The invention discloses a lighting control device for realizing the transmission of a DALI (
digital addressable lighting interface)
bus protocol through ZigBee, which comprises a DALI joint, a DALI
bus transceiver unit, a FLASH-containing
microcontroller, a ZigBee
wireless transceiver module, a 2.4 G antenna and a
power module, wherein the DALI joint is used for outputting DALI
bus control signals, the DALI bus
transceiver unit is used for carrying out mutual conversion on a TTL (
transistor-
transistor logic) level and a DALI difference level, the ZigBee
wireless transceiver module is used for carrying out ZigBee
wireless data transmission, the DALI joint, the DALI bus transceiver unit, the
microcontroller, the ZigBee
wireless transceiver module and the 2.4 G antenna are sequentially connected, and the
power module is simultaneously connected with the DALI bus transceiver unit, the
microcontroller and the ZigBee
wireless transceiver module. The lighting control device disclosed by the invention not only has a wireless ZigBee receiving function, but also can carry out addressing on lighting equipment according to the DALI bus protocol, and control the lighting state of the lighting equipment, therefore, the lighting control device can effectively meet the large-scale, high-
scalability requirements of
intelligent lighting control systems.
