Description

Technical Field

[0001] This invention relates to the field of lighting devices, specifically to a tool-free light emission angle adjustment structure for lamps. Background Technology

[0002] The lighting fixtures used in factory workshops, warehouses, stadiums, large shopping malls, and other places have their light emission angles basically fixed during production. This means that the illumination range of the fixtures after installation can only be maintained within a specified area, and the light emission angles of the fixtures cannot be temporarily adjusted according to the lighting needs of the installation site.

[0003] To address the issue of adjusting the beam angle of luminaires, detachable housings have been incorporated into the fixtures for easy disassembly and adjustment of drive parameters. Alternatively, the beam angle can be adjusted by removing screws from the lens and altering its position relative to the light-emitting element. However, these methods typically require tools, and the adjustment process is cumbersome and inconvenient for luminaires already in use. Furthermore, the combination of ease of beam angle adjustment and the ability to accommodate different lighting needs in various locations is insufficient, resulting in low flexibility and limiting the luminaires' application range. Summary of the Invention

[0004] To address the technical deficiencies in the prior art, this invention proposes a tool-free light emission angle adjustment structure for lighting fixtures, solving the aforementioned technical problems and meeting practical needs. The specific technical solution is as follows: A tool-free light emission angle adjustment structure for a lamp, the tool-free light emission angle adjustment structure being distributed on the outside of the light-emitting end of the lamp and on the lamp housing, wherein a sensor is connected to the center of the end of the lamp housing near the light-emitting end via a connection port, comprising: The light source assembly includes a light source PCB and light-emitting elements. The light source PCB is fixedly connected to the middle wall of the lamp housing located outside the connection port. A plurality of light-emitting elements are disposed on the surface of the light source PCB, and the plurality of light-emitting elements are distributed in a vortex pattern on the surface of the light source PCB. A lens is disposed on the outside of the light source PCB. The surface of the lens away from the light source PCB protrudes outward to form a vortex-shaped protrusion. A mating hole is provided in the middle of the lens, and the lens is mated to the outside of the sensing end of the sensor through the mating hole. A positioning component is distributed along the edges of both the lamp housing and the lens. The positioning component includes a connecting block and protrusions. The connecting block is connected to the lamp housing via several mating grooves circumferentially provided along the edge of the lamp housing near the light source component, or it is integrally formed on the edge of the lamp housing near the light source component. The end of the connecting block near the lens has a snap-fit ​​groove with a semi-circular cross-section. Several protrusions are circumferentially provided along the edge of the lens. The included angles formed by two adjacent protrusions to the central axis of the lens are the same. The protrusions are columnar with one end having a semi-circular cross-section. The lens is connected to the connecting block through the snap-fit ​​engagement of the protrusions and the snap-fit ​​grooves. The lens is connected to or disconnected from the lamp housing via the positioning component. After the lens is disconnected from the lamp housing, the lens rotates around the central axis of the mating hole outside the light source component, changing the position of the protrusions relative to the light-emitting element, thereby adjusting the beam angle of the light-emitting end.

[0005] As a further improvement of the present invention, the fixing method of the connecting block in the mating groove includes: By connecting a fixing member into the connecting part provided at the center of both the connecting block and the mating groove, the connecting block is fixed in the mating groove; Alternatively, by means of snap-fit ​​parts provided on both sides of the connecting block and the mating groove, the connecting block can be rotated and fixed in the mating groove; Alternatively, by using a fixing part located at the edge of the connecting block, the mating groove, and the lamp housing, the connecting block can be rotated and fixed in the mating groove.

[0006] As a further improvement of the present invention, the connecting part includes a first connecting hole and a second connecting hole. The first connecting hole is located at the center of the connecting block in the direction of the lens central axis, and the second connecting hole is located on the wall surface of the lamp housing located outside the mating groove. The central axis of the first connecting hole and the central axis of the second connecting hole are on the same straight line. The connecting block is fixed in the mating groove by being inserted into the first connecting hole and the second connecting hole in sequence by a fixing member.

[0007] As a further improvement of the present invention, the snap-fit ​​part includes a first protrusion, a second protrusion, and a snap-fit ​​block. The first protrusion is provided on both sides of the connecting block. The end of the first protrusion away from the connecting block is provided with a first hemisphere. The wall surface of the lamp housing located on both sides outside the mating groove is provided with a third connecting hole. The connecting block is movably connected to the lamp housing through the first protrusion in the third connecting hole. The second protrusion is provided on the side wall of the connecting block away from the first protrusion. The snap-fit ​​block is provided on the wall surface of the lamp housing located outside the third connecting hole. The end of the snap-fit ​​block away from the third connecting hole is hook-shaped and the cross-sectional shape of the end face is arc-shaped. The connecting block rotates around the central axis of the first protrusion as the rotation center, and after the second protrusion abuts against one side of the end face of the snap-fit ​​block, it is fixed in the mating groove.

[0008] As a further improvement of the present invention, the fixing part includes a third protrusion, a fourth connecting hole, a rotating ring, and a first limiting block. The connecting block has third protrusions on both sides, and a second hemisphere is provided at the end of the third protrusion away from the connecting block. The lamp housing has fourth connecting holes on the walls outside the mating groove on both sides. The connecting block is movably connected to the lamp housing by engaging the third protrusion within the fourth connecting hole. The sidewall of the lamp housing away from the light source assembly has an external thread, and the inner wall of one end of the rotating ring has an internal thread. The rotating ring is connected by the engagement of the internal and external threads. The rotating ring is attached to the edge of the lamp housing. On the inner wall of the other end of the rotating ring, there are several first limiting blocks. The several first limiting blocks are equidistantly arranged in the circumferential direction of the rotating ring. At least two first limiting blocks face each other in the axial direction of the rotating ring and form a connection port between them. The end of the snap-fit ​​block away from the snap-fit ​​groove extends into the connection port. By moving the rotating ring in the axial direction of the lamp housing, the snap-fit ​​block rotates around the central axis of the third protrusion as the rotation center. After the snap-fit ​​groove abuts against the outer wall of the protrusion, the connecting block is fixed in the mating groove.

[0009] As a further improvement of the present invention, the end walls of the connecting block located on both sides of the snap-fit ​​groove are provided with bevels, and the surface of the bevel near the lens side is a slope whose height decreases as the distance from the snap-fit ​​groove increases.

[0010] As a further improvement of the present invention, the lens has an annular convex edge, the convex edge is integrally formed with one end of the protrusion, the inner edge of the convex edge is integrally formed with a plurality of protrusions, the surfaces on both sides of the protrusions are provided with anti-slip textures, and the lens has at least two protrusions facing the protrusion in the radial direction of the lens.

[0011] As a further improvement of the present invention, the lens edge is provided with at least two second limiting blocks, one of which is a protrusion directly opposite the protrusion, and the lens wall surface adjacent to the protrusion is provided with a second limiting block.

[0012] As a further improvement of the present invention, the inner and outer walls of the protrusion have the same shape in the axial section of the lens. The protrusion has a wavy shape in the axial section of the lens and has several protrusions. The wall thickness of the lens on the side of the protrusion away from the center of the protrusion is less than the wall thickness of the lens on the middle of the protrusion. The wall thickness of the lens on the middle of the protrusion is less than the wall thickness of the lens on the side of the protrusion close to the center of the protrusion.

[0013] As a further improvement of the present invention, it also includes an alignment component, which includes a pointing block and a dial. The lamp housing has at least two fifth connecting holes circumferentially arranged on the wall surface outside the connection port. The pointing block is arranged outside the fifth connecting hole. One end of the pointing block is provided with a sixth connecting hole. The pointing block is fixed to the wall surface outside the connection port of the lamp housing by connecting fasteners into the sixth connecting hole and the sixth connecting hole. The lens has a dial on the wall surface outside the pointing block.

[0014] The beneficial effects of this invention are as follows: Operators can release the lens from its fixed position on the light-emitting end of the lamp housing without using tools, and by rotating the lens, change the position of the protrusion on the lens outside the light-emitting element, thus altering the light path from the light-emitting element to the lens, thereby adjusting the light emission angle of the lamp. This is convenient to operate. Lamp fixtures equipped with this tool-free light emission angle adjustment structure can emit light at different angles, allowing users to select the appropriate angle during installation and use. This makes the light emission angle of the lamp more suitable for the lighting needs of the venue, enabling lamps equipped with this tool-free light emission angle adjustment structure to be used in a wider range of scenarios.

[0034] The embodiments of the present invention will now be described in conjunction with the accompanying drawings and related examples: This invention discloses a tool-free light emission angle adjustment structure for lamps, such as... Figures 1 to 16 As shown, the tool-free light emission angle adjustment structure is distributed on the outside of the light-emitting end 6 of the lamp and on the lamp housing 1 of the lamp. The center of the end of the lamp housing 1 near the light-emitting end 6 is connected to a sensor 7 via a connection port 11. The structure includes: The light source assembly 2 includes a light source PCB 21 and light-emitting elements 22. The light source PCB 21 is fixedly connected to the middle wall of the lamp housing 1 located outside the connection port 11. A plurality of light-emitting elements 22 are disposed on the surface of the light source PCB 21, and the plurality of light-emitting elements 22 are distributed in a vortex pattern on the surface of the light source PCB 21. Lens 3 is disposed on the outside of the light source PCB21. The surface of lens 3 away from the light source PCB21 protrudes outward to form a vortex-shaped protrusion 31. A mating hole 32 is provided in the middle of lens 3. Lens 3 is mated to the outside of the sensing end of sensor 7 through mating hole 32. Positioning components 4 are distributed along the edges of both the lamp housing 1 and the lens 3. The positioning components 4 include connecting blocks 41 and protrusions 42. The connecting blocks 41 are connected to the lamp housing 1 via several mating grooves 12 circumferentially arranged along the edge of the lamp housing 1 near the light source assembly 2, or are integrally formed on the edge of the lamp housing 1 near the light source assembly 2. The end of the connecting block 41 near the lens 3 has a semi-circular snap-fit ​​groove 411. Several protrusions 42 are circumferentially arranged along the edge of the lens 3. Two adjacent protrusions 42 are positioned relative to the lens 3. The included angles formed on the central axis are the same. The protrusion 42 is a columnar body with one end having a semi-circular cross-section. The lens 3 is connected to the connecting block 41 through the snap-fit ​​of the protrusion 42 and the snap-fit ​​groove 411. The lens 3 is connected to or disconnected from the lamp housing 1 through the positioning component 4. After the lens 3 is disconnected from the lamp housing 1, the lens 3 rotates outside the light source component 2 with the central axis of the mating hole 32 as the rotation center, so that the position of the protrusion 31 relative to the light-emitting element 22 changes, thereby adjusting the beam angle of the light-emitting end 6.

[0035] It should be noted that when adjusting the light emission angle of a lamp equipped with this tool-free light emission angle adjustment structure, the operator can change the connection between the lens 3 and the positioning component 4 without using tools, thereby releasing the lens 3 from its fixed position on the light-emitting end 6 of the lamp housing 1. Alternatively, by adjusting the state of the positioning component 4, the connection between the positioning component 4 and the lens 3 can be changed, similarly altering the connection between the lens 3 and the light-emitting end 6 of the lamp housing 1. This allows for the fixing and loosening of the lens 3 on the light-emitting end 6 of the lamp housing 1. The positioning component 4 consists of a connecting block 41 and a protrusion 42. The connecting block 41 in the positioning component 4 is set on the lamp housing 1 in two ways: integrally formed with the lamp housing 1 and detachably connected to the lamp housing 1. After the lens 3 is released from its fixed state, by rotating, the position of its protrusion 31, which was initially facing the light-emitting element 22, changes. The light path of the light emitted by the light-emitting element 22 towards the protrusion 31 changes within the lens 3, thereby adjusting the beam angle of the lamp. This achieves the effect of adjusting the light output angle of the lamp without tools, making the operation convenient.

[0036] Furthermore, the initial position of lens 3 relative to the light-emitting element 22, the position of lens 3 relative to the light-emitting element 22 after clockwise rotation, and the position of lens 3 relative to the light-emitting element 22 after counterclockwise rotation all correspond to different light emission angles at the corresponding light-emitting end 6. For example, if the initial light emission angle is set to 90°, the position of lens 3 is at the standard 90° light emission angle working position, the light path is centered and regular, and the light is evenly and vertically diffused, which is a conventional standard illumination mode suitable for large-area general site lighting; after rotating lens 3 counterclockwise from the initial position, lens 3 is adjusted to the 110° wide-angle position, and lens 3 emits light at a large 110° wide-angle light emission angle. This allows for ultra-wide-angle light output, significantly increasing the illumination coverage area, making it suitable for open, large-area factories, storage yards, and other similar scenarios. After rotating the lens 3 clockwise from its initial position, it adjusts to a 60° focusing angle, resulting in a concentrated beam and a longer projection distance, making it suitable for high-brightness focused lighting and long-distance fixed-point illumination scenarios. By rotating the lens 3 to different positions, the light output effect of the luminaire can be adjusted, allowing users to select the appropriate angle during actual installation and use. This ensures that the light output angle of the luminaire better matches the lighting needs of the site, enabling luminaires equipped with this tool-free light output angle adjustment structure to be used in a wider range of scenarios.

[0037] It needs to be further explained that, such as Figure 1 , Figure 2 , Figures 6 to 15 As shown, the fixing method of the connecting block 41 in the mating groove 12 includes: By connecting a fixing member into the connecting part 43 provided at the center of both the connecting block 41 and the mating groove 12, the connecting block 41 is fixed in the mating groove 12; Alternatively, by means of snap-fit ​​parts 44 provided on both sides of the connecting block 41 and the mating groove 12, the connecting block 41 can be rotated and fixed in the mating groove 12; Alternatively, by using the fixing part 45 located at the edge of the connecting block 41, the mating groove 12, and the lamp housing 1, the connecting block 41 can be rotated and fixed in the mating groove 12.

[0038] The connecting block 41 is connected to the lamp housing 1 in the mating groove 12. There are three ways to fix the connecting block 41 in the mating groove 12: First, fasteners such as screws or pins are sequentially inserted into the middle of the connecting block 41 and the wall of the lamp housing 1 outside the mating groove 12, directly fixing the connecting block 41 to the lamp housing 1. Second, the connecting block 41 is connected to the lamp housing 1 using a movable connection, and then fixed by the snap-fit ​​part 44 on the outer wall of the mating groove 12. Third, the connecting block 41 is connected to the lamp housing 1 using a movable connection, and then the fixing part 45 located on the edge of the lamp housing 1 restricts the position of the end of the connecting block 41 away from the snap-fit ​​groove 411, thereby fixing the connecting block 41. Through the various structures of the positioning components 4 described above, the means of adjusting the light emission angle of the lamp can be made more abundant and flexible without tools.

[0039] In addition, when the connecting block 41 in the positioning component 4 is integrally formed with the lamp housing 1, the operator can rotate the lens 3 counterclockwise or clockwise to move the protrusion 42 at the initial position of the lens 3 out of the locking groove 411, and while continuously rotating the lens 3, screw the protrusion 42 on the lens 3 corresponding to the light emission angle into the locking groove 411, thereby fixing the lens 3 in the corresponding light emission position, and thus realizing the operation of adjusting the light emission angle.

[0040] Specifically, such as Figure 8 and Figure 9 As shown, the connecting part 43 includes a first connecting hole 431 and a second connecting hole 432. The first connecting hole 431 is located at the center of the connecting block 41 in the direction of the central axis of the lens 3. The second connecting hole 432 is located on the wall surface of the lamp housing 1 located outside the mating groove 12. The central axis of the first connecting hole 431 and the central axis of the second connecting hole 432 are on the same straight line. The connecting block 41 is fixed in the mating groove 12 by being inserted into the first connecting hole 431 and the second connecting hole 432 in sequence by a fixing member.

[0041] In this method, fasteners such as screws and pins are sequentially inserted into the first connecting hole 431 in the middle of the connecting block 41 and the second connecting hole 432 in the outer wall of the mating groove 12 of the lamp housing 1, thereby fixing the connecting block 41 to the lamp housing 1. This method of fixing the connecting block 41 to the lamp housing 1 is relatively simple and can be achieved during the lamp manufacturing process.

[0042] Specifically, such as Figures 10 to 12As shown, the snap-fit ​​part 44 includes a first protrusion 441, a second protrusion 442, and a snap-fit ​​block 443. The connecting block 41 has first protrusions 441 on both sides, and a first hemisphere 4411 at the end of the first protrusion 441 away from the connecting block 41. The lamp housing 1 has third connecting holes 444 on both sides of the outer wall of the mating groove 12. The connecting block 41 is movably connected to the lamp housing 1 through the first protrusions 441 engaging within the third connecting holes 444. The second protrusion... 442 is disposed on the side wall of the connecting block 41 away from the first protrusion 441. The snap-fit ​​block 443 is disposed on the wall surface of the lamp housing 1 located outside the third connecting hole 444. The end of the snap-fit ​​block 443 away from the third connecting hole 444 is hook-shaped and the cross-sectional shape of the end face is arc-shaped. The connecting block 41 rotates around the central axis of the first protrusion 441 as the rotation center, and after the second protrusion 442 abuts against one side of the end face of the snap-fit ​​block 443, it is fixed in the mating groove 12.

[0043] Specifically, after the connecting block 41 rotates around the central axis of the first protrusion 441 and the second protrusion 442 abuts against one side of the end face of the locking block 443, the connecting block 41 is fixed in the mating groove 12 of the lamp housing 1. When adjusting the light emission angle of the lamp, it can be done by rotating the lens 3 counterclockwise or clockwise, or by rotating the connecting block 41 around the central axis of the first protrusion 441, causing the connecting block 41 to disengage from the second protrusion 442. The hook-shaped end of block 443 is moved out, allowing the end of connecting block 41 near the snap-fit ​​groove 411 to move away from the protrusion 42, thereby releasing the fixing effect of connecting block 41 on lens 3. Then, by rotating lens 3 counterclockwise or clockwise to the desired light output angle, connecting block 41 can be fixed back into the mating groove 12 of lamp housing 1. Using this structure to adjust the light output angle is more labor-saving than directly rotating lens 3 to move protrusion 42 out of snap-fit ​​groove 411.

[0044] Specifically, such as Figures 13 to 15As shown, the fixing part 45 includes a third protrusion 451, a fourth connecting hole 452, a rotating ring 453, and a first limiting block 454. The connecting block 41 has third protrusions 451 on both sides, and a second hemisphere 4511 at the end of the third protrusion 451 away from the connecting block 41. The lamp housing 1 has fourth connecting holes 452 on both sides of the outer wall of the mating groove 12. The connecting block 41 is movably connected to the lamp housing 1 through the third protrusions 451 engaging within the fourth connecting holes 452. The sidewall of the lamp housing 1 away from the light source assembly 2 has an external thread 455. The inner wall of one end of the rotating ring 453 has an internal thread 456. The rotating ring 453 connects with the external thread 455 through the internal thread 456. The rotating ring 453 is connected to the edge of the lamp housing 1. The inner wall of the other end of the rotating ring 453 is provided with a plurality of first limiting blocks 454. The plurality of first limiting blocks 454 are equidistantly arranged in the circumferential direction of the rotating ring 453. At least two first limiting blocks 454 are directly opposite each other in the axial direction of the rotating ring 453, and a connection port 457 is formed between them. The end of the snap-fit ​​block 443 away from the snap-fit ​​groove 411 extends into the connection port 457. By moving the rotating ring 453 in the axial direction of the lamp housing 1, the snap-fit ​​block 443 rotates around the central axis of the third protrusion 451 as the rotation center. After the snap-fit ​​groove 411 abuts against the outer wall of the protrusion 42, the connecting block 41 is fixed in the mating groove 12.

[0045] Twisting the rotating ring 453 causes it to move along the central axis of the lamp housing 1 on the outer edge of the lamp housing 1. During the movement of the rotating ring 453, the end of the connecting block 41 located in the connecting port 457 is driven by the first limiting block 454 and swings accordingly. This causes the connecting block 41 to rotate around the central axis of the third protrusion 451, causing the end of the connecting block 41 near the snap-fit ​​groove 411 to swing towards the lens 3. When the snap-fit ​​groove 411 is radially parallel to the lens 3, the position of the connecting block 41 in the mating groove 12 is fixed. Alternatively, the end of the connecting block 41 near the snap-fit ​​groove 411 can swing away from the lens 3, releasing the fixing effect of the connecting block 41 on the position of the lens 3. When adjusting the light output angle of the lamp, the position of the connecting block 41 in the mating groove 12 is kept fixed. Then, by rotating the lens 3 counterclockwise or clockwise, the protrusion 42 at the initial position of the lens 3 is adjusted. The lens 3 is moved out of the slot 411, and the protrusion 42 corresponding to the light emission angle on the lens 3 is screwed into the slot 411 while the lens 3 is continuously rotated, thereby fixing the lens 3 in the corresponding light emission position and realizing the operation of light angle adjustment. Alternatively, by turning the rotating ring 453, the end of the connecting block 41 near the slot 411 is moved away from the lens 3, releasing the fixing effect of the connecting block 41 on the lens 3. Then, the lens 3 is rotated counterclockwise or clockwise, so that the protrusion 42 corresponding to the light emission angle of the lens 3 moves to the outside of the slot 411. Then, by turning the rotating ring 453, the end of the connecting block 41 near the slot 411 is put back into the outside of the protrusion 42, thereby realizing the operation of light emission angle adjustment of the lamp. The operation of light emission angle adjustment using this structure is more labor-saving than the method of directly rotating the lens 3 to move the protrusion 42 out of the slot 411.

[0046] More specifically, such as Figure 7 , Figure 9 , Figure 12 and Figure 15 As shown, the end walls of the connecting block 41 located on both sides of the snap-fit ​​groove 411 are provided with chamfers 412. The surface of the chamfer 412 near the lens 3 is a slope 4121 whose height decreases as the distance from the snap-fit ​​groove 411 increases.

[0047] When the lens 3 rotates, the protrusion 42 on the edge of the lens 3 first contacts the inclined surface 4121 of the chamfer 412. As the lens 3 continues to rotate, the protrusion 42 slides along the inclined surface 4121 of the chamfer 412 and is gradually guided into the locking groove 411. The chamfer 412 plays a guiding and guiding role, making the installation process of the lens 3 smoother. The locking and fixing of the lens 3 can be completed without precise alignment of the locking groove 411, which improves the efficiency of the lamp's light output angle adjustment operation.

[0048] Furthermore, such as Figures 1 to 5 as well as Figure 16 As shown, the lens 3 has a ring-shaped protruding edge 33 along its edge. The protruding edge 33 is integrally formed with one end of the protrusion 42. Several protrusions 34 are integrally formed along the inner edge of the protruding edge 33. Anti-slip textures 341 are provided on the surfaces of both sides of the protrusions 34. At least two protrusions 34 of the lens 3 are directly opposite the protrusion 42 in the radial direction of the lens 3.

[0049] The protrusion 34 allows the operator to use their fingers to assist in rotating the lens 3, making it easier to guide the lens 3 to rotate and to move the protrusion 42 into or out of the locking groove 411. The anti-slip texture 341 increases the friction coefficient of the protrusion 34 surface, preventing the hand from slipping when rotating the lens 3, making the rotation of the lens 3 more convenient and effortless.

[0050] Furthermore, such as Figures 1 to 5 as well as Figure 16 As shown, the lens 3 has at least two second limiting blocks 35 along its edge, one of which is a protrusion 42 directly opposite the protrusion 34, and the lens 3 wall surface adjacent to the protrusion 42 is provided with a second limiting block 35.

[0051] Specifically, when moving from the 90° standard light output angle working position to the 110° wide-angle position, or from the 90° standard light output angle working position to the 60° focusing position, the second limiting block 35, through the setting of the second limiting block 35, after the protrusions 42 on the lens 3 corresponding to the 60° light output angle and the 110° light output angle engage with the locking groove 411 of the connecting block 41, if the lens 3 continues to rotate in the same direction, the second limiting block 35 will touch the outer wall of the connecting block 41, thereby restricting the rotation of the lens 3, ensuring that the 60° focusing position and the 110° wide-angle position can be accurately reached after rotating the lens 3.

[0052] It needs to be further explained that, such as Figures 1 to 5 , Figure 16 as well as Figure 17 As shown, the inner and outer walls of the protrusion 31 have the same shape in the axial section of the lens 3. The protrusion 31 has a wavy shape in the axial section of the lens 3 and has several protrusions 311. The wall thickness of the lens 3 on the side of the protrusion 311 away from the center of the protrusion 31 is less than the wall thickness of the lens 3 on the side of the protrusion 311 in the middle. The wall thickness of the lens 3 on the side of the protrusion 311 in the middle is less than the wall thickness of the lens 3 on the side of the protrusion 311 near the center of the protrusion 31.

[0053] When the lens 3 is positioned at the 90° standard light output angle working setting, the light-emitting element 22 is precisely located outside the center of the protrusion 311, the light path is centered and regular, and the wall thickness of the lens 3 at the center of the protrusion 311 is moderate, so that the light diffuses evenly and vertically within the lens 3. When the lens 3 is positioned at the 110° wide-angle light output angle working setting, the light-emitting element 22 is located inside the optical surface of the lens 3, and the wall thickness of the lens 3 at the inner side of the protrusion 311 is the greatest, so that the light path converges inward and then diffuses outward at a large angle within the lens 3, achieving ultra-wide-angle light output. Similarly, when the lens 3 is positioned at the 60° focusing setting, the LED lamp bead is located outside the optical surface of the lens 3, and the wall thickness of the lens 3 at the outer side of the protrusion 311 is the smallest, so that the light path is shifted outward to form a focusing effect.

[0054] It needs to be further explained that, such as Figures 1 to 6 , Figure 16 as well as Figure 18 As shown, the lamp housing 1 also includes an alignment component 5, which includes a pointing block 51 and a scale 52. The lamp housing 1 has at least two fifth connecting holes 13 circumferentially arranged on the wall outside the connection port 11. The pointing block 51 is arranged outside the fifth connecting hole 13. One end of the pointing block 51 is provided with a sixth connecting hole 511. The pointing block 51 is fixed to the wall outside the connection port 1 of the lamp housing 1 by connecting fasteners into the sixth connecting hole 511 and the sixth connecting hole 511. The lens 3 has a scale 52 arranged on the wall outside the pointing block 51.

[0055] The marker block is fixed on the outer shell of the sensor 7. During the rotation of the lens 3, the corresponding value on the scale 52 pointed to by the pointer block 51 can be observed to intuitively determine which light output angle the lens 3 is currently rotating to, thereby accurately adjusting the light output angle of the lamp.

[0056] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
