Abstract
An exterior aircraft light comprises at least one switchable illumination circuit. Each of the at least one switchable illumination circuits comprises at least one light source, a temperature detector configured for detecting the temperature of the at least one light source and providing a temperature signal, an electric switch for selectively switching power flow to the at least one light source on and off, and a control circuit which is coupled to the temperature detector and to the electric switch. The control circuit is configured for driving the electric switch based on the temperature signal provided by the temperature detector to repeatedly switch power flow to the at least one light source on and off.

An exterior aircraft light comprising at least one switchable illumination circuit, each of the at least one switchable illumination circuits comprising:
- at least one light source;
- a temperature detector configured for detecting the temperature of the at least one light source and providing a temperature signal;
- an electric switch for selectively switching power flow to the at least one light source on and off;
- a control circuit, coupled to the temperature detector and to the electric switch, wherein the control circuit is configured for driving the electric switch based on the temperature signal provided by the temperature detector to repeatedly switch power flow to the at least one light source on and off.
A method of operating an exterior aircraft light comprising at least one switchable illumination circuit, each of the at least one switchable illumination circuits comprising at least one light source, a temperature detector configured for detecting the temperature of the at least one light source, and an electric switch for selectively switching power flow to the at least one light source on and off,
- wherein the method includes for each of the at least one switchable illumination circuit:
- detecting the temperature of the at least one light source;
- and
- controlling the electric switch for repeatedly switching power flow to the at least one light source on and off based on the detected temperature of the at least one light source.
