Abstract
A lighting control system comprises a router installed with a Zigbee gateway, and at least one set of lighting devices; the lighting device includes a Zigbee control module, a power supply module and a lamp; the Zigbee gateway converts a wireless signal received by the router for controlling the operation of the lamp into a digital signal of the Zigbee protocol and transmits the digital signal to the Zigbee control module; and the Zigbee control module converts the digital signal into a control signal required to adjust the lamp, and the control signal controls an electric signal output to the lamp by the power supply module to control the operation of the lamp. Using Zigbee signals to build a lighting control system facilitates ad hoc networking and can realize multi-point control of lamps.
