Abstract

An artificial lighting system (100) comprises a daylight sensor (102) for sensing a level of daylight, artificial light source means (104) for providing a level of artificial light, daylight control means (108) for control of the level of daylight and a controller (106) for control of the level of artificial light dependent on the sensed level of daylight. The controller (106) decreases the level artificial light with increasing level of daylight when the sensed daylight level is below a threshold, and reduces the amount of daylight through control of the daylight control means (108) when the sensed daylight level is above the threshold
