Abstract
A helicopter search light comprises: a lighting arrangement, having at least one light source, the lighting arrangement having an adjustable light output; a light detector, which is configured for detecting light emitted by the at least one light source and reflected by the ground and/or at least one item on the ground and for providing a detection signal which is correlated to an amount of light detected; and a control unit which is configured for controlling the adjustable light output of the lighting arrangement of the helicopter search light depending on the detection signal provided by the light detector.
Claims15
A helicopter search light (1) comprising
- a lighting arrangement (2), having at least one light source (10, 20), the lighting arrangement having an adjustable light output;
- a light detector (30), which is configured for detecting light emitted by the at least one light source (10, 20) and reflected by the ground (200) and/or at least one item on the ground (200) and for providing a detection signal which is correlated to an amount of light detected;
- and
- a control unit (40) which is configured for controlling the adjustable light output of the lighting arrangement of the helicopter search light depending on the detection signal provided by the light detector (30).
A method of adjusting a light output of a helicopter search light, with the helicopter search light having a lighting arrangement (2), comprising at least one light source (10, 20) and having an adjustable light output, wherein the method includes:
- emitting light from the lighting arrangement of the helicopter search light,
- detecting light reflected by the ground (200) and/or an item on the ground (200) and providing a detection signal which is correlated to an amount of light detected;
- and
- controlling the adjustable light output of the lighting arrangement of the helicopter search light depending on the detection signal.
