Abstract
A presence sensing method for a light comprises detecting a presence of a user by a sensing module having a first sensitivity while the light is off; turning on the light when identifying the presence of the user and keeping the light on for a delay time period which has a preset length; increasing a sensitivity of the sensing module to a second sensitivity after turning on the light; detecting actions of the user by the sensing module having the second sensitivity while the light is on; determining a length of a next delay time period based on the actions of the user during the previous delay time period immediately prior to the next delay time period; and keeping the light on for the next delay time period.
