PRODUCTION DATA
BC is mainly used for global brightness adjustment to adapt to ambient brightness, such as between day and night, indoor and outdoor.
CC can be used to fine tune the brightness in 256 steps. This action is suitable for white balance adjustment between RGB color group. To get a pure white color, the general requirement for the luminous intensity ratio of R, G, B LED is 5:3:2. Depending on the characteristics of the LED (Electro-Optical conversion efficiency), the current ratio of R, G, B LED is much different from this ratio. Usually, the Red LED needs the largest current. Choose 255d (the maximum value) CC code for the color group that needs the largest initial current, then choose proper CC code for the other two color groups according to the current ratio requirement of the LED used.
