Technical Field
[0001] This invention relates to the field of lens lighting device technology, specifically to a lens lighting device with multi-degree-of-freedom adjustment. Background Technology
[0002] Lens lighting devices utilize carefully designed optical lens assemblies placed in front of or around light sources (such as LEDs, xenon lamps, halogen lamps, etc.) to achieve precise control of the light source's light by refracting, focusing, or diffusing the light. This optimizes the light distribution, efficiency, and visual effects, and they are widely used in various lighting scenarios where high light quality is required.
[0003] The objects illuminated by lens lamps are not fixed in a single spatial position; their height, horizontal orientation, and placement angle all vary. However, the adjustment joints of ordinary lens lamps are usually locked with clips and screws. When adjusting manually, one can only repeatedly adjust the position of the light spot by observing the position of the light spot with the naked eye. Moreover, the operator's perspective during adjustment is inconsistent with the actual lighting perspective, making it impossible to accurately judge the position of the light spot in real time. Therefore, we propose a lens lamp device with multi-degree-of-freedom adjustment. Summary of the Invention

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Example 1 Please see Figures 1 to 8 The present invention provides a technical solution: a multi-degree-of-freedom adjustable lens lamp device, including a lamp body 1; a fixing base 2, and a rotating shaft 3 fixedly connected to the outside of the lamp body 1; an angle adjustment mechanism 4, located between the fixing base 2 and the rotating shaft 3, which adjusts the illumination position of the lamp body 1; and an auxiliary marking mechanism 5, located on the top of the lamp body 1, which reflects the illumination position of the lamp body 1 in real time when the angle adjustment mechanism 4 adjusts the angle of the lamp body 1.
[0019] During use, the operator initially fixes the mounting base 2 to the area to be installed using bolts. The lamp body 1 is connected to the adjustment frame 40 via the rotating shaft 3, ensuring that the auxiliary marking mechanism 5 is aligned with the lighting direction of the lamp. When adjusting the position of the illumination spot of the lamp body 1, the lamp body 1 is rotated horizontally 360° and tilted 0°~90° using the angle adjustment mechanism 4. After adjustment, the angle of the lamp body 1 is mechanically locked to ensure that there is no angle deviation after adjustment, meeting the lighting scene requirements. During the adjustment process, the operator can observe the position of the light spot of the lamp body 1 through the auxiliary marking mechanism 5 while adjusting the angle of the lamp body 1. The adjustment can be completed by a single person without the need for multiple people to cooperate, improving efficiency.
[0020] The angle adjustment mechanism 4 includes an adjustment frame 40, a rotating shaft 3 is rotatably connected to the inner wall of the adjustment frame 40, a limiting member 41 for limiting the rotating shaft 3 is provided on the side of the adjustment frame 40 near the rotating shaft 3, a storage tube 42 is fixedly connected to the end of the adjustment frame 40 near the fixed base 2, a rotating member 43 for driving the storage tube 42 to rotate is provided on the side of the fixed base 2 near the storage tube 42, and the storage tube 42 is located at the top center of the adjustment frame 40 to help to bundle the cable of the lamp body 1.
[0021] The angle adjustment of the lamp body 1 is divided into horizontal 360° rotation and pitch adjustment from 0° to 90°: When the lamp body 1 is rotated horizontally 360°, the rotating shaft 3 is fixed to the adjusting frame 40 by the limiting member 41, so that the operator drives the adjusting frame 40 to rotate horizontally by the rotating member 43. When the light spot of the lamp body 1 illuminates the surface of the object, the rotation speed of the rotating member 43 is slowed down to facilitate fine adjustment. When the lamp body 1 is tilted from 0° to 90°, the rotating part 43 is locked, and the fixing of the rotating shaft 3 and the adjusting frame 40 is achieved by the limiting part 41. Thus, the operator can adjust the tilt angle of the lamp body 1 to adjust the position of the light spot of the lamp body 1. By adjusting the horizontal and tilt angles, the light spot of the lamp body 1 can be focused to the predetermined position.
[0022] The rotating component 43 includes a transmission gear 44 fixedly connected to the outside of the storage cylinder 42. An adjusting gear 45 meshes with the outside of the transmission gear 44. A transmission rod 46 is fixedly connected to the center of the adjusting gear 45. The transmission rod 46 is rotatably connected to the fixed base 2. An adjusting rod 47 is slidably connected to the inner wall of the transmission rod 46. A locking block 48 is fixedly connected to the outside of the adjusting rod 47. The locking block 48 is slidably connected to the inner wall of the transmission rod 46. A slot 49 is provided on the inner wall of the fixed base 2, which is slidably connected to the locking block 48. A reset plate 410 is rotatably connected to the end of the adjusting rod 47 near the slot 49. The reset plate 410 is slidably connected to the inner wall of the fixed base 2. A reset spring 411 is fixedly connected to the end of the reset plate 410 away from the adjusting rod 47. The end of the reset spring 411 away from the reset plate 410 is fixed to the inner wall of the fixed base 2.
[0023] When adjusting the horizontal angle, pull the adjusting rod 47 outward to disengage the locking block 48 from the slot 49; rotate the adjusting rod 47, which drives the transmission rod 46 to rotate synchronously through the locking block 48. The transmission rod 46 drives the adjusting gear 45 to rotate. The meshing transmission between the adjusting gear 45 and the transmission gear 44 drives the storage cylinder 42 and the adjusting frame 40 to rotate horizontally, and the lamp body 1 rotates synchronously to the target horizontal position. After the adjusting rod 47 is released, the reset spring 411 drives the reset plate 410 to reset, the reset plate 410 drives the adjusting rod 47 to reset, and the adjusting rod 47 drives the locking block 48 to lock into the locking slot 49, locking the horizontal angle.
[0024] The limiting component 41 includes a fixed cylinder 412 fixedly connected to the adjusting frame 40. A connecting groove 413 is provided on the inner wall of the fixed cylinder 412. A threaded rod 414 is provided on the inner wall of the connecting groove 413. One end of the threaded rod 414 passes through the fixed cylinder 412 and communicates with the outside. The threaded rod 414 is threadedly connected to the inner wall of the fixed cylinder 412. A compression ring 415 is slidably connected to the inner wall of the connecting groove 413. The compression ring 415 is rotatably connected to the threaded rod 414. Multiple limiting blocks 416 are slidably connected to the inner wall of the connecting groove 413. A spring plate 417 is fixedly connected to the outer side of the limiting block 416. The spring plate 417 is fixed to the inner wall of the connecting groove 413. The multiple limiting blocks 416 are distributed at equal angles. The end of the limiting block 416 near the compression ring 415 is a trapezoidal end. The side of the compression ring 415 near the limiting block 416 has an arc end 418.
[0025] When adjusting the pitch angle, rotate the threaded rod 414, and the compression ring 415 moves toward the limiting block 416. The limiting block 416 clamps the rotating shaft 3 and locks the current pitch angle. If adjustment is needed, rotate the threaded rod 414 in the opposite direction. After the limiting block 416 is reset, rotate the lamp body 1 to the target pitch angle, and then tighten the threaded rod 414 to lock it.
[0026] The auxiliary marking mechanism 5 includes an observation tube 50 fixedly connected to the lamp body 1. An objective lens 51 is fixedly connected to the end of the observation tube 50 near the illumination part of the lamp body 1, and an eyepiece 52 is fixedly connected to the end of the observation tube 50 away from the objective lens 51. A reflector 53 is installed on the inner wall of the observation tube 50. The angle between the incident light of the objective lens 51 and the reflector 53 is equal to the angle between the incident light of the eyepiece 52 and the reflector 53.
[0027] During the angle adjustment process, the objective lens 51 captures the light spot image of the illuminated target in real time, which is reflected by the mirror 53 to the eyepiece 52. The operator observes the alignment of the light spot with the target through the eyepiece 52, and fine-tunes the angle until the light spot accurately covers the target, thus completing the precise positioning.
[0028] Example 2 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the rotating shaft 3 has friction grooves 6 on the side near the limiting block 416, and the end of the limiting block 416 near the rotating shaft 3 is a rubber block 7. When the compression ring 415 pushes the limiting block 416 close to the rotating shaft 3, the rubber block 7 end of the limiting block 416 compresses the rotating shaft 3 and deforms, which increases the friction between the rubber block 7 and the friction grooves 6, so as to limit the rotation angle of the lamp body 1 in the vertical direction.
