Address setting and signal transmission method and LED module based on the power line working condition
View Patent ↗An address setting and signal transmission method and LED module based on the power line working condition comprising: inputting a signal flow via a power line; demodulating, by a demodulator, the signal flow into a voltage signal and a coded signal; parsing the coded signal into an address coded signal and a control coded signal; and performing address writing on the address coded signal by a first data processor to form a comparative address database and then storing same in memory. The desired light-emitting effect is obtained by means of a second data processor processing subsequent coded signals according to the comparative address database and outputting same to a load. In an LED module made according to this method, the number of power line beams is saved, and coding location of the address of a lamp bead string is implemented easily by means of coding.
