1. A lighting apparatus changeable between an illuminating state and a non-illuminating state comprising: a non-contact motion sensor arranged to sense a movement of a hand near the lighting apparatus; a checker arranged to check whether the lighting apparatus is in the illuminating state or in the non-illuminating state; and a controller arranged to control the lighting apparatus in the non-illuminating state in accordance with the checker to change from the non-illuminating state to the illuminating state in response to the movement of hand sensed by the non-contact motion sensor, and to control the lighting apparatus in the illuminating state in accordance with the checker to cause a change in illumination with the illuminating state kept in response to the same movement of hand sensed by the non-contact motion sensor as that in the non-illuminating state, wherein the controller is arranged to control the lighting apparatus in the illuminating state in different manner from that in the non-illuminating state according to the checker in response to the same movement of the hand sensed by the non-contact motion sensor.
