Description

Technical Field

[0001] The present invention relates to the technical field of lamps, and in particular to an illumination angle adjustment structure and a lamp with adjustable illumination angle. Background Art

[0002] Angle-adjustable lamps refer to lamps that are designed to allow users to adjust the illumination angle according to their needs. This design enables the lamps to adapt to different lighting needs of users, improves flexibility and comfort of use. With the continuous updating of lamp design, universal adjustable lamps have been born. Universal adjustable lamps can adjust the illumination angle of the lamps 360 degrees, better improving the flexibility of use. For example, the invention patent application with application number CN202310312501.2 allows the light-transmitting member to rotate relative to the mounting member, and the mounting member rotates relative to the lamp housing, limiting the rotation direction of the light-transmitting member driven by the rotating mounting member to be different from the rotation direction of the rotating light-transmitting member itself. In this way, the light-transmitting member can rotate independently in two directions, better realize the 360-degree rotation of the optical lens, and further deflect the light emitted by the light source through the optical lens, so as to realize the 360-degree adjustment of the illumination angle of the lamp. However, it still has the following problems:

[0003] 1. The 360-degree adjustment of the lighting angle of the lamp needs to be achieved by rotating in two directions, which is not convenient for adjustment;

[0057] The present application provides a lamp with adjustable illumination angle. The illumination angle adjustment structure in the above-mentioned lamp with adjustable illumination angle is used to assemble the optical module on the lamp housing so that the light emitted by the light source module is incident on the optical module. Furthermore, the optical module is arranged to avoid the lamp housing and the light source module respectively.

[0058] In order to better understand the lighting fixture with adjustable illumination angle of the present application, the illumination angle adjustment structure is further explained below:

[0059] Please also read Figures 1 to 3 , an irradiation angle adjustment structure 10 of one embodiment includes a point contact 10a. Fig.12 The point contact 10a is wound around the peripheral wall of the optical module 40 and connected to the optical module 40. The point contact 10a and the optical module 40 are accommodated in the lamp housing 20 together. The point contact 10a is in point contact with the inner wall of the lamp housing 20, and the side of the point contact 10a away from the optical module 40 can be rolled and connected to the inner wall of the lamp housing 20 in any direction, so that the optical module 40 can be rotated relative to the lamp housing 20 to change the light output direction when the light is emitted through the optical module 40.

[0060] The above-mentioned illumination angle adjustment structure 10 enables the point contact member 10a to be wound around the peripheral wall of the optical module 40 and connected to the optical module 40, that is, the optical module 40 is connected to the lamp housing 20 through the point contact member 10a, and the point contact member 10a is in point contact with the inner wall of the lamp housing 20, that is, the indirect point contact abutment of the optical module 40 on the lamp housing 20 is realized, and the side of the point contact member 10a away from the optical module 40 can be rolled on the inner wall of the lamp housing 20 in any direction, so that the point contact member 10a drives the optical module 40 to roll relative to the inner wall of the lamp housing 20, thereby causing the optical module 40 to roll at any direction. The optical module 40 can rotate relative to the light source module 30 in the same direction, thereby realizing a 360-degree point-contact rotation of the optical module 40 relative to the light source module, and deflecting the light emitted by the light source module 30 through the optical module 40, thereby realizing an improvement in the smoothness of the 360-degree adjustment of the illumination angle of the lamp 10A with adjustable illumination angle. Moreover, the user can complete the 360-degree adjustment of the illumination angle of the lamp 10A with adjustable illumination angle 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 housing 20, thereby greatly improving the convenience of adjusting the illumination angle of the lamp 10A with adjustable illumination angle.

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

[0062] In order to better understand the lamp with adjustable illumination angle of the present application, the lamp with adjustable illumination angle of the present application is further explained below in combination with the illumination angle adjustment structure:

[0063] Please also read Figures 1 to 3 , a lamp 10A with adjustable illumination angle in one embodiment includes a lamp housing 20, a light source module 30, an optical module 40 and an illumination angle adjustment structure 10 of any of the above embodiments. The light source module 30 is disposed in the lamp housing 20. The point contact 10a is wound around the peripheral wall of the optical module 40 and connected to the optical module 40, and the point contact 10a and the optical module 40 are accommodated in the lamp housing 20 together, so that the light emitted by the light source module 30 is emitted into the optical module 40. The point contact 10a is in point contact with the inner wall of the lamp housing 20, and the side of the point contact 10a away from the optical module 40 can be rolled and connected to the inner wall of the lamp housing 20 in any direction, so that the optical module 40 can be rotated relative to the lamp housing 20 to change the light emission direction when the light is emitted through the optical module 40.

[0064] The above-mentioned lamp 10A with adjustable illumination angle adopts the illumination angle adjustment structure 10, which better realizes the convenience and smoothness of adjusting the illumination angle of the lamp 10A with adjustable illumination angle.

[0065] It should be noted that the side of the point contact away from the optical module can be rolled and connected to the inner wall of the lamp housing in any direction. It can be understood that: the side of the point contact used to abut against the inner wall of the lamp housing is a spherical surface to allow the point contact as a whole to roll in any direction relative to the inner wall of the lamp housing, and the point contact is arranged around the peripheral wall of the optical module, so that the point contact drives the optical module to roll relative to the inner wall of the lamp housing and prompts the optical module to rotate relative to the light source module in any direction, that is, the optical module is rotated 360 degrees relative to the light source module, and the light emitted by the light source module is deflected by the optical module, thereby realizing a 360-degree adjustment of the illumination angle of the lamp.

[0066] It should also be noted that, since the point contact piece enables the optical module to rotate relative to the light source module in any direction, when the user applies force to the optical module and forces the point contact piece to roll relative to the inner wall of the lamp housing, the illumination angle of the lamp can be quickly adjusted 360 degrees, which effectively improves the convenience of adjusting the illumination angle of the lamp. In addition, since the point contact piece and the inner wall of the lamp housing are in point contact and rolling, the smoothness of adjusting the illumination angle of the lamp is better achieved.

[0067] It should be noted that since the optical module is restricted in the lamp housing by the point contact and rotates relative to the light source module, that is, the rotation restriction of the optical module is carried out in the lamp housing, the user can better control the relative setting of the light incident surface of the optical module and the light source module on the basis of adjusting the rotation angle of the optical module, so as to effectively realize the light emitted by the light source module to be incident on the light incident surface of the optical module, and the light is further emitted through the light emitting surface of the optical module, thereby realizing effective control of the light emitting effect of the lamp with adjustable illumination angle. That is to say, when the optical module is rollingly set on the inner wall of the lamp housing through the point contact, 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 realizing effective adjustment of the illumination angle of the lamp with adjustable illumination angle.

[0068] Please also read Figure 2 , Figure 4 and Figure 5In one embodiment, the point contact member 10a includes at least three rolling components 10b, which are arranged along the circumference of the optical module 40, each rolling component 10b is connected to the optical module 40, and each rolling component 10b is accommodated in the lamp housing 20 and point-contacts with the inner wall of the lamp housing 20. The sides of the three rolling components 10b away from the optical module 40 can be independently connected to the inner wall of the lamp housing 20 in a rolling manner in any direction, so that the optical module 40 can rotate relative to the lamp housing 20. Further, at least three rolling components 10b are evenly arranged in the circumference of the optical module 40. It can be understood that the three rolling components 10b are evenly arranged along the circumference of the optical module 40, so that the optical module 40 is stably accommodated on the inner wall of the lamp housing 20 through the point contact 10a, and the three rolling components 10b are independently rollably connected to the inner wall of the lamp housing 20 in any direction away from the optical module 40, that is, each rolling component 10b is not interfered by the other rolling components 10b and can be rollably connected to the inner wall of the lamp housing 20 in any direction, such as 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 rolls a smaller distance in the housing. No rolling occurs on the body. At this time, the optical module 40 rolls as a whole relative to the lamp housing 20 through the point contact piece 10a, which causes the optical module 40 to rotate relative to the light source module 30, thereby realizing the adjustment of the illumination angle of the lamp 10A with adjustable illumination angle; similarly, different rolling components 10b are caused to roll in different directions and at different distances, thereby realizing 360-degree adjustment of the illumination angle of the lamp 10A with adjustable illumination angle. In addition, each rolling component 10b is point-contact rollingly connected to the inner wall of the lamp housing 20, which has smaller resistance than point-contact sliding, thereby further improving the smoothness of the illumination angle adjustment of the lamp 10A with adjustable illumination angle.

[0069] Please also read Figure 2 , Figure 4 and Figure 5In one embodiment, the point contact member 10a includes four rolling parts 10b, which are arranged along the circumference of the optical module 40, each rolling part 10b is connected to the optical module 40, and each rolling part 10b is accommodated in the lamp housing 20 and point-contacts with the inner wall of the lamp housing 20. The side of the four rolling parts 10b away from the optical module 40 can be independently connected to the inner wall of the lamp housing 20 in any direction, so that the optical module 40 can rotate relative to the lamp housing 20. Further, the four rolling parts are evenly arranged in the circumference of the optical module 40. It can be understood that the number of rolling components 10b is at least three. When the number of rolling components 10b is three, the optical module 40 can be stably connected to the inner wall of the lamp housing 20. If the number of rolling components 10b is further four, the user can better adjust the rotation of the optical module 40 on the inner wall of the lamp housing 20 through the rolling components 10b, such as the effect of a universal joint. If the number of rolling components 10b is greater than four, since the optical module 40 rolls in a point contact manner with the inner wall of the lamp housing 20 through the rolling components 10b, when the number of rolling components 10b is large, the movement smoothness of the optical module 40 on the lamp housing 20 is still high. When the number of rolling components 10b is large, the optical module 40 has more contact points with the inner wall of the lamp housing 20, and the damping of the optical module 40 on the inner wall of the lamp housing 20 is stronger, so that the user can more accurately realize the positioning adjustment of the optical module 40.

[0070] Please also read Figures 7 to 9In one embodiment, each rolling component 10b includes a carrier 100 and a spherical rolling component 200, the carrier 100 is used to connect with the optical module 40, the spherical rolling component 200 can be rollably connected to the side of the carrier 100 away from the optical module 40, and the side of the spherical rolling component 200 away from the carrier 100 is used to point-contact with the inner wall of the lamp housing 20, and the carrier 100 of each rolling component 10b is independently rollably connected to the inner wall of the lamp housing 20 through the spherical rolling component 200 in any direction. Further, the spherical rolling component is a ball. It can be understood that the carrier 100 is arranged in the circumference of the optical module 40 and connected to the optical module 40, so that the rolling component 10b can better achieve the fixing effect of the optical module 40, and the spherical rolling component 200 can be roll-connected to the side of the carrier 100 away from the optical module 40, and the side of the spherical rolling component 200 away from the carrier 100 is used for point contact with the inner wall of the lamp housing 20, and the carrier 100 with each rolling component 10b is independently connected to the lamp housing 20 by rolling in any direction through the spherical rolling component 200. 0, that is, the supporting member 100 is better connected to the inner wall of the lamp housing 20 by rolling through the spherical rolling member 200, further improving the rolling smoothness of the optical module 40 on the inner wall of the lamp housing 20, thereby further improving the adjustment smoothness of the illumination angle of the lamp with adjustable illumination angle, and better realizing that the optical module 40 can be rolled relative to the lamp housing 20 through the supporting member 100 of each rolling component 10b, thereby better realizing the convenient 360-degree adjustment of the illumination angle of the lamp with adjustable illumination angle.

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

[0072] Please also read Figures 7 to 9In one embodiment, each rolling component 10b also includes a telescopic member 300, one end of the telescopic member 300 is connected to a side of the carrier 100 close to the optical module 40, and the other end of the telescopic member 300 is connected to a side of the optical module 40 close to the carrier 100, and the telescopic member 300 is configured to generate an elastic force to push the spherical rolling member 200 to press against the inner wall of the lamp housing 20. It can be understood that the telescopic member 300 is configured to generate an elastic force for pushing the spherical rolling member 200 to abut against the inner wall of the lamp housing 20 with a certain pressure, that is, the spherical rolling member 200 has the ability to adaptively adjust the contact pressure through the elastic force of the telescopic member 300 and always maintains dynamic close contact with the inner wall of the lamp housing 20, and is compatible with the changes in the distance between the inner wall of the lamp housing 20 and the assembly tolerance, effectively ensuring the effective abutment and accommodation of the optical module 40 on the inner wall of the lamp housing 20, that is, effectively realizing the effective point contact of the optical module 40 at various locations of the inner wall of the lamp housing 20 through the point contact member 10a, thereby realizing the effective rolling setting of the optical module 40 at various locations of the inner wall of the lamp housing 20, ensuring the effective adjustment of the illumination angle of the lamp with adjustable illumination angle by 360 degrees.

[0073] Please also read Figure 3 and Fig. 9 In one embodiment, a cylindrical inner wall 2002 is provided on the inner wall of the lamp housing 20, and the point contact member 10a is in point contact with the cylindrical inner wall 2002, and the side of the point contact member 10a away from the optical module 40 can be rolled and connected to the cylindrical inner wall 2002 in any direction, so that the optical module 40 can rotate relative to the lamp housing 20. It can be understood that, generally, if the optical module 40 is to be rollably arranged on the lamp housing 20, it is necessary to make the entire peripheral wall of the optical module 40 present a spherical surface, and the inner wall of the lamp housing 20 is a spherical surface, so that the optical module 40 can effectively roll on the inner wall of the lamp housing 20. However, it can only achieve a fixed distance between the optical module 40 and the light source module 30, that is, it limits the focal length of the lamp with adjustable illumination angle, and limits the use of the lamp with adjustable illumination angle 10A in different scene arrangements. In combination with the point contact member 10a, the telescopic member 300 generates elastic force to achieve dynamic and close contact between the spherical rolling member 200 and the inner wall of the lamp housing 20 at all times. The optical module 40 of the lamp 10A with adjustable illumination angle can be effectively rolled on the inner wall 2002 of the cylinder, thereby realizing the variable focal length of the lamp 10A with adjustable illumination angle, improving the universality of the lamp 10A with adjustable illumination angle, and there is no need to adjust the lamp housing 20 and the light source module 30, or to add an auxiliary structure in the lamp housing 20 to realize the relative rolling setting of the optical module 40. Instead, the relative rolling setting of the optical module 40 on the inner wall of the lamp housing 20 is directly realized through the point contact 10a. In other words, it can be considered that the structural elements are reduced, but the relative rolling setting of the optical module 40 on the light source assembly can still be realized.

[0074] In one of the embodiments, the illumination angle adjustment structure includes a plurality of point contacts, and the carriers of the plurality of point contacts are linearly arranged along a direction intersecting with a plane where the circumference of the optical module is located. Further, the plurality of point contacts has a quantity range of: two or more point contacts. It can be understood that a plurality of point contacts are arranged in a direction intersecting with a plane where the circumference of the optical module is located, thereby increasing the contact between the optical module and the inner wall of the lamp housing in the longitudinal dimension, thereby effectively improving the accommodation stability of the optical module on the inner wall of the lamp housing, effectively reducing the rolling angle control deviation of the optical module caused by uneven force during the relative rolling of the optical module, and improving the control accuracy of the 360-degree adjustment of the illumination angle of the lamp with adjustable illumination angle.

[0075] See also Figure 6 and Fig. 9In one embodiment, at least one annular spherical surface 2001 is provided on the inner wall of the lamp housing 20, and the point contact member 10a is in point contact with the annular spherical surface 2001, and the side of the point contact member 10a away from the optical module 40 can be rolled and connected to the annular spherical surface 2001 in any direction, so that the optical module 40 can rotate relative to the lamp housing 20. It can be understood that when at least one annular spherical surface 2001 is provided on the inner wall of the lamp housing 20, when the optical module 40 can roll relatively on the lamp housing 20 through the point contact member 10a, the spherical rolling member 200 is always in contact with the annular spherical surface 2001 through the telescopic member 300, and the rolling axis of the optical module 40 remains unchanged, which can better ensure the light output effect of the lamp 10A with adjustable illumination angle. It can also be understood that different lighting effects will be produced when the distance between the optical module 40 and the light source module 30 of the lamp 10A with adjustable illumination angle changes, which is specifically manifested in the change of the illumination range and the shape of the light beam. The closer the distance, the smaller the beam angle and the smaller the illumination range; conversely, the farther the distance, the larger the beam angle and the larger the illumination range. Therefore, in order to achieve the adjustable focal length of the lamp 10A with adjustable illumination angle on the basis of ensuring the light emitting effect of the lamp 10A with adjustable illumination angle, further, a plurality of annular spherical surfaces are provided on the inner wall of the lamp housing, and the plurality of annular spherical surfaces are linearly arranged, and 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 can be rolled and connected to any annular spherical surface in any direction, so that the optical module can rotate relative to the lamp housing. Further, the plurality of annular spherical surfaces, the number range is: two or more annular spherical surfaces. It can be understood that due to the setting of the point contact piece, under the action of the elastic force of the telescopic piece, the optical module can be better stably set on the annular spherical surface, and when an external force acts on the optical module, the optical module can be better rolled from one annular spherical surface to another annular spherical surface. In this way, when the optical module is rolled on different annular spherical surfaces, the focal length of the lamp can be adjusted, which effectively improves the universality of the lamp.

[0076] In one embodiment, a damping protrusion is laid on the inner wall of the lamp housing, and the point contact piece contacts and abuts against the damping protrusion point. Further, the damping protrusion is laid on the annular spherical surface and the round side surface. Further, the damping protrusion is a grid-shaped protrusion. Further, the damping protrusion is a silicone protrusion. Further, the spherical rolling element of each rolling component of the point contact piece abuts against the damping protrusion, which effectively improves the rolling positioning and limiting stability of the optical module on the inner wall of the lamp housing. 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, an auxiliary damping protrusion is sleeved on the spherical rolling member. Further, the auxiliary damping protrusion is a grid-shaped protrusion. Further, the auxiliary damping protrusion is a silicone protrusion. Further, the auxiliary damping protrusion and a side surface away from the spherical rolling member together form a rolling spherical surface, so as to roll smoothly on the bearing member better, and the auxiliary damping protrusion cooperates with the damping protrusion to effectively realize the effective positioning and fixation of the spherical rolling member on the inner wall of the lamp housing. In particular, when the spherical rolling member is rolled and set on the inner wall of the cylinder, the spherical rolling member is easily further slid from the inner wall of the lamp housing due to the elastic tension of the telescopic member, making it difficult for the spherical rolling member to be stably limited and fixed on the inner wall of the lamp housing, and the auxiliary damping protrusion cooperates with the damping protrusion to effectively realize the effective positioning and fixation of the spherical rolling member on the inner wall of the cylinder, thereby realizing the stable rotation positioning of the optical module relative to the light source module when the illumination angle adjustment structure is used in a lamp with adjustable illumination angle.

[0078] Please also read Figure 10 to Figure 11 In one embodiment, each rolling component 10b further includes a guide member 400, which is connected to the peripheral wall of the optical module 40, and the side of the spherical rolling member 200 away from the supporting member 100 at least partially protrudes from the guide member 400. Further, the supporting member 100 is slidably connected to the guide member 400, and the end of the telescopic 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 telescopic member 300 to be telescoped inside, so that the spherical rolling member 200 can slide relative to the guide member 400 in a direction close to or away from the optical module 40. It can be understood that the telescopic member 300 is a structure that can generate elastic force, such as a metal elastic member and a polymer elastic member, especially a spring, and it is easy to bend and deflect during the rolling process, which will greatly affect the relative rolling stability of the optical module 40 on the inner wall of the lamp housing 20. Therefore, the supporting member 100 is slidably connected to the guide member 400, and the telescopic member 300 is telescoped in the guide member 400, so that the guide member 400 restricts the telescopic member 300 to reduce the bending and deflection of the telescopic member 300. In this way, the relative rolling stability of the optical module 40 on the inner wall of the lamp housing 20 is improved.

[0079] Please also read Figure 10 to Figure 11 In one embodiment, the guide member 400 of each rolling component 10b is provided with a sliding groove 401 extending in the same direction as the length direction of the telescopic member 300, the telescopic member 300 is accommodated in the sliding groove 401, and the supporting member 100 is at least partially engaged in the sliding groove 401 and slidably connected to the groove wall of the sliding groove 401, and the two ends of the telescopic member 300 are respectively abutted against the bottom of the sliding groove 401 and the side of the supporting member 100 close to the optical module 40, thereby better realizing the stable elastic expansion and contraction of the telescopic member 300 on the guide member 400.

[0080] Please also read Figure 10 to Figure 11In one embodiment, the guide member 400 of each rolling component 10b includes a mounting seat portion 410 and a telescopic sliding portion 420, the mounting seat portion 410 is connected to the peripheral wall of the optical module 40, the telescopic sliding portion 420 is sleeved on the mounting seat portion 410 and slidably connected with the mounting seat portion 410, the sliding direction of the mounting seat portion 410 is the same as the length direction of the telescopic member 300, the telescopic sliding portion 420 at least partially protrudes from the side of the mounting seat portion 410 away from the optical module 40, and the spherical rolling member 200 at least partially protrudes from the telescopic sliding portion 420. Further, one end of the telescopic member 300 close to the optical module 40 is connected to the optical module 40 through the mounting seat portion 410, and the mounting seat portion 410 and the telescopic sliding portion 420 are both configured to allow the telescopic member 300 to telescope inside. Furthermore, when the telescopic member 300 is telescopically disposed on the mounting seat portion 410, the supporting member 100 is slidably connected to the mounting seat portion 410; when the telescopic member 300 is telescopically disposed on the mounting seat portion 410 and the telescopic sliding portion 420, the supporting member 100 slides away from the mounting seat portion 410, and the supporting member 100 is stuck on the telescopic sliding portion 420 and further pushes the telescopic sliding portion 420 to slide in a direction away from the optical module 40. It can be understood that due to the limited space in the lamp housing 20, in order to better improve the light-emitting effect of the lamp with adjustable illumination angle, the optical module 40 needs to more completely cover the light outlet of the lamp housing 20. However, in order to better adapt 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. In this way, when the optical module 40 rolls at a larger angle relative to the lamp housing 20, the point contact 10a can effectively abut against the inner wall of the lamp housing 20. The telescopic amount of the point contact 10a depends on the telescopic range of the telescopic member 300, that is, the length of the guide member 400. However, a longer length of the guide member 400 will affect the light-emitting effect of the lamp with adjustable illumination angle. Therefore, in order for the lamp with adjustable illumination angle to be compatible with better light-emitting effect and adaptability, The rolling abutment stability when the optical module 40 rolls at a large angle relative to the lamp housing 20 is achieved, so that the telescopic sliding part 420 is sleeved on the mounting seat part 410 and is slidably connected with the mounting seat part 410, and the sliding direction of the mounting seat part 410 is the same as the length direction of the telescopic member 300, that is, the guide member 400 is also set as a telescopic structure, and the bearing member 100 is driven to slide by the telescopic sliding part 420, so that the telescopic range of the telescopic member 300 is improved by using a smaller space, and then on the basis of allowing the optical module 40 to block more of the light outlet of the lamp housing 20, that is, on the basis of ensuring the light emitting effect of the lamp with adjustable illumination angle, the relative rolling abutment stability of the optical module 40 on the inner wall of the lamp housing 20 is improved. Further, the sliding groove 401 is respectively located on the mounting seat part 410 and the telescopic sliding part 420, and the depth of the sliding groove 401 changes by the mutual sliding of the mounting seat part 410 and the telescopic sliding part 420.

[0081] Please also read Figure 10 to Figure 11 In one embodiment, a first stopper 430 is convexly provided on the outer wall of the mounting seat 410, and the first stopper 430 is located on the side of the mounting seat 410 away from the optical module 40. Further, a second stopper 440 is convexly provided 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 telescopically arranged on the mounting seat 410 and the telescopic sliding portion 420, the carrier 100 pushes the telescopic sliding portion 420 to slide in a direction 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 preventing the telescopic sliding portion 420 from sliding off the mounting seat 410.

[0082] Please also read Figure 10 to Figure 11 In one embodiment, a third stopper 500 is convexly provided 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 convexly provided on the inner wall of the telescopic sliding part 420, and the fourth stopper 450 is located on the side of the telescopic sliding part 420 away from the optical module 40. Further, when the telescopic member 300 is telescopically arranged on the mounting seat part 410 and the telescopic sliding part 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, which better ensures that when the carrier 100 slides in the direction away from the optical module 40, the telescopic sliding part 420 can be driven to slide in the direction away from the optical module 40.

[0083] In one embodiment, the elastic force generated by the telescopic part of at least one rolling component is different from the elastic force generated by the telescopic parts of the other rolling components. Furthermore, a cylindrical inner wall is provided on the inner wall of the lamp housing, 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 component can be rolled and 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 piece, if the inner wall of the lamp housing is a cylindrical inner wall, when the elastic force generated by the telescopic parts is the same, the position of the axis of the optical module will change when it rolls, which will affect the formation position of the light spot of the lamp and the light emission effect. Therefore, the elastic force generated by the telescopic part of at least one rolling component is different from the elastic force generated by the telescopic parts of the remaining rolling components. The adjustment of the number of different elastic forces of the telescopic parts of the specific rolling parts and the adjustment of the elastic force difference value need to be adjusted according to the optical design width of the light outlet of the lamp housing and the type of optical module, which will not be discussed here. However, by making the elastic force generated by the telescopic part of at least one rolling component different from the elastic force generated by the telescopic parts of the remaining rolling components, the position of the axis of the optical module can be achieved during the rolling process relative to the lamp housing, thereby better ensuring the light emission effect of the lamp.

[0084] In one embodiment, the optical module includes a lens. Further, the optical module is a TIR lens. Further, the lens is connected to the point contact member through a lens mounting frame. Further, the lens mounting frame is connected to the telescopic member. Further, the lens mounting frame is connected to the guide member. Further, the lens mounting frame is connected to the mounting seat.

[0085] In one embodiment, the light source module includes an LED lamp.

[0086] Compared with the prior art, the present invention has at least the following advantages:

[0087] The illumination angle adjustment structure 10 of the present invention enables the point contact member 10a to be wound around the peripheral wall of the optical module 40 and connected to the optical module 40, that is, the optical module 40 is connected to the lamp housing 20 through the point contact member 10a, and the point contact member 10a is in point contact with the inner wall of the lamp housing 20, that is, the indirect point contact and abutment of the optical module 40 to the lamp housing 20 is realized, and the side of the point contact member 10a away from the optical module 40 can be rolled and connected to the inner wall of the lamp housing 20 in any direction, so that the point contact member 10a drives the optical module 40 to roll relative to the inner wall of the lamp housing 20, thereby causing the optical module 40 to roll at any direction. The optical module 40 can be rotated in an intended direction relative to the light source module 30, thereby realizing a 360-degree point-contact rotation of the optical module 40 relative to the light source module, and the light emitted by the light source module 30 is deflected by the optical module 40, thereby realizing an improvement in the smoothness of the 360-degree adjustment of the illumination angle of the lamp 10A with adjustable illumination angle. The user can complete the 360-degree adjustment of the illumination angle of the lamp 10A with adjustable illumination angle 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 housing 20, thereby greatly improving the convenience of adjusting the illumination angle of the lamp 10A with adjustable illumination angle.

[0088] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
