[0027] There are two high-pressure spherical xenon lamps 10 , which can perform simulated solar detection operations on the photovoltaic components 7 of the group to be detected.

[0028] Among them, the transmission assembly 4 includes a first gear 41 fixedly connected to the outside of the transmission threaded rod 3, the top of the mounting frame 2 is rotatably connected to the transmission rod 42, the outside of the transmission rod 42 is fixedly connected to the second gear 43, and the outside of the first gear 41 and the outside of the second gear 43 are both transmission-connected to the rack 44.

[0029] The second gear 43 can be rotated by rotating the transmission rod 42, thereby driving the first gear 41 to rotate, and further driving the threaded rod 3 to rotate.

[0030] Among them, the top of the mounting frame 2 is fixedly connected to a protective shell, the top of the transmission threaded rod 3 is rotatably connected to the inner side of the protective shell, the first gear 41 and the second gear 43 are both located on the inner side of the protective shell, and the top of the transmission rod 42 is fixedly connected to a rotating handle.
