FIGS. 1-6 illustrate a waterproof lamp according to a preferred implementation of the present disclosure. The waterproof lamp includes:

    • a base 1 provided with a mounting portion 11 and a first connecting portion 12;
    • a circuit board 2 arranged on the mounting portion 11, the circuit board 2 being electrically connected to a light source 21;
    • a lens 3 having a lower portion resting over the base 1, where the lens 3 is arranged around the mounting portion 11, an accommodating cavity is formed between the lens 3 and the base 1 and configured to accommodate the circuit board 2, the lens 3 is provided with a second connecting portion 31, the second connecting portion 31 is connected to the first connecting portion 12 so as to fix the lens 3 and the base 1 together, and the lens 3 is configured to transmit light emitted by the light source 21 to the outside; and
    • a sealing structure arranged around the mounting portion 11, the sealing structure being arranged between the base 1 and the lens 3 and configured to seal a gap between the base 1 and the lens 3 so as to allow the circuit board 2 to be mounted in the accommodating cavity in a sealed manner.


In the waterproof lamp according to the present disclosure, the circuit board 2 is arranged on the mounting portion 11 to enable the circuit board 2 to be mounted on the base 1, and the accommodating cavity is formed between the lens 3 and the base 1 to accommodate the circuit board 2 so as to enable the circuit board 2 to be encapsulated inside the waterproof lamp. Since the base 1 and the lens 3 are fixedly connected together by a connecting structure composed of the first connecting portion 12 and the second connecting portion 31, the base 1 and the lens 3 can be reliably fixed together, achieving a higher structural reliability. In addition, since the sealing structure is arranged around the mounting portion 11 and can seal the gap between the base 1 and the lens 3, the circuit board 2 can be reliably mounted in the accommodating cavity in a sealed manner, instead of the sealed mounting of the circuit board 2 by means of filling an adhesive into the interior of a housing 5 in the prior art, such that the processing process is simplified and the defective rate can be effectively reduced, and the stability of a connection between the base 1 and the lens 3 is also improved, resulting in a higher reliability of sealing the circuit board 2.


Referring to FIGS. 2-4, in an implementation, the sealing structure includes a seal ring 41. The seal ring 41 is sandwiched between the base 1 and the lens 3 to allow the seal ring 41 to be pressed against the base 1 and the lens 3 by tension forces from both of the first connecting portion and the second connecting portion, so as to cause a bottom surface of the seal ring 41 to come into close contact with the base 1 and to cause a top surface of the seal ring 41 to come into close contact with the lens 3, achieving the sealing of the gap between the base 1 and the lens 3 without a sealing adhesive 42, so that the structural reliability is high, and the mounting efficiency can be increased without waiting for the adhesive to become dry.


Referring to FIGS. 3 and 4, in an implementation, the base 1 is further provided with a positioning groove 13. The positioning groove 13 is arranged around the mounting portion 11, and the positioning groove 13 fits with the seal ring 41. In this way, the seal ring 41 can be mounted and positioned in place by arranging the seal ring 41 in the positioning groove 13, enabling quick mounting of the seal ring 41, while ensuring that the seal ring 41 is mounted in a set position, thereby enabling the seal ring 41 to reliably seal the gap between the base 1 and the lens 3, such that the reliability of sealing can be improved, resulting in a better waterproof performance.


Referring to FIGS. 3-4, in an implementation, the base 1 is further provided with a connecting post 121.


The seal ring 41 has a retaining notch 411 in a peripheral wall, and the retaining notch 411 fits with the connecting post 121.

The sealing structure includes a sealing adhesive 42, and the sealing adhesive 42 covers the adhesive groove 14 so as to fixedly connect the base 1 to the third connecting portion 33. Such a structure enables the sealing of the gap between the base 1 and the lens 3, and also enhances the stability of the connection between the base 1 and the lens 3, resulting in a higher waterproof stability. In addition, sealing is achieved only by filling an adhesive in the adhesive groove 14, which reduces the amount of adhesive used and reduces the cost. Moreover, the assembly process is simple, the yield rate is high, and the mounting efficiency is high.


Referring to FIG. 6, in an implementation, the base 1 is provided with a raised ring 15, the raised ring 15 is located outside the mounting portion 11 and surrounds the mounting portion 11, and the adhesive groove 14 is formed between the raised ring 15 and the mounting portion 11. With the above structure, the structure is simple, and the adhesive groove 14 is manufactured more easily and efficiently. In other implementations, no raised ring 15 may be provided on the base 1, and the adhesive groove 14 is of a recessed structure in the base 1.


In other implementations, the sealing structure may further include a sealing adhesive tape sandwiched between the base 1 and the lens 3, which can also achieve reliable sealing of the gap between the base 1 and the lens 3 to mount the circuit board 2 in a sealed manner.
