AERODROME LIGHTING DEVICE (VERSIONS) Russian patent published in 2014 - IPC F21V8/00 F21W111/06 

FIELD: electricity.

SUBSTANCE: light beam that left the first output face passes along the first channel and gets to the first input surface of the first window. Light beam that left the second output face passes along the second channel and gets to the second input surface of the second window. The light beam is discharged from the device via the first output surface of the first window and the second output surface of the second window. At the same time arrangement of the first window and second window in the form of an optical wedge with mutually perpendicular cylindrical surfaces or in the form of an optical wedge with a diffraction structure with rated relief applied onto the first input surface of the first window and the second input surface of the second window provides for formation of angular divergence of the light beam, which has asymmetric angular dimensions along the vertical line and horizontal line and change of its direction, providing for arrangement of the lower border of the light beam on the surface of a landing strip, and also provision of the specified direction of the axis of maximum brightness of light beam.

EFFECT: simplified design, reduced dimensions and weight of a device and improved technology for assembly into a landing strip surface.
