Technical Field
[0001] The utility model belongs to the technical field of lamps, and particularly relates to a downlight. Background Art
[0002] A downlight is a kind of lamp suitable for indoor lighting. This recessed lamp installed inside the ceiling projects all light downward, belonging to direct light distribution.
[0003] Traditional downlights may not use efficient heat dissipation materials or designs, resulting in the inability to effectively conduct heat from inside the bulb to the outside. Heat accumulates inside the bulb, increasing the working temperature of the bulb. Traditional downlights may lack a large enough heat dissipation area or the heat dissipation material is not properly selected, and cannot effectively dissipate the heat generated by the bulb into the surrounding environment, resulting in heat accumulation. The air fluidity inside the downlight is poor, or the heat dissipation design does not consider the guidance of air flow, making the hot air unable to be discharged in time, affecting the heat dissipation effect.
[0004] To overcome these defects, we propose a downlight. Content of the Utility Model
[0005] The present invention aims to solve the technical problem in the above-mentioned prior art that there is no effective heat dissipation design, resulting in too high a temperature of the bulb and shortening the service life.
[0006] To achieve the above object, the utility model provides the following technical solutions:

A plurality of conical ribs are arranged annularly and equidistantly on the outer side of the annular rib, and each conical rib is inserted into the space formed by adjacent two mountain-shaped ribs and the arc-shaped rib.

The end of the spring buckle position is connected with a limiting plate, and the limiting plate is provided with a buckle groove position for cooperating with the spring buckle position to be buckled and limited with the installation groove position on the installation platform of the downlight.
[0011] Preferably, a connecting circular wire connected to the electrical components inside the connecting seat is provided on the bottom surface of the connecting seat.
[0012] The design of the connecting circular wire simplifies the circuit layout between the electrical components and the connecting seat.
[0013] Preferably, lamp beads connected to the electrical components are provided in the middle of the face ring on the front surface of the lamp body, and a reflecting cup is provided on the outer edge of the lamp body corresponding to the lamp beads;
[0014] A lens covering the lamp beads and located at the top of the opening of the reflecting cup is provided on the lamp body.
[0015] The light emitted by the lamp beads can provide a more uniform and concentrated lighting effect through the refraction of the reflecting cup and the focusing of the lens.

[0020] Compared with the prior art, the technical effects and advantages of the present utility model are:
[0021] By providing unique heat dissipation rib strips on the bottom surface and side surface of the connecting seat, this downlight achieves efficient heat dissipation and structural enhancement. The heat dissipation rib strips on the bottom surface are composed of annular rib strips, mountain-shaped rib strips, and arc-shaped rib strips, forming a structure for heat conduction and air flow, effectively improving the heat dissipation efficiency and the mechanical strength of the connecting seat. The rib strips on the side surface increase the heat dissipation area, help evenly distribute heat, maintain the temperature balance inside the lamp body, and enhance the stability of the connecting seat.

Structurally, the design of the side ribs increases the mechanical strength of the connection base while optimizing the heat dissipation efficiency and appearance. The thickness variation of the side ribs and the heat dissipation ribs also improves the structural stability and heat dissipation efficiency. Generally speaking, this design combines the principles of mechanics, electricity, optics, and thermotics, achieving the high efficiency, stability, and aesthetics of the downlight.

Detailed Embodiment
[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0028] The following is a further detailed description of this application in conjunction with the attached Figures 1-3 to further illustrate this application in detail.
[0029] An embodiment of the present application discloses a downlight, which includes a lamp body 1 and a connection base 2 provided at the connection end of the lamp body 1 for assembling electrical components inside the lamp body 1. A flange 19 is provided at the connection between the connection base 2 and the lamp body 1, and the connection base 2 is fixed to the lamp body 1 through the perforated mounting posts 20 on the flange 19 and screws 21. The design of the flange 19 and the perforated mounting posts 20 provides a mechanical connection with the lamp body 1. Fastened by the screws 21, the stability of the connection base 2 and the safety of the lamp body 1 are ensured. Fixed to the lamp body 1 by the screws 21, users can conveniently carry out installation and maintenance work, improving the convenience of operation. The design of the flange 19 can increase the wear resistance and anti-deformation ability of the connection base 2, extending the service life of the product.
[0030] On opposite sides of the connection base 2, there are spring catch positions 11 connected by a torsion spring 9 and a positioning block 10 respectively. The end of the spring catch position 11 is connected with a limiting plate 12, and a snap groove 13 for cooperating with the spring catch position 11 to be snap-connected and limited to the mounting groove on the installation platform of the downlight is provided on the limiting plate 12. The design of the spring catch position 11 and the limiting plate 12 enables the downlight to be easily installed on and removed from the installation platform, providing a convenient installation experience. Through the cooperation of the spring catch position 11 and the snap groove 13 of the limiting plate 12, it can be ensured that the downlight remains stable after installation, reducing loosening caused by vibration or movement. The design of the limiting plate 12 and the snap groove 13 ensures that the downlight does not slide during the installation process, thus improving the safety during use.
[0031] On the bottom surface of the connection base 2, there is a connecting round wire 14 connected to the electrical components inside the connection base 2.
[0032] The design of the connecting round wire 14 simplifies the circuit layout between the electrical components and the connection base 2.
[0033] In the middle of the face ring 15 on the front surface of the lamp body 1, there is a lamp bead 16 connected to the electrical components, and a reflecting cup 17 is provided on the outer edge of the lamp body 1 corresponding to the lamp bead 16; a lens 18 covering the lamp bead 16 and located at the top of the opening of the reflecting cup 17 is provided on the lamp body 1.
[0034] The light emitted by the lamp bead 16 can provide a more uniform and concentrated lighting effect through the refraction of the reflecting cup 17 and the focusing of the lens 18. This design of the lamp body 1 not only has practical functions but also increases the aesthetics of the product, enhancing the overall visual effect. The design of the lens 18 can control the emission angle and distribution of the light, enabling the light to better adapt to different lighting requirements. By optimizing the light distribution, the waste of light energy can be reduced, the energy efficiency of the light source can be improved, and the energy consumption can be lowered.
[0035] On the bottom surface of the connection base 2, there are heat dissipation ribs 3 protruding from the surface of the connection base 2.
[0036] The heat dissipation rib 3 includes an annular rib 4 located in the middle of the bottom surface of the connection base 2, a plurality of mountain-shaped ribs 5 arranged annularly and equidistantly on the outer side of the annular rib 4 and opening outward, and an arc-shaped rib 6 connecting adjacent two mountain-shaped ribs 5. A plurality of conical ribs 7 are arranged annularly and equidistantly on the outer side of the annular rib 4, and each conical rib 7 is inserted into a vacancy 8 formed by adjacent two mountain-shaped ribs 5 and the arc-shaped rib 6.
[0037] The design of the heat dissipation rib 3 can effectively increase the heat dissipation area, accelerate the conduction and dissipation of heat, ensure that the bulb operates at a lower temperature, thereby improving the service life and maintaining the stability of the light. The structures of the annular rib 4 and the mountain-shaped rib 5 can increase the mechanical strength of the connection base 2, making the connection base 2 more firm and durable. The design of the mountain-shaped rib 5 opening outward and the arc-shaped rib 6 helps to guide the surrounding air flow, further improving the heat dissipation efficiency. This design not only focuses on functionality but also takes into account the appearance of the product. The unique rib design can make the downlight look more modern and distinctive. By optimizing the rib structure, effective heat dissipation and structural support can be achieved within a limited space, suitable for a variety of installation environments. Good heat dissipation performance can reduce the safety risks caused by overheating of the lamp.
[0038] A plurality of side ribs 22 for heat dissipation are evenly distributed around the circumference on the side surface of the connection base 2.
[0039] The side ribs 22 increase the heat dissipation area, help to improve the heat dissipation efficiency, reduce the temperature inside the lamp body 1, thereby prolonging the service life of the electrical components. The side ribs 22 help to evenly distribute the heat generated inside the lamp body 1, avoid local overheating, and maintain the overall temperature balance of the lamp body 1. The side ribs 22 not only help with heat dissipation but also can enhance the mechanical strength of the connection base 2 and improve the overall structural stability.
[0040] The thicknesses of the conical rib 7, the mountain-shaped rib 5, and the arc-shaped rib 6 gradually decrease from inside to outside.
[0041] The thickness change from inside to outside helps with the rapid conduction and dissipation of heat, further improving the heat dissipation efficiency. The gradual decrease in thickness can reduce the use of materials, thereby reducing production costs while maintaining sufficient structural strength and heat dissipation performance.
[0042] The downlight realizes the mechanical fixation of the connection base 2 through the perforated mounting posts 20 on the flange 19 and the screws 21. It provides a stable mechanical connection, is convenient for installation and maintenance, and increases the wear resistance and anti-deformation ability. The downlight is tightly connected to the installation platform through the snap positions 11 of the spring and the snap slots 13 of the limit plate 12. The convenient installation and disassembly ensure the stability after installation and prevent loosening caused by vibration or movement.
[0043] The design of the heat dissipation ribs 3, by increasing the heat dissipation area and optimizing heat conduction, keeps the bulb operating at a lower temperature. It improves the service life of the lamp, prevents safety risks brought by overheating, and may also help improve the stability of the lamp. The design of the side ribs 22 increases the heat dissipation area, improves the heat dissipation efficiency, evenly distributes heat, and enhances the structural stability. It further reduces the internal temperature of the lamp body 1, extends the service life of the electrical components, and maintains the overall temperature balance of the lamp body 1. The heat conduction and heat dissipation efficiency are optimized by gradually reducing the thickness of the ribs. It reduces the material usage, lowers the production cost, while maintaining sufficient structural strength and heat dissipation performance.
[0044] These design features together constitute the downlight, which not only improves the functionality of the product, but also takes into account the convenience of installation and maintenance as well as cost-effectiveness, making the product more in line with market demands.
[0045] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
