Abstract
A lighting device and a method for adjusting the sensing region thereof are provided. The lighting device includes a sensing device and an illumination unit. The sensing device is configure to detect whether an object is located at a first manipulating region or a second manipulating region so as to correspondingly emit a control signal, in which the first manipulating region and the second manipulating region are not overlapped by each other and are disposed in the sensing region along a sensing direction of the sensing device. The sensing device adjusts a shortest distance between the sensing region and the sensing device and a sensing range of the sensing region according to a first adjustment signal and a second adjustment signal. The illumination unit is coupled to the sensing device and adjusts the optical characteristic according to the control signal.
