CONTROL DEVICE AND METHOD OF LOAD CONTROL WITH POLARITY-DEPENDENT VOLTAGE DIVIDER CIRCUIT Russian patent published in 2017 - IPC H05B33/08 

FIELD: machine building.

SUBSTANCE: invention relates to load control device, in particular, light-emitting diode unit, having one or more light-emitting diodes. Result is achieved by fact, that device (60) includes input terminals for receiving input voltage (V10) from external power supply source (16) for load power supply (12), connection device (64) for connection of input terminals to each other and to create current path (66, 68), depending on input voltage polarity (V10), wherein device (64) comprises first current path (66) for connection of input terminals in first direction of current and second current path (68) for connection of input terminals in second direction of current, opposite to first direction of current, wherein each of first and second current paths (66, 68) comprises current control unit (88, 90) to control voltage divider current (I3, I4) in corresponding current path (66, 68) and wherein each of first and second current paths (66, 68) comprises disconnection device (92, 94) to lock voltage divider current (I3, I4) in corresponding current path (66, 68) in reverse direction, opposite to corresponding current direction.

EFFECT: technical result is creation of load control device, particularly by light-emitting diode unit containing one or more light-emitting diodes, which is compatible with various dimmers, in particular, with phase cutoff dimmers.
