Description

Technical Field

[0001] This utility model relates to the field of lighting fixture technology, and in particular to a waterproof lamp head structure for cord lamps that is easy to automate with coating. Background Technology

[0002] With the continuous development of LED lighting technology, drop light lamps, due to their flexibility, thinness, and ease of wiring, are widely used in architectural outline lighting strips, landscape lighting, advertising decoration, and other scenarios. To improve the reliability of drop light lamps in complex outdoor environments, waterproof lamp holder structure has become one of the key technological development areas.

[0003] Existing waterproof lamp holders for cordless lights mostly use coated materials to enhance overall waterproof performance, but there are still several shortcomings in their structural design:

[0004] 1. Insufficient sealing reliability: The sealing treatment at the connection between the LED beads, cables and the lamp holder housing is not perfect. After long-term use, water leakage may occur, affecting the working stability and service life of the LED components.

[0005] 2. Inappropriate insert design affects illumination effect: Although some existing technologies have used rubber-coated materials to construct the lamp head body, the support inserts used to fix the lamp beads do not extend downwards to near the bottom of the lamp head. This results in the lamp beads being installed too high and the illumination angle being limited, thus causing uneven light scattering or blind spots, which cannot meet the actual lighting needs.

[0006] 3. Loose lamp holder structure and inconvenient maintenance: In some designs, the lamp holder and lamp body are not tightly fitted, making disassembly and assembly complicated and prone to loosening, which affects the overall sealing effect and structural stability.

[0007] Therefore, there is an urgent need for a waterproof lamp head structure for corded lamps that is structurally sound, has strong sealing properties, and can effectively improve the illumination performance of the lamp beads, in order to solve the above-mentioned problems in the existing technology and improve the performance and reliability of the product.

It can improve the waterproof sealing effect and improve the illumination performance of the lamp beads 22. It includes a support insert 1, a cord lamp string 2, a lamp head cover 3, and a lamp head body 4 made of coating material.

[0032] The lamp holder body 4 has a hollow shell structure and is preferably made of flexible waterproof materials such as transparent or semi-transparent silicone or TPU. It has an insert installation port 5 at the top for installing inserts.

[0033] The support insert 1 is made of a sturdy material (such as ABS or nylon) and its shape matches the insert mounting opening 5. It can be inserted from the upper end of the lamp head body 4 and firmly embedded inside the lamp head body 4. The outer side of the support insert 1 fits tightly against the inner wall of the mounting opening of the lamp head body 4 to form a sealed fit. The support insert 1 extends downward to near the lower end of the lamp head body 4, and its lower end is provided with a lamp bead 22 mounting seat for fixing the lamp beads 22 in the cord light string 2, so that its light source is close to the bottom edge of the lamp head, thereby optimizing the light output effect.

[0034] The light string 2 is introduced from one end of the lamp holder body 4, and the cables 21 on both sides pass through the outlet ports on both sides of the lamp holder body 4, running through the entire lamp holder body 4 and extending to an external power source or connection device. The cables 21 and the outlet ports are also sealed together through structural fit or auxiliary sealing treatment (such as glue sealing, heat shrinking, etc.) to further enhance the overall protection effect.

[0035] The lamp head cover 3 is located at the lower end of the lamp head body 4 and can be detachably connected by a snap or a screw fastener. Its top, the bottom of the support insert 1, and the bottom of the lamp head body 4 are flush and aligned after installation to achieve closed protection while maintaining a flat appearance.

[0036] Working principle of Example 1:

[0037] During assembly, the support insert 1 is first installed inside the lamp head body 4, the light string 2 is inserted and fixed to the insert, and then the lamp head cover 3 is installed and coated with glue. The glue material covers the entire exterior of the lamp head body 4, making the entire lamp head form an integrated sealed structure, improving its waterproof rating and mechanical strength.

[0038] The structure provided in this embodiment can effectively improve the illumination performance of the lamp bead 22, while enhancing the waterproof sealing effect of the lamp head.

The design of the lamp holder hook 6 enhances the operability of the lamp and is particularly suitable for outdoor temporary lighting or scenarios requiring rapid deployment.

[0041] Preferably, the inner wall of the lamp holder body 4 is provided with an internal threaded groove, as shown in the reference. Figure 3 The lamp head cover 3 has a connecting part 7 extending upward from the top. The outer side wall of the connecting part 7 is provided with external threads, and the lamp head body 4 is threaded onto the connecting part 7.

[0042] Specifically, in this embodiment, to further enhance the structural stability and waterproof sealing between the lamp holder cover 3 and the lamp holder body 4, the inner sidewall of the lamp holder body 4 is provided with an internal threaded groove; the top of the lamp holder cover 3 extends upward to form a connecting part 7, and its outer sidewall is provided with an external thread that mates with the internal thread of the lamp holder body 4. During assembly, the lamp holder cover 3 is screwed into the lamp holder body 4 via the thread, ensuring a firm connection and precise positioning, effectively preventing loosening caused by vibration, impact, or pulling, while further improving the structural sealing. This threaded connection not only improves the weather resistance and protection level of the lamp holder assembly but also provides convenience for later maintenance and replacement operations.

[0043] Preferred, Reference Figure 4 The support insert 1 has placement slots 8 on its left and right sides, and a placement opening 9 at its lower end. The cables 21 on both sides of the wire light string 2 are embedded in the placement slots 8, and the lamp beads 22 of the wire light string 2 are fixed at the bottom of the opening of the lamp bead 22.

[0044] Specifically, in this embodiment, by setting a placement slot 8 and an opening for the lamp bead 22 on the support insert 1, not only is the installation accuracy and structural stability of the component improved, but also the consistency of light effect and the reliability of the finished lamp head are enhanced, making it suitable for outdoor lighting products that require high brightness and strong protection.

[0045] Example 2, refer to Figure 5 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides heat dissipation holes 10, heat dissipation fins 12, and dust filter 11, which can significantly enhance the heat dissipation performance and dust prevention capability of the waterproof lamp head structure of the cord lamp. Among them, multiple evenly distributed heat dissipation holes 10 are provided on the front and rear sides of the support insert 1, and the shape of the heat dissipation holes 10 is regular hexagonal; a dust filter 11 is provided inside the heat dissipation holes 10; the support insert 1 is made of thermally conductive material, and multiple heat dissipation fins 12 are also provided on the front and rear sides of the support insert 1, and the heat dissipation fins 12 are distributed in the gaps between adjacent heat dissipation holes 10.

[0046] Working principle of Example 2:

[0047] The support insert 1 is made of a material with good thermal conductivity, such as aluminum alloy or thermally conductive plastic. Its shape matches the inner cavity of the lamp holder body 4, and it is embedded in it from top to bottom, sealing it tightly to effectively improve heat conduction and ventilation performance. Multiple evenly distributed heat dissipation holes 10 are provided on the front and rear sides of the support insert 1. The holes are preferably hexagonal, which facilitates the distribution of heat dissipation airflow while maintaining structural strength. Each heat dissipation hole 10 has a dust filter 11 inside, which prevents dust, insects, and other foreign objects from entering, ensuring long-term cleanliness and stable operation of the internal structure. Multiple heat dissipation fins 12 are arranged horizontally between adjacent heat dissipation holes 10, increasing the heat dissipation surface area, accelerating air convection, and further improving heat dissipation efficiency.

[0048] Based on the existing lamp head structure, this embodiment greatly improves the thermal management performance and operational stability of the product by introducing hexagonal heat dissipation holes 10, thermally conductive materials, heat dissipation fins 12 and dust filter 11. It is particularly suitable for high-brightness, long-term lighting application scenarios, while also taking into account the comprehensive performance advantages of waterproof, dustproof and easy maintenance.

[0049] Example 3 is the third embodiment of this utility model. Unlike the previous embodiment, this embodiment provides a reflective film, which can enhance the light emission efficiency of the lamp bead 22. The inner wall surface of the placement opening 9 is coated with a reflective film.

[0050] Working principle of Example 3:
