Abstract: A sensing type lighting device includes a lighting main body, a sensing element, and an electromagnetic wireless communication module. The lighting main body includes a controlling circuit and a light source set. The sensing element and the electromagnetic wireless communication module are disposed within the lighting main body. A controlling method for a sensing type lighting group includes the following steps. Firstly, a first lighting device with a first sensing element and a first electromagnetic wireless communication module is provided. Then, a second lighting device with a second electromagnetic wireless communication module is provided. According to an environmental sensing result of the first sensing element, a communication channel between the first and second electromagnetic wireless communication modules is established. Consequently, a light intensity of the first lighting device and/or the second lighting device is correspondingly controlled.
