[0017] Reference Figures 1 to 11 A DC-plug-mounted, tilting, color-temperature adjustable spotlight includes: a mounting square tube 1, with at least two oblong holes 2 on its opening; the mounting square tube 1 needs to be fixed in a professional wall cabinet, and the spotlight on the mounting square tube 1 emits light to illuminate the exhibits in the professional wall cabinet; and mounting bases 3, at least two mounting bases 3 being detachably embedded in at least two oblong holes 2 on the mounting square tube 1. The mounting bases 3 are flat and inserted into the oblong holes 2 of the mounting square tube 1 to prevent the mounting bases 3 from rotating on the mounting square tube 1, and to position the circular lamp body 13 so as to facilitate adjustment of the light illumination position.

[0018] In this invention, a DC female socket 7 is threadedly embedded at one end of a mounting base 3. The DC female socket 7 is installed by threaded engagement with the mounting base 3, providing a secure fit without the need for adhesive. A threaded cylinder 8 is embedded at one end of the mounting base 3. A threaded tube 9 is threadedly fitted at one end of the threaded cylinder 8. The threaded cylinder 8 and the threaded tube 9 do not require adhesive for fixation. A hollow ball head 10 is integrally formed and fixed at the other end of the threaded tube 9. A threaded end cap 11 and a silicone ring 12 are movably fitted on the surface of the hollow ball head 10. The threaded end cap 11 is threadedly embedded at one end of the round lamp body 13. The threaded end cap 11 abuts against the surface of the silicone ring 12, pressing the silicone ring 12 against the surface of the hollow ball head 10. The surface of the silicone ring 12 rubs against the hollow ball head 10, which can position the hollow ball head 10 inside one end of the round lamp body 13.

[0019] In this invention, a circular lamp body 13 is movably fitted onto the surface of a hollow ball head 10 at one end. The hollow ball head 10 can rotate at one end of the circular lamp body 13, allowing adjustment of the angle between the axial direction of the circular lamp body 13 and the hollow ball head 10, as well as the angle of the circular lamp body 13 on the side of the mounting square tube 1. This facilitates adjustment of the direction of the light emitted by the circular lamp body 13 and the position of the light illumination. An intermediate plate is integrally formed and fixedly disposed in the middle of the inner wall of the circular lamp body 13. A dual-color LED light source board 14 is also included. The device is placed on the surface of the middle plate. The dual-color LED light source board 14 can be obtained by purchasing from the market or by private customization. The dual-color LED light source board 14 is provided with three solder points. Three welding wires are respectively soldered to the three solder points of the dual-color LED light source board 14. The other end of the three welding wires is soldered to the pin. The dual-color LED light source board 14 is connected to the power supply through the welding wires. One end of the three welding wires is connected to the dual-color LED light source board 14, and the other end of the three welding wires is connected to the outer tube 81, the middle tube 83 and the inner tube 85 respectively.

[0020] In this invention, the opening at the other end of the mounting base 3 is provided with multiple notches, and an elastic plate 5 is integrally formed and fixedly installed in the notch at the other end of the mounting base 3. A limit plate 4 is integrally formed and fixedly installed at the other end of the mounting base 3. A threaded sleeve 6 is integrally formed and fixedly installed on the inner wall of one end of the mounting base 3. A dual-color LED lamp bead 15 is fixedly installed on the top of the dual-color LED light source board 14. A high-transmittance lens 16 is detachably installed inside the round lamp body 13. A diffusion film is provided on the surface of the high-transmittance lens 16 to optimize the light pattern after LED light mixing. The high-transmittance lens 16 is equipped with a clamping cup bracket to improve reflectivity.

[0021] In this invention, a lens cap 18 is threaded onto the other end of the circular lamp body 13. One end of the circular lamp body 13 is inclined, which increases the heat dissipation area and makes the oscillation angle of the circular lamp body 13 larger. The circular lamp body 13 can be adjusted to 360 degrees. One end of the DC female socket 7 is integrally formed and fixedly provided with a threaded bolt 19. The other end of the DC female socket 7 is fixedly provided with multiple welding plates 17.

[0022] In this invention, the threaded bolt 19 at one end of the DC female socket 7 is threadedly embedded in the middle of the threaded sleeve 6. The side of the elastic plate 5 is provided with a protrusion, which abuts against the inner wall of the mounting square tube 1. The limiting plate 4 abuts against the surface of the mounting square tube 1, so that the mounting square tube 1 is clamped in the gap between the protrusion on the side of the elastic plate 5 and the limiting plate 4. The threaded tail cap 11 is threadedly embedded in one end of the round lamp body 13. The silicone ring 12 abuts against the gap between the threaded tail cap 11 and the round lamp body 13. Three welding lines move through the middle of the hollow ball head 10. The high-transmittance lens 16 has a non-planar structure, which can optimize the LED light mixing effect. The end of the high-transmittance lens 16 abuts against the end of the lens cover 18. The opening in the round lamp body 13 is provided with a connecting port, and the three welding lines move through the connecting port of the round lamp body 13.

[0023] In this invention, a insert pin is movably inserted through the center of the threaded cylinder 8. The insert pin includes: an outer wire cylinder 81, an outer insulating rubber 82, a middle wire cylinder 83, and an inner insulating rubber 84. The outer wire cylinder 81 is movably inserted through the center of the threaded cylinder 8. The outer insulating rubber 82 is disposed through the center of the outer wire cylinder 81. The outer insulating rubber 82 is an insulating material that can isolate current. The outer insulating rubber 82 separates the outer wire cylinder 81 and the middle wire cylinder 83 to prevent short circuits between them. The middle wire cylinder 83 is disposed through the center of the outer insulating rubber 82. The inner insulating rubber 84 is an insulating material that can isolate current. The outer insulating rubber 82 separates the inner wire cylinder 83 and the middle wire cylinder 84 to prevent short circuits between them. To prevent short circuits between the inner tube 85 and the middle tube 83, the inner tube 85 is inserted through the middle of the inner insulating rubber 84. Multiple rolling columns 86 are movably embedded around the inner wall of the threaded tube 8. The multiple rolling columns 86 abut against the surface of the outer tube 81, and a line contact is formed between the rolling columns 86 and the outer tube 81. Rolling friction is formed between the rolling columns 86 and the outer tube 81, reducing the resistance when the rolling columns 86 rotate. A magnetic ring 87 is glued to the other end of the threaded tube 8. A friction ring 88 is embedded at the bottom of the magnetic ring 87, and a line contact is formed between the friction ring 88 and the threaded tube 8, greatly reducing the contact area and preventing friction between the magnetic ring 87 and the threaded tube 8. This allows the magnetic ring 87 and the threaded tube 8 to rotate quickly and smoothly.

[0024] In this invention, a plurality of conductive blocks 71 are fixedly disposed on the inner wall of the DC female socket 7, a small spring 72 is fixedly disposed on the surface of the conductive block 71, a pressing block 73 is fixedly disposed on one end of the small spring 72, a plurality of conductive plates 74 are embedded in the bottom of the DC female socket 7, and the elastic force of the small spring 72 acts on the pressing block 73, so that the three pressing blocks 73 respectively press against the surface of the outer tube 81, the middle tube 83 and the inner tube 85.

[0025] In this invention, an outer tube 81, an outer insulating rubber 82, a middle tube 83, an inner insulating rubber 84, and an inner tube 85 are sequentially nested. The outer tube 81, outer insulating rubber 82, middle tube 83, inner insulating rubber 84, and inner tube 85 all movably pass through the middle of the threaded tube 8. Multiple rolling columns 86 abut against the outer outer surface of the outer tube 81. The threaded tube 8 is made of a magnetically conductive metal material that can be attracted by a magnetic ring. The threaded tube 8 can be attracted by a magnetic ring 87, so that the outer tube 81 always passes through the middle of the threaded tube 8.

[0026] In this invention, the conductive block 71, the small spring 72, and the pressing block 73 are all disposed in the notch opened in the inner wall of the DC female socket 7. One end of the multiple conductive plates 74 is respectively connected to the surface of the multiple conductive blocks 71, and the other end of the multiple conductive plates 74 is respectively connected to the surface of the multiple welding plates 17. The conductive block 71, the small spring 72, the pressing block 73, the conductive plate 74, the outer wire tube 81, the middle wire tube 83, and the inner wire tube 85 are all made of conductive material. The conductive block 71, the small spring 72, the pressing block 73, the conductive plate 74, the outer wire tube 81, the middle wire tube 83, and the inner wire tube 85 can form a current return flow to power the dual-color LED light source board 14.

[0027] In this invention, the bottom of the DC female socket 7 is provided with three welding plates 17, on which wires can be welded. The welding plates 17 are then wrapped with heat shrink tubing, and the three wires are passed through the mounting square tube 1. The three wires are connected to the low-voltage power supply for dimming and color adjustment, supplying power to the dual-color LED light source board 14 and the dual-color LED beads 15. The round lamp body 13 can be inserted into the mounting base 3 to supply power to the dual-color LED light source board 14 inside. When the round lamp body 13 is pulled out from the end of the mounting base 3, the power is automatically cut off. When the round lamp body 13 rotates, the pins are connected to the DC female socket 7, so that the power supply can continue. The mounting base 3 has an oblong structure. The mounting base 3 is inserted into the oblong hole 2 of the mounting square tube 1. The mounting base 3 is flat, and the shape of the oblong hole 2 matches the shape of the mounting base 3, which can effectively prevent the mounting base 3 and the round lamp body 13 from rotating together.

[0028] In this invention, the mounting base 3, DC female socket 7, threaded cylinder 8, and threaded tube 9 are all connected by threaded sleeves or detachable embedded connections, realizing modular assembly and convenient disassembly of the device.

[0029] During installation, firstly, one end of each of the three welding wires is welded to the three solder points on the dual-color LED light source board 14. Then, the other ends of the three welding wires are sequentially passed through the middle plate of the circular lamp body 13, the silicone ring 12, the threaded end cap 11, the hollow ball head 10, the threaded tube 9, and the threaded cylinder 8. Next, the other ends of the three welding wires are welded to the surfaces of the outer coil 81, the middle coil 83, and the inner coil 85, respectively. Then, the hollow ball head 10 is placed into the end of the circular lamp body 13. The threaded end cap 11 is then rotated and installed into the end of the circular lamp body 13, so that the silicone ring 12 is pressed against the surface of the hollow ball head 10 by the threaded end cap 11. Then, the outer coil 81, outer insulating glue 82, middle coil 83, inner insulating glue 84, and inner coil 85 are passed through the threaded cylinder 8, bringing the magnet ring 87 close to the threaded cylinder 8. The attraction between the threaded cylinder 8 and the magnet ring 87 causes the friction ring 88 to press against the threaded cylinder 8. At the top, the outer tube 81, outer insulating glue 82, middle tube 83, inner insulating glue 84, and inner tube 85 are fixed in the middle position of the threaded tube 8. Then, the threaded bolt 19 at the end of the DC female socket 7 is rotated and installed in the threaded sleeve 6 in the middle of the mounting base 3. Then, the mounting base 3 is inserted into the waist-shaped hole 2 of the mounting square tube 1. The mounting square tube 1 compresses the elastic plate 5 and deforms and shrinks, so that multiple elastic plates 5 pass through the waist-shaped hole 2. The limiting plate 4 and multiple elastic plates 5 respectively abut against the surface and inner wall of the mounting square tube 1. The mounting base 3 can be fixed in the waist-shaped hole 2 of the mounting square tube 1. Finally, the threaded tube 9 is rotated and sleeved on the threaded tube 8. During this process, the outer tube 81, outer insulating glue 82, middle tube 83, inner insulating glue 84, and inner tube 85 are inserted into the DC female socket 7. The three pressing blocks 73 abut against the surface of the outer tube 81, middle tube 83, and inner tube 85 respectively. In use, the three welding plates 17 are connected to the power supply. Current flows back through the structure formed by the conductive block 71, small spring 72, pressing block 73, conductive plate 74, outer wire tube 81, middle wire tube 83, and inner wire tube 85, and the current flows through the dual-color LED light source board 14. The dual-color LED beads 15 produce light, which can power and ground the dual-color LED light source board 14. At the same time, the circular lamp body 13 is rotated around the center of the hollow ball head 10, which can adjust the axial position of the circular lamp body 13 and change the illumination position of the light produced at the other end of the circular lamp body 13. The axial position of 3 rotates in the middle. During this process, the dual-color LED light source board 14 will rotate the three welding wires. The torque between the three welding wires will cause the outer wire tube 81, outer insulating glue 82, middle wire tube 83, inner insulating glue 84, inner wire tube 85, rolling column 86, magnet ring 87 and friction ring 88 to rotate. The three pressing blocks 73 always press against the outer wire tube 81, middle wire tube 83 and inner wire tube 85 respectively, so that the current return formed between the conductive block 71, small spring 72, pressing block 73, conductive plate 74, outer wire tube 81, middle wire tube 83 and inner wire tube 85 will not be interrupted due to their rotation.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
