[0035] Please refer to Figure 2 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 8The replacement assembly 300 comprises a base 301 fixed on the mounting frame 100, a sliding hole 302 is formed in the middle of the base 301 and extends through both ends, the sliding hole 302 is a straight-through hole with equal diameter, a sliding column 303 is slidably connected inside the sliding hole 302, the sliding column 303 is a column structure, the sliding column 303 is vertically fixed at the center position of the LED module unit 200, the sliding column 303 can be bonded on the LED module unit 200 or soldered on the LED module unit 200, the specific condition is selected according to actual use, a guide head 304 is vertically fixed at the end of the sliding column 303 away from the LED module unit 200, the cross sections of the guide head 304 and the combination head 305 are circular shapes, and the cross section diameters of the guide head 304 and the combination head 305 are the same, the combination head 305 is slidably connected outside the middle of the sliding column 303, in actual use, the thickness of the combination head 305 is greater than that of the limiting guide block 308 and the sliding distance of the combination head 305 is less than the thickness value of the limiting guide block 308, and the side of the sliding column 303 close to the LED module unit 200 is fixed with a limiting ring 306 for limiting the position of the combination head 305, the limiting ring 306 limits the sliding distance of the combination head 305, the base 301 is fixed with a sliding sleeve 307 corresponding to the position of the adjusting assembly 400, the sliding sleeve 307 is welded on the base 301, the base 301 is slidably connected with a limiting guide block 308 between the guide head 304 and the combination head 305, the limiting guide block 308 is a wedge block, the wedge block is prior art and will not be described here, the limiting guide block 308 is fixed with a sliding rod 309 along the direction of the sliding sleeve 307, the sliding rod 309 is used for connecting the limiting guide block 308, the sliding rod 309 slides inside the sliding sleeve 307 and the base 301, the middle of the sliding sleeve 307 is fixed with a stop ring 3010 for limiting the position of the sliding rod 309, the stop ring 3010 is used to limit the position of the sliding rod 309, the outside of the sliding rod 309 is sleeved with a reset member 3011 between the stop ring 3010 and the limiting guide block 308, the reset member 3011 adopts a reset spring.

[0036] When installing, the sliding column 303 on the LED module unit 200 is inserted into the base 301, at this time, the sliding column 303 is inserted to drive the guide head 304 to extrude the limiting guide block 308, the limiting guide block 308 is extruded to drive the sliding rod 309 to move outward in the sliding sleeve 307, at the same time, the return member 3011 is stretched, the guide head 304 continues to extrude into the sliding hole 302, when the guide head 304 is on one side of the limiting guide block 308, the combination head 305 is limited by the limiting guide block 308 to slide to the direction of the limiting ring 306, when the guide head 304 is completely on one side, the combination head 305 is just slid to the position of the limiting ring 306, as a result, the guide head 304 and the combination head 305 are respectively on the two sides of the limiting guide block 308, the limiting guide block 308 is clamped between the guide head 304 and the combination head 305, at the same time, when the limiting guide block 308 is no longer extruded by the guide head 304, the return member 3011 restores the deformation, the guide head 304 is tightly clamped between the guide head 304 and the combination head 305 through the sliding rod 309, so as to complete the installation of the LED module unit 200; when disassembling, only need to press the LED module unit 200 inward, the LED module unit 200 will move the guide head 304 and the combination head 305 into the sliding hole 302 through the sliding column 303, because the combination head 305 is limited by the limiting ring 306, the combination head 305 will extrude the limiting guide block 308, so that the combination head 305 also moves to one side of the guide head 304, when no longer pressing, the return member 3011 restores the deformation to drive the limiting guide block 308 to move to the direction of the combination head 305, at the same time, the adjusting assembly 400 is also compressed when pressing, when no longer pressing, the adjusting assembly 400 also resets, the outward movement of the LED module unit 200 driven by the reset of the adjusting assembly 400, the outward movement of the LED module unit 200 drives the combination head 305 to move through the sliding column 303, the combination head 305 first contacts the guide head 304, the limiting guide block 308 contacts the outside of the combination head 305 and cannot limit the position of the limiting guide block 308, so that the limiting guide block 308 moves under the combination of the combination head 305 and the guide head 304, so that the combination head 305 and the guide head 304 move out of the limiting guide block 308, and then the damaged LED module unit 200 is disassembled.

[0037] Please refer to Figure 7 and Figure 8 The replacement assembly 300 further comprises an auxiliary plate 3012 fixed at the end of the sliding rod 309, the auxiliary plate 3012 is made of high-strength material, for example, can be made of high-strength plastic, the auxiliary plate 3012 can slide on the sliding sleeve 307, and the end of the auxiliary plate 3012 slides and contacts the adjusting assembly 400.

[0038] When disassembled, the sliding rod 309 moves outward in the sliding sleeve 307, which drives the auxiliary plate 3012 to move towards the adjusting assembly 400, thereby isolating the adjusting assembly 400 from the LED module unit 200, facilitating better disassembly.

[0039] Please refer to Figure 2 , Figure 6 , Figure 7 and Figure 8 The replacement assembly 300 further comprises a mounting seat 3013 fixed between the mounting frame 100 and the base 301, which is suggested to have a square structure for facilitating the butt joint of the butt joint rods 3016.

The mounting seat 3013 is slidingly connected with the butt joint rods 3016 at the four corners. The butt joint rods 3016 in close proximity to each other are in contact with each other and can also be connected by a joint. The butt joint rods 3016 are in contact with the outer side of the receiving head 3014, and the elastic member 3017 is connected between the outer side of the middle of the butt joint rods 3016 and the inner side of the mounting seat 3013. The elastic member 3017 here is a spring.

[0040] During installation, the butt joint rods 3016 in close proximity to each other are in contact and abut each other, and can also be connected by a joint. The receiving head 3014 can elastically support the guide head 304 after installation, so that the guide head 304 tightly fits and clamps the limiting guide block 308. During disassembly, the guide head 304 will press the receiving head 3014, and the receiving head 3014 will move with it. The movement of the receiving head 3014 will extrude the butt joint rods 3016 to slide outward, and the elastic member 3017 will be stretched and deformed. The outward sliding of the butt joint rods 3016 will extrude the butt joint rods 3016 on the adjacent LED module unit 200. The adjacent butt joint rods 3016 will extrude the receiving head 3014, and the receiving head 3014 will extrude the guide head 304, so that the guide head 304 tightly fits and clamps the limiting guide block 308, preventing the surrounding from being affected and loosening during disassembly.

[0042] In use, the screw rod 402 is threadedly rotated on the nut 403, the nut 403 cannot be rotated due to the cooperation of the limiting slot and the limiting slide rod, so that the whole is lengthened or shortened in the telescopic sleeve 401 when the screw rod 402 is rotated, and the screw rod 402 drives the nut 403 to slide back and forth on the telescopic sleeve 401 through the cooperation of the limiting slot and the limiting slide rod, and the separation structure keeps the telescopic sleeve 401 and the screw rod 402 in a separated state.

[0043] Please refer to Figure 2 , Figure 7 and Figure 8 , the separation structure comprises a magnet I 404 fixed on the end portion of the screw rod 402 and a magnet II 405 on the inner side end portion of the telescopic sleeve 401, the opposite faces of the magnet I 404 and the magnet II 405 have the same magnetism, and a magnetic separation sleeve can be added to the outer side of the telescopic sleeve 401 to prevent the components near the magnetization.
