Description

Technical Field

[0001] This utility model relates to the field of downlight technology, specifically a split-type downlight structure. Background Technology

[0002] Downlights are light fixtures with a screw-in lamp holder that can directly mount incandescent or energy-saving bulbs. Most are recessed into the ceiling, projecting light downwards. These concealed fixtures, installed inside the ceiling, project all light downwards, providing direct light distribution and are widely used.

[0003] In existing technologies, most common downlights are integrated structures with tightly coupled components, making easy disassembly difficult. Maintenance or replacement often requires specialized tools such as screwdrivers and wrenches to disassemble numerous screws and clips, a tedious and complex process. Some traditional downlights fasten the fixture to the housing with a large number of screws, and the internal wiring is complex, requiring maintenance personnel to spend considerable time identifying the wiring and removing numerous obstructing components before reaching the faulty fixture for replacement. This integrated design not only consumes a significant amount of maintenance personnel's time and extends maintenance time but also demands a high level of expertise, making it impossible for ordinary users to operate independently. When a problem occurs, the high difficulty and cost of maintenance often lead users to replace the entire downlight, resulting in wasted resources and economic losses.

[0004] In view of this, we have introduced a split-type downlight structure. Utility Model Content

[0005] The purpose of this utility model is to provide a split-type downlight structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a split-type downlight structure, comprising: a lower cover and an upper cover;

[0007] The upper cover is snapped onto the surface of the lower cover. The lower cover has symmetrically arranged positioning parts inside. One side of the positioning part has an integrally formed arc-shaped bend. The surface of the positioning part has a placement part A on one side of the arc-shaped bend, and a placement part B is provided on the other side of the positioning part. A through hole for wire harness to pass through is provided on the other side of the surface of the positioning part. The placement part A and the placement part B enable the placement and installation of terminal A.

[0008] The lamp is snapped onto the top of the upper cover. A disassembly mechanism is provided between the lamp and the upper and lower covers. The protrusion of the disassembly mechanism is inserted into the inside of the bottom protrusion ring of the lamp to fix and remove the lamp from the upper and lower covers. This design allows the lamp to be installed and removed without the need for tools, which greatly improves the efficiency of replacing bulbs or repairing lamps.

[0009] Preferably, the disassembly mechanism includes a terminal B connected to the bottom of the lamp on the side of the convex ring. The convex ring is connected to the bottom of the lamp, and the convex block is integrally provided on the inner side of the upper cover. The surface of the convex ring has an L-shaped groove for engaging the convex block. The surface of the upper cover has a concave groove for the terminal B to slide and engage. The terminal B passes through the concave groove and contacts the terminal A to control the lamp to emit light. The inner side of the upper cover has an arc plate. The "introduction-rotation locking" structure of the L-shaped groove can realize the rapid positioning of the lamp. The arc plate can fit against the outer wall of the convex ring to enhance stability. The concave groove provides a precise sliding path for the terminal B to ensure reliable circuit connection.

[0010] Preferably, a fixing post A is provided on the inner side of the lower cover, and a screw hole A is provided inside the fixing post A for screws to pass through. A fixing post B is provided on the inner side of the upper cover, and a screw hole B is provided inside the fixing post B for screws to pass through. The fixing post B is aligned with the fixing post A. After the screw passes through the aligned screw hole, the upper and lower covers can be rigidly fixed. With the snap-fit ​​structure, a double fastening is formed, which effectively prevents the shell from loosening due to vibration during long-term use.

[0011] Preferably, the inner sides of the lower cover and the upper cover are provided with annular grooves for engaging the protruding ring; the size of the annular grooves is precisely matched with the protruding ring, which can limit the protruding ring in the circumferential direction, avoid radial displacement after the lamp is installed, and ensure the terminal docking accuracy.

[0012] Preferably, the lamp has heat dissipation holes evenly spaced on the back surface of the lamp; the heat dissipation holes can quickly dissipate the heat generated when the lamp is working, reduce the temperature of the internal components, extend the service life of the lamp, and the evenly spaced distribution can ensure uniform heat dissipation and avoid local overheating.

[0013] Preferably, the inner side of the lower cover is provided with equally spaced slots A, and the inner side of slot A is provided with an arc-shaped locking block. The inner side of the upper cover is provided with a slot B for engaging the arc-shaped locking block. The arc-shaped locking block has a certain elasticity. After being embedded in slot B, it can achieve the initial pre-fixation of the upper and lower covers, providing a positioning reference for subsequent screw tightening and improving assembly efficiency.

[0014] Preferably, the surface of the lower cover is provided with a blocking block on one side of the positioning part for limiting terminal A; the blocking block can abut against terminal A from the side, and cooperate with the placement part A and B to form a three-dimensional limit, preventing terminal A from shifting during transportation or assembly, and ensuring the reliability of the circuit connection.

[0015] Preferably, the lamp is provided with an outer shell, and the lower cover and the upper cover are installed inside the outer shell, and the outer surface of the outer shell is provided with a lamp spring clip; the outer shell can protect the internal structure from dust and moisture, and the lamp spring clip can use elastic deformation to quickly snap the downlight into the ceiling mounting hole, which is compatible with ceiling panels of different thicknesses, making the installation convenient and stable.

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

[0017] (1) By adopting a split structure of “lower cover-upper cover-lamp”, the lower cover and the upper cover are double fixed by “snap-fit ​​+ screw fastening”, and the lamp is connected to the cover by a rotating snap-fit ​​structure of “L-shaped slot + protrusion”. The lamp can be quickly disassembled and installed without professional tools, which greatly reduces the maintenance difficulty and time cost.

[0018] (2) By limiting the terminal A through the blocking block, and in conjunction with the wire harness guiding function of the through hole, poor circuit contact caused by wire harness pulling can be prevented, thus improving electrical safety.

[0019] (3) The lamp can be mechanically fixed and disassembled by rotating, and the circuit between terminal B and terminal A is automatically switched on and off during the disassembly and assembly process. No additional wiring operation is required, making the operation safe and convenient and reducing maintenance costs. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a split-type downlight structure, including: a lower cover 1 and an upper cover 12. The lower cover 1 and the upper cover 12 serve as the basic load-bearing components of the downlight. The two are tightly spliced ​​through a double positioning and fixing structure. The inner side of the lower cover 1 has multiple slots A4 at equal intervals along the circumference. The inner wall of each slot A4 is integrally formed with an arc-shaped locking block 5. The arc-shaped locking block 5 is made of elastic plastic material and has a slight deformation capability. Correspondingly, the inner side of the upper cover 12 has slots B14 at positions corresponding to the slots A4. The slot opening size of the slot B14 is adapted to the arc-shaped locking block 5. During assembly, the arc-shaped locking block 5 is inserted into the slot B14 by pressing the upper cover 12, thereby achieving the initial locking and positioning of the two.

[0030] To further enhance connection stability, at least two fixing posts A2 are symmetrically arranged on the inner side of the lower cover 1. The fixing posts A2 extend along the axial direction of the lower cover 1, and through screw holes A3 are opened in the axial direction inside them. The inner side of the upper cover 12 is provided with a fixing post B15 at the position precisely aligned with the fixing posts A2. The fixing post B15 is also provided with screw holes B. After the upper and lower covers are initially positioned by the arc-shaped locking block and the slot, screws can be passed through screw holes B and screw holes A3 in sequence to achieve rigid fixation of the two, effectively avoiding loosening problems during long-term use.

[0031] The lower cover 1 has two sets of positioning parts 7 symmetrically arranged inside. The positioning parts 7 are connected to the lower cover 1 by an integrated injection molding process, which has excellent structural strength. One side of the positioning part 7 extends integrally to form an arc-shaped bend 6. The curvature of the arc-shaped bend 6 is adapted to the curvature of the inner wall of the lower cover 1, which can enhance the deformation resistance of the positioning part 7. The surface of the positioning part 7 is divided into sections according to the installation requirements of the terminal A. A placement part A9 is opened on the side near the arc-shaped bend 6, and a placement part B8 is opened on the other side. The shape and size of the placement part A9 and the placement part B8 are precisely matched with the structure of both ends of the terminal A, which can realize the fitting placement of the terminal A and prevent it from shifting during assembly or use.

[0032] Meanwhile, a blocking block 10 is provided on one side of the positioning part 7 on the surface of the lower cover 1. The blocking block 10 protrudes perpendicular to the surface of the lower cover 1 and its height is slightly higher than the thickness of the terminal A. It can limit the terminal A from the side and further improve the installation stability. In addition, a through hole 11 is provided on the side of the positioning part 7 away from the arc-shaped bend 6. The diameter of the through hole 11 is adapted to the diameter of the downlight wiring harness, allowing the wiring harness to pass through and make an electrical connection with the terminal A, laying the foundation for the subsequent power supply of the lamp.

[0033] The lamp 17 is quickly assembled and disassembled from the upper cover 12 and lower cover 1 via a dedicated disassembly mechanism. This mechanism balances connection stability and ease of operation. Specifically, a raised ring 21 is integrally connected to the center of the bottom of the lamp 17. Multiple L-shaped slots 22 are evenly distributed circumferentially on the outer surface of the raised ring 21. Each L-shaped slot 22 consists of an axial guide section and a circumferential locking section. Correspondingly, a protrusion 16 is integrally provided on the inner side of the upper cover 12 at a position corresponding to each L-shaped slot 22. The shape of the protrusion 16 is adapted to the locking section of the L-shaped slot 22. During assembly, the raised ring 21 is aligned with the annular groove 23 shared by the inner sides of the upper cover 12 and lower cover 1 and inserted. The protrusion 16 slides along the guide section of the L-shaped slot 22 to the bottom. Then, the lamp 17 is rotated, and the protrusion 16 engages with the locking section for fixation. During disassembly, the lamp 17 is rotated in the opposite direction to release the lock. No tools are required for this operation.

[0034] The inner side of the upper cover 12 is also provided with an arc-shaped plate 18, which is distributed circumferentially along the inner side of the annular groove 23. Its curvature is adapted to the outer surface of the convex ring 21, which can form lateral support after the convex ring 21 is installed, reducing the shaking of the lamp 17. At the same time, the bottom of the lamp 17 is connected to the side of the convex ring 21 with a terminal B19. The surface of the upper cover 12 is correspondingly provided with a concave groove 13. The length of the concave groove 13 is adapted to the sliding stroke of the terminal B19, and the width is slightly larger than the thickness of the terminal B19. When the lamp 17 is rotated and locked, the terminal B19 can slide into the concave groove 13 and penetrate the groove, and finally make close contact with the terminal A on the lower cover 1, forming a complete circuit path to realize the light emission control of the lamp 17.

[0035] To ensure the long-term stable operation of the lamp 17, multiple heat dissipation holes 20 are provided at equal intervals along the circumference on the back surface of the lamp 17. The heat dissipation holes 20 adopt an inclined design, which can not only quickly dissipate the heat generated when the lamp is working, but also effectively prevent dust and moisture from directly invading the internal components.

[0036] The outer casing 25 of the lamp 17 is made of high-strength aluminum alloy, which has good corrosion resistance and structural support. After the lower cover 1 and the upper cover 12 are assembled, they are fitted into the inner casing 25 to form a complete protection for the internal structure. Two lamp spring clips 24 are symmetrically provided on the outer surface of the casing 25. The lamp spring clips 24 are made of elastic metal and have arc-shaped bends at both ends. During installation, the downlight can be quickly snapped into the mounting hole in the ceiling by the elastic deformation of the spring clips, without the need for additional fasteners, which greatly improves the installation efficiency.

[0037] Specifically, during use, the inner side of the lower cover 1 has equally spaced slots A4 with arc-shaped locking blocks 5. During assembly, the upper cover 12 is aligned with the surface of the lower cover 1, so that the slots B14 on the inner side of the upper cover are precisely aligned with the arc-shaped locking blocks 5. The elastic deformation of the arc-shaped locking blocks 5 achieves the initial locking and positioning of the two. At the same time, the fixing posts A2 on the inner side of the lower cover 1 and B15 on the inner side of the upper cover are automatically aligned. The screws pass through the screw holes A3 of the fixing posts A and B of the fixing posts B to complete the rigid fastening of the two, forming an internal installation chamber.

[0038] The symmetrically arranged positioning parts 7 inside the lower cover provide an installation reference for terminal A: the arc-shaped bend 6 on one side of the positioning part can fit the arc-shaped contour of terminal A to assist in positioning; the placement parts A9 and B8 on the surface respectively support different parts of terminal A to achieve precise positioning; the blocking block 10 on one side of the positioning part further restricts the lateral displacement of terminal A to avoid installation misalignment; the external wire harness passes through the through hole 11 on the surface of the positioning part to achieve electrical connection with terminal A.

[0039] The protruding ring 21 at the bottom of the lamp 17 is inserted into the annular groove 23 on the inner side of the lower cover 1 and the upper cover 12. The L-shaped groove 22 on the surface of the protruding ring 21 is initially aligned with the protrusion 16 integrally formed on the inner side of the upper cover 12. The lamp 17 is rotated so that the protrusion 16 slides along the transverse groove of the L-shaped groove 22 to the bottom of the longitudinal groove, thereby achieving mechanical fixation of the lamp 17. At the same time, the terminal B19 at the bottom of the lamp slides into the concave groove 13 on the surface of the upper cover, passes through the concave groove, and makes close contact with the terminal A to establish a circuit connection. The arc plate 18 on the inner side of the upper cover 12 fits against the outer side of the protruding ring 21, further enhancing the stability of the lamp 17 installation.

[0040] The assembled lower cover 1, upper cover 12 and lamp 17 components are embedded into the housing 25. The lamp spring clip 24 on the outer surface of the housing can be elastically deformed, which makes it easy to quickly snap the entire downlight into the reserved hole in the ceiling or other mounting base to complete the overall installation.

[0041] When the external power supply is transmitted to terminal A through the wire harness and through hole 11, the contact part between terminal A and terminal B19 forms a conductive path. The current is input into the light source component inside the lamp 17 through terminal B19, driving the lamp 17 to emit light. The heat dissipation holes 20 opened at equal intervals on the back of the lamp 17 can quickly dissipate the heat generated by the light source, avoiding excessive internal temperature from affecting the life of components. The closed cavity formed by the upper cover 12 and the lower cover 1, together with the protective function of the outer shell 25, can isolate external dust and moisture from entering, protecting the internal terminals and circuit structure.

[0042] When the lamp needs to be replaced or maintained, first press the lamp spring clip 24 to remove the outer shell 25 from the mounting base, rotate the lamp 17 in the opposite direction so that the protrusion 16 slides along the longitudinal groove of the L-shaped slot 22 to the transverse slot, and then pull the lamp upward. At this time, the terminal B19 disengages from the concave groove 13 along with the lamp, and the circuit connection between the terminal B19 and the terminal A is automatically disconnected. If the internal structure needs to be inspected, the screws between the fixing posts A and B can be removed, the upper cover 12 and the lower cover 1 can be separated, and the terminal A, wiring harness and other components can be maintained.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
