Description

Technical Field

[0001] This utility model relates to a downlight, and more particularly to a downlight with a multifunctional housing. Background Technology

[0002] Downlights have advantages such as compact structure, concealed installation, and concentrated light, and are therefore widely used in various buildings. However, the overly complex structural design of existing downlights increases the complexity of their installation process. Consequently, the cost of existing downlights has remained high.

[0003] In addition, the existing heat dissipation structure of downlights has obvious design limitations, resulting in poor heat dissipation performance. Therefore, the heat dissipation performance of existing downlights needs further improvement.

[0004] Furthermore, existing downlights lack proper anti-glare design, resulting in excessively noticeable light spots that fail to achieve optimal anti-glare effects. This severely impacts the lighting performance of these downlights, making them unsuitable for practical applications. Utility Model Content

[0005] According to one embodiment of the present invention, a downlight with a multifunctional housing is provided, comprising a housing, a light source plate, and a lampshade. The housing has a reflective part, a light-emitting part, and a buffer part. The reflective part has an annular protrusion. The annular protrusion is disposed within the reflective part and has a light inlet and a light outlet respectively disposed at its two ends. The reflective part is connected to the buffer part through the light-emitting part, so that the reflective part, the light-emitting part, and the buffer part are integrally formed. The light source plate has multiple light sources. The light source plate is disposed on one side of the reflective part, so that the multiple light sources are located within the light inlets. The lampshade is disposed within the light-emitting part and covers the light outlet.

[0006] In one embodiment, the inner diameter of the annular protrusion increases toward the light-emitting portion.

[0007] In one embodiment, the cross-section of the annular protrusion is curved.

[0008] In one embodiment, the downlight further includes an anti-glare ring. The anti-glare ring is detachably disposed within the buffer section, and the inner surface of the anti-glare ring has a plurality of anti-glare protrusions.

[0009] In one embodiment, the buffer portion further includes an annular portion. The annular portion is disposed at the end of the buffer portion away from the light-emitting portion.

[0010] In one embodiment, the downlight further includes a plurality of spring clips. The reflector also has a plurality of fixing slots corresponding to the plurality of spring clips. The plurality of spring clips are respectively disposed in the plurality of fixing slots.

[0011] In one embodiment, each spring is curved, so that the cross-section of the spring has a curved curve.

[0012] In one embodiment, each spring has a fixing hook at one end and a mounting piece at the other end. The mounting piece has a main latch. A first angle, which is acute, is formed between the main latch and the mounting piece. The mounting piece is inserted into the corresponding fixing slot.

[0013] In one embodiment, the mounting piece also has a protrusion adjacent to the main latch.

[0014] In one embodiment, the downlight further includes a power module. The power module is disposed on the light source board and is electrically connected to the plurality of light sources.

[0015] As described above, the downlight with a multi-functional housing according to the embodiments of this utility model may have one or more of the following advantages: (1) In one embodiment of this utility model, the downlight includes a housing, a light source plate, and a lampshade. The housing has a reflective part, a light-emitting part, and a buffer part. The reflective part has an annular protrusion. The annular protrusion is disposed within the reflective part and has a light inlet and a light outlet respectively disposed at its two ends. The reflective part is connected to the buffer part through the light-emitting part, so that the reflective part, the light-emitting part, and the buffer part are integrally formed. The light source plate has multiple light sources. The light source plate is disposed on one side of the reflective part, so that the multiple light sources are located within the light inlet. The lampshade is disposed within the light-emitting part and covers the light outlet. As can be seen from the above, the housing has a reflective part, a light-emitting part, and a buffer part, and the reflective part, the light-emitting part, and the buffer part are integrally formed. In this way, the housing can have a reflective function, without the need to install an additional reflector cup, which can effectively reduce the structural complexity, reduce the cost of the downlight, and improve the efficiency of the downlight assembly process.

[0016] (2) In one embodiment of this utility model, since the light source board is located on one side of the reflective part, and the multiple light sources of the light source board are located on one side of the circuit board and within the light entrance of the annular protrusion, the other side of the circuit board is completely exposed. Through the above-mentioned open heat dissipation structure design, the heat generated by the light source board can be quickly dissipated, thereby improving the heat dissipation effect of the downlight. In this way, the downlight does not need to be equipped with a fan and is not prone to failure or damage due to overheating, thus effectively extending the service life of the downlight. In addition, the downlight can also achieve the effects of quiet operation and energy saving.

[0017] (3) In one embodiment of this utility model, the inner diameter of the annular protrusion increases towards the light-emitting part, and the cross-section of the annular protrusion is curved. The above-mentioned structural design of the annular protrusion can further optimize the reflective effect to improve the lighting effect of the downlight. Therefore, the overall lighting efficiency of the downlight can also be greatly improved, enabling the downlight to meet the needs of practical applications.

[0018] (4) In one embodiment of this utility model, the downlight further includes an anti-glare ring. The anti-glare ring is detachably disposed within the buffer section. The inner surface of the anti-glare ring has multiple anti-glare protrusions, which can effectively improve the uniformity of the light spot to optimize the anti-glare effect. In addition, through the design of the detachable anti-glare ring, the user can install the anti-glare ring on the buffer section of the housing to improve the anti-glare effect of the downlight. If the anti-glare effect is not required, the user can also remove the anti-glare ring. Therefore, the downlight not only achieves the anti-glare effect but also meets the needs of different applications.

[0019] (5) In one embodiment of this utility model, the downlight further includes multiple spring clips. The reflector also has multiple fixing slots corresponding to the multiple spring clips. The multiple spring clips are respectively disposed in the multiple fixing slots. Each spring clip is curved, so that the cross-section of the spring clip is curved. One end of each spring clip has a fixing hook, and the other end of the spring clip has a mounting piece, which is inserted into the corresponding fixing slot. In this way, the downlight can be mounted on the ceiling mounting bucket through the multiple spring clips. Therefore, the installation procedure of the downlight can be greatly simplified, and it is not easy to fall off.

[0020] (6) In one embodiment of this utility model, the mounting piece has a main hook. A first included angle exists between the main hook and the mounting piece, and this first included angle is acute. The mounting piece also has a protrusion, which is adjacent to the main hook. Through the structural design of the mounting piece, the main hook prevents the mounting piece from falling out of the fixed slot, while the protrusion prevents the mounting piece from shaking within the fixed slot. As can be seen from the above, through the anti-shaking self-locking structure formed by the adjacent main hooks and protrusions, the mounting piece is not easily detached from the fixed slot, and the mounting piece is not easily shaken within the fixed slot, thus achieving a stable structure. Therefore, the overall structural stability of the downlight is significantly improved.

[0021] (7) In one embodiment of this utility model, the downlight also includes a first DIP switch and a second DIP switch, which can be mounted on the light source plate. The first DIP switch has a first switch cover, and the handle of the first DIP switch can protrude from the housing, while the first switch cover is fixed to the handle of the first DIP switch, so that the first switch cover is exposed outside the housing. The second DIP switch has a second switch cover, and the handle of the second DIP switch can protrude from the housing, while the second switch cover is fixed to the handle of the second DIP switch, so that the second switch cover is exposed outside the housing. The first DIP switch can be a color temperature switch, and the second DIP switch can be a power switch. In this way, the user can adjust the color temperature or power of the downlight according to their own needs by operating the DIP switch. Therefore, the downlight is more flexible in use and can be more widely applied to meet the needs of different users. Attached Figure Description

As shown in the figure, the downlight 1 includes a housing 11, a light source plate 12, a lampshade 13, an anti-glare ring 14, three spring contacts 15, a power module 16, a first DIP switch 17A, a second DIP switch 17B, and an electrical connection wire 18.

[0034] The housing 11 has a reflective part 111, a light-emitting part 112, and a buffer part 113. The reflective part 111 is connected to the buffer part 113 through the light-emitting part 112, so that the reflective part 111, the light-emitting part 112, and the buffer part 113 are integrally formed. The reflective part 111 has an annular protrusion 1111, three fixing slots 1112, two fixing posts 1113 (each fixing post 1113 has a screw hole at one end), and two fasteners 1114 (such as screws, bolts, etc.). The annular protrusion 1111 is disposed inside the reflective part 111. The annular protrusion 1111 has a light inlet LE and a light outlet LT respectively disposed at its two ends. The inner diameter of the annular protrusion 1111 increases towards the light-emitting part 112, and the cross-section of the annular protrusion 1111 is curved. The three fixing slots 1112 are evenly distributed on the outer surface of the reflective part 111. The two fixing posts 1113 are disposed within the reflective part 111. The inner surface of the buffer part 113 is flat (the cross-section of the buffer part 113 consists of two symmetrical straight lines), and the buffer part 113 also has an annular part 1131. The annular part 1131 is disposed at the end of the buffer part 113 away from the light-emitting part 112. The inner surface of the housing 11 can be polished. In one embodiment, the housing 11 can be made of plastic or metal (such as copper, aluminum, iron, stainless steel, etc.).

[0035] The light source board 12 has a circuit board 122 and a plurality of light sources 121 disposed on the circuit board 122. The light source board 12 is disposed on one side of the reflector 111, such that the plurality of light sources 121 are located within the light entrance LE. The number of the plurality of light sources 121 can be 10, 20, or 30, depending on actual needs. The light source board 12 is fixed to the plurality of fixing posts 1113 by the two fixing members 1114 (the two fixing members 1114 can pass through corresponding holes on the light source board 12 and be locked to the two fixing posts 1113). The number of these fixing posts 1113 can be adjusted according to actual needs and is not limited to two; in another embodiment, the number of these fixing posts 1113 can also be one or more, and the number of fixing members 1114 is equal to the number of fixing posts 1113. In one embodiment, the plurality of light sources 121 can be light-emitting diodes. In another embodiment, the plurality of light sources 121 can also be light bulbs or other similar components.

[0036] A lampshade 13 is disposed within the light-emitting section 112 and covers the light outlet LT. The bottom of the lampshade 13 has a first retaining ring F1. The inner wall of the light-emitting section 112 has three first fixing hooks G1. The three first retaining rings F1 can engage with the three first fixing hooks G1, allowing the lampshade 13 to be detachably fixed within the light-emitting section 112. The number of these first fixing hooks G1 can be adjusted according to actual needs and is not limited to three; in another embodiment, the number of these first fixing hooks G1 can also be two or four or more. In one embodiment, the lampshade 13 can be made of a transparent or translucent material, such as plastic or glass.

[0037] An anti-glare ring 14 is detachably disposed within a buffer portion 113. The inner surface of the anti-glare ring 14 has multiple anti-glare protrusions PR. The bottom of the anti-glare ring 14 has a second retaining ring F2. The inner wall of the buffer portion 113 has three second fixing hooks G2. The second retaining rings F2 can engage with the three second fixing hooks G2, thereby detachably fixing the anti-glare ring 14 within the buffer portion 113. The number of these second fixing hooks G2 can be adjusted according to actual needs and is not limited to three; in another embodiment, the number of these second fixing hooks G2 can also be two or four or more. In one embodiment, the anti-glare ring 14 can be made of plastic or other similar materials.

[0038] The three spring clips 15 are respectively disposed within the plurality of fixing slots 1112. Each spring clip 15 is curved, so that the cross-section of the spring clip 15 is curved. Each spring clip 15 is inserted into the corresponding fixing slot 1112 to be fixed thereon. In this way, the spring clip 15 provides the function of a hook. The three spring clips 15 can be made of a flexible material, such as metal (copper, aluminum, iron or stainless steel) or plastic. The number of these spring clips 15 can be adjusted according to actual needs and is not limited to three; in another embodiment, the number of these spring clips 15 can also be two or four or more, and the number of fixing slots 1112 is equal to the number of spring clips 15.

[0039] The power module 16 is disposed on the circuit board 122 and is electrically connected to the plurality of light sources 121. In one embodiment, the power module 16 may be a light-emitting diode driver. In another embodiment, the power module 16 may also be a power supply for other existing light sources.

[0040] The first DIP switch 17A and the second DIP switch 17B are mounted on the circuit board 122 and electrically connected to the power module 16. The first DIP switch 17A has a first switch cover C1, and its handle protrudes from the housing 11. The first switch cover C1 is fixed to the handle of the first DIP switch 17A, thus exposing the first switch cover C1 within the housing 11. The second DIP switch 17B has a second switch cover C2, and its handle protrudes from the housing 11. The second switch cover C2 is fixed to the handle of the second DIP switch 17B, thus exposing the second switch cover C2 within the housing 11. The first DIP switch 17A can be a color temperature switch, and the second DIP switch 17B can be a power switch. Users can adjust the color temperature and / or power of the downlight 1 by operating the first DIP switch 17A and / or the second DIP switch 17B to meet different application requirements. In another embodiment, the first DIP switch 17A can be a brightness switch, while the second DIP switch 17B can be a color temperature switch, which can be adjusted according to actual needs to provide different lighting adjustment functions.

[0041] One end of the electrical connection wire 18 can pass through the hole in the circuit board 122 and be electrically connected to the power module 16, while the other end of the electrical connection wire 18 can be connected to an external power source, such as mains power or other power sources (such as a generator).

[0042] When the downlight 1 is not equipped with the anti-glare ring 14, the light emitted by the light source plate 12 can be reflected by the reflective part 111 (annular protrusion 1111) of the housing 11, and then irradiated outward through the buffer part 113 of the housing 11. The curved surface design of the annular protrusion 1111 and the planar inner surface design of the buffer part 113 can make the light more uniform and softer. When the downlight 1 is not equipped with the anti-glare ring 14, the anti-glare ring 14 can improve the uniformity of the light spot, thereby improving the anti-glare effect of the downlight 1.

[0043] As described above, in this embodiment, the housing 11 adopts a one-piece molding design, integrating three functional parts: the reflector 111, the light-emitting part 112, and the buffer part 113. This one-piece molding design allows the housing 11 itself to have light reflection function, eliminating the need for an additional reflector cup. This not only simplifies the structure of the downlight 1 and reduces production costs but also significantly improves the assembly efficiency of the downlight 1. By integrating multiple functional components into a single component, both optical performance and manufacturing costs are optimized.

[0044] Furthermore, in this embodiment, since the light source plate 12 is disposed on one side of the reflector 111, and the multiple light sources 121 of the light source plate 12 are disposed on one side of the circuit board 122 and located within the light entrance LE of the annular protrusion 1111, the other side of the circuit board 122 is completely exposed. Through the aforementioned open heat dissipation structure design, the heat generated by the light source plate 12 can be quickly dissipated, thereby improving the heat dissipation effect of the downlight 1. Thus, the downlight 1 does not require a fan and is less prone to malfunction or damage due to overheating, effectively extending its service life. In addition, the downlight 1 also achieves quiet operation and energy saving.

[0045] Furthermore, in this embodiment, the inner diameter of the annular protrusion 1111 increases towards the light-emitting portion 112, and the cross-section of the annular protrusion 1111 consists of two symmetrical curves. This structural design of the annular protrusion 1111 further optimizes the reflective effect, thereby improving the illumination effect of the downlight 1. Therefore, the overall illumination efficiency of the downlight 1 can be significantly improved, enabling the downlight 1 to meet the needs of practical applications.

[0046] In addition, in this embodiment, the downlight 1 also includes an anti-glare ring 14. The anti-glare ring 14 is detachably disposed within the buffer portion 113. The inner surface of the anti-glare ring 14 has multiple anti-glare protrusions PR. The surface of each anti-glare protrusion PR is curved, which can effectively improve the uniformity of the light spot to optimize the anti-glare effect. Furthermore, due to the design of the detachable anti-glare ring 14, the user can install the anti-glare ring 14 on the buffer portion 113 of the housing 11 to improve the anti-glare effect of the downlight 1. If the anti-glare effect is not required, the user can also remove the anti-glare ring 14. Therefore, the downlight 1 not only achieves the anti-glare effect but also meets the needs of different applications.

[0047] Furthermore, in this embodiment, the downlight 1 also includes three spring clips 15. The reflector 111 also has multiple fixing slots 1112 corresponding to the three spring clips 15. The three spring clips 15 are respectively disposed in the three fixing slots 1112. Each spring clip 15 is curved, so that the cross-section of the spring clip 15 is curved. In this way, the downlight 1 can be mounted on the ceiling mounting bracket through the multiple spring clips. Therefore, the installation procedure of the downlight 1 can be greatly simplified, and it is not easy to fall off.

[0048] Of course, this embodiment is only for illustrative purposes and is not intended to limit the scope of this utility model. Equivalent modifications or changes made to the downlight 1 with a multifunctional housing according to this embodiment should still be included within the patent scope of this utility model.

[0049] It is worth mentioning that downlights have advantages such as compact structure, concealed installation, and concentrated light, and are therefore widely used in various buildings. However, existing downlights suffer from overly complex structural designs, which also increases the complexity of their installation processes. Therefore, the cost of existing downlights remains high. Furthermore, the heat dissipation structure of existing downlights has significant design limitations, resulting in poor heat dissipation. Therefore, the heat dissipation effect of existing downlights needs further improvement. In addition, existing downlights lack appropriate anti-glare design, resulting in overly noticeable light spots that fail to achieve optimal anti-glare effects, severely impacting their lighting performance and making them unsuitable for practical applications. In contrast, according to an embodiment of this utility model, the downlight includes a housing, a light source plate, and a lampshade. The housing has a reflective part, a light-emitting part, and a buffer part. The reflective part has an annular protrusion. The annular protrusion is disposed within the reflective part and has light inlets and light outlets respectively disposed at its two ends. The reflective part is connected to the buffer part through the light-emitting part, making the reflective part, light-emitting part, and buffer part integrally formed. The light source plate has multiple light sources. The light source plate is positioned on one side of the reflector, placing the multiple light sources within the light inlet. The lampshade is located within the light-emitting section and covers the light outlet. As described above, the housing comprises a reflector, a light-emitting section, and a buffer section, all integrally formed. This allows the housing to function as a reflector without requiring an additional reflector cup, effectively reducing structural complexity, lowering the cost of the downlight, and improving the efficiency of the assembly process.

[0050] Furthermore, according to an embodiment of this utility model, since the light source board is located on one side of the reflective part, and the multiple light sources of the light source board are located on one side of the circuit board and within the light entrance of the annular protrusion, the other side of the circuit board is completely exposed. Through the aforementioned open heat dissipation structure design, the heat generated by the light source board can be quickly dissipated, thereby improving the heat dissipation effect of the downlight. Thus, the downlight does not require a fan and is less prone to malfunction or damage due to overheating, effectively extending its lifespan. In addition, the downlight also achieves quiet operation and energy saving.

[0051] Furthermore, according to embodiments of this invention, the inner diameter of the annular protrusion increases towards the light-emitting portion, and the cross-section of the annular protrusion consists of two symmetrical curves. This structural design of the annular protrusion further optimizes the reflective effect, thereby enhancing the lighting effect of the downlight. Therefore, the overall lighting efficiency of the downlight can be significantly improved, enabling it to meet the needs of practical applications.

[0052] Furthermore, according to embodiments of this utility model, the downlight also includes an anti-glare ring. The anti-glare ring is detachably disposed within the buffer section. The inner surface of the anti-glare ring has multiple anti-glare protrusions, which can effectively improve the uniformity of the light spot to optimize the anti-glare effect. Additionally, due to the detachable design of the anti-glare ring, the user can install the anti-glare ring on the buffer section of the housing to enhance the anti-glare effect of the downlight. If the anti-glare effect is not required, the user can also remove the anti-glare ring. Therefore, the downlight not only achieves an anti-glare effect but also meets the needs of different applications.

[0053] Furthermore, according to an embodiment of this utility model, the downlight also includes a first DIP switch and a second DIP switch, which can be mounted on the light source plate. The first DIP switch has a first switch cover, and the handle of the first DIP switch can protrude from the housing. The first switch cover is fixed to the handle of the first DIP switch, making the first switch cover exposed outside the housing. The second DIP switch has a second switch cover, and the handle of the second DIP switch can protrude from the housing. The second switch cover is fixed to the handle of the second DIP switch, making the second switch cover exposed outside the housing. The first DIP switch can be a color temperature switch, and the second DIP switch can be a power switch. In this way, the user can adjust the color temperature or power of the downlight according to their own needs by operating the DIP switches. Therefore, the downlight is more flexible in use and has a wider range of applications to meet the needs of different users. As can be seen from the above, the downlight with a multi-functional housing according to the embodiment of this utility model can indeed achieve excellent technical effects.

[0054] Please see Figure 7 and Figure 8 . Figure 7 This is a perspective view of the spring clip of a downlight with a multifunctional housing according to an embodiment of the present invention. Figure 8 A side view of the spring contacts of a downlight with a multi-functional housing according to an embodiment of this utility model. As shown, each spring contact 15 has a fixing hook 151 at one end and a mounting piece 152 at the other end. The mounting piece 152 is inserted into a corresponding fixing slot 1112. The mounting piece 152 has a main hook MH and a protrusion AH. The protrusion AH is adjacent to the main hook MH. There is a first included angle θ1 between the main hook MH and the mounting piece 152. The first included angle θ1 is an acute angle; the first included angle θ1 can be 10~50°, such as 45°, 40° or 30°. In another embodiment, the number of protrusions AH can be two or more.

[0055] When the mounting piece 152 is inserted into the corresponding fixing slot 1112, the main hook MH is pressed against the inner wall of the fixing slot 1112 and then embedded into the hole in the inner wall of the fixing slot 1112. Furthermore, the top of the protrusion AH abuts against the inner wall of the fixing slot 1112. Through the structural design of the mounting piece 152, the main hook MH prevents the mounting piece from falling out of the fixing slot 1112. Additionally, the protrusion AH prevents the mounting piece 152 from wobbling within the fixing slot 1112, thus achieving structural stability.

[0056] As described above, through the anti-shake self-locking structure formed by the adjacent main hooks MH and the protrusion AH, the mounting piece 152 is not easily dislodged from the fixing slot 1112, and the mounting piece 152 is also not easily shaken within the fixing slot 1112. Thus, a greater force is required to separate the spring piece 15 from the fixing slot 1112. This structural design makes it almost impossible for the mounting piece 152 to accidentally dislodge under normal use conditions; a greater force is required to separate the spring piece 15 from the fixing slot 1112. Furthermore, the force by which the mounting piece 152 and the fixing slot 1112 are fixed together, along with the design of the protrusion AH, achieves a stable structure. Therefore, the overall structural stability of the downlight 1 is significantly improved.

[0057] Of course, this embodiment is only for illustrative purposes and is not intended to limit the scope of this utility model. Equivalent modifications or changes made to the downlight 1 with a multifunctional housing according to this embodiment should still be included within the patent scope of this utility model.

[0058] In summary, according to the embodiments of this utility model, the downlight includes a housing, a light source plate, and a lampshade. The housing has a reflective part, a light-emitting part, and a buffer part. The reflective part has an annular protrusion. The annular protrusion is disposed within the reflective part and has a light inlet and a light outlet respectively disposed at its two ends. The reflective part is connected to the buffer part through the light-emitting part, so that the reflective part, the light-emitting part, and the buffer part are integrally formed. The light source plate has multiple light sources. The light source plate is disposed on one side of the reflective part, so that the multiple light sources are located within the light inlets. The lampshade is disposed within the light-emitting part and covers the light outlet. As can be seen from the above, the housing has a reflective part, a light-emitting part, and a buffer part, and the reflective part, the light-emitting part, and the buffer part are integrally formed. In this way, the housing can have a reflective function without the need to install an additional reflector cup, which can effectively reduce structural complexity, reduce the cost of the downlight, and improve the efficiency of the downlight assembly process.

[0059] According to an embodiment of this utility model, since the light source board is located on one side of the reflective part, and the multiple light sources of the light source board are located on one side of the circuit board and within the light entrance of the annular protrusion, the other side of the circuit board is completely exposed. Through the above-described open heat dissipation structure design, the heat generated by the light source board can be quickly dissipated, thereby improving the heat dissipation effect of the downlight. Thus, the downlight does not require a fan and is less prone to malfunction or damage due to overheating, effectively extending its lifespan. Furthermore, the downlight also achieves quiet operation and energy saving.

[0060] According to an embodiment of this utility model, the inner diameter of the annular protrusion increases towards the light-emitting part, and the cross-section of the annular protrusion consists of two symmetrical curves. This structural design of the annular protrusion further optimizes the reflective effect, thereby improving the lighting effect of the downlight. Therefore, the overall lighting efficiency of the downlight can be significantly improved, enabling it to meet the needs of practical applications.

[0061] Furthermore, according to an embodiment of this utility model, the downlight also includes an anti-glare ring. The anti-glare ring is detachably disposed within the buffer section. The inner surface of the anti-glare ring has multiple anti-glare protrusions, which can effectively improve the uniformity of the light spot to optimize the anti-glare effect. In addition, due to the design of the detachable anti-glare ring, the user can install the anti-glare ring on the buffer section of the housing to enhance the anti-glare effect of the downlight. If the anti-glare effect is not required, the user can also remove the anti-glare ring. Therefore, the downlight not only achieves an anti-glare effect but also meets the needs of different applications.

[0062] Furthermore, according to an embodiment of this utility model, the downlight also includes multiple spring clips. The reflector also has multiple fixing slots corresponding to the multiple spring clips. The multiple spring clips are respectively disposed in the multiple fixing slots. Each spring clip is curved, so that the cross-section of the spring clip has a curved curve. One end of each spring clip has a fixing hook, and the other end of the spring clip has a mounting piece, which is inserted into the corresponding fixing slot. In this way, the downlight can be mounted on a mounting bucket on the ceiling through the multiple spring clips. Therefore, the installation procedure of the downlight can be greatly simplified, and it is not easy to fall off.

[0063] Furthermore, according to an embodiment of this utility model, the mounting plate has a main hook. A first included angle, which is acute, is formed between the main hook and the mounting plate. The mounting plate also has a protrusion adjacent to the main hook. Through the structural design of the mounting plate, the main hook prevents the mounting plate from falling out of the fixing slot, while the protrusion prevents the mounting plate from wobbling within the fixing slot. As can be seen from the above, through the anti-wobbling self-locking structure formed by the adjacent main hooks and protrusions, the mounting plate is less likely to fall out of the fixing slot and is less likely to wobble within the fixing slot, thus achieving a stable structure. Therefore, the overall structural stability of the downlight is significantly improved.

[0064] Furthermore, according to an embodiment of this utility model, the downlight also includes a first DIP switch and a second DIP switch, which can be mounted on the light source plate. The first DIP switch has a first switch cover, and the handle of the first DIP switch can protrude from the housing, while the first switch cover is fixed to the handle of the first DIP switch, making the first switch cover exposed outside the housing. The second DIP switch has a second switch cover, and the handle of the second DIP switch can protrude from the housing, while the second switch cover is fixed to the handle of the second DIP switch, making the second switch cover exposed outside the housing. The first DIP switch can be a color temperature switch, and the second DIP switch can be a power switch. In this way, users can adjust the color temperature or power of the downlight according to their own needs by operating the DIP switches. Therefore, the downlight is more flexible in its use and has a wider range of applications to meet the needs of different users.

[0065] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
