[0025] Further Figure 4 As shown, it is worth mentioning that sliding grooves 103 and connecting holes 102 are provided inside both sides of the frame 1, and the upper ends of the symmetrical connecting shafts 8 are slidably connected to the connecting holes 102 and fixedly connected to the connecting plates 801, and the upper ends of the connecting plates 801 are fixedly connected to the symmetrical second springs 802, and the upper ends of the symmetrical second springs 802 are fixedly connected to the upper ends of the sliding grooves 103. Through the sliding grooves 103 and the connecting holes 102, the positions and movement trajectories of the symmetrical connecting shafts 8 or several symmetrical second springs 802 are limited, thereby increasing the stability of the protective shell 5 when it moves up and down, and through the symmetrical second springs 802, the movement of the protective shell 5 can be made to have a certain thrust, and the position of the protective shell 5 is limited.

[0026] Further Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the symmetrical protrusion guides 501 are fixedly connected to one side of the lower end of both sides of the frame 1, and a limiting hole 5011 is provided in the middle of the symmetrical protrusion guide 501. The symmetrical protrusion guides 501 and the limiting hole 5011 in the middle thereof are respectively fitted and slidably connected to the outer surface of the first groove 603 or one end of the limiting shaft 608, thereby facilitating the installation and disassembly of the connecting shaft 8 or the protective shell 5.

[0027] This solution has the following working process: when the high-power LED spotlight with high heat dissipation is needed, first push the slider 605 that is slidably connected in the second groove 604 of the fixing device 6. At this time, the slider 605 moves backward, thereby causing the limiting shaft 608 to move backward, even if the protruding guide 501 can be separated from the limiting shaft 608. When the two are separated, a number of symmetrical second springs 802 will push the connecting plate 801 to move downward, that is, push the connecting shaft 8 and the protective shell 5 to the lowest end. At this time, the lower end outer surfaces of a number of heat sinks 9 are directly connected to the air. When the high-power LED spotlight with high heat dissipation is used up, the protective shell 5 can be fixedly connected to the lower end of the frame 1 by performing the above-mentioned reverse operations.

[0028] According to the above working process, it can be known that: through the sliding groove 103 and the connecting hole 102, the position and movement trajectory of the symmetrical connecting shaft 8 or several symmetrical second springs 802 are limited, thereby increasing the stability of the protective shell 5 when moving up and down, and through the symmetrical second spring 802, the movement of the protective shell 5 can be used with a certain thrust, and the position of the protective shell 5 is limited.

Through the guide hole 502, the protective shell 5 can always be kept in a dry state, thereby protecting the lower ends of several heat sinks 9.

A through hole 609 is horizontally opened, and one side of the slider 605 is fixedly connected to a first spring 606, and the other end of the first spring 606 is fixedly connected to the through hole. A limiting shaft 608 is fixedly connected to one side of the through hole 609 and the other side of the slider 605. The limiting shaft 608 can be slidably connected to the other side of the through hole 609, and the upper end of the slider 605 is provided with an anti-slip groove 607. Through the symmetrical fixing device 6, that is, by moving the slider 605 of the fixing device 6, the position of the limiting shaft 608 can be moved, that is, the mutual installation and disassembly of the connecting shaft 8 and the connecting block 601 of the fixing device 6 can be facilitated, thereby increasing the protection of the heat sink 9 when the device is not in use, thereby increasing the service life of the high-power LED projection lamp with high heat dissipation.

[0031] Further Figure 2 As shown, it is worth explaining in detail that the lower ends of several heat sinks 9 are all slidably connected to the partition 11 and extend a certain distance. Through the positions of several heat sinks 9, the heat dissipation efficiency of the heat sink 9 of the high-power LED projection lamp with high heat dissipation can be increased.

[0032] Further Figure 2As shown, it is worth specifically explaining that a plurality of first heat-conducting grooves 101 in the same direction as the plurality of heat sinks 9 are provided on the rear side of the frame 1, and a plurality of second heat-conducting grooves 1001 perpendicular to the first heat-conducting grooves 101 are provided on one side of the rear shell 10, and arc-shaped baffles 1002 are fixedly connected to the upper ends of the plurality of second heat-conducting grooves 1001.

[0034] In summary: when it is necessary to use the high-power LED projection lamp with high heat dissipation, first push the slider 605 slidingly connected in the second groove 604 of the fixing device 6. At this time, the slider 605 moves backward, thereby moving the limit shaft 608 backward, even if the protruding guide 501 can be separated from the limit shaft 608. When the two are separated, a number of symmetrical second springs 802 will push the connecting plate 801 to move downward, that is, push the connecting shaft 8 and the protective shell 5 to the lowest end. At this time, the lower end outer surfaces of a number of heat sinks 9 are directly connected to the air. After the high-power LED projection lamp with high heat dissipation is used up, the protective shell 5 can be fixedly connected to the lower end of the frame 1 by following the above-mentioned reverse operation. Through the symmetrical fixing device 6, that is, by moving the slider 605 of the fixing device 6, the position of the limit shaft 608 can be moved, that is, The mutual installation and disassembly of the connecting shaft 8 and the connecting block 601 of the fixing device 6 can be facilitated, thereby increasing the protection of the heat sink 9 when the device is not in use, thereby increasing the service life of the high-power LED projection lamp with high heat dissipation. The heat dissipation efficiency of the heat sink 9 of the high-power LED projection lamp with high heat dissipation can be increased through the positions of the heat sinks 9. The heat dissipation effect of the upper ends of the heat sinks 9 is facilitated through the first heat conduction groove 101 at the rear end of the frame 1 and the second heat conduction groove 1001 on the side of the rear shell 10, and the baffle 1002 at the upper end of the second heat conduction groove 1001 can prevent rainwater from entering the interior of the device, thereby having a certain impact on the operation of the LED lamp. Through the guide hole 502, the protective shell 5 can always be kept in a dry state, thereby protecting the lower ends of the heat sinks 9.
