[0034] The light conversion film testing tooling provided by this application is applicable to the testing method as shown in the content disclosed in the document of CN220625707U, and the basic principle is as follows: The light source emits light, the light is incident on the light conversion film, and the incident light that has been converted is further filtered through the filter. The un-converted part of the incident light is excluded from the filtered outgoing light, so the outgoing light is the converted outgoing light. Another light is directly incident on the tooling without the light conversion film and the filter installed. The light conversion rate can be calculated based on the outgoing light of the two beams of light.

[0035] Embodiment 1

[0036] This embodiment provides a light conversion film testing tooling, including a base structure 1, a filter carrier part 2 arranged on the base structure 1, and a light conversion film fixing part 3 detachably connected to the filter carrier part 2.

[0037] In this embodiment, the filter carrier 2 includes a base body 201, a bottom groove 202 provided on the base body 201 and adapted to the filter a, a placement groove 203 provided on the base body 201 and communicating with the bottom groove 202, and an embedded track 204 provided on the groove side walls of the placement groove 203 and the bottom groove 202 and adapted to the filter a. Among them, the base body 201 itself has a through hole for light to pass through unobstructed. The bottom groove 202 refers to a semi-circular groove, or a major arc bow groove, or a minor arc bow groove adapted to the shape of the filter a, and the bottom groove 202 is provided in the middle of the base body 101; the placement groove 203 refers to a vertical groove body with an open upper end and a size corresponding to the diameter of the bottom groove 202; the embedded track 204 is provided on the two inner groove walls of the placement groove 203 and the groove wall of the bottom groove 202, and all the embedded tracks communicate with each other, and the width is equivalent to the thickness of the filter a; such a setting is beneficial to the fixation of the filter a and avoids its sliding.

[0038] As a further preference of this embodiment, the filter carrier 2 further includes a hinge rod 205 provided on the base body 201 and rotatably connected to the base structure 1, and a fixing rod 206 provided at the end of the embedded track 204 away from the bottom groove 202 for fixing the filter a. More preferably, the fixing rod 206 includes a rod body 206a with one end rotatably installed on the embedded track 204 and the other end extending towards the middle of the placement groove 203, a torsion spring 206b provided at the hinge joint of the rod body 206a and the embedded track 204, and a cushion layer 206c provided at the end of the rod body 206a away from the embedded track 204 for contacting the filter a. Among them, the precondition for installing the fixing rod 206 is not to interfere with the placement path of the filter a, and when the rod body 206a is not subjected to external force and is only affected by the torsion spring 206b, it maintains a state parallel or tending to be parallel to the bottom groove 202; after the external force overcomes the acting force of the torsion spring 206b, the rod body 206a can be rotated close to the bottom surface of the embedded track 204, and the filter a can pass through the fixing rod 206 smoothly. When the filter a contacts the bottom groove 202, the external force is withdrawn, and the torsion spring 206b makes the rod body 206b return to its original state. At this time, the lower surface of the rod body 206b abuts against the upper end of the filter a, and together with the bottom groove 202, the filter a is further strengthened; the cushion layer 206c is preferably made of common materials such as rubber to reduce the wear of the rod body 206b on the filter. The specific structure and installation method of the torsion spring 206b are well known to those skilled in the art, so they will not be elaborated here.

[0039] In this embodiment, the base structure 1 includes a base 101, a light passing hole 102 provided on the base 101, a side slot 103 provided on the base 101, located in the middle of the light passing hole 102 and for installing the seat body 201, and a hinge slot 104 provided in the side slot 103 and for installing the hinge rod 205. Among them, the base 101 defines the front and back sides with two sides perpendicular to the incident light, then the left or right single side or both left and right slots of the side slot 103 are open, so that the seat body 201 can rotate at least 90 degrees with the hinge rod 205 as the rotation center. Further, the upper side of the side slot 103 can also be open to facilitate the rotation operation of the seat body 201.

[0040] In this embodiment, the base structure 1 further includes a first magnet 105 provided on the base 101 and located at the side end of the light passing hole 102; a second magnet 301 that attracts the first magnet 105 is provided on the light conversion film fixing part 3. It can be understood that the first magnet 105 can also be directly replaced with a magnetically adsorbable material (usually iron), and a single second magnet 301 can also make the light conversion film fixing part 3 as a whole adsorbed on the base 101.

[0041] The light conversion film test tooling provided in this embodiment, compared with the prior art, its advantages at least include: First, through the structural settings of the base structure and the filter carrying part, the replacement of the filter can be greatly facilitated, improving work efficiency; Second, through the detachable connection between the light conversion film fixing part and the base structure, the convenience of replacing the light conversion film is further improved. Third, since the light conversion film fixing part can be detached and the filter carrying part can rotate, when testing the blank control group, it can be directly measured by removing the above two, without using a spectrophotometer to split the light source into two beams, simplifying the experimental apparatus and reducing the occupied volume of the device.

[0042] Embodiment 2

[0043] In this embodiment, the structure of the light conversion film fixing part 3 is optimized on the basis of Embodiment 1, specifically as follows:

[0045] The advantage of such a setting is that the light conversion film can be fixed by the combined clamping of the connecting plate and the fixing plate, without the need for precise cutting of the light conversion film, which is convenient for fixing; and the connection between the connecting plate and the fixing plate is realized by magnetic adsorption, which is convenient for disassembly and further improves the convenience of replacing the light conversion film.

[0046] Embodiment 3

[0047] In this embodiment, on the basis of Embodiment 2, the structure of the light conversion film fixing part is strengthened, specifically as follows:

[0048] The light conversion film fixing part 3 further includes a positioning groove 307 provided on the surface of the fixing plate 304 close to the connecting plate 302 and on the periphery of the second through hole 305, and a positioning pin 308 snap-fitted on the positioning groove 307 for fixing the light conversion film b; the surface of the positioning pin 308 has the third magnet 306.

[0049] In this embodiment, the positioning groove 307 is a countersunk head groove, and a limiting protrusion 309 is provided on the side wall of the countersunk head groove close to the bottom surface of the groove.

[0050] As a further preference of this embodiment, the base structure 1 further includes a placement groove 110 provided on the sliding seat 105 and used for placing the positioning pin 308. The provision of the placement groove is beneficial to the storage of the positioning pin when it is idle and avoids loss.

[0051] The advantage of such a setting in this embodiment is that: on the basis of being easily detachable, the fixing effect on the light conversion film is further improved, ensuring that the light conversion film remains in a taut state, and thus ensuring the accuracy of the test.

[0052] Embodiment 4

Among them, the sliding groove 107 is a side opening parallel to the light incident direction. Such a setting can enable one or two or even more than two filter bearing parts to be fixed on the sliding seat at the same time, so that the light passing through a single light conversion film can be directly filtered by two or even more than two filters, and the final required experimental data can be obtained in one step, greatly reducing the time required for the experiment and improving the work efficiency.

[0055] As a further preference of this embodiment, two fourth magnets may also be provided on the adjacent sides of the two bases 101 for attracting each other to connect the two bases 101, so as to ensure the tightness of the connection between the two bases 101.

[0056] As a further preference of this embodiment, the matrix structure 1 further includes a support plate 111 provided on the sliding seat 105 and used for supporting the light conversion film fixing part 3.
