1、 Classified by explosion-proof type

1. Explosion proof lampThis type of lighting fixture encloses all components that may ignite explosive gas mixtures in a single enclosure, which can withstand the explosive pressure of the internal explosive gas mixture and prevent the internal explosion from spreading to the surrounding explosive mixture. The principle is to use metal gaps to prevent the spread of explosive flames and cool the temperature of explosive products, achieving flame extinction and cooling, and suppressing the spread of explosions. Explosion proof lamps are the most common type of industrial lighting.
2. Increased safety explosion-proof lampThis type of lighting fixture does not generate arcs or sparks under normal operating conditions, and additional measures are taken to improve its safety and prevent the possibility of dangerous temperatures, arcs, and sparks in its internal and external components. Further protective measures are taken in the structure of the increased safety explosion-proof lamp to improve the reliability and safety performance of the equipment.
3. Positive pressure explosion-proof lampThis type of lighting fixture limits the entry of flammable mixtures into the interior of the device casing by maintaining the pressure of the protective gas inside the casing higher than the surrounding explosion-proof environment pressure. At the same time, it can also remove flammable gases that enter the casing when the equipment is not under positive pressure, preventing the formation of flammable mixtures inside the casing.
4. Non sparking explosion-proof lampThis type of lighting fixture takes measures in the design and manufacturing process to ensure that under normal operation and specified fault conditions, it will not produce arcs, sparks, or high-temperature surfaces that can ignite explosive gas mixtures.
5. Dust explosion-proof lampThis type of lamp is mainly used in environments with combustible dust, and special design and manufacturing measures are taken to prevent dust from accumulating inside the lamp and causing explosions.

2、 Classified by light source

1. Explosion proof incandescent lampExplosion proof lamps using incandescent light sources typically have high brightness and low color temperature.
2. Explosion proof high-pressure mercury lampExplosion proof lamps using high-pressure mercury vapor as a light source have high brightness and long service life.
3. Explosion proof low-voltage fluorescent lampExplosion proof lamps using low-voltage fluorescent light sources typically have lower power consumption and higher light efficiency.
4. Mixed light source lampExplosion proof lighting fixtures that combine multiple light sources can adjust brightness and color temperature as needed.

3、 Classified by usage method

1. Fixed explosion-proof lampExplosion proof lamps that are installed in fixed positions and cannot be moved. Usually used in places that require continuous lighting.
2. Removable explosion-proof lampExplosion proof lighting fixtures that can be easily moved and used in different locations. Usually used for temporary lighting or places that require flexible lighting.
3. Portable explosion-proof lampHandheld or portable explosion-proof lighting fixtures are typically used in places that require quick response or mobile lighting.

4、 Classified by type of electric shock protection

1. Class I explosion-proof lampOn the basis of basic insulation, connect easily accessible conductive components that are not charged during normal operation to the protective grounding conductor in the fixed circuit.
2. Class II explosion-proof lampUsing double insulation or reinforced insulation as safety protection measures, without grounding protection.
3. Class III explosion-proof lampUse a safe voltage with an effective value not exceeding 50V, and ensure that no voltage higher than this value is generated.

In addition, explosion-proof lamps can also be classified based on factors such as the protection level of the casing and the material of the supporting surface. When selecting explosion-proof lamps, it is necessary to choose according to specific usage environments and requirements to ensure that they can meet lighting needs and have sufficient safety performance.
