[0033] In the following text, only some exemplary embodiments are briefly described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are considered to be exemplary in nature rather than restrictive.

[0034] Refer to Figures 1-4 , which shows a waterproof lamp of a preferred embodiment of the present utility model, including:

[0035] Base 1;

[0036] Circuit board 2, the circuit board 2 is disposed on the base 1 to be supported by the base 1; wherein, a light source is installed on the circuit board 2.

[0037] Lens 3, the lens 3 and the base 1 enclose a receiving cavity 4, the receiving cavity 4 houses the circuit board 2, and the lens 3 and the base 1 are connected together by ultrasonic welding to seal the receiving cavity 4.

[0038] For the waterproof lamp of the present utility model, the base 1 and the lens 3 are fixed together by ultrasonic welding, so that the receiving cavity 4 is sealed, and the waterproof effect is better, thereby isolating the circuit board 2 placed in the receiving cavity 4 from the outside world, so that the circuit board 2 will not be soaked by water. In the prior art, the method of pouring glue into the plastic shell not only makes the manufacturing process of the waterproof lamp cumbersome, but also easily generates bubbles and impurities during the manufacturing process. However, the waterproof lamp of the present application adopts the ultrasonic welding process, which not only simplifies its manufacturing process, but also avoids the generation of bubbles and impurities during the manufacturing process because there is no need for the glue pouring process.

[0039] In one embodiment, the base 1 is provided with an annular groove 14, the annular groove 14 surrounds the periphery of the receiving cavity 4, and the bottom of the lens 3 is embedded in the annular groove 14. In this way, by embedding the bottom of the lens 3 in the annular groove 14, not only the connection stability between the base 1 and the lens 3 is improved, but also ultrasonic welding can be directly performed at the connection between the annular groove 14 and the lens 3 to achieve further waterproofing by means of the shape of the annular groove 14.

[0040] In one embodiment, the waterproof lamp further includes a wire 5. A part of the wire 5 penetrates into the accommodation cavity 4 and is electrically connected to the circuit board 2. The wire 5 is fixed to the base 1 and / or the lens 3 by injection molding to form an injection molding structure 11 between the wire 5 and the base 1 and / or the lens 3. The injection molding structure 11 seals the gap between the wire 5 and the base 1 and / or the lens 3. That is to say, the wire 5 can be fixed to the base 1 by injection molding, or the wire 5 can be fixed to the lens 3 by injection molding, or the wire 5 can be fixed to both the base 1 and the lens 3 by injection molding. No matter how the wire 5 is fixed to the base 1 and / or the lens 3 by injection molding, it is to make the formed injection molding structure 11 seal the gap between the wire 5 and the base 1, and / or seal the gap between the wire 5 and the lens 3, so as to prevent water from entering the accommodation cavity 4 along the gap and soaking the circuit board 2. In other embodiments, the wire 5 can also be fixed to the base 1 by a sealing ring, or fixed to the lens 3 by a sealing ring, or fixed to both the base 1 and the lens 3 by a sealing ring.

[0041] In other embodiments, a power supply module (such as a disposable battery or a rechargeable battery) can be installed in the accommodation cavity 4, that is, there is no need to install the wire 5 and require one end of the wire 5 to be outside the accommodation cavity 4 and the other end of the wire 5 to be inside the accommodation cavity 4 to connect the circuit board 2 with an external power source. Therefore, setting the wire 5 is only one of the embodiments.

[0042] In one embodiment, in order to reduce the process difficulty, the wire 5 is fixed to the base 1 by injection molding, and the lens 3 is provided with a first avoidance groove 33 which is adapted to the injection molding structure 11. With such a setting, the wire 5 is fixed on the base 1, that is, it is allowed to first injection mold the wire 5 and the base 1 together, and then assemble them with the lens 3, without injection molding the wire 5, the base 1 and the lens 3 together, thus reducing the process difficulty. In addition, the lens 3 is a light-transmitting structure, and the injection molding structure 11 does not need to be made of a light-transmitting material, so it is more suitable to injection mold the wire 5 on the base 1. Moreover, by providing the first avoidance groove 33 at the bottom of the lens 3 to avoid the injection molding structure 11, the connection between the lens 3 and the base 1 is more fitting, and it is also more convenient to complete the ultrasonic welding work between the first avoidance groove 33 and the injection molding structure 11.

[0043] In one embodiment, there are two injection molding structures 11, which are relatively arranged on both sides of the base 1 (preferably on the opposite sides, so that the wire 5 does not need to be bent). There are two first avoidance grooves 33, and the two first avoidance grooves 33 are respectively connected to the two injection molding structures 11 in a one-to-one correspondence. The wire 5 sequentially passes through one injection molding structure 11, the accommodation cavity 4, and the other injection molding structure 11. In this way, the wires 5 of multiple waterproof lamps can be connected in series with each other and used as a bus, and the circuit boards 2 of each waterproof lamp are respectively connected to the wire 5 through branch lines. Among them, the wire 5 includes a live wire and a neutral wire, and can also include a ground wire at the same time; the branch lines also correspondingly include another live wire and a neutral wire, and can also include another ground wire at the same time; in this way, the wire 5 can connect multiple waterproof lamps in parallel at the same time.

[0044] In other embodiments, there is only one injection molding structure 11, and there is also only one first avoidance groove 33. At this time, the wire 5 belongs to one waterproof lamp, that is, one end of the wire 5 penetrates into the accommodation cavity 4 and is electrically connected to the circuit board 2, and the other end of the wire 5 is located outside the accommodation cavity 4 and connected to the power supply.

[0045] In one embodiment, based on the wire 5 being used as a bus, when using a branch line to connect the circuit board 2 and the bus, an operating space is required. Therefore, more preferably, the wire 5 is attached to the base 1, and the base 1 is provided with an installation part 12, and the circuit board 2 is arranged on the installation part 12, so that the circuit board 2 and the wire 5 are arranged at intervals to form the operating space, so as to facilitate the installation of the branch line. Moreover, after the wire 5 is attached to the base 1, not only is the structure compact, but there is no shaking phenomenon.

[0046] In one embodiment, the installation part 12 includes multiple support columns 121, and the multiple support columns 121 are arranged at intervals, and the circuit board 2 is lapped on the upper part of the support columns 121; in this way, the columnar installation part 12 makes the installation part 12 occupy less space in the accommodation cavity 4, so as to facilitate retaining the spacious space structure of the accommodation cavity 4, so as to facilitate the installation of each spare part.

[0047] In one embodiment, the support column 121 includes a first section 1211 and a second section 1212. The first section 1211 is connected to the base 1, and the first section 1211 and the second section 1212 are sequentially connected along the length direction of the support column 121. The circuit board 2 passes through the second section 1212 and is lapped on the first section 1211. In this way, after the circuit board 2 is lapped on the first section 1211, it is in a suspended state, so as to keep a certain distance from the wire 5 to stably maintain the operating space. Among them, both the first section 1211 and the second section 1212 can be set as a cylinder or a cuboid, the cross-sectional dimension of the first section 1211 is larger than that of the second section 1212, and the first section 1211 and the second section 1212 are coaxially arranged.

[0048] In other embodiments, the axes of the first section 1211 and the second section 1212 may not be coaxial. Moreover, the first section 1211 may be a cuboid or a cylinder, and the second section 1212 may be a cylinder or a cuboid, etc., as long as the condition that the first section 1211 supports the circuit board 2 and the second section 1212 penetrates through the circuit board 2 is satisfied.

[0049] In one embodiment, the injection molding structure 11 is provided with threaded holes 111, the circuit board 2 is connected with screws 6, and the screws 6 are connected with the threaded holes 111 to clamp the circuit board 2 on the mounting portion 12. In this way, the circuit board 2 is fixed on the mounting portion 12 by the screws 6 to prevent the circuit board 2 from falling off. In other embodiments, the circuit board 2 is fixed on the mounting portion 12 by an adhesive method or a snap method.

[0050] In one embodiment, there are a plurality of threaded holes 111 and screws 6, and the threaded holes 111 are connected to the corresponding screws 6 one by one to clamp the circuit board 2 more firmly on the mounting portion 12.

[0051] In one embodiment, one end of the screw 6 is electrically connected to the circuit board 2, and the other end of the screw 6 is electrically connected to the wire 5. In this way, the screw 6 not only serves to fix the circuit board 2 on the mounting portion 12, but also functions as the branch line, that is, the circuit board 2 and the wire 5 are electrically connected through the screw 6. Based on the fact that there are a plurality of screws 6, one screw 6 is connected to the live wire of the wire 5, another screw 6 is connected to the neutral wire of the wire 5, and another screw 6 is connected to the ground wire of the wire 5.

[0052] In one embodiment, the threaded hole 111 is a through hole. Based on the fact that the screw 6 penetrates through the threaded hole 111, that is, the screw 6 axially presses the wire 5. In other embodiments, even if the threaded hole 111 is a blind hole, after the screw 6 is connected to the threaded hole 111, the side wall of the end of the screw 6 can also be connected to the wire 5. That is to say, the connection part between the screw 6 and the wire 5 is not necessarily the end face of the end of the screw 6. However, it is more reliable to use the end face of the end of the screw 6 to contact and press the wire 5, because the screw 6 has an axial pressing force on the wire 5 after being tightened, which can ensure good contact between the two.

[0053] In one embodiment, the lens 3 is provided with an enclosing portion 31 and a light-transmitting portion 32. The enclosing portion 31 is arranged around the light-transmitting portion 32, and the bottom of the enclosing portion 31 is connected to the base 1 by an ultrasonic welding method. The light-transmitting portion 32 is used for the light of the light source 21 on the circuit board 2 to pass through. Among them, the light-transmitting portion 32 has a bowl-shaped structure. The enclosing portion 31 and the light-transmitting portion 32 are injection-molded together or connected together by a secondary injection molding process. The enclosing portion 31 can be made of a light-transmitting material or a non-light-transmitting material.

[0054] In one embodiment, the waterproof lamp further includes an outer cover 7. The outer cover 7 is connected to the base 1, surrounds the periphery of the enclosing portion 31, and is provided with a light-transmitting hole 71. The light-transmitting hole 71 penetrates through the outer cover 7 both vertically and horizontally, cooperates with the light-transmitting portion 32, and the hole wall of the light-transmitting hole 71 is closely attached to the outer wall of the light-transmitting portion 32 to prevent water from entering the outer cover 7 through the light-transmitting hole 71. In this way, the outer cover 7 not only plays a role in protecting the enclosing portion 31, but also plays a role in waterproofing.

[0055] In one implementation, the bottom of the outer cover 7 is snapped onto the card slot 13 of the base 1 to facilitate the quick installation of the outer cover 7 on the base 1.

[0056] In one embodiment, the outer cover 7 is provided with a second avoidance groove 72 for avoiding the wire 5 to allow the outer cover 7 to be closely connected to the base 1 as well; and there are two second avoidance grooves 72, which are respectively arranged on both sides of the outer cover 7.
