| Abstract in different language: | More and more light applications use multiple light emitting diodes to generate defined light spectra. Often reaching defined brightness levels and an exact color coordinate or color temperature is desired. The LEDs change their light spectra over time or under influence of different environmental temperatures. One possibility is to compensate the resulting color shift of the illumination by integrating a color sensor. Before the light can be re-adjusted or regulated, a precise color measurement must be guaranteed. This paper studies the color measurement accuracy, based on specific filter curves of sensors and models of red, green, blue and white LEDs fitted to measure data. |
