Permanent color consistency over all light sources
For the sensor-based color control for multi-channel LEDs, each lighting unit receives its target value from your smartphone via Bluetooth. The sensor measures the current LED-light and transmits the color value to the microcontroller of the box. The micro-controller compares the current value with the value of the target and calculates the new LED driver signals. This process is so quick that visually it is imperceptible. The color adjustment appears to be completely flicker-free. So with just a tap on the color triangle on your tablet or smartphone, all the light units display exactly the same under the same light or run synchronously in the scenario. Color uniformity is thus guaranteed across all units and within a unit for its lifetime. The system consists of simple standard components that are not especially focused on stability. Only the sensor in the system controller possesses the stability to endure without drift for the lifetime of the unit. The "closed-loop" with the sensor perceives all disruptions in the lighting system that affect the color or brightness as quasi-independent factors. Drifts of the LEDs and of the driver, mechanical tolerances of the optics and of the mechanics are perceived as spectral shifts of the light and are adjusted according to the target color. The electronics work so quickly that the adjustment is flicker-free, i.e. with no visible effect.
