1. What are the factors that affect the waterproof performance of street lights

1. Ultraviolet

Ultraviolet rays have damaged effects on the insulating layer of the wires, shell protection coatings, plastic parts, sealing glue, sealing rubber strips, and adhesives exposed to the street lights.

After the insulation layer of the wire is cracked, the water vapor will penetrate the inside of the lamp through the gap of the wire core.After the lamp shell is coated with aging, the coating of the edge of the shell will crack or strip, and there will be gaps.After the adhesive gum aging between the electronic sealing collagen, the sealing glue strip, and the structural parts, the adhesion, deformation, cracking, and the gap will also be reduced in order to reduce the waterproof performance.

2. High and low temperature

The temperature of the Outdoor daily changes greatly. The surface temperature of the summer lamps during the summer can rise to 50-60 C, and it will fall to 10-20 C in the evening. The temperature of the ice and snow in winter can be reduced to zero, and the temperature difference between the year will change greater.Under the high temperature environment of Outdoor street lights, materials will accelerate aging and deformation.When the temperature drops to zero, the plastic parts become crispy, and it may crack under the pressure of cold air.

3. Hot expansion and contraction

The shell of the outdoor lamps will cause thermal expansion and contraction due to changes in temperature. The lineflation coefficients of different materials will be different. The two materials of glass and aluminum profiles will displacement at the combination.The process of thermal expansion and contraction is continuously repeated, relative displacement is repeated, and the air density of the lamp is greatly damaged, the gas density is poor, and the waterproof performance is greatly reduced.

2. How to deal with Outdoor street lights and waterproof

At present, Outdoor street lights are mainly divided into two major directions: structural waterproof and material waterproof. Structural waterproof is to improve the structural protection performance of the lamp body and enable it to cope with the harsh Outdoor environment.The position of glue density electrical components is used to prevent waterproof with glue material during assembly.The treatment method of Outdoor street light waterproof treatment is specifically:

1. waterproof waterproof at the imported line hole

The entry and exit line of Outdoor street lights is the easiest place to enter the water. Therefore, the screws and nuts of this part must be tightened in place. The entry and exit cable cannot be easily pulled out. You can use the Gaza Belt, glue and other methods to be fixed.If the lamp is buried underground or in water, then it is allocated at the bottom. The occasions used are that the lamp body is more infiltrated by water, and the import line must be increased.

2. glass splitting waterproof

If there is a glass rubber ring, first fix the groove of the tank or rely on the edge of the lamp body or the light in the lamp to play a small amount of uniform waterproof glue to increase the squeezing and sealing of the rubber ring when the tightness is tightly locked;If there is no glass rubber ring, first in the glass gum, the waterproof glue is placed obliquely.

3. Cover the glue ring to fight screw waterproof

First consider the fixed rubber ring. Generally, the lamp body has no glue groove. The thickness of the rubber ring and the side of the screw hole is fixed first; if the lamp body has a glue groove, first play a small amount of glue in a circle in a circle.Fix the rubber ring first; for the lamp body with waterproof structural waterproof, it is also necessary to evenly beat some glue on the surface and side of the tape.
