Description

Technical Field

[0001] This application relates to the field of lighting equipment technology, specifically to a lamp holder and a lamp fixture. Background Technology

[0002] Currently, conventional mercury lamps are typically secured to the lamp holder via an M8 thread at the bottom. However, this method of fixing has several problems. Due to variations in thread depth between different batches of mercury lamps, as well as wear on the nut structure, the position of the mercury lamp changes significantly after each replacement. This positional variation not only reduces the efficiency of the lighting system but also increases the difficulty of adjusting the lamp's position, making lamp replacement cumbersome and impacting the utilization rate of the mercury lamp's energy and the overall performance of the optical system. Utility Model Content

[0003] This application provides a lamp holder and lamp fixture, which adopts a clamp-type clamping design to ensure repeatability each time the mercury lamp is replaced, thereby ensuring the accuracy of the focusing position of the mercury lamp and improving the efficiency of the optical system.

[0004] In some embodiments, a lamp holder is provided, including a lamp holder body, a clamping assembly, and at least two segmented clamping members. The clamping assembly is connected to the lamp holder body and hugs the outside of each segmented clamping member. Each segmented clamping member surrounds and forms a mounting hole, and the size of the mounting hole is adjusted by the clamping assembly.

[0005] In some embodiments, the clamp assembly includes a locking member and two mating members. Each of the two mating members includes an interconnected arc-shaped mating section and an ear plate. The arc-shaped mating section matches the outer peripheral contour of the segmented clamping member. The locking member connects the ear plates of the two mating members. One of the two mating members is fixed to the lamp holder body, and the other is movably connected to the lamp holder body through the locking member.

[0006] In some embodiments, the locking member includes a screw portion and a stop portion, and the two mating members are a first mating member and a second mating member, respectively. The lug of the first mating member is rotatably engaged with the screw portion of the locking member, and the side of the first mating member away from the second mating member abuts against the stop portion. The lug of the second mating member is threadedly engaged with the screw portion of the locking member.

[0007] In some embodiments, the screw portion of the locking member includes a first threaded segment, a smooth segment, and a second threaded segment arranged sequentially along the axis of the screw portion away from the stop portion. The ear plate of the second mating member is provided with a threaded hole that matches the first threaded segment and the second threaded segment. The diameter of the smooth segment is smaller than the diameter of the threaded hole.

[0008] In some embodiments, the segmented clamping member includes a limiting portion and a clamping portion, the limiting portion being provided at least on one end face of the clamping portion, and the clamping assembly supporting the limiting portion along the axial direction of the mounting hole.

[0009] In some embodiments, the arc-shaped mating section has a plurality of protruding ridges on the side facing the segmented clamping part. Each of the protruding ridges is arranged circumferentially along the arc-shaped mating section. Each of the protruding ridges is radially movable and abuts against the opposite segmented clamping member along the mounting hole. A flow passage is formed between adjacent protruding ridges so that air can flow in the flow passage.

[0010] And / or, each of the said segmented clamping members is made of a thermally conductive material.

[0011] In some embodiments, the lamp holder body is provided with heat dissipation holes, which are adjacent to one of the mating members and arranged along the circumference of the mating member;

[0012] And / or, the lamp holder is integrally formed with one of the two mating parts.

[0013] In some embodiments, a temperature sensor is installed on the lamp holder, and the probe of the temperature sensor is adjacent to the split clamp. When the temperature detected by the temperature sensor exceeds a threshold, an alarm signal is automatically triggered.

[0014] In some embodiments, each of the segmented clamping members has a stepped structure on its inner side so that the mounting hole formed by the enclosing of each of the segmented clamping members is a stepped hole.

[0015] In some embodiments, a lamp is provided, including a mercury lamp and the lamp holder described above, wherein the mercury lamp is connected to a support member, and each of the segmented clamping members is engaged with the support member;

[0016] And / or, the support member is in the form of a stepped column.

[0017] The lamp holder provided in this embodiment allows for adjustment of the mounting hole size via a clamp assembly. This design enables the segmented clamping component to tightly hold the mercury lamp's support, ensuring the lamp's stability after installation. Furthermore, the clamping method prevents wear on the mercury lamp's support from altering its clamping position during lamp replacement, maintaining a consistent lamp position and avoiding reduced lighting efficiency and light energy utilization due to positional changes. Additionally, the segmented clamping component in this application allows for a more even distribution of force across the support's circumference. This avoids uneven localized stress that might occur when the clamping component acts directly on the support, reducing the risk of deformation or damage to the support during installation and ensuring the mercury lamp's installation accuracy and stability.

[0034] Please see Figure 1 and Figure 2 , Figure 1 These are schematic diagrams of the lamps in some embodiments of this application. Figure 2 yes Figure 1 A schematic diagram of the lamp holder structure in the embodiment.

[0035] In some embodiments, a lamp is provided, including a mercury lamp 200 and a lamp holder 100. The mercury lamp 200 is connected to a support member 201. The lamp holder 100 includes a lamp holder body 10, a clamping assembly 20, and at least two segmented clamping members 30. The clamping assembly 20 is connected to the lamp holder body 10 and fits around the outer side of each segmented clamping member 30. Each segmented clamping member 30 surrounds to form a mounting hole 33, so that the support member 201 of the mercury lamp 200 can be inserted into the mounting hole 33 and held in place by each segmented clamping member 30. The size of the mounting hole 33 can be adjusted by the clamp assembly 20. This design allows the split clamping member 30 to tightly clamp the support member 201 of the mercury lamp 200, ensuring the stability of the mercury lamp 200 after installation. Moreover, each time the mercury lamp 200 is replaced, the clamping method can prevent the support member 201 of the mercury lamp 200 from wearing out and changing the clamping position of the mercury lamp 200. This ensures that the position of the mercury lamp 200 remains consistent, avoiding the problem of reduced lighting efficiency and decreased light energy utilization caused by position changes.

[0036] Furthermore, the segmented clamping member 30 in this application allows the force of the clamping assembly 20 to be more evenly distributed circumferentially on the support member 201. The segmented clamping member 30 can disperse and bear various forces generated during the operation of the mercury lamp 200, including thermal expansion force and vibration, reducing the direct stress on the lamp holder body 10 and the clamping assembly 20. Through the synergistic effect of multiple segmented clamping members 30, the support member 201 can be clamped more stably, avoiding uneven local force that may be caused by the clamping assembly 20 acting directly on the support member 201, thereby reducing the risk of deformation or damage to the support member 201 due to uneven force during installation, and ensuring the installation accuracy and stability of the mercury lamp 200.

[0037] In this embodiment, there are two segmented clamping members 30, which are arranged symmetrically. In other embodiments, there may be three or four segmented clamping members 30, etc.

[0038] Optionally, each clamp assembly 20 can be configured with segmented clamping members 30 of different specifications, allowing the segmented clamping members 30 to be adjusted according to the shape and size of the support member 201. Because the segmented clamping members 30 can be flexibly combined and adjusted, they can better adapt to support members 201 of different specifications and shapes, improving the versatility and adaptability of the lamp holder 100. While the clamp assembly 20 adapts to the support member 201 by adjusting the size of the mounting hole 33, the presence of the segmented clamping members 30 makes this adjustment more precise and flexible, enabling more accurate clamping of the support member 201.

[0039] Please see Figure 2 and Figure 3 , Figure 3 yes Figure 2An exploded view of the lamp holder in this embodiment. In some embodiments, each segmented clamping member 30 has a stepped structure 321 on its inner side, so that the mounting hole 33 formed by the segmented clamping members 30 is a stepped hole. Correspondingly, the support member 201 is in the shape of a stepped column. Figure 3 As shown, the mounting hole 33 has a first end 331 and a second end 332. The diameter of the first end 331 is larger than the diameter of the second end 332. The first end 331 is located above the second end 332. The support member 201 can be inserted from the first end 331 of the mounting hole 33 and supported on the stepped structure 321. The stepped columnar support member 201 matches the stepped hole of the segmented clamping member 30, enabling more precise positioning and clamping, and improving the installation accuracy of the mercury lamp 200. Preventing the support member 201 from shaking or shifting within the mounting hole 33 further improves the stability of the mercury lamp 200 installation and ensures the performance of the optical system.

[0040] Please see Figure 3 In some embodiments, the clamp assembly 20 includes a locking member 21 and two mating members 22. Each mating member 22 includes an interconnected arc-shaped mating section 221 and an ear plate 222, the arc-shaped mating section 221 matching the outer periphery of the segmented clamping member 30. The locking member 21 connects the ear plates 222 of the two mating members 22; one mating member 22 is fixed to the lamp holder body 10, and the other is movably connected to the lamp holder body 10 via the locking member 21. Thus, the clamp assembly 20 can flexibly adjust the clamping force on the segmented clamping member 30, thereby indirectly adjusting the clamping force of the segmented clamping member 30 on the support member 201, ensuring that the segmented clamping member 30 will not loosen during use, thereby guaranteeing the stable installation of the mercury lamp 200.

[0041] Please see Figure 4 and Figure 5 , Figure 4 yes Figure 2 A schematic diagram illustrating the connection relationship between the locking member of the lamp holder and the ear plate in this embodiment. Figure 5 yes Figure 2 A top view of the lamp holder in the embodiment. In some embodiments, the locking member 21 includes a screw portion 211 and a stop portion 212. Two mating members 22 are a first mating member 23 and a second mating member 24, respectively. The ear plate 222 of the first mating member 23 is rotatably engaged with the screw portion 211 of the locking member 21. The side of the first mating member 23 away from the second mating member 24 abuts against the stop portion 212. The ear plate 222 of the second mating member 24 is threadedly engaged with the screw portion 211 of the locking member 21. This construction of the locking member 21 allows for precise control of the distance between the two mating members 22 by rotating the locking member 21 when adjusting the clamp assembly 20, thereby achieving the tightening or loosening of the split clamping member 30.

[0042] Please see Figure 4Furthermore, the screw portion 211 of the locking member 21 includes a first threaded section 2111, a smooth section 2112, and a second threaded section 2113 arranged sequentially along the axis of the screw portion 211 away from the stop portion 212. The ear plate 222 of the second mating member 24 is provided with a threaded hole that matches the first threaded section 2111 and the second threaded section 2113, and the diameter of the smooth section 2112 is smaller than the diameter of the threaded hole. When adjusting the clamp assembly 20, the screw portion 211 of the locking member 21 passes through the first mating member 23, and the stop portion 212 abuts against the side of the first mating member 23 away from the second mating member 24. When the screw portion 211 is screwed into the second mating member 24, the second threaded section 2113, the smooth section 2112, and the first threaded section 2111 sequentially enter the threaded hole of the second mating member 24, driving the first mating member 23 to move closer to the second mating member 24, thereby causing the clamp assembly 20 to gradually clamp the split clamping member 30. Understandably, since the diameter of the smooth section 2112 is smaller than the diameter of the threaded hole, the distance between the first mating part 23 and the second mating part 24 can be quickly adjusted in the smooth section 2112. At the same time, through the threaded engagement of the first threaded section 2111 and the second threaded section 2113 with the ear plate 222, more precise adjustment can be achieved.

[0043] In other embodiments, the locking member 21 may be a snap-fit ​​structure or other fixed connection structure connected between the first mating member 23 and the second mating member 24, which is not specifically limited here.

[0044] Please see Figure 3 In some embodiments, the segmented clamping member 30 includes a limiting portion 31 and a clamping portion 32. The limiting portion 31 is at least located on one end face of the clamping portion 32, and the clamping assembly 20 supports the limiting portion 31 axially along the mounting hole 33. Figure 3 As shown, the limiting part 31 is disposed at the upper end of the clamping part 32, and the clamping assembly 20 can be supported at the bottom of the limiting part 31, thereby preventing the segmented clamping member 30 from falling off when it is not clamped by the clamping assembly 20. Optionally, two limiting parts 31 can be provided, with the two limiting parts 31 respectively disposed at the upper and lower ends of the clamping part 32 and abutting against the opposite sides of the clamping assembly 20. This can further limit the axial movement of the segmented clamping member 30 relative to the clamping assembly 20, thereby preventing the segmented clamping member 30 from detaching from the clamping assembly 20 when it is not clamped, and ensuring that the mercury lamp 200 is stable in position after installation and will not be displaced due to external force or vibration, thus ensuring the accuracy of the focusing position of the mercury lamp 200 and improving the efficiency of the optical system.

[0045] In the aforementioned embodiment where the locking member 21 has a first threaded section 2111, a smooth section 2112, and a second threaded section 2113, the smooth section 2112 can correspond to the size of the limiting part 31. When it is necessary to loosen the clamp assembly 20, simply rotate the locking member 21 relative to the second mating member 24 until the smooth section 2112 mates with the threaded hole to quickly loosen the clamp assembly 20 and remove the mercury lamp 200. The radius of the limiting part 31 can be slightly larger than the radius of the mounting hole 33 at this time, which can prevent the split clamping member 30 from disengaging from the clamp assembly 20.

[0046] Please continue reading. Figure 3 In some embodiments, the arc-shaped mating section 221 has a plurality of protruding ribs 2212 on the side facing the segmented clamping part 32. Each protruding rib 2212 is arranged circumferentially along the arc-shaped mating section 221 and radially abuts against the opposing segmented clamping member 30 along the mounting hole 33. A flow channel is formed between adjacent protruding ribs 2212 to allow air to circulate within the flow channel. Furthermore, each segmented clamping member 30 is made of a thermally conductive material, specifically porous ceramic material, metal, alloy, etc. This heat dissipation design effectively reduces the temperature of the lamp holder 100 during use. The segmented clamping member 30 made of thermally conductive material can quickly conduct heat away, preventing the lamp holder 100 from overheating, extending the service life of the lamp holder 100, and ensuring that the mercury lamp 200 operates in a suitable temperature environment, improving its performance and lifespan.

[0047] Furthermore, the lamp holder body 10 is provided with heat dissipation holes 11, which are adjacent to one of the mating parts 22 and arranged circumferentially along the mating part 22. In addition, the lamp holder 100 is integrally formed with one of the two mating parts 22. The design of the heat dissipation holes 11 further enhances the heat dissipation capacity of the lamp holder 100, allowing heat to be dissipated to the surrounding environment more quickly by increasing the heat dissipation area. The integral forming design improves the overall structural strength and stability of the lamp holder 100.

[0048] Furthermore, a temperature sensor 40 is installed on the lamp holder 100, with the probe of the temperature sensor 40 adjacent to the split clamp 30. When the temperature detected by the temperature sensor 40 exceeds a threshold, an alarm signal is automatically triggered. This temperature monitoring function can monitor the operating temperature of the lamp holder 100 in real time. Once the temperature is too high, an alarm is immediately issued to remind the user to take appropriate measures, such as stopping the use of the lamp and checking the heat dissipation system. This not only effectively protects the lamp holder 100 and the mercury lamp 200 from damage due to overheating, but also improves the safety of lamp use and prevents safety accidents such as fires caused by overheating.
