Description

Technical Field

[0001] This utility model relates to a lighting device, and more particularly to a spotlight. Background Technology

[0002] A spotlight is a type of focused lighting fixture that concentrates light onto a specific area. During installation and use, the beam angle can be adjusted as needed. To achieve this adjustment, the spotlight's lampshade is typically secured with screws or pins. The beam angle is adjusted by rotating the lampshade. However, this type of lampshade is cumbersome to install, requiring pre-positioning the lampshade against the spotlight before screwing in the screws or pins for connection and positioning. This assembly process is tedious and hinders overall efficiency. Therefore, there is a pressing need for a spotlight that is easier to assemble. Utility Model Content

[0003] The purpose of this utility model is to provide a spotlight to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] A spotlight includes: a lamp housing with a connecting buckle inside, the connecting buckle protruding downward from the lamp housing, the portion of the connecting buckle protruding from the lamp housing having a connecting hole, and a notch communicating with the connecting hole on the bottom side of the connecting buckle; a light source assembly disposed inside the lamp housing, the light source assembly emitting light downward; and a light emitter cover with a connector on its inner side, the connector being able to engage with the connecting hole through the notch, and the connector being able to rotate within the connecting hole.

[0006] This technical solution has at least the following beneficial effects: When assembling the lamp housing and the light emitter cover, since the connecting part protrudes downward from the lamp housing, the connecting buckle is directly inserted into the light emitter cover, and the connecting piece is aligned with the notch on the bottom side of the connecting buckle. An external force is applied to the connecting buckle and the connecting piece to bring them closer together, causing the connecting piece to pass over the notch and enter the connecting hole. At this time, the connecting piece is confined within the connecting hole. The relative positioning of the two is achieved by the friction between the connecting piece and the connecting buckle located inside the connecting hole. The light source component inside the lamp housing emits light to the light emitter cover located below. After the light emitter cover focuses the light, it illuminates the outside. When it is necessary to adjust the light emission angle, force can be directly applied to the light emitter cover, causing the connecting piece to rotate relative to the light emitter cover within the connecting hole. By adjusting the angle of the light emitter cover, the light emission angle is changed. In this way, the lamp housing and the light emitter cover can be quickly assembled through the cooperation of the connecting buckle and the connecting piece, and the rotation angle adjustment function of the light emitter cover can be realized. In addition, since the use of bolts, pins and other connecting components is reduced, it is beneficial to reduce production costs and improve production efficiency.

[0007] As a further improvement to the above technical solution, the connector includes two arc-shaped pieces connected to the inner side of the light-emitting cover. The two arc-shaped pieces are spaced apart circumferentially along the light-emitting cover, and their arc-shaped openings face each other. When the two arc-shaped pieces are pressed into the notch by external force, due to the space between them, they can elastically shift towards each other, thus entering the connecting hole at the notch. This makes it easier to snap into the connecting hole for positioning. At this time, the arc-shaped outer walls of the two arc-shaped pieces abut against the inner wall of the connecting hole, which can better fit with the connecting hole and increase the frictional positioning effect between them.

[0008] As a further improvement to the above technical solution, a limiting frame is connected to the inner side of the light-emitting cover, and the two arc-shaped pieces extend to the inner side of the limiting frame. A first opening is provided on the outer side of the light-emitting cover, and the bottoms of the two arc-shaped pieces extend into the first opening. When the connecting buckle is inserted into the light-emitting cover, the connecting buckle is inserted into the limiting frame, causing the two arc-shaped pieces to pass through the notch and enter the connecting hole. Since one end of the two arc-shaped pieces extends to the inner side of the limiting frame, the limiting frame can provide stable support for the ends of the two arc-shaped pieces, enhancing the structural stability of the two arc-shaped pieces. Furthermore, the bottoms of the two arc-shaped pieces extending into the first opening can ensure that the two arc-shaped pieces have good elastic displacement capability when compressed.

[0009] As a further improvement to the above technical solution, the light-emitting cover includes a face ring and a middle ring. The middle ring forms a light-emitting channel, and an annular surrounding plate is connected to the top side of the middle ring. The annular surrounding plate and the middle ring are detachably connected, and the connector is connected to the inner side of the annular surrounding plate. The face ring serves as an outer decorative surface and is used to connect with the external structure and protect the internal structure. Different face rings can be disassembled and replaced according to usage needs. After the face ring is installed on the outside of the middle ring, the two can rotate relative to each other for adjustment, improving the flexibility and convenience of use. The middle ring forms a light-emitting channel for emitting light. The light source assembly shines downward through the light-emitting channel and then outward. An annular surrounding plate for structural connection and support is connected to the top side of the middle ring. At this time, the connector is connected to the inner side of the annular surrounding plate. When the lamp housing and the light-emitting cover are assembled together, the connecting buckle extends into the annular surrounding plate and connects with the connector located on the inner side.

[0010] As a further improvement to the above technical solution, multiple spring pieces are arranged around the outer side of the annular surrounding plate, and the multiple spring pieces are connected to connecting posts. An annular groove is provided on the inner side of the face ring, and the multiple connecting posts extend into the multiple annular grooves respectively. When connecting the annular surrounding plate and the middle ring, the face ring is directly fitted onto the outer side of the middle ring. At this time, the connecting posts on the multiple spring pieces abut against the inner side of the face ring. After being subjected to the inward squeezing force of the face ring on the connecting posts, the multiple spring pieces undergo elastic deformation to avoid the connecting posts. When the face ring is fitted into place on the outer side of the middle ring, the multiple spring pieces elastically return to their original position, driving the multiple connecting posts into the annular groove, thereby restricting the direct separation of the face ring and the middle ring. At this time, the face ring can rotate relative to the middle ring, which facilitates the adjustment of the face ring's position during installation and improves the flexibility of use. When it is necessary to replace different face rings, it is only necessary to apply an external force to separate the face ring from the middle ring, causing the multiple spring pieces to elastically deform towards the center of the annular surrounding plate, thereby causing the multiple connecting posts to exit the annular groove.

[0011] As a further improvement to the above technical solution, the outer side of the annular enclosure is provided with multiple second openings, and multiple spring pieces are respectively connected to one side of the annular enclosure located at the multiple second openings. The multiple spring pieces are respectively located in the multiple second openings, and the second openings provide space for the elastic deformation of the spring pieces to move and avoid pressure. When the connecting column is subjected to the squeezing force from the inner side of the face ring, the spring pieces can elastically deform into the second openings and avoid pressure, thereby improving the stability of assembling the face ring and the middle ring together.

[0012] As a further improvement to the above technical solution, an anti-rotation rib is formed on the outer side of the middle ring, and an anti-rotation protrusion is formed on the inner side of the face ring. When the face ring rotates relative to the middle ring, the anti-rotation protrusion can abut against the anti-rotation rib. When the face ring rotates relative to the middle ring, the anti-rotation protrusion on the inner side of the face ring will abut against the anti-rotation rib on the outer side of the middle ring, which can restrict the relative rotation between the face ring and the middle ring. This can prevent the middle ring from rotating 360 degrees relative to the face ring, and help prevent the wires connected to the lamp housing from being excessively wound.

[0013] As a further improvement to the above technical solution, a heat sink is integrally formed inside the lamp housing, and the light source assembly is disposed on the bottom side of the heat sink. The heat sink can be injection molded into the lamp housing, which can enhance the tightness of the connection between the heat sink and the lamp housing, improve the heat dissipation effect of the heat sink through the lamp housing, and achieve the effect of strengthening insulation.

[0014] As a further improvement to the above technical solution, the light source assembly includes a light source plate and a lens. The light source plate is connected to the bottom side of the heat sink. A mounting frame is connected inside the lamp housing below the heat sink, and the lens is connected within the mounting frame. A connecting buckle is formed on the bottom side of the mounting frame. The light source plate, connected to the bottom side of the heat sink, directly conducts the heat generated during its operation to the heat sink, and then the heat sink evenly conducts it to the outer wall of the lamp housing, improving the heat dissipation effect on the light source plate. The lens used for light transmission is fixed by the mounting frame, thus separating the lens from the light source plate and the heat sink. When the light source plate is working, the light it generates can be emitted downwards through the lens.

[0015] As a further improvement to the above technical solution, a mounting post is connected to the top side of the lamp housing, and the mounting post extends downward through the heat sink. A mounting sleeve is connected to the top side of the mounting frame, and the top of the mounting sleeve is fitted onto the outer side of the bottom of the mounting post. When the mounting frame is installed inside the lamp housing, the mounting sleeve on the top side of the mounting frame and the mounting post on the top side of the lamp housing cooperate with each other, allowing the mounting frame to be quickly aligned and connected inside the lamp housing, thus improving the convenience of installing and fixing the mounting frame.

[0025] Reference Figure 1 and Figure 2A spotlight includes a lamp housing 100, a light source assembly, and a light emitter cover 200. The lamp housing 100 has a connecting buckle 110 inside, which protrudes downwards from the lamp housing 100. The portion of the connecting buckle 110 protruding from the lamp housing 100 has a connecting hole 111, and the bottom side of the connecting buckle 110 has a notch 112 communicating with the connecting hole 111. The light source assembly is disposed within the lamp housing 100 and emits light downwards. The light emitter cover 200 has a connector inside, which can be engaged with the connecting hole 111 through the notch 112 and can rotate within the connecting hole 111.

[0026] As described above, when assembling the lamp housing 100 and the light emitter cover 200, since the connecting part protrudes downward from the lamp housing 100, the connecting buckle 110 is directly inserted into the light emitter cover 200, and the connector is aligned with the notch 112 on the bottom side of the connecting buckle 110. An external force is applied to the connecting buckle 110 and the connector to bring them closer together, causing the connector to pass through the notch 112 and enter the connecting hole 111. At this time, the connector is confined within the connecting hole 111. The relative positioning of the connector and the connecting buckle 110 is achieved by the friction between them located inside the connecting hole 111. The light source assembly inside the lamp housing 100 moves towards the light emitter cover 200. The lower light emitter 200 emits light, which is then focused and directed outwards for illumination. When the light emission angle needs to be adjusted, force can be applied directly to the light emitter 200, causing the connector to rotate relative to the light emitter 200 within the connecting hole 111. By adjusting the angle of the light emitter 200, the light emission angle can be changed. Thus, the lamp housing 100 and the light emitter 200 can be quickly assembled through the cooperation of the connecting buckle 110 and the connector, and the rotation angle adjustment function of the light emitter 200 can be realized. In addition, the reduction of the use of bolts, pins and other connecting components helps to reduce production costs and improve production efficiency.

[0027] The connector can be a solid columnar structure. When the connector needs to pass through the notch 112 and enter the connecting hole 111, it needs to rely on the elastic deformation of the connecting buckle 110 at the notch 112 to avoid the connector. In order to make it easier for the connector to enter the connecting hole 111, the connector can also be set as a hollow structure. In this embodiment, the connector includes two arc-shaped pieces 210 connected to the inner side of the light-emitting cover 200. The two arc-shaped pieces 210 are arranged at intervals along the circumference of the light-emitting cover 200, and the arc-shaped openings of the two arc-shaped pieces 210 face each other. When the two arc-shaped pieces 210 are squeezed into the notch 112 by external force, due to the space between the two arc-shaped pieces 210, the two arc-shaped pieces 210 can elastically shift towards each other, thereby entering the connecting hole 111 at the notch 112. This makes it easier to be inserted into the connecting hole 111 for positioning. At this time, the arc-shaped outer walls of the two arc-shaped pieces 210 abut against the inner wall of the connecting hole 111, which can better fit with the connecting hole 111 and increase the frictional positioning effect between the two.

[0028] In practical applications, there can be multiple connecting buckles 110, such as two. In this case, the two connecting buckles 110 are respectively set on both sides of the lamp housing 100, and there are also two connecting parts. The two connecting parts can be connected with the two connecting buckles 110 respectively, thereby improving the stability of the connection between the lamp housing 100 and the light emitter cover 200.

[0029] One end of each of the two arc-shaped pieces 210 is connected to the inside of the light-emitting mask 200. When the other ends of the two arc-shaped pieces 210 are directly suspended inside the light-emitting mask 200, the structural stability of the two arc-shaped pieces 210 is low. Therefore, a structure to enhance the stability of the two arc-shaped pieces 210 is provided inside the light-emitting mask 200. Specifically, a limiting frame 220 is connected to the inside of the light-emitting mask 200, and the two arc-shaped pieces 210 extend to the inside of the limiting frame 220. A first opening 230 is provided on the outside of the light-emitting mask 200, and the bottoms of the two arc-shaped pieces 210 extend into the first opening 230. In a further embodiment, when the light-emitting mask 200 includes a face ring 240 and a middle ring 250, two connecting pieces are connected to the inside of the annular surrounding plate 260. Similarly, the limiting frame 220 is also connected to the inside of the annular surrounding plate 260. When the connecting buckle 110 extends into the light cover 200, the connecting buckle 110 is inserted into the limiting frame 220, and the two arc-shaped pieces 210 pass through the notch 112 and enter into the connecting hole 111. Since one end of the two arc-shaped pieces 210 extends into the inside of the limiting frame 220, the limiting frame 220 can provide stable support for the ends of the two arc-shaped pieces 210, thereby enhancing the structural stability of the two arc-shaped pieces 210. Furthermore, the bottom of the two arc-shaped pieces 210 extends into the first hole 230, which can ensure that the two arc-shaped pieces 210 have good elastic displacement ability when they are squeezed.

[0030] To facilitate the production and forming of the internal structure and the optional assembly of the light emitter 200 as a whole, in this embodiment, the light emitter 200 includes a face ring 240 and a middle ring 250. The middle ring 250 surrounds and forms a light emission channel 251. An annular surrounding plate 260 is connected to the top side of the middle portion of the middle ring 250. The annular surrounding plate 260 is an annular structural component that extends around the center of the middle ring 250 from the top side of the middle portion of the middle ring 250. The annular surrounding plate 260 and the middle ring 250 are detachably connected, and the connecting member is connected to the inner side of the annular surrounding plate 260. The face ring 240 serves as an external decorative surface and is used to connect with the external structure and protect the internal structure. Different face rings 240 can be disassembled and replaced as needed. After the face ring 240 is installed on the outside of the middle ring 250, the two can rotate relative to each other for adjustment, improving the flexibility and convenience of use. The middle ring 250 forms a light emission channel 251 for emitting light. The light source assembly shines downward through the light emission channel 251 and then outward. A ring-shaped enclosure 260 for structural connection and support is connected to the top side of the middle ring 250. At this time, the connector is connected to the inside of the ring-shaped enclosure 260. When the lamp housing 100 and the light emission cover 200 are assembled together, the connecting buckle 110 extends into the ring-shaped enclosure 260 and connects with the connector located on the inside.

[0031] The annular surrounding plate 260 and the middle ring 250 can be connected by a snap-fit ​​or by screws. In this embodiment, after connecting the annular surrounding plate 260 and the middle ring 250, the face ring 240 and the middle ring 250 can also rotate relative to each other. Specifically, a plurality of spring pieces 261 are arranged around the outer side of the annular surrounding plate 260, and the plurality of spring pieces 261 are connected to connecting posts 262. An annular groove 241 is provided on the inner side of the face ring 240, and the plurality of connecting posts 262 extend into the plurality of annular grooves 241 respectively. In practical applications, there can be a plurality of spring pieces 261, such as three to six, in which case the plurality of spring pieces 261 are evenly arranged around the annular surrounding plate 260. When connecting the annular surrounding plate 260 and the middle ring 250, the face ring 240 is directly fitted onto the outside of the middle ring 250. At this time, the connecting posts 262 on the multiple spring pieces 261 abut against the inside of the face ring 240. After being subjected to the inward pressing force of the face ring 240 on the connecting posts 262, the multiple spring pieces 261 undergo elastic deformation to avoid the connecting posts 262. When the face ring 240 is fitted onto the outside of the middle ring 250, the multiple spring pieces 261 elastically recover, driving the multiple connecting posts 262 into the annular surrounding plate 260. The groove 241 restricts the direct separation of the face ring 240 and the middle ring 250. At this time, the face ring 240 can rotate relative to the middle ring 250, which facilitates the adjustment of the position of the face ring 240 during installation and improves the flexibility of use. When it is necessary to replace different face rings 240, it is only necessary to apply an external force to separate the face ring 240 from the middle ring 250, so that multiple spring pieces 261 elastically deform towards the center of the annular surrounding plate 260, thereby causing multiple connecting posts 262 to exit the annular groove 241.

[0032] In the above embodiment, the spring piece 261 can be directly connected to the outside of the annular surrounding plate 260. To ensure that the spring piece 261 has space for elastic deformation, the spring piece 261 can arch away from the annular surrounding plate 260 or extend outward at an angle. In order to make the overall structure more compact, in this embodiment, a plurality of second openings 263 are provided on the outside of the annular surrounding plate 260, and the plurality of spring pieces 261 are respectively connected to one side of the annular surrounding plate 260 located in the plurality of second openings 263. The plurality of spring pieces 261 are respectively located in the plurality of second openings 263. The second openings 263 can provide space for the elastic deformation of the spring piece 261. When the connecting post 262 is subjected to the squeezing force of the inner side of the face ring 240, the spring piece 261 can elastically deform into the second opening 263 and avoid it, thereby improving the stability of assembling the face ring 240 and the middle ring 250 together.

[0033] When the face ring 240 and the middle ring 250 rotate relative to each other, if the rotation of the middle ring 250 is too large, the wires connected to the middle ring 250 will become entangled with the face ring 240. Therefore, in this embodiment, an anti-rotation rib is formed on the outer side of the middle ring 250, and an anti-rotation protrusion 242 is formed on the inner side of the face ring 240. When the face ring 240 rotates relative to the middle ring 250, the anti-rotation protrusion 242 can abut against the anti-rotation rib. When the face ring 240 rotates relative to the middle ring 250, the anti-rotation protrusion 242 on the inner side of the face ring 240 will abut against the anti-rotation rib on the outer side of the middle ring 250. At this time, the relative rotation of the face ring 240 and the middle ring 250 can be restricted. This can prevent the middle ring 250 from rotating 360 degrees relative to the face ring 240, which helps to prevent the wires connected to the lamp housing 100 from being excessively wound.

[0034] The anti-rotation protrusion 242 on the inner side of the face ring 240 can be a protrusion structure formed directly on the inner side of the face ring 240 during the production of the face ring 240, or it can be a protrusion structure formed inside the face ring 240 by making concave points on the outer side of the face ring 240 after the face ring 240 is produced.

[0035] To improve the heat dissipation effect inside the lamp housing 100, in this embodiment, a heat sink 120 is integrally formed inside the lamp housing 100, and the light source assembly is disposed on the bottom side of the heat sink 120. In practical applications, the lamp housing 100 can be made of plastic, while the heat sink 120 can be made of metal, which better controls product costs while ensuring structural strength and heat dissipation effect. The heat sink 120 can be injection molded into the lamp housing 100, which can enhance the tightness of the connection between the heat sink 120 and the lamp housing 100, improve the heat dissipation effect of the heat sink 120 through the lamp housing 100, and achieve a stronger insulation effect.

[0036] The light source component is mainly used to emit light. In this embodiment, such as Figure 3 As shown, the light source assembly includes a light source plate 310 and a lens 320. The light source plate 310 is connected to the bottom side of the heat sink 120. A mounting frame 130 is connected inside the lamp housing 100 below the heat sink 120. The lens 320 is connected inside the mounting frame 130. The connecting buckle 110 can be a structural component directly installed inside the lamp housing 100. In this embodiment, the connecting buckle 110 is formed on the bottom side of the mounting frame 130. The light source plate 310 is connected to the bottom side of the heat sink 120. The heat generated when it is working is directly conducted to the heat sink 120, and then evenly conducted to the outer wall of the lamp housing 100, improving the heat dissipation effect of the light source plate 310. The lens 320, which is used for light transmission, is fixed by the mounting frame 130, so that the lens 320 is separated from the light source plate 310 and the heat sink 120. When the light source plate 310 is working, the light it generates can be emitted downward through the lens 320.

[0037] In some embodiments, a mounting post 140 is connected to the top side of the lamp housing 100, and the mounting post 140 extends downward through the heat sink 120. A mounting sleeve 131 is connected to the top side of the mounting frame 130, and the top of the mounting sleeve 131 is fitted onto the outer side of the bottom of the mounting post 140. In practical applications, there can be multiple mounting posts 140 and multiple mounting sleeves 131, each corresponding to a different mounting post 140. When the mounting frame 130 is installed inside the lamp housing 100, the mounting sleeve 131 on the top side of the mounting frame 130 and the mounting post 140 on the top side of the lamp housing 100 cooperate with each other, allowing the mounting frame 130 to be quickly aligned and connected inside the lamp housing 100, thus improving the convenience of installing and fixing the mounting frame 130.
