Tri-proof lights are specialized luminaires designed for harsh environments, specifically referring to special lighting fixtures that integrate three core protective functions: Waterproofing, Dustproofing, and either Corrosion Resistance (or Vibration Resistance).

Waterproofing: Typically achieves a protection rating of IP65 or higher (e.g., IP66 withstands powerful water jets, IP67 allows temporary immersion). This makes them ideal for damp, rainy, or splash-prone environments like food processing plants or car washes.

Dustproofing: Features a tightly sealed construction that effectively prevents the intrusion of dust, metal filings, and other solid particulates. This ensures stable operation of the internal circuitry in dust-intensive areas such as mines or warehouses.

Corrosion Resistance / Vibration Resistance:

Corrosion Resistance: The housing utilizes corrosion-resistant materials (e.g., engineering plastics, aluminum alloy, stainless steel) combined with special treatments (e.g., nano spray coating) to effectively resist erosion from acids, alkalis, salt spray, and other corrosive agents. This is essential for corrosive environments like chemical plants or marine settings.

Vibration Resistance: Incorporates internal damping structures and uses shock-absorbing materials (e.g., silicone seals, flexible connectors) to ensure long-term reliable operation under continuous or strong vibration conditions, such as near machine tools or in power plants.
