[0024] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] Please refer to Figures 1-3. This utility model provides a color matching light box for easy observation of metallic luster and texture, including a light source box 10, a lifting frame 20, and an observation box 30. The lifting frame 20 is installed on top of the observation box 30, and the light source box 10 is installed on top of the lifting frame 20. In use, the sample is placed inside the observation box 30. When the light source box 10 is working, it illuminates the sample inside the observation box 30, and the operator evaluates the color of the sample under different lighting conditions.

[0026] The heightening frame 20 has a rectangular frame structure that runs through both the top and bottom. The light source box 10 includes a light source box shell 11. The bottom of the light source box shell 11 is adapted to and fixedly connected to the top of the heightening frame 20. The top of the observation box 30 is adapted to and fixedly connected to the bottom of the heightening frame 20. Both of the above connections are sealed to prevent light leakage, which would affect color matching.

[0027] The observation box 30 has a hollow box structure with openings on the front and top. The front opening of the observation box 30 is used for taking out and putting in samples and for staff to observe and match colors. The top opening of the observation box 30 is used to allow light emitted from the light source box 10 to enter the observation box 30.

[0028] Referring to Figure 3, the light source box 10 also includes a reflector 12 and LED light panels 13. The reflector 12 is horizontally installed inside the housing 11 of the light source box. Multiple LED light panels 13 are mounted on the lower surface of the reflector 12 and are horizontally arranged. In this embodiment, the LED light panels 13 are arranged in two rows along the front-to-back direction, with three equally spaced LED light panels 13 in each row.

[0029] The reflector 12 is located above the LED light panel 13. It can reflect and refract the light inside the light source box housing 11, so that the light can be more evenly distributed into the observation box 30, thereby improving the utilization rate of the light source and helping to provide a stable, uniform and interference-free lighting environment.

[0030] A diffuser plate 21 is fixedly installed horizontally inside the heightening frame 20. The diffuser plate 21 is located below the light source box 10. It can diffuse the light emitted by the light source box 10, so that the light is evenly distributed in the observation box 30, avoiding local over-brightness or under-brightness, thereby improving the lighting effect.

[0031] Please refer to Figure 3. In this embodiment, the light source box 10 also includes a light source module 50. The light source module 50 is installed on the lower surface of the reflector 12. The light emitted by the light source module 50 can help the staff observe the texture of the metal surface gloss.

[0032] Specifically, referring to Figures 4-7, the light source module 50 includes a duct 51, an angle adjustment structure 52, a bracket 53, a lamp holder 54, and a light source 55. The duct 51 is fixedly connected to the reflector 12. The angle adjustment assembly 52 is installed inside the duct 51. The angle adjustment assembly 52 includes a fixed shaft 521 and a ball head 522 rotatably mounted on the lower end of the fixed shaft 521. The ball head 522 has a spherical structure. The bracket 53 is fixedly connected to the ball head 522. The lamp holder 54 is fixedly connected to the bracket 53. The light source 55 is installed inside the lamp holder 54. The light source 55 is an LED light source, which can provide light of different colors, allowing workers to observe the luster and texture color of the metal surface under different colors of light. Of course, in other embodiments not shown, the bracket 53 can be omitted. In this case, the lamp holder 54 is fixedly connected to the ball head 522, and the lamp holder 54 is rotatably mounted on the fixed shaft 521 of the angle adjustment structure 52 via the ball head 522.

[0033] Before use, by moving the bracket 53, the ball head 522 can rotate relative to the fixed axis 521, thereby enabling the angle adjustment function of the bracket 53, along with the lamp holder 54 and the lamp source 55. By adjusting the angle of the lamp source 55, the lamp source 54 can become a side light source. Side light sources can highlight the reflection and shadows on the metal surface, better showcasing the gloss and texture of the metal surface, thus enhancing the visual effect of the texture. In addition, changing the angle of the lamp source 55 can provide light at different angles, which is beneficial for workers to observe the gloss and texture structure of the metal surface under different angles of light.

[0034] In this embodiment, the air duct 51 is a square tube structure with both ends open. A vent (not shown) is provided on the reflector 12, and the vent is connected to the upper end of the air duct 51. During operation, the heat accumulated in the air duct 51 when the lamp source 55 is powered on can be dissipated through the vent, thus ensuring that the lamp source 55 maintains a normal operating temperature. Specifically, a cooling fan can be installed inside the air duct 51 near the vent to blow away the heat.

[0035] The ball head 522 has a spherical structure and a certain damping effect between the ball head 522 and the fixed shaft 521. On the one hand, it can improve the user's feel for rotating the bracket 53, and on the other hand, it can keep the rotating bracket 53 stably stopped at a specific position, effectively preventing the rotating bracket 53 from rotating easily.

[0036] In this embodiment, two limiting plates 531 are fixedly installed on the bracket 53. The two limiting plates 531 are located on opposite sides of the fixed shaft 521 and are in contact with the fixed shaft 521. The two limiting plates 531 are arranged parallel to each other. Thus, under the limiting action of the two limiting plates 531, the ball head 522 can only deflect along the limiting plane of the limiting plates 531, so that the ball head 522 can only rotate in one dimension, ensuring that the lamp source 55 itself will not rotate around the central axis of the fixed shaft 521, but only rotates in one direction.

[0037] In this embodiment, a heat dissipation component 541 is installed on the top of the lamp holder 54. The heat dissipation component 541 is used to conduct heat out of the lamp holder 54, thereby achieving heat dissipation. In a specific embodiment, the heat dissipation component 541 is a finned heat sink.

[0038] In this embodiment, a convex lens 56 is installed inside the lamp holder 54 below the lamp source 55 to focus the light, making the light emitted from the lamp source 55 more concentrated. Of course, in other embodiments, the convex lens 56 may be omitted.

[0039] In addition, an adapter plate 511 is fixedly installed inside the duct 51. The fixed shaft 521 is a cylindrical structure, and the upper end of the fixed shaft 521 is set as a flange structure. The flange structure is fixedly connected to the adapter plate 511. The flange structure and the adapter plate 511 can be fixed by fasteners such as bolts or screws.

[0040] In this embodiment, there are two light source modules 50 located on opposite sides of the diffuser plate 21. In other embodiments, there may be three light source modules 50, which is not limited here.

[0041] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
