Description

Technical Field

[0001] The present invention relates to a light emitting diode system, and in particular to a light emitting diode system for receiving wireless signals. Background Art

[0002] Currently, common LED systems include two types: series-connected LED systems and parallel-connected LED systems. Both series-connected LED systems and parallel-connected LED systems require multiple power lines and signal lines, which wastes wires. Later, technologies were developed to transmit light signals over power lines to save signal lines. The light signals include light data and data.

[0003] When the LED driver of the LED system is manufactured, local data must be recorded into the LED driver. When the LED driver receives the light signal, it checks whether the data in the light signal is the same as the local data of the LED driver. If the data in the light signal is the same as the local data of the LED driver, the LED driver drives the LEDs of the LED system to emit light according to the light data in the light signal.
