<p>The invention relatives to a lighting system, comprising at least one light source (100) for supplying artificial light and a control unit (120) for controlling the light source. The light source (100) is of the type having an adjustable colour temperature. The control unit (120) comprises means (110) for forming a control signal which is dependent on the daylight level. The control unit (120) is arranged to adjust the colour temperature of the light source in dependence on a predetermined relationship between the daylight level and the colour temperature of the artificial light. Tests have demonstrated that test persons prefer a lighting system in which the predetermined relationship between the daylight level and the colour temperature of the artificial light means that when the daylight level, measured on an office desk, increases from approximately 400 lux to approximately 800 lux, the colour temperature increases from approximately 3300 K to approximately 4300 K.</p> |
