Patent ID: 8581164

Claim:
A light sensing system, comprising: a body, formed as stereoscopic, the body having a through hole penetrating a top of the body; a plurality of first light sensors, symmetrically disposed on the body and correspondingly generating a plurality of first sensing signals after sensing lights, wherein each of the first light sensors is faced to a sensing direction respectively by the shape of the body blocking; a base, arranged under the body; a plurality of second light sensors, disposed symmetrically on the base, the geometric center of the second light sensors corresponding to the geometric center of the through hole, and the second light sensors generating a plurality of second sensing signals correspondingly after sensing lights passing through the through hole directly, wherein the second sensing signals are related to a deviation angle of lights passing through the through hole; and a processing module, connecting to the first light sensors and the second light sensors, controlling the light sensing system towards to one of the sensing directions according to the first sensing signals, calculating the deviation angle according to a ratio of each pair of the second sensing signals disposed symmetrically, and further controlling the light sensing system according to the deviation angle.
