Abstract

The present invention belongs to the field of LED control technologies, and in particular, to an LED parallel-connection lamp control system and a parallel-connection lamp control circuit thereof. The parallel-connection lamp control circuit provided in the present invention is applicable to an LED parallel-connection lamp control system. The circuit comprises a display data relay module, a protocol decoding module, an address data relay module, and a display driving module. The address data relay module receives address data, and forwards the address data to the protocol decoding module to form an address code for the address data, and outputs new address data. The display data relay module receives a display data stream. The protocol decoding module captures corresponding display data according to the address code, outputs the display data to a lamp control module to drive a lamp to work. At the same time, the display data relay module outputs remaining display data. An entire lamp control circuit implements a function of continued formation of an address code, and may further extend an LED parallel-connection lamp control system into an LED serial-connection, parallel-connection lamp control system.

Description

technical field [0001] The invention belongs to the technical field of LED control, in particular to an LED parallel lamp control system and a parallel lamp control circuit thereof. Background technique [0002] From the topological structure of data transmission, the LED lighting control system can be divided into series type and parallel type. Among them, the display data of the LED series lighting control system is transmitted step by step from front to back, that is, the Nth level series lighting control circuit receives the display data stream output by the N-1st level series lighting control circuit, and intercepts the display data of this level. It is used to control the lamps connected to it to display corresponding effects, and then perform shaping and other processing on the remaining display data, and output them to the N+1th level series lamp control circuit. [0003] The display data of the LED parallel lighting control system is sent to the display data input ...
