Description

Technical Field

[0001] This application relates to the field of lighting technology, and in particular to a bulb optical center adjustment system and a lighting fixture. Background Technology

[0002] To ensure the performance indicators of the lamps, such as brightness and color temperature, it is necessary to replace bulbs that have reached the end of their service life. Since the optical center of a new bulb is often not on the optical axis set by the lamp after it is installed, and the deviation of each bulb is different, it is necessary to adjust the optical center of each bulb after installation so that the optical center of the bulb coincides with the optical axis set by the lamp to achieve the expected light effect.

[0003] In related technologies, an eccentric screw is typically installed along the optical axis of the luminaire. The eccentric screw is rotated about a center parallel to the optical axis while observing the light spot until the bulb's optical center is aligned with the center of the light spot, thus adjusting the bulb's optical center. To improve the ease of adjustment, a hole is usually made in the heat sink at the rear of the lamp body. A screwdriver is inserted through the heat sink into the lamp body to control the rotation of the eccentric screw. However, for luminaires with high waterproofing requirements, it is inconvenient to make a hole in the heat sink. Therefore, for these types of luminaires, the heat sink at the rear of the lamp body needs to be removed to expose the eccentric screw, providing sufficient operating space for adjusting the optical center.

[0004] However, when the bulb's optical center is not adjusted, the luminaire itself remains balanced. But after the heat sink at the rear of the luminaire is removed, the luminaire loses its balance and swings. The light spot wobbles with the swing of the luminaire, which not only affects the control and adjustment of the eccentric screw, but also affects the observation and judgment of whether the bulb's optical center is properly adjusted. This makes the adjustment of the bulb's optical center troublesome and affects work efficiency. Utility Model Content

[0041] After replacing a light bulb, a misalignment often occurs between the bulb's optical center and the luminaire's optical axis. Since the misalignment varies from bulb to bulb, the optical center of each bulb must be adjusted individually after replacement to align with the luminaire's designed optical axis, thus achieving the desired luminous efficacy. Related technologies, such as... Figure 1As shown, in order to adjust the optical center of the bulb 10, an eccentric screw 300 is usually set along the optical axis of the lamp. By rotating the eccentric screw 300 with the direction parallel to the optical axis as the center, while observing the light spot, the optical center of the bulb 10 is adjusted to the center of the light spot, so that the optical center of the bulb 10 coincides with the optical axis. At the same time, in order to improve the convenience of optical center adjustment, a hole is usually made in the heat sink 202 at the rear of the lamp body. A screwdriver is inserted into the lamp body through the heat sink 202 to control the rotation of the eccentric screw 300. However, for lamps with high waterproof requirements (such as waterproof bubble lamps), the waterproof requirements make it inconvenient to make a hole in the heat sink 202. Therefore, it is necessary to remove the heat sink 202 at the rear of the lamp body to expose the eccentric screw 300 to meet the operating space for adjusting the optical center. However, when the light center of bulb 10 is not adjusted, the luminaire itself remains balanced. But after removing the heat sink 202 at the rear of the lamp body, the luminaire loses its balance and wobbles. The light spot sways with the luminaire's wobbling, which not only affects the control and adjustment of the eccentric screw 300, but also affects the observation and judgment of whether the light center of bulb 10 is properly adjusted. This makes the adjustment of the light center of bulb 10 cumbersome and affects work efficiency. In addition, after the heat sink 202 is removed, the heat generated by bulb 10 cannot be dissipated in time, which deteriorates the heat dissipation conditions of bulb 10 and affects its heat dissipation effect. When the adjustment of the light center of bulb 10 takes too long, bulb 10 may be damaged due to insufficient heat dissipation, affecting the lifespan of bulb 10.

[0042] Based on this, this application provides a bulb optical center adjustment system 100. By setting an adjustment module 40 movably connected to a movable bracket 30, the adjustment module 40 rotates or moves in a direction perpendicular to the optical axis to drive the movable bracket 30 to move relative to the fixed bracket 20 in a direction perpendicular to the optical axis, thereby adjusting the position of the bulb optical center relative to the optical axis. This solves the problems of cumbersome operation and low work efficiency in adjusting the bulb optical center, as well as the problem of affecting the lifespan of the bulb 10 due to adjusting the optical center.

[0043] This application discloses a bulb optical center adjustment system 100, which can be applied to a lamp 200 to adjust the optical center of the bulb 10 to coincide with the optical axis set by the lamp 200, thereby achieving the expected luminous effect.

[0044] To facilitate understanding of the structure of the bulb optical center adjustment system 100 and the luminaire 200, the bulb optical center adjustment system 100 and the luminaire 200 will be further described below in conjunction with embodiments and accompanying drawings. It should be noted that the following description is merely illustrative and not a specific limitation of this application.

[0045] Please refer to the following: Figures 2 to 3This application provides a lamp 200, including a bulb optical center adjustment system 100. The lamp 200 has an optical axis, and the bulb optical center adjustment system 100 is used to adjust the optical center of the bulb so that the optical center coincides with the optical axis. Please refer to... Figures 2 to 7 Specifically, the bulb optical center adjustment system 100 includes a bulb 10, a fixed bracket 20, a movable bracket 30, and an adjustment module 40. The bulb 10 is mounted on the movable bracket 30. The movable bracket 30 and the fixed bracket 20 are spaced apart along the optical axis. The movable bracket 30 can move relative to the fixed bracket 20. The adjustment module 40 is movably connected to the movable bracket 30. The adjustment module 40 is used to rotate or move in a direction perpendicular to the optical axis to drive the movable bracket 30 to move relative to the fixed bracket 20 in a direction perpendicular to the optical axis.

[0046] The bulb optical center adjustment system 100 and lamp 200 provided in this application embodiment are configured with an adjustment module 40 movably connected to a movable bracket 30. The adjustment module 40 is rotated or moved in a direction perpendicular to the optical axis of the lamp 200, thereby driving the movable bracket 30 to move relative to the fixed bracket 20 in a direction perpendicular to the optical axis. This causes the optical center of the bulb 10 to move relative to the optical axis set by the lamp 200, thereby adjusting the optical center of the bulb 10 and ensuring the luminous efficiency of the lamp 200. Furthermore, since the movement direction of the adjustment module 40 is perpendicular to the optical axis, there is no need to drill a hole in the heat sink 202 installed at the rear of the lamp 200 for a screwdriver to pass through, which helps to ensure the waterproof performance of the lamp 200. At the same time, there is no need to remove the heat sink 202 to obtain operating space. This allows the lamp 200 to maintain balance during the adjustment of the light center of the bulb 10, which is beneficial to the adjustment of the light center of the bulb 10, improves the convenience of the light center adjustment of the bulb 10, and thus improves work efficiency. On the other hand, it also ensures the operational reliability of the heat sink 202 during the light center adjustment, ensuring the heat dissipation effect of the heat sink 202 on the bulb 10, and thus ensuring the safety and service life of the bulb 10.

[0047] In some embodiments, the luminaire 200 further includes a housing 201, a cover, and a heat sink 202. The heat sink 202 is installed in the housing 201. The housing 201 has a mounting cavity and a first opening 201a communicating with the mounting cavity. The direction of the first opening 201a is perpendicular to the optical axis. The bulb optical center adjustment system 100 is installed in the mounting cavity and the fixing bracket 20 is fixedly connected to the housing 201. The cover is movably connected to the housing 201 to cover or open the first opening 201a. The adjustment module 40 is located at the end of the movable bracket 30 near the first opening 201a.

[0048] In this way, by adjusting the movement of the cover relative to the housing 201, the first opening 201a is opened. At this time, the operator can adjust the adjustment module 40 through the first opening 201a, so that the adjustment module 40 rotates or moves in a direction perpendicular to the optical axis, thereby driving the movable bracket 30 to move the bulb 10 relative to the fixed bracket 20. This makes the adjustment of the light center of the bulb 10 more convenient. Simply opening the cover allows for easy operation of the adjustment module 40, which helps to improve the ease of operation of the light center adjustment and improve work efficiency. At the same time, since the cover is relatively light, the impact on the center of gravity of the lamp 200 is small when the cover moves relative to the housing 201, which helps to ensure that the lamp 200 maintains a balanced state, so as to facilitate the adjustment of the light center of the bulb 10. Furthermore, the heat sink 202 is always installed on the housing 201, so that the heat sink 202 can always remain in working condition during the adjustment of the light center of the bulb 10, ensuring the heat dissipation effect of the bulb 10, which helps to ensure the safety and service life of the bulb 10. When the optical center of the bulb 10 is adjusted to coincide with the optical axis of the lamp 200, the cover is adjusted to seal the first opening 201a, so that the lamp 200 remains waterproof and sealed, thereby improving the operational reliability of the lamp 200.

[0049] Optionally, the connection between the cover and the housing 201 can be any of the following: threaded connection, hinged connection, or snap-fit ​​connection. The specific connection can be set according to actual needs and is not limited here, but it must meet the waterproof performance and structural stability of the lamp 200.

[0050] In some embodiments, the fixed bracket 20 includes a fixed bracket body 21, and the movable bracket 30 includes a movable bracket body 31 and a first movable plate 32. The movable bracket body 31 and the fixed bracket body 21 are spaced apart along the optical axis. The bulb 10 is installed on the side of the movable bracket body 31 away from the fixed bracket body 21. The first movable plate 32 is connected to the end of the movable bracket body 31 near the first opening 201a and extends along the optical axis. The adjustment module 40 is movably connected to the first movable plate 32. This benefits both by reducing the thickness of the movable bracket body 31, making it thinner and lighter, thus facilitating its movement and reducing the weight of the lamp 200, and by increasing the area on the movable bracket 30 that allows it to connect with the adjustment module 40, thereby improving the connection between the adjustment module 40 and the movable bracket 30 and enhancing the structural reliability of the bulb optical center adjustment system 100.

[0051] Optionally, the adjustment module 40 includes a first threaded fastener 41 and a first axial limiting component 42. The first axial limiting component 42 is used to limit the axial displacement of the first threaded fastener 41. The first movable plate 32 is provided with a first threaded hole 321. The first threaded fastener 41 is threadedly connected to the first threaded hole 321. The axial direction of the first threaded fastener 41 and the center line direction of the first threaded hole 321 are both perpendicular to the optical axis direction.

[0052] In this way, by limiting the axial displacement of the first threaded fastener 41 by the first axial limiting component 42, when the first threaded fastener 41 rotates, the first movable plate 32 moves along the axial direction of the first threaded fastener 41 under the cooperation of the first threaded hole 321 and the first threaded fastener 41, thereby driving the movable frame body 31 to move in the direction perpendicular to the optical axis. At this time, the bulb 10 moves relative to the optical axis of the lamp 200, so as to realize the adjustment of the optical center of the bulb 10. The adjustment module 40 and the movable bracket 30 are connected by threads, which is conducive to controlling the displacement of the movable bracket 30, thereby improving the accuracy of the optical center adjustment of the bulb 10.

[0053] Understandably, in other embodiments, the adjustment module 40 and the movable bracket 30 may also be fixedly connected, and the adjustment of the bulb's optical center can be achieved by pushing the adjustment module 40 to control the movement of the movable bracket 30.

[0054] Optionally, the first axial limiting component 42 includes a first fixing ring 421, a first baffle 422, and a second baffle 423. The first baffle 422 and the second baffle 423 are spaced apart and respectively connected to the fixing bracket 20. The first baffle 422 is provided with a first movable hole 4221, and the second baffle 423 is provided with a second movable hole 4231. The first fixing ring 421 is sleeved on the outer periphery of the first threaded fastener 41 and is located between the first baffle 422 and the second baffle 423. The first threaded fastener 41 is sequentially provided through the first movable hole 4221, the second movable hole 4231, and the first threaded hole 321.

[0055] In this way, the first fixing ring 421 is clamped by the first baffle 422 and the second baffle 423 to achieve axial positioning of the first threaded fastener 41, so as to ensure that the first threaded fastener 41 can drive the first movable plate 32 to move along the axial direction of the first threaded fastener 41 when rotating, so as to adjust the position of the light center of the bulb 10 relative to the optical axis.

[0056] Optionally, the first threaded fastener 41 includes a first adjusting screw 411 and a first adjusting head 412 connected to one end of the first adjusting screw 411. The first adjusting screw 411 passes sequentially through a first movable hole 4221, a second movable hole 4231, and a first threaded hole 321, and is threadedly connected to the first threaded hole 321. The first adjusting head 412 is located at the end of the first adjusting screw 411 away from the first threaded hole 321, and is used to abut against the side of the first baffle 422 away from the second baffle 423. This facilitates both axial positioning of the first threaded fastener 41 and allows the operator to control the rotation of the first threaded fastener 41, so as to adjust the axial movement of the first movable plate 32 along the first threaded fastener 41.

[0057] Optionally, the first baffle 422 and the second baffle 423 can be connected as a whole by a connecting plate to facilitate the assembly of the adjustment module 40.

[0058] In some embodiments, the adjustment module 40 further includes a second threaded fastener 43 and a second axial limiting component 44. The second threaded fastener 43 is connected to the second axial limiting component 44, and the second axial limiting component 44 is used to limit the axial displacement of the second threaded fastener 43. The movable bracket 30 also includes a second movable plate 33. The second movable plate 33 is connected to the end of the movable bracket body 31 near the first opening 201a and is spaced apart from the first movable plate 32. The second movable plate 33 extends along the optical axis direction and is provided with a second threaded hole. The centerline direction of the second threaded hole is perpendicular to the centerline direction of the first threaded hole 321 and the optical axis direction. The second threaded fastener 43 is threadedly connected to the second threaded hole.

[0059] In this way, by setting the second threaded fastener 43, the second axial limiting component 44 and the second movable plate 33, the second threaded fastener 43 can drive the movable frame body 31 to move along an axis perpendicular to the first threaded fastener 41, so that the movable frame body 31 can move relative to the fixed bracket 20 in two mutually perpendicular directions under the drive of the first threaded fastener 41 and the second threaded fastener 43 respectively. This improves the flexibility of the position adjustment of the movable frame body 31, which is conducive to making the optical center of the bulb 10 coincide with the optical axis, so as to ensure the luminous efficiency of the lamp 200 after the bulb 10 is replaced. Furthermore, the centerline direction of the second threaded hole is perpendicular to the centerline direction of the first threaded hole 321, which enables the movable bracket 30 to be displaced in a single direction. This ensures that when the movable bracket 30 is adjusted in one of the centerline directions of the first threaded hole 321 and the second threaded hole, the movable bracket 30 will not be displaced in the other direction. By superimposing multiple single-direction displacement adjustments, the optical center of the bulb 10 reaches the target position, thus ensuring the structural reliability of the bulb optical center adjustment system 100 and improving the flexibility and reliability of the adjustment module 40 in adjusting the optical center of the bulb 10.

[0060] Understandably, in some other embodiments, the centerline direction of the first threaded hole 321 and the centerline direction of the second threaded hole may form an acute or obtuse angle. However, with such a design, when the movable support 30 is adjusted along one of the centerline directions of the first threaded hole 321 and the second threaded hole, the movable support 30 may get stuck in the other direction, causing the operation of adjusting the light center of the bulb 10 to be unsmooth or stuck, affecting the convenience of operation.

[0061] Optionally, the fixed bracket 20 further includes a first fixed plate 22 and a second fixed plate 23. The first fixed plate 22 and the second fixed plate 23 are respectively connected to the main body 21 of the fixed bracket and extend along the optical axis. The first fixed plate 22 is provided with a first clearance groove 221, which extends along the direction parallel to the center line of the second threaded hole. The second fixed plate 23 is provided with a second clearance groove, which extends along the direction parallel to the center line of the first threaded hole 321. The first baffle 422 and the second baffle 423 are respectively installed on both sides of the first fixed plate 22, and the first fixed ring 421 is located in the first clearance groove 221. The first fixed ring 421 can move along the extension direction of the first clearance groove 221. The second threaded fastener 43 passes through the second clearance groove and can move along the extension direction of the second clearance groove.

[0062] Thus, when the first threaded fastener 41 drives the first movable plate 32 to move along the axial direction of the first threaded fastener 41, the second threaded fastener 43 can move within the second clearance groove under the drive of the second movable plate 33, so as to realize the displacement of the movable bracket 30 relative to the fixed bracket 20 along the axial direction of the first threaded fastener 41. When the second threaded fastener 43 drives the second movable plate 33 to move along the axial direction of the second threaded fastener 43, the first threaded fastener 41 can move within the first clearance groove 221 under the drive of the first movable plate 32, so as to realize the displacement of the movable bracket 30 relative to the fixed bracket 20 along the axial direction of the second threaded fastener 43. In this way, while ensuring the stability of the fixed bracket 20, the adjustment module 40 can drive the movable bracket 30 to move relative to the fixed bracket 20 in two mutually perpendicular directions, so as to realize the adjustment of the position of the light center of the bulb 10 relative to the optical axis in two directions, thereby improving the flexibility of the bulb light center adjustment system 100. Meanwhile, by setting the first baffle 422 and the second baffle 423 to be installed on both sides of the first fixed plate 22 respectively, the first threaded fastener 41 is sequentially inserted into the first movable hole 4221, the first clearance groove 221, the second movable hole 4231 and the first threaded hole 321. This facilitates the adjustment of the distance between the first baffle 422 and the second baffle 423 according to the size of the first fixed ring 421, so as to improve the flexibility of movement of the first fixed ring 421 along the extension direction of the first clearance groove 221.

[0063] Understandably, in some other embodiments, the first baffle 422 and the second baffle 423 may be directly connected to the movable frame body 31 without the need for the first fixed plate 22 and the second fixed plate 23. When either the first threaded fastener 41 or the second threaded fastener 43 is adjusting the movable bracket 30, the other one is disconnected from the movable bracket 30. That is, after the adjustment module 40 adjusts the position of the movable bracket 30 relative to the fixed bracket 20 in one direction, the adjustment module 40 is switched to adjust the position of the movable bracket 30 in another direction. Alternatively, the adjustment module 40 may only be used to control the movement of the movable bracket 30 in a single direction.

[0064] Optionally, the first clearance groove 221 and the second clearance groove have openings, and the openings are located at the ends of the first fixing plate 22 and the second fixing plate 23 away from the fixing frame body 21, thereby facilitating the installation and movement of the first threaded fastener 41 and the second threaded fastener 43.

[0065] Optionally, the first baffle 422 and the second baffle 423 are threadedly connected to both sides of the first fixed plate 22, which facilitates the adjustment of the distance between the first baffle 422 and the second baffle 423, so as to facilitate the movement of the first fixed ring 421 in the first relief groove 221, and to facilitate the adaptation of first fixed rings 421 of different thicknesses.

[0066] Understandably, in other embodiments, the first baffle 422 and the second baffle 423 may also be connected to the first fixing plate 22 by means of snap-fit ​​connection, welding or bonding.

[0067] In some embodiments, the second axial limiting component 44 includes a second fixing ring, a third baffle 441, and a fourth baffle 442. The third baffle 441 and the fourth baffle 442 are respectively installed on both sides of the second fixing plate 23. The third baffle 441 is provided with a third movable hole, and the fourth baffle 442 is provided with a fourth movable hole. The second fixing ring is sleeved on the outer periphery of the second threaded fastener 43 and located in the second relief groove. The second fixing ring can move along the extension direction of the second relief groove, and the second threaded fastener 43 is sequentially provided through the third movable hole, the second relief groove, the fourth movable hole, and the second threaded hole.

[0068] The second fixing ring is clamped by the third baffle 441 and the fourth baffle 442 to achieve axial fixation of the second threaded fastener 43, so as to ensure that the second threaded fastener 43 can drive the second movable plate 33 to move along the axial direction of the second threaded fastener 43 when rotating, so as to adjust the position of the light center of the bulb 10 relative to the optical axis.

[0069] Optionally, the third baffle 441 and the fourth baffle 442 are threadedly connected to both sides of the second fixed plate 23, which facilitates the adjustment of the distance between the third baffle 441 and the fourth baffle 442, so as to facilitate the movement of the second fixed ring in the second clearance groove, and to facilitate the adaptation of second fixed rings of different thicknesses.

[0070] Understandably, in other embodiments, the third baffle 441 and the fourth baffle 442 may also be connected to the second fixing plate 23 by means of snap-fit ​​connection, welding or bonding.

[0071] Optionally, the second threaded fastener 43 includes a second adjusting screw and a second adjusting head connected to one end of the second adjusting screw. The second adjusting screw passes sequentially through the third movable hole, the second clearance groove, the fourth movable hole, and the second threaded hole, and is threadedly connected to the second threaded hole. The second adjusting head is located at the end of the second adjusting screw away from the second threaded hole, and is used to abut against the side of the third baffle 441 away from the fourth baffle 442. This facilitates both axial positioning of the second threaded fastener 43 and allows the operator to control the rotation of the second threaded fastener 43 to adjust the axial movement of the second movable plate 33 along the second threaded fastener 43.

[0072] Optionally, the inner diameters of the first movable hole 4221 and the second movable hole 4231 are larger than the outer diameter of the first adjusting screw 411, and the inner diameters of the third movable hole and the fourth movable hole are larger than the outer diameter of the second adjusting screw, to facilitate the rotation of the first adjusting screw 411 and the second adjusting screw in a direction perpendicular to the optical axis. That is, the first adjusting screw 411 and the second adjusting screw can rotate around their own axis and can also move along the extension direction of the first clearance groove 221 and the second clearance groove, but cannot be displaced along their own axial direction. This ensures that the rotation of the first adjusting screw 411 is converted into the axial displacement of the first movable plate 32 along the first adjusting screw 411, and the rotation of the second adjusting screw is converted into the axial displacement of the second movable plate 33 along the second adjusting screw, so as to realize the movement of the movable bracket 30 in a direction perpendicular to the optical axis.

[0073] Optionally, considering that the first baffle 422 is located between the first adjusting head 412 and the first fixing ring 421, and the third baffle 441 is located between the second adjusting head and the second fixing ring bracket, the first movable hole 4221 of the first baffle 422 and the third movable hole of the third baffle 441 are both provided with mounting openings 4222. The mounting openings 4222 extend to the edge of the plate along the optical axis, which facilitates the assembly and disassembly of the first baffle 422 and the third baffle 441. This allows the first adjusting screw 411 to enter the first movable hole 4221 through the mounting opening 4222, and the second adjusting screw to enter the third movable hole through the mounting opening 4222, so as to realize the assembly of the first threaded fastener 41 and the first axial limiting component 42, and the assembly of the second threaded fastener 43 and the second axial limiting component 44, thereby facilitating the assembly and disassembly of the adjusting module 40.

[0074] Please combine Figure 2 , Figure 4 as well as Figure 8 In some embodiments, the bulb optical center adjustment system 100 further includes a locking module 50, which is movably connected to one end of the movable bracket 30 near the adjustment module 40. The locking module 50 is used to fasten the movable bracket 30 to the fixed bracket 20 so that the movable bracket 30 is fixed relative to the fixed bracket 20.

[0075] In this way, on the one hand, after the optical center of the bulb 10 is adjusted, the movable bracket 30 can be fixedly connected to the fixed bracket 20 through the locking module 50 to control the movement of the movable bracket 30 relative to the fixed bracket 20, so that the bulb 10 remains fixed within the lamp 200, ensuring the reliability of the lamp 200 and avoiding the situation where the optical center of the bulb 10 changes relative to the optical axis again due to shaking or collision. On the other hand, by setting the locking module 50 at the end of the movable bracket 30 near the adjustment module 40, the locking module 50 can also be positioned near the first opening 201a of the movable bracket 30, which is beneficial for the operator to adjust the locking module 50 and improve work efficiency.

[0076] Optionally, the locking module 50 includes a locking washer 51, a locking screw 52, ​​and a locking nut 53. The locking washer 51 is disposed on the side of the movable frame body 31 away from the fixed frame body 21. The fixed frame body 21 is provided with a first fixing hole, and the movable frame body 31 is provided with a second fixing hole 311. The locking screw 52 is movably inserted through the first fixing hole, the second fixing hole 311, and the locking washer 51 in sequence. One end of the locking screw 52 is provided with a first limiting part 54, which is used to abut against the side of the fixed frame body 21 away from the movable frame body 31. The locking nut 53 is threadedly connected to the locking screw 52 and abuts against the side of the locking washer 51 away from the movable frame body 31.

[0077] In this way, the movement of the locking washer 51 and the fixed frame body 21 is controlled by the locking nut 53 and the first limiting part 54. The locking washer 51 and the fixed frame body 21 clamp and fix the movable frame body 31, so that the movable bracket 30 and the fixed bracket 20 are relatively fixed, ensuring the stability of the bulb 10 within the lamp 200, ensuring that the optical center of the bulb 10 and the optical axis remain aligned after the bulb 10 is replaced, and improving the luminous efficiency of the lamp 200. When it is necessary to adjust the optical center of the bulb 10, the locking nut 53 is loosened, allowing the movable frame body 31 to move relative to the fixed frame body 21 to meet the adjustment of the optical center of the bulb 10.

[0078] Optionally, the first fixing hole can be a hole with a diameter that varies along the center line direction, such as a stepped hole or an oblique hole. The shape of the first fixing hole is adapted to the shape of the first limiting part 54 so that the first limiting part 54 can be hidden in the first fixing hole. This helps to reduce the thickness of the bulb optical center adjustment system 100 along the optical axis direction, which is beneficial to the miniaturization design of the lamp 200. It also helps to prevent the first limiting part 54 from contacting other components inside the lamp 200 and affecting the operation of the lamp 200.

[0079] Optionally, the inner diameter of the second fixing hole 311 is larger than the outer diameter of the locking screw 52, ​​and the size of the locking washer 51 is larger than the inner diameter of the second fixing hole 311. This is to facilitate the movement of the movable frame body 31 relative to the locking screw 52 when the locking nut 53 is loosened. This ensures that the movable frame body 31 is limited along the optical axis while allowing the movable frame body 31 to move relative to the fixed frame body 21 in the direction perpendicular to the optical axis, thereby ensuring the operational reliability of the bulb optical center adjustment system 100.

[0080] Optionally, there can be multiple locking modules 50, and multiple first fixing holes and multiple second fixing holes 311. Each locking module 50 corresponds to a different first fixing hole and a different second fixing hole 311. The multiple locking modules 50 are distributed at intervals on the movable frame body 31 to improve the overall stability of the movable frame body 31 relative to the fixed frame body 21 along the optical axis and improve the structural reliability of the lamp 200.

[0081] Please combine Figure 2 , Figure 4 as well as Figure 9 In some embodiments, considering that the locking module 50 is installed at the end of the lamp 200 near the first opening 201a, when the lamp 200 rotates to the point where the movable bracket 30 is below the fixed bracket 20, the movable bracket 30 tends to separate from the fixed bracket 20. The end of the movable bracket 30 away from the locking module 50 may droop or bend under the action of gravity in the direction away from the fixed bracket 20. Based on this, the bulb optical center adjustment system 100 also includes a limiting module 60. The limiting module 60 includes a limiting pad 61. The movable bracket 30 is movably disposed between the limiting pad 61 and the fixed frame body 21 of the fixed bracket 20. The limiting pad 61 is used together with the fixed frame body 21 to restrict the movement of the movable bracket 30 along the optical axis.

[0082] This design helps maintain the distance between the movable bracket 30 and the fixed bracket 20, ensuring the structural reliability of the bulb optical center adjustment system 100. Furthermore, it allows the movable bracket body 31 to move closely against the surface of the fixed bracket body 21 when translating along a direction perpendicular to the optical axis, reducing the positional change of the bulb 10 in the optical axis direction and ensuring the luminous efficacy of the lamp 200. Simultaneously, it improves the relative stability of the movable bracket 30 and the fixed bracket 20 during the transportation of the bulb optical center adjustment system 100 and the lamp 200, preventing significant shaking and impact between the movable bracket 30 and the fixed bracket 20.

[0083] Optionally, the limiting module 60 also includes a support member 62, a limiting screw 63, and a limiting nut 64. The fixed frame body 21 of the fixed bracket 20 is provided with a first through hole, the movable frame body 31 of the movable bracket 30 is provided with a second through hole 312, and the limiting gasket 61 is provided with a third through hole. The limiting screw 63 is sequentially inserted through the first through hole, the second through hole 312, and the third through hole along the optical axis. The support member 62 is sleeved on the outer periphery of the limiting screw 63 and partially located in the second through hole 312. One side of the support member 62 abuts against the fixed frame body 21, and the other side of the support member 62 abuts against the limiting gasket 61. One end of the limiting screw 63 is provided with a second limiting part 65, which is used to abut against the side of the fixed frame body 21 away from the movable frame body 31. The limiting nut 64 is threadedly connected to the limiting screw 63 and abuts against the side of the limiting gasket 61 away from the movable frame body 31.

[0084] In this way, by controlling the distance between the limiting pad 61 and the fixed bracket 20 through the support member 62, it is beneficial to ensure the flexibility of movement of the movable frame body 31 relative to the fixed frame body 21 while limiting the displacement of the movable frame body 31 along the optical axis. At the same time, by clamping the limiting pad 61 and the movable frame body 31 through the second limiting part 65 and the limiting nut 64, the structural stability of the limiting module 60 can be ensured, the limiting effect of the movable frame body 31 along the optical axis can be ensured, and it is also beneficial to adjust the frictional force of the relative movement of the movable frame body 31 and the fixed frame body 21 to control the flexibility of movement of the movable frame body 31 relative to the fixed frame body 21. Moreover, it is also beneficial to disassemble and assemble the limiting module 60 to facilitate structural maintenance and replacement of parts.

[0085] Optionally, the first through hole can be a hole with a diameter that varies along the centerline direction, such as a stepped hole or an oblique hole. The shape of the first through hole is adapted to the shape of the second limiting part 65 so that the second limiting part 65 can be hidden in the first through hole. This helps to reduce the thickness of the bulb optical center adjustment system 100 along the optical axis, which is beneficial for the miniaturization design of the lamp 200. It also helps to prevent the second limiting part 65 from contacting other components inside the lamp 200 and affecting the operation of the lamp 200.

[0086] Optionally, the inner diameter of the second through hole 312 is larger than the outer diameter of the support member 62, and the size of the limiting pad 61 is larger than the inner diameter of the second through hole 312, so as to ensure the structural reliability of the movement of the movable frame body 31 relative to the limiting module 60. While ensuring the limiting of the movable frame body 31 along the optical axis, it also satisfies the movement of the movable frame body 31 relative to the fixed frame body 21 in the direction perpendicular to the optical axis, so as to ensure the operational reliability of the bulb optical center adjustment system 100.

[0087] Optionally, there can be multiple limiting modules 60, and multiple first through holes and multiple second through holes 312. The multiple limiting modules 60 correspond one-to-one with the multiple first through holes and multiple second through holes 312. The multiple limiting modules 60 are distributed at intervals on the movable frame body 31, which helps to control the overall stability of the movable frame body 31 relative to the fixed frame body 21 along the optical axis and improve the axial limiting effect on the movable frame body 31.

[0088] For example, the movable frame body 31 is rectangular in shape, and there are four limiting modules 60. The four limiting modules 60 are respectively located near the four corners or near the four edges of the movable frame body 31.

[0089] Optionally, the first screw head, the second screw head, the first limiting part 54, and the second limiting part 65 are each provided with any one of a slotted groove, a cross groove, or a star groove. The specific type can be adapted to the shape of the screwdriver tool, and there is no limitation here.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
