[0024] In this embodiment, as shown in Figure 3 Figure 7 As shown, the wireless controller 18 is located on one side of the linear rudder 9, and the bus controller 18 is fixedly connected between the shell 3; the upper side of the wireless controller 18 is provided with a GPS sensor 20, and the GPS sensor 20 is fixedly connected with the wireless controller 18.

When the lamp shell 1 is stolen and moved, the lamp shell 1 drives the shell 3 to move, and the shell 3 drives the bus controller 18 to move, so that the GPS sensor 20 moves. When the GPS sensor 20 senses that the position value changes, the linear rudder 9 can be immediately started through the wireless controller 18, and the shape light spot is immediately adjusted to the anti-theft state.
[0025] In this embodiment, as shown in the figure, Figure 8 As shown, the outer ring 21 is fixedly connected between the lamp bead 2 and the lamp shell 1, the inner wall of the outer ring 21 is threadedly connected with the transparent cover 23, and the projection sheet 22 is placed between the transparent cover 23 and the outer ring 21. A plurality of hollow light spots 26 are formed on one side of the projection sheet 22, and the transparent cover 23 is in abutting connection with the projection sheet 22. In order to illuminate the projection sheet 22 after the lamp bead 2 is powered, the transparent cover 23 and the outer ring 21 are threadedly engaged to provide an abutting force to the projection sheet 22, and the lamp bead 2 illuminates the hollow light spot 26 to generate a shape light spot, which is transparently irradiated through the transparent cover 23, so that the light spot projection illumination can be realized.
[0026] In this embodiment, as shown in the figure, Figure 1 As shown, the outer ring 21 is fixedly connected between the lamp bead 2 and the lamp shell 1, the inner wall of the outer ring 21 is threadedly connected with the transparent cover 23, and the projection sheet 22 is placed between the transparent cover 23 and the outer ring 21. A plurality of hollow light spots 26 are formed on one side of the projection sheet 22, and the transparent cover 23 is in abutting connection with the projection sheet 22. In order to illuminate the projection sheet 22 after the lamp bead 2 is powered, the transparent cover 23 and the outer ring 21 are threadedly engaged to provide an abutting force to the projection sheet 22, and the lamp bead 2 illuminates the hollow light spot 26 to generate a shape light spot, which is transparently irradiated through the transparent cover 23, so that the light spot projection illumination can be realized.
[0027] The use process of the light spot adjustable projection lamp is as follows: Firstly, during installation and use of the present application, the holes of the mounting disc 25 are inserted by bolts, so that the mounting disc 25 is fixed on the mounting table, and the mounting disc 25 supports the mounting frame 24, and the mounting frame 24 supports the lamp shell 1, thereby increasing the stability of the lamp shell 1 during use. At the same time, the GPS sensor 20 records the installation position data. The lamp bead 2 is connected with an external power supply, and the lamp bead 2 illuminates the projection sheet 22 after being powered, and the transparent cover 23 and the outer ring 21 are threadedly engaged to provide an abutting force to the projection sheet 22, so that the lamp bead 2 stably illuminates the projection sheet 22, and the hollow light spot 26 generates a shape light spot, which is transparently irradiated through the transparent cover 23, and then the shape light spot is transparently irradiated through the lens 17, and the shape light spot is projected onto the illumination plane.
[0028] Secondly, when the theft person removes the bolt on the installation disc 25, the lamp shell 1 moves, the shell 3 moves, the bus controller 18 moves, the battery 19 moves, the GPS sensor 20 moves, and the wireless controller 18 is powered by the battery 19. When the GPS sensor 20 senses that the position value changes, the wireless controller 18 can immediately start the linear steering engine 9.
[0029] The output end of the linear steering engine 9 pushes the pressing strip 8 to move upwards, the pressing strip 8 moves upwards along the inner wall of the shell 3, the connecting pad 7 is pulled and stretched upwards by the pressing strip 8, the elastic pad 6 is pulled and stretched upwards by the connecting pad 7, and the shielding pad 5 is pulled and stretched upwards by the elastic pad 6. At the same time, the lamp shell 1 supports the shell 3, the shell 3 supports the arc-shaped strip 4, and the arc-shaped strip 4 provides firm support for the shielding pad 5. When the outer wall of the pressing strip 8 contacts the top position of the inner wall of the lamp shell 1, the connecting pad 7, the elastic pad 6 and the shielding pad 5 are in the circular space of the inner wall of the lamp shell 1. The outer walls of the shielding pad 5, the elastic pad 6 and the connecting pad 7 are all sprayed with a layer of black paint, which covers and shields the shape light spot on the right side of the lamp bead 2, so that when the theft person powers on the lamp bead 2, the shape light spot generated by the hollow light spot 26 is all irradiated on the covering and shielding area of the shielding pad 5, the elastic pad 6 and the connecting pad 7, so that the shape light spot is covered and shielded, and the shape light spot is adjusted to be in an unusable state.
[0030] Then, when the invention is stolen and limited, the pressing strip 8 moves upwards, the limiting strip 10 moves upwards synchronously, the limiting strip 10 is separated from the groove strip 11, and the limiting strip 10 no longer limits the groove strip 11. At the same time, the shell 3 supports the supporting strip 13, the supporting strip 13 supports the elastic sheet 12, and the elastic sheet 12 initially generates a pushing and extruding force on the groove strip 11. When the limiting strip 10 no longer contacts and limits the groove strip 11, the pushing and extruding force generated by the elastic sheet 12 drives the groove strip 11 to move to the right, the groove strip 11 drives the plug-in rod 14 to move to the right along the inner wall of the lamp shell 1, and the plug-in rod 14 moves to the right and is inserted into the groove body 16 in the mirror cover 15. In this way, the plug-in rod 14 limits and protects the mirror cover 15, so that the theft person cannot rotate the mirror cover 15 and separate it from the lamp shell 1, and the theft person cannot disassemble the mirror cover 15 and damage the shielding pad 5, the elastic pad 6 and the connecting pad 7, so as to ensure that the shape light spot is adjusted to be in an unusable state. The stolen lamp bead 2 cannot be used, the idea of the theft person to continue to steal other lamp beads 2 is broken, and the number of stolen and lost items is reduced.
[0031] Finally, when the invention is searched, the position value of the GPS sensor 20 is continuously transmitted to the background computer through the wireless controller 18, so that the stolen lamp bead 2 is located and found according to the position value of the GPS sensor 20, and the projection light spot is avoided from being used during the period of being stolen.

In the technical solution, the electric appliance control elements not mentioned belong to the prior art, and therefore are not shown in the drawings, and will not be described here.
[0033] The application has been described in detail above with general description and specific embodiments, but some modifications or improvements can be made on the basis of the application, which is obvious to the skilled in the art. Therefore, these modifications or improvements made on the basis of not deviating from the spirit of the application all belong to the scope of the application claimed.
