Figure 4 and three kinds of lamp brightness dimming progression relationship

Formula (1), L is the brightness, W, O and B are white lights, orange lights and blue lights PWM waveform high time series, dimming cycle of 500μs, high time series is (7FFF) 16 = (32 767) 10.

T8 Tube

High time series such as white light is 7EE0, it dimming PWM waveform is high time:

3.4 Closed-loop color control

Depending on the fitted curve at a constant temperature and backlight fitted curve and make the temperature uniformity of the backlight case, the entire luminance range dimming standard white light can be obtained. However, to ensure constant temperature of the backlight LED light is not possible, as the LED lights temperature changes, white light, orange light, and blue light attenuation is different, the color temperature will drift.  LED Flexi

Record the color sensor 200 dimming cycle, ie 100ms, the red, green and blue three color components of the output pulse count of the data as a three color components brightness value.
