Explosion-proof LED lighting fixture (protection level 1Ex) is used for general and emergency lighting highly explosive areas 1, 2 and fire risk classes; and also hazardous areas of zones 21, 22 e.g industrial areas as oil-refining, gas chemical, woodwork and other industries.

  • working rated voltage of AC 100...305V and DC 142...431V;
  • the input node is securely connected to the housing with the help of a steel threaded sleeve (passage insulator), which provides not only the strength of the structure but also the maintenance of the parameters of the threaded explosive gap throughout the service life;
  • there are modifications with power 40W that have emergency unit with battery for emergency mode at least 3 hours;
  • or request, lighting fixture can be with DIM driver - regulation of the intensity of the light flux by the method of dimming(1...10V DC) in the range 10...100%;
  • on request lighting fixture can be with DALI driver - intelligent digital control system, which allows automatic and semi-automatic control of the brightness and operation of a lighting fixture or group of fixtures;
  • explosion protection is increased because body’s heating temperature is reduced (LED block is mounted on special radiator, which disposes warm), it helps to use lighting fixture on hazardous manufactures;
  • high IP-requirements, shockproof;
  • weatherproof - long life cycle;
  • source of light - energy efficient LEDs (more than 50 000 hours of continuous work), ecological harmless, don't need special recycling (without mercury), instant light on/light off, stable to change of voltage, multiple on/off, high colour rendering; no harmful effect of low-frequencypulses, no UV radiation;
  • electric components and LEDs are from leading world manufacturers;
  • two cable glands make possible quick transit connection to power supply line.
Housing: aluminum alloy.
Light-transparent protective element: heat-resistant glass.
Protective grid (on request): steel wire.
Control gear:• driver Mean Well
• driver and emergency unit
• driver with DIM function (on request)
• DALI driver (on request)
Cable gland: 1 or 2pcs., plug (3) for modifications -Х11, -Х12, -Х21, -Х22.
Source of light: LEDs Seoul Semiconductor.

Delivery set: Lighting fixture with LEDs, on request - mounting knot.
