Technical description:
Luminaire recessed into the ground with die-cast aluminium body and outer casing; stainless-steel frame and screws; black painted conical screen. It is designed to use halogen lamps with dichroic reflector and adjustable optic. The outer casing for installation can be ordered separately from the optical assembly. The optical assembly is closed at the top by a hardened sodium-lime glass (thickness 12 mm) with silicone gasket compressed by an AISI 304 stainless-steel frame. The lower section houses a decompression box for wiring by two terminal blocks and a stainless-steel cable-clamp PG11. This section is connected to the optical assembly through a nickel-plated brass cable clamp M11x1. 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 aluminium plates 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 70°C.
Installation:
Recessed into the ground by means of an outer casing. The upper rim of the installed outer casing should protrude out of the pavement by 1mm MAX. The outer casing has an upper diameter of 124 mm, a lower diameter of 236 mm, and is 118 mm high.
Colour:
