[0047] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0048] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0049] Combine Figure 1-7 As shown, an embodiment of the present disclosure provides a color difference evaluation light source box, including a box body 10. The box body 10 includes a box body side wall 11 and a base 13. The box body side wall 11 and the base 13 are connected to enclose an internal space 14. The box body side wall 11 includes a telescopic section 12. The telescopic section 12 can be extended or contracted along the height direction of the box body 10 to adjust the height of the box body 10.

[0050] The height direction of the box 10 is as follows Figure 5 The telescopic section 12 can be moved along the direction of the arrow. Figure 5The box body 10 can be extended or contracted in the direction indicated by the arrow. The box side wall 11 includes a telescopic section 12, and the telescopic section 12 can be extended or contracted in the height direction, so that the height of the box body 10 can be adjusted. The box side wall 11 can be an entire telescopic section 12, or a portion of the box side wall 11 can be a telescopic section 12. When the box side wall 11 is an entire telescopic section 12, the box side wall 11 can be extended or contracted in the height direction of the box body 10 as a whole, which can increase the adjustment range of the height of the box body 10. When the telescopic section 12 is in the contracted state, the structure of the box body 10 can be more compact. When only a portion of the box side wall 11 is a telescopic section 12, part of the box side wall 11 is a fixed height, and part of the box side wall 11 is a telescopic section 12, thereby improving the efficiency of space utilization.

[0051] like Figure 1 As shown in , the telescopic section is in the extended state. Figure 2 As shown, the telescopic section is in a compressed state.

[0052] When the color difference evaluation light source box is idle, the telescopic section 12 of the box body 10 can be compressed to significantly reduce the volume of the box body 10. This makes it easier to carry the color difference evaluation light source box to the factory, and can achieve consistency between the color difference evaluation light source 60 tools at the development end and the factory end. The small, portable color difference evaluation light source box provided by the disclosed embodiment can achieve portability, lightweighting, and standardization of the color difference evaluation light source 60 tools used for the color conversion of industrial products, avoiding or reducing color difference evaluation errors and inefficient conversion caused by inconsistent factory light sources 60.

[0053] The color difference evaluation light source box provided by the embodiment of the present disclosure is used. By providing a telescopic section 12 on the side wall 11 of the box, the box 10 can be extended or contracted in the height direction, thereby adjusting the height of the box 10. When the telescopic section 12 is in the contracted state, the overall structure of the box 10 is more compact, which can reduce the volume of the box 10, thereby improving the portability of the color difference evaluation light source box. The color difference evaluation light source box with the telescopic section 12 in the contracted state is also convenient for transportation and storage. At the same time, the expansion and contraction of the telescopic section 12 can also provide a flexible internal space 14, so that the internal space can adapt to samples of different sizes, thereby improving the utilization rate of the internal space 14.

[0054] Optionally, the telescopic section 12 has a certain rigidity.

[0055] The telescopic section 12 has a certain rigidity that can improve the structural stability of the box body 10. When the telescopic section 12 is in the extended state, the telescopic section 12 can maintain its shape and size to avoid deformation or collapse.

[0056] Optionally, combined Figure 1As shown, the telescopic section 12 includes a folding ring 121, and the folding ring 121 includes a first folding edge 122 and a second folding edge 123. The first folding edge 122 and the second folding edge 123 are connected to form a first folding line 124 protruding outward; when there are multiple folding rings 121, the multiple folding rings 121 are connected in sequence along the height direction of the box body 10, and a second folding line 125 concave inward is formed between adjacent folding rings 121, so that the telescopic section 12 forms a corrugated structure.

[0057] The telescopic section 12 is extended or contracted via a folding ring 121. The folding ring 121 includes a first folding edge 122 and a second folding edge 123, which connect to form a first, outwardly protruding fold 124. When the folding ring 121 is compressed, the first and second folding edges 122, 123 are compressed to form the outwardly protruding first fold 124. When the folding ring 121 is extended, the first and second folding edges 122, 123 are stretched to extend along the height of the box body 10. The first fold 124, the first and second folding edges 122, 123 can be coplanar, allowing the box sidewall 11 to straighten, forming a straight cylindrical interior space 14.

[0058] The telescopic section 12 utilizes a corrugated structure formed by sequentially connecting multiple folding rings 121, giving the enclosure 10 a stretchable, accordion-like structure. This provides excellent elasticity for the telescopic section 12 and increases the strength and durability of the enclosure sidewalls 11. The design of the first and second folding lines 124, 125 ensures a smooth transition when the telescopic section 12 is extended and compactly stows when retracted, making it easier to adjust the height of the enclosure 10.

[0059] Optionally, combined Figure 1 、 Figure 3-4 and Figure 7 As shown, the box body 10 is provided with an opening 15 opposite to the base 13, and the color difference evaluation light source box also includes a top cover 20, which is provided on the opening 15, and the top cover 20 is provided with a connecting portion 21, and the side wall 11 of the box body is provided with a connecting mating portion 111, and the connecting portion 21 cooperates with the connecting mating portion 111 to make the top cover 20 and the box body 10 detachably connected.

[0060] By installing a top cover 20 over the opening 15 of the housing 10, the color difference evaluation light box is sealed in its operating mode. This sealed design effectively blocks interference from external light, such as ambient color and the observer's clothing color, ensuring stable and uniform lighting conditions within the light box, thereby improving color difference evaluation results.

[0061] The direction of disassembly of the top cover is as follows: Figure 3 As shown by the arrow in the middle, the installation direction of the top cover is as follows Figure 7 Indicated by the direction of the arrow. The detachable connection between the top cover 20 and the box body 10 allows the light source box to be opened quickly, which is convenient for placing and removing samples. At the same time, this also makes it convenient to install the top cover 20 after the box body 10 has completed the telescopic adjustment of the height, which can improve the flexibility of the light source box. When the light source box is in use, the height of the box body 10 can be adjusted to accommodate the sample, and then the top cover 20 can be installed. This makes it convenient to adjust the correct position and posture of the sample inside the light source box, so as to make an accurate evaluation. After the light source box is used, the top cover 20 can be removed first, and the top cover 20 can be installed after the side walls 11 of the box body are compressed. This can provide more operating space for the compression of the side walls 11 of the box body, making it easier to compress the side walls 11 of the box body. Removing the top cover 20 before compressing the side walls 11 of the box body can also avoid unnecessary damage to the top cover 20 or the box body 10 during the compression process.

[0062] Optionally, one of the connecting portion 21 and the connecting fitting portion 111 is an internal thread, and the other is an external thread, and the internal thread and the external thread are detachably matched.

[0063] The matching mode of the internal thread and the external thread makes the connection or disassembly of the top cover 20 and the box body 10 more convenient. The connecting portion 21 may be an internal thread, the connecting fitting portion 111 may be an external thread, the top cover 20 may be provided with an internal thread, the box body side wall 11 may be provided with an external thread, and the internal thread and the external thread may match to achieve a detachable connection between the top cover 20 and the box body side wall 11. The connecting portion 21 may also be an external thread, the connecting fitting portion 111 may be an internal thread, the top cover 20 may be provided with an external thread, the box body side wall 11 may be provided with an internal thread, and the internal thread and the external thread may match to achieve a detachable connection between the top cover 20 and the box body side wall 11. In the case where the telescopic section 12 is provided at the top of the box body side wall 11 or the box body side wall 11 is entirely composed of the telescopic section 12, the internal thread may be provided at the top of the telescopic section 12, and the external thread may be provided below the top cover 20.

[0064] Optionally, combined Figure 1-3 and Figure 5-7 As shown, the color difference evaluation light source box also includes an observation channel 50 and a light source 60. The observation channel 50 is arranged through the top cover 20; the light source 60 is arranged on the side of the top cover 20 facing the internal space 14, and the light source 60 is distributed along the circumference of the observation channel 50.

[0065] An observation hole 50 is provided through the top cover 20, through which the sample placed in the interior space 14 can be observed. A light source 60 is provided on the side of the top cover 20 facing the interior space 14 and is distributed circumferentially around the observation hole 50. This allows the light sources 60 to be evenly distributed around the sample, providing stable lighting conditions, facilitating accurate color difference assessment, and reducing assessment errors caused by uneven light sources 60.

[0066] Optionally, the light source 60 is a D65 standard light source lamp.

[0067] The D65 standard light source is an internationally accepted standard artificial daylight. Using D65 standard light source lamps can provide uniform, stable, and natural light-like lighting conditions, which is conducive to accurate color difference evaluation.

[0068] Optionally, combined Figure 1-3 and Figure 5-7 As shown, the color difference evaluation light source box further includes a light shielding cover 70 , which is disposed on the observation channel 50 .

[0069] The light shielding cover 70 is provided on the observation channel 50 to prevent dust and other impurities from entering the internal space 14 of the box 10 through the observation channel 50 when the product is not in use, thereby affecting the product life and color difference judgment.

[0070] Optionally, combined Figure 1-3 and Figure 5-7 As shown, the color difference evaluation light source box also includes a power supply 23 and a switch button 24. The power supply 23 is arranged between the top cover 20 and the light source 60, and the switch button 24 is arranged on the outside of the top cover 20. The power supply 23 is electrically connected to the light source 60 and the switch button 24 to control the switch of the light source 60.

[0071] A switch button 24 is located on the outside of the top cover 20, allowing the user to quickly turn the light source 60 on or off. Integrating the power supply 23, switch button 24, and light source 60 on the top cover 20 simplifies wiring. Pressing the switch button 24 switches the power supply 23 on and off, thereby turning the light source 60 on or off. The power supply 23 can be a battery.

[0072] Optionally, combined Figure 1 、 Figure 3 and Figure 7 As shown, the color difference evaluation light source box also includes a storage portion 30, which is arranged on the side of the base 13 facing the internal space 14; wherein, the storage portion 30 is provided with a groove 31, the size of the groove 31 is adapted to the plane size of the sample 90, and is used to place the sample 90 horizontally.

[0073] The base 13 is provided with a storage portion 30 on the side facing the interior space 14 for placing the sample 90 to be observed, so that the sample 90 can be accurately positioned at a specific location within the box 10. This can improve the consistency of the position of the sample 90 during each observation, thereby improving the uniformity of the observation conditions and the comparability of the evaluation results.

[0074] A recess 31 is provided in the storage portion 30 for horizontally placing the sample 90, providing a horizontal viewing angle for the sample 90. The dimensions of the recess 31 are compatible with the planar dimensions of the sample 90. This improves the stability of the sample 90 when placed horizontally in the recess 31, reducing potential movement or tilting during the evaluation process, thereby enhancing the accuracy of color difference evaluation. The dimensions of the recess 31 are compatible with the planar dimensions of the sample 90, allowing the recess 31 to accommodate samples 90 with planar dimensions equal to or smaller than the recess 31. Multiple samples 90 can be placed simultaneously in the recess 31 for simultaneous color comparison.

[0075] Optionally, combined Figure 1 、 Figure 3 and Figure 7 As shown, the color difference evaluation light source box also includes a storage portion 30, which is arranged on the side of the base 13 facing the internal space 14; wherein, the storage portion 30 is provided with a card slot 32, the size of the card slot 32 is adapted to the thickness of the sample 90, and is used to vertically place the sample 90.

[0076] A slot 32 is provided in the storage portion 30 for vertically placing the sample 90, providing a vertical observation angle for the sample 90. The size of the slot 32 is compatible with the thickness of the sample 90. When the sample 90 is placed vertically in the slot 32, the stability of the sample 90 is improved, reducing the possibility of movement or tilting during the evaluation process, thereby improving the accuracy of the color difference evaluation.

[0077] There can be multiple slots 32, with the multiple slots 32 extending along the length of the storage portion 30 and spaced apart along the width of the storage portion 30. Alternatively, the multiple slots 32 can extend along the width of the storage portion 30 and spaced apart along the length of the storage portion 30. This allows multiple samples 90 to be placed in the multiple slots 32 simultaneously for simultaneous color comparison.

[0078] This application uses the example of a storage portion 30 having both a groove 31 and a slot 32. When performing color difference evaluation, samples 90 can be placed horizontally on the groove 31 of the storage portion 30, or vertically inserted into the slot 32 of the storage portion 30 according to actual needs.

[0079] Exemplarily, the storage portion 30 is a slot 32 plate extending horizontally. A groove 31 is provided on the upper surface of the slot 32 plate for horizontally placing the sample 90. Multiple slots 32 are provided on the bottom wall of the groove 31, spaced apart along the length or width of the groove 31 for vertically placing the sample 90. By providing both the slots 32 and the groove 31 on the storage portion 30, the storage portion 30 can accommodate different placement angles for the sample 90, thereby improving the versatility and applicability of the light source box. By providing multiple slots 32 on the bottom wall of the groove 31 and integrating the groove 31 and the slots 32 together, more placement locations for the sample 90 can be provided within a limited space, thereby improving the space utilization of the storage portion 30.

[0080] Optionally, combined Figure 1 、 Figure 2 and Figure 5 As shown, the storage portion 30 and the observation channel are arranged opposite to each other along the height direction of the box body 10.

[0081] The observation channel is positioned opposite the storage portion 30, allowing the user to directly observe the sample 90 in the storage portion 30 through the observation channel. The light source 60 is distributed circumferentially along the observation channel 50, providing uniform illumination around the sample 90. This reduces brightness variations on the sample surface, avoids shadows or highlights, and thus improves the accuracy of color assessment.

[0082] Optionally, combined Figure 1-3 and Figure 5-7 As shown, the color difference evaluation light source box further includes a first storage portion 33 , which is disposed between the storage portion 30 and the base 13 for storing accessories.

[0083] The first storage section 33 is used to store color samples and other easily lost small accessories. Located between the storage section 30 and the base 13, the first storage section 33 facilitates quick access to accessories during color difference evaluation, improving work efficiency. Furthermore, the first storage section 33, located between the storage section 30 and the base 13, fully utilizes the vertical space within the case 10, allowing accessories to be stored without occupying additional space, thereby improving the efficiency of the internal space 14 of the case 10.

[0084] Optionally, the first receiving portion 33 includes a box body having an internal cavity.

[0085] The inner cavity of the box structure can accommodate accessories, and at the same time, the box structure can also play a supporting role for the object placement portion 30. It is understood that the first storage portion 33 can also be a storage structure such as a concave groove.

[0086] Optionally, combined Figure 2 and Figure 3As shown, the color difference evaluation light source box also includes a protective portion 40, which is arranged on two opposite sides of the storage portion 30, and the height of the protective portion 40 is higher than the height of the storage portion 30; wherein, the top cover 20 is provided with an abutment portion 22 corresponding to the protective portion 40, and when the telescopic section 12 is in a retracted state, the protective portion 40 can abut against the abutment portion 22 to form a protective space 42 between the protective portion 40 and the abutment portion 22.

[0087] The height of the protective portion 40 is higher than the storage portion 30. The protective portion 40 abuts against the abutting portion 22 of the top cover 20 to form a protective space 42, which can effectively prevent collisions between components such as the light source 60 provided on the top cover 20 and components such as the storage portion 30 provided on the base 13. The protective portion 40 is provided on opposite sides of the storage portion 30, and can form support for the top cover 20 on both sides of the storage portion 30, providing uniform support force for the top cover 20, thereby improving the protective effect.

This ensures that the telescopic section 12 maintains excellent performance during frequent expansion and contraction. Furthermore, TPU possesses high rigidity, maintaining the stability and uprightness of the box sidewall 11 when the telescopic section 12 is in the extended state.

[0096] Optionally, the top cover 20 is made of acrylonitrile-butadiene-styrene copolymer material.

[0097] Acrylonitrile butadiene styrene (ABS) is a thermoplastic material with good dimensional stability and is not easily deformed by temperature changes, which can improve the sealing and durability of the top cover 20. ABS plastic also has excellent impact resistance, which can improve the stability of the top cover 20.

[0098] Optionally, the protective portion 40 is made of thermoplastic polyurethane elastomer material.

[0099] Thermoplastic polyurethane (TPU) has excellent elasticity, allowing the guard 40 to quickly return to its original shape when subjected to external forces, maintaining the structural stability and reliability of the guard 40. TPU also has high strength and toughness, capable of withstanding significant impact forces, enhancing the impact resistance and shock absorption performance of the guard 40. This prevents damage to components located on the top cover 20 and components located on the base 13 from colliding, while also reducing impact and vibration between the top cover 20 and the base 13.

[0100] Optionally, the RGB values ​​of the colors of the inner surface of the box side wall 11 , the inner surface of the top cover 20 , and the inner surface of the base 13 are (212, 215, 221).

[0101] The RGB values ​​for the inner surfaces of the sidewalls 11, the top cover 20, and the base 13 are all set to (212, 215, 221). This uniformly sets the inner surface of the box 10 to a neutral, light gray. This reduces the impact of color reflection on the evaluation results, thereby improving the accuracy of the evaluation. The inner surface of the inner wall of the box 10, including the inner surface of the telescopic section 12, also has RGB values ​​of (212, 215, 221).

[0102] Optionally, combined Figure 1-7 As shown, the color difference evaluation light source box also includes an inflation valve 80 , which is provided on the side wall 11 or the base 13 of the box body. The inflation valve 80 is connected to the internal space 14 and is used to supply air to the internal space 14 .

[0103] The direction in which the air pump delivers air to the interior space is as follows Figure 6 As shown in the direction of the arrow, the air flows along Figure 6 The air valve 80 moves in the direction of the middle arrow to fill the internal space. A first through hole can be provided on the side wall 11 of the box body, and the inflation valve 80 is connected to the internal space 14 through the first through hole, so as to supply air to the internal space 14. A second through hole can also be provided on the top of the base 13, and the inflation valve 80 is connected to the internal space 14 through the second through hole, so as to supply air to the internal space 14. Air can be supplied to the internal space 14 of the box body 10 through the inflation valve 80, which can increase the pressure of the internal space 14, improve the stability of the telescopic section 12 in the stretched state, and effectively maintain the shape of the box body 10. The air pressure of the internal space 14 can also be adjusted through the inflation valve 80 to simulate different environmental conditions to meet specific color difference evaluation requirements. The inflation valve 80 can be an electric inflation valve 80, which can improve the convenience of use. The inflation valve 80 can also be equipped with a pressure gauge to display the air pressure, so that the air pressure of the internal space 14 can be accurately controlled as needed.

[0104] Optionally, the base 13 is provided with a second receiving portion for receiving a power cord.

[0105] The base 13 plays an integral supporting role. A second storage portion is provided on the base 13, which is specifically used to store the power cord, so that the power cord can be stored in an orderly manner, avoiding the power cord being scattered inside or outside the box body 10, and improving neatness and aesthetics.
