With the rapid development of petroleum, chemical, mining and other industries, lighting fixtures are more and more widely used in production, storage, and rescue, and there are more and more varieties. How to prevent the accidental explosion of lighting fixtures in explosive gas dangerous places has become a very important issue.

Since lighting fixtures inevitably generate electric sparks or form hot surfaces during operation, once they meet the explosive gas mixture at the production or rescue site, it will lead to an explosion accident, directly endangering the lives of national property and citizens. Therefore, as the most widely used lighting fixture, its explosion-proof technology has already attracted widespread attention and great attention.

Explosion proof light fixtures refer to lamps that are used in dangerous places where flammable gases and dust exist, and can prevent arcs, sparks and high temperatures that may be generated inside the lamp from igniting flammable gases and dust in the surrounding environment, so as to meet explosion-proof requirements. Explosion proof light fixtures, explosion-proof lighting. Different flammable gas mixture environments have different requirements for the explosion-proof level and explosion-proof form of explosion proof light fixtures.

Ⅰ. The scope of application of explosion proof light fixtures

1. It is suitable for dangerous places in Zone 1 and Zone 2 of explosive gas environment;

2. Suitable for IIA, IIB, IIC explosive gas environment;

3. Suitable for combustible dust environment 20 zone, 21 zone, 22 zone;

4. It is suitable for the environment with temperature group T1~T6.

Ⅱ. The performance characteristics of explosion proof light fixtures

1. Explosion-proof function: The product is strictly in accordance with the requirements of GB3868-2000 (electrical equipment used in explosive gas environments) and other relevant standards, and can work safely in flammable and explosive places.

2. Light efficiency and energy saving: gas discharge light bulbs and high reflectivity mirror reflectors are selected, which have high light efficiency, long life, large lighting range and high brightness; two kinds of light bulbs, metal halide lamp and high pressure sodium lamp, and various powers can be adjusted according to the working environment, The actual needs of lighting characteristics and light intensity are optional.

3. Applicable environment: The shell is made of high-strength alloy materials and precise structural design, which has high resistance to strong collision and impact, optimized structural design and surface treatment, good waterproof performance, and can resist water immersion and violent waves. Excellent corrosion resistance.

4. Installation method: various installation methods such as seat type, wall hanging, hanging, ceiling can be selected; the lamp head takes the end of the lamp holder bracket as the axis, which can be rotated 360° for lighting, and can be rotated left and right within a range of 16° Lighting to meet the needs of different work sites for lighting angles. The universal pipe thread cable entry port can adapt to the entry of cables with different wire diameters of Φ8~14mm; multiple cable entry ports can realize the parallel connection of multiple lights, which is suitable for layout engineering lighting.
