Abstract (en)
An LED circuit (2, 3) includes a plurality of (22, 32) LED devices (U0, U1,..., UN), a power supply circuit (21) and a signal control circuit (23, 33). Each of the plurality of (22, 32) LED devices (U0, U1,..., UN) includes an LED unit (U0L, U1L, ... , UNL) and an integrated circuit unit (U0I, U1I,..., UNI) having a specific serial number (0, 1,..., N). The signal control circuit (23, 33) is coupled between the power supply circuit (21) and the plurality of LED devices (22, 32), and transmitting an electric parameter carrying a signal code (ENC1) to each of the integrated circuit units (U0I, U1I,..., UNI), wherein a specific LED unit (U0L, U1L,..., UNL) is driven by a corresponding integrated circuit unit (U0I, U1I,..., UNI) when the signal code (ENC1) corresponds to the specific serial number (0, 1,..., N) of the corresponding integrated circuit unit (U0I, U1I,..., UNI).
