一, LED street lamp shell materials and their traits
1. Shell made of aluminum alloy
Aluminum alloy is a common material for outdoor LED street lights because it is light, lets heat escape well, and is very resistant to corrosion. The aluminum alloy housing helps the lamp beads lose heat, which makes the light source last longer. But if the anodized layer on the surface of aluminum alloy comes off or becomes scratched, it needs to be fixed right away to stop corrosion from spreading. When taking care of the aluminum alloy case,
2. Shell made of steel
The steel shell structure is strong and can handle a lot of damage, thus it's good for roadways or industrial regions with strong winds. But steel isn't very good at resisting rust, so it needs to be hot-dip galvanized or sprayed with an anti-rust layer. When taking care of the steel casing, you should check the anti-corrosion coating on a regular basis. If you find rust, you should quickly polish, paint, or cover it with anti-rust oil to make it last longer.
二,Daily cleaning and maintenance of LED street lamp casing
Cleaning the LED street lamp casings every day is the most important thing you can do to make them last longer. Over time, dust, dirt, bird droppings, and other pollutants can build up and make it harder for heat and light to escape.
1. How often to clean
Cleaning should be done at least once every three months, and every two months in locations with a lot of dust or industry. In areas with a lot of salt and moisture, like the coast or places with high humidity, the cleaning cycle can be even shorter to stop corrosion from happening faster.
2. Tools and methods for cleaning
To keep the exterior shell from getting scratched, don't use a harsh brush or steel wire ball. Instead, use a soft brush, sponge, or microfiber cloth. For tough stains, use mild neutral cleaners or soapy water, but stay away from strong acids, alkalis, and organic solvents. After cleaning, rinse out any cleaning solution that is still there with clean water and dry it with a dry cloth.
三,Corrosion and oxidation prevention measures
1. Shell made of aluminum alloy
The anodized layer on the outside of the aluminum alloy shell is what keeps it from rusting. You should check it often for peeling or scratching. You can fix local damage using an anti-corrosion coating made for aluminum alloy. Salt and other pollutants should also be cleaned up right away in coastal or heavily polluted areas.
2. Steel shell
The steel shell is likely to corrode, so you should check the spray coating often to make sure it is still strong. You can polish and paint over little rust spots, but you need to repair badly rusted portions. You can use rust-proof oil to make things less likely to rust in wet or humid places.
3. A lampshade made of plastic
Ultraviolet rays can make plastic materials age faster. To make them last longer, it is best to use UV-resistant materials or spray sunscreen on the surface.
4.composite material
To make sure that the lighting fixtures are waterproof, dustproof, and structurally sound, the composite materials should be checked often for cracks or peeling of the composite layer. If any pieces are broken, they should be replaced right once. LED street lamp casings can last longer and the lamps can keep working well if they are maintained with scientific methods that stop corrosion and oxidation.
四,Shell care in unusual places
1. An environment by the sea or with salt spray
Salt spray can speed up the rusting of metal, so the lamp's surface salt should be cleansed with fresh water on a regular basis. The steel shell should be covered with a coating that protects it from rust, and the anodized layer of the aluminum alloy should be examined.
2. A hot or industrial setting
Plastic lampshades can readily age in high temperatures, but you can use materials that resist high temperatures or install sunshades. The industrial area has a lot of dust, thus the cleaning schedule should be changed so that the radiator can have enough air flow.
3. A cold or wet place
To keep rain and snow from getting inside the lamp body, check the sealing ring and waterproof performance of the lamp body. You can put antifreeze materials in plastic lampshades to keep them from cracking.
五, Suggestions for regular inspections and maintenance
Setting up a systematic inspection and maintenance system is the best way to make sure that LED street lights work well for a long time.
1. Full inspection cycle: once every six months, with a focus on inspecting the clarity of the lampshade, shell, and sealing ring.
2. Keeping track of maintenance: Set up maintenance logs to keep track of cleaning, inspections, and replacements.
3. Fix small fractures or corrosion right once to stop them from getting worse and putting off throwing away lamps.
