Abstract (en)

The present invention discloses an LED strip. The LED strip includes a plurality of LED lamps and two power lines. Parallel circuit units that are formed by the plurality of LED lamps and resistors are connected in parallel on the two power lines. LED lamps of a same parallel circuit unit group are in a same direction, but LED lamps of various parallel circuit unit groups are in a reverse direction, and LED lamps in the reverse direction of a same parallel circuit unit may be combined in an interleaving way as required. The LED strip controller includes a control signal generation unit and a drive unit. The control signal generation unit and the drive unit are supplied by a power supply circuit. The control signal generation unit provides drive signals to at least one group of drive units alternatively or simultaneously. The drive unit drives the LED strip. In the present invention, a combination of different light-emitting states of the LED lamps is implemented in a two-wire-two-path way.
