How to Ensure Waterproof Function of Led Solar Street Light?

LED solar street lights are being installed in more and more countries. They are favored by people due to the energy-saving and green advantages. They are exposed to the outdoor environment all year round, wind and rain, and even face the attack of thunder and typhoons. So how do solar street light manufacturers use technology to make LED solar street lights waterproof?

The waterproof of LED solar street lights is divided into two parts, one is the waterproof of the controller, and the other is the waterproof of the LED street lamp head.

1. Waterproof of the controller

The waterproof of the controller is particularly important, because the controller is the core part of the led solar street light. During the day, the controller converts solar energy into electrical energy, and at night the battery provides electrical energy to the street lamps. The waterproof of the controller means that the circuit board of the led solar street light is treated with a tri-proof insulating paint during installation, so that rainwater will flow away along the edge of the controller. During construction, attention should also be paid to bending and fixing the internal connecting wires of the controller terminals into a "U" shape. The connecting wires exposed to the outside are also fixed to a "U" shape, so that rainwater cannot enter and cause the controller to short-circuit. In addition, waterproof glue can be applied to the inner and outer line interfaces to waterproof. If waterproofing is done well, the service life of led solar street lights can reach 10 years. If the waterproofing is not done well, generally after 3 years of use, the controller will have a short circuit. Therefore, the waterproofing of the led solar street light controller will directly affect the service life of the led solar street light.

2. Waterproof of LED solar street light head

The waterproof of LED street lamp head is also very important. Only by doing a good job of waterproofing the lamp head can the stability and safety of the LED street lamp lighting at night be guaranteed. The exterior design of the LED solar street light housing should not be concave, try to choose the online through-hole style, which is conducive to the rapid evaporation of water from the LED solar street light housing.

LED solar street light chips and lenses must consider their waterproof performance and reach IP66 level ( only for high performance solar led street lamp). The back cover of the street lamp head, the back cover of the power supply box, and the threading hole in the power supply box are respectively made of waterproof rubber strips and waterproof plugs with good sealing performance.

It is necessary to do a good job in the aging detection of LED solar street light caps. The waterproof rubber strip at the internal joint of the LED street lamp has a service life, and the sealing performance of the joint may decrease after a few years. Therefore, LED solar street lamp manufacturers must perform aging testing after production to test their waterproof performance to ensure that the waterproof performance is good for at least 5 years.

The above are some ways to do a good job of waterproofing LED solar street lights. Of course, when you purchase LED solar street lights, do not choose products produced by small workshops. First, because the small workshops have less production equipment and poor craftsmanship, most of the LED street lights waterproof work is not good, and you must do it from a reliable LED solar street light manufacturer. Solar light price is not the only point that you should focus on.
