Aircraft light for emitting light in a desired spatial angular region and with a desired light distribution

摘要

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.

1. Aircraft light for emitting light in a desired spatial angular region and with a desired light distribution, comprising
a reflector (16) having an upper reflector portion (20) and a lower reflector portion (22), both reflector portions (20,22) being symmetrical to a plane (18), with the upper and lower reflector portions (20,22) being arranged on opposite sides of the plane (18), first LEDs (24) facing away from the reflector (16) for emitting light directly into the desired spatial angular region, wherein the first LEDs (24) are linearly arranged side-by-side within the plane (18), and second LEDs (26) facing towards the reflector (16) for emitting light to be reflected by the reflector (16) into the desired spatial angular region, wherein the second LEDs (26) are linearly arranged side-by-side within the plane (18) facing away from the first LEDs (24), wherein each of the first and second LEDs (24,26) emit light into a spatial angular region (32) symmetrical to the plane (18) with the spatial angular region (32) divided into a first subregion (34) closest to the plane (18), a second subregion farthest away from the plane (18), and a third subregion (38) arranged between the first and second subregions (34,36), and wherein each of the upper and lower portions (20,22) comprises first, second, and third reflective surfaces (40,42,44) associated to the first, second, and third angular subregions (34,36,38) of the light emitted by the first and second LEDs (24,26), with the first reflective surface (40) being convexly shaped, the second reflective surface (42) being substantially flat, and the third reflective surface (44) being partially parabolically shaped.
