The 20W solar street light manufacturer divides its waterproof into two parts, one is the waterproof of the controller, the other is the waterproof of the LED lamp, the waterproof of the LED lamp is very simple, just need to make a simple lampshade, and do the waterproof just like the ordinary electric lamp, but the waterproof of the controller of the solar street lamp needs to be done very carefully because the controller of the solar street lamp It is very important to convert the solar energy in the daytime to the electric energy in the evening. Therefore, special attention should be paid to waterproof. In fact, the controller of the solar street lamp is very simple in waterproof, that is, when installing, the circuit board of the solar street lamp should be treated with a three proofing paint, and then the rainwater will slip along the edge. Therefore, the solar street lamp controller should be U-shaped tubes during production.

In fact, every 20W solar street light manufacturer uses waterproof glue to prevent water, but because the waterproof glue used by each manufacturer is somewhat different, the waterproof effect is also different. The important point of the service life of the solar street lamp is the waterproof effect. If the waterproof effect is good, the service life of the solar street lamp can reach ten years. Once the solar street lamp is not well waterproof, the water-proof effect of solar street lamp is not good Generally, after three years of use, the controller of the solar street lamp will be short-circuited, so the waterproof performance of solar street lamp is directly related to the price of a solar street lamp.
