Detailed Implementation

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0048] In the description of this application, it should be noted that relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. The term "connection" should be interpreted broadly, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0049] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0050] As described in the background section, in existing measurement light boxes, the bulb and lamp holder are fixedly connected by screws, and the position of the lamp holder is also fixed. This makes it difficult for operators to control the bulb's position when changing it, easily leading to drastic fluctuations in light intensity and errors in the position of the replaced bulb, ultimately resulting in inaccurate measurement results. Therefore, how to reduce the measurement error caused by bulb replacement is a technical problem that urgently needs to be solved by those skilled in the art.

[0051] To resolve the above technical issues, please refer to Figure 1 This application provides a measurement light box 10, which includes: a box body 100, a T-shaped support 200, an XY axis adjustment module 300, and a lamp holder 400.

[0052] The lamp holder 400 is located inside the housing 100, and the bottom of the lamp holder 400 is plugged into the bulb.

[0053] The top of the housing 100 has a first through hole 110. The vertical part of the T-shaped support 200 passes through the first through hole 110 and is connected to the top of the lamp holder 400. The horizontal part of the T-shaped support 200 covers the first through hole 110 and contacts the outer surface of the top of the housing 100.

[0054] The side wall of the housing 100 is provided with a second through hole 120. One end of the XY axis adjustment module 300 passes through the second through hole 120 and is connected to the side wall of the lamp holder 400. The other end of the XY axis adjustment module 300 is located outside the housing 100, and the other end of the XY axis adjustment module 300 is used to adjust the position of the lamp holder 400 so as to drive the bulb to move.

[0055] Based on the above design, when the bulb in the measuring light box 10 needs to be replaced, firstly, remove several screws from the front cover of the box 100 to expose the internal structure of the box 100. Then, remove the old bulb from the bottom of the lamp holder 400 and insert the new bulb. Next, re-secure the front cover with several screws to form a sealed box 100. Finally, adjust the position of the lamp holder 400 using the XY axis adjustment module 300 to move the bulb along the X and Y axes until the light intensity and position of the newly installed bulb meet the requirements.

[0056] Compared to existing technologies that use screws to fix the bulb and lamp holder, this application sets the bulb and lamp holder 400 to a plug-in connection, which enables quick replacement of the bulb in the small internal space of the housing 100, avoids drastic fluctuations in light intensity, and reduces the difficulty and risk of error in the replacement operation.

[0057] Compared to existing technologies that fix the lamp holder in a fixed position, this application, by opening a first through hole 110 at the top of the housing 100 and connecting it to a T-shaped support 200, not only suspends the lamp holder 400 inside the housing 100, ensuring its fixed position in the Z-axis direction, but also ensures its movable position in the X and Y axes. Based on this, by setting an XY-axis adjustment module 300 connected to the lamp holder 400, fine-tuning of the lamp holder 400's position can be achieved, thereby moving the bulb along the X and Y axes. This allows for position calibration after bulb replacement, reducing measurement errors caused by bulb replacement.

[0058] Specifically, please refer to Figure 2 In this embodiment, a groove 410 is provided at the bottom of the lamp holder 400, and a conductive spring is provided in the groove 410. After the bulb's pins are inserted into the groove 410, they are fixedly connected to the conductive spring. By setting the groove 410 and the conductive spring at the bottom of the lamp holder 400 to form a physical hardware control, the replacement operation is greatly simplified, and the bulb can be replaced quickly.

[0059] Furthermore, for better bulb position calibration, please refer to [link / reference]. Figure 3 In this embodiment of the application, the T-shaped support 200 includes: a horizontal circular piece 210 and a vertical straight rod 220.

[0060] One end of the vertical rod 220 is vertically connected to the horizontal disc 210, and the other end of the vertical rod 220 passes through the first through hole 110 and is connected to the top of the lamp holder 400. The horizontal disc 210 covers the first through hole 110 and contacts the outer surface of the top of the housing 100.

[0061] The diameter of the first through hole 110 is larger than the diameter of the vertical rod 220 and smaller than the diameter of the horizontal disc 210.

[0062] Based on the above design, since the diameter of the horizontal disc 210 is larger than the diameter of the first through hole 110, and the diameter of the vertical rod 220 is smaller than the diameter of the first through hole 110, the lamp holder 400 can be suspended inside the housing 100 under the support of the horizontal disc 210 and the vertical rod 220, ensuring that the lamp holder 400 is fixed in the Z-axis direction and movable in the X-axis and Y-axis directions.

[0063] In one alternative implementation, please refer to Figure 3 and Figure 4 The XY axis adjustment module 300 includes: an adjustment rod 310, an X-axis adjustment component 320, and a Y-axis adjustment component 330.

[0064] Both the X-axis adjustment assembly 320 and the Y-axis adjustment assembly 330 are located outside the housing 100. One end of the adjustment rod 310 is connected to the side wall of the X-axis adjustment assembly 320, and the other end of the adjustment rod 310 passes through the second through hole 120 and is connected to the side wall of the lamp holder 400. The bottom of the X-axis adjustment assembly 320 is connected to the top of the Y-axis adjustment assembly 330. Furthermore, the bottom of the Y-axis adjustment assembly 330 can be mounted on the fixed base A so that the X-axis adjustment assembly 320 and the second through hole 120 are positioned in the Z-axis direction.

[0065] The X-axis adjustment assembly 320 is used to drive the adjustment rod 310 to move along the X-axis direction.

[0066] The Y-axis adjustment assembly 330 is used to drive the X-axis adjustment assembly 320 to move along the Y-axis direction, thereby driving the adjustment rod 310 to move along the Y-axis direction.

[0067] To better understand, the adjustment principles of the Y-axis adjustment component 330 and the X-axis adjustment component 320 will be explained below.

[0068] As an optional implementation, please refer to Figure 5 and Figure 6 The Y-axis adjustment assembly 330 includes: a first base 331, a first slider 332 and a first fixing rod 333 arranged parallel to the X-axis, a first slide rail 334, a second slide rail 335 and a first threaded rod 336 arranged parallel to the Y-axis.

[0069] The first fixing rod 333, the first slide rail 334, and the second slide rail 335 are all mounted on the first base 331.

[0070] The two ends of the first fixed rod 333 are perpendicularly connected to one end of the first slide rail 334 and the second slide rail 335, respectively. The first fixed rod 333 has a third through hole along the Y-axis, and the inner wall of the third through hole is provided with an internal thread that matches the first threaded rod 336. One end of the first threaded rod 336 passes through the third through hole and is perpendicularly connected to the side wall of the first slider 332.

[0071] The two ends of the first slider 332 are slidably connected to the first slide rail 334 and the second slide rail 335 respectively, and the top of the first slider 332 is fixedly connected to the bottom of the X-axis adjustment assembly 320.

[0072] Based on the above design, turning the first threaded rod 336 clockwise will cause the first slider 332 to move along the Y-axis on the first slide rail 334 and the second slide rail 335. Since the top of the first slider 332 is fixedly connected to the bottom of the X-axis adjustment assembly 320, the first slider 332 can drive the entire X-axis adjustment assembly 320 to move synchronously, thereby sequentially driving the adjustment rod 310, the lamp holder 400, and the bulb to move along the Y-axis.

[0073] As another alternative implementation, please refer to Figure 7 and Figure 8 The X-axis adjustment assembly 320 includes: a second base 321, a second slider 322 and a second fixed rod 323 arranged parallel to the Y-axis, a third slide rail 324, a fourth slide rail 325 and a second threaded rod 326 arranged parallel to the X-axis.

[0074] The second fixing rod 323, the third slide rail 324 and the fourth slide rail 325 are all mounted on the second base 321, and the bottom of the second base 321 is fixedly connected to the top of the first slider 332.

[0075] The two ends of the second fixed rod 323 are perpendicularly connected to one end of the third slide rail 324 and the fourth slide rail 325, respectively. The second fixed rod 323 has a fourth through hole along the X-axis, and the inner wall of the fourth through hole has an internal thread that matches the second threaded rod 326. One end of the second threaded rod 326 passes through the fourth through hole and is perpendicularly connected to the side wall of the second slider 322.

[0076] One end of the second slider 322 is slidably connected to the third slide rail 324, and the other end of the second slider 322 is fixedly connected to one end of the adjusting rod 310 and then slidably connected to the fourth slide rail 325.

[0077] Based on the above design, turning the second threaded rod 326 clockwise will cause the second slider 322 to move along the X-axis on the third slide rail 324 and the fourth slide rail 325. Furthermore, since one end of the adjusting rod 310 is fixedly connected to the second slider 322, the adjusting rod 310 can move synchronously with the second slider 322, thereby causing the lamp holder 400 to move along the X-axis.

[0078] Furthermore, please refer again. Figure 5 and Figure 8 In this embodiment, the XY axis adjustment module 300 further includes a connecting rod 340. One end of the connecting rod 340 is connected to the top of the first slider 332, and the other end of the connecting rod 340 is connected to the bottom of the second base 321.

[0079] The first slider 332 in the Y-axis adjustment assembly 330 is connected to the second base 321 in the X-axis adjustment assembly 320 via the connecting rod 340, so that the first slider 332 moves along the Y-axis direction, thereby driving the entire X-axis adjustment assembly 320 to move synchronously, thereby driving the adjustment rod 310 to move, and realizing the position adjustment of the lamp holder 400 in the Y-axis direction.

[0080] Based on the above design, by setting the lamp holder 400 and the bulb to a pluggable connection, quick bulb replacement is achieved, effectively avoiding drastic fluctuations in light intensity. The position of the lamp holder 400 is adjusted using the T-shaped support 200 and the XY-axis adjustment module 300 to eliminate bulb position errors, thereby greatly reducing measurement errors caused by bulb replacement.

[0081] Furthermore, during the replacement and adjustment of the bulb, the internal environment of the housing 100 is easily contaminated, causing particles to adhere to the surface of the bulb and other optical components, interfering with the light spot and thus leading to errors in the measurement results.

[0082] Therefore, to further reduce measurement errors caused by bulb replacement, please refer to [link / reference needed]. Figure 9 In this embodiment of the application, the measuring light box 10 also includes an exhaust fan 510 and a duct 520.

[0083] The exhaust fan 510 is connected to the pipe 520, and the exhaust fan 510 is embedded inside the housing 100, while the pipe 520 is located outside the housing 100.

[0084] The exhaust fan 510 is used to discharge particles inside the chamber 100 to the external environment through the pipe 520, thereby improving the cleanliness inside the chamber 100, reducing the impact of particles on the bulb, reducing the noise in the generated light, and improving the measurement accuracy of the measurement light box 10.

[0085] Optionally, please refer to Figure 10This application also provides a measurement system, which includes a bulb 20, a lens group, and a measurement light box 10 as described in any of the foregoing embodiments. The bulb 20 and the lens group are both located inside the box 100, and the bulb 20 is plugged into the bottom of the lamp holder 400.

[0086] Furthermore, the lens assembly includes a reflector 31 and multiple refractive lenses 32. The reflector 31 is disposed on the side of the bulb 20 away from the light outlet of the housing 100, and the multiple refractive lenses 32 are disposed on the side of the bulb 20 closer to the light outlet of the housing 100.

[0087] In summary, this application provides a measurement light box and system. The measurement light box includes: a housing, a T-shaped support, an XY-axis adjustment module, and a lamp holder. The lamp holder is located inside the housing, and its bottom is plugged into and connected to the light bulb. A first through-hole is provided on the top of the housing. The vertical portion of the T-shaped support passes through the first through-hole and connects to the top of the lamp holder. The horizontal portion of the T-shaped support covers the first through-hole and contacts the outer surface of the top of the housing. A second through-hole is provided on the side wall of the housing. One end of the XY-axis adjustment module passes through the second through-hole and connects to the side wall of the lamp holder. The other end of the XY-axis adjustment module is located outside the housing and is used to adjust the position of the lamp holder to move the light bulb.

[0088] By using a pluggable connection between the bulb and socket, rapid bulb replacement is possible within the confined space of the enclosure, avoiding drastic fluctuations in light intensity and reducing the difficulty and risk of error during replacement. A first through-hole at the top of the enclosure, connected to a T-shaped support, not only suspends the socket inside, ensuring its fixed position along the Z-axis, but also allows for movement along the X and Y axes. Furthermore, an XY-axis adjustment module connected to the socket enables fine-tuning of its position, moving the bulb along the X and Y axes for post-replacement calibration, thus reducing measurement errors caused by bulb replacement. Additionally, an exhaust fan and duct discharge particles from the enclosure to the external environment, improving internal cleanliness and further minimizing measurement errors due to bulb replacement.
