[0002] Lighting devices are sometimes used in humid environments, such as being installed in water, outdoors, or near a water source. The front ring of the lighting device needs to be equipped with waterproof accessories to prevent water vapor from entering the interior of the lighting device. However, the structures of lighting devices (such as downlights or spotlights) are diverse, resulting in a corresponding variety of waterproof accessories. The design of waterproof accessories is complex and the cost is high. Utility Model Content
[0003] The inventor of the present application realizes that conventional waterproof accessories are rigidly mounted on lighting devices, and the shape and size of the waterproof accessories need to be precisely matched to the shape and size of the lighting device. Otherwise, the waterproof accessories are not tightly connected to the lighting device, and the waterproof accessories cannot provide waterproof protection for the lighting device, resulting in a wide variety of waterproof accessories, high manufacturing precision requirements, and high manufacturing costs. The purpose of the present utility model is to provide a waterproof accessory and a lighting device, aiming to solve the technical problem that the existing waterproof accessories are of various types and high costs.

At the same time, the central area of the waterproof accessories is a rigid area, which ensures that the light emission angle of the lighting device is stable and controllable, and avoids shaking of the emission angle due to flexible deformation of the central area of the waterproof accessories.
[0005] In a first aspect, the present application provides a waterproof accessory, the waterproof accessory comprising:
[0006] Rigid light-transmitting parts;
[0007] A flexible connecting ring has a through hole that passes through the flexible connecting ring along the thickness direction, the rigid light-transmitting member is fixedly positioned and sealed to the flexible connecting ring, the rigid light-transmitting member seals the through hole, the flexible connecting ring has a first mounting groove arranged around the through hole, and the first mounting groove is located on one side of the rigid light-transmitting member in the thickness direction.
[0008] In one of the embodiments, the flexible connecting ring is welded to the outer edge of the rigid light-transmitting component. The flexible connecting ring is used to melt part of the material in contact with the rigid light-transmitting component and re-solidify on the rigid light-transmitting component. The shape and size of the flexible connecting ring are adapted to the shape and size of the rigid light-transmitting component. The two are tightly combined to form a whole, which effectively prevents water vapor from penetrating into the interior of the waterproof accessory through the connection. The connection strength is not easily affected by changes in external temperature and humidity and long-term use, thereby improving the reliability and stability of the connection and having strong impact and vibration resistance.
[0009] In one of the embodiments, the flexible connecting ring is injection molded on the outer edge of the rigid light-transmitting component. The flexible connecting ring is injection molded on the outer edge of the rigid light-transmitting component, which can well match the shape and size of the rigid light-transmitting component, thereby preventing the two from being unable to be assembled or having a loose connection after assembly due to large size deviations due to separate manufacturing, thereby enhancing the air tightness of the connection between the flexible connecting ring and the rigid light-transmitting component and preventing water vapor from penetrating into the interior of the waterproof accessory through the connection.
[0010] In one of the embodiments, the flexible connecting ring is adhesively fixed to the outer edge of the rigid light-transmitting component, and glue fills any gap between the flexible connecting ring and the rigid light-transmitting component, thereby achieving a firm connection between the flexible connecting ring and the rigid light-transmitting component, enhancing the air tightness of the connection between the flexible connecting ring and the rigid light-transmitting component, and preventing water vapor from penetrating into the interior of the waterproof accessory through the connection.
[0011] In one embodiment, the projection of the first mounting groove and the rigid light-transmitting member in the thickness direction overlap. The first mounting groove is used to sleeve the front ring of the lighting device, that is, the projection of the front ring and the rigid light-transmitting member in the thickness direction overlap, the front ring and the rigid light-transmitting member respectively abut against the flexible connecting ring, and the two support each other, and the front ring limits the rigid light-transmitting member from rotating at an angle, further improving the position stability and position reliability of the rigid light-transmitting member, and further improving the light emission angle stability and reliability of the lighting device.
[0012] In one of the embodiments, the outer edge of the rigid light-transmitting component is fixedly embedded in the hole wall of the through hole, and the hole wall of the through hole wraps the outer edge of the rigid light-transmitting component, isolating the outer edge of the rigid light-transmitting component from the external environment, preventing water vapor from penetrating into the interior of the waterproof accessory along the outer edge surface of the rigid light-transmitting component, and further improving the waterproof performance of the lighting device.
[0013] In one embodiment, one of the rigid light-transmitting member and the flexible connecting ring is provided with a groove, and the other of the rigid light-transmitting member and the flexible connecting ring is provided with a protrusion, and the protrusion is embedded in the groove. In this way, the protrusion and the groove are embedded, which, on the one hand, increases the connection area between the rigid light-transmitting member and the flexible connecting ring, improves the connection strength between the rigid light-transmitting member and the flexible connecting ring, and on the other hand, limits the rotation of the rigid light-transmitting member relative to the flexible connecting ring in the thickness direction, and the two together enhance the position stability and position reliability of the rigid light-transmitting member.
[0014] In one embodiment, the shape of the protrusion matches the shape of the groove, and the notch width of the groove is smaller than the maximum width of the groove. In this way, the width of the protrusion embedded in the groove is larger than the notch width of the groove, and the groove is designed with a narrowing at the notch position, so that the protrusion is difficult to escape from the groove through the notch of the groove, thereby enhancing the friction and connection strength between the rigid light-transmitting member and the flexible connecting ring, increasing the difficulty of separating the rigid light-transmitting member and the flexible connecting ring along the radial direction of the through hole, and thus enhancing the position stability and position reliability of the rigid light-transmitting member.
[0015] In one of the embodiments, the rigid light-transmitting member is in the shape of a flat plate, which reduces the difficulty of processing the rigid light-transmitting member, helps to reduce the manufacturing cost of waterproof accessories, is applicable to the light emission requirements of various lighting devices, and has good versatility.
[0016] In one embodiment, the rigid light-transmitting member is in the shape of an arc surface, and the arc surface of the rigid light-transmitting member protrudes in the direction away from the first mounting groove. When the waterproof accessory is applied to a lighting device, the light board and the rigid light-transmitting plate of the lighting device are respectively located on both sides of the first mounting groove, and the rigid light-transmitting member with an arc surface can increase the distance between the light board and the light board, so that when the light board rotates to adjust the light output angle, the light board will not interfere with the rigid light-transmitting member. In addition, the arc surface of the rigid light-transmitting member makes the emitted light more dispersed and uniform in all directions on the one hand, and on the other hand, it is conducive to the water droplets on the outer surface of the waterproof accessory to fall along the arc surface, avoiding water vapor from gathering on the outer surface of the waterproof accessory.
[0017] In one embodiment, a waterproof rib is provided on the surface of the flexible connection ring, the waterproof rib is located on the side of the first mounting groove away from the rigid light-transmitting member, and the waterproof rib extends along the circumference of the through hole. The waterproof rib is protruding on the surface of the flexible connection ring, which can prevent water vapor from flowing horizontally along the surface of the flexible connection ring to the connection position between the flexible connection ring and the lighting device, prevent water vapor from approaching the interior of the lighting device, and improve the waterproof performance of the waterproof accessory and the lighting device.
[0018] In one of the embodiments, the waterproof rib is arranged around the through hole, thereby preventing water vapor from flowing to the connection position between the flexible connecting ring and the lighting device in all directions along the circumferential direction of 360°, further improving the waterproof performance.
[0019] In one embodiment, there are multiple waterproof ribs, and the multiple waterproof ribs are distributed at intervals along the radial direction of the flexible connecting ring to form multi-level waterproof protection, so that it is difficult for water vapor to pass through the multiple waterproof ribs and flow to the connection position between the flexible connecting ring and the lighting device.
[0020] In a second aspect, the present application provides a lighting device, comprising a lamp body and any one of the waterproof accessories described above, wherein the waterproof accessory is mounted on a front ring of the lamp body so that the front ring is embedded in the first mounting groove.

[0041] Embodiment 1
[0042] Combination Figure 4 and Figure 5 The waterproof accessory 20 of the present application includes a rigid light-transmitting member 21 and a flexible connecting ring 22. The flexible connecting ring 22 has a through hole 221 that passes through the flexible connecting ring 22 in the thickness direction. The rigid light-transmitting member 21 is fixedly and sealedly connected to the flexible connecting ring 22, and the rigid light-transmitting member 21 seals the through hole 221. The flexible connecting ring 22 has a first mounting groove 222 arranged around the through hole 221, and the first mounting groove 222 is located on one side of the rigid light-transmitting member 21 in the thickness direction.
[0043] Please also read Figure 1 and Figure 2The flexible connection ring 22 wraps the outer edge of the lighting device through the first installation groove 222 to isolate the outer edge of the lighting device from the external environment. The flexible connection ring 22 can adapt to lighting devices of different shapes and sizes through flexible deformation, thereby improving the versatility of the waterproof accessory 20, helping to reduce the number of types of waterproof accessories 20, reducing the manufacturing precision requirements of the waterproof accessories 20, and comprehensively reducing the manufacturing cost of the waterproof accessories 20. At the same time, the rigid light-transmitting component 21 is sealed and installed in a fixed position on the flexible connection ring 22, which is beneficial for the light of the lighting device to be emitted through the rigid light-transmitting component 21, and ensures that the light emission angle of the lighting device is stable and controllable, avoiding the shaking of the emission angle due to the flexible deformation of the central area of the waterproof accessory 20.
[0044] Specifically, the first mounting groove 222 is sleeved on the front ring 11 of the lighting device, so that the front ring 11 is embedded in the first mounting groove 222 .
[0045] In some embodiments, in combination Figure 3 and Figure 6 The slot width a of the first mounting slot 222 is smaller than the maximum width b of the first mounting slot 222. The first mounting slot 222 is designed with a narrowing at the slot position. The outer edge of the lighting device embedded in the first mounting slot 222 is difficult to escape from the first mounting slot 222 through the slot of the first mounting slot 222, thereby enhancing the friction and connection strength between the lighting device and the flexible connecting ring 22.
[0046] Specifically, combined Figure 3 The groove wall of the first installation groove 222 is provided with a step, so that the inner width b of the first installation groove 222 is greater than the groove width a of the first installation groove 222 .
[0047] Specifically, combined Figure 3 The end width of the outer edge of the front ring 11 is adapted to the maximum width b of the first mounting groove 222. The outer edge of the front ring 11 enters the interior of the first mounting groove 222 by squeezing the flexible connecting ring 22 and is clamped in the first mounting groove 222. It is difficult to detach from the first mounting groove 222 without external force.
[0048] In some embodiments, the first mounting groove 222 extends along the circumference of the through hole 221, increasing the length of the first mounting groove 222, thereby increasing the connection length and connection strength between the flexible connection ring 22 and the front ring 11. Specifically, the first mounting groove 222 is arranged around the through hole 221, and the notch of the first mounting groove 222 is connected to the through hole 221. The front ring 11 located in the first mounting groove 222 is limited by the groove wall of the first mounting groove 222 in the thickness direction, and is limited by the groove bottom of the first mounting groove 222 in the radial direction of the through hole 221, so that the position of the front ring 11 is stable.
[0049] In one embodiment, in combination Figure 6The flexible connecting ring 22 is welded to the outer edge of the rigid light-transmitting member 21. The flexible connecting ring 22 is used to melt part of the material in contact with the rigid light-transmitting member 21 and re-solidify on the rigid light-transmitting member 21. The shape and size of the flexible connecting ring 22 are adapted to the shape and size of the rigid light-transmitting member 21. The two are tightly combined to form a whole, which effectively prevents water vapor from penetrating into the interior of the waterproof accessory 20 through the connection, and the connection strength is not easily affected by changes in external temperature and humidity and long-term use. The reliability and stability of the connection are improved, and it has strong impact and vibration resistance.
[0050] In another embodiment, in combination Figure 6 The flexible connecting ring 22 is injection molded on the outer edge of the rigid light-transmitting component 21. The flexible connecting ring 22 is injection molded on the outer edge of the rigid light-transmitting component 21, which can well match the shape and size of the rigid light-transmitting component 21, avoiding the two being unable to be assembled or the connection being loose after assembly due to large size deviation caused by separate manufacturing, thereby enhancing the air tightness of the connection between the flexible connecting ring 22 and the rigid light-transmitting component 21, and preventing water vapor from penetrating into the interior of the waterproof accessory 20 through the connection.
[0051] In another embodiment, in combination Figure 6 The flexible connecting ring 22 is bonded and fixed to the outer edge of the rigid light-transmitting member 21, and the glue fills the possible gap between the flexible connecting ring 22 and the rigid light-transmitting member 21, thereby achieving a firm connection between the flexible connecting ring 22 and the rigid light-transmitting member 21, enhancing the air tightness of the connection between the flexible connecting ring 22 and the rigid light-transmitting member 21, and preventing water vapor from penetrating into the interior of the waterproof accessory 20 through the connection.
[0052] In some embodiments, in combination Figure 6 The outer edge of the rigid light-transmitting member 21 is fixedly embedded in the hole wall of the through hole 221, and the hole wall of the through hole 221 wraps the outer edge of the rigid light-transmitting member 21, isolating the outer edge of the rigid light-transmitting member 21 from the external environment, preventing water vapor from penetrating into the interior of the waterproof accessory 20 along the outer edge surface of the rigid light-transmitting member 21, and further improving the waterproof performance of the lighting device.
[0053] Specifically, combined Figure 6 The hole wall of the through hole 221 has a second mounting groove 223, and the second mounting groove 223 is arranged around the through hole 221. The outer edge of the rigid light-transmitting member 21 is fixedly embedded in the second mounting groove 223. The second mounting groove 223 can be actively formed or passively formed. For example, the flexible connecting ring 22 is welded or injection molded to the outer edge of the rigid light-transmitting member 21, so that the flexible connecting ring 22 wraps the outer edge of the rigid light-transmitting member 21, and the flexible connecting ring 22 passively forms the second mounting groove 223 by avoiding the outer edge of the rigid light-transmitting member 21 from being concave. For another example, the hole wall of the through hole 221 actively forms the second mounting groove 223, and the outer edge of the rigid light-transmitting member 21 is then adhesively fixed in the second mounting groove 223.
[0054] In some embodiments, in combination Figure 3 , the projection of the first mounting groove 222 and the rigid light-transmitting member 21 in the thickness direction overlap. The first mounting groove 222 is used to sleeve the front ring 11 of the lighting device, that is, the projection of the front ring 11 and the rigid light-transmitting member 21 in the thickness direction overlap, the front ring 11 and the rigid light-transmitting member 21 respectively abut against the flexible connecting ring 22, and the two support each other. The front ring 11 limits the angular rotation of the rigid light-transmitting member 21, further improving the position stability and position reliability of the rigid light-transmitting member 21, and further improving the light emission angle stability and reliability of the lighting device.
[0055] Specifically, the projections of the first mounting groove 222 and the second mounting groove 223 in the thickness direction overlap, thereby ensuring that the projections of the front ring 11 and the rigid light-transmitting member 21 in the thickness direction overlap.
[0056] In some embodiments, in combination Figure 7 , Figure 8 and Fig.11 , one of the rigid light-transmitting member 21 and the flexible connecting ring 22 is provided with a groove 211, and the other of the rigid light-transmitting member 21 and the flexible connecting ring 22 is provided with a convex block 224, and the convex block 224 is embedded in the groove 211. In this way, the convex block 224 and the groove 211 are embedded in each other, which, on the one hand, increases the connection area between the rigid light-transmitting member 21 and the flexible connecting ring 22, and improves the connection strength between the rigid light-transmitting member 21 and the flexible connecting ring 22, and on the other hand, limits the rotation of the rigid light-transmitting member 21 relative to the flexible connecting ring 22 around the thickness direction, and the two together enhance the position stability and position reliability of the rigid light-transmitting member 21.
[0057] Specifically, combined Figure 7 The protrusion 224 or the groove 211 of the flexible connecting ring 22 can be formed actively or passively, which is not limited here. For example, when the outer edge of the rigid light-transmitting member 21 is provided with a protrusion 224, the flexible connecting ring 22 is welded or injection-molded to the outer edge of the rigid light-transmitting member 21, and the position of the flexible connecting ring 22 corresponding to the protrusion 224 of the rigid light-transmitting member 21 is passively formed to wrap the protrusion 224; when the outer edge of the rigid light-transmitting member 21 is provided with a groove 211, the flexible connecting ring 22 is welded or injection-molded to the outer edge of the rigid light-transmitting member 21, and the position of the flexible connecting ring 22 corresponding to the groove 211 of the rigid light-transmitting member 21 is passively formed to embed the protrusion 224 in the groove 211. For another example, the flexible connecting ring 22 actively forms the protrusion 224 or the groove 211, and the protrusion 224 and the groove 211 are embedded and matched with each other through extrusion. Optionally, the protrusion 224 and the groove wall of the groove 211 can be glued to further enhance the connection strength.
[0058] Specifically, combined Figure 8 and Fig.11, the outer edge of the rigid light-transmitting member 21 is provided with a groove 211, and the flexible connecting ring 22 is provided with a protrusion 224. It can be understood that in other embodiments, the outer edge of the rigid light-transmitting member 21 is provided with a protrusion 224, and the flexible connecting ring 22 is provided with a groove 211, which is not limited here.
[0059] In one embodiment, in combination Figure 7 , Figure 8 and Fig.11 The shape of the protrusion 224 matches the shape of the groove 211, and the notch width c of the groove 211 is smaller than the maximum width d of the groove 211. In this way, the width of the protrusion 224 embedded in the groove 211 is larger than the notch width c, and the groove 211 is designed with a narrowing at the notch position, so that it is difficult for the protrusion 224 to escape from the groove 211 through the notch of the groove 211, thereby enhancing the friction and connection strength between the rigid light-transmitting member 21 and the flexible connecting ring 22, and increasing the difficulty of separating the rigid light-transmitting member 21 and the flexible connecting ring 22 along the radial direction of the through hole 221, thereby enhancing the position stability and position reliability of the rigid light-transmitting member 21.
[0060] In some embodiments, in combination Fig. 9 and Fig.10 The rigid light-transmitting member 21 is in the shape of a flat plate, which reduces the difficulty of processing the rigid light-transmitting member 21, helps to reduce the manufacturing cost of the waterproof accessory 20, is suitable for the light emission requirements of various lighting devices, and has good versatility.
[0061] In other embodiments, in combination Figure 4 and Figure 5 , the rigid light-transmitting member 21 is in the shape of an arc surface, and the arc surface of the rigid light-transmitting member 21 protrudes in the direction away from the first mounting groove 222. When the waterproof accessory 20 is applied to a lighting device, the light board and the rigid light-transmitting plate 21 of the lighting device are respectively located on both sides of the first mounting groove 222, and the rigid light-transmitting member 21 with an arc surface can increase the distance between the light board and the rigid light-transmitting member 21, so that when the light board rotates to adjust the light output angle, the light board will not interfere with the rigid light-transmitting member 21.
[0062] In addition, the curved surface of the rigid light-transmitting member 21 , on the one hand, makes the outgoing light more dispersed and uniform in all directions, and on the other hand, helps water droplets on the outer surface of the waterproof accessory 20 to fall along the curved surface of the rigid light-transmitting member 21 , thereby preventing water vapor from gathering on the outer surface of the waterproof accessory 20 .
[0063] In some embodiments, in combination Figure 1 and Figure 2The surface of the flexible connection ring 22 is provided with a waterproof rib 225, which is located on the side of the first mounting groove 222 away from the rigid light-transmitting member 21, and extends along the circumference of the through hole 221. The waterproof rib 225 is convexly arranged on the surface of the flexible connection ring 22, which can prevent water vapor from flowing horizontally along the surface of the flexible connection ring 22 to the connection position between the flexible connection ring 22 and the lighting device, prevent water vapor from approaching the interior of the lighting device, and improve the waterproof performance of the waterproof accessory 20 and the lighting device.
[0064] In one embodiment, in combination Figure 1 The waterproof rib 225 is arranged around the through hole 221, thereby preventing water vapor from flowing to the connection position between the flexible connecting ring 22 and the lighting device in all directions along the circumferential direction of 360°, further improving the waterproof performance.
[0065] In one embodiment, in combination Figure 2 There are multiple waterproof ribs 225, which are spaced apart radially along the flexible connecting ring 22 to form multi-level waterproof protection, making it difficult for water vapor to pass through the multiple waterproof ribs 225 and flow to the connection position between the flexible connecting ring 22 and the lighting device.
[0066] Embodiment 2
[0067] Combination Figure 1 and Figure 2 The present application provides a lighting device, which includes a lamp body 10 and any one of the waterproof accessories 20 in the first embodiment. The waterproof accessory 20 is sleeved on the front ring 11 of the lamp body 10, so that the front ring 11 is embedded in the first mounting groove 222, isolating the front ring 11 from the external environment, and the flexible connecting ring 22 can adapt to the front ring 11 of lighting devices of different shapes and sizes through flexible deformation, thereby improving the versatility of the waterproof accessory 20, helping to reduce the number of types of waterproof accessories 20, reducing the manufacturing precision requirements of the waterproof accessories 20, and comprehensively reducing the manufacturing cost of the waterproof accessories 20. At the same time, the rigid light-transmitting member 21 is fixedly installed in a sealed manner on the flexible connecting ring 22, which is conducive to the light of the lamp body 10 to be emitted through the rigid light-transmitting member 21, and ensures that the light emission angle of the lamp body 10 is stable and controllable, avoiding the shaking of the emission angle due to the flexible deformation of the central area of the waterproof accessory 20.
