FIELD OF APPLICATION: Thanks to the construction principles of the gasket, the closing system and the diffuser our LED fixtures ensure a high grade of protection (IP66) against dust, contamination and water permeation. (Optionally available in IP67). In accordance with their IP rating they can be widely used to illuminate spaces with dusty and humid environment. When using outdoors, the fittings should be protected against direct sunlight and adverse weather conditions. Under 0°C the application of venting cable gland is necessary, as well as the silicone gasket is recommended. TECHNICAL DESCRIPTION AND BENEFITS: n Housing available: in flame retardant glass fibre reinforced polyester , in light grey (RAL7035) colour (on request suitable for 850°C glow wire test, too). The glass fibre reinforced polyester has a very good temperature resistance and mechanical stability. Furthermore, it is a good electrical insulator resisting the impacts of several chemicals and weather conditions. Its stability of size and shape at changing temperatures is excellent. – Or in PC – injection moulded Polycarbonate in light grey (RAL7035) colour (suitable for 850°C glow wire test, too). Polycarbonate has high mechanical strength and high heat and shock resistance n Diffuser: Available in PC - injection moulded transparent Polycarbonate (high mechanical strength and high heat and shock resistance) or in Acrylic - injection moulded transparent PMMA (unique non-aging properties, high chemical resistance). Further benefits: - Extremely high lighting efficiency through high light permeability, unique on the market , up to 90% - An excellent light uniformity through well-balanced light dispersing (no shadows) - Elimination of the dazzling effect (no glare) - Keeping the usual, well known features of the diffuser such as chemical and heat resistance, mechanical features, UV stabilization etc. - Universal width (no single and twin) and slim shape simplifies the light calculation . n The gasket between the diffuser and housing is available in two versions: - Injected silicone-based endless foam - Non-aging PU (polyurethane) endless foam n Fixing the diffuser to the body: With tamper-proof (vandal-proof) stainless steel clips. n Gear tray (reflector): White powder coated steel sheet according to Zhaga standards or customised. n Electrical components: The adequate power supply is ensured with the electronic driver, that is built into the luminaire.
