Abstract: A light sensor for sensing an illumination of a partial area is disclosed. The light sensor includes a first case, a second case, a first light absorption layer and at least one sensing module. The first case includes at least one hole. The at least one hole includes an axis. The second case is fastened to the first case, and a containing space is formed between the first case and the second case. The first light absorption layer is located on the first case. The at least one sensing module is located in the containing space, and the position of the at least one sensing module is located on the axis of the hole. The at least one sensing module is used for sensing the light from the partial area which passes through the hole so as to obtain the illumination of the partial area.
