Description
Luminaire recessed into the ground designed to use metal-halide lamps with adjustable spot optic. The product is used exclusively in the multiple-shape Light Up Walk professional system in combination with multiple frame and outer casing - both to be ordered separately. The body is made of cast aluminium and all the screws are made of stainless steel. Visual comfort is guaranteed by the a black steel antiglare screen. The optical assembly is closed at the top by a hardened sodium-lime glass (thickness 15 mm) with silicone gasket compressed by an AISI 304 stainless-steel frame. The optical assembly houses a hardened sodium-lime intermediate glass (thickness 4 mm) with white silk-screen printing. The lower section houses a decompression box for cascade wiring by 6-pole terminal block and double stainless-steel cable-clamp M24x1.5. This section is connected to the optical assembly through a nickel-plated brass cable clamp M15x1. This makes it easier to open the upper glass by eliminating negative pressure inside the optical assembly and the pump effect on the supply cable. The body-optical assembly is equipped with a locking system with two stainless-steel captive screws on which two extruded aluminium supports can slide. The locking system ensures positioning and anchoring of the optical assembly to the outer casing. The acrylic painting of the body-optical assembly and outer casing guarantees protection against UV rays and the external environment. The coupling of frame, glass, optical assembly and outer casing guarantees resistance to a static load of 5000 kg. Glass surface temperature does not exceed 80°C.
