Description

Technical Field

[0001] This utility model relates to the field of lighting equipment, and in particular to a lighting device that can be adjusted at multiple angles. Background Technology

[0002] In the field of traditional lighting equipment, multi-angle adjustment functions are usually achieved using simple mechanical structures, which have problems such as limited adjustment range, complex operation and difficulty in precise control.

[0003] Existing adjustable lighting devices mostly use single motor drive or manual adjustment, which cannot achieve simultaneous multi-directional adjustment of multiple lighting heads, resulting in poor lighting uniformity and directional control.

[0004] In addition, the lamp head angle adjustment mechanism of conventional lighting equipment usually adopts a separate design. When each lamp head is adjusted independently, it is easy to produce asynchronous phenomena, and after long-term use, the adjustment accuracy is prone to decrease due to wear of transmission components.

[0005] To address the aforementioned issues, this patent proposes a novel lighting device with a compact structure, high adjustment precision, and the ability to achieve synchronous control of multiple lamp heads, in order to meet the higher requirements of modern lighting applications for precise light control and convenient maintenance. Utility Model Content

[0006] The main purpose of this invention is to propose a lighting device that can be adjusted at multiple angles, in order to solve the problems of limited adjustment range of illumination angle and complicated operation of traditional lighting devices.

[0007] To address the aforementioned problems, this utility model proposes a multi-angle adjustable lighting device, comprising a mounting base, with external connecting frames connected to both the left and right sides of the upper end of the mounting base. A lamp holder is rotatably connected between the two external connecting frames via a rotating shaft. A transparent cover is snapped onto the upper end of the lamp holder. A front-to-back angle adjustment motor is rotatably connected to the left end of the lamp holder via a rotating shaft, and the front-to-back angle adjustment motor is connected to the upper left side of the left external connecting frame. Multiple lighting heads are arranged inside the upper end of the lamp holder, with the upper ends of the multiple lighting heads located inside the lower end of the transparent cover and arranged in two rows. A left-to-right angle adjustment component is provided between the lamp holder and the multiple lighting heads.

[0008] Preferably, each of the multiple lighting lamp heads is provided with an inner connecting frame at both the front and rear ends, and is rotatably connected to the inner connecting frame via a rotating shaft, and the lower ends of the multiple inner connecting frames are all connected to the inner wall of the lower end of the lamp holder.

[0009] Preferably, the left and right angle adjustment components include an angle adjustment groove, an angle adjustment carriage, an angle adjustment toothed rail, and an angle adjustment toothed groove. An angle adjustment groove is provided on the inner wall of the lower end of the lamp holder, and an angle adjustment carriage is engaged inside the angle adjustment groove.

[0010] Preferably, the angle-adjusting slide is slidably connected inside the angle-adjusting slide groove, and angle-adjusting toothed rails are provided on both the front and rear sides of the upper end of the angle-adjusting slide, with the two angle-adjusting toothed rails located at the lower ends of multiple lighting lamp heads in the front and rear rows, respectively.

[0011] Preferably, the lower end of the lighting head is hemispherical, and an arc-shaped adjustment groove is provided on the outer wall of the hemispherical shape. The central axis of the arc where the adjustment groove is located is coaxial with the rotation axis between the lighting head and the inner connecting frame. The adjustment groove is engaged with the upper end of the adjustment gear rail and meshes with the adjustment gear rail.

[0012] Preferably, a limiting frame is provided at the center of the inner wall of the lower end of the angle adjustment groove, and a drive gear is rotatably connected inside the limiting frame. The upper end of the drive gear is rotatably connected to a left and right angle adjustment motor via a rotating shaft.

[0013] Preferably, the left and right angle adjustment motors are connected to the upper end of the limiting frame, and the rear end of the drive gear is provided with a transmission gear and meshes with the transmission gear. The transmission gear is connected to the inner wall of the lower end of the angle adjustment slide through the limiting shaft and meshes with the front end of the rear angle adjustment gear rail.

[0014] Beneficial effects:

[0015] 1. This utility model achieves electric adjustment of the overall pitch angle of the lamp holder by means of a rotating shaft connection structure of mounting base, external connecting frame and lamp holder, and front and rear angle adjustment motor drive; at the same time, through the unique left and right angle adjustment component design, multiple lighting lamp heads can be rotated horizontally left and right at the same time to form a complete dual-degree-of-freedom adjustment system, which improves the flexibility and accuracy of lighting angle adjustment.

[0016] 2. This utility model adopts a linkage design of angle adjustment slide, angle adjustment carriage and angle adjustment gear. Through the meshing transmission of a single drive gear and transmission gear, the front and rear rows of lighting heads can achieve synchronous angle adjustment under the drive of the left and right angle adjustment motors, ensuring that multiple lamp heads turn in the same direction, avoiding the complex structure and asynchronous problem of traditional multi-lamp head independent adjustment.

[0017] 3. The angle-adjusting tooth groove of this utility model adopts an arc-shaped design that is coaxial with the lamp head shaft, so that the lamp head can maintain stable engagement with the angle-adjusting tooth rail at any rotation angle, avoiding transmission tooth slippage or jamming, and improving the reliability of the adjustment process.

[0018] 4. The transparent cover of this utility model is fixed to the upper end of the lamp holder by a snap-fit, which facilitates quick disassembly and maintenance, while not affecting the multi-directional adjustment function of the internal lamp head, thus taking into account both protection performance and maintenance convenience.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To achieve the above-mentioned utility model objectives, such as Figures 1-5As shown, this utility model provides a multi-angle adjustable lighting device, including a mounting base 1. External connecting frames 2 are connected to the left and right sides of the upper end of the mounting base 1. A lamp holder 3 is rotatably connected between the two external connecting frames 2 via a rotating shaft. A transparent cover 4 is snapped onto the upper end of the lamp holder 3. A front-to-back angle adjustment motor 5 is rotatably connected to the left end of the lamp holder 3 via a rotating shaft, and the front-to-back angle adjustment motor 5 is connected to the upper left side of the left external connecting frame 2. Multiple lighting heads 6 are arranged inside the upper end of the lamp holder 3, with the upper ends of the multiple lighting heads 6 located inside the lower end of the transparent cover 4, arranged in two rows. A left-to-right angle adjustment component is provided between the lamp holder 3 and the multiple lighting heads 6. The lighting device is fixed by the mounting base 1 and provides illumination through the multiple lighting heads 6. The multiple lighting heads 6 can adjust their front-to-back illumination angle by rotating the lamp holder 3, and can also adjust their left-to-right illumination angle through the left-to-right angle adjustment component. The lamp holder 3 can be driven to rotate by the front-to-back angle adjustment motor 5, thereby adjusting the front-to-back angle of the lamp holder 3 and thus adjusting the front-to-back illumination angle of the multiple lighting heads 6.

[0029] Preferably, each of the multiple lighting lamp heads 6 has an inner connecting frame 7 at both the front and rear ends, and is rotatably connected to the inner connecting frame 7 via a rotating shaft. The lower ends of the multiple inner connecting frames 7 are all connected to the inner wall of the lower end of the lamp holder 3. The multiple lighting lamp heads 6 can adjust the left and right illumination angle by rotating between the two inner connecting frames 7 on both sides.

[0030] Preferably, the left and right angle adjustment assembly includes an angle adjustment groove 8, an angle adjustment carriage 9, an angle adjustment toothed rail 10, and an angle adjustment toothed groove 11. An angle adjustment groove 8 is provided on the inner wall of the lower end of the lamp holder 3. The angle adjustment carriage 9 is engaged inside the angle adjustment groove 8 and slidably connected inside the angle adjustment groove 8. An angle adjustment toothed rails 10 are provided on both the front and rear sides of the upper end of the angle adjustment carriage 9, and the two angle adjustment toothed rails 10 are respectively located at the lower ends of multiple lighting heads 6 in the front and rear rows. The lower end of the lighting head 6 is hemispherical, and an arc-shaped angle adjustment toothed groove 11 is provided on the outer wall of the hemisphere. The central axis of the arc where the angle adjustment toothed groove 11 is located is the pivot between the lighting head 6 and the inner connecting frame 7. The coaxial angle adjustment groove 11 is engaged with the upper outer side of the angle adjustment gear 10. During the adjustment of the left and right illumination angle of multiple lighting heads 6, since the angle adjustment slide 9 is slidably connected inside the angle adjustment groove 8, and the upper end of the angle adjustment gear 10 is engaged with the angle adjustment groove 11, when the angle adjustment slide 9 slides left and right inside the angle adjustment groove 8, the angle adjustment slide 9 drives the two upper angle adjustment gears 10 to move left and right, and drives the multiple lighting heads 6 to rotate through the angle adjustment groove 11, thereby synchronously adjusting the left and right illumination angle of the multiple lighting heads 6.

[0031] Since the central axis of the arc where the angle adjustment groove 11 is located is coaxial with the rotating shaft between the lighting head 6 and the inner connecting frame 7, the angle adjustment groove 11 can always be engaged with the upper end of the angle adjustment gear 10 during the rotation of the lighting head 6, thus ensuring stable transmission.

[0032] Preferably, a limiting frame 12 is provided at the center of the lower inner wall of the angle adjustment slide 8. A drive gear 13 is rotatably connected inside the limiting frame 12. The upper end of the drive gear 13 is rotatably connected to a left and right angle adjustment motor 14 via a rotating shaft. The left and right angle adjustment motor 14 is connected to the upper end of the limiting frame 12. A transmission gear 15 is provided at the rear end of the drive gear 13 and meshes with it. The transmission gear 15 is connected to the lower inner wall of the angle adjustment slide 8 via a limiting shaft and meshes with the front end of the rear angle adjustment gear rail 10. During the left and right sliding of the angle adjustment slide 9... The left and right angle adjustment motor 14 is connected to the inner wall of the lower end of the angle adjustment slide 8 through the limiting frame 12, and drives the drive gear 13 to rotate. The drive gear 13 drives the transmission gear 15 to rotate. Since the drive gear 13 and the rear angle adjustment gear 10 are provided with the transmission gear 15 and are meshed with the transmission gear 15, the drive gear 13 can drive the angle adjustment gear 10 to move left and right through the transmission gear 15, thereby driving the angle adjustment slide 9 to slide left and right inside the angle adjustment slide 8, thereby realizing the adjustment of the left and right illumination angle of multiple lighting lamp heads 6.

[0033] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
