Abstract (en)
A light fitting is provided with a first connector piece arranged to support a light module (20) and provide power thereto, and an input connected to a power source and arranged to provide a power signal to an output comprising a primary coil (15). The primary coil (15) is also operable to transmit a switch signal (60) and the power signal is non-zero irrespective of the switch signal (60). A light module (20) is provided comprising a sealed light housing, a light source (160), a back-up battery (40), a controller (150) and a second connector piece having a secondary coil (25). The secondary coil (25) also receives the switch signal (60) and the controller (150) controls power delivery to the light source (160) in response to the switch signal (60) thereby to turn the light on and off. The light fitting and the light module (20) are arranged to present the primary coil and the secondary coil for inductive coupling therebetween.
