Three proofing lamps refer to the three proofs of water, dust and corrosion. Special anti-oxidation and anti-corrosion materials and silica gel sealing ring are used to meet the protection requirements of lamps. This lamp carries out anti-corrosion, waterproof and anti-oxidation treatment on the circuit control board. According to the characteristics of weak sealing and heat dissipation of the electrical box, the intelligent temperature control three anti lamp special working circuit reduces the working temperature of the power converter, isolates the protective circuit for strong current and double insulates the connector to ensure the safety and reliability of the circuit. According to the actual working environment of the three proofing lamp, the surface of the lamp protection box is treated with nano spray, moisture-proof and anti-corrosion treatment to prevent dust and moisture from entering.
