摘要:
In a lighting unit for operating lamps (LA1, LA2) of a different color temperature, a number of predetermined color points can be adjusted. The color points are chosen so that the color difference calculated in the CIELAB space is the same for subsequent adjustable color points.
摘要:
In a lighting device equipped with three light sources supplying red, green and blue light respectively, the color and/or intensity of the light generated by the three light sources together can be adjusted by means of adjustment points. The colors corresponding to the adjustment points are chosen so that for a fraction of the adjustment points the color difference calculated in the CIELAB space between the colors corresponding to adjacent adjustment points is the same. An inexperienced user can easily find a desired color setting since the change in color perceived by the user is the same for all the adjustment points belonging to said fraction.
