Intelligent LED lamp controller and control method

The invention relates to an intelligent LED lamp controller and a control method. The intelligent LED lamp controller is provided with a parallel connection/serial connection conversion unit which is connected with a decoding module. When all LED lamps are not subjected to address code writing and normally receive data transmitted by a DMX512 signal generator, the input RS485 bus and the output RS485 bus of the lamps are in parallel connection, namely the lamps are connected in parallel to a public RS485 bus through the input RS485 bus and the output RS485 bus to perform data communication with the DMX512 signal generator; and when an addressing device codes address codes for the lamps, the decoding module controls the parallel connection/serial connection conversion unit to change the parallel connection of the input and output RS485 buses in the lamps into serial connection. The intelligent LED lamp controller has the advantages that: the failure of one lamp cannot influence other lamps, and the assembly sequence and positions of the lamps can be changed freely, the lamps are serially connected during automatic addressing, and the lamps of the whole system are communicated in parallel through the buses once the address is coded.
