1. Introduction
1.1. Intended use
The subject of this manual is an explosion-proof LED luminaire of an OREX 1 type, which is
characterised by high luminous flux and power of up to 160 W. It is a compact light source with ultra-
bright LEDs installed for high intensity of lighting from high heights. LEDs are enclosed in a corrosion-
resistant housing made of high-quality aluminium. LEDs do not emit UV light.
1.2. Functional properties
OREX 1 luminaire is intended for lighting:
−industrial facilities and areas classified to the zones 1, 2, 21 and 22 of explosion hazard of dust,
gases, vapours and vapours of flammable liquids,
−auxiliary rooms with high dust concentration and a possibility of the occurrence of water splashes
that is: boiler rooms, pumping wells with observation wells, washrooms, garages, sheds, ware-
houses in open and restricted areas,
−process lines for the chemical, petroleum, gas, wood-working, loose mining, construction and
foodstuff material processing industry.
2. Design
The OREX 1 luminaire consists of the following components:
−tempered glass pane,
−body - powder-coated aluminium alloy,
−back cover - powder-coated aluminium alloy,
−compression ring - powder-coated aluminium alloy,
−cable gland 2 x M20x1.5 (2 x M25x1.5 as an option),
−terminals 2.5mm2
−power supply unit,
−clamp,
−optional DALI control.
