An RGB color sensor today can be used in a wide variety of lighting applications. Typical examples include industrial lightning, biomedical equipment displays, chemical analysis, TV backlight control, automotive interior and exterior lighting, and decorative or “mood” lighting.
But, in fact, a color sensor with integrated RGB color filters can do much more. This article shows how all the colors within the color gamut formed by red, green, and blue constants in a CIE plot can be measured and mapped with an RGB color sensor.
This RGB sensor can also monitor the color output of LEDs in a display and/or provide feedback to maintain a reference color. Finally, an RGB sensor will be mapped to measure the color temperature of practical light sources.
