What is the explosion proof light
Sep 26, 2021
Definition of explosion proof light.

explosion proof light is a lamp used in hazardous locations where flammable gases and dusts exist, which can prevent the arcs, sparks and high temperatures generated within the lamp from igniting flammable gases and dusts in the surrounding environment, thus meeting the explosion proof requirements. Different flammable gas environments have different requirements for the explosion-proof level and form of explosion-proof lamps.

With the rapid development of petroleum, chemical, mining and other industries, lighting is more and more widely used in production, storage and rescue, and more and more varieties are appearing in explosive gas hazardous places, how to prevent accidental explosion of lamps and lanterns has become a very important topic. Since lighting equipment will inevitably generate electric sparks or form scorching surfaces during operation, once they encounter explosive gas mixtures at production or rescue sites, they will cause explosive accidents and directly endanger the lives of citizens and the safety of national property. Therefore, as the most widely used lamps and lanterns, its explosion-proof technology has attracted widespread attention and great importance.

The scope of application of explosion proof light.

1. Suitable for hazardous places in Zone 1 and Zone 2 of explosive gas environment.

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

3. Suitable for Zone 20, Zone 21, Zone 22.

4. Suitable for temperature group T1-T6 environment.

The performance characteristics of explosion proof light.

1.Ouhui Lighting explosion proof light is equipped with 1W high power LED lamp beads. The light source is energy efficient, more than 70% energy saving than ordinary fluorescent lamps.
Through the unique light distribution design, you can precisely control the light type and luminous angle of the LED light source to avoid light pollution and ineffective light utilization. The light is soft and glare-free, which will not cause eye fatigue of operators and improve the working efficiency.

2. The shell is made of lightweight aluminum alloy die-casting, and the surface is treated with high-pressure electrostatic powder coating.

3. There is a wiring cavity inside the light and there are special wiring terminals. Users can directly enter the wire during installation, no need to install a junction box, easy to install.

4. When replacing the lamp beads, you only need to remove the PCB board and install a new one.

5. Can be equipped with emergency equipment according to user requirements. The built-in lamp body is light in weight. After cutting off the external power supply, the lamp will automatically switch to the emergency lighting state.

The principle of explosion proof light.

The principle of explosion proof type is based on the explosion proof concept and fire type of the European standard EN 13463-1:2002 "Non-electrical equipment for explosive atmospheres Part 1: Basic methods and requirements". The explosion-proof type is the most commonly used explosion-proof type as measures are taken to allow internal explosion and to prevent flame propagation. Because this explosion-proof type lampshade is usually made of metal material, it has good heat dissipation, high shell strength and good durability, and is very popular among users. In addition, many higher safety explosion-proof lighting components, such as lampholders, interlocking switches, etc., also use explosion-proof construction. Electrical equipment with an explosion-proof housing is called explosion-proof electrical equipment.
