Product Description

Applicable place 

Widely applied in general lighting and operation lighting in hazardous environments of oil exploitation, oil refining, metal smelting, chemicals, military, coal mines, thermal power stations, wineries, etc. 

Applicable for Zone 1, Zone 2, Class IIA, Class IIB and Class IIC explosive gas environments and flammable dust environments as well as Zone 21 and Zone 22 flammable and explosive sites. 

Product Features
Light source module:

High brightness LED light source, with high efficiency cross-flow drive power supply, save up to 60% than gas discharge lamp, LED components are all closed, waterproof and dustproof, highest internal cleaning and maintenance, circuit substrate thermal resistance is low, specially designed template circuit, each unit fault will not affect the normal work of the rest of the components.

Power module:

High efficiency cross-flow drive power supply with intelligent power, modulator, with light flux compensation function, reduce light decay, ensure the LED light efficiency, with overvoltage protection, overcurrent protection stage surge current protection function.

Cooling module:

Explosion-proof lamp shell using aluminum alloy high pressure raise cause model, surface after shot high voltage electrostatic spraying, effectively improve the performance of radiator shell, substrate aluminum alloy shell, point heat source can be instantly transformed into plane heat source, heat dissipation area multiplied, heat disperse quickly, improve the efficiency of heat dissipation, shell surface has the airflow grooves, with the aid of air flow take away heat, high density of heat dissipation scales and greatly increase the cooling area, fully guarantee the LED heat dissipation requirements, longer service life.

Light distribution module:

For each type of lamps and lanterns is special one-piece structure design, the power supply cavity has a hinge, more convenient installation of lamps and lanterns, this series lamps and lanterns is belong to product of free maintenance, energy conservation, environmental protection, wall installation rotation Angle is adjustable, cable wiring, type suction a top, embedded installation immediately by cable and steel pipe wiring, exposed fasteners high anticorrosion performance of stainless steel material.

LED explosion-proof lights are high-efficiency high-power LED light source with accurate light distribution design, together with 99.99% high-purity aluminum reflector cup and 93% transparent PC imported parts with light transmittance. The efficiency of lamps is up to 79%, which is more than 40% higher than the industry level.
Advanced and reasonable circuit design, with high-quality components, electrical efficiency up to 90%, higher than the industry level of more than 6%.
Efficient light source + efficient light distribution + efficient circuit, more than 50% energy saving than the industry level. Reduce maintenance effort
According to the national military standard quality control system, after strict reliability and aging test, the lamp failure rate is lower.

After-sales guarantee

Strictly in accordance with ISO9001:2008 quality assurance system for quality control, all the raw materials and accessories are superior.
The product is guaranteed for 5 years. If there is any quality problem in the first 3 years, we will replace the same kind of new products unconditionally, and the next 2 years will be repaired free of charge (except for man-made damage and natural disasters).
