[0029] Reference Figure 1-3 , Figure 1 is a schematic diagram of the structure of the extendable LED lamp in the retracted state in the embodiment, Figure 2 is a schematic diagram of the structure of the extendable LED lamp in the extended state in the embodiment, Figure 3 for Figure 2 In the enlarged view of part A, the extendable LED lamp structure in this embodiment includes a lamp body 1, a power supply 2 and an extension 3. The lamp body 1 includes an optical component 11 and a lamp housing 12, and the optical component 11 is arranged in the lamp housing 12. The power supply 2 is arranged in the lamp housing 12, and the power supply 2 is electrically connected to the optical component 11. One end of the power supply 2 is connected to a wiring harness, and the end of the wiring harness away from the power supply 2 extends toward the outside of the lamp housing 12. The extension 3 is movably arranged at one end of the lamp housing 12. In the retracted state, the extension 3 is located in the lamp housing 12. In the extended state, the extension 3 extends toward the outside of the lamp housing 12, and the part of the wiring harness located outside the lamp housing 12 is accommodated in the extension 3.

[0030] Refer to Figure 4 , Figure 4It is a schematic diagram of the local structure of the linear lamp in the embodiment. Since the end of the wiring harness group away from the power supply unit 2 needs to extend toward the outside of the lamp housing 12 to connect to the AC power, the extension member 3 is arranged to push the extension member 3 to extend relative to the lamp housing 12, and form a wiring harness accommodating space outside the lamp housing 12, and accommodate the wiring harness group exposed outside the lamp housing 12 in the wiring harness accommodating space. This can not only effectively protect the part of the wiring harness group exposed outside the lamp housing 12, avoiding damage to the wiring harness group during use and accidents caused by accidental touch, but also shield the wiring harness group to avoid the wiring harness being exposed outside the lamp housing 12 in a disorderly manner, thereby improving the user's perception and usage experience. Specifically, the extendable LED lamp structure in the present embodiment can be applied to linear lamps, which include at least one extendable LED lamp structure. In the present embodiment, a linear lamp composed of two extendable LED lamp structures is introduced. The extendable LED lamp structure in the present embodiment is a long linear structure. The two extendable LED lamp structures are arranged adjacent to each other, and the two extendable LED lamp structures are arranged in a linear arrangement. There is a spacing space between the two extendable LED lamp structures to reserve a position for the AC power interface. The extension piece 3 is located between the two adjacent extendable LED lamp structures. It can be understood that when the extension piece 3 is extended relative to the lamp housing 12, one end of the extension piece 3 is connected to the lamp housing 12, and the other end of the extension piece 3 is in contact with the adjacent extendable LED lamp structure, and the exposed parts of the wiring harness group are all accommodated in the extension piece 3.

[0031] Preferably, along the length direction of the lamp housing 12, the side of the lamp housing 12 is provided with a limiting sliding groove 121, and the extension member 3 is slidably connected in the limiting sliding groove 121. In specific applications, the optical member 11 includes an LED lamp and an optical element, wherein the optical element can be an optical lens or a PC cover, etc., which is not limited here. The LED lamp is electrically connected to the power supply 2, and the optical lens or the PC cover is arranged outside the LED lamp. The LED lamp is a strip-shaped lamp, and the lamp housing 12 is also strip-shaped. Along the length direction of the lamp housing 12, the optical component 11 is arranged on one side of the lamp housing 12, and the limiting sliding groove 121 is arranged on the other side of the lamp housing 12. In this embodiment, the number of the limiting sliding grooves 121 is two, and the two limiting sliding grooves 121 are respectively arranged on the two side edges of the other side of the lamp housing 12. The two side edges of the extension member 3 are respectively slidably connected to the two limiting sliding grooves 121, and the side edges of the extension member 3 are adapted to the shape of the limiting sliding grooves 121, so that when the extension member 3 slides in the limiting sliding grooves 121, there is no deviation perpendicular to the length direction of the lamp housing 12, thereby improving the stability of the movement of the extension member 3.

[0032] Re-reference Figure 1-4Preferably, the extension member 3 includes an extension shell 31 and a positioning portion 32. The extension shell 31 is slidably connected in the limiting sliding groove 121. The positioning portion 32 is provided at one end of the lamp housing 12, and the positioning end of the positioning portion 32 abuts against the extension shell 31. Through the provision of the positioning portion 32, after the extension shell 31 is extended and moved to a specified position, the positioning portion 32 fixes the position of the extension shell 31, so that the extension shell 31 can be stably positioned at the specified position, so that after the extension shell 31 extends out of the lamp housing 12, the wiring harness group can be accommodated in the extension shell 31. Specifically, the extension shell 31 includes an extension shell body and two extension blocks. The two extension blocks are respectively arranged on both side edges of the extension shell body, and the two extension blocks extend in a direction away from the lamp housing 12. The shape of the extension block is adapted to the limiting sliding groove 121, that is, it fits with the groove wall of the limiting sliding groove 121 to prevent the extension shell 31 from shaking when moving. At the same time, the extension shell body and the two extension blocks also substantially form a wiring harness accommodating space, and the wiring harness group can be accommodated in the space.

[0033] Re-reference Figure 1-4Preferably, the positioning portion 32 includes a positioning bar 321 and a positioning spring 322. The positioning bar 321 is provided at one end of the lamp housing 12. The positioning bar 321 is provided with a plurality of positioning grooves 3211 along the length direction of the lamp housing 12. One end of the positioning spring 322 is provided at the extension shell 31, and the other end of the positioning spring 322 extends into one of the positioning grooves 3211. When the extension shell 31 is moved, the other end of the positioning spring 322 passes through the plurality of positioning grooves 3211 in sequence. When the extension shell 31 stops moving, the other end of the positioning spring 322 extends into one of the positioning grooves 3211 to fix the positions of the positioning spring 322 and the extension shell 31. In specific applications, one end of the positioning spring 322 is fixedly connected to the extension shell 31. By extending the other end of the positioning spring 322 into one of the positioning grooves 3211, the extension shell 31 can be positioned and fixed at the position corresponding to the positioning groove 3211, thereby adjusting the extension length of the extension shell 31. Specifically, the positioning groove 3211 is a V-shaped groove, and the positioning spring piece 322 is a V-shaped spring piece. It can be understood that since one end of the positioning spring piece 322 is fixedly connected to the extension shell 31, and one end of the positioning spring piece 322 is located at a position closer to the end of the extension shell 31, and the other end of the positioning spring piece 322 is located at a position closer to the inside of the extension shell 31, the other end of the positioning spring piece 322 is a movable end. In this way, when the extension shell 31 is extended outward from the lamp housing 12, the groove wall of the positioning groove 3211 will push the other end of the positioning spring 322, so that it can pass through multiple positioning grooves 3211 in sequence, that is, move from one positioning groove 3211 to the next adjacent positioning groove 3211. When the extension shell 31 needs to be pushed back into the lamp housing 12, the positioning groove 3211 will clamp the other end of the positioning spring 322, so that it cannot move to the next adjacent positioning groove 3211, that is, the extension shell 31 can be easily pushed to extend, but it is more difficult to retract, thereby improving the stability of the extension state of the extension shell 31. Of course, if the extension shell 31 needs to be retracted, it is only necessary to manually move the positioning spring 322 to make it leave the positioning groove 3211, and the extension shell 31 can be easily pushed to retract.

[0034] Re-reference Figure 1-4 Preferably, a stopper 3212 is provided at one end of the positioning bar 321, and the stopper 3212 is located at the end of the moving track of the positioning spring piece 322. By setting the stopper 3212, the positioning spring piece 322 can be blocked, that is, the extension shell 31 can be blocked, so as to prevent the extension shell 31 from excessively extending out of the lamp housing 12 and causing the extension shell 31 to separate from the lamp housing 12, thereby improving the stability of the extension structure. Specifically, the stopper 3212 is provided at one end of the positioning bar 321, and is located at a position close to the end of the lamp housing 12.

[0035] Re-reference Figure 1-4Preferably, the width of the extension shell 31 is smaller than the width of the lamp housing 12. In specific applications, the width of the extension shell 31 is slightly smaller than the width of the lamp housing 12. On the one hand, in the retracted state, the extension shell 31 is located in the lamp housing 12 and is in close contact with the groove wall of the limiting sliding groove 121, ensuring that the extension shell 31 does not shake. On the other hand, in the extended state, after the extension shell 31 extends out of the lamp housing 12, since the width of the extension shell 31 is slightly smaller than the width of the lamp housing 12, that is, slightly smaller than the width of the optical component 11, when the extendable LED lamp structure is installed and used, the extension shell 31 and the lamp housing 12 look similar when the user observes from a normal distance, which improves the user's perception and use experience. Furthermore, the color of the extension shell 31 is the same as the color of the lamp housing 12, which can further improve the integrity of the extendable LED lamp structure and further improve the user's perception and use experience.

[0036] Re-reference Figure 1-4 Preferably, there are two extension pieces 3, and the two extension pieces 3 are movably disposed at the two ends of the lamp housing 12. The extendable LED lamp structure in this embodiment is used as a linear lamp composed of multiple extendable LED lamp structures in a specific application. After extension, the extension piece 3 can fit with the lamp housing 12 of the adjacent extendable LED lamp structure, thereby improving the integrity of the linear lamp and the user experience. When one of the extendable LED lamp structures is close to a wall, the extension piece 3 at the other end of the lamp housing 12 can be extended to fit with the wall, which not only protects the wiring harness group, but also improves the user experience.

[0037] Refer to Figure 5-6 , Figure 5 is a schematic diagram of the structure of the electrical connector in the embodiment, Figure 61 is another structural schematic diagram of the electrical connector in the embodiment. Preferably, the extendable LED lamp structure further includes an electrical connector 4, which is disposed in the lamp housing 12. The wiring harness group includes a first wiring harness and a second wiring harness. The two ends of the first wiring harness are respectively connected to the power supply 2 and one end of the electrical connector 4, one end of the second wiring harness is connected to the other end of the electrical connector 4, and the other end of the second wiring harness extends out of the lamp housing 12. In specific applications, one end of the electrical connector 4 is provided with a plurality of phase-changing ports 41, and the other end of the electrical connector 4 is provided with a plurality of mounting ports 42. The second wiring harness has a plurality of circuits, and the plurality of circuits are respectively disposed in the electrical connector 4 through a plurality of mounting ports 42. One end of the first wiring harness is electrically connected to the power supply 2, and the other end of the first wiring harness is respectively connected to the corresponding circuits through a plurality of phase-changing ports 41. It can be understood that one end of the second wiring harness is connected to the mains, and the other end is connected to the electrical connector 4 through multiple installation ports 42. One end of the first wiring harness is electrically connected to the power supply 2, and the other end is connected to the electrical connector 4 through multiple phase-changing ports 41. In this embodiment, the mains is three-phase electricity, and the second wiring harness is correspondingly provided with three phase wire harnesses and multiple non-phase wire harnesses. Through the setting of the electrical connector 4, it is equivalent to a power phase-changing connector. By changing the connection state of the second wiring harness and the first wiring harness, three-phase power phase-changing can be achieved, that is, by selecting to connect with one of the phase wire harnesses, the phase line can be selected for power supply. Furthermore, the extendable LED lamp structure also includes a plurality of wiring harness fixings 5, and the plurality of wiring harness fixings 5 ​​are respectively arranged in the lamp housing 12, and are used to store and fix the wiring harness located in the lamp housing 12 to avoid the internal wiring harness from being entangled and causing safety hazards. Specifically, the wiring harness fixing 5 is an existing snap-on storage structure, which will not be repeated here.

[0038] To summarize, by setting the extension piece, the extension piece is pushed to extend relative to the lamp housing, and a wiring harness accommodating space is formed outside the lamp housing, and the wiring harness group exposed outside the lamp housing is accommodated in the wiring harness accommodating space. This not only can effectively protect the part of the wiring harness group exposed outside the lamp housing, avoiding damage to the wiring harness group during use and accidents caused by accidental touch, but also can shield the wiring harness group, avoiding the wiring harness from being exposed outside the lamp housing in a disorderly manner, thereby improving the user's perception and usage experience.
