[0033] It should be noted that in this application, "down" refers to the direction of light emission, while "up" is the opposite of "down," that is, opposite to the direction of light emission.

[0034] Please refer to the following: Figures 1 to 4The present invention provides a lamp with an adjustable power cord. The lamp with an adjustable power cord includes a lamp housing 1 having a receiving cavity 103, a light source 6, a driver 3, and a terminal block 2 disposed within the receiving cavity 103. It also includes a connecting wire 4 disposed within the receiving cavity 103. The connecting wire 4 includes a connecting body 401 and connecting ends 402 located at both ends of the connecting body 401. The connecting ends 402 are used for electrical connection with the driver 3 or the terminal block 2. The middle area of ​​the connecting body 401 has a bent elastic telescopic portion 4011. The elastic telescopic portion 4011 has elastic deformation capability and is configured with a pre-tightening force to bring the two connecting ends 402 closer together. The elastic telescopic portion 4011 is used to adjust the length of the connecting body 401.

[0035] The lamp with an adjustable power cord provided by this utility model, compared with the prior art, has an elastic telescopic part 4011 in the middle of the connecting wire 4. The elastic telescopic part 4011 can adjust the length of the connecting body 401. During lamp assembly, the elastic telescopic part 4011 is pulled according to actual needs, lengthening the bent elastic telescopic part 4011, so that the connecting end 402 can be electrically connected to the driver 3 or the terminal 2. At this time, the two connecting ends 402 are brought closer to each other under the elastic force of the elastic telescopic part 4011. The elastic telescopic part 4011 is stretched but still retains its elasticity, avoiding the problem of the elastic telescopic part 4011 becoming entangled or squeezed. By setting the elastic telescopic part 4011 with elastic deformation capability to adjust the length of the connecting body 401, this utility model allows the connecting wire 4 to adjust its length independently, avoiding the problem of the pre-reserved length of the connecting wire 4 not being able to adapt to the distance between the driver 3 and the terminal 2, resulting in failure to conduct electricity or the problem of excess wire being squeezed and entangled, thus improving the convenience and safety of the lamp assembly process.

[0036] Optionally, the elastic extension part 4011 is spiral or wavy. When the elastic extension part 4011 is spiral, it forms a spring wire.

[0037] As another specific embodiment of the lamp with an adjustable power cord, the lamp with an adjustable power cord also includes a winding assembly disposed in the receiving cavity 103. The winding assembly includes a fixed plate, a drive shaft, and an elastic winding member. The fixed plate is disposed in the receiving cavity 103 and has a fixing hole. The drive shaft is inserted into the fixing hole and rotatably connected to the lamp holder 102. The elastic telescopic part 4011 is wrapped around the drive shaft and located on one side of the fixed plate. The elastic winding member is disposed on the other side of the fixed plate and connected to the drive shaft. The elastic winding member is configured with a preload force to cause the elastic telescopic part 4011 to be wound around the drive shaft.

[0038] When the length of the connecting wire 4 needs to be adjusted, pull the connecting wire 4 to overcome the elastic force of the elastic winding member. After connecting the connecting end 402 of the connecting wire 4 to the driver 3 and the power terminal respectively, the elastic telescopic part 4011 remains wound up to the drive shaft under the action of the elastic winding member, avoiding tangling or squeezing and ensuring the safety of the circuit.

[0039] Optionally, the resilient winding element is a coil spring.

[0040] In some embodiments, please refer to Figures 1 to 4 The lamp housing 1 includes a lamp holder 102 and a lamp shade 101 connected to the lamp holder 102. The lamp shade 101 and the lamp holder 102 together form a receiving cavity 103. The lamp with an adjustable power cord also includes a mounting member 5 disposed in the receiving cavity 103. The mounting member 5 is a telescopic member that extends and retracts in the vertical direction, and the mounting member 5 is also connected to the lamp shade 101 and the lamp holder 102 respectively.

[0041] In this embodiment, the lamp holder 102 and the lampshade 101 are detachably connected. During lamp installation, the lamp holder 102 is first connected to the mounting surface, and then the mounting component 5 is connected to both the lamp holder 102 and the lampshade 101. Because the mounting component 5 has elastic tension, it is stretched under the weight of the lampshade 101, creating a certain gap between the lamp holder 102 and the lampshade 101. Then, overcoming the elastic force of the mounting component 5, the lamp holder 102 and the lampshade 101 are connected. This embodiment connects the lamp holder 102 and the lampshade 101 via the mounting component 5. Even if the connection structure between the lamp holder 102 and the lampshade 101 fails, they can still be connected together via the mounting component 5, improving the strength and reliability of the connection between the lamp holder 102 and the lampshade 101 and enhancing the safety of the lamp during use.

[0042] Optionally, the mounting component 5 can be snapped, screwed, or hung onto the lamp holder 102 and the lamp cover 101, respectively.

[0043] Optionally, mounting component 5 can be a tension spring.

[0044] In some embodiments, please refer to Figures 1 to 4 The lamp holder 102 is provided with a fixing ring 1024 located in the receiving cavity 103. The mounting component 5 includes a mounting ring 502 and an elastic component 501. The mounting ring 502 is located in the receiving cavity 103 and connected to the lamp cover 101. The elastic component 501 has a hooking part at each end. One hooking part is hooked to the fixing ring 1024 and the other hooking part is hooked to the mounting ring 502. The elastic component 501 is configured with a pre-tightening force to bring the lamp holder 102 and the lamp cover 101 closer to each other.

[0045] The mounting ring 502 is connected to the lampshade 101. The lamp holder 102 has a fixing ring 1024. One of the hook parts of the elastic member 501 is connected to the fixing ring 1024, and the other hook part is connected to the lampshade 101. The hook structure is easy to install and has a simple structure, avoiding occupying too much space in the receiving cavity 103, and is also inexpensive. When the lamp holder 102 is connected to the lampshade 101, the elastic member 501 is in a compressed state. When the lamp holder 102 and the lampshade 101 are opened, the elastic force of the elastic member 501 keeps the lampshade 101 close to the side of the lamp holder 102, preventing the lampshade 101 from completely separating from the lamp holder 102, thus improving the reliability and safety of the connection.

[0046] Optionally, the elastic component 501 can be a spring or a tension spring.

[0047] In some embodiments, please refer to Figures 1 to 4 The lampshade 101 has a connection hole, and the mounting ring 502 has a connection part that is inserted into the connection hole.

[0048] The connecting part of the mounting ring 502 is inserted into the connecting hole to connect with the lamp holder 102, eliminating the need for external connecting parts, simplifying the installation process and improving installation efficiency. Furthermore, the plug-in method allows for radial restraint of the connecting part, increasing the reliability of the connection.

[0049] Optionally, the connecting part is screwed or snapped into the lamp holder 102.

[0050] In some embodiments, please refer to Figures 1 to 4 The lamp holder 102 includes a base 1022, an end cap 1021, and a locking member 1023. The base 1022 has a receiving groove extending along its long axis at its bottom. The end cap 1021 is located at the end of the base 1022 and covers the opening of the receiving groove. The locking member 1023 is located in the receiving groove and connected to the base 1022. The locking member 1023 is used to connect with the lamp cover 101.

[0051] This embodiment uses a locking member 1023 as an intermediate connecting component to connect the base 1022 and the lampshade 101. Compared to the solution of directly snapping or screwing the lamp holder 102 and the lampshade 101 together, this method has stronger structural compatibility with the lamp holder 102 and the lampshade 101, eliminating the need for snap-fit ​​or screw-fit structures on the lamp holder 102 and the lampshade 101. It can be adapted to lamp holders 102 and lampshades 101 with different structures. In addition, since the locking member 1023 is located in the receiving groove, it is not exposed to the outside, thus avoiding affecting the light output effect.

[0052] Specifically, the lampshade 101 closes the bottom of the receiving groove, forming a receiving cavity 103.

[0053] Optionally, the locking element 1023 is bonded or screwed to the lamp holder 102, and snapped or hung to the lamp cover 101 to avoid openings in the lamp cover 101, ensuring the sealing and integrity of the lamp cover 101 and preventing light leakage.

[0054] In some embodiments, please refer to Figures 1 to 4 The lampshade 101 includes a cover body 1012 and a sealing cover 1011. The cover body 1012 includes a mounting part and a light-emitting part 1012-1 connected to the bottom of the mounting part. The mounting part and the light-emitting part 1012-1 enclose a first chamber 1031 for accommodating the light source 6. The lampshade 101 is connected to the mounting part and forms a second chamber 1032 with the mounting part. The first chamber 1031 and the second chamber 1032 together constitute a receiving cavity 103. The sealing cover 1011 is connected to the end of the cover body 1012 for sealing the first chamber 1031.

[0055] The mounting section divides the receiving cavity 103 into a first chamber 1031 and a second chamber 1032. The light source 6 is located in the first chamber 1031, while the driver 3, terminal block 2, and connecting wire 4 are located in the second chamber 1032. The mounting section provides mounting positions for these components. This embodiment not only achieves a rational partitioning, avoiding light leakage due to the clearance hole of the terminal block 2 on the lamp holder 102, ensuring that the light is projected entirely outward from the light emitting section 1012-1, but also prevents the heat from components such as the driver 3 from affecting the normal operation of the light source 6.

[0056] In some embodiments, please refer to Figures 1 to 4 The mounting section has a locking hole, and the sealing cover 1011 has a buckle 1013 adapted to the locking hole, which engages with the locking hole.

[0057] The sealing cover 1011 and the mounting part are detachably connected by the snap-fit ​​1013 and the snap-fit ​​hole, eliminating the need for external connecting parts, simplifying the installation steps and making it easier to disassemble and assemble.

[0058] In some embodiments, please refer to Figures 1 to 4 The mounting section includes a mounting plate and mounting lugs 1012-3. The mounting plate is connected to the light-emitting section 1012-1. The mounting lugs 1012-3 are located on the top of the mounting plate and are engaged with the lampshade 101.

[0059] The lampshade 101 engages with the mounting lugs 1012-3 on the top of the mounting plate, connecting the lampshade 101 to the lamp holder 102, making assembly and disassembly more convenient. Furthermore, this embodiment avoids the problem of uneven outer walls of the lampshade 101 caused by snap-fit ​​components on its outer edge, which would affect light refraction.

[0060] In some embodiments, please refer to Figures 1 to 4The locking member 1023 includes a connecting piece 1023-1 and locking pieces 1023-2 disposed on opposite sides of the connecting piece 1023-1. The connecting piece 1023-1 is connected to the lamp cover 101, and the locking piece 1023-2 is used to connect to the lamp cover 101.

[0061] Two locking pieces 1023-2 are connected to the lampshade 101 respectively, making the lampshade 101 more evenly stressed and increasing the stability and reliability of the connection, thus preventing the lamp from tilting after it is fixed.

[0062] Optionally, the locking piece 1023-2 can be snapped, screwed, or hooked onto the lampshade 101.

[0063] In some embodiments, please refer to Figures 1 to 4 The locking piece 1023-2 has a snap-fit ​​protrusion 1023-3 at its end, and the lamp cover 101 has a fixed protrusion located in the receiving cavity 103. The snap-fit ​​protrusion 1023-3 and the fixed protrusion snap-fit ​​together.

[0064] The snap-fit ​​protrusion 1023-3 engages with the fixing protrusion to achieve a detachable connection between the lamp holder 102 and the lamp cover 101, facilitating subsequent maintenance of the lamp. Furthermore, after connection, both the snap-fit ​​protrusion 1023-3 and the fixing protrusion are located within the receiving cavity 103, preventing external forces from affecting the connection between the lamp cover 101 and the lamp holder 102, thus increasing the reliability and stability of the connection.

[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
