Abstract

The invention relates to a lighting system (10), a controller (100) for use in the lighting system, a light sensor (20) for use in the lighting system, a method of determining the contribution of the light emitted by the light source (30) to an illumination level and a computer program product. The lighting system comprises a light source for emitting modulated light (40), a light sensor for sensing the illumination level over time to capture the modulation of the modulated light, and a controller being configured for receiving a sense signal (SS) and for receiving a parameter (P) defining the modulated light to determine the contribution of the modulated light to the sensed illumination level. The effect of the measures according to the invention is that due to the known modulation of the modulated light emitted by the light source, the contribution of the light source in the sensed illumination level can be reconstructed relatively accurately.
