Description

Technical Field

[0001] This utility model relates to the field of lighting fixture technology, specifically to a magnetically assembled downlight reflector. Background Technology

[0002] Downlights are a common type of lighting fixture and are widely used in various indoor places. As an important component of downlights, the reflector of downlights mainly reflects and redistributes the light emitted by the light source to improve the lighting effect and light utilization. However, existing downlight reflectors have many shortcomings in structural design and installation methods.

[0003] Traditional downlight reflector installation methods are usually quite complex, often using screw fixing or clip connections. Screw fixing requires tools, is time-consuming to install, and is also cumbersome to disassemble, making it difficult to maintain and replace later. Clip connections are prone to loosening and damage over long-term use, resulting in unstable reflector installation and affecting lighting performance. Furthermore, traditional reflectors are mostly one-piece structures, taking up a lot of space during transportation and storage. When a part of the reflector is damaged, the entire reflector needs to be replaced, resulting in wasted resources. Utility Model Content

[0004] The purpose of this utility model is to provide a magnetically assembled downlight reflector to solve the problems mentioned in the background art, which are that the traditional downlight reflector installation methods are usually complicated, the screw installation takes too long to disassemble and assemble, and the clip installation is prone to loosening after long-term use. In addition, most traditional reflectors are integral structures, which occupy a lot of space during transportation and storage. When a part of the reflector is damaged, the whole reflector needs to be replaced, resulting in a waste of resources.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a magnetically assembled downlight reflector, including a spotlight body, which is the main body of the downlight light source, and a heat dissipation cover is fitted over the spotlight body, and the heat dissipation cover and the connecting base are installed to form the main structure of the downlight.

[0006] The upper end of the connecting base is provided with an annular protrusion structure that engages with the bottom end of the heat sink, and the side wall of the connecting base is provided with an annular plate structure, and the bottom end of the side wall of the connecting base is provided with a thread. The bottom end of the annular plate of the connecting base is provided with limit posts at equal intervals, and the limit posts penetrate the auxiliary ring. The auxiliary ring is connected to the thread on the side wall of the connecting base.

[0007] The bottom end of the auxiliary ring is equipped with reflector segments, and there are 4 reflector segments. The upper end of the reflector segments is threadedly connected to the positioning bolt. Magnetic suction plates are equidistantly arranged at the bottom end of the auxiliary ring, and magnetic suction plates abut against each other. Magnetic suction plates are installed on the upper end of the reflector segments, and there are 2 magnetic suction plates on the upper end of the reflector segments. The 2 magnetic suction plates are arranged on both sides of the upper end of the reflector segments.

[0008] Using the above technical solution, the downlight frame is quickly and conveniently constructed by using a connecting base that snaps into the heat sink and an auxiliary ring that is threaded into the connecting base.

[0009] Preferably, the outer layer of the heat dissipation cover is provided with a grid-like heat dissipation fin, and the bottom end of the heat dissipation cover is attracted to the connecting base by a magnetic sheet, and the bottom end of the connecting base abuts against the surface of the spotlight body.

[0010] By adopting the above technical solution, the outer grid-like heat dissipation fins increase the heat dissipation area, which can quickly dissipate the heat generated by the lamp body during operation and reduce the internal temperature of the downlight.

[0011] Preferably, the bottom height of the connecting base is lower than the bottom height of the limiting post, and a sealing element is provided at the through connection between the limiting post and the auxiliary ring.

[0012] By adopting the above technical solution, the seal at the connection between the limiting post and the auxiliary ring effectively prevents dust and moisture from entering, protecting the internal circuits and components of the downlight and improving its protective performance.

[0013] Preferably, the magnetic suction plate one is configured as a strip structure, and the magnetic suction plate one is attracted to the magnetic suction plate two disposed in the two reflector segments, and the reflector segments are configured as arc-shaped structures.

[0014] By adopting the above technical solution, the connection stability is enhanced by the attraction between a single magnetic plate and the magnetic plates within the two reflector segments, making the reflector segments more securely installed.

[0015] Preferably, each reflector segment is provided with a magnetic suction plate three on its side wall, and adjacent reflector segments are attracted to the magnetic suction plate three.

[0016] Using the above technical solution, adjacent reflector sections attract each other through the magnetic plates on the side walls, further enhancing the overall structural stability of the reflector. Even under vibration and other environments, the components remain tightly connected and are not easily loosened.

[0017] Preferably, the four reflector segments constitute a lampshade structure, and the inner wall surface of the reflector segments is coated with a reflective coating.

[0018] Using the above technical solution, four reflectors are used to form the lampshade structure. The inner wall is coated with a high reflectivity coating, which efficiently reflects and distributes light, improves light utilization, and provides users with a brighter and more uniform lighting experience.

[0019] Preferably, the positioning bolt passes through the auxiliary ring, and the bottom end of the positioning bolt is connected to the groove on the surface of the reflector segment.

[0020] By adopting the above technical solution, the positioning bolts are simultaneously inserted through the top of the reflector segments of the auxiliary ring, which enhances the connection stability between the reflector segments and the auxiliary ring, prevents the reflector segments from shaking or shifting, and ensures stable lighting effect.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the magnetically assembled downlight reflector:

[0022] 1. The basic frame of the downlight can be quickly assembled through the snap-fit ​​connection between the connecting base and the heat sink, and the threaded connection between the auxiliary ring and the connecting base. Simultaneously, the magnetic plates equidistantly positioned at the bottom of the auxiliary ring attract the magnetic plates on both sides of the upper end of the reflector segments. Combined with the threaded connection between the positioning pins and the grooves on the reflector segments, the reflector segments can be installed quickly. The annular protrusion on the connecting base snaps into the bottom of the heat sink, and the limiting post penetrates the auxiliary ring, ensuring precise positioning of each component during installation, avoiding deviations during installation, guaranteeing the stability of the overall downlight structure, and requiring no additional tools, thus improving installation efficiency.

[0023] 2. The reflector adopts a segmented design. When a segment of the reflector is damaged, simply unscrew the positioning bolt and separate the magnetic plate one from the magnetic plate two to replace the damaged segment individually without replacing the entire reflector. This significantly reduces maintenance costs. Furthermore, the magnetic connection allows the reflector to be easily disassembled when maintenance is needed, facilitating the inspection and maintenance of internal components such as the spotlight body, reducing maintenance time and difficulty.

[0024] 3. The threaded connection on the side wall of the connecting base connects to the auxiliary ring, which, together with the limiting post, ensures that the auxiliary ring can be firmly installed on the connecting base. Adjacent reflector sections attract each other through the magnetic plates on the side wall, further enhancing the overall structural stability of the reflector. Even in a vibration environment, the connection of each component can be guaranteed to be firm and not easily loosened. The sealing element set at the connection between the limiting post and the auxiliary ring can effectively prevent dust, moisture and other impurities from entering the downlight, avoiding circuit failures or component corrosion caused by the accumulation of impurities, improving the protective performance of the downlight and ensuring its long-term stable operation.

[0032] 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.

[0033] Please see Figures 1-6 This utility model provides a technical solution: a magnetically assembled downlight reflector, including a spotlight body 1, a heat sink 2, a connecting base 3, a limiting post 4, an auxiliary ring 5, a magnetic suction plate 1 6, a reflector segment 7, a magnetic suction plate 2 8, a magnetic suction plate 3 9, a positioning bolt 10, and a reflective coating 11.

[0034] Among them, the spotlight body 1 is the main body of the downlight light source. The spotlight body 1 is covered with a heat dissipation cover 2, and the heat dissipation cover 2 and the connecting base 3 are installed to form the main structure of the downlight.

[0035] The upper end of the connecting base 3 is provided with an annular protrusion structure that engages with the bottom end of the heat sink 2, and the side wall of the connecting base 3 is provided with an annular plate structure. The bottom end of the side wall of the connecting base 3 is provided with threads. Limiting posts 4 are provided at equal intervals at the bottom end of the annular plate of the connecting base 3, and the limiting posts 4 penetrate through the auxiliary ring 5. The auxiliary ring 5 is threadedly connected to the side wall of the connecting base 3. The outer layer of the heat sink 2 is provided with a grid-like heat dissipation fin plate, and the bottom end of the heat sink 2 is attracted to the connecting base 3 by a magnetic sheet. The bottom end of the connecting base 3 abuts against the surface of the spotlight body 1. The height of the bottom end of the connecting base 3 is lower than the height of the bottom end of the limiting post 4, and a sealing element is provided at the connection between the limiting post 4 and the auxiliary ring 5.

[0036] Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, the heat sink 2 is fitted onto the spotlight body 1. The heat sink 2 is made of aluminum alloy and is manufactured by die casting. It has a structure with a grid-like heat dissipation fin on the outer layer. Its large surface area can increase the contact area with air, thereby accelerating heat dissipation. The bottom end of the heat sink 2 is engaged with the annular protrusion structure on the upper end of the connecting base 3. This engagement connection ensures a stable connection between the heat sink 2 and the connecting base 3, and also provides a good path for heat conduction. The heat generated by the spotlight body 1 can be quickly transferred to the heat sink 2 and then dissipated into the surrounding environment. At the same time, the bottom end of the connecting base 3 abuts against the surface of the spotlight body 1, further ensuring the stability of the entire downlight body structure and optimizing the heat conduction process from the spotlight body 1 to the connecting base 3.

[0037] Drill holes at the bottom of the annular plate of the connecting base 3 and install the limiting post 4. When installing the auxiliary ring 5, the limiting post 4 restricts the installation position of the auxiliary ring 5 on the connecting base 3 to ensure the accuracy of the installation and prevent the auxiliary ring 5 from rotating or shifting during use. Align the through hole of the auxiliary ring 5 with the limiting post 4 and install it through. At this time, the auxiliary ring 5 is initially positioned under the guidance of the limiting post 4. Then, the auxiliary ring 5 is connected to the threaded side wall of the connecting base 3 through the thread. As the auxiliary ring 5 is tightened, the connection between it and the connecting base 3 gradually becomes tighter.

[0038] A reflector segment 7 is installed at the bottom of the auxiliary ring 5, and there are four reflector segments 7. The upper end of the reflector segment 7 is threadedly connected to the positioning bolt 10. Magnetic suction plates 6 are equidistantly arranged at the bottom of the auxiliary ring 5, and magnetic suction plates 6 abut against magnetic suction plates 8. Magnetic suction plates 8 are installed on the upper end of the reflector segment 7, and two magnetic suction plates 8 are arranged on the upper end of the reflector segment 7. The two magnetic suction plates 8 are arranged on both sides of the upper end of the reflector segment 7. The magnetic suction plates 6 are strip-shaped. The structure includes a magnetic suction plate 6 that attracts magnetic suction plates 8 set inside two reflector segments 7. The reflector segments 7 are designed with an arc shape. Magnetic suction plates 9 are set on the side walls of each reflector segment 7. Adjacent reflector segments 7 attract magnetic suction plates 9. The four reflector segments 7 form a lampshade structure. The inner wall of the reflector segments 7 is coated with a reflective coating 11. The positioning bolt 10 passes through the auxiliary ring 5, and the bottom end of the positioning bolt 10 is connected to the groove on the surface of the reflector segment 7.

[0039] Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, magnetic plates 1-6 are equidistantly installed at the bottom of the auxiliary ring 5. Magnetic plates 1-6 are made of neodymium iron boron strong magnetic material and have a strong magnetic property. Corresponding magnetic plates 2-8 are installed on both sides of the upper end of the reflector segment 7. When the reflector segment 7 is brought close to the auxiliary ring 5, magnetic plates 1-6 and magnetic plates 2-8 attract each other under the action of magnetic force, so that the reflector segment 7 is initially fixed on the auxiliary ring 5. The magnetic connection method is simple and quick to operate and can achieve the initial positioning of the reflector segment 7 without additional tools. After the four reflector segments 7 are initially installed, the adjacent reflector segments 7 are attracted to each other by magnetic plates 3-9 installed on the side wall. Magnetic plates 3-9 are also made of neodymium iron boron strong magnetic material. The magnetic force they generate makes the adjacent reflector segments 7 tightly spliced ​​together to form a complete lampshade structure.

[0040] After initial magnetic fixation, the positioning bolt 10 is passed through the auxiliary ring 5 and screwed into the groove on the surface of the reflector segment 7. The positioning bolt 10 is made of stainless steel with a threaded bolt structure. The head at one end is easy to tighten. The function of the positioning bolt 10 is to further enhance the connection stability between the reflector segment 7 and the auxiliary ring 5, prevent the reflector segment 7 from shifting or falling off due to vibration, external force or other factors during use, and ensure the reliability of the reflector during long-term use.

[0041] Working Principle: When using this magnetically assembled downlight reflector, the downlight body consists of a spotlight body 1, a heat sink 2, and a connecting base 3. The heat sink 2 is fitted over the spotlight body 1, using its outer grid-like heat dissipation fins to dissipate the heat generated by the spotlight body 1 during operation to the surrounding environment, ensuring the normal operating temperature of the spotlight body 1. The bottom end of the heat sink 2 is magnetically attached to the connecting base 3, while the bottom end of the connecting base 3 abuts against the surface of the spotlight body 1. A limiting post 4 passes through the auxiliary ring 5 and is then threaded to the side wall of the connecting base 3, thus fixing the auxiliary ring 5 to the connecting base 3. The seal between the limiting post 4 and the auxiliary ring 5 prevents dust, moisture, etc., from entering the connection area and affecting the downlight performance. Four reflector segments 7 are installed at the bottom of the auxiliary ring 5, and all four reflector segments 7 are designed with arc-shaped joints. The four reflector segments 7 are assembled together to form a lampshade structure. The magnetic plates 9 on the side walls of adjacent reflector segments 7 attract each other, making the four reflector segments 7 tightly spliced ​​together to form a complete reflection space. The two magnetic plates 8 at the top of each reflector segment 7 attract the corresponding magnetic plates 6 at the bottom of the auxiliary ring 5, thereby fixing the reflector segment 7 to the auxiliary ring 5. The positioning bolt 10 passes through the auxiliary ring 5 and its bottom end connects to the groove on the surface of the reflector segment 7, further strengthening the connection stability between the reflector segment 7 and the auxiliary ring 5. When the spotlight body 1 emits light, the light shines on the inner wall of the reflector segment 7. Since the inner wall is coated with a reflective coating 11, it has good reflective performance. The light is reflected and converged, changing the direction of light propagation, thereby improving the utilization rate of light and the lighting effect, realizing the normal lighting function of the downlight, and increasing the overall practicality.

[0042] 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.
