Abstract:
1. An LED landing light arrangement for an aircraft, said LED landing light arrangement comprising a plurality of LED light sources for arrangement on an aircraft, primarily on the wing roots, on the front edges of the wings and/or on the landing gears, said LED light sources are operative to generate, relative to a central axis of the aircraft, a fixed beam of light having light distribution ahead of the aircraft that is spread substantially in a Y-shaped configuration in an obliquely downward direction, said light distribution comprising two converging lateral regions arranged laterally ahead of the aircraft, and a central region running from said converging lateral regions along an extension of said central axis and oriented in a direction away from the aircraft; wherein said light distribution spread substantially in a Y-shape extends across a first lateral-angle region (2 times β) between 60° and 100° centered about the central axis of the aircraft, extending a distance from the aircraft of at least 15 m up to maximally 150 m and across a symmetric second lateral-angle region (2 times α) between 0° and 20° centered about the central axis of the aircraft extending a distance from the aircraft of 30 m up to maximally 1000 m.
