The height of the upper end of the light shielding part 210 can be adjusted by sliding the first connection pipe 230 up and down, and the structure of the darkroom module 200 can be simplified. Of course, in other embodiments, the vertical pipes 220 can be extended and contracted up and down, the first connection pipe 230 is disposed between two corresponding adjacent vertical pipes 220, and the height of the light shielding portion 230 can be adjusted by extending and contracting the vertical pipes 220 up and down.

Regarding the number of the first connecting pipes 230 and the risers 220, the embodiment of the present invention is not particularly limited as long as the shadowless lamp 30 can be effectively wrapped and the optical test can be effectively performed on the shadowless lamp 30. As an example, as shown in fig. 2, the number of the risers 220 and the first connecting pipes 230 is 4, 4 risers 220 are surrounded to form a structure with a rectangular cross section, and one first connecting pipe 230 is arranged between two adjacent risers 220. Note that the upper end of the light shielding portion 210 is suspended from each of the first connection pipes 230.

Regarding the manner in which the first connection pipe 230 is locked on the riser 220, as an example, see fig. 2, the first connection pipe 230 is locked on the first connection pipe 230 by an angle joint 260. In order to match the lifting of the mounting part 110 of the hanger module 100, the riser pipe 220 can move up and down, after the height of the adapter base is moved to the proper position, the first connection pipe 230 is connected with the riser pipe 220 through the fixing screw and the angle connector 260, the height of the first connection pipe 230 is locked, and the shadowless lamp 30 is wrapped inside the darkroom module 200 by the shading part 210.

The first light-shielding member 211 and the second light-shielding member 212 made of flexible materials can tightly wrap the shadowless lamp 30 in the darkroom modules 200 with different shapes, so that the accuracy of optical testing on the shadowless lamp 30 is improved. It is understood that a portion of the first and second light-shielding

members

211 and 212 are respectively disposed on the top of the darkroom module 200 to shield the top of the darkroom module 200; the remaining first and second light-shielding

members

211 and 212 are respectively disposed at the sides of the darkroom module 200 to shield the sides of the darkroom module 200. Of course, in other embodiments, the light shielding portion 210 may also include three light shielding members, one of which is used for shielding the top of the darkroom module 200, and the other two of which are used for shielding the sides of the cued module 200 and have a gap therebetween for forming the opening 210 a.

The first light shielding member 211 and the second light shielding member 212 may be suspended on the first connecting pipe 230 by using hooks, velcro tapes, etc.

Alternatively, the lengths of the first and second light-shielding

members

211 and 212 are greater than or equal to the maximum height that the first connection pipe 230 can rise. Therefore, the first shading part 211 and the second shading part 212 can be directly dragged on the ground, and the shading of light rays is enhanced.

Optionally, a zipper, a magic tape or a strap for closing the extension opening of the shadow light boom is disposed between the first shade 211 and the second shade 212. After the shadowless lamp 30 is inserted into the darkroom module 200 by the shadowless lamp suspension arm 20, the gap between the first light-shielding member 211 and the second light-shielding member 212, i.e. the opening 210a, is eliminated by using a zipper, a velcro tape or a strap, thereby improving the light-shielding effect of the first light-shielding member 211 and the second light-shielding member 212. It is understood that when the zipper is employed, a smaller gap between the first light blocking member 211 and the second light blocking member 212 is required; when the hook and loop fastener or the strap is used, it is necessary to have an overlapping portion between the first and second light-shielding

members

211 and 212. No matter the zipper or the magic tape or the bandage is adopted, in order to ensure the shading effect, the zipper, the magic tape and the bandage can be made of black materials.
