Ex Lighting Fixtures

Ex-proof lighting fixtures are designed to be used in environments with explosion risk. These environments are generally petrochemical industry, oil and natural gas production facilities, mines, refineries, chemical laboratories, and similar places.

Ex Lighting Fixtures

Ex-proof lighting fixtures are designed to be used in environments with explosion risk. These environments are typically petrochemical industry, oil and natural gas production facilities, mines, refineries, chemical laboratories, and similar locations. The lighting fixtures used in these environments are made of explosion-resistant materials and have special design features.

Ex-proof lighting fixtures can be designed in different ways depending on the source of the explosion risk and the classification of the environment. The classification of the environment is a system that determines how widespread and intense the explosive substances are. This system is defined by IEC (International Electrotechnical Commission).

Types of Ex-proof lighting fixtures especially vary in terms of lighting sources and design features. Some examples:

  • LED Ex-proof fixtures: LED lighting sources are popular due to lower energy consumption and longer lifespan compared to other lighting sources. Additionally, LED fixtures have a structure that is not affected by variables such as temperature and humidity.
  • Halogen Ex-proof fixtures: Halogen lighting sources are preferred because of high color quality and high light output. However, they have higher energy consumption compared to other lighting sources.
  • Ceiling-mounted Ex-proof fixtures: Fixtures mounted on the ceiling are used to illuminate a wide area. These fixtures are more popular in areas with low ceilings and generally contain fluorescent lamps.
  • Suspended type Ex-proof fixtures: Suspended fixtures are used in areas with higher ceilings. These fixtures generally contain projector lamps and provide a wider lighting area.
  • Emergency Ex-proof fixtures: Ex-proof fixtures used in emergencies operate with an internal battery and can continue to work even in situations such as power outage.

Classification of Ex Alighting Fixtures

Ex fixtures are special fixtures used in explosive environments. The classification of these fixtures is made according to their usage areas and the hazard level of the explosive environment.

Ex fixtures are classified according to explosion resistance classes defined by the IEC 60079-0 standard. According to this standard, Ex fixtures are classified as follows:

  1. Explosion Resistance Class: Ex d This class covers fixtures with a closed structure that provides protection against explosions. These fixtures are used in areas with dense explosive gases and vapors.
  2. Explosion Resistance Class: Ex e This class covers open or closed fixtures with protection class IP54 and below. These fixtures are used in areas where explosive dust is present.
  3. Explosion Resistance Class: Ex n This class covers fixtures used in areas with low explosion risk. These fixtures are generally used where explosive gases and vapors are not very dense, and the explosion risk is low.
  4. Explosion Resistance Class: Ex p This class is valid for pressurized vessels and fixtures used in areas densely populated with explosive gases and vapors.
  5. Explosion Resistance Class: Ex i This class covers fixtures used in explosive environments that use limited amounts of energy. These fixtures are used in low voltage devices.
