Paper Abstract

Current white LED color has a wide range of CCT and varying distance to Planckian Loci, which cause different tint in white color. This color variation keeps a number of illumination and indication applications away from LEDs. This article introduces a passive method, adding correction filters, to correct the color and achieve visual equivalence of the LED white light. Efficiency of using correction filters is discussed.
