Abstract: In this paper we reconstruct the non-linear characteristic of the forward current and the brightness of the RGBW LEDs to the linear characteristic. The forward current value is found to be matched with the same interval in brightness. And it is possible to find a corresponding PWM dimming value. This will provide a means to precisely control the color of the full-color illumination with a RGBW LEDs.
