The popularization and use of street lights in severe cold areas is a very simple and overlooked problem is because ice and snow accumulate on the surface of the lamps, and the ice is formed after being heated and melted. Once the ice is formed, it will pose a very big safety hazard to vehicles and pedestrians. Especially for LED street lamps, because the lamp housing is made of aluminum, the aluminum oxide on the surface is attributed to the hydrophilic material, which is more likely to cause ice coagulation.
Because it affects the safety of road traffic, preventing ice condensation is a safety measure that must be taken into consideration when using road LED street lights in severe cold areas. If the LED lamps only use materials with excellent hydrophobic function, the effect of preventing ice aggregation is not ambition, and even water can freeze very hard on the surface of some materials. Because the material with good hydrophobic function can delay the icing process, it cannot prevent the formation of ice.
However, not all LED street lights will cause ice agglomeration, as long as the appearance of the lamp is smooth, smooth and flat; there is no ice, snow or water accumulation bearing structure; the LED street lamp with excellent hydrophobic function of the surface material will not cause ice agglomeration, so we When purchasing, you must carefully choose such LED street lights.
