Abstract

The present invention provides a switch apparatus for controlling an artificial light source, comprising: a lux level detector operable to detect the lux level of light incident on the lux level detector; and a controller operable to control the switch to turn the artificial light source on if the lux level determined by the lux level detector is below a threshold value, wherein when the artificial light source is turned on, the controller is operable to keep the artificial light source switched on if it determines that the lux level determined by the lux level detector minus a lux level contribution from the artificial light source is below the threshold value, and is operable to switch the artificial light source off if it determines that the lux level determined by the lux level detector minus the lux level contribution from the artificial light source is above the threshold value. By removing the site specific addition of artificial light from any decision to switch the artificial lights on or off, lamp cycling can be prevented.
