Led three proof lamps, literally, are lamps with three protective functions of waterproof, dustproof and anti-corrosion. Anti oxidation and anti-corrosion materials and silicone sealing ring are selected to complete the protection requirements of lamps. The lamp carries out waterproof, anti-corrosion and anti-oxidation treatment for the circuit control board. Aiming at the characteristics of weak sealing and heat dissipation capacity of the electrical box, the lamp operates in the temperature controlled three prevention circuit, which reduces the operating temperature of the power inverter, separates the protective circuit from the strong resistance, and insulates the connector with two layers, so as to ensure the reliability of the circuit. According to the actual working environment, the surface of the lamp protection box was treated with Nano Spray moisture-proof and anti-corrosion treatment to prevent dust and moisture from entering.

The main features are as follows:

1. Anti glare function. The transparent part adopts advanced lighting optical principle to optimize the planning. The light is uniform and soft, without glare and ghosting, which can prevent the construction workers from discomfort and fatigue.

2. Light efficiency and energy saving. The selected gas discharge light source has high light efficiency and long life, which can reach 30000 hours; The power factor is greater than 0.9, the luminous efficiency is high and the light transmittance is good.

3. Very energy-saving. It belongs to DC drive and consumes very low power. Under the same lighting effect, led three proof lamp can save at least 80% energy than traditional light source.

4. Installation method: seat type, ceiling type, ceiling type and other installation methods to meet the lighting needs of different operation sites. Electronic and mechanical two-layer protection, automatically cut off the power supply after opening the cover, increasing the stability and reliability of use and protection.

5. Multi channel shockproof structure and integrated planning to ensure long-term stable operation in high frequency and multi frequency oscillation environment.

6. Long life, no loose part in the lamp body, so there is no phenomenon that the filament is easy to burn. Therefore, the service life of this lamp can reach 50000 to 100000 hours, which is more than ten times longer than that of traditional light source, greatly reducing the cost of replacement and protection.

7. High strength alloy shell is selected for special surface spraying and sealing treatment, which can be used for a long time in high temperature, humidity and various corrosive environments.

8. Led three proof lamp environmental protection: LED spectrum has no ultraviolet and infrared, low heat and no stroboscopic, no stroboscopic can protect vision, and waste can be recycled, no pollution, no mercury and other harmful elements, can contact, the real green lighting source.
