What’s explosion proof lights ?
Explosion proof lights are a type of lighting equipment specially designed for use in hazardous environments, capable of being used safely in flammable and explosive gases, vapors or dust environments. Its features include explosion-proof, dust-proof, water-proof and corrosion-resistant. Explosion-proof lamps are usually designed with special materials and structures to ensure that they do not cause sparks or generate high temperatures in hazardous environments.
Продуктите за защита от експлозия са подходящи за IIA, IIB, IIC експлозивна газова среда и различни запалими и експлозивни места, използвани главно в железопътния транспорт, електроенергетиката, металургията, нефта, нефтохимията, химическата промишленост, стоманата, авиацията, кораба и всяко ефективно осветление в заводи, гари, големи съоръжения, места и други места.
Explosion proof lights are divided by shape: round explosion proof lights (explosion proof high bay light), square explosion proof lights (explosion proof flood light), linear explosion proof lights, explosion proof emergency exit lights, explosion proof mobile working lights, explosion proof street lights.

General knowledge of explosion proof lights
1. explosion proof principle of explosion proof electrical equipment
explosion proof type | explosion proof principle | Приложение |
Enhanced safety type “e” | Electrical equipment that does not generate arcs or sparks under normal operating conditions is protected by additional measures to increase its safety and reliability and to prevent the generation of dangerous temperatures, arcs and sparks from its internal and external components. | explosion proof lighting, explosion proof motors, explosion proof junction boxes,Ex plugs and sockets, Ex flexible connection hoses |
Flameproof “d” | An enclosure for electrical equipment that can withstand the explosion of a combustible mixture that has entered the interior of the enclosure without damage, and that will not ignite an external explosive atmosphere formed by one or more gases or vapors through any joints or structural holes in the enclosure. | explosion proof distribution box, explosion proof button, explosion proof operation column,explosion proof circuit breaker, explosion proof lamp, explosion proof motor. |
Positive pressure type “p” | Positive pressure type “p” reduces the concentration of the explosive mixture inside to below the explosion limit by keeping the pressure of the protective gas inside higher than that of the surrounding area to avoid the entry of the explosive mixture into the enclosure or the passage of sufficient protective gas throughthe enclosure so that the concentration of the explosive mixture inside is reduced below the explosion limit. | explosion proof analyzer cabin, explosion proof power distribution and control unit |
Intrinsically safe “i” | Under the specified test conditions, the electrical sparks and thermal effects generated by the circuits inside the equipment in normal operation or under the specified fault conditions shall not ignite the specified explosive mixture.Electrical equipment that cannot ignite the specified explosive gases or vapors under the specified test conditions or under the specified fault conditions. | explosion proof communication equipment, explosion proof sensors, explosion proof measurement and control equipment. |
Cast-in type “m” | The part of the arc, spark or high temperature that may produce ignition of an explosive mixture is cast so that it cannot ignite the surrounding explosive gas mixture. | explosion proof transformers |
2. Relationship between the classification, ratings of gases or vapors in the premises and the types, classes of equipment allowed to be used
Gases/vapors/classification/ratings in premises | Permitted Equipment Classes |
IIA(e.g. propane, pentane, benzene, gasoline, ethanol, acetaldehyde, acetone, methylamine, etc.) | IIA,IIB or IIC |
IIB(e.g. ethylene, dimethyl ether, coke oven gas, etc.) | IIB or IIC |
IIC(e.g.: hydrogen, acetylene and carbon disulfide) | IIC |
3. Relationship between temperature groups, equipment surface temperatures and ignition temperatures of flammable gases or vapors
Temperature group | Ignition temperature of gas or vapor ℃ | Maximum surface temperature of electrical equipment ℃ |
T1 | T>450 | 450 |
T2 | 450≥T>300 | 300 |
T3 | 300≥T>200 | 200 |
T4 | 200≥T>135 | 135 |
T5 | 135≥T>100 | 100 |
T6 | 100≥T>85 | 85 |
Explosion proof light classification:
1. According to the shape is divided into: round explosion proof light (explosion proof high bay light), square explosion proof light (explosion proof flood light), long explosion proof lights, explosion proof emergency exit lights, explosion proof moving lights, explosion proof street lights.
2. According to the explosion proof type is divided into explosion proof, increased safety, positive pressure, non-sparking type and dust explosion proof a total of five major types, but also by the other explosion proof type and the above explosion proof type or combination of various types of composite and special type.
