The utility model relates to a wireless network light control technology, concretely relating to a lamp light controller. The lamp light controller is installed on a wireless sensor network consistingof an upper computer, a network controller and a router. The upper computer communicates through a network controller and a lamp light controller; the lamp light controller comprises a control module, a sensor module and a control output module. The control module is used for running a control strategy and being in charge of the communication with other wireless devices; the sensor module is usedfor collecting information of intensity of Illumination and personal activities in the range of the sensor module; and the control output module is used for controlling the on-off of lamps. The utility model is suitable for the energy-saving reconstruction of large-scale buildings, the on-off of lamps can be controlled according to the information of ambient brightness and personnel activities, running energy consumption of illuminating systems can be reduced, and a great deal of wire laying can be saved and fabricating cost of the system can be reduced because a wireless sensor network technique is adopted.
