Abstract: A lighting device may include a light illumination portion, a light control portion, a sensing portion, a main control module, and a first connector. The light illumination portion may generate and illuminate light. The light control portion may control power applied to the light illumination portion. The sensing portion may include a sensor that senses an environment of a space to which the light illumination portion illuminates light. The main control module may be capable of communicating with an external device by a wireless communication and may control the light control portion according to a control signal from the external device. The first connector may be provided in the main control module and may connect the main control module and the sensing portion. The sensing portion may include a switch by which an operating signal of a user is input. Accordingly, a user is capable of conveniently using a sensor and a switch together.
