  • Patent number: 8789987
    Abstract: The invention relates to a base (1), in particular for light masts, comprising a housing (7) with a base surface (10) which can be filled with a medium. In order to ensure improved stability and to avoid additional grounding measures, an embodiment is chosen according to the invention in which the housing (7) is not electrically conductive and has a holding opening (21) for a mast (2) which is not round and is composed of non-conductive material. In this case, a mast (2) which is not round avoids lateral inclination of the mast (2), thus making it possible to ensure secure installation.

  • Patent number: 8651686
    Abstract: 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.

  • Patent number: 8632234
    Abstract: Pathway and landscape lights, in particular to devices, apparatus, systems and methods of using ground directed pathway and landscape lights with a single or perimeter spaced apart LED (light emitting diode) light sources on a disc mount, with or without an optical fiber arranged in a ring pattern about a perimeter edge of the mount. A light shade lens can have an upper end attached to the lower face of the disc mount, and a bottom end attached to a ground engaging post, so the light emitted from the mount is directed in a 360 degree outwardly expanding direction expanding outward on the ground surface where the ground engaging post is in the center of the 360 degree expanding illumination. A low voltage power source can be used. Alternatively, the light can be solar powered. The light forms uniform light beam emissions without shadow spots effects.
