Moreover, like the material of the product's power cord, it has good adhesion. Therefore, most LED lights use PVC material. Some integrated lens modules currently on the market are only waterproof to IPX6 or even lower after being injection-molded with PVC rubber. In addition, the joints between PVC and PC lenses are easy to separate (manifested in separation by hand tearing and separation during the thermal expansion and contraction stage of long-term use of the product). Therefore, there is room for improvement. Summary of the Invention

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. The schematic embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0019] like Figure 1-5 As shown: The utility model of the high-performance injection-molded waterproof module of the LED lamp includes a lens 1, a lens shell 2, a light source PCB board 3 and an injection-molded plastic shell 4. The lens 1 and the lens shell 2 are integrally formed, the light source PCB board 3 is located in the lens shell 2, and the edge of the lens shell 2 is fixedly connected to the edge of the injection-molded plastic shell 4 through a waterproof structure.

[0020] Furthermore, the waterproof structure includes a side flange portion 5 and a lower flange portion 7, the side flange portion 5 is arranged at the outer edge of the lens housing 2, and the lower flange portion 7 is arranged at the lower end edge of the lens housing 2, the side flange portion 5 and the lower flange portion 7 are integrally formed with the lens housing 2, and the edge of the injection molded shell 4 covers the side flange portion 5 and the lower flange portion 7.

[0021] Preferably, the upper edge of the side flange portion 5 is provided with a waterproof slope structure 6 inclined inward.

[0022] As an improvement, double-sided anti-slip grooves 8 are provided on both sides of the lens housing 2. The double-sided anti-slip grooves 8 are provided on the side flange portion 5. The double-sided anti-slip grooves 8 are a groove structure that is wide inside and narrow outside. There are multiple double-sided anti-slip grooves 8, and multiple double-sided anti-slip grooves 8 are evenly distributed on both sides of the lens housing 2.

[0023] As an improvement, both ends of the lens housing 2 are provided with anti-slip ears 9 , which are fixedly connected to both ends of the lens housing 2 and are covered in the injection molded shell 4 .

[0024] The working principle of this utility model is as follows:

[0025] During production, the present invention provides a side flange portion 5 on the side of the lens housing 2, and a waterproof slope structure 6 on the upper end of the side flange portion 5. The outer side of the lens housing 2 and the waterproof slope structure 6 form a first layer of waterproof structure. A lower flange portion 7 is provided at the lower end of the lens housing 2. The lower end of the side flange portion 5 and the outer side of the lower flange portion 7 form a second layer of waterproof structure. The lower end of the lower flange portion 7 forms a third layer of waterproof structure. During installation, first, the lens 1, the lens housing 2, the side flange portion 5, and the waterproof slope structure 6 are integrally injection molded. After the light source PCB board 3 is placed in the lens housing 2, the lens housing 2 is placed in a mold, and the injection molded plastic shell 4 is formed by injection molding. At this time, the injection molded plastic shell 4 After the edge of the lens shell 2 is wrapped, it can achieve the IPX7 waterproof level. In order to increase the connection strength between the injection molded shell 4 and the lens shell 2, double-sided anti-slip grooves 8 and anti-slip ears 9 at both ends are set. The shape of the double-sided anti-slip grooves 8 is a groove that is wide inside and narrow outside. When the injection molded shell 4 is injected, the structure of the injection molded shell 4 enters the double-sided anti-slip grooves 8 to form a structure that matches the shape of the double-sided anti-slip grooves 8, thereby preventing the injection molded shell 4 from falling off. Anti-slip ears 9 are set at both ends of the lens shell 2. When the injection molded shell 4 is injected, the structure of the injection molded shell 4 is injected into the holes of the anti-slip ears 9 at both ends to form a strong structure, further improving the connection strength between the injection molded shell 4 and the lens shell 2.
