In-grade light fixture with leveling and alignment mechanisms, installation features and anti-condensation valve
WO 2004083717 A3
Abstract
An in-grade light fixture (10), comprising a below grade light fixture having a light opening (15) substantially at grade level. An optical chamber (60) is arranged within the light fixture housing (16) and holding a light source generating light that passes through the light opening. A faceplate mechanism (11) mounted over the light opening (15) and to the optical chamber (60), and is held in place by mounting screws. The faceplate mechanism (11) is at least partially rotatable over the light opening (15) so that the location of said mounting screws can be adjusted around the light opening. An adjustment mechanism is included to adjust the height and angle of the faceplate mechanism (11) to match the height and angle of the surrounding grade level and angle. A holding mechanism can also be included for holding the light fixture housing at the desired height within a hole prior to being buried. An anti-condensation valve (120) can also be included on the optical chamber.
