Tri-proof LED means: waterproof, dust proof, anti-corrosion these three defenses. Use special anti-oxidation anti-corrosion materials and silicone seals to achieve the protection requirements of the lamps. This light carries on the anti corrosion, waterproof, anti-oxidation treatment to the circuit control board, to the electrical box seals the heat-dissipating ability to be weak, the intellectual temperature control Tri proof LED special-purpose working circuit, has reduced the power frequency converter operating temperature, to the strong electric isolation protection road, The double insulation treatment of the connector ensures the safety and reliability of the circuit. According to the actual working environment of the tri proof LED, the surface of the protective box of the lamp is sprayed with moisture-proof and anti-corrosion treatment on the surface to prevent dust and moisture from entering.
