LED LIGHTING DEVICE WITH CHARACTERISTIC OF COLOUR TEMPERATURE OF INCANDESCENT LAMP

摘要

FIELD: electricity.;SUBSTANCE: lighting device includes sets of LEDs using natural characteristics of LEDs to bear a resemblance to an incandescent lamp performance at reduction of brightness. Technical result is simpler control. The first set of at least one LED provides light of the first colour temperature, and the second set of at least one LED provides light of the second colour temperature. The first and the second sets are connected in series, or the first and the second sets are connected in parallel, with a resistive element as far as possible with the first or the second sets. The first and the second sets differ by temperature characteristic or have different resonance electric resistance.;EFFECT: lighting device generates light with a colour point parallel and close to a black body curve.;15 cl, 17 dwg
