Abstract
An aircraft light for emitting light in a desired spatial angular region and with a desired light distribution, comprises a reflector having an upper reflector portion and a lower reflector portion both being symmetrical to a plane. A first row of LEDs are face away from the reflector. A second row of LEDs face towards the reflector. Each of the upper and lower portions of the reflector comprises first, second, and third reflective surfaces with the first reflective surface being convexly shaped, the second reflective surface being substantially flat, and the third reflective surface being partially parabolically shaped.
