Description

Technical Field

[0001] This utility model relates to the field of light box technology, and in particular, to a test light box that is easy to adjust the illumination angle. Background Technology

[0002] An experimental lightbox is an instrument used for experimental lighting. It features high brightness, high uniformity, and adjustable color temperature to provide a stable and uniform lighting environment for observing and photographing experimental objects. Existing experimental lightboxes typically have fixed lighting systems or only simple moving functions. In some applications, it's necessary to ensure that the light consistently illuminates the center of the lightbox's bottom. Adjusting the lighting angle often requires operating both the moving and lighting mechanisms separately, a cumbersome process that makes it difficult to guarantee that the light consistently illuminates the center of the lightbox's bottom before and after adjustment. Offsets in the lighting center can affect the consistency of multiple experiments, leading to inaccurate results.

[0003] Therefore, it is necessary for the inventors to improve the existing angle adjustment mechanism of the light box to overcome the above-mentioned defects. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to overcome the above-mentioned defects in the prior art, an experimental light box that is easy to adjust the illumination angle is provided.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an experimental light box that is easy to adjust the illumination angle, including a light box body, a slide base slidably installed on the top of the light box body, an illumination component installed on the slide base, an arc-shaped groove opened on the slide base, the center of the arc-shaped groove being located at the bottom center of the light box body, the illumination component being slidably connected to the slide base along the curvature direction of the arc-shaped groove, and the illumination center optical axis of the illumination component being arranged radially along the arc-shaped groove.

[0006] Furthermore, the lighting component includes a square bucket, and the arc-shaped groove has two concentrically arranged slots. Two locking members are installed on the square bucket, and the two locking members respectively pass through the two arc-shaped grooves and can slide along the corresponding arc-shaped grooves.

[0007] Furthermore, the locking element is a cylindrical structure, the outer diameter of the locking element is consistent with the width of the arc-shaped groove, and the outer wall of the locking element is in contact with the groove wall of the arc-shaped groove.

[0008] Furthermore, the locking element is a bolt, the tail of which passes through an arc-shaped groove and is threaded into the square bucket.

[0009] Furthermore, positioning grooves are arranged at equal intervals along the bending direction of the arc-shaped groove on the groove wall, and the positioning grooves are formed by the inward indentation of the groove wall of the arc-shaped groove.

[0010] Furthermore, the slide block is marked with graduations corresponding to the positioning groove.

[0011] Furthermore, the slide has an arched structure, and two arc-shaped grooves are provided on each of the opposite sides of the slide. The two sides of the square bucket are slidably connected to the arc-shaped grooves on both sides of the slide.

[0012] Furthermore, a support frame is formed on the top of the light box body, and a sliding groove is provided on the support frame. A slider is installed on the top of the slide block, and the slider is slidably connected to the sliding groove.

[0013] Furthermore, a protective shell is fixedly installed on the top of the light box body. The protective shell is sleeved on the outside of the support frame. The bottom of the protective shell has an opening through which the lower end of the lighting component passes. A top cover is detachably installed on the upper end of the protective shell.

[0014] The beneficial effects of this invention are as follows: The experimental lightbox of this invention, which facilitates the adjustment of the illumination angle, ensures that the illumination center of the illumination component remains locked at the center of the bottom of the lightbox body when the illumination component slides relative to the slide block. This allows for observation of the object and eliminates the phenomenon of illumination center offset that occurs during the movement and angle adjustment of traditional lightboxes, ensuring consistency across multiple experiments and guaranteeing the accuracy of experimental results. Furthermore, users can adjust the illumination angle by simply sliding the illumination component to align the light axis of the illumination center with the center of the bottom of the lightbox body, making operation convenient and greatly improving adjustment efficiency.

[0020] 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.

[0021] Please see Figures 1-3 This utility model provides an experimental light box with an adjustable illumination angle, including a light box body 10. A slide base 20 is slidably mounted on the top of the light box body 10. An illumination component 30 is mounted on the slide base 20. An arc-shaped groove 21 is formed on the slide base 20. The center of the arc-shaped groove 21 is located at the bottom center of the light box body 10. The illumination component 20 is slidably connected to the slide base 20 along the curvature direction of the arc-shaped groove 21. The illumination center optical axis of the illumination component 30 is arranged radially along the arc-shaped groove 21.

[0022] This invention provides an experimental lightbox with easily adjustable illumination angles. The position of the illumination component 30 can be adjusted by sliding it along the arc-shaped groove 21. Since the center of the arc-shaped groove 21 is located at the bottom center of the lightbox body 10, and the illumination center optical axis of the illumination component 30 is radially arranged along the arc-shaped groove 21, the illumination center of the illumination component 30 is always locked at the bottom center of the lightbox body 10 when sliding relative to the slide block 20. This eliminates the phenomenon of illumination center offset during movement and angle adjustment in traditional lightboxes, ensuring consistency across multiple experiments and guaranteeing the accuracy of experimental results. Furthermore, users can adjust the illumination angle while aligning the illumination center optical axis with the bottom center of the lightbox body 10 simply by sliding the illumination component 30, making operation convenient and greatly improving adjustment efficiency. Additionally, horizontally moving the slide block 20 relative to the lightbox body 10 allows for the adjustment of any non-central lateral position of the illumination component 30 under vertical illumination, meeting experimental needs. In other words, when the horizontally moving slide 20 prevents the light box body 10 from passing through the bottom center, the light assembly 30 does not adjust its angle. At this time, the light assembly 30's central optical axis only illuminates vertically downwards.

[0023] In a preferred embodiment, the lighting assembly 30 includes a square hopper 31 and two concentric arc-shaped grooves 21. Two locking members 32 are mounted on the square hopper 31, each penetrating one of the two arc-shaped grooves 21 and capable of sliding along the corresponding arc-shaped groove. In this embodiment, the locking member 32 is a cylindrical structure, with its outer diameter matching the width of the arc-shaped groove 21, ensuring that the outer wall of the locking member 32 fits against the wall of the arc-shaped groove 21. Thus, during the sliding motion of the lighting assembly 30 relative to the slide block 20, the two locking members 32 can slide stably along the arc-shaped groove 21, ensuring that the line connecting the two locking members 32 is always radially aligned with the arc-shaped groove 21. This, in turn, ensures that the central optical axis of the lighting assembly 30 is always radially aligned with the arc-shaped groove 21, guaranteeing that the central optical axis of the lighting assembly 30 passes through the bottom center of the light box body 10.

[0024] In this embodiment, the locking element 32 is a bolt. The tail of the bolt passes through the arc-shaped groove 21 and is threadedly connected to the square bucket 31. Tightening the bolt allows the head of the bolt to press against the side wall of the slide block 20, thereby locking the square bucket 31 onto the slide block 20. When it is necessary to adjust the lighting component 30, simply loosen the bolt, adjust it to the desired position, and then tighten the bolt again. The operation is simple and convenient. Of course, in other embodiments not shown, the threaded hole on the square bucket 31 can also be designed as a light hole. In this case, the user can pass the tail of the extended bolt through the arc-shaped groove 21 and the light hole in sequence, install a nut on the tail of the extended bolt, and tighten the nut to lock the square bucket 31 onto the slide block 20.

[0025] In practice, there is a certain mutual squeezing force between the outer surface of the locking component 32 and the groove wall of the positioning groove 22. When adjusting the lighting component 30, the user needs to overcome a certain frictional resistance to move the lighting component 30 relative to the slide 20. On the one hand, this avoids the lighting component 30 from being too smooth to make it difficult for the user to make precise adjustments, and on the other hand, it improves the user's operating feel.

[0026] In a preferred embodiment, positioning grooves 22 are arranged at equal intervals along the curvature direction of the arc-shaped groove 21 on the groove wall. The positioning grooves 22 are formed by the inward indentation of the groove wall of the arc-shaped groove 21. By providing positioning grooves 22, when the locking member 32 slides along the arc-shaped groove 21 to align with any positioning groove 22, the locking member 32 will engage in the positioning groove 22. Therefore, when the locking member 32 moves from one positioning groove 22 to the next adjacent positioning groove 22, the user will know that the lighting component 30 has deflected at a certain specific angle, making it easier for the user to adjust efficiently.

[0027] Furthermore, the slide 20 is marked with graduations 23 corresponding to the positioning groove 22 to facilitate user adjustment. In this embodiment, the graduation accuracy is 1°, that is, the angular deviation between any two adjacent positioning grooves 22 is 1°. In addition, the deflection angle of the arc groove 21 is limited to ±10°, that is, the center of the arc groove 21 is zero, and the maximum deflection angle to the left or right is 10°.

[0028] The lighting assembly 30 also includes a light source 34, which is fixedly mounted on the square container 31. The light source 34 includes a light box, LED beads disposed inside the light box, and a diffuser plate installed at the bottom of the light box. When the light source 34 is powered on, the light generated passes downward through the diffuser plate and illuminates the center of the bottom of the light box body 10. The light source 34 can adopt a light source structure in the prior art, which will not be described in detail here.

[0029] In this embodiment, the slide 20 is generally arched, and two arc-shaped grooves 21 are provided on both sides of the slide 20. Correspondingly, the two sides of the square bucket 31 are slidably connected to the arc-shaped grooves 21 on both sides of the slide 21, so that the lighting component 30 can be stably installed on the slide 20.

[0030] A support frame 11 is formed on the top of the lightbox body 10. The support frame 11 has a door-shaped structure and a sliding groove 111 is provided on the support frame 11. A slider 24 is installed on the top of the slide block 20, and the slider 24 is slidably connected to the sliding groove 111. In use, the user slides the slide block 20 horizontally, and the slider 24 slides along the sliding groove 111, so that the slide block 20 can be stably suspended on the support frame 11. In a specific implementation, the slider 24 can be set as an inverted U-shaped structure to prevent the slider 24 from separating from the sliding groove 111.

[0031] Furthermore, a protective housing 12 is fixedly installed on the top of the light box body 10. The protective housing 12 is fitted over the support frame 11. The bottom of the protective housing 12 has an opening through which the lower end of the lighting component 30 passes. A top cover 13 is detachably installed on the upper end of the protective housing 12. After the user removes the top cover 13, the angle of the lighting component 30 can be adjusted.

[0032] 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.
