Description

Technical Field

[0001] This utility model belongs to the field of lighting equipment technology, and specifically relates to an adjustable lighting device. Background Technology

[0002] Lighting equipment is a general term for various professional instruments used to generate, control, and shape light. Its core functions are to provide necessary lighting, create specific atmospheres, shape visual focal points, convey information, or create dynamic effects. It is widely used in many fields such as stage performances, film and television production, architectural and landscape lighting, exhibitions, commercial spaces, entertainment venues, and daily lighting. It is an indispensable key technical equipment in modern visual arts, information dissemination, and spatial environment shaping.

[0003] According to Chinese Patent Publication No. CN215576049U, an adjustable lighting device for a live streaming room is disclosed. The adjustable lighting device for a live streaming room includes a mounting box with an opening at the bottom; a bottom cover fixedly installed at the bottom opening of the mounting box, and the bottom cover has a strip-shaped sliding hole; an illumination lamp located below the bottom cover, and a mounting bracket rotatably mounted on the illumination lamp; a moving mechanism located on the mounting box; and an adjustment mechanism located below the mounting box and above the illumination lamp.

[0004] However, the aforementioned devices, when combined with existing lighting equipment, all have drawbacks. Specifically, in small live-streaming sales sessions, lighting equipment is necessary to illuminate the products. Since the hosts need to showcase a wide variety of products of varying sizes, small items, such as jewelry and cosmetic samples, require a smaller lighting area to focus on the product itself, avoiding wasted light and an overly bright background. Medium-sized items, such as ornaments and daily necessities, require a larger lighting area to ensure the entire product is illuminated without shadows or blind spots. Due to limitations in adjusting the lighting range of existing equipment, when switching from displaying small to medium-sized products, the current lighting cannot fully illuminate the medium-sized product, leaving some areas in shadow. Viewers cannot clearly see the product's full appearance and details, reducing its appeal. Conversely, when switching from displaying medium to small products, an excessively large lighting area can also illuminate the background, distracting viewers and potentially making small products appear less prominent due to overly diffused light. Utility Model Content

[0005] In view of the problem that the illumination range of the light cannot be adjusted according to the different sizes of the goods in the related technology, this utility model proposes an adjustable lighting device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is an adjustable lighting device, including a base plate. An angle adjustment mechanism is provided at one end of the base plate. A horizontal reflector mechanism is provided at the adjustment end of the angle adjustment mechanism. A light body is provided inside the horizontal reflector mechanism. A synchronous drive mechanism is provided at the horizontal end of the horizontal reflector mechanism. An aperture mechanism is provided at the drive end of the synchronous drive mechanism.

[0008] By rotating the drive end of the synchronous drive mechanism, the drive end synchronously drives the transverse end of the transverse reflector mechanism and the aperture mechanism to rotate synchronously, so that while the transverse end drives the light body to move inside the transverse reflector mechanism, the aperture end of the aperture mechanism opens and closes synchronously.

[0009] Furthermore, the angle adjustment mechanism includes a turntable, which is rotatably connected to the surface of the base plate. A fixed rod is fixedly connected to one end of the turntable. Several balls are slidably connected inside the base plate. A spring is provided on one side of each ball. One end of the spring is fixedly connected to the inside of the base plate. Several positioning grooves adapted to the balls are opened on the surface of the turntable, and the balls are engaged in the positioning grooves.

[0010] Furthermore, a stabilizing frame is fixedly connected to one end of the fixing rod, a fixed shell is rotatably connected inside the stabilizing frame, an adjusting ring is fixedly connected to the surface of the fixed shell, and the adjusting ring is slidably connected inside the stabilizing frame.

[0011] Furthermore, the stabilizer has several sliding blocks inside, and a second spring is fixedly connected to one side of each block. One end of the second spring is fixedly connected inside the stabilizer. The adjusting ring surface has several fixing holes that are adapted to the blocks, and the blocks engage in the fixing holes.

[0012] Furthermore, the transverse reflector mechanism includes a reflector cup, which is fixedly connected to one side of the fixed shell. A mounting bracket is slidably connected inside the reflector cup. The light body is fixedly mounted on the surface of the mounting bracket. An adjusting screw is rotatably connected to one side of the mounting bracket. A gear is rotatably connected inside the reflector cup, and the gear is threadedly connected to the adjusting screw.

[0013] Furthermore, the synchronous drive mechanism includes a handle, a chain meshing on the surface of the first gear, a second gear meshing inside the chain, one end of the second gear being fixedly connected to the handle, and the other end of the second gear being fixedly connected to a synchronous pulley, and the handle being rotatably connected inside the fixed housing.

[0014] Furthermore, the aperture mechanism includes a gear ring that meshes with a synchronous pulley. The gear ring is rotatably connected inside the reflector cup. An aperture plate is fixedly connected inside the gear ring. Several arc-shaped blades are slidably connected to the surface of the aperture plate. A connecting plate is fixedly connected inside the reflector cup. One end of each of the arc-shaped blades is rotatably connected to the surface of the connecting plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model uses a rotating synchronous drive mechanism to drive the lateral end of the transverse reflector mechanism to rotate synchronously. This causes the lateral end to drive the light body to move axially within the transverse reflector mechanism, thereby changing the position of the light body's light-emitting focal point. This alters the focal length ratio between the light body's light-emitting focal point and the parabolic reflector cup. By utilizing the reflective properties of the curved surface, the diffused light emitted by the light body is focused into a specific direction or area, thus adjusting the light body's illumination range to suit the lighting needs of products of different sizes.

[0017] 2. This utility model, by rotating the handle, drives gear two to rotate. Gear two drives gear one to rotate via a chain, which in turn drives a synchronous wheel to rotate. The synchronous wheel drives a gear ring to rotate, causing the gear ring to move the aperture plate and several arc-shaped blades along the surface of the connecting plate, changing the size of the light hole in the center of the blades. Gear one drives the adjusting screw to move axially, causing the mounting bracket and the light body to move laterally inside the reflector cup, achieving synchronous driving. When the light body moves into the reflector cup, the light source is closer to the bottom of the reflector cup, and the light is reflected and focused, enhancing the light. The light hole shrinks synchronously to further limit divergence, improving the focusing effect and accurately illuminating small products. When the light body moves outward, the light source is away from the bottom, and the light divergence angle increases after reflection, the light hole enlarges synchronously, and the illumination range expands, meeting the lighting needs of medium-sized products. Through the coordinated adjustment of the reflector cup and the light hole, compared to adjusting the reflector cup or the light hole alone, it is possible to switch between different illumination ranges more quickly and accurately, and the adjustment process is continuous. The anchor does not need to frequently manually operate multiple components, reducing the impact on the continuity of the live broadcast.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0030] Please see Figures 1-6As shown, this utility model is an adjustable lighting device, including a base plate 1, an angle adjustment mechanism 3 is provided at one end of the base plate 1, a horizontal moving reflector mechanism 4 is provided at the adjustment end of the angle adjustment mechanism 3, a light body 2 is provided inside the horizontal moving reflector mechanism 4, a synchronous drive mechanism 5 is provided at the horizontal moving end of the horizontal moving reflector mechanism 4, and an aperture mechanism 6 is provided at the drive end of the synchronous drive mechanism 5.

[0031] By rotating the drive end of the synchronous drive mechanism 5, the drive end synchronously drives the transverse end of the transverse reflector mechanism 4 and the aperture mechanism 6 to rotate synchronously, so that while the transverse end drives the light body 2 to move inside the transverse reflector mechanism 4, the aperture end of the aperture mechanism 6 opens and closes synchronously.

[0032] The light body 2 inside the transverse reflector mechanism 4 is adjusted at multiple angles by the adjustment end of the angle adjustment mechanism 3. The drive end of the rotation synchronous drive mechanism 5 is used to drive the transverse end of the transverse reflector mechanism 4 and the aperture mechanism 6 to rotate synchronously. This allows the transverse end to drive the light body 2 to move inside the transverse reflector mechanism 4 while the aperture end of the aperture mechanism 6 opens and closes synchronously, thereby adjusting and changing the illumination range of the light body 2.

[0033] By rotating the drive end of the synchronous drive mechanism 5, the drive end synchronously drives the transverse end of the transverse reflector mechanism 4 to rotate, so that the transverse end drives the light body 2 to translate and move axially inside the transverse reflector mechanism 4, thereby changing the position of the light-emitting focal point of the light body 2, thereby changing the focal length ratio between the light-emitting focal point of the light body 2 and the parabolic reflector cup 401. By utilizing the reflection characteristics of the curved surface, the diffused light emitted by the light body 2 is focused to a specific direction or area, thereby adjusting the illumination range of the light body 2 to adapt to the lighting needs of products of different sizes.

[0034] In one embodiment, the angle adjustment mechanism 3 includes a turntable 301 rotatably connected to the surface of a base plate 1. A fixing rod 302 is fixedly connected to one end of the turntable 301. A plurality of balls 303 are slidably connected inside the base plate 1. A spring 304 is provided on one side of each ball 303, with one end of the spring 304 fixedly connected to the inside of the base plate 1. A plurality of positioning grooves 305 adapted to the balls 303 are formed on the surface of the turntable 301, and the balls 303 engage in the positioning grooves 305. The fixing rod 302... A stabilizing frame 306 is fixedly connected to one end. A fixed shell 307 is rotatably connected inside the stabilizing frame 306. An adjusting ring 308 is fixedly connected to the surface of the fixed shell 307. The adjusting ring 308 is slidably connected inside the stabilizing frame 306. Several locking blocks 309 are slidably connected inside the stabilizing frame 306. A second spring 310 is fixedly connected to one side of the locking block 309. One end of the second spring 310 is fixedly connected inside the stabilizing frame 306. Several fixing holes 311 that are adapted to the locking blocks 309 are opened on the surface of the adjusting ring 308. The locking blocks 309 are engaged in the fixing holes 311.

[0035] The turntable 301 and the stabilizer 306 are fixed by the fixing rod 302. Rotating the turntable 301 causes it to press the ball bearing 303 and the first spring 304. When the turntable 301 rotates to a certain angle, the first spring 304 drives the ball bearing 303 to engage in the positioning groove 305, thus stabilizing the turntable 301. Flipping the fixing shell 307 causes the fixing shell 307 to drive the adjusting ring 308 to slide inside the stabilizer 306, while pressing the locking block 309 and the second spring 310. When the adjusting ring 308 rotates to a certain angle, the second spring 310 drives the locking block 309 to engage in the fixing hole 311, thus fixing the adjusting ring 308. This achieves multi-angle adjustment of the light body 2.

[0036] In one embodiment, the transverse reflector 4 includes a reflector cup 401, which is fixedly connected to one side of the fixed housing 307. A mounting bracket 402 is slidably connected inside the reflector cup 401. The light body 2 is fixedly mounted on the surface of the mounting bracket 402. An adjusting screw 403 is rotatably connected to one side of the mounting bracket 402. A gear 404 is rotatably connected inside the reflector cup 401, and the gear 404 is threadedly connected to the adjusting screw 403.

[0037] The rotation of gear 404 drives the adjusting screw 403 to move axially. The adjusting screw 403 causes the mounting bracket 402 to slide inside the reflector cup 401, and at the same time causes the lamp body 2 to move laterally inside the reflector cup 401.

[0038] The reflector cup 401 employs a curved structure, and its inner surface undergoes a special treatment with electroplated high-reflective material, giving it extremely strong light reflection capabilities. Utilizing the reflective properties of the curved surface, it converges the dispersed light emitted by the light source body 2 towards a specific direction or area. When the light source moves towards the bottom of the reflector cup 401, it gets closer to the focal area of ​​the reflector cup 401. At this time, most of the light emitted by the light source will strike the inner wall of the reflector cup 401 at an angle closer to the axis of the reflector cup 401. After reflection by the curved surface, the direction of light propagation will be more concentrated towards the axis of the reflector cup 401. This means that more light can emerge along approximately parallel or small-angle divergent paths, thereby greatly reducing the risk of light loss. The scattering range of light significantly enhances the light intensity within the irradiated area, resulting in a more pronounced focusing effect. When the light source moves away from the bottom of the reflector cup 401, it deviates from the optimal focusing area of ​​the reflector cup 401. At this point, the angle at which the light emitted by the light source strikes the inner wall of the reflector cup 401 becomes more dispersed. After reflection, the direction of light propagation exhibits a larger divergence angle. Light that could originally be focused into a narrower area now diffuses into a wider area, leading to a decrease in the degree of light convergence and a natural expansion of the irradiated range. Simultaneously, because the light is dispersed over a larger area, this process fully complies with the law of light reflection and the converging and diverging characteristics of curved surface optics.

[0039] In one embodiment, the synchronous drive mechanism 5 includes a handle 501, a chain 502 meshing on the surface of a gear 404, a gear 503 meshing inside the chain 502, one end of the gear 503 being fixedly connected to the handle 501, and the other end of the gear 503 being fixedly connected to a synchronous wheel 504, and the handle 501 being rotatably connected inside the fixed housing 307.

[0040] By rotating the handle 501, the handle 501 drives the second gear 503 to rotate, which in turn drives the first gear 404 to rotate via the chain 502. At the same time, the second gear 503 drives the synchronous pulley 504 to rotate, thus completing the synchronous drive.

[0041] In one embodiment, the aperture mechanism 6 includes a gear ring 601 that meshes with a synchronous wheel 504. The gear ring 601 is rotatably connected inside the reflector cup 401. An aperture plate 602 is fixedly connected inside the gear ring 601. Several arc-shaped blades 603 are slidably connected to the surface of the aperture plate 602. A connecting plate 604 is fixedly connected inside the reflector cup 401. One end of each of the arc-shaped blades 603 is rotatably connected to the surface of the connecting plate 604.

[0042] The synchronous wheel 504 drives the gear ring 601 to rotate, which in turn drives the aperture plate 602 to rotate. The aperture plate 602 then drives several arc-shaped blades 603 to open and close along the surface of the connecting plate 604, thereby changing the size of the aperture formed by the middle of the several arc-shaped blades 603.

[0043] In this case, reducing the aperture further restricts the divergence of light, causing more light to concentrate in a smaller area; increasing the aperture allows more light to emerge at a wider angle, thus expanding the illumination range.

[0044] Through the above technical solution, 1. By rotating gear 404, gear 404 drives adjusting screw 403 to move axially. Adjusting screw 403 drives mounting bracket 402 to slide inside reflector cup 401, and at the same time drives light body 2 to move laterally inside reflector cup 401. When light body 2 is closer to the bottom of reflector cup 401, the light converges more strongly after being reflected by reflector cup 401, which can accurately illuminate small products and highlight product details. When light body 2 moves to the outside of reflector cup 401, the light source is away from the bottom of reflector cup 401, and the light diverges more after being reflected, which can meet the overall lighting needs of medium-sized products.

[0045] 2. By rotating the handle 501, the handle 501 drives the second gear 503 to rotate, which in turn drives the first gear 404 to rotate via the chain 502. Simultaneously, the second gear 503 drives the synchronous pulley 504 to rotate, which in turn drives the gear ring 601 to rotate. The gear ring 601 then drives the aperture plate 602 to rotate, causing the aperture plate 602 to open and close along the surface of the connecting plate 604, thus changing the size of the aperture formed by the center of the several arc-shaped blades 603. At the same time, the first gear 404 drives the adjusting screw 403 to move axially, which in turn causes the mounting bracket 402 to slide inside the reflector cup 401, and simultaneously causes the lamp body 2 to move within the reflector cup 401. The light source moves laterally to complete synchronous driving. When the light body 2 moves into the reflector cup 401, the light source is closer to the bottom of the reflector cup 401. After the light is reflected by the reflector cup 401, the convergence of the light is enhanced. At this time, the aperture shrinks synchronously. The shrinking aperture further restricts the divergence of the light, allowing more light to be concentrated in a smaller area. Under the dual effect, the focusing effect of the light is greatly improved, which can accurately illuminate small products and highlight product details. When the light body 2 moves outward from the reflector cup 401, the light source moves away from the bottom of the reflector cup 401. After the light is reflected, the divergence angle increases. At the same time, the aperture enlarges synchronously, allowing more light to be emitted at a wider angle. The illumination range is expanded accordingly, which can meet the overall lighting needs of medium-sized products.
