A method for controlling an aircraft having a plurality of LEDs, light so as to emit a desired light intensity includes the steps of providing a reference LED located within or outside of the aircraft light, providing thermal conditions resulting in a thermal stress for the reference LED similar to the maximum thermal stress, and observing the reference LED by means of an optical sensor for monitoring the optical aging behavior of the reference LED throughout its lifetime. The desired light intensity of the aircraft light is achieved by controlling the plurality of LEDs in accordance with the monitored aging behavior of the reference LED.

Method for controlling an aircraft light

An air outlet device for a vehicle, especially for an aircraft, comprises a nozzle body with an air intake opening and an air outlet opening. The air outlet device further comprises a holding element formed with an accommodating opening having the nozzle body supported therein for rotation about a longitudinal axis extending through the air intake opening and the air outlet opening, and a valve body arranged coaxially within the nozzle body and guided by the holding element. Upon rotation of the nozzle body, the valve body can be displaced in the nozzle body between a closing position for blocking the air outlet opening and a maximum opening position for clearing the air outlet opening to the maximum extent. The valve body is of a hollow configuration.

Air outlet device for a vehicle, especially for an airplane

The air outlet device () for the interior of a vehicle, particularly for being arranged above a seat of a vehicle such as, e.g., an airplane, a bus or the like, is provided with an air outlet element () comprising at least one air inlet opening () and an air outlet opening (). Further, the air outlet device () comprises a slide element () for blocking and unblocking the at least one air inlet opening () and an actuating element () for moving the slide element (), which is arranged at the air outlet opening () and comprises a collar. The actuating element () is supported so as to be pivotable about a longitudinal axis () of the collar. When the actuating element () is rotated, the slide element () is movable along a curved path for blocking and unblocking.
