1. A luminaire comprising a motion detector, the motion detector comprising:
a motion sensor interface configured to receive a motion signal from a motion sensor, said motion signal being correlated with motion of objects in an environment of the motion sensor,
a processor system configured to:
signal-process the motion signal to obtain multiple motion components, a motion component being correlated with a direction and velocity of a motion in the environment,
cancel 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,
detect motion of objects in the environment from the motion components that are not cancelled,
wherein the luminaire being connectable to a light-emitting element and being configured to control the light-emitting element at least in dependency upon the motion detector.
