Outdoor lighting needs to withstand the test of ice, snow, scorching sun, wind, rain, and thunder for a long time, and the cost is high. Because it is difficult to dismantle and repair the outer wall, it must meet the requirements of long-term stable work. The LED is a delicate semiconductor component. If it is wet, if it is not waterproof led light, the chip will absorb moisture and damage the LED, PCB, and other components. To ensure long-term stable operation of LEDs in harsh outdoor conditions, the waterproof structure design of lamps is extremely critical, so it is necessary to use the waterproof led light.

At present, the waterproof technology of waterproof led light lamps is mainly divided into two directions: structural waterproofing and material waterproofing. The so-called structural waterproofing means that after the various structural components of the product are combined, the waterproofing function is already available. The waterproofing of the material means that when designing the product, the position of the potting glue to seal the electrical components is reserved, and the glue material is used to achieve waterproofing during assembly. The two waterproof designs are suitable for different product routes and have their own advantages.
Ultraviolet rays are one of the factors that affect the waterproof performance of lamps and lanterns. Ultraviolet rays have a damaging effect on the wire insulation layer, protective coating of the casing, plastic parts, potting glue, sealing rubber strips, and adhesives exposed to the waterproof led light.
After the insulation layer of the wire is aged and cracked, the water vapor will penetrate into the interior of the lamp through the gap of the wire core. After the shell coating of the waterproof led light is aged, the coating on the edge of the shell is cracked or peeled off, and there will be gaps. As the plastic casing ages, it will deform and crack. The aging of the electronic potting colloid will cause cracking. The sealing rubber strip is aging and deformed, and there will be gaps. The adhesive between the structural parts is aging, and gaps will also appear after reducing the adhesion. These are the damages of UV rays to the waterproof ability of lamps.
Through the above introduction and analysis of the characteristics of the waterproof led light, hope it helps you.
