FIELD: electricity.SUBSTANCE: LED radiator circuit is added by N keys and the ring impulse generator having N outputs, each of which is connected to the control inputs of keys, and cathodes of each of N light-emitting diodes through power electrodes of keys are connected to the negative output pole of the driver. The use of keys 4.1, 4.2, ? 4.N and the ring impulse generator 3 ensures reliable functioning of the offered LED radiator when using only one driver that will significantly reduce its cost.EFFECT: improvement of reliability of LED radiator and reduction of its cost.1 dwg |
