Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0024] This utility model provides a lamp that facilitates the replacement of LED lights, and its structure is as follows: Figure 1 - Figure 3 As shown, it includes a cover mechanism 1 and a lighting mechanism 2.

[0025] The cover mechanism 1 includes a lampshade 11, a first lamp holder 12, a second lamp holder 13, and a fixing component 14. The lampshade 11 is detachably connected to the first lamp holder 12. The first lamp holder 12 is slidably connected to the second lamp holder 13 along the height direction of the second lamp holder 13. The fixed end of the fixing component 14 is connected to the second lamp holder 13, and the movable end of the fixing component 14 is connected to the first lamp holder 12.

[0026] The lighting mechanism 2 includes a bulb 21, a plug 22, and a socket 23. The bulb 21 is electrically connected to the plug 22, the plug 22 is plugged into the socket 23, and the socket 23 is connected to the second lamp holder 13.

[0027] In use, the bulb 21 of the lighting mechanism 2 is pre-plugged into the socket 23 in the second lamp holder 13 through the plug 22 to form a stable electrical connection; the first lamp holder 12 slides to the working position along the height direction of the second lamp holder 13. At this time, the fixed end and the movable end of the fixing component 14 cooperate to lock each other, so that the first lamp holder 12 and the second lamp holder 13 remain relatively fixed. The lampshade 11 is fixed on the first lamp holder 12 through a detachable connection, forming a closed lighting structure as a whole, and the bulb 21 emits light normally. When bulb 21 needs to be replaced, operate the movable end of the fixing component 14 to release its locking relationship with the fixed end, so that the first lamp holder 12 has the freedom to slide along the height direction of the second lamp holder 13. Push the first lamp holder 12 downward along the height direction of the second lamp holder 13. The first lamp holder 12 drives the lamp cover 11 to move synchronously until the socket 23 and the plug 22 and bulb 21 in the second lamp holder 13 are completely exposed in the operating space. Directly disassemble the connection between the old bulb 21 and the plug 22. After reassembling the new bulb 21 and the original plug 22, slide the first lamp holder 12 in the opposite direction to the initial working position. Operate the fixing component 14 to lock the first lamp holder 12 and the second lamp holder 13. Finally, fix the lamp cover 11 back to the first lamp holder 12 to complete the replacement.

[0028] In this invention, the first lamp holder 12 is slidably adjusted to expose the bulb 21, thereby facilitating the replacement of the bulb 21. The plug 22 and the socket 23 are always in a plugged-in state, avoiding mechanical damage caused by repeated plugging and unplugging, and improving the service life of the plug 22 and the socket 23.

[0029] To fix the first lamp holder 12 in the predetermined position, please refer to... Figure 2In a preferred embodiment, the fixing component 14 includes a slider 141, a spring rod 142, and a locking head 143. The slider 141 is connected to the first lamp holder 12. The second lamp holder 13 is provided with a sliding groove 144 for the slider 141 to slide. The two spring rods 142 are respectively connected to the top and bottom of the slider 141. The locking head 143 is connected to the end of the spring rod 142. The second lamp holder 13 is provided with a guide groove 145 and a locking slot 146 at the top and bottom of the sliding groove 144. The guide groove 145 and the locking slot 146 are connected. The guide groove 145 is adapted to the spring rod 142, and the locking slot 146 is adapted to the locking head 143.

[0030] When in use, when the first lamp holder 12 slides along the slide groove 144 to the working position, the spring rods 142 at the top and bottom of the slider 141 are aligned with the guide groove 145 of the second lamp holder 13. The spring rods 142 naturally extend into the guide groove 145 under their own elastic force. As the slider 141 continues to move to the limit position, the locking head 143 at the end of the spring rod 142 slides along the guide groove 145 to the end. At this time, because the diameter of the locking head 143 is slightly larger than the width of the guide groove 145, it will squeeze the side wall of the guide groove 145, causing the spring rod 142 to produce a slight elastic deformation. When the locking head 143 is fully inserted into the slot 146, the elastic potential energy of the spring rod 142 is released and it returns to its original shape, driving the locking head 143 to be locked into the slot 146. At this time, the side wall of the slot 146 blocks the movement of the card head 143 along the guide groove 145. The guide groove 145 restricts the lateral displacement of the spring rod 142, forming a two-way constraint, so that the slider 141 is relatively fixed with the slide groove 144, thereby locking the first lamp holder 12 in the working position.

[0031] To simplify locking and unlocking, please refer to... Figure 2 In a preferred embodiment, the card head 143 is triangular in shape.

[0032] In use, the two waist-shaped surfaces of the triangular locking head 143 form a natural guide surface. When the slider 141 moves the spring rod 142 towards the slot 146, even if there is a slight misalignment between the spring rod 142 and the guide groove 145, the inclined surface of the locking head 143 can still contact the edge of the guide groove 145 and automatically correct its direction, guiding the spring rod 142 to slide precisely into the guide groove 145 without manual alignment. When pressing the locking head 143 to unlock, the inclined surface of the triangular locking head 143 forms a sliding contact with the edge of the slot 146. Compared with the point contact of the hemispherical locking head 143, the contact area is larger and the force direction is gentler, which can reduce the pressing force required to unlock and avoid damage to the spring rod 142 due to excessive force.

[0033] To reduce wear on the 143 chuck, please refer to... Figure 2 In a preferred embodiment, the fixing component 14 further includes a wear-resistant layer attached to the surface of the clip head 143.

[0034] During use, the wear-resistant layer is made of polytetrafluoroethylene (PTFE), with a surface hardness of HV300-500 and a coefficient of friction as low as 0.05-0.1. In frequent operation scenarios, this reduces the wear rate of the chuck 143.

[0035] To improve the sealing of the light fixtures, please refer to... Figure 2 In a preferred embodiment, the cover mechanism 1 further includes a sealing component 3, which includes a convex sealing layer 31 and a concave sealing layer 32. The convex sealing layer 31 is connected to the top of the slider 141, and the concave sealing layer 32 is connected to the top of the groove 144 on the second lamp holder 13. The convex sealing layer 31 and the concave sealing layer 32 are adapted to each other.

[0036] In use, the convex sealing layer 31 and the concave sealing layer 32 are made of silicone. The convex sealing layer 31 is connected to the top of the slider 141, and the concave sealing layer 32 is fixed to the inner wall of the second lamp holder 13 at the top of the slide groove 144. When the slider 141 slides along the slide groove 144, the convex sealing layer 31 is always embedded in the groove of the concave sealing layer 32, forming a tight fit structure of convex and concave, filling the gap between the slider 141 and the slide groove 144, and blocking the intrusion path of dust and moisture.

[0037] To improve the heat dissipation of the lamps, please refer to... Figure 1 In a preferred embodiment, the cover mechanism 1 further includes a heat dissipation component 4, which includes a heat-conducting ring 41 connected to the second lamp holder 13. The heat-conducting ring 41 is arranged around the periphery of the plug 22 and the socket 23, and the outer side of the heat-conducting ring 41 is in contact with the outside air.

[0038] When in use, after the plug 22 and socket 23 are plugged in and powered on, Joule heating is generated when current flows due to the contact resistance of the metal contacts. The heat is concentrated at the contact points between the metal prongs of the plug 22 and the metal contacts of the socket 23, as well as around the connection gap between the plug 22 and the socket 23. The heat-conducting ring 41 achieves precise heat collection through its ring-shaped enveloping structure. The heat-conducting ring 41 is fixedly connected to the inner wall of the second lamp holder 13, and the ring structure completely surrounds the periphery of the plug 22 and socket 23, so that the inner wall of the heat-conducting ring 41 is in close contact with the outer walls of the plug 22 and socket 23. Through air convection and radiation heat exchange, the heat generated by the plug 22 and socket 23 is quickly transferred to the surface of the heat-conducting ring 41.

[0039] To further improve the heat dissipation of the lamps, please refer to... Figure 1 In a preferred embodiment, the heat dissipation assembly 4 further includes heat dissipation fins 42, and a plurality of heat dissipation fins 42 are arranged around the outside of the heat conduction ring 41.

[0040] In use, the heat dissipation fins 42 are connected to the outer wall of the heat conduction ring 41 by an integral molding method. When the plug 22 and socket 23 are powered on and generate heat, the heat is first transferred to the inner wall of the heat conduction ring 41 through air conduction and thermal radiation. The heat conduction ring 41 quickly transfers the heat to the outer wall due to its high thermal conductivity. The heat is evenly distributed to each heat dissipation fin 42 through the connection surface between the fins and the heat conduction ring 41. A single heat dissipation fin 42 can provide a larger heat dissipation area than the outer surface of the heat conduction ring 41. The larger surface area means an increased contact with the outside air, and the number of air molecules that can exchange heat at the same time is significantly increased, providing a physical basis for the rapid dissipation of heat.

[0041] For easy fixing of the lampshade 11, please refer to... Figure 3 In a preferred embodiment, the cover mechanism 1 further includes a positioning component 5 and a locking component 6. The positioning component 5 includes a positioning ring 51 and a positioning groove 52. The positioning ring 51 is connected to the lamp cover 11, and the positioning groove 52 is connected to the first lamp holder 12. The positioning ring 51 and the positioning groove 52 are adapted to each other.

[0042] In use, when the opening of the lampshade 11 is aligned with the edge of the first lamp holder 12, the arc-shaped surface of the positioning ring 51 first contacts the entrance edge of the positioning groove 52. Upon contact, it will naturally slide along the edge of the positioning groove 52, generating a guiding effect. Even if there is a slight misalignment between the lampshade 11 and the first lamp holder 12, the position can be automatically corrected by the sliding of the positioning ring 51. As the lampshade 11 is pressed against the first lamp holder 12, the positioning ring 51 is fully embedded in the positioning groove 52. At this time, the outer wall of the positioning ring 51 is tightly fitted with the inner wall of the positioning groove 52, forming a circumferential constraint, restricting the rotation of the lampshade 11 in the horizontal direction and the radial offset, ensuring that the central axis of the lampshade 11 coincides with that of the first lamp holder 12, and providing an installation base for fixing the lampshade 11.

[0043] To make it easier for the positioning ring 51 to enter the positioning groove 52, please refer to... Figure 3 In a preferred embodiment, the positioning ring 51 has a rounded chamfer on the side near the positioning groove 52.

[0044] When the positioning ring 51 and the positioning groove 52 are initially aligned, the right-angled edge is prone to jamming due to the sharp edge, which can cause installation to be stuck. However, the curved surface structure with rounded chamfers can guide the positioning ring 51 to slide smoothly into the positioning groove 52 along the entrance edge.

[0045] To secure the lampshade 11 to the first lamp holder 12, please refer to... Figure 3 In a preferred embodiment, the locking component 6 includes a first magnetic sheet 61 and a second magnetic sheet 62. The first magnetic sheet 61 is connected to the positioning ring 51, and the second magnetic sheet 62 is connected to the positioning groove 52. The first magnetic sheet 61 and the second magnetic sheet 62 are attracted to each other.

[0046] During use, when installing the lampshade 11, the chamfered edge of the positioning ring 51 first contacts the positioning groove 52, guiding the lampshade 11 to precisely align with the first lamp holder 12. At this time, the first magnetic piece 61 and the second magnetic piece 62 are coaxial but not in contact, and the magnetic force begins to generate a weak pre-adsorption force to assist the user in further aligning the position. When the positioning ring 51 is fully embedded in the positioning groove 52, the distance between the two magnetic pieces decreases, and the adsorption force increases instantaneously, firmly adsorbing the lampshade 11 onto the first lamp holder 12. At this time, the positioning component 5 restricts radial offset and rotation, and the magnetic locking component 6 provides axial clamping force, forming a three-dimensional constraint so that the lampshade 11 will not loosen under conditions such as vibration and slight impact.

[0047] To better understand this utility model, the following is combined with... Figure 1 - Figure 3 The working principle of a lamp that facilitates LED lamp replacement is described in detail below: The bulb 21 of the lighting mechanism 2 is pre-connected to the socket 23 in the second lamp holder 13 via the plug 22, forming a stable electrical connection; the first lamp holder 12 slides to the working position along the height direction of the second lamp holder 13, at which time the fixed end and the movable end of the fixing component 14 cooperate and lock each other, so that the first lamp holder 12 and the second lamp holder 13 remain relatively fixed, and the lamp cover 11 is fixed on the first lamp holder 12 by a detachable connection, forming a closed lighting structure, and the bulb 21 emits light normally. When bulb 21 needs to be replaced, operate the movable end of the fixing component 14 to release its locking relationship with the fixed end, so that the first lamp holder 12 has the freedom to slide along the height direction of the second lamp holder 13. Push the first lamp holder 12 downward along the height direction of the second lamp holder 13. The first lamp holder 12 drives the lamp cover 11 to move synchronously until the socket 23 and the plug 22 and bulb 21 in the second lamp holder 13 are completely exposed in the operating space. Directly disassemble the connection between the old bulb 21 and the plug 22. After reassembling the new bulb 21 and the original plug 22, slide the first lamp holder 12 in the opposite direction to the initial working position. Operate the fixing component 14 to lock the first lamp holder 12 and the second lamp holder 13. Finally, fix the lamp cover 11 back to the first lamp holder 12 to complete the replacement.

[0048] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
