Claim 13:
14. A motion detection method comprising:
receiving a motion signal from a luminaire comprising a motion sensor, said motion signal being correlated with motion of objects in an environment of the motion sensor, wherein said luminaire being connectable to a light emitting element,
signal-processing the motion signal to obtain multiple motion components, a motion component being correlated with a direction and velocity of a motion in the environment,
cancelling in the motion components, two motion components that correspond to motions with opposite values to remove the contribution of the two motion components that correspond to motions with the opposite values,
detecting motion of objects in the environment from the motion components that are not cancelled,
controlling the light emitting element at least in dependency upon the motion sensor.
