With chromaticity difference adjustment
Without chromaticity difference adjustment
Calibration feature for chromaticity
This feature provides consistent color balance without chromaticity difference for interior lightings by calibrating chromaticity difference for LED chips among individuals with LED drive circuit on the circuit board.
Calibration feature for temperature
Temperature sensor on circuit board can adjust electrical current and this prevents multi-color LED from variations of luminosity and chromaticity even when temperature changes.
Control chromaticity and luminance with LIN communication
Chromaticity and luminance of multi-color LED can be controlled with LIN signals which car control system sends.
