Time is going on so fast , we have design a new LED Chip again , what is  it ?, it is LC8812B WWA , a smart CCT LED Chip, 

it is different from the LC8812B RGB,  All of the color is White color , the Color parameter is on the following 

                                                         WWA: White Color,

                                                  W: BW Blue White 6000-7000K,

                                                    W: WW Warm White 2700-3000K,

                                                   A: A Amber 1800-2000K, 

   the Color Range is from 1800-7000k , as it is smart , so you can mix the color temperature from 18000-7000k as you want . 

   By the way , it have same protocol as LC8812B RGB, so that most of the controller in the market can control it . and the The frequency of PWM can reach 1.2khz too .  The data structure of 24bit is on the following
