Do your factory’s explosion-proof lighting bulbs use explosion-proof ones? In the minds of ordinary people, the common bulbs are incandescent lamps. And explosion-proof lamps have relatively few contacts, so what is explosion-proof lamp. The following article will give you the answer.
What is an explosion-proof lamp?
Explosion proof lamps refer to lighting equipment that can contain sparks that may ignite flammable and explosive gases in the atmosphere. Therefore, explosion-proof lighting does not refer to explosion-proof lighting equipment, but rather to the ability to prevent external explosions in hazardous locations.
Explosion proof lamps are usually installed in thick frames, which are usually made of sturdy materials such as steel or aluminum. The explosion-proof lighting fixtures are also equipped with durable lenses, which can withstand harsh working conditions. Prevent the occurrence of cracks, which can lead to leakage.
Explosion proof principle
Actually, explosion-proof lamps are not explosion-proof bulbs, they are still ordinary bulbs. No matter incandescent lamp, energy-saving lamp, Induction lamp or LED, they are all light sources. They themselves are not explosion-proof. Instead, an explosion-proof lamp housing was added to them, and the incoming line was connected using a threaded knob type. Explosion proof lamp type to prevent possible internal arcs, sparks, and high temperatures.
How Explosion Proof Lamps Work
Explosion proof lamps are a special type of lamp mainly used to provide lighting in hazardous areas to protect people’s safety. Its working principle is based on preventing the generation of sparks or static electricity, and avoiding the ignition of explosive mixtures.
When the explosion-proof lamp is working. The bulb will generate high-temperature current flowing through the filament, causing the filament to heat up. After the filament heats up, a high-temperature tungsten filament is produced. The heat of this tungsten wire will emit visible light.
However, when the light bulb is working, it is tightly connected to the electrical equipment. When electrical equipment malfunctions or is not operated properly, sparks or static electricity can be generated. These sparks or static electricity may ignite explosive mixtures, leading to the occurrence of explosion accidents.
To solve this problem, explosion-proof lamps use a special set of lamps to prevent the generation of sparks or static electricity. This group of lamps typically includes a light bulb with an explosion-proof cover and a special circuit board. There are many control circuits on the circuit board. Used to monitor the operation of light bulbs to prevent sparks or static electricity.
When the circuit board detects sparks or static electricity in the light bulb. It will immediately cut off the power supply to avoid igniting explosive mixtures. At the same time, the light bulb will also automatically extinguish to prevent possible explosion accidents.
Therefore, the working principle of explosion-proof lamps is to use special lighting fixtures and circuit boards. It is to prevent sparks or static electricity, thus protecting people’s safety.
Where are explosion proof lamps most often used?
Explosion proof lamps are a lighting tool specifically designed for explosive environments, and therefore are used in many industries and locations. The following are some commonly used explosion-proof lamp applications:
- Mine: Explosion proof lamps can provide safe lighting to avoid accidents caused by combustible dust and toxic gases in the mine.
- Flour processing plant: Explosion proof lamps can provide safe lighting to avoid explosion accidents caused by flour dust.
- Chemical plants: Explosion proof lamps can provide safe lighting to avoid explosion accidents caused by chemical substances.
- Oil depot: Explosion proof lights can provide safe lighting to avoid explosion accidents caused by oil and gas in the oil depot.
- Factory: Explosion proof lamps can provide safe lighting to avoid explosion accidents caused by machinery and equipment.
- Hospital: Explosion proof lamps can provide safe lighting to avoid explosion accidents caused by medical equipment.
- Fire Brigade: Explosion proof lamps can provide safe lighting to avoid explosion accidents caused by fire-fighting equipment.
In these places, explosion-proof lights can provide safe lighting. To avoid explosion accidents, explosion-proof lamps have been widely used in these places.
Choosing the Right Type of Explosion Proof Lamp
Choosing a suitable explosion-proof lamp requires considering many factors. The following are some important considerations:
- Explosion proof level: The explosion proof level of explosion-proof lamps is very important. Select explosion-proof lamps with corresponding explosion-proof levels based on the hazard level to ensure the safety of the lamps.
- Lamp type: Select the appropriate lamp type, such as straight or reflective lamps, based on the location and purpose of lighting provided as needed.
- Lamp size and shape: According to the required lighting location and purpose. Choose the appropriate size and shape of lighting fixtures to ensure their safe installation and normal operation.
- Electrical connection: The electrical connection of explosion-proof lamps is very important. Choose explosion-proof lights that are compatible with the electrical system and ensure secure connections.
- Lamp housing: In order to protect the internal light bulb, many explosion-proof lamps provide special housing. Choose the appropriate enclosure type based on the location and purpose of lighting provided as needed.
- Usage environment: Select appropriate explosion-proof grade and explosion-proof lamps that meet the requirements based on the usage environment and requirements of explosion-proof lamps. For example, explosion-proof lamps used in high-temperature environments need to choose different levels of explosion-proof rating.
Takeaway:Taking into account the above factors, it is very important to choose a suitable explosion-proof lamp. If you are unsure about the choice of explosion-proof lights, it is recommended to consult a professional or manufacturer.
