| 20090279287 | ELEVATED LIGHT WITH A SAFETY POWER CUT-OFF SWITCH - An elevated light apparatus for an airport runway light system comprises a mast mounted to a base plate, which is attached to a base-cup. The mast can be designed with a hollow configuration to allow internal electrical connection between a light source in a light assembly and an isolation transformer in the base-cup. The mast can include a frangible break joint that cleanly separates the mast from the base plate. A safety power cut-off switch can be fixed into the base plate on the base-cup. The power cut-off switch can be positioned in the frangible break joint so that a switch button can be held closed by a breakaway portion of the frangible break joint. In the event of mast breakage, the switch button can be released to open electrical circuits for quick disconnection of the electrical connection. | 11-12-2009 |
| 20090323320 | SYSTEM AND METHOD FOR COMMUNICATING AN AIRCRAFT'S INTENDED PATH TO THE RUNWAY TO DIRECT THE AIRCRAFT ALONG THE RUNWAY - In a method of dynamically guiding an aircraft the intended path of the aircraft may be broadcast along at least one of a runway and a taxiway. The broadcasted intended path of the aircraft along the at least one runway and taxiway may be received. The lighting characteristics of an airport lighting device along the at least one runway and taxiway may be dynamically changed to dynamically guide the aircraft along the broadcasted and received intended path of the at least one runway and taxiway. | 12-31-2009 |
| 20100008073 | AIRPORT INSET LIGHTS WITH A FLOW PATH FOR PRESSURE EQUALIZATION - An airport inset light for an airport runway light system comprises a light fixture incorporating a light source that is covered with a lens. A flow path can be provided in the light fixture such that air can pass unrestrictedly between an exterior environment and an interior space of the light fixture. The flow path can be covered or filled with a hydrophobic filter material, which allows for the light fixture interior to exchange air with its exterior environment. Such a flow path can create pressure equalization between the exterior environment and the light fixture interior to prevent the formation of a vacuum in the light fixture interior. Hence, it can eliminate the possibility of water entering the interior of the light source due to pressure differential between the environment and the light source interior. | 01-14-2010 |
| 20100188842 | Illumination Device for Paved Floor - An illumination device for illuminating a paved floor comprising a container, which comprises a box creating a cavity therein and a first frame, integrally connected to the upper rim of the box; an illumination set comprising at least one light source (e.g. LED), where the illumination set is installed inside the container, where at least one light source enables illumination of the illumination device; a cover, which is adapted to be seated within the first frame, where the cover enables light from the illumination set to be transferred therethrough; a second frame, enabling to hold the cover between the first and the second frame; and at least two fastening means enabling to fasten the second frame to the first frame to hold the cover therebetween. The illumination device may be configured to be installed in the paved floor as one of the floor's tiles. | 07-29-2010 |
| 20120218742 | LIGHTING UNIT FOR LIGHTING AIRFIELDS - The invention relates to a lighting unit for lighting airfields on an airport, in particular for delivering signals to an airplane. It comprises a light source, which has at least one light-emitting diode for generating light to be emitted, electrical components for supplying and actuating the light source, optical components for influencing the light generated by the light source, and an outer housing for receiving the light source and the electrical and optical components, which has a light exit opening through which light influenced by the optical components exits. According to the invention, the light source is arranged with the electrical and optical components in a cassette module closed in a gas-tight manner. Said module is integrated in the outer housing, wherein the outer housing is likewise closed in a gas-tight manner, so that the components disposed in the cassette module have double sealing protection. | 08-30-2012 |
| 20150077979 | Road Surface Lighting Apparatus - A road surface lighting apparatus is used illuminate a large surface area of a road such as a highway or interstate. The apparatus includes a traffic barrier, a wide band lamp, solar panels, auxiliary electrical leads, and a horizontal conduit. The traffic barrier is used to situate and position the wide band lamp along the length of the road. The wide band lamp is designed to emit light in the form of an ellipsoid arc. The solar panels provide renewable electrical power to the wide band lamp, and the auxiliary electrical leads provide electrical power to the wide band lamp from an external source. The horizontal conduit is used to house the electrical connections from the solar panels and/or the auxiliary electrical leads to the wide band lamp. | 03-19-2015 |
| 20150369469 | In-Grade and Under-Water Light Fixture Housing Made of Ceramic Material - A housing, particularly for a Light Emitting Diode (LED) or otherwise lamped in-grade or under-water light fixture, is made of ceramic material, such that the housing is not affected by corrosive substances commonly found in soil, masonry, and water that surrounds the installed fixture. The ceramic housing establishes a good conductor of heat and does not conduct electricity. A lens and lens frame are secured to the housing and provisions are made to assure the integrity of the overall assembly even when the light fixture is employed in damp and wet environments and/or where heavy loads can bear down on the lens, such as when the light fixture is embedded in a paved roadway and subjected to vehicular traffic rolling there over. | 12-24-2015 |
