[0023] The following description, in conjunction with the accompanying drawings, further illustrates the proposed solution:

[0024] Example 1

[0025] See appendix Figure 1-9 A lamp power connection structure that can rotate around a track includes a conductive rail 1, a conductive ring 2, a power connection base 3, and a top cover 4.

[0026] The conductive rail 1 includes a profile rail 11 and conductive wires mounted on the profile rail 11.

[0027] The conductive ring 2 includes a ring body, a conductive ring 2 rail, and a ring contact electrode; the conductive ring 2 rail is wrapped around the outside of the ring body, and the ring contact electrode is fixed to the conductive ring 2 rail and extends to the inside of the ring body; the conductive ring 2 is clamped on the conductive rail 1 and the ring contact electrode is in contact with the conductive wire to conduct electricity.

[0028] The electrical connector 3 is used for mounting on a lamp fixture, and the electrical connector 3 is provided with a lamp fixture electrode that is electrically connected to the light source of the lamp fixture. The light source is an LED light source 51. The lamp fixture electrode is electrically connected to the LED electrode via a wire 54.

[0029] The upper cover 4 is provided with a first half-hole portion 41, and the power base 3 is provided with a second half-hole portion 31. The upper cover 4 and the power base 3 are detachably connected. When the upper cover 4 and the power base 3 are connected, the first half-hole portion 41 and the second half-hole portion 31 form a connecting hole. The connecting hole is fitted around the conductive ring 2 and rotates with the conductive ring 2 so that the power base 3 and the upper cover 4 are rotatably mounted on the conductive ring 2. The lamp contact electrode is in contact with the conductive ring 2 rail and conducts electricity, and moves along the conductive ring 2 rail when the power base 3 rotates.

[0030] This technical solution involves setting a conductive ring 2 on the conductive rail 1, so that the lamp's contact socket 3 is electrically connected to the conductive rail 1, and the contact socket 3 can rotate relative to the conductive ring 2. During the rotation, the lamp's contact electrodes remain in contact with the conductive ring 2, thus enabling the lamp to rotate 360 ​​degrees on the conductive rail 1.

[0031] Specifically, the conductive wires include a positive conductive wire 12 and a negative conductive wire 13.

[0032] The conductive ring 2 includes a positive ring rail and a negative ring rail, and the ring contact electrode includes a positive ring contact 27 and a negative ring contact 28; the positive ring contact 27 is fixed to the positive ring rail and is in contact with the positive conductive wire 12 for conduction; the negative ring contact 28 is fixed to the negative ring rail and is in contact with the negative conductive wire 13 for conduction.

[0033] The lamp contact electrode includes a positive lamp contact 32 and a negative lamp contact 33; the positive lamp contact 32 is in contact with the positive electrode ring rail and conducts electricity; the negative lamp contact 33 is in contact with the negative electrode ring rail and conducts electricity.

[0034] like Figure 6 and Figure 7As shown, the ring body is formed by splicing a first half-ring 21 and a second half-ring 22; the positive electrode ring rail is formed by splicing a semi-annular first positive electrode ring rail 23 and a second positive electrode ring rail 24; the negative electrode ring rail is formed by splicing a semi-annular first negative electrode ring rail 25 and a second negative electrode ring rail 26; the first positive electrode ring rail 23 and the first negative electrode ring rail 25 are mounted on the first half-ring 21, specifically by screws; the second positive electrode ring rail 24 and the second negative electrode ring rail 26 are mounted on the second half-ring 22, specifically by screws; the first half-ring 21 and the second half-ring 22 are detachably connected. The first half-ring 21 and the second half-ring 22 are provided with annular grooves 20 for mounting the positive and negative electrode ring rails.

[0035] This technical solution divides the conductive ring 2 into two parts for splicing and assembly, which facilitates production and installation in conjunction with the conductive rail 1.

[0036] The ring contact positive electrode 27 is fixedly connected to the first positive electrode ring rail 23; the ring contact negative electrode 28 is fixedly connected to the second negative electrode ring rail 26; the lamp contact positive electrode 32 includes two electrodes, and the two lamp contact positive electrodes 32 are symmetrically arranged in the second half-hole portion 31; one lamp contact positive electrode 32 is in contact with the first positive electrode ring rail 23, and the other lamp contact positive electrode 32 is in contact with the second positive electrode ring rail 24, as shown. Figure 3 As shown; similarly, the lamp contact negative electrode 33 includes two, and the two lamp contact negative electrodes 33 are symmetrically arranged in the second half hole 31; one lamp contact negative electrode 33 is in contact with the first negative electrode ring rail 25, and the other lamp contact negative electrode 33 is in contact with the second negative electrode ring rail 26.

[0037] In this technical solution, the positive electrodes 32 of the lamp are arranged in pairs symmetrically. No matter how much the junction box 3 is rotated, there will always be one positive electrode 32 of the lamp in contact with the first positive electrode ring rail 23, that is, connected with the ring positive electrode 27 and the positive electrode conductive wire 12. Even if there is no electrical contact between the first positive electrode ring rail 23 and the second positive electrode ring rail 24 due to the splicing gap, it will not affect the lamp's electrical connection structure.

[0038] Similarly, the negative terminals 33 of the lamp contacts are arranged symmetrically in pairs, and one of the negative terminals 33 of the lamp contacts is always in contact with the second negative terminal ring 26, that is, connected to the ring negative terminal 28 and the negative conductive wire 13. Even if there is no electrical contact between the first negative terminal ring 25 and the second negative terminal ring 26 due to the splicing gap, it will not affect the lamp's electrical connection structure.

[0039] like Figure 4 and Figure 5As shown, the profile track 11 has a first groove 111 and a second groove 112 extending along its length on both sides. The positive conductive wire 12 is installed in the first groove 111 and the negative conductive wire 13 is installed in the second groove 112.

[0040] The first semi-ring 21 has a first limiting protrusion 211 on its inner side, and the first semi-ring 21 has a first through hole 212 that extends from its outer side to the first limiting protrusion 211. The ring contact positive electrode 27 passes through the first through hole 212 to the inner side of the first semi-ring 21. The first limiting protrusion 211 falls into the first wire groove 111 to restrict the first semi-ring 21 from rotating circumferentially relative to the profile track 11. The first limiting protrusion 211 has an arc surface that fits with the positive conductive wire 12.

[0041] The second semi-ring 22 has a second limiting protrusion 221 on its inner side, and a second through hole 222 extending from its outer side to the second limiting protrusion 221. The ring contact negative electrode 28 passes through the second through hole 222 to the inner side of the second semi-ring 22. The second limiting protrusion 221 falls into the second wire groove 112 to restrict the second semi-ring 22 from rotating circumferentially relative to the profile track 11. The second limiting protrusion 221 has an arc surface that fits with the negative conductive wire 13.

[0042] In this technical solution, the conductive ring 2 is engaged with the first wire groove 111 by the first limiting protrusion 211 and with the second wire groove 112 by the second limiting protrusion 221, which restricts the circumferential rotation of the ring body relative to the profile track 11, so that the conductive ring 2 is circumferentially fixed relative to the conductive rail 1, preventing the conductive ring 2 from rotating when the lamp rotates, and ensuring the stability of the electric contact with the conductive wire.

[0043] The ring contact electrode is needle-shaped. In this embodiment, the positive electrode 27 of the ring contact is welded and fixed to the first positive electrode ring rail 23, and its tip is in contact with the positive electrode conductive wire 12 for conduction; the negative electrode 28 of the ring contact is welded and fixed to the second negative electrode ring rail 26, and its tip is in contact with the negative electrode conductive wire 13 for conduction.

[0044] The lamp contact electrode is a conductive spring pin, which makes elastic contact with the conductive ring 2 rail, facilitating the rotation of the lamp relative to the conductive ring 2; and generates a damping force with the conductive ring 2 rail, which can fix the angle of the lamp after rotation.

[0045] A detachable buckle structure is provided between the upper cover 4 and the power base 3; the buckle structure includes a buckle part on the power base 3 and a hanging part on the upper cover 4, and the buckle part is hooked on the hanging part.

[0046] In this embodiment, the latching part includes an elastic arm 34 erected on the power base 3 and a latching protrusion 341 located at the upper end of the elastic arm 34. The hooking part is a latching hole 42 provided on the upper cover 4. The latching protrusion 341 falls into the latching hole 42 and hooks onto the hole wall of the latching hole 42.

[0047] In this technical solution, the top cover 4 and the electrical connector 3 are detachably connected by a snap-fit ​​structure, which facilitates installation and disassembly.

[0048] The first half-ring 21 and the second half-ring 22 are provided with a plug-in joint and a socket.

[0049] like Figure 7 and Figure 8 As shown, in this embodiment, the first half-ring 21 is provided with a first insertion post 213, the second half-ring 22 is provided with a first insertion hole 223 opposite to the first insertion post 213, the second half-ring 22 is provided with a second insertion post 224, and the first half-ring 21 is provided with a second insertion hole 214 opposite to the second insertion post 224.

[0050] The first half-ring 21 and the second half-ring 22 of this technical solution are detachably connected by a plug-in method, and the disassembly and assembly operations are simple and easy to implement.

[0051] The two ends of the connecting hole are provided with limiting ribs 35, and the conductive ring 2 is located between the two limiting ribs 35.

[0052] In this technical solution, the conductive ring 2 is located between the limiting ribs 35 at both ends of the connecting hole, which prevents the axial position of the conductive ring 2 from shifting when the contact base 3 rotates, so that the lamp contact electrode remains on the track of the conductive ring 2 and ensures the stability of the contact.

[0053] Example 2

[0054] See Figure 10-11 A track-rotating lamp includes a lamp body 5 and a lamp power connection structure that can rotate around a track as described in Embodiment 1 above.

[0055] The power connector 3 is installed on the lamp body 5; the lamp body 5 is provided with an LED light source 51, the LED light source 51 is provided with an LED power electrode, and the lamp contact electrode is electrically connected to the LED power electrode through a wire 54.

[0056] In this embodiment, the LED electrode includes an LED positive electrode 52 and an LED negative electrode 53;

[0057] The two lamp contact positive terminals 32 are connected in parallel through wire 54 and then electrically connected to the LED contact positive terminal 52; the two lamp contact negative terminals 33 are connected in parallel through wire 54 and then electrically connected to the LED contact negative terminal 53.

[0058] The lamp body 5 includes a lampshade 55, which is connected to the power socket 3.

[0059] Example 3

[0060] like Figure 12-17 As shown, a track-rotating lamp differs from the second embodiment described above in that:

[0061] The shapes of the power connector 3, the top cover 4, and the lamp body 5 in this embodiment are different from those in Embodiment 1.

[0062] In this embodiment, a swing mechanism is provided between the power base 3 and the lamp body 5, which allows the lamp body 5 to swing relative to the power base 3. The swing mechanism includes a swing shaft 36 provided on the power base 3 and a swing seat 56 provided on the lamp body 5. The swing seat 56 is provided with a shaft hole 561, which is fitted onto the swing shaft 36 and rotates with the swing shaft 36.

[0063] This technical solution incorporates a swing mechanism between the power connector 3 and the lamp body 5 to increase the lamp angle adjustment range and meet the needs of different application scenarios.

[0064] The above preferred embodiments should be regarded as illustrative examples of the embodiments of the present application. Any technical deductions, substitutions, improvements, etc. that are similar to or based on the present application should be considered within the scope of protection of this patent.
