Corrosion Resistance of LED Lights

The lifespan of LED lights is affected by many factors, including heat, corrosion, water resistance and dust resistance. In the first place, factors such as sun, rain and sea water are the external elements that can corrode the body and electrical wire of the LED lights. However, internal factors such as lead frame substrates, light impermeability, converter phosphor material, and encapsulation method should also be considered. To prolong life and reduce maintenance cost, LED lights must be equipped with the ability to withstand harsh environments, especially places such as the oil and gas industry, wharf, trucking and manufacturing. For the oil and gas industry, seawater is the main cause of corrosion. Lights need to be not only waterproof but also anti-corrosion. Docks should likewise be waterproof and anti-corrosion. Corrosion in the trucking industry and manufacturing is commonly caused by exposure to bad weather.

What is Corrosion?

Corrosion is the wear of metal or metal alloys by oxidation or other chemical effects. For example, rusting of iron and oxidation of aluminum are examples of corrosion.

Environmental Factors

Humidity, oxygen, temperature, and most air pollutants are common factors that cause corrosion.

LED Light Factors

LED lights perform to a high waterproof rating and IK rating. Performance drops sharply if the LED light corrodes and reacts with the environment. The best way to prevent corrosion is LED lights isolated from hazardous materials. Much attention should be paid to the structure and material strength of the LED light.

How to Prevent Corrosion?

LED lights must be isolated from hazardous materials and the environment to prevent corrosion. The first way to control corrosion is to know how and why corrosion occurs, the second is the corrosion process and the reaction of LED light with the environment.

Material Selection

Long-lasting, environmentally friendly, reliable, high-quality materials, beautiful workmanship are important steps against corrosion.
