Description

Technical Field

[0001] This utility model patent relates to the technical field of zoom lamps, specifically to a rotatable zoom lens module and a stepless zoom lens module. Background Technology

[0002] Different lighting locations have different requirements for the light distribution of luminaires. In particular, in commercial lighting and exhibition hall lighting, where there are high requirements for lighting effects such as light spot, light color, and illuminance, the requirements for the projection range and projection angle of luminaires are even better.

[0003] Therefore, using a lamp with focusing capability is more in line with lighting needs. For example, the prior patent with authorization announcement number CN208457873U discloses a lamp with adjustable focus, including a lamp body and: an adjusting sleeve disposed on the lamp body, the adjusting sleeve having an active unit; a retaining ring disposed between the adjusting sleeve and the lamp body to prevent the adjusting sleeve from moving in the axial direction; an end cap disposed at the outer end of the adjusting sleeve; and a movable seat located inside the adjusting sleeve and within the space defined by the retaining ring and the end cap for mounting a lens unit, the movable seat having a driven unit at a corresponding position to the active unit; the active unit and the driven unit are connected by a spiral structure so that when the adjusting sleeve is rotated, a spiral relative displacement occurs between the active unit and the driven unit, and the movable seat moves forward or backward axially relative to the adjusting sleeve.

[0004] In the existing technology, the lamps only have fine adjustment, which results in poor focusing effect. At the same time, they do not have the ability to adjust the projection angle, which cannot meet the projection of multiple light output directions and the various usage needs of the lamps, and also affects the focusing effect of the lamps. Utility Model Content

[0012] Furthermore, the fixing component includes a fixing plate and a linkage plate. The fixing plate and the linkage plate are sleeved and movably arranged. The fixing plate is assembled with the light shield. The linkage plate is docked with the other end of the adjusting column. The linkage plate is linked with the rotating component. The fixing plate has a fixing tooth set, which is arranged in a ring shape and forms a tooth ring opening. The linkage plate is embedded in the tooth ring opening, and the outer ring of the linkage plate forms a linkage tooth set, which is arranged in a ring shape and meshes with the fixing tooth set.

[0013] Furthermore, the lens housing assembly includes an outer shell and an inner shell, which are sleeved and movably assembled. The outer shell has multiple fixed platforms and multiple fixed plates, each fixed platform corresponding to each adjustable column, and one end of the adjustable column is mated to the fixed platform. The rotating component includes a rotating plate and a rotating column, the adjustable column passing through the rotating plate, the inner end of the rotating column mating to the rotating plate, and the outer end of the rotating column extending away from the rotating plate and embedded in the fixed platform.

[0032] Reference Figure 1-12 The image shown is a preferred embodiment of the present invention.

[0033] Example without a light shield:

[0034] A rotatable zoom lens module includes a moving assembly 1, a swing assembly 2, a lens housing assembly 3, and a lens body 4. The lens body 4 is mounted on the lens housing assembly 3. The swing assembly 2 is assembled with the lens housing assembly 3 and is used to drive the lens housing assembly 3 to swing. The moving assembly 1 includes a rotating component 11, a fixed component 12, and multiple adjusting posts 13. The rotating component 11 is assembled with the lens housing assembly 3 and movably assembled with the fixed component 12. One end of the adjusting post 13 is fixed, and the other end of the adjusting post 13 passes through the rotating component 11 and is docked with the fixed component 12. The adjusting post 13 has multiple adjusting slots 131, and each adjusting slot 131 is arranged at intervals along the axial direction. The rotating component 11 is relatively fixed with one of its adjusting slots 131.

[0035] The aforementioned rotatable zoom lens module drives the lens housing assembly 3 to swing via the swing assembly 2, causing the lens body 4 to swing left and right relative to the light source 5, thereby adjusting the projection angle of the lamp. Simultaneously, the rotating component 11 enables the lens housing assembly 3 to rotate circumferentially, which in turn drives the lens body 4 to rotate circumferentially, allowing adjustment of the projection direction along the circumferential direction. Furthermore, the interaction between the rotating component 11 and different adjustment slots 131 allows adjustment of the distance between the rotating component 11 and the fixed plate 121, thereby adjusting the distance between the lens body 4 and the light source 5, and thus adjusting the focal length of the light source 5. In this way, the illumination angle and focal length of the lamp can be flexibly adjusted according to the needs of the lighting scene, and the focusing effect of the lamp can be improved.

[0036] The rotatable zoom lens module includes a light source 5, which is used to emit light. The light source 5 is installed inside the light shield 6 and is arranged in a corresponding manner with the lens body 4. The light source 5 emits light to the lens body 4 and is projected outward through the lens body 4 to form a light spot.

[0037] The rotatable zoom lens module includes a light source frame for assembling the light source component 5. The light source frame and the light shield 6 are fixedly arranged to realize the assembly of the light source frame and the light source component 5; or, the light source frame and the fixing plate 121 are fixedly arranged to realize the assembly of the light source frame and the light source component 5.

[0038] The rotating component 11 has a rotating opening 112, which is arranged in a through manner, and the adjusting column 13 passes through the rotating opening 112. The rotating component 11 includes a fixed groove portion 111, which is located in the rotating opening 112 and is arranged to protrude outward. The fixed groove portion 111 is used to embed the adjusting groove 131.

[0039] In this way, the rotating port 112 facilitates the through-layout of the adjusting column 13, enabling the setting of the adjusting column 13. At the same time, the adjusting column 13 plays a positioning role on the rotating part 11 in the opposite direction, improving the cooperation effect between the rotating part 11 and the fixed part 12. Furthermore, through the cooperation between the fixed groove 111 and the adjusting groove 131, the position positioning between the rotating part 11 and the fixed part 12 is achieved, completing the focusing positioning.

[0040] The rotating component 11 includes multiple fixed grooves 111, each fixed groove 111 is arranged in a circumferential interval around the center of the rotating opening 112, and each fixed groove 111 is convexly arranged towards the center of the rotating opening 112. The adjustment groove 131 is arranged in a circumferential arrangement, and each fixed groove 111 is used to synchronously embed the adjustment groove 131.

[0041] In this way, with the synchronous positioning of multiple fixed slots 111, the relative fixation effect between the rotating part 11 and the fixed part 12 is ensured, and the stability of the focus adjustment is guaranteed.

[0042] The rotating component 11 has multiple rotating openings 112, and each rotating opening 112 is arranged in a one-to-one correspondence with each adjusting column 13. Each rotating opening 112 is provided with multiple fixed grooves 111. In this way, the setting of multiple adjusting columns 13 is realized, and the adjustment stability of the focal length is adjusted.

[0043] The adjustment slot 131 has an adjustment wall, which is arranged in an inwardly concave arc shape. The fixed slot part 111 is arranged in an arc shape, and the fixed slot part 111 is arranged in an outward arc shape. This makes it easy for the fixed slot part 111 to enter or leave the adjustment slot 131, ensuring the stability of the focal length adjustment. At the same time, it is easy to switch between the fixed slot part 111 and different adjustment slots 131, thereby realizing the adjustment of the focal length.

[0044] The rotating component 11 has three rotating ports 112, which are arranged correspondingly along a triangle. The moving assembly 1 includes three adjusting posts 13, which are arranged correspondingly along a triangle. The three adjusting posts 13 and the three rotating ports 112 are arranged in a one-to-one through-corresponding manner. In this way, the adjusting stability of the rotating component 11 is improved, ensuring the normal use of the lamp.

[0045] The rotating component 11 has two rotating ports 112, which are arranged symmetrically. The moving assembly 1 includes two adjusting columns 13, which are arranged symmetrically. The two adjusting columns 13 and the two rotating ports 112 are arranged in a one-to-one correspondence. This improves the adjusting stability of the rotating component 11 and ensures the normal use of the lamp.

[0046] The rotating component 11 has four rotating ports 112, which are arranged correspondingly along the four corners. The moving assembly 1 includes four adjusting posts 13, which are arranged correspondingly along the four corners. The four adjusting posts 13 and the four rotating ports 112 are arranged in a one-to-one through-corresponding manner. In this way, the adjusting stability of the rotating component 11 is improved, and the normal use of the lamp is guaranteed.

[0047] The fixing component 12 includes a fixing plate 121 and a linkage plate 122. The fixing plate 121 and the linkage plate 122 are sleeved and movable. The fixing plate 121 is assembled with the light shield 6. The linkage plate 122 is docked with the other end of the adjusting column 13. The linkage plate 122 is linked with the rotating component 11.

[0048] In this way, the assembly between the fixing plate 121 and the light shield 6 is realized through the fixing plate 121, and the circumferential rotation of the lens body 4 is easily adjusted through the cooperation between the linkage plate 122 and the rotating part 11.

[0049] When making rotational adjustments, a rotational force can be applied to the linkage plate 122 or the rotation plate 113. Of course, the rotational force can be applied to the linkage plate 122 and the rotation plate 113 simultaneously; this allows for adjustment of the circumferential rotation of the lens body 4, thereby adjusting the projection direction of the lamp.

[0050] Specifically, for rotational drive, an electric motor can be used to achieve electric drive, or a rotational force can be applied manually.

[0051] The fixed plate 121 has a fixed gear set, which is arranged in a ring and forms a gear ring opening. The linkage plate 122 is fitted with the gear ring opening, and the outer ring of the linkage plate 122 forms a linkage gear set, which is arranged in a ring and meshes with the fixed gear set. This makes the rotation adjustment more precise, and different angles can be selected for adjustment based on the needs.

[0052] Furthermore, the rotation of the rotating plate 113 can be a 360-degree rotation.

[0053] The lens body 4 has an entrance cavity 41 and an exit section. The entrance cavity 41 is arranged correspondingly to the light source 5. The entrance cavity 41 is arranged in a flared shape along the direction towards the light source, and the entrance cavity 41 is flared to the edge of the lens. The exit section is used to receive the light passing through the entrance cavity 41 and project the light outward.

[0054] Since the light inlet cavity 41 is arranged in an flared shape along the direction towards the light source, the opening of the light inlet cavity 41 is increased, and the light inlet cavity 41 is arranged with a large opening. Even when the light source is far away, most of the light can be hit into the light inlet hole, thereby improving the light efficiency.

[0055] The light-incident cavity 41 includes two light-incident side surfaces and a light-incident arc surface. The light-incident arc surface is arranged in an arc shape along the direction towards the light source. The light-emitting part includes a total reflection surface and a light-emitting surface. The light-incident side surfaces are used to refract light to the total reflection surface, the light-incident arc surface is used to refract light to the light-emitting surface, and the total reflection surface is used to reflect light to the light-emitting surface. The light is projected by the light-emitting surface to form a light spot. The light-incident arc surface is located between the two light-incident side surfaces, and the two light-incident side surfaces are arranged in a gradually inclined extension along the direction towards the light source.

[0056] With the combined effect of the light-incident side, the light-incident curved surface, the total reflection surface, and the light-exiting surface, most of the light rays are emitted in a cross pattern, making the light softer and the light spot more concentrated. There is less light interception, which improves the anti-glare ability. At the same time, the change in the light spot pattern is significantly smaller, which improves the uniformity of the light spot, achieves the effect of no yellow spots and reduces stray light, and brings good light transmission effect, so that the emitted light spot has a clear and good color effect.

[0057] The light-receiving side is arranged in a smooth shape to improve light transmission and thus enhance light efficiency.

[0058] Alternatively, a microstructure can be provided on the light-incident side, with the microstructure arranged in a frosted manner to improve the light mixing effect of the lens.

[0059] Alternatively, the microstructures can be arranged in a scale-like pattern to improve the light mixing effect of the lens.

[0060] Example of a light shield:

[0061] The rotatable zoom lens module includes a light shield 6, a moving assembly 1, a swing assembly 2, a lens housing 3, and a lens body 4, which are respectively located inside the light shield 6. The fixing member 12 is fixedly assembled with the light shield 6, and the rotating member 11 is movably assembled with the light shield 6. The rotating member 11 is driven to rotate in a circular manner relative to the fixing member 12, and the rotating member 11 is used to synchronously drive the lens housing 3 to rotate in a circular manner.

[0062] In this way, by applying a driving force to the rotating component 11, the rotating component 11 rotates in a circle relative to the fixed component 12, which in turn drives the lens body 4 to rotate in a circle, thereby adjusting the projection direction of the lamp in the horizontal direction.

[0063] Example of a motorless swing assembly:

[0064] The lens housing assembly 3 includes an outer shell 31 and an inner shell 32, which are fitted together and movably assembled. The outer shell 31 is provided with multiple fixed posts and multiple fixed plates. Each fixed post is arranged in a one-to-one correspondence with each adjustable post 13, and one end of the adjustable post 13 is connected to the fixed post. The rotating component 11 includes a rotating plate 113 and a rotating post 114. The adjustable post 13 passes through the rotating plate 113, and the inner end of the rotating post 114 is connected to the rotating plate 113. The outer end of the rotating post 114 extends in a direction away from the rotating plate 113 and is embedded in the fixed plate.

[0065] The outer shell 31 enables the separate setting of the rotating plate 113 and the adjusting column 13, while the inner shell 32 enables the assembly of the lens body 4.

[0066] The lens body 4 is mounted on the inner shell 32. The swing assembly 2 includes a swing gear 21. The swing gear 21 is assembled with the inner shell 32. The swing gear 21 is rotated under driving force. The swing gear 21 is used to drive the inner shell 32 to swing relative to the outer shell 31.

[0067] In this way, by driving the swing gear 21, the inner shell 32 is driven to swing, thereby causing the lens body 4 to swing, thus realizing the adjustment of the projection angle of the lens body 4.

[0068] The inner shell 32 includes a flat shell shaft 321 with a flat cross-section. The flat shell shaft 321 passes through the oscillating gear 21 and is arranged at a relatively high height relative to the oscillating gear 21. In this way, the rotation of the oscillating gear 21 drives the flat shell shaft 321 to rotate, thereby realizing the oscillation of the inner shell 32, which in turn drives the lens body 4 to oscillate.

[0069] The flat shell shaft 321 has two axial tangent surfaces and two axial arc surfaces. The two axial tangent surfaces are arranged in a corresponding manner, and the two axial arc surfaces are arranged in a corresponding manner. The two axial arc surfaces are arranged in an arched arc shape along opposite directions. The two ends of the axial tangent surface are respectively arranged to meet the two axial arc surfaces, and the axial tangent surface is arranged to extend vertically along the axial direction. The oscillating gear 21 has a gear hole. The axial tangent surface passes through the gear hole and penetrates the oscillating gear 21. Both the axial tangent surface and the axial arc surface are arranged to lie flat and abut against the gear hole.

[0070] In this way, the rotation of the oscillating gear 21 can effectively drive the flat shell shaft 321 to rotate, thereby adjusting the projection angle and avoiding the idling of the oscillating gear 21, thus ensuring the adjustment of the projection angle of the lamp.

[0071] Example of a swing assembly with a motor:

[0072] The oscillating assembly 2 includes an oscillating motor, which has a motor shaft and a motor gear. The motor gear and the oscillating gear 21 are assembled together. The motor gear applies a driving force to the oscillating gear 21, thereby realizing the rotation of the oscillating gear 21.

[0073] Furthermore, the lens body 4 is oscillated by the rotation of the oscillating gear 21, which improves the adjustment accuracy.

[0074] The inner shell 32 includes a flat shell shaft 321 with a flat cross-section. The flat shell shaft 321 passes through the oscillating gear 21 and is arranged at a relatively high height relative to the oscillating gear 21. In this way, the rotation of the oscillating gear 21 drives the flat shell shaft 321 to rotate, thereby realizing the oscillation of the inner shell 32, which in turn drives the lens body 4 to oscillate.

[0075] The flat shell shaft 321 has two axial tangent surfaces and two axial arc surfaces. The two axial tangent surfaces are arranged in a corresponding manner, and the two axial arc surfaces are arranged in a corresponding manner. The two axial arc surfaces are arranged in an arched arc shape along opposite directions. The two ends of the axial tangent surface are respectively arranged to meet the two axial arc surfaces, and the axial tangent surface is arranged to extend vertically along the axial direction. The oscillating gear 21 has a gear hole. The axial tangent surface passes through the gear hole and penetrates the oscillating gear 21. Both the axial tangent surface and the axial arc surface are arranged to lie flat and abut against the gear hole.

[0076] In this way, the rotation of the oscillating gear 21 can effectively drive the flat shell shaft 321 to rotate, thereby adjusting the projection angle and avoiding the idling of the oscillating gear 21, thus ensuring the adjustment of the projection angle of the lamp.

[0077] The oscillating assembly adopts a gear-based embodiment:

[0078] The oscillating assembly 2 includes an oscillating gear 21, which is assembled with the lens housing assembly 3. The oscillating gear 21 is used to drive the lens housing assembly 3 to oscillate relative to each other. The lens housing assembly 3 includes an outer shell 31 and an inner shell 32, which are fitted together and movably assembled. Thus, by driving the oscillating gear 21, the inner shell 32 is driven to oscillate, thereby causing the lens body 4 to oscillate, thereby adjusting the projection angle of the lens body 4.

[0079] Gearless embodiment of the oscillating assembly:

[0080] The swing assembly 2 includes a swing shaft 22, which passes through the lens housing assembly 21. The swing shaft 22 is rotated under driving force and is used to drive the lens housing assembly 3 to swing. The lens housing assembly 3 includes an outer shell 31 and an inner shell 32, which are fitted together and movably assembled. Thus, by driving the swing gear 21, the inner shell 32 is driven to swing, thereby driving the lens body 4 to swing, thereby adjusting the projection angle of the lens body 4.

[0081] Example of stepless zoom:

[0082] The stepless zoom lens module includes a moving assembly 1, a swing assembly 2, a lens housing assembly 3, and a lens body 4. The lens body 4 is mounted on the lens housing assembly 3. The swing assembly 2 is assembled with the lens housing assembly 3 and is used to drive the lens housing assembly 3 to swing. The moving assembly 1 includes a rotating component 11, a fixed component 12, at least one adjusting post 13, and at least one zoom ring 14. The rotating component 11 and the fixed component 12 are movably assembled. One end of the adjusting post 13 is fixed, and the other end of the adjusting post 13 passes through the rotating component 11 and is connected to the fixed component 12. The zoom ring 14 is fitted with the adjusting post 13 and is elastically arranged. The zoom ring 14 is pressed against the fixed component 12 and is used to make the fixed component 12 and the rotating component 11 relatively fixed. When subjected to external force, the fixed component 12 and the zoom ring 14 move synchronously relative to the rotating component 11. When the fixed component 12 moves, the distance between the lens housing assembly 3 and the light source component changes.

[0083] The aforementioned stepless zoom lens module drives the lens housing assembly 33 to swing via the swing assembly 22, causing the lens body 44 to swing left and right relative to the light source 5, thereby adjusting the projection angle of the lamp. Simultaneously, the rotating component 1111 enables the lens housing assembly 33 to rotate circumferentially, which in turn drives the lens body 44 to rotate circumferentially, allowing adjustment of the projection direction along the circumferential direction. Furthermore, by changing the position between the zoom ring 14 and the fixing component 1212, the distance between the rotating component 1111 and the fixing plate 121 is adjusted, thereby adjusting the distance between the lens body 44 and the light source 5, thus adjusting the focal length of the light source 5 and achieving stepless zoom.

[0084] At the same time, users can flexibly adjust the illumination angle and focal length of the lamps according to the needs of the lighting scene, and improve the focusing effect of the lamps.

[0085] The fixing member 1212 includes a fixed housing 123, an adjusting column 13 passing through the inside of the fixed housing 123, and a zoom ring 14 located inside the fixed housing 123, with the zoom ring 14 and the fixed housing 123 arranged in a pressing manner; thus, stepless zoom is achieved by adjusting the relative position of the zoom ring 14 and the fixed housing 123.

[0086] The zoom rings 14 and the adjustment column 13 are arranged in a one-to-one correspondence. The coordination of multiple zoom rings 14 improves the stability and stability of focusing.

[0087] Of course, the single zoom column 13 is equipped with multiple zoom rings 14. Through the synchronous limitation of multiple zoom rings 14, erroneous zooming is avoided, ensuring the normal use of the stepless zoom lens module.

[0088] The continuously variable zoom oscillation assembly adopts a gear-based embodiment:

[0089] The oscillating assembly 2 includes an oscillating gear 21, which is assembled with the lens housing assembly 3. The oscillating gear 21 is used to drive the lens housing assembly 3 to oscillate relative to each other. The lens housing assembly 3 includes an outer shell 31 and an inner shell 32, which are fitted together and movably assembled. Thus, by driving the oscillating gear 21, the inner shell 32 is driven to oscillate, thereby causing the lens body 4 to oscillate, thereby adjusting the projection angle of the lens body 4.

[0090] Gearless embodiment of continuously variable zoom oscillating assembly:

[0091] The swing assembly 2 includes a swing shaft 22, which passes through the lens housing assembly 21. The swing shaft 22 is rotated under driving force and is used to drive the lens housing assembly 3 to swing. The lens housing assembly 3 includes an outer shell 31 and an inner shell 32, which are fitted together and movably assembled. Thus, by driving the swing gear 21, the inner shell 32 is driven to swing, thereby driving the lens body 4 to swing, thereby adjusting the projection angle of the lens body 4.

[0092] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
