FIELD: electricity.
SUBSTANCE: method includes using multiple contours of current control to excite large number of light diode modules. Each of current control circuits includes at least two transistors connected in parallel to form at least two switching circuits. Each of current control circuits allows or prevents electric current leakage directly downwards along the circuit to the next contour of light diode modules in response to the predetermined level of voltage of the positive part of the voltage source. Appropriate contours of voltage control react at various voltage levels. As a result, to extract light at the specified level of voltage, maximum quantity of light diode modules is excited.
EFFECT: efficient use of electric energy and reduced energy losses.
