[0041] Please also refer to Figures 1 to 8 The adjustable beam angle lamp provided by the present invention is now described. The adjustable beam angle lamp includes a main body 10, a rotating rod 20, a lens plate 30, a light source plate 40, and a light transmission plate 50. The rotating rod 20 is rotatably connected to the main body 10, with one end of the rotating rod 20 extending out of the main body 10; the lens plate 30 is in transmission engagement with the rotating rod 20; the light source plate 40 is fixedly connected to the main body 10 and is located behind the lens plate 30; the light transmission plate 50 is fixedly connected to the main body 10 and is located in front of the lens plate 30;

[0042] The rotation of the rotating rod 20 drives the lens plate 30 to move in a direction perpendicular to the axial direction of the rotating rod 20 to adjust the overlap between the spherical portion 31 on the lens plate 30 and the lamp beads 41 on the light source plate 40 .

[0043] It should be noted that the lens plate 30 is provided with an array of spherical parts 31, and the light source plate 40 is provided with an array of lamp beads 41. Under normal circumstances, each spherical part 31 corresponds to a lamp bead 41. When the lens plate 30 moves, the position of the spherical part 31 relative to the lamp bead 41 changes, that is, the degree of overlap between the spherical part 31 and the lamp bead 41 changes, thereby causing a change in the beam angle.

[0044] Compared to the prior art, the adjustable beam angle lamp provided in this embodiment allows for adjustment of the beam angle during use by rotating the rotating rod 20. The rotating rod 20 drives the lens plate 30 to move along an axial position perpendicular to the rotating rod 20. The resulting movement changes the degree of overlap between the spherical portion 31 on the lens plate 30 and the lamp beads 41 on the light source plate 40, thereby adjusting the beam angle. This utility model provides an adjustable beam angle lamp that is convenient to use. Users can adjust the lens plate 30 by rotating the rotating rod 20 at any time during use, meeting various usage scenarios and enhancing the user experience.

[0045] In some embodiments, an improved embodiment of the rotating rod 20 can be as follows: Figures 4 to 6 The structure shown. Figures 4 to 6 The rotating rod 20 is provided with a plurality of weight-reducing grooves 21. The weight-reducing grooves 21 on the rotating rod 20 can reduce the weight of the rotating rod 20, thereby saving effort when manually rotating the rotating rod 20 and reducing labor intensity. In addition, the weight-reducing grooves 21 on the rotating rod 20 can also reduce the material used for the rotating rod 20, thereby reducing manufacturing costs.

[0046] In some embodiments, an improved embodiment of the rotating rod 20 can be as follows: Figure 3 and Figure 6 The structure shown. Figure 3 and Figure 6 The end of the rotating rod 20 is fixed with a knob 22, which is rotatably engaged with the side wall of the main body 10. By providing the knob 22 at the end of the rotating rod 20, manual operation is more convenient and the use is more flexible, wherein the knob 22 can be rotated by hand or with a tool.

[0047] In some embodiments, an improved embodiment of the knob 22 may be as follows: Figure 3 The structure shown. Figure 3 A screw groove 23 and a pointer are provided on the side of the knob 22 facing the outside, and a scale mark corresponding to the pointer is provided on the outer periphery of the main body 10 corresponding to the knob 22.

[0048] The knob 22 in this embodiment can be flush with the outer wall of the main body 10, thereby avoiding accidental touching of the knob 22 to cause changes in the beam angle during normal use. When the beam angle needs to be adjusted, a tool can be inserted into the groove of the knob 22 to drive the rotating rod 20 to rotate. During the rotation process, the movement of the lens plate 30 can be judged by observing the position of the pointer pointing to the scale mark, which increases the adjustment accuracy of the lens plate 30.

[0049] In some embodiments, an improved embodiment of the above-mentioned lamp with adjustable beam angle can be adopted as follows Figure 5 The structure shown. Figure 5 The knob 22 is provided with a serrated strip 3224 extending along its circumference on one side facing the inside of the main body 10. A pressing piece 11 is also provided inside the main body 10. The pressing piece 11 has first teeth 12 that cooperate with the serrated strip 3224. The first teeth 12 change their position on the serrated strip 3224 as the knob 22 rotates. The pressing piece 11 is fixed to the main body 10. When the knob 22 rotates, the pressing piece 11 remains stationary. When the knob 22 rotates, a "clicking" sound is emitted due to the cooperation between the first teeth 12 and the serrated strip 3224, making it easier to judge the internal cooperation relationship and enhancing the user experience.

[0050] In some embodiments, a specific matching relationship between the rotating rod 20 and the lens plate 30 can be as follows: Figure 4 and Figure 6 The structure shown. Figure 4 and Figure 6 The rotating rod 20 is provided with two rotating disks 25. Each rotating disk 25 has a second toothed portion 26 on its outer periphery. A rack 32 is provided on the rear side of the lens plate 30 to engage with the second toothed portion 26. When the rotating rod 20 rotates, the second toothed portion 26 on the rotating disk 25 engages with the rack 32 to move the lens plate 30. This engagement process is more responsive and improves the stability of the movement of the lens plate 30.

[0051] It should be noted that the second teeth 26 may be provided in only one section of the outer circumference of the turntable 25 or in a full circle, as long as the movement stroke of the lens plate 30 is satisfied.

[0052] In some embodiments, an improved embodiment of the lens plate 30 may be as follows: Figure 4 and Figure 6 The structure shown. Figure 4 and Figure 6 A boss 13 is provided in the main body 10, and the light source board 40 is fixed to the front side of the boss 13. A baffle 33 is protruding from the rear part of the lens board 30 close to the rotating rod 20, and the rack 32 is provided on the rear side of the baffle 33. The baffle 33 is used to abut against the side wall of the boss 13 when the lens board 30 moves to a preset position.

[0053] The boss 13 not only facilitates the installation of the light source board 40 and the lens board 30, but also abuts against the baffle 33 of the lens board 30 when the lens board 30 moves to the extreme position, preventing the lens board 30 from continuing to move, avoiding the lens board 30 from moving too far, and playing a limiting role for the lens board 30.

[0054] In some embodiments, a modified embodiment of the rotating rod 20 and the lens plate 30 may be as follows: Figure 7 The structure shown. Figure 7 Two pulleys 27 are provided on the rotating rod 20, and two rollers 14 are provided within the main body 10. One pulley 27 and one roller 14 form a transmission group, and each transmission group is fitted with a conveyor belt 28, which is fixedly connected to the rear side of the lens plate 30. One pulley 27 and one roller 14 form a transmission group, and the other pulley 27 and the other roller 14 form a transmission group. When the rotating rod 20 rotates, the conveyor belt 28 follows and drives the lens plate 30 back and forth. This structure is relatively low-cost, but the movement of the lens plate 30 is relatively unstable.

[0055] In some embodiments, an improved embodiment of the lens plate 30 may be as follows: Figure 4 and Figure 6 The structure shown. Figure 4 and Figure 6 The main body 10 is provided with a slot 15 extending perpendicularly to the axis of the rotating rod 20. The light source board 40 is provided with a through-hole corresponding to the slot 15. A protrusion 34 is provided on the rear side of the lens board 30. The protrusion 34 extends through the through-hole and slidably engages with the slot 15. The length of the slot 15 is the movable length of the lens board 30. When the lens board 30 moves under the drive of the rotating rod 20, the protrusion 34 moves with the lens board 30 within the slot 15, providing guidance. This ensures that the lens board 30 does not deviate during movement, thereby preventing the light transmission of the light source board 40 from being affected.

[0056] In some embodiments, an improved embodiment of the main body 10 can be adopted as follows Figure 4 The structure shown. Figure 4 The main body 10 is provided with a plurality of support ribs 16, each of which is provided with a support groove, into which the rotating rod 20 rotates. To improve the stability of the rotating rod 20, the plurality of support ribs 16 are evenly distributed along the axial direction of the rotating rod 20. The provision of the support ribs 16 provides support for the outer periphery of the rotating rod 20, preventing the rotating rod 20 from bending or deformation, thereby extending its service life.

[0057] It is easy to imagine that the supporting groove is semicircular in shape in order to fit the outer circumference of the rotating rod 20 .

[0058] It should be noted that when the rotating rod 20 is provided with a rotating disk 25, the diameter of the rotating disk 25 is larger than the diameter of the supporting groove, and the multiple support ribs 16 are located between the two rotating disks 25. The relationship between the rotating disk 25 and the support ribs 16 prevents the rotating rod 20 from moving in the axial direction. Similarly, when the rotating rod 20 is provided with a pulley 27, the diameter of the pulley 27 is larger than the diameter of the supporting groove, and the multiple support ribs 16 are located between the two pulleys 27.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
