Abstract
An aircraft navigation light comprises a support portion, a light source comprising at least one green LED, the light source being arranged on the support portion, an optical element arranged over the light source for shaping an aircraft navigation light output, and a red light filter. A method of producing an aircraft navigation light comprises the steps of providing a support portion, providing a light source comprising at least one green LED, arranging the light source on the support portion, molding an optical element over the light source, and molding a red light filter over the optical element.
Claims20
An aircraft navigation light, comprising:
- a support portion;
- a light source comprising at least one green LED and at least one red LED, the light source being arranged on the support portion;
- an optical element arranged over the light source for shaping an aircraft navigation light output;
- a switching circuit configured to either supply the at least one green LED or the at least one red LED with electricity;
- an orientation sensor configured to detect an orientation of the aircraft navigation light and provide an orientation indication to the switching circuit;
- and
- a red light filter.
An aircraft navigation light, comprising:
- a support portion;
- a light source comprising at least one green LED and at least one red LED, the light source being arranged on the support portion;
- an optical element arranged over the light source for shaping an aircraft navigation light output;
- a switching circuit configured to either supply the at least one green LED or the at least one red LED with electricity on the basis of a color selection signal;
- and
- a red light filter;
- wherein the aircraft navigation light is configured to be usable as left forward navigation light, which emits red light, and as a right forward navigation light, which emits green light,
- wherein the luminous flux of the aircraft navigation light, when employed as a left forward navigation light and when the at least one red LED is supplied with a predefined electrical current, is between 80% and 120% of the luminous flux of the aircraft navigation light, when employed as a right forward navigation light and when the at least one green LED is supplied with the said predefined electrical current.
