FIELD: electric engineering.
SUBSTANCE: according to the invention, in lighting device containing at least two light-emitting diodes 1 or light-emitting diode matrix consisting of several branches, or group of individual light-emitting diode matrixes, secondary electric power supply 2 and light-diffusing element 3 the light-emitting diodes or branches of light-emitting diode matrix, or individual light-emitting diode matrixes are connected antiparallel to each other and connected to output of secondary electric power supply through in-series capacitor 4. Secondary electric power supply is made in the form of adjustable alternating current source, and light-diffusing element is provided with additional phosphor coating 5.
EFFECT: enlarging application area of lighting device.
