Choice of the optimum operating mode of high power LEDs

Light-emitting diode light sources gain now the increasing distribution. It is caused, first of all, increased luminous intensity and service life of high power LEDs in comparison with lamps. However, there are some difficulties with heat removal, allocated with high power LEDs. Increasing the working current cause increasing the luminous intensity and the size of a required radiator. Reduction the working current of high power LEDs leads to increase in quantity of LEDs. The choice of a high power LEDs working current is considered in this article.
