At present, the widely used waterproof measures in the lamp market are to install silicone sealing ring or sealant: the former is to install silicone sealing ring between the upper and lower shells, and then fix the upper and lower shells with screws. This method requires a high compression amount of silicone strip, and if the design and use are unreasonable, it is easy to cause unstable sealing and water leakage or complete sealing.

[0018] The utility model will be described in further detail below with reference to the drawings.
[0019] As shown in the figure, a waterproof LED lamp, comprising a base 1 and a light-transmitting lampshade 2, the light-transmitting lampshade 2 is installed on the base 1 to form a cavity 102 for installing LED light-emitting components 5, the base 1 and the light-transmitting lampshade 2 are made of the same hot melt material, a metal wire 3 is arranged between the contact surface of the base 1 and the light-transmitting lampshade 2, the metal wire 3 is heated to the melting point of the hot melt material, so that the contact surface of the base 1 and the light-transmitting lampshade 2 is fused and bonded together, realizing the fusion of the base 1 and the light-transmitting lampshade 2 to form an integral whole.
[0020] In this specific embodiment, the hot melt material is plastic. As a kind of hot melt material, plastic is easy to melt after heating and can quickly solidify after cooling, which is suitable for rapid production and processing, and plastic has strong resistance to a variety of chemicals and solvents and can be used in harsh environments.
[0021] In this specific embodiment, the base 1 has an upwardly recessed mounting cavity 11, the light-transmitting lampshade 2 has a head-to-tail mounting wall 21, the mounting cavity 11 is upwardly recessed to be provided with a positioning clamping groove 111 matched with the mounting wall 21, the mounting wall 21 is embedded in the positioning clamping groove 111, and the metal wire 3 is arranged between the upper end surface of the mounting wall 21 and the bottom end surface of the positioning clamping groove 111. The positioning and installation between the base 1 and the light-transmitting lampshade 2 are realized.
[0022] In this specific embodiment, a plurality of support protrusions 12 are downwardly protruded in the mounting cavity 11, the plurality of support protrusions 12 are arranged at intervals around the inner side of the mounting cavity 11, and the mounting wall 21 is arranged between the support protrusions 12 and the inner side wall of the mounting cavity 11. The support protrusions 12 are used to support the mounting wall 21 of the light-transmitting lampshade 2 to improve the stability of the installation.
[0023] In this specific embodiment, the upper end surface of the mounting wall 21 is downwardly recessed to be provided with a head-to-tail upper embedding groove 211, the bottom end surface of the positioning clamping groove 111 is upwardly recessed to be provided with a head-to-tail lower embedding groove 112 matched with the upper embedding groove 211, when the light-transmitting lampshade 2 is installed with the base 1, the upper embedding groove 211 and the lower embedding groove 112 are butted to form a head-to-tail embedding installation groove 4 for embedding and installing the metal wire 3, and the shape of the metal wire 3 is matched with the embedding installation groove 4 and is embedded and installed in the embedding installation groove 4.

The contact surface of the base 1 and the light-transmitting lampshade 2 melts and is bonded together. After cooling, the two are fused into one body, which has stable waterproof performance.
