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.

Abstract: Disclosed is a glide-angle light for approach guidance of aircraft, comprising a housing with a light outlet opening in which a light channel with an optical axis is arranged, along which a light source for production of a light beam, a colored filter for splitting the light beam into a filtered beam component and an unfiltered beam component and a lens arrangement for focused emission of the light beam through the light outlet opening are arranged. Only a single light channel is arranged in the housing so that the glide-angle lights according to the invention can be produced at considerably less cost.
