A night light projector comprises a housing and a light emitter accommodated in the housing. The projector further comprises a rotator rotatable around the light emitter and a plastic film dome placed on the rotator and rotatable with the rotator. The plastic film dome covers the light emitter and allows partly transmitting and projecting the light from the light emitter. By means of the rotatable plastic film dome, the projector is able to project rotating spatial pattern into surrounding space.
