Abstract (en)
[origin: EP3914045A1] The invention relates to a lighting system (100) with a lighting unit (110) which comprises at least two light sources (111, 112, 113, 114) having different color spectrums, with an optical part (116) which is configured to mix the color spectrums of the light sources (111, 112, 113, 114), with a drive unit (116) which is connected to the lighting unit (110), with a sensor (117) which is arranged in a connection area between the drive unit (116) and the lighting unit (110), and which is configured to detect the junction temperature (131) of the light sources (111, 112, 113, 114), and with a control unit (140) which is configured to optimize a value of color consistency of each of the light sources (111, 112, 113, 114) and to maximize life time of each of the light sources (111, 112, 113, 114), and to act on the drive unit (116).
