Explosion-proof lamps: description, advantages

To work in industrial enterprises, devices with increased safety requirements are required. In particular, these are lighting devices. We suggest considering luminescent and LED explosion-proof lamps - what it is and their application.

Modern lighting technologies make it possible to install high-quality and durable luminaires that provide emergency light. Depending on the programmed mode, they can operate during emergency situations or illuminate the workshop for a period of work.

Explosion Proof LED Lights

The main advantage of explosion-proof lamps is that they are made of heavy-duty housing. This is a special aluminum alloy that does not lend itself to corrosion, resists deformation, does not allow moisture and works well at high temperatures.

All luminaires in explosion-proof design are characterized by a very tight connection of parts. This is necessary so that no small parts can get into the contacts: spare parts, dust, dirt and etc. All connections are also hermetically sealed and insulated with sealant or other similar compositions.

Thanks to this design, the head lamps are protected from low and high pressure, high temperature, shock and open flame. They also have a sufficient level of vibration resistance. For example, incandescent lamps or drills can interrupt their work during movement, flash and shorten which negatively affects a person, moreover, from a similar physical impact they can explode.

Often, to work in hazardous areas where ceiling lamps are not applicable, portable lights are needed with a battery or solar panels GOST 52065-2003. They do not require installation, and their lighting parameters practically do not differ from stationary devices. A portable or wall lamp is also made entirely of heavy-duty metal with heat-resistant glass.

Flat LED lamps are used for work in hazardous areas IEC 60079-10-1 or Zones 21 and 22 of hazardous areas IEC 60079-10-2 (production halls and utility rooms), which are commonly found in the chemical, petrochemical and pharmaceutical industries, gas boiler houses, gas stations, offshore platforms, in the automotive and aerospace industries, and shipyards. They can be suspended, signal or built-in, depending on the area of ​​use.

In particular, the popularity of using led-luminaires lies in their high energy efficiency, their robust construction withstands careless handling and vibration, and their extremely long service life, which remarkably saves the cost of replacing fixtures and their repair. Despite their compact size, they offer a high light output, which together with the IP68 protection class makes them especially suitable for use in confined spaces, inside the machine of the enclosure, in silos, sewage treatment plants and other

Installation rules require special care, measures must be taken to prevent harm to workers, for example, protecting the lamp power line with a separate RCD.

The LED of the carrier board is installed inside a transparent, impact-resistant polycarbonate protective shell of a white coating that acts as a reflector.

Benefits

• High efficiency 6, 8, 12, 15 and 24 watts can replace the more expensive and dangerous metal halide lamps
• Extremely long service life
• These are energy saving devices.
• no need to regularly buy new diodes
• Wide voltage range: 85-264 V AC, 12-24 V DC or 24-50 V AC / DC with a frequency of 50-60 Hz
• Durable polycarbonate coating
• Use plants with increased risk of explosions, fire, gas leaks, etc.
• High degree of protection IP68

Luminaires with fluorescent lamps

Another type of explosion-proof fixtures is industrial luminescent models.

These models are also equipped with a hardened case, which is made of metal alloys that are resistant to high temperature or the effects of water and steam. These are titanium, aluminum, alloy steel, nickel and others.

Fluorescent tubes are very prone to explosion due to the high pressure inside the bulb. They are additionally protected by impact-resistant glass, which is hermetically fixed to the housing.

In the LFX series, explosion-proof fluorescent lamps are designed for use in almost any hazardous location. Typical applications for these two and four lamp explosion-proof lamps: chemical plants, drilling rigs, factories, lighting of construction sites, industrial premises.

Fluorescent lamps have special technical characteristics in comparison with other models:

1. Light weight, resistant to corrosion, the case is most often made of an alloy of copper and aluminum
2. Heavy aluminum cover to maximize light reflections
3. Tempered borosilicate glass provides maximum protection against heat and steam
4. Seals are rubberized gaskets and rings resistant to acids and fire
5. These luminaires are very high security.

Marking

• UL (2 and 4 luxar lamps)
• 1598a - floodlights that are used in conditions of work at sea (tanker), these are waterproof models;
• 844 - in dangerous places
• cUL - closed or open series

Lamps can be street (rku) or for outdoor lighting. They must be not only explosion-proof, but also resistant to temperature extremes, completely tight, and also equipped with a motion sensor (this requires a quality certificate). Installation is carried out using a special clamp NB.

What lights can not be used in hazardous areas:

1. High pressure sodium lamps (days);
2. Decorative devices without special protective elements: grilles, metal casing, durable glass.
