Factors affecting the effect of waterproof LED lights

1. Ultraviolet rays

Ultraviolet rays have a damaging effect on wire insulation, protective coating of casings, plastic parts, potting compounds, sealing rubber strips, and adhesives exposed to lamps.

2. High and low temperature

The outdoor temperature varies greatly every day. The surface temperature of the lamps can rise to 50-60 ℃ during the day in summer, and drop to 10-20 qC at night. In the high temperature environment of summer, the material of outdoor lamps accelerates aging and deformation. When the temperature drops below freezing, plastic parts become brittle, or crack under the pressure of ice and snow.

3. Thermal expansion and contraction

Waterproof LED lights housing thermal expansion and contraction: the change of temperature leads to thermal expansion and contraction of the lamp, different materials (such as glass and aluminum profiles) have different linear expansion coefficients, and the two materials will shift at the junction. The process of thermal expansion and contraction is repeated continuously, and the relative displacement is also repeated, which greatly damages the air tightness of the lamps.
