[0034] A base 1, the base 1 having a mounting portion 11 and at least two first connection holes 12, wherein the at least two first connection holes 12 are arranged around the mounting portion 11;

[0035] A circuit board 2, the circuit board 2 is arranged on the mounting portion 11, and a light source 21 is arranged on the circuit board 2;

[0036] A lens 3, which is disposed on the base 1 and covers the circuit board 2. The lens 3 is used for allowing the light emitted by the light source 21 to pass through. The lens 3 is provided with at least two second connection holes 31;

[0037] At least two fasteners 4, each fastener 4 is connected to the first connecting hole 12 and the second connecting hole 31 which are aligned with each other in a one-to-one correspondence, so as to connect the base 1 and the lens 3 together;

[0038] The sealing member 5 is disposed around the mounting portion 11 , and the sealing member 5 is sandwiched between the base 1 and the lens 3 to seal the gap between the base 1 and the lens 3 .

[0039] The waterproof lamp of the utility model realizes that the circuit board 2 is installed on the base 1 by arranging the circuit board 2 on the mounting portion 11, and at the same time, the lens 3 is covered on the base 1 and covers the circuit board 2, so that the circuit board 2 is arranged in a space surrounded by the base 1 and the lens 3. Since the base 1 and the lens 3 are connected together by the fastener 4, the base 1 and the lens 3 can be reliably fixed together, and the structural reliability is high. At the same time, since the sealing member 5 is arranged around the mounting portion 11 and clamped between the base 1 and the lens 3, the sealing member 5 is subjected to the tensile force applied between the base 1 and the lens 3 by the fastener 4 and is squeezed by the base 1 and the lens 3, so that the bottom surface of the sealing member 5 is in close contact with the base 1, and the top surface of the sealing member 5 is in close contact with the lens 3, thereby realizing the gap between the base 1 and the lens 3 without sealing with sealant, replacing the connection method of the prior art that uses sealant to connect the base 1 and the lens 3, improving the connection stability between the base 1 and the lens 3, simplifying the processing technology, and being able to effectively reduce the defective rate.

[0040] In one embodiment, the number of the first connection hole 12 , the number of the second connection hole 31 and the number of the fastener 4 are all two, which ensures that the base 1 and the lens 3 are reliably connected together while reducing the cost.

[0041] In one embodiment, the number of the first connection holes 12 , the second connection holes 31 and the fasteners 4 may be three or more.

[0042] See also Figure 3 In one embodiment, the lens 3 has a wire outlet 32, and the wire outlet 32 ​​is for the wires of the circuit board 2 to pass through, and a sealant (not shown in the figure) is provided between the wire outlet 32 ​​and the wires of the circuit board 2, and the sealant seals the wire outlet 32 ​​to reliably seal the wire outlet 32, thereby completely sealing the space enclosed by the base 1 and the lens 3, and improving the waterproof performance of the circuit board 2.

[0043] In one embodiment, the wire outlet 32 ​​is located on a side close to the bottom of the lens 3 and penetrates the bottom opening of the lens 3 , and the sealant is located between the wire outlet 32 ​​and the sealing member 5 .

[0044] See also Figure 3 and Figure 4 In one embodiment, the base 1 is further provided with a positioning groove 13, and the positioning groove 13 cooperates with the seal 5. In this way, by arranging the seal 5 in the positioning groove 13, the seal 5 can be installed and positioned, and the seal 5 can be quickly installed. At the same time, it is ensured that the seal 5 is installed at the set position, so that the seal 5 can reliably seal the gap between the base 1 and the lens 3, which can improve the sealing reliability and have higher waterproof performance.

[0045] In one embodiment, the seal 5 is a sealing ring, and the seal 5 of the sealing ring structure has a certain supporting performance. During installation, the seal 5 with a certain supporting performance is easier to insert into the positioning groove 13, which can reduce the difficulty of installation, thereby improving the installation efficiency and making the installation more convenient. In other embodiments, the seal 5 is a sealing tape.

[0046] In one embodiment, the sealing member 5 is a structure made of a silicone material. In other embodiments, the sealing member 5 can be a structure made of other materials in rubber.

[0047] See also Figure 4 In one embodiment, the seal 5 is sleeved on the outer peripheral wall of the mounting portion 11, so that the inner ring of the seal 5 is positioned by using the mounting portion 11, and the seal 5 is restricted from moving toward the center of the mounting portion 11, thereby ensuring that the seal 5 is installed at the set position, and the structural reliability is higher.

[0048] See also Figure 3-Figure 4In one embodiment, the base 1 is further provided with at least two connecting columns 14, and the connecting columns 14 have first connecting holes 12;

[0049] The outer wall of the seal 5 has at least two positioning notches 51, and each positioning notch 51 corresponds to each connecting column 14. In this way, the outer ring of the seal 5 can be positioned by making the positioning notches 51 cooperate with the connecting column 14, thereby limiting the outward movement of the seal 5 and ensuring that the seal 5 is installed at the set position, thereby increasing the structural reliability.

[0050] See also Figure 3-Figure 4 In one embodiment, the fastener 4 is provided with a limit portion 41 and a connection portion 42 connected to each other, the limit portion 41 abuts against the lens 3, and the connection portion 42 sequentially penetrates the second connection hole 31 and the first connection hole 12 and is screwed with the first connection hole 12. In this way, the second connection hole 31 and the first connection hole 12 are connected by the connection portion 42 to realize the connection between the base 1 and the lens 3. At the same time, the limit portion 41 abuts against the lens 3 to ensure that the connection portion 42 is reliably connected to the second connection hole 31 and the first connection hole 12, which can enhance the connection stability between the base 1 and the lens 3 and improve the structural reliability.

[0051] In one embodiment, one of the mounting portion 11 and the circuit board 2 is provided with a positioning groove 22, and the other is provided with a positioning protrusion 15. The positioning protrusion 15 cooperates with the positioning groove 22 to position the circuit board 2 so that the circuit board 2 can be reliably mounted on the base 1, thereby ensuring the working reliability of the waterproof lamp.

[0052] In one embodiment, the number of the positioning grooves 22 and the number of the positioning protrusions 15 are both two, the two positioning grooves 22 are arranged at intervals, and each positioning protrusion 15 is matched with each positioning groove 22 in a one-to-one correspondence.

[0053] In other embodiments, the number of the positioning groove 22 and the number of the positioning protrusions 15 can be one or three or more.

[0054] See also Figure 1-Figure 4 In one embodiment, the waterproof lamp further comprises:

[0055] The housing 6 is disposed on the base 1. The housing 6 at least covers the connection between the base 1 and the lens 3. The housing 6 has a relief opening 61. The relief opening 61 cooperates with the upper portion of the lens 3 and allows the upper portion of the lens 3 to be exposed, so that the light from the light source 21 can pass through the outside. Since the housing 6 at least covers the connection between the base 1 and the lens 3, it is more difficult for water to enter the connection between the base 1 and the lens 3 from the outside, thereby increasing the difficulty for water to enter the space surrounded by the base 1 and the lens 3, which can play a certain waterproof role and enhance the waterproof performance.

[0056] In one embodiment, the housing 6 and the base 1 are connected together by snapping, which ensures that the housing 6 and the base 1 are reliably connected together and improves the installation efficiency of the housing 6 on the base 1.

[0057] In other embodiments, the housing 6 and the base 1 may also be connected together by bolting, welding, fusion or other connection methods.

[0058] A preferred embodiment of the present utility model further provides a point light source lamp, including the above-mentioned waterproof lamp.

[0059] The point light source lamp of the utility model, due to the adoption of the above-mentioned waterproof lamp, can also achieve the gap between the base 1 and the lens 3 without sealing with sealant, replacing the connection method of the prior art that uses sealant to connect the base 1 and the lens 3, thereby improving the connection stability between the base 1 and the lens 3, simplifying the processing technology, and being able to effectively reduce the defective rate.
