Explosionproof LED lighting fixtures are intended for general lighting of explosion hazardous areas of all classes according to the explosion protection marking.
- LED light sources allows reducing maintenance costs. Service life of LEDs is around 100,000 h.
- LED light source consumes by ten times energy less than incandescent lamp with the similar luminous flux. Lighting fix ture eﬃciency approaches 100 % which also has an impact for energy saving.
- Corrosion-resistant materials with special coating ensure long service life.
- Lighting fixture is resistant to mechanical and vibration impact and has tamper resistant design.
- Absence of mercury in lighting fixture elements provides simple and environmentally safe disposal of lighting fixture.
- Instantaneous switching on of the lighting fixture and its output to the set power, high luminous flux, proximity of the color temperature to natural sunlight, low glare, high color rendering index as well as the absence of stroboscopic eﬀect (flickering) make the lighting fixtures indispensable at production site.
The lighting fixture consist of round body made from aluminum alloy. The light-transmission element is screwed into the enclosure.
The lighting fixture is divided into three compartments: input compartment, power supply compartment and lighting equipment compartment. The power supply compartment is filled with compound.
