Abstract
Abstract Luminaire for street lighting comprises an inverted bowl-shaped casing having a flat leveling pad formed on its top surface and having a slipfitter socket at its rear end arranged with its axis parallel to the plane of the leveling pad. The rim of the casing is at an acute angle to the leveling pad. Leveling screws on the slipfitter enable the luminaire casing to be tilted at the correct angle by adjusting the screws with reference to a spirit level placed on the leveling pad.
