Description

Technical Field

[0001] The present invention relates to the field of light source brightness adjustment, and more specifically, to a shape light machine for light source brightness adjustment. Background Art

[0002] When the optical machine emits light from the inside to the outside, it must ensure that the light intensity at the light source is suitable for the brightness of the current use environment, and also ensure that the projected light source can have a clearer picture. Therefore, the focal length needs to be adjusted. In a dark environment, the ambient brightness is large, and the brightness of the projected picture needs to be improved. If it is weak, the clarity of the projected picture will be affected. The existing device cannot adjust the focal length at the same time while ensuring the intensity of the projected light. The two structures that need to be adjusted need to be adjusted separately at intervals, which is inconvenient to use and affects the viewing experience and use. Summary of the invention

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] In this solution, the outer frame lens is fitted onto the outer side of the inner lens, and the right-angle groove is engaged with the outer side structure of the inner lens, so that the outer frame lens can be easily removed from the outer side of the inner lens to facilitate cleaning of the lens surface at the front end of the outer frame lens. At the same time, the lens surface is blocked on the outer side of the inner lens, which can play a certain protective role.

[0019] In this solution, when the inner lens is screwed into the inner side of the optical machine body, the inner lens gradually approaches the adjustment end and squeezes the adjustment end to shrink toward the inner structure of the shrinking end. In this way, the distance between the above-mentioned transparent inner lens and the shrinking mirror surface is changed, thereby playing the role of adjusting the focal length.

[0020] In this solution, the sliding end of the fixed ring is driven to move by contracting the fixed ring, and then the sliding end of the fixed ring moves to pull the slide ladder block and slide with the inclined slide groove on the side of the slide ladder block. When the sliding end of the fixed ring moves to different positions of the slide ladder block, due to the different thicknesses of the slide ladder block, the angle at which the reflector flips around the rotating vertical axis changes, thereby changing the overall angle of the reflector, thereby achieving the effect of adjusting the illumination intensity of the internal light source.

[0021] In this solution, when the reflector is retracted inward, the light passing through the reflector will become less and will be reflected back by the mirror on the back of the reflector to reduce the brightness of the light source. In a dark place, the reflector is opened outward to allow light to illuminate the other side of the reflector and allow the light from the light source to be gathered through the flatter side of the reflector to increase the brightness in turn. The brightness can be increased while coordinating with the focal length adjustment to achieve the purpose of joint adjustment.

[0022] In this solution, when the adjustment end moves, the sliding end seat rod will be extended to push the linkage rod, and the linkage rod will push the spring contraction rod and the fixed frame inside the optical machine to slide. At this time, the light source fixing plate moves together with the spring contraction rod. When the spring contraction rod moves to the extreme position of the fixed frame inside the optical machine, the linkage rod will no longer be moved and will continue to push, so that the light source fixing plate and the reflective structure gradually approach each other, thereby changing the distance between the light source and the reflective structure, and further changing the intensity of the irradiated light.

When the inner lens 11 is screwed into the inner side of the optical machine body 1, the inner lens 11 gradually approaches the adjusting end 5 and squeezes the adjusting end 5 to shrink toward the inner structure of the retractable end 6. In this way, the distance between the above-mentioned transparent inner mirror 13 and the retractable mirror surface 18 is changed, thereby playing the role of adjusting the focal length.

[0040] See also Figure 4 and Figure 5The outer side surface of the retractable end 6 is provided with a through rod end 21, and a slide bar groove is opened on the side of the through rod end 21. The sliding end seat rod 20 is a short slide bar perpendicular to the rod body, and the short slide bar and the slide bar groove constitute a sliding structure. The inner side surface of the retractable end 6 is provided with a reflective structure 22. The retractable end 6 is fixedly connected to the inner wall of the optical machine body 1. When the adjusting end 5 moves toward the retractable end 6, the outer side of the adjusting end 5 drives the sliding end seat rod 20 and the through rod end 21 to perform structural contraction, thereby driving the reflective structure 22 inside the retractable end 6 to operate, so as to adjust the brightness of the internal light source.

When the fixed ring sliding end 30 moves to different positions of the slide ladder block 29, due to the different thicknesses of the slide ladder block 29, the flipping angle of the reflector 27 around the rotating vertical axis 25 changes, thereby changing the overall angle of the reflector 27, thereby achieving the effect of adjusting the illumination intensity of the internal light source.

[0042] See also Figure 7 and Figure 8 A reflector 27 is fixedly connected to the side of the rotating rod 26, and a slide ladder block 29 is fixedly connected to the side of the reflector 27. An inclined slide is opened on the side of the slide ladder block 29, and a fixed ring sliding end 30 is slidably connected to the inner side of the inclined slide. The end of the fixed ring sliding end 30 is fixedly connected to a shrinking fixed ring 28, and the shrinking fixed ring 28 is fixedly connected to the slide rod of the sliding end seat rod 20. When the reflector 27 is retracted inward, the light passing through the reflector 27 will become less and will be reflected back by the mirror surface on the back of the reflector 27 to reduce the brightness of the light source. In a dark place, the reflector 27 is opened outward to allow light to illuminate the other side of the reflector 27, and the light of the light source is gathered through the relatively flat side of the reflector 27 to increase the brightness in turn. The brightness is increased and the focal length is adjusted at the same time to achieve the purpose of joint adjustment.

[0043] See also Fig. 9The fixed end 31 of the light source includes a linkage rod 32, a spring retracting rod 33, an optical machine internal fixed frame 34, a light source fixing plate 35, and a fixed right-angle platform 36.

It is fixedly connected with a light source fixing plate 35. When the adjustment end 5 moves, the sliding end seat rod 20 will be pulled out to push the linkage rod 32. The linkage rod 32 will push the spring contraction rod 33 and the fixed frame 34 inside the optical machine to slide. At this time, the light source fixing plate 35 moves together with the spring contraction rod 33. When the spring contraction rod 33 moves to the extreme position of the fixed frame 34 inside the optical machine, the linkage rod 32 will no longer be moved and will continue to push, so that the light source fixing plate 35 and the reflective structure 22 are gradually approached, thereby changing the distance between the light source and the reflective structure 22, and further changing the intensity of the irradiated light.

[0044] When in use: first, the driving motor 4 drives the meshing side arc teeth 9 to rotate through the gear connected to the output shaft, and then the outer frame lens 8 and the inner lens 11 inside rotate at the same time, so that the inner lens 11 screws the optical machine lens 2 as a whole into the inner side of the optical machine body 1 through the threaded lens ring 16 at the rear end, and then when the inner lens 11 is screwed into the inner side of the optical machine body 1, the inner lens 11 gradually approaches the adjustment end 5, and squeezes the adjustment end 5 to shrink toward the inner structure of the contraction end 6, and then drives the movement of the contraction fixed ring 28 to drive the movement of the fixed ring sliding end 30, and then the fixed ring sliding end 30 moves to pull the slide ladder block 29, and slides with the inclined slide on the side of the slide ladder block 29. When the fixed ring sliding end 30 moves to different positions of the slide ladder block 29, due to the different thicknesses of the slide ladder block 29, the flipping angle of the reflector 27 around the rotating vertical axis 25 changes. When the reflector 27 is retracted inward, the light passing through the reflector 27 will become less and will be reflected back by the mirror on the back of the reflector 27 to reduce the brightness of the light source. In a dark place, the reflector 27 is opened outward to allow light to illuminate the other side of the reflector 27 and allow the light from the light source to be gathered through the relatively flat side of the reflector 27 to increase the brightness in turn. The brightness is increased while coordinating with the focal length adjustment. Finally, when the adjustment end 5 moves, the sliding end seat rod 20 will be pulled out to push the linkage rod 32. The linkage rod 32 will push the spring retraction rod 33 and the optical machine inner frame 34 to slide. At this time, the light source fixing plate 35 moves together with the spring retraction rod 33. When the spring retraction rod 33 moves to the limit position of the optical machine inner frame 34, the linkage rod 32 is no longer moved and continues to push, so that the light source fixing plate 35 and the reflective structure 22 are gradually approached.
