LED Explosion Proof Lighting
Explosion proof lighting or hazardous location luminaires are used under environment where flammable gases or combustible dusts exist. These specialized lights must be tested and approved by strict regulations in different regions.
NJZ Lighting, as the leading manufacturer for hazardous location luminaires, is now manufacturing and supplying a complementary line of explosion-proof lights.
Note:
In North American regions, UL844 is the officially approved standard for these explosion-proof lights. Under UL844 regulations, different hazardous locations are defined by Class and Division systems like Class I Division 1 or Class I Division 2, Class II Division 1 or Class II Division 2.
While in European regions, ATEX or IECEx is the official certificate required for specialized lighting, different hazardous locations usually defined as different zones such as gas environment can be divided into zone 0 , zone 1 and zone 2, Dust environment can be divided into zone 20, zone 21 and zone 22.
Frequently Asked Questions
What is explosion proof lighting?
Explosion proof lighting or hazardous locations luminaires , are used in environments where flammable gases or combustible dusts exist. These special lights have to be tested and approved by strict regulations in different regions.
What are the applications for explosion-proof lighting?
Explosion-proof lighting can be used in various hazardous locations due to the presence of flammable vapors, gases, or combustible dusts as defined by the NEC. Examples include power plants, heavy industrials storage, facilities, paper mills, wastewater treatment plants, loading docks, platforms, shipyards, chemical and petrochemical processing facilities.
Explosion proof lighting is an equipment designed to prevent the ignition of flammable or explosive materials, gases, and vapors. Lighting is one of the most commonly used electrical devices in any type of workplace. The types of lighting can range from high power permanent fixtures to a common flashlight used for portable illumination. Every type of lighting used under a hazardous environment must be explosion-proof certified regardless of its size.
What is the difference between class 1 and class 2 locations?
Class I locations are those in which inflammable gases or vapors are or may be present in sufficient quantities to produce explosive or flammable mixtures. Class II locations are those that are hazardous because of the presence of combustible dust.
What are the advantages of LED explosion-proof lighting?
1.Higher efficiency: Lighting effect of ex-proof high sodium light is about 6lm/w while LED explosion-proof lights have reached 140lm/w, which provides better lighting effect, with less energy cost, less joint and wire, hence less potential risks.
2.Longer working time: The working time of LED Explosion-proof light in theory is more than 100,000 hours, and its actual working time in real-life application is 50,000 hours, which is working constantly for five years.
3.More Safe: the power driver of led explosion proof light is generally DC6-36V, prevent electric shock accident fundamentally, with no spark, less emitting heat, shock resistance, vibration resistance, led solid cold source have high explosion proof performance.
4.Environmental friendly: LEDs are made from non toxic materials, unlike fluorescent lighting that uses mercury that may pose a danger to the environment. LED’s are also recyclable.
