The invention relates to a lighting system (10), a method of controlling the lighting system and a computer program product. The lighting system comprises a light source (30), a controller (100) for controlling the light source (30), and a light sensor (20). The light source is configured for altering a spectrum of the light emitted by the light source. The light sensor is arranged for sensing spectral information comprising at least two different portions of a spectrum of light impinging on the light sensor. The controller is configured for receiving a sense signal (SS) and for generating a drive signal (DS) supplied to the light source to determine the spectrum of the light emitted by the light source in dependence on the spectral information from the light sensor. The effect of the measures according to the invention is that the sensing of the spectral information of the light impinging on the light sensor enables the controller to adapt the color temperature of the light emitted by the light source such that the perceived color temperature more closely corresponds to the intended color temperature. |
