| description | PROBLEM TO BE SOLVED: To provide an illumination system emitting color mixture light wherein a color position is kept constant by an improved system, and to provide a simple adjustment method for this kind of luminaire. SOLUTION: This luminaire which emits the color mixture light including different color channels has a first basic light source forming a first color channel, a second basic light source forming a second color channel and a sensor device, A photosensor of the sensor device is suitable for detecting the brightness of the light in a continuous wavelength area including the color channels. The sensor device has an evaluation and adjusting device searching for the brightness of the different color channels repeatedly and separately. The evaluation and adjusting device searches for an electrical signal subjected to pulse width modulation which has a modified fundamental period so that the color position of the color mixture light is located in a prescribed area of a CIE chromaticity diagram to evaluate brightness values of the color channels and to carry out the drive control of each color channel.
