Description

Technical Field

[0001] This application relates to the field of optical instrument technology, and in particular to a xenon lamp. Background Technology

[0002] Xenon lamps are electric light sources that generate intense light through the discharge of high-pressure xenon gas. They are characterized by high brightness, a color temperature close to sunlight, and a wide spectral range, playing an important role in many fields. For example, xenon lamps are commonly used as the detection light source in testing equipment such as ellipsometers. Due to their high brightness, xenon lamps have a relatively short lifespan, requiring frequent bulb replacements.

[0003] A xenon lamp is disclosed in the related technology, including a housing, a light source assembly inside the housing, and a fixing member for fixing the light source assembly. The light source assembly includes a bulb and a heat sink fitted on the bulb. The housing is provided with screws for locking the fixing member. The fixing member is rotatably connected to the housing. The fixing member can be rotated by simply unscrewing the screws, opening the housing from one side and exposing the bulb, thereby allowing the bulb to be replaced.

[0004] However, after the bulb is replaced, the light path emitted by the xenon lamp may not be in the preset center position due to the different bulb types, wattages, and light-emitting point positions. As a result, it is difficult to accurately illuminate the item to be tested when used as a detection light source, and the detection effect is poor. Utility Model Content

[0005] This application provides a xenon lamp fixture to solve the problem that the optical path position may be inaccurate after replacing a xenon lamp.

[0006] A xenon lamp fixture, comprising:

[0007] The main body of the lamp chamber includes a base plate and an outer shell, wherein the base plate and the outer shell are fixed and the interior is hollow;

[0008] A xenon lamp assembly is mounted on the base plate and covered by the housing, and the xenon lamp assembly is capable of emitting light toward the outside of the housing;

[0009] An adjustment member is provided at one end of the base plate along the length direction and is partially located outside the housing. The adjustment member extends into the housing and is connected to the xenon lamp assembly. The adjustment member can control the xenon lamp assembly to move along the length direction and the height direction.

[0010] By adopting the above technical solution, the adjustment component can directly control the movement of the xenon lamp assembly along the length and height directions. When the lamp chamber is installed on the polarization arm of the ellipsometer or connected to the ellipsometer and other equipment through optical fiber, and after changing different bulbs, it can accurately calibrate the xenon lamp light to the center position of the optical path and keep it parallel, ensuring the accuracy and repeatability of optical measurements (such as thin film thickness detection by the ellipsometer), and the operation is simple.

[0011] In one embodiment, the adjusting member includes an abutment shell, a movable block, a first movable member, and a second movable member. The abutment shell is disposed outside the outer shell. One end of the movable block abuts against the abutment shell along its length, and the other end extends into the outer shell and is connected to the xenon lamp assembly. The first movable member passes through the abutment shell and the movable block along its length and is connected to the xenon lamp assembly. The first movable member is capable of moving the xenon lamp assembly along its length. The second movable member passes through the abutment shell along its height and is disposed on the movable block. The second movable member is capable of moving the movable block, the xenon lamp assembly, and the first movable member along its height.

[0012] By adopting the above technical solution, the first moving component controls the movement in the length direction, and the second moving component controls the movement in the height direction. The two operate independently, avoiding the coupling error of traditional single-axis adjustment. For example, in an ellipsometer, the first moving component can be used to adjust the axial alignment of the xenon lamp and the optical fiber, and then the second moving component can be used to fine-tune the height, so that the light is precisely coupled to the end face of the optical fiber.

[0013] In one embodiment, the abutment shell is provided with a through hole that extends in the height direction, and the first movable member is capable of moving in the height direction within the through hole.

[0014] By adopting the above technical solution, the through hole limits the height movement range of the first moving part, preventing the xenon lamp assembly from excessively rising and falling during the adjustment of the second moving part, which could lead to collision with the inner wall of the housing or the light path exceeding the receiving range of the device. The first moving part slides in the through hole, which is equivalent to adding a guide structure, making the height adjustment smoother and avoiding a decrease in adjustment accuracy due to shaking.

[0015] In one embodiment, the adjustment member further includes a limiting block disposed on the side of the xenon lamp assembly away from the movable block and fixed to the movable block.

[0016] By adopting the above technical solution, the limiting block can limit the length movement distance of the xenon lamp assembly, preventing the xenon lamp from being misaligned with the front panel (light outlet) of the housing due to excessive adjustment of the first moving part, which would make it difficult for the light to be emitted or cause the electrode leads to be pulled and broken.

[0017] In one embodiment, the adjusting member further includes a first guide post that extends along its length, one end of which is disposed on the moving block, and the other end passes through the xenon lamp assembly and is fixed to the limiting block.

[0018] By adopting the above technical solution, the first guide post penetrates the xenon lamp assembly and the limiting block, providing rigid support for movement in the length direction and preventing the xenon lamp assembly from swaying during sliding (e.g., sway angle < 0.5°), thus ensuring stable light direction. When the second moving component drives the moving block to rise and fall, the first guide post simultaneously drives the xenon lamp assembly and the limiting block to move, avoiding misalignment due to uneven force, ensuring that the length-direction limiting function and height adjustment are effective simultaneously, and improving overall adjustment efficiency.

[0019] In one embodiment, the xenon lamp assembly includes a base and a xenon lamp. The base is disposed between the movable block and the limiting block and is penetrated by the first guide post and the first movable member. The xenon lamp is disposed along the height direction and its lower end is rotatably connected to the base.

[0020] By adopting the above technical solution, the xenon lamp is located on the upper part of the base and is rotatably connected, which facilitates the replacement of different xenon lamps. At the same time, the adjustment component makes it easy to adjust the light to be in the center position according to the illumination of different xenon lamps.

[0021] In one embodiment, the xenon lamp assembly further includes a heat sink disposed at the upper end of the xenon lamp, and the upper surface of the housing is provided with a heat dissipation channel.

[0022] By adopting the above technical solution, the heat sink directly contacts the upper end of the xenon lamp, and together with the heat dissipation channel at the upper end of the casing, a natural convection heat dissipation system is formed.

[0023] In one embodiment, the housing includes a front plate and a rear plate disposed on both sides of the xenon lamp assembly along the width direction, the front plate having a light outlet, and the xenon lamp assembly being able to emit light toward the light outlet.

[0024] By adopting the above technical solution, the diameter of the light outlet of the front panel is matched with the light emission aperture of the xenon lamp. Combined with the adjustment function of the adjustment component, the beam divergence angle is controlled within ±1.5°, so that the light can still be emitted through the light outlet after the xenon lamp is adjusted in position, which is suitable for applications that require collimated light.

[0025] In one embodiment, the rear plate is provided with a set screw and a reflector. The set screw is located on the outer surface of the rear plate, and the reflector is located on the inner wall surface of the rear plate. The set screw is connected to the reflector.

[0026] By adopting the above technical solution, the tilt angle of the reflector can be adjusted by the set screw (with an accuracy of ±0.05°), and the direct light and reflected light of the xenon lamp can be precisely combined to form a superimposed light spot or a dual-light path system. After adding a small hole tooling outside the lamp chamber, it is convenient to image.

[0027] In one embodiment, the housing is further provided with a trigger and a power interface, the power interface being electrically connected to the trigger and an external power supply, and the trigger being connected to both ends of the xenon lamp along the height direction.

[0028] By adopting the above technical solution, the trigger and xenon lamp are connected at both ends along the height direction, shortening the high-voltage pulse transmission path, reducing energy loss, lowering the trigger voltage, and extending the trigger's lifespan. Simultaneously, only one power cord is needed to connect to the trigger, resulting in a lighter overall lamp housing weight, not exceeding 2.5 kg.

[0029] In summary, this application includes at least one beneficial effect:

[0030] 1. The adjustment component can directly control the movement of the xenon lamp assembly along the length and height directions. When the lamp chamber is installed on the polarization arm of the ellipsometer or connected to the ellipsometer and other equipment through optical fiber, or when different bulbs are replaced, it can accurately calibrate the xenon lamp light to the center position of the optical path and keep it parallel, ensuring the accuracy and repeatability of optical measurements (such as thin film thickness detection by the ellipsometer). The operation is simple and does not require moving the entire lamp, making it more convenient.

[0031] 2. The first guide post penetrates the xenon lamp assembly and the limiting block, providing rigid support for movement along the length direction and preventing the xenon lamp assembly from swaying during sliding (e.g., sway angle < 0.5°), ensuring stable light direction. When the second moving component moves the moving block up and down, the first guide post simultaneously moves the xenon lamp assembly and the limiting block, avoiding misalignment due to uneven force, ensuring that the length-direction limiting function and height adjustment are effective simultaneously, and improving overall adjustment efficiency.

[0032] 3. By adjusting the tilt angle of the reflector with the set screw (accuracy up to ±0.05°), the direct light and reflected light from the xenon lamp can be precisely combined to form a superimposed light spot or a dual-light path system. This facilitates imaging after adding a small hole fixture externally. Attached Figure Description

[0041] The following is in conjunction with the appendix Figure 1-7 The xenon lamp fixture provided in this application will be described in further detail.

[0042] Example 1

[0043] Please see Figure 1-7 The xenon lamp fixture provided in this application embodiment includes a lamp chamber body 1, a xenon lamp assembly 2, and an adjustment component 3.

[0044] like Figures 1 to 3As shown, the lamp chamber body 1 includes a base plate 11 and an outer shell 12, which are fixed together and hollow inside. The xenon lamp assembly 2 is mounted on the base plate 11 and covered by the outer shell 12, emitting light towards the outside of the outer shell 12. Specifically, the base plate 11 is usually made of a metal material with certain strength and stability, such as aluminum alloy, and its shape can be rectangular, providing stable support for the xenon lamp assembly 2. The outer shell 12 can be made of stainless steel or other materials, serving to protect the xenon lamp assembly 2 and prevent damage from external dust, moisture, etc. The base plate 11 and the outer shell 12 can be fixed together by means of bolts or other disassembly connections, forming an internal space. In this embodiment, the outer shell 12 includes a front plate 121 and a rear plate 122 located on both sides of the xenon lamp assembly 2 along its width direction. The front plate 121 has a light outlet 1211, towards which the xenon lamp assembly 2 can emit horizontal light. The size and shape of the light outlet 1211 are designed according to actual needs to ensure that the light can be emitted smoothly. The outer casing 12 also includes a left side plate 123 and a right side plate 124 at both ends along its length. Both the left side plate 123 and the right side plate 124 are L-shaped and detachably fixed to the base plate 11. The upper surface of the outer casing 12 is formed by splicing the left side plate 123 and the right side plate 124. The left side plate 123, the right side plate 124, together with the front plate 121 and the rear plate 122, cover the xenon lamp assembly 2, which is located below the left side plate 123. The upper surfaces of the left side plate 123 and the right side plate 124 may be provided with heat dissipation channels 125. The heat dissipation channels 125 can be strip-shaped holes or a mesh structure, which facilitates the dissipation of heat within the lamp chamber, reduces the temperature within the lamp chamber, and ensures the normal operation of the xenon lamp assembly 2.

[0045] The xenon lamp assembly 2 includes a base 21 and a xenon lamp 22. The base 21 is generally a block structure with certain strength and stability, and its material can be insulating. The xenon lamp 22 extends along the height direction and is rotatably fixed to the base 21 with one end pointing downwards. Both ends of the xenon lamp 22 are made of metal. A copper block 211 can be provided inside the base 21. The lower end of the xenon lamp 22 extends into the copper block 211. The right side plate 124 of the housing is provided with a trigger 126 and a power interface 127. The power interface 127 is electrically connected to an external power source and the trigger 126. The trigger 126 extends into the base 21 through a wire and communicates with the copper block 211, and then with the lower end of the xenon lamp 22. At the same time, it is connected to the upper end of the xenon lamp 22 through another wire. The trigger 126 can provide high voltage to the xenon lamp 22, thereby igniting the xenon lamp 22.

[0046] The xenon lamp assembly 2 also includes a heat sink 23, which is located at the upper end of the xenon lamp 22. The heat sink 23 is generally made of metal, such as aluminum alloy, and has good heat dissipation performance. The heat sink 23 can be in various shapes, such as sheet-like or needle-like, to increase the contact area with air and improve heat dissipation efficiency. The heat sink 23 is in direct contact with the xenon lamp 22, thus absorbing the heat from the xenon lamp 22 and dissipating heat to prevent damage to the xenon lamp 22 due to overheating. The heat sink 23 is fixed to the upper end of the xenon lamp 22 by screws 24. When the xenon lamp 22 needs to be replaced, first remove the left side panel 123, then loosen the thumbscrews on the heat sink 23 and remove the heat sink 23. Then, rotate the xenon lamp 22 out of the base 21 to replace it with a new xenon lamp 22.

[0047] like Figures 4 to 5 As shown, the adjustment component 3 is located at one end of the base plate 11 along the length direction and partly outside the housing 12, and partly extends into the housing 12 to connect with the xenon lamp assembly 2. It can control the xenon lamp assembly 2 to move along the length and height directions, so that the position of the xenon lamp assembly 2 can be precisely adjusted so that the light emitted by the xenon lamp 22 is in the center of the optical path, which improves the accuracy and stability of the light and reduces the impact of light deviation on the measurement accuracy of the equipment.

[0048] Specifically, the adjusting component 3 includes an abutment shell 31, a movable block 32, a first movable component 33, and a second movable component 34. The abutment shell 31 is disposed outside the left side plate 123 of the outer casing 12. The base plate 11 extends beyond the left side plate 123, allowing the abutment shell 31 to be fixed to the base plate 11 and abut against the left side plate 123, thus providing support and positioning for other components. The abutment shell 31 can be made of metal, which has good strength and stability, or it can be made of high-strength plastic to reduce the overall weight. The movable block 32 is L-shaped, with one end abutting against the abutment shell 31 along its length, and the other end extending into the outer casing 12 and fixed to the base 21. The movable block 32 has a smooth surface, facilitating sliding within the abutment shell 31 and the outer casing 12. The first moving part 33 passes through the abutment shell 31 and the moving block 32 along the length direction and is connected to the base 21. The first moving part 33 can move along the length direction with the xenon lamp assembly 2. The second moving part 34 passes through the abutment shell 31 along the height direction and is located on the moving block 32. The second moving part 34 can move along the height direction with the moving block 32, the xenon lamp assembly 2 and the first moving part 33.

[0049] The abutment shell 31 may be provided with a through hole 311, which extends along the height direction, allowing the first moving member 33 to move along the height direction within the through hole 311. The function of the through hole 311 is to limit the range of movement of the first moving member 33 in the height direction, ensuring the accuracy and stability of the movement and ensuring that the light from the xenon lamp 22 is mainly emitted from the light outlet 1211. The inner wall of the through hole 311 is smooth to reduce the frictional force during the movement of the first moving member 33.

[0050] The adjusting component 3 also includes a limiting block 35, which is located on the side of the xenon lamp assembly 2 away from the moving block 32. The limiting block 35 is generally a block-shaped structure and can be made of rubber for cushioning; it can also be made of metal to ensure reliable limiting. The function of the limiting block 35 is to limit the distance the xenon lamp assembly 2 moves along its length, preventing excessive movement and damage. In this embodiment, the distance between the limiting block 35 and the moving block 32 can be 5mm.

[0051] The adjusting component 3 may further include a first guide post 36, which extends along the length direction. One end of the first guide post 36 is disposed on the moving block 32, and the other end passes through the base 21 and is fixed to the limiting block 35. In this embodiment, two first guide posts 36 are provided and are disposed on both sides of the first moving component 33 along the width direction. The first guide post 36 may be cylindrical with a smooth surface or a square column. The function of the first guide post 36 is to ensure that when the first moving component 33 slides along the length direction with the xenon lamp assembly 2, the xenon lamp assembly 2 can slide smoothly along the first guide post 36 and will not deviate from the direction; in addition, when the second moving component 34 moves the moving block 32 along the height direction, it moves the xenon lamp assembly 2 and the limiting block 35 together through the first guide post 36. Meanwhile, the adjusting component 3 may also include a second guide post 37. The second guide post 37 is provided on the base plate 11 and extends through the moving block 32 along the height direction. There are two second guide posts 37 located on both sides of the second moving component 34 along the width direction. The second guide post 37 can also prevent the moving block 32 from moving along the length direction and ensure that the moving block 32 slides smoothly along the height direction without deviating from the direction and affecting the position of the light.

[0052] like Figures 6 to 7As shown, in this embodiment, the first moving part 33 includes a first screw 331 and a first nut 332. The first screw 331 passes through the abutment shell 31 and the moving block 32 and is connected to the base 21. There are two first nuts 332, which are reversed to fix the first screw 331. One first nut 332 is located in the base 21, and the other first nut 332 is located between the first screw 331 and the abutment shell 31. When it is necessary to control the xenon lamp 22 to move along the length direction, the first nut 332 near the abutment shell 31 is loosened, and then the first screw 331 is rotated. Since the moving block 32 abuts against the abutment shell 31, the first screw 331 can only control the movement of the base 21. At the same time, the rotation and movement can realize the fine adjustment of the light position with high precision. Similarly, the second moving part 34 includes a second screw 341 and two reverse-fixed second nuts 342. One second nut 342 is located on the abutment shell 31, and the other second nut 342 is located inside the moving block 32. When the xenon lamp 22 needs to move along the height direction, the second nut 342 located on the abutment shell 31 is loosened, and then the second screw 341 is rotated, so that the second screw 341 controls the movement of the moving block 32, the first screw 331, the base 21, and the limiting block 35. When the light is observed to be in the appropriate position, the nut is tightened, thereby realizing the precise adjustment of the xenon lamp 22 in the length and height directions without loosening multiple bolts, making the operation simpler. This xenon lamp can be directly installed on the polarization arm of an ellipsometer, or the light can be introduced into the ellipsometer or other equipment through an optical fiber, thereby serving as a detection light to detect information about objects.

[0053] The rear plate 122 may also be equipped with a set screw 1221 and a reflector 1222. The set screw 1221 is located on the outer surface of the rear plate 122, and the reflector 1222 is located on the inner wall of the rear plate 122. The set screw 1221 is connected to the reflector 1222 and corresponds to the xenon lamp 22 along its width. By rotating the set screw 1221, pushing or pulling one side of the reflector 1222 can change the tilt angle of the reflector 1222, thereby adjusting the direction of the reflected light. This allows the light emitted by the xenon lamp 22 to converge with the light reflected by the reflector at the small hole after a small hole fixture is installed outside the lamp, thus forming an image. The reflector 1222 is generally a spherical mirror with high reflectivity, which can effectively focus light onto the lamp.

[0054] The implementation principle of this embodiment is as follows: Through a reasonable structural design, especially the setting of the adjustment component 3, the xenon lamp fixture achieves precise adjustment of the xenon lamp assembly 2 in the length and height directions. This allows for flexible changes in the position of the xenon lamp 22, ensuring that the emitted light hits the center of the entire optical path and remains parallel to the platform on the biasing arm, improving the accuracy and stability of the light and facilitating subsequent inspection. Simultaneously, the placement of the heat sink 23 and the heat dissipation channel 125 effectively reduces the heat generated by the xenon lamp 22 during operation, extending its service life. Furthermore, the cooperation of the reflector 1222 and the set screw 1221 allows for adjustment of the direction of the reflected light, facilitating the convergence of the light emitted by the xenon lamp 22 and the light reflected by the reflector during pinhole imaging, thus improving light utilization. These designs improve upon the problem of potentially inaccurate xenon lamp path positioning in existing technologies, are easy to operate, and meet the stringent requirements of modern optical inspection equipment for light source accuracy and stability, demonstrating high practicality and innovation.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
