Waterproof Panel Light mainly achieves waterproof function through the following structural designs:
1. Shell sealing structure
The shell of Waterproof Panel Light is the first line of defense for waterproofing. Usually, an integral sealed shell is used, and the shell material is generally plastic or a composite material of metal and plastic. For plastic shells, PC (polycarbonate) or ABS (acrylonitrile-butadiene-styrene copolymer) materials with good waterproof performance are often used. These materials themselves have certain waterproof properties, and can be used to produce seamless shell structures through processes such as injection molding, reducing the gaps where moisture may invade.
Sealing structures will be designed at the edges and joints of the shell. For example, a rubber sealing ring is used. At the joints of the shell or the joints between the lampshade and the lamp body, the rubber sealing ring can fill the gap. When the lamp is installed, the sealing ring will fit tightly under the action of pressure to form a sealed barrier to prevent moisture from entering the interior of the lamp from these parts.
2. Translucent cover sealing design
The translucent cover is an important part of the panel light. It must not only ensure good light transmittance, but also have waterproof function. Generally, sealant is used to bond the light cover to the outer shell of the lamp body. This sealant has good water resistance and sealing properties, and can prevent moisture from penetrating from the gap between the light cover and the lamp body.
In addition, the light cover of some waterproof panel lights is also a special waterproof structure. For example, double-layer or multi-layer light-transmitting materials are used, and the middle is treated by a special sealing process. Even if the outer layer is impacted or soaked by water, the inner layer can still remain dry to ensure that the light is normally transmitted.
3. Sealing protection of internal components
In the panel light, key components such as circuit boards also need to be waterproofed. A common practice is to coat the circuit board with waterproof glue. This waterproof glue can form a protective film on the surface of the circuit board to isolate moisture and prevent short circuits and other faults caused by moisture contacting the circuit board.
In addition, special waterproof connectors are used for interface parts such as power cords. These waterproof connectors usually have rubber sealing plugs or sealing sleeves. After the power cord is inserted, it can tightly wrap the power cord to prevent moisture from entering the interior of the lamp from the interface.
