, thereby better ensuring that the carrier 100 can better drive the telescopic sliding portion 420 to slide away from the optical module 40 when the carrier 100 slides away from the optical module 40.

[0083] In one of the embodiments, the elastic force generated by the elastic member of at least one rolling component is different from the elastic force generated by the elastic member of the rest of the rolling components. Further, the inner wall of the lamp housing is provided with a cylindrical inner wall, the spherical rolling component is in point contact with the cylindrical inner wall, and the side of the spherical rolling component away from the bearing member is rollably connected to the cylindrical inner wall in any direction, so that the optical module can rotate relative to the lamp housing. It can be understood that when the optical module can roll relative to the lamp housing through the point contact component, if the inner wall of the lamp housing is a cylindrical inner wall, and the elastic force generated by the elastic member is the same, the position of the axis of the optical module will change when rolling, that is, the forming position of the light spot of the lamp and the light emission effect will be affected. Therefore, the elastic force generated by the elastic member of at least one rolling component is different from the elastic force generated by the elastic member of the rest of the rolling components. The adjustment of the number of elastic forces of the elastic members of the specific rolling components and the adjustment of the difference value of the elastic forces need to be adjusted according to the optical design of the light emission port width of the lamp housing and the type of the optical module. Here, it is not discussed, but the elastic force generated by the elastic member of at least one rolling component is different from the elastic force generated by the elastic member of the rest of the rolling components, which can realize the position of the axis of the optical module during rolling relative to the lamp housing, and further better ensure the light emission effect of the lamp.

[0084] In one of the embodiments, the optical module includes a lens. Further, the optical module is a TIR lens. Further, the lens is connected with the point contact component through a lens mounting frame. Further, the lens mounting frame is connected with the elastic member. Further, the lens mounting frame is connected with the guide member. Further, the lens mounting frame is connected with the mounting seat part.
