The three-proof lamp refers to: waterproof, dust-proof, and anti-corrosion.
Special anti-oxidation and anti-corrosion materials and silica gel sealing ring are used to achieve the protection requirements of lamps.

Tri-proof lights are generally used in places with strong corrosiveness, dusty, and damp industrial lighting requirements, such as: food factories, power plants, steel, petrochemicals, ships, venues, warehouses, parking lots, basements, etc.

PC protective shell
QLED tri-proof lamp shell and tube lamp shell are made of high-quality PC materials. Polycarbonate (PC) is a new type of thermoplastic with a transparency of 90% and is known as a transparent metal.
It is rigid and tough, has high impact strength, high dimensional stability and a wide range of use temperature, good electrical insulation performance and heat resistance, and excellent thermal performance of non-toxic PC, which can be at -100 ℃ Long-term use between -130℃, the embrittlement temperature is below -100℃.
Silicone sealing ring
The sealing ring of the QLED liquid-cooled tri-proof lamp is made of high-sealing silica gel, which has excellent sealing performance.
High temperature and low temperature resistance
It can be used for a long time in the temperature range of -60 degrees to +200 degrees.
High tightness
It has good tension, flexibility, excellent insulation and pressure resistance.
Environmental friendly
Stable chemical properties/environmental protection/no peculiar smell

New liquid-cooled drive
Generally, the drive of ordinary lamps stops working under the influence of low temperature of -15℃. QLED is filled with special liquid to protect the drive, which can withstand huge temperature changes. The electrolytic capacitor can still be maintained at low temperature, so that the drive can be driven even at -40℃. The following extreme cold temperatures can also be activated instantly.
The special liquid is added with the antifreeze component, which has the characteristics of low temperature antifreeze and high temperature anti-boiling.
