Abstract
An exterior aircraft light comprises: a base structure; at least one light source for emitting light providing a preliminary light output, wherein the at least one light source is arranged on the base structure; and a shutter arrangement for forming a light output of the exterior aircraft light by partially blocking the preliminary light output. The shutter arrangement is coupled to the base structure via a pivoting mechanism. When arranged in different pivoting positions, the shutter arrangement blocks different portions of the preliminary light output.
Claims20
An exterior aircraft light, comprising:
- a base structure;
- at least one light source for emitting light providing a preliminary light output, wherein the at least one light source is arranged on the base structure;
- and
- a shutter arrangement for forming a light output of the exterior aircraft light by partially blocking the preliminary light output, the shutter arrangement coupled to the base structure via a pivoting mechanism and comprising:
- a first pair of lateral connecting portions disposed on opposing sides of the base structure,
- a first arcuate shutter element extending between the first pair of lateral connection portions,
- a second pair of lateral connecting portions disposed on opposing sides of the base structure,
- a second arcuate shutter element extending between the second pair of lateral connection portions,
- wherein each lateral connecting portion of each of the first pair of lateral connecting portions and the second pair of lateral connecting portions defines a hole, and wherein each hole is disposed with respect to the base such that a common axis extends through a center of each hole such that the first arcuate shutter and the second arcuate shutter are configured to rotate about the common axis;
- wherein the shutter arrangement is configured to block different portions of the preliminary light output for different pivoting positions of the shutter arrangement.
A method of manufacturing an exterior aircraft light, comprising:
- arranging at least one light source on a base structure for providing a preliminary light output from light emitted by the at least one light source in operation;
- coupling a first arcuate shutter element to the base structure via a pivoting mechanism configured to pivot about an axis;
- coupling a second arcuate shutter element to the base structure via the pivoting mechanism configured to pivot about the axis;
- and
- bringing the shutter arrangement into an operating position relative to the base structure via the pivoting mechanism, with the shutter arrangement blocking a portion of the preliminary light output in operation.
