Description

Technical Field

[0001] This utility model relates to the field of downlight technology, and in particular to a downlight housing structure. Background Technology

[0002] Downlights, as a type of recessed lighting fixture, are widely used in various scenarios such as home decoration, commercial offices, and public places due to their advantages of concealed installation, soft light, and high space utilization. During the installation and use of downlights, the arrangement and fixing of the power cord are crucial factors affecting the ease of installation, safety of use, and product stability.

[0003] Existing downlight housings typically only have holes for the power cord to pass through. The lack of a dedicated restraint mechanism after the cord exits negatively impacts the neatness of the installation, and exacerbates the messy wiring problem, especially in scenarios requiring multiple wires. Furthermore, the core components like the LED bulbs generate significant heat during operation. While existing downlight housings often incorporate heat dissipation fins to ensure effective cooling, these fins serve only a single function and fail to fully utilize the structural space to address the issue of messy power cord wiring. Additionally, some downlights attempt to secure the power cord using methods like wrapping with tape or cable ties, but these methods are cumbersome and fail to balance wiring neatness, ease of installation, and effective heat dissipation. Utility Model Content

[0004] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a housing structure for a downlight.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A downlight housing structure includes a housing body and a wire clamping component. The housing body includes a heat sink and a headlight cover detachably mounted on the front end of the heat sink. The rear end of the heat sink has a wire hole for the power cord to pass through. A plurality of heat sink fins are evenly distributed on the circumferential sidewall of the heat sink. A wire release gap is formed between two adjacent heat sink fins to allow the power cord to pass through. The wire clamping component is detachably engaged between two adjacent heat sink fins to confine the power cord within the wire release gap.

[0007] In some embodiments, a horizontal notch is provided on the sidewall of each of the heat dissipation fins, and the pressure member includes a transverse pressure plate and hooks respectively provided at both ends of the transverse pressure plate. The two hooks are engaged with the outside of two adjacent heat dissipation fins, and the two hooks are engaged with the corresponding horizontal notch.

[0008] In some embodiments, a limiting groove is provided at the end of each of the heat dissipation fins, and when the hook is engaged in the horizontal notch, the transverse pressure plate is engaged in the limiting groove.

[0009] In some embodiments, the headlight cover and the heat sink are detachably installed by a number of screws. The outer side of the headlight cover is provided with a number of screw posts along the circumference, and the front edge of the heat sink is provided with a convex ring. The convex ring is provided with a number of through holes corresponding to the screw posts. The screws pass through the through holes and engage with the screw posts in a threaded manner.

[0010] In some embodiments, a plurality of reinforcing ribs are provided along the circumference on the outer side of the headlight cover.

[0011] In some embodiments, each of the reinforcing ribs is provided with a limiting flange for limiting the convex ring, and the convex ring is disposed within a plurality of limiting flanges.

[0012] In some embodiments, a guide slope is provided on the inner side of the end of the limiting flange.

[0013] In some embodiments, a protruding strip is provided on the inner side of the limiting flange, and the protruding strip can be engaged with the protruding ring.

[0014] In some embodiments, there are two symmetrical spring clips on the outer side of the headlight cover.

[0015] In some embodiments, the front end of the headlight cover is integrally formed with a face ring.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By creating independent wire-laying gaps between adjacent heat dissipation fins on the heat sink, and with the help of detachable wire clamping components, both single power cords and multiple wires can be stably confined within the wire-laying gaps, either individually or collectively. This effectively prevents wire displacement, tangling, or compression, solves the problem of messy multi-wire wiring, and makes the wiring after the light fixture is installed neater and more orderly, improving the overall installation quality.

[0018] 2. The heat dissipation fins retain their original core function of uniform heat dissipation, and the gaps between them are cleverly transformed into dedicated wiring spaces. There is no need to add redundant structures such as wiring slots and fixing seats. It is especially suitable for wiring needs with multiple wires. Without increasing the size of the housing or affecting the heat dissipation efficiency, it achieves efficient integration of heat dissipation and wiring functions, making the downlight structure more compact and space utilization more efficient.

[0023] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0024] like Figures 1-4 The diagram shows the housing structure of a downlight, which includes a housing body 1 and a wire clamping component 5. The housing body 1 includes a heat dissipation shell 2 and a headlight cover 3 detachably mounted on the front end of the heat dissipation shell 2. The rear end of the heat dissipation shell 2 is provided with a wire hole for the power cord 10 to pass through. A plurality of heat dissipation fins 6 are evenly distributed on the circumferential side wall of the heat dissipation shell 2. A wire release gap 4 is formed between two adjacent heat dissipation fins 6 to allow the power cord 10 to pass through. The wire clamping component 5 is detachably clamped between two adjacent heat dissipation fins 6 to restrict the power cord 10 in the wire release gap 4.

[0025] During wiring, first thread the power cord 10 of the downlight through the pre-set wire hole at the rear end of the heat sink 2. Depending on the wiring path and quantity requirements of the installation scenario, select any of the evenly distributed wire gaps 4 on the circumferential sidewall of the heat sink 2 and place the threaded power cord 10 directly into the wire gap 4. If there are multiple wires, they can be placed together in the same wire gap 4 or in different wire gaps 4. After the power cord 10 is positioned within the wire gap 4, align the wire clamp 5 with the selected two adjacent heat sink fins 6. Install the wire clamp 5 between the two heat sink fins 6 using a detachable locking mechanism to confine the power cord 10 within the wire gap 4 and prevent it from shifting.

[0026] The combined structure of the wire gap 4 and the clamping device 5 can stably confine the power cord 10 within a fixed space, effectively preventing the displacement, tangling, or compression of single or multiple wires. This solves the problem of messy wiring in traditional downlights, making the wiring after installation neater and more orderly, and improving the standardization of construction and overall aesthetics.

[0027] See Figure 2 , Figure 4 As shown, a horizontal notch 21 is provided on the side wall of each of the heat dissipation fins 6. The pressure member 5 includes a horizontal pressure plate 22 and hooks 23 respectively provided at both ends of the horizontal pressure plate 22. The two hooks 23 are engaged with the outside of two adjacent heat dissipation fins 6, and the two hooks 23 are engaged with the corresponding horizontal notch 21.

[0028] Furthermore, a limiting groove 31 is provided at the end of each of the heat dissipation fins 6. When the hook 23 is hooked into the horizontal notch 21, the transverse pressure plate 22 is engaged in the limiting groove 31.

[0029] When installing the wire clamping component 5, hold the component and align its horizontal clamping plate 22 with the power cord 10 above the wire release gap 4. Simultaneously, align the hooks 23 at both ends of the horizontal clamping plate 22 with the outer walls of the two adjacent heat sink fins 6. Press the wire clamping component 5 along the length of the heat sink fins 6, causing the two hooks 23 to slide against the outer side of the heat sink fins 6 until the hooks 23 are embedded in the pre-set horizontal notches 21 on the side walls of the heat sink fins 6, thus positioning the wire clamping component 5 in the longitudinal direction of the heat sink fins 6. When the hooks 23 are fully engaged in the horizontal notches 21, the horizontal clamping plate 22 is precisely engaged in the limiting grooves 31 at the ends of the two adjacent heat sink fins 6, forming a double fixing structure with longitudinal limiting by the hooks and the horizontal notches, and lateral limiting by the horizontal clamping plate and the limiting grooves. The horizontal clamping plate 22 can confine the power cord 10 within the wire release gap 4, preventing the power cord 10 from shifting in the lateral and longitudinal directions.

[0030] See Figure 1 , Figure 3 , Figure 4 As shown, the headlight cover 3 and the heat sink 2 are detachably installed by a number of screws 44. The outer side of the headlight cover 3 is provided with a number of screw posts 41 along the circumference. The front edge of the heat sink 2 is provided with a convex ring 42. The convex ring 42 is provided with a number of through holes 43 corresponding to the screw posts 41. The screws 44 pass through the through holes 43 and are threaded into the screw posts 41.

[0031] During the downlight assembly stage, first align the front lamp cover 3 with the front end of the heat sink 2, so that the screw posts 41 distributed on the outer circumference of the front lamp cover 3 are aligned with the through holes 43 on the front edge protrusion ring 42 of the heat sink 2. After the screw posts 41 and the through holes 43 are fully aligned, pass the screws 44 one by one through the through holes 43 on the protrusion ring 42 and engage with the corresponding screw posts 41. By tightening the screws 44, the axial locking force of the threaded connection is used to tightly fit and fix the front lamp cover 3 and the heat sink 2 together.

[0032] Furthermore, a plurality of reinforcing ribs 50 are provided along the circumference on the outer side of the headlight cover 3, and a limiting flange 51 for limiting the convex ring 42 is provided on each of the reinforcing ribs 50. The convex ring 42 is disposed within the plurality of limiting flanges 51. A guide slope 61 is provided on the inner side of the end of the limiting flange 51, and a protruding strip 71 is provided on the inner side of the limiting flange 51. The protruding strip 71 can be engaged on the convex ring 42.

[0033] When assembling the headlight cover 3 and the heat sink 2, first align the headlight cover 3 with the front end of the heat sink 2. At this time, the guide slope 61 on the inner side of the end of the limiting flange 51 on the outer circumference of the headlight cover 3 contacts the edge of the convex ring 42 of the heat sink 2. The guide slope 61 plays a guiding role, guiding the convex ring 42 to slide smoothly into the annular space surrounded by several limiting flanges 51, quickly completing the initial pre-positioning and reducing the difficulty of alignment. As the headlight cover 3 and the heat sink 2 gradually fit together, the convex ring 42 completely enters the inner side of the limiting flange 51. The limiting flange 51 forms a circumferential limit on the convex ring 42 from the radial direction, preventing the convex ring 42 from shifting in the circumferential direction. At the same time, the protrusion 71 on the inner side of the limiting flange 51 fits and engages with the surface of the convex ring 42, forming an axial limit, further restricting the relative displacement of the headlight cover 3 and the heat sink 2.

[0034] The reinforcing ribs 50 on the outer side of the headlight cover 3 are distributed along the circumference and are integrally formed with the headlight cover 3 body and the limiting flange 51, which greatly improves the overall structural rigidity of the headlight cover 3 and prevents it from deforming during assembly, transportation or use. At the same time, the reinforcing ribs 50 provide stable support for the limiting flange 51, ensuring that the limiting force of the limiting flange 51 on the convex ring 42 is stable and reliable, and forming a stronger structural integrity in conjunction with the threaded connection.

[0035] In this utility model, there are two symmetrical spring clips 81 on the outer side of the front lamp cover 3. The downlight is installed on the ceiling or ceiling through the spring clips 81. The spring clips 81 are existing conventional designs and will not be described in detail here.

[0036] In this utility model, the front end of the headlight cover 3 is integrally formed with a face ring 91.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
